    This invention relates to the making of an underground system for the utilization of geothermal energy, in which an underground liquid pipe is placed. Geothermal energy as an alternative energy source is in the spotlight.
    For example, document NL1002731 discloses a prefab concrete pile with a continuous liquid pipe collapsed therein for connection to a liquid circuit that extends in the ground in order to extract heat or cold from the ground for the building. Document NL1030223 discloses the making of a foundation from piles for a building that must be provided with a fluid circuit that extends into the ground in order to extract heat from the ground. Liquid lines are laid around the bottom end of the piles before they are driven into the ground, so that the bottom end drags the liquid lines along into the ground. As an example of the use of a tubular pile in the construction of an underground heat exchanger, document JP-A-20051388866 discloses a thin-walled steel screw pile with external screw blades at the bottom end which screw the pile into the ground. Above the screw blades, a tube is spirally wound around the outside of the pile, the ends of which run upwards along the outside of the pile to above the ground for connection to a medium circuit, so that the medium in the spiral part of the tube can exchange heat or cold with the surrounding ground. Thus, this JP-A-20051388866 discloses a tubular pile with heat exchanger external to the tubular pile. N2008895 (Flow Capital bv) also discloses a tubular pile with heat exchanger. The prior art discussed above relates to equipping a foundation pile with an underground heat exchanger. The underground heat exchanger will not reach deeper into the ground than the depth that the foundation pile reaches in the ground. As a result, the heat exchanger will not go deeper than 20 meters. In order to provide a ground-based single-family house of usual size in the Netherlands (between 100 and 150 m2 GFA and between 300 and 500 m3 gross content) with sufficient energy from the soil for heating and hot tap water, at least five such foundation piles are each equipped with an underground heat exchanger.
    It is known from practice to install an underground heat exchanger made of a single plastic hose in the form of a vertical hose loop over a depth of 200 meters in the ground by means of soil drilling.
    A single underground hose loop is sufficient for the heat demand of a ground-bound single-family house of usual size in the Netherlands.
    The hose loop is lowered into a ground hole formed by a pipe extending to the final depth, then the pipe is removed and the ground hole filled with a grout-like filler material to seal and isolate the various subterranean water layers from each other.
    As a result, the hose loop becomes embedded in the filling material supplied from elsewhere and introduced into the ground hole.
    Based on everything known so far, the inventor has set itself the goal of developing an improved method and apparatus (e.g., the insertion profile described below) for constructing a system for utilizing geothermal energy.
    As a result, the inventor has come up with a method in which a medium line (for liquid and / or gas) is introduced into the ground by means of a pressure-resistant elongated element (hereinafter also referred to as: “insertion profile”) which entrains the medium line during insertion. and which insertion profile brings the media line to the desired depth in the ground and is subsequently withdrawn from the ground, leaving the media line in place at the desired depth in the ground.
    This medium pipe is intended to form part of a medium circuit for the utilization of geothermal energy.
    For example, with the aid of the medium that flows through the medium pipe, heat or cold is stored in the ground or extracted from it. The medium circuit can be either a closed or an open circuit, in which latter case, medium (liquid or gas) from the surrounding soil. flows in the pipeline and vice versa (aquifer principle). The medium pipe thus placed in the ground can provide a heat exchanger in the ground that exchanges thermal energy with the earth's soil environment in which the medium pipe is placed.
    Preferably, the insertion profile makes its way through the ground and for this reason is preferably equipped with a, preferably permanently mounted, protective profile, for example foot body, and the medium pipe that is entrained by the insertion profile during the passage through the soil. is protected by this foot body against the influence of the surrounding ground. The foot body is preferably mounted in a collapsible manner so that it can pass the medium line unhindered during the withdrawal of the insertion profile from the ground.
    The insertion profile preferably makes a vertically or downwardly extending channel, also called a hole, in the ground, in which the medium pipe is received, preferably by pushing soil downwards and / or sideways so that the free space of the channel is formed in the ground. The insertion profile preferably makes this hole in unprocessed soil (also called virgin or undisturbed soil). The aim is to have the medium pipe have thermal contact with the surrounding soil over its entire length or at least 80 or 90% of its length in the ground, so that contact heat takes place between the ground and the medium pipe.
    The insertion profile preferably forms a hollow space in the ground as it moves through the soil and the medium pipe is drawn into this hollow space through the insertion profile. The insertion profile is preferably at least 5 or 10 or 15 meters long, preferably long possible, possibly a maximum of 25 or 30 or 40 meters long. Alternatively, the length of the insertion profile is at least 1 or 3 or 5 meters longer than the minimum required length of the foundation piles for the soil parcel concerned according to the construction calculations.
    It is preferred that the insertion profile functions as a broker for the medium line. Preferably, this is accomplished in one or more of the following ways: in preparation for insertion, the medium line is extended along the insertion profile, preferably over a length of at least 5 or 10 meters, and this condition is maintained during insertion so that the medium pipe along the length of the above-ground longitudinal portion of the insertion profile supported thereby; during insertion, the medium pipe extends upwards from the ground surface along the longitudinal part of the insertion profile protruding above the ground surface, preferably over a length of at least 5 meters, measured from the ground surface, more preferably over at least 50 or 80 or 90% of the above-ground longitudinal part of the insertion profile. By this extension along the insertion profile, damage or undesired permanent deformation of the medium line is avoided.
    The insertion profile is driven into the ground, preferably by a drive means that acts on the insertion profile, preferably on the end protruding above the ground (hereinafter referred to as "top end"). Driving the insertion profile into the ground can be done in any conceivable way, such as driving, pressing or vibrating or screwing. As a rule, the insertion profile will mainly be driven into the ground in a vertical or upward position.
    Preferably, the invention is applied to a plot with "soft" soil. The term “limp” refers to soil that produces relatively little resistance to the insertion profile during insertion. This is the case, for example, with building land for a building, in particular a house of no more than two or three floors, for which a pile foundation is required, for example a pile foundation of foundation piles with a length of at least 5 or 10 meters. Suitable soil preferably contains no or at most thin layers of sand and / or clay (e.g. maximum 2 meters thick) over the insertion depth of the insertion profile.
    Preferably, at least 50% or 75% of the underground hose loops are placed directly under the associated building, such as a house. Preferably, a minimum of 3 or 5 hose loops are associated with a single building, such as a house, for example a number of hose loops such that a minimum of 150 or 290 meters underground hose length is associated with the building. The minimum 3 or 5 hose loops are connected to the heating system of the building, for example connected to a common collector and / or circulation pump and form an extraction field associated with the building, also called “floor field”, preferably entirely on the building belonging to the building. plot of land. The hose loops preferably maintain a horizontal distance of at least 2 or 3 meters from each other.
    A respective hose loop is thus inserted into the ground in question at least three or five times in succession at locations at least 2 or 3 meters horizontally apart from each other, using the insertion profile which is inserted vertically into the ground and thereby takes the hose loop with it and then out. the ground is pulled leaving the hose loop in the ground.
    A possible insight on which the invention is based is driving hose loops into unprepared soil over a limited depth by means of an insertion profile that can be used again and again, whereby the amount of underground hose required for the heat demand of the building is realized by more than two or three install underground hose loops at a horizontal distance from each other. An underground drilling to a great depth with the accompanying passage of various underground water layers, the use of a lot of rinsing water with an associated cleaning system and the necessary embedding of the hose loop in grout or the like can be avoided. This can lead to a lower environmental risk. Compared to deep borehole, the cross-sectional size of the insertion profile is less restricted. When drilling the soil, the hose loop must fit within a diameter of 140 millimeters (the diameter of the drill pipe). The insertion profile can allow the legs of the U-shaped hose loop to have a mutual spacing of 200 millimeters or more, so that the supply and discharge flows through the hose loop have less influence on each other.
    The tube diameter of the hose loop can be chosen smaller than with deep soil drilling (for example 20 instead of 40 millimeters in diameter), so that a more intensive exchange of heat takes place between inside and outside the hose loop due to a relatively large contact surface.
    The hole made by the insertion profile in the ground does not have to be stringent and the hole closes by itself again, so that no filling material has to be artificially supplied from ground level to the hole to close it.
    The supply and discharge part of the underground medium pipe preferably remains above ground and / or is connected, preferably together with at least 2 or 4 other such medium pipes, to a pumping means and / or above-ground heat exchanger, preferably installed in a building, and / or collector.
    Examples for the medium pipe (from eg.
    PE (polyethylene) or PP (polypropylene) or other polymer), are as follows: a single hose; two concentric hoses, the innermost of which forms the inlet and the annular gap between the innermost and the outermost the outlet, or vice versa; single or double or multiple; a corrugation (internal or external) which increases the surface of the medium pipe for a more intensive heat-exchanging contact with the environment.
    The medium pipe is, preferably together with at least 2 or 4 other such medium pipes, connected to a thermal system, for example space heating or cooling or tap water heating for, for example, bathing and showering, preferably of a single building, for example a house.
    The thermal system can be limited to the building / home in question to which the medium pipe belongs, or it can form part of a shared system, for example a building with apartments or district heating.
    By means of the invention, the position of the medium pipe in the soil can be optimized according to the local conditions.
    Preferably, the part of the medium pipe located in the ground has a substantially U-shape or, in other words, two mutually spaced, straight and parallel pipe parts which are preformed at the deepest point in the ground via a, preferably straight pipe, loop or bend-shaped pipe section (the terms “loop” and “bend” are hereinafter commonly referred to as: “loop”)}). This loop-shaped pipe part preferably has the shape of a segment of a circle, more preferably it describes a semicircle. However, an alternative loop shape is also possible, for example elliptical or angular, for example V-shaped. The loop-shaped pipe part is preferably dimensionally stable or has a permanent shape, for instance by a deforming operation, such as plastic deformation, optionally with heat, for instance by bending, of the relevant pipe part prior to insertion of the medium pipe into the ground. This U-shape of the underground medium pipe is an example of an underground hose loop (also called “hose loop” for short). An underground hose loop in particular contains an underground supply and discharge pipe which are connected to each other at the deepest point so that the hose loop provides a closed medium circuit.
    For the loop-shaped pipe part, one or more of the following preferably applies: has a bending radius of at least 50 or 75, such as for instance 100 and / or at most 200 or 300 millimeters; has a bending radius of at least 2 or 3, such as, for example, 5 and / or at most 10 or 15 times the outer pipe diameter; is assembled as an initially separate part with the connecting straight pipe parts, for example by mirror welding; is undivided of the connecting straight pipe sections.

    For the insertion profile, one or more of the following preferably applies: one-piece; straight; of metal, for example steel; an open profile such as an H or I profile or a trough or trough-shaped profile or a sheet pile profile; a thin-walled beam or profile; two mutually parallel flange plates, preferably with free longitudinal edges, and a web plate between them, with which a channel-shaped space is delimited on three longitudinal sides and a fourth longitudinal side is open; a profile open on a single longitudinal side; a chamfered or pointed end, for example provided by chamfered flange plates, which serves as the bottom or front end (hereinafter also referred to as "bottom end") during driving; contains near the lower end an engaging body (hereinafter also referred to as: "driver"), for example protrusion, for example in the form of a pimple or mushroom, with a shape adapted for entraining the medium line, for example for hooking, preferably releasably, the the loop of the medium pipe; has a width of the web of at least 200 or 300, such as for instance 400 and / or at most 600 or 800 millimeters; due to its nature and / or design not suitable or intended to function as a foundation pile and / or to remain permanently in the subsoil.
    Preferably, one or more of the following applies to the driver: keep a distance from the flanges of the insertion profile, preferably at least 25 or 50 and / or at most 150 or 200 millimeters; is centrally placed between the flanges of the insertion profile; has a distance of at least 50 or 100 and / or at most 300 or 400 millimeters from the foot body; comprises a retaining flange on its side of the insertion profile, so that the medium line engaged by the driver is retained between the retaining flange and the insertion profile; has a surface profile engaging with the fluid line and which is form-fitting with the external profile, for example tubular shape, of the fluid line; is in the form of a bollard-shaped mooring post with a thickened or widened head with preferably rounded corners; provides line contact with the loop, preferably over a minimum of 80 or 90 or 95% of the loop length; only has an engaging or retaining action, such as hooking action, on the fluid conduit during forward movement of the insertion profile with the lower end facing forward.
    For the foot body, one or more of the following preferably applies: provides a closure at the lower end of the insertion profile; is located between the bottom end and the driver, relative to the longitudinal direction of the insertion profile; is pivotally mounted, preferably about an axis perpendicular to the longitudinal direction of the insertion profile; has a collapsed position, preferably flat against the insertion profile, and an expanded position, preferably oriented transversely to the insertion profile, preferably projecting slightly obliquely backwards; comprises a flat plate and / or is made of metal, preferably steel; is collapsed on the side of the medium pipe that faces the insertion profile during retraction of the insertion profile.
    Preferably, one or more of the following applies during the insertion of the medium pipe into the ground: the medium pipe is received in a channel-shaped space of the insertion profile, which is, for example, formed between the opposite flanges of the insertion profile and / or rests against a wall, for example the web plate, of the insertion profile; the medium pipe is temporarily attached to the insertion profile by means of a hook fastening.
    Optionally, a liquid, for instance water, is injected near the lower end of the insertion profile, for instance during insertion of the insertion profile, to make the soil easier to split; and / or during retraction of the insertion profile from the ground to stimulate the collapse of the hole made by the insertion profile in the ground. To this end, the insertion profile is preferably equipped with a supply pipe for this liquid extending longitudinally therealong, which supply pipe preferably debouches near the lower end, for example within a distance of half a meter from the lower end, of the insertion profile, and which supply pipe is or can be connected to a liquid source, which is preferably located above ground. It is preferred not to use liquid injection during insertion and / or removal from the soil.
    The design of the system is favorable to stimulate the collapse of the hole made in the ground by the insertion profile during retraction of the insertion profile from the ground.
    The system can be used in many different locations, for example in the garden, on the land near the farm or under a road. As a rule, a plurality of loops, for instance at least four or six, are used at a distance from each other and, inside or outside the building to be heated, are fluid-technically coupled to each other. In an application, the one or more loops are connected to a transport pipe that connects to the medium pump.
    The invention is advantageously applied at a location with a high groundwater level, for instance less than 5 or 3 or 2 or 1.5 or 1 meter below the local ground surface. Tests have shown that the part of the medium pipe below the local groundwater level quickly and optimally becomes embedded in the surrounding soil after the insertion profile has been withdrawn, so that a lot of heat can be exchanged quickly. Preferably, the insertion profile has such a length that a length of at least 10 meters or at least 50% of the insertion length in the ground is below the local groundwater level.
    A synonym for "medium pipe" is "hose" or "tube".
    For example, the procedure is as follows: At the start of the work, the insertion profile with a length, for example between 15 and 25 meters, lies horizontally on the ground. At the top of the insertion profile, the free end of the hose (possibly wound on the reel) is temporarily attached (e.g. clamped). The driver of the pile driver sets the profile upright and thus the top of the profile moves upwards and the hose moves forcibly along (and is pulled off the reel / reel, if applicable with regard to the reel) When the profile is upright, the hose runs from top to bottom along the profile, forming one leg of the U-shaped hose loop. is now guided around the flange at the bottom of the profile, the vibration is started and the profile slowly disappears into the ground and the hose loop is pulled into the ground, pulling the other leg of the hose loop from the reel (if application regarding the reel) Once the profile is at depth, the other leg of the hose loop is separated (eg cut) from the stock (eg hose wound on a reel). the hose (for example on the reel) is now temporarily attached to the top of the profile. Then the profile is lifted up from the ground (e.g. vibrated). The hose loop that has been brought into the ground through the profile remains in the ground. The top of the profile moves upwards and pulls the attached end of the hose located in the stock (for example on the reel) upwards in preparation for the insertion (e.g. vibrating) of the next hose loop.
    For example, one or more of the following applies to the supply hose: the supply hose is wound on a reel; a construction machine, for example pile driver, is equipped with one or more reel holders, each of which contains a reel with a supply of hose, for example so that the construction machine carries a supply of hose with a length of at least 1 or 5 kilometers; the unwinding of the hose from the reel is driven by the raising of the insertion profile (for example in a manner as described in the preceding paragraph), the free end of the hose wound on the reel moving upwards with the top end of the insertion profile. moves, for example by being attached to that top end.
    The connecting pipes connecting the underground loops to a collection point, for example a collector or circulation pump, are laid in such a pattern so that for all underground loops the length of the respective connecting pipes is equal so that a hydraulic balance is created so that the energy is evenly distributed over the floor field withdrawn from the ground. For a hydraulic balance, an even number of underground loops is preferably used for a floor field. If the connecting pipes are underground, heat can also be exchanged with the ground.
    An example not limiting the protection of the patent is now described with reference to the accompanying drawing.
    FIG. 1 shows a house in perspective; Pig. 2 shows the insertion profile in the insertion position; FIG. 3 shows the insertion profile in the retraction position; FIG. 4 shows a floor field in top view; FIG. 5-7 show an alternative implementation of the insertion profile; FIG. 8 shows hose positioning; FIG. 9 shows a hose guide; and FIG. 10 shows a hose reel.
    Below a house there are medium pipes extending downwards from the ground surface (figure 1 in the drawing) in the ground. The medium pipes 1 are connected via a medium pump (figure 2 in the drawing) to the underfloor heating (figure 3 in the drawing) of the house. Liquid is circulated through the medium pipe 1 with the pump 2.
    The liquid extracts heat from the ground and this heat is then released to the floor of the house. This is done with the intervention of a heat pump for heat and possibly for cold for active cooling (with passive cooling without the intervention of a heat pump). The heat exchanger is preferably a plate exchanger. Each medium pipe 1 has a “U” shape in the ground, whereby the medium pipe runs straight down and runs straight up again via a bend at the deepest point.
    FIG. 2 and 3 show the insertion profile (an H-profile) and a preformed piece of curved U-shaped medium pipe. In the foreground of the display is the pointed bottom end of the insertion profile.
    FIG. 2 shows the situation as during the insertion into the ground. The loop of the medium pipe runs tightly around the carrier. The foot, with which the insertion profile is closed at the bottom end, has a flange part that extends outwardly and away from the bottom end. This flange part forms a screen for the medium pipe.
    FIG. 3 shows the situation as during the withdrawal of the insertion profile from the ground. The loop of the medium pipe is naturally released by the driver and remains in the ground. The foot is folded away by gravity or the surrounding ground so that it can pass through the loop unhindered.
    In fig. 2 and 3 only a part of the medium pipe is shown of the minimum 5 or 10 meters long parallel legs of the “U”. In practice, the parallel legs of the “U” continue from the medium line to or up to or beyond the top end of the insertion profile.
    Fig. 4 shows a collector 4, underground hose loops 5 (eight in number), and connecting pipes © between the hose loops 5 and the common collector 4. The pattern of the connecting pipes 6 is such that the flow path between a hose loop 5 and the collector for the supply and discharge respectively is virtually the same for all hose loops 5, which provides a hydraulic balance.
    According to Figs. 5-7, the folding foot forms the lower end of the insertion profile.
    The hose positioning of Fig. 8 ensures that the legs of the hose loop remain as far away from each other as possible during insertion into the ground. FIG. 8 also shows the insertion profile.
    FIG. 9 shows a hose guide that guides the hose from the hose stock (see hose reel of fig. 10) to the broker.
