    [0002] Concrete water drainage slowdown system
    [0004] The present invention relates to the water drainage slowdown system that slows down the flow of water in a canal or a channel, or a river, and / or that solves the problem of water infiltration.
    [0006] Patent document BE2009 / 0813 offers a perspective of an application of a known system for the construction of a track or a pedestrian path over a canal or a watercourse. This system uses a series of modules that can be placed side by side. Each module contains a set of components, including:
    [0008] - a lower concrete section, with a V-shaped cross section;
    [0010] - partitions to slow the flow of water, and
    [0012] - a sealing part that is located on the upper edges of the lower section.
    [0014] The system interferes with the essential functions of a canal or river, taking into account the sealing parts, which will disturb the vegetation in the canal as well as the life of the animals. The deceleration of the water flow is achieved by means of ordinary partitions. The sides of the channels have to be covered with concrete. The correct positioning of the modules is necessary to avoid the risk of accidents, as well as to obstruct the flow of water. The lower section of the first module can be lowered relative to the lower section of the second module, causing a partition to completely obstruct the water drainage. Inspection of this system is complicated. The water present in the canal remains in the dark due to the sealing parts and is therefore less ventilated. This can lead to the growth of bacteria in stagnant water, such as bacteria from the Legionellales family and / or from the anaerobic family.
    [0016] According to Patent BE2009 / 0813, the system requires the use of large volumes of concrete. Installation of the system is also time-consuming and has to be carried out by specialized professionals.
    [0017] According to the invention, the aim of the system is to solve one or more of the problems mentioned. According to the invention, the system does not interfere with the essential functions of a canal, specifically with the vegetation of the canal, the life of the animals in the canal, the infiltration of the water, the ventilation of the water, etc. The system is also used as a means of solving the floodplain problem.
    [0019] According to the invention, the system itself is a water drainage slowdown system, which contains a substantially vertical wall (3) that is intended to be placed in the canal, channel or river to form a dam or a partition (3) that , in turn, divides the channel, channel or river into an upstream zone (OZ) and a downstream zone (AZ) from the dam or partition (3).
    [0021] The system contains at least one element made of concrete (1), so that the concrete element (1) itself consists, at least, of:
    [0023] - a base (or plate) made of concrete (2) which is preferably at least partially permeable to water (for example, the plate (2) is provided with openings or a hollow part (20)), where the base (2) has a maximum length (LE) of 1 m to 5 m and a maximum width (BR) of 50 cm to 2.5 m; Y
    [0025] - a first dam made of concrete (3) having at least one part (3A) that is preferably substantially impermeable to water, and where the first dam (3) is equipped with at least one system overflow (3C).
    [0027] This element (1) has the shape of a piece, which makes it easier to place the element in the lower part of the canal or river.
    [0029] The element (1) contains and / or is equipped with a transit system (4) made, at least, of porous concrete that forms an interior chamber (40) to collect water, so that the transit system (4) contains an upper part (41) made of porous concrete with an upper surface of at least 100 cm2 that extends below the level of the overflow system (3C), when the base (2) is in a horizontal position, where the transit system contains a discharge system or a discharge means (40A) for the discharge of water that flows into the inner chamber (40) of the transit system (4).
    [0030] Through the transit system, the flow of the water can be better controlled by a pipe or discharge system (70). The flow of the minimum amount of water is no longer dependent on a dam opening or an overflow opening, through which dirty water can flow with a risk of clogging. Furthermore, it is possible to drain water also by connecting the transit system (4) to an outlet pipe, for example, elsewhere in the canal or river, or in a pond. Since water will flow through porous concrete, it will be fairly clean.
    [0032] According to the invention, in the system, the upper part (41) made of porous concrete of the transit system (4) is made from hardened porous water drainage concrete. Water drainage concrete is manufactured by hardening a mixture of at least cement, granulated materials with particle size 6 to 14 mm, and water to achieve an open pore volume of 8 to 12% in porous concrete. hardened water drainage, where the hardened porous water drainage concrete has a water permeability of 0.05 liters / m2 / s to 5 liters / m2 / s, preferably 0.1 liters / m2 / s to 3 liters / m2 / s, and ideally between 0.1 and 1 liter / m2 / s, where water permeability is measured by lowering the water drainage slowdown system (1) with an empty inner chamber (40) for the transit system ( 4) in a tank filled with water up to the level (PT) of the overflow system (3C) of the dam (3) with the base (2) in a horizontal position, and then determining the amount of water that flows in 30 seconds through the upper part (41) made of porous concrete, inside the inner chamber (40) of the transit system (4).
    [0034] The porous drainage concrete (41) serves as a filter element. In this way, the outlet pipe (70) remains clean for the flow of water.

    [0204] - a concrete base (2) (or plate) that is at least partially permeable to water (for example, the plate (2) is provided with openings or a hollow section (20)), where the base ( 2) it has a maximum length (LE) of 1 m to 5 m and a maximum width (BR) 50 cm to 2.5 m; Y
    [0206] - a first concrete dam (3) has at least one part (3A) which is substantially impermeable to water, so that the first dam (3) is equipped with at least one overflow system (3C).
    [0208] The size of the openings (20) is advantageously adapted for the growth of grass, and other aquatic plants, thus guaranteeing a good permeability of the soil to water under the base (2)
    [0210] Therefore, this element can be loaded onto a truck for transportation to the place where the element has to be installed, to act as a dam (3) resulting in slowing the flow of water.
    [0212] This element (1) is in the form of a concrete element, which makes it possible to facilitate the placement of the element in the lower part of the channel or drainage pit or river.
    [0214] The element (1) contains and / or is equipped with a transit system (4) that is manufactured from, at least, a porous concrete that defines an interior chamber (40) to collect water, so that the system transit (4) has an upper part (41) made of porous concrete, which has a surface of at least 100 cm2, which is located at a distance (d) of at least 20 cm below the level of the overflow system (3C), when the base (2) is located in a horizontal position, so that the transit system comprises a discharge system to discharge water that flows into the inner chamber (40) of the transit system ( 4).
    [0216] The transit system (4) serves as a means to ensure minimal water drainage for water that is being contained by a dam.
    [0218] With the help of the transit system (4), for example, the flow of water through a pipe or discharge system (70) can be better controlled. The flow of the minimum amount of water is no longer dependent on a dam opening or an overflow opening, through which dirty water can flow with a risk of clogging. Furthermore, by connecting the transit system (4) to an outlet pipe (70), the water can be drained further away from the dam, for example to a position downstream of the canal or river, or to a water reservoir. water or a pond downstream. Since water will flow through porous concrete, it will be fairly clean.
    [0220] In the system according to the invention, the upper part (41) made of porous concrete of the transit system (4) is made from hardened porous water drainage concrete. Water drainage concrete is manufactured by hardening a mixture of at least cement, granulated materials with particle size 6 to 14 mm, and water to achieve an open pore volume of 8 to 12% in porous concrete. hardened water drainage, where the hardened porous water drainage concrete has a water permeability of 0.05 liters / m2 / s to 5 liters / m2 / s, preferably 0.1 liters / m2 / s to 3 liters / m2 / s, and ideally between 0.1 and 1 liter / m2 / s, where water permeability is measured by lowering the water drainage slowdown system (1) with an empty inner chamber (40) for a transit system ( 4) in a tank filled with water up to the level (PT) of the overflow system (3C) of the dam (3) with the base (2) in a horizontal position, and then determining the amount of water that flows in 30 seconds through the upper part (41) made of porous concrete, inside the inner chamber (40) of the transit system (4). (see figure 8)
    [0222] The porous drainage concrete (41) serves as a filter element. In this way, the outlet pipe (70) remains clean for the flow of water.
    [0224] The first dam (3) has a first side (35) that is directed towards the transit system (4) and, with respect to the first side (35), a second opposite side (36), so that, at least along the first side (35) and / or along the second side (36), the slowdown system comprises, at least, one reinforcing element (50, 50bis) of concrete supported on the base or plate (2 ). This is beneficial for forming a solid element (1). The reinforcing element (50) can also be provided with anchoring elements (80) for lifting the system according to the invention and the construction of the system or of the lower part of a channel. Furthermore, if the reinforcing element (50) extends along the side of the dam (3), the reinforcing element (50) serves as a means to prevent lateral water flow along the edge (3R). of the dam (3) in the vicinity of the lower part of the canal or in the vicinity of the base (2). The reinforcing element (50, 50bis) is also beneficial for the transportation of water drain slowdown systems by trucks, since the systems can be transported with the base (2) in a substantially vertical position.
    [0226] The reinforcing element (50, 50bis) forms at least one step or ladder along the first and / or the second side (35, 36). This is beneficial for safety. Of course, slowing the water drainage will raise the water level, at least, along the side of the dam (3). The step or ladder is a tool for people or animals to get out of the channel filled with water. The steps also guarantee the minimum disturbance to the animals due to the formation of the dam (3) in the canal, river or bed.
    [0228] The first dam (3) comprises two opposite sides (35, 36), so that the first dam (3) is provided, along both sides (35, 36), with a reinforcing element (50, 50bis) that forms a step or a ladder. Thus, there is a means of egress for people and animals on both sides of the dam (3). The step or ladder is also beneficial for channel maintenance, as professionals or workers can easily enter and exit a channel, without damaging the ground side of the channel. channel.
    [0230] In the form of implementation of figure 1, the slowdown system contains a second wall (6, 51) of concrete supported on the base (2) to form a second dam (6), so that the second wall (6) it is far from the first dam (3), where the second wall (6) has a height that is preferably less than the height of the first dam (3). The base (2), the first wall or dam (3) and the second wall or dam (6) are part of a single concrete element (1). The first dam and the second dam (6) may be equipped with anchoring means (80) to facilitate lifting and positioning of the system in a canal.
    [0232] The second wall (6) adjusts to form at least one step along the first wall (3) of an adjacent water drainage slowing system according to the invention. The second wall (6) also acts as a reinforcing means for the first wall (3) of an adjacent water drainage slowdown system according to the invention.
    [0234] The base or plate (2) is extended by a foot element (21) adjacent to the first wall (3). The foot element forms a support for the base (2) of an adjacent water drain slowing system according to the invention.
    [0236] The concrete base (2) has a substantially trapezoidal shape, having (a) a first end with a first width (B1) located next to the first dam (3), and (b), relative to the first end, a second opposite end with a second width (B2), so that the second width is at least 20%, preferably at least 30% less than the first width.
    [0238] The foot member (21) is equipped with a recess (210) that adjusts to accommodate the second end of an adjacent water drain slowdown system. The placement of adjacent systems is then simplified.
    [0240] The first dam (3) is equipped with a porous part (3B) that has been moved away from the base (2). The section (3B) is positioned, for example, under the overflow opening (3C).
    [0242] The base or plate (2) is substantially a flat concrete plate (2), which is not equipped with longitudinal inclined concrete walls. The base (2) is intended to cover the lower part of the channel. According to the invention, the system is not equipped with a concrete section along the sides of the canal.
    [0244] The inner chamber (40) of the transit system (4) (which is positioned along the second dam (6)) comprises a drainage element (44). For example, the drain element (44) is placed in the mold for casting the porous concrete that does not flow into the drain element. The inner chamber (40) of the drainage element (44) forms, in this case, the inner chamber (40) of the transit system (4). The drainage element (44) is, for example, a drainage tube with a perforated wall, where the outer surface of the tube is equipped with a textile or fiber layer or layer, permeable to water.
    [0246] The drainage element (44) extends between the first end (44A) and the second end (44B), so that at least one of the first and second ends is equipped with a coupling element to connect the end to outlet pipe (70). The outlet pipe (70) is located, for example, next to the channel (for example, a lower layer of the soil or below the bottom of the channel, at a level that is below the level of the base (2)) .
    [0248] The base (2) is made, at least partially, of porous concrete and / or has one or more openings (20), through which water can flow. The openings (20) are preferably positioned in the central section of the plate (2). The size of the openings is adjusted, for example, for growing plants. The presence of plants along the bottom of the channel is advantageous for water infiltration.
    [0250] Both ends (44A, 44B) of the drain tube (44) are provided with a coupling element (40A), which is suitable for connection to the outlet pipe (70) and / or to the sealing compound (71) or the sealing cover.
    [0252] The dam (3) is preferably wider than the plate (2), which is beneficial to prevent the lateral flow of water from the channel. This is also advantageous for the stability of the soil on the channel side.
    [0254] In the embodiment of Figures 5-7, the multiple slowdown transit systems are connected to a single drain pipe (70). The drain pipe (70) is located below the level of the plates (2). The pipe (70) carries the water to a pond, a river, a water reservoir, etc.
    [0255] The embodiment of Figures 9 to 13 is similar to the embodiment of Figures 1 to 7.
    [0257] In this embodiment, the plate or base (2) is rectangular. The plate (2) is equipped with a single dam (3). The dam is equipped along both opposite sides (35, 36) with a transit system (4bis, 4ter). The transit systems (4bis, 4ter) are similar and are connected together through an inner tube (40A).
    [0259] The slowdown systems can be placed in juxtaposition, resulting in that a plate (2) of a first system supports itself on a plate of a plate (2) of a second system. The plate (2) and the dam (3) are provided with anchoring means (80) for moving and lifting the systems.
    [0261] Figure 14 indicates the placement of systems, according to figure 14, on a truck (V). The systems (in a vertical position) can be placed one on top of the other for transport.
    [0263] In the embodiment of Figures 15 to 17, the openings (20) are substantially rectangular.
    [0265] In the embodiment of Figure 18, the drain element (44) includes an inlet opening (44A) and an outlet opening (44B), which allow the drain element (44) to be part of a discharge system of water (70).
    [0267] In the embodiment of Figure 19, the systems are placed side by side, without the support of a board from one system on a board from another system (2).
    [0269] Figure 20 shows a sectional view of a channel, which is provided with systems according to figure 19.
    [0271] The transit systems (4) can be manufactured by placing a drain tube (44) (closed at both ends (44A, 44B) by means of a removable cover (71)) in a casting mold (100). Next, the porous concrete is cast in the casting mold, so that the drain tube (44) is inserted into a layer (101) of porous concrete.
    [0273] For the formation of the first dam (3), the plate (2) and the second dam (6) of the system according to FIG. 1, a casting mold (200) can be used, for example. After the By placing the transit system of Figure 22 in the casting mold of Figure 24 in the gap (202), concrete can be cast into the casting mold (200). After minimal hardening of the cast concrete, the system can be lifted.
    [0275] Figure 25 shows another water drainage slowdown system to slow down a flow of water in a canal, bed or river, containing a substantially vertical wall (3) that is intended to be placed in the canal, bed or river, to form a dam (3) that divides the channel, channel or river into an upstream zone (OZ) and a downstream zone (AZ) with respect to the dam (3).
    [0277] The slowdown system contains at least one element made of concrete (1) consisting of at least one
    [0279] - a concrete base (2) that is substantially impermeable to water, where the base (2) has a maximum length (LE) of 1 m to 5 m and a maximum width (BR) of 50 cm to 2.5 m;
    [0281] - a first concrete dam (3) of substantially trapezoidal shape, having at least a lower part (3A) that is substantially impermeable to water, while an upper part (3B) is permeable to water, so that the first dam (3) is equipped with at least one overflow system (3C) (upper edge of upper part 3B), and
    [0283] - a second trapezoidal dam (6) made of concrete which is substantially impermeable to water.
    [0285] The base (2) comprises, at least, one porous concrete transit system (4), which defines an interior chamber (40) to collect water, so that the transit system (4) has an upper part (41 ) of porous concrete with an upper surface (41B) of at least 100 m2 below the level of the overflow system (3C), when the base (2) is in a horizontal position, where the transit system comprises a system discharge outlet or discharge means (40A) for discharging water flowing into the inner chamber (40) of the transit system (4).
    [0287] The upper part (41) of the transit system (4) is made of at least one porous concrete that is made of hardened porous water drainage concrete, which is made by hardening a mixture of at least cement, granulated materials with particle size from 6mm to 14mm, and water to achieve 8-12% open pore volume in water drainage hardened porous concrete. The hardened porous water drainage concrete has a water permeability of 0.05 liters / m2 / s to 5 liters / m2 / s, preferably 0.1 liters / m2 / s to 3 liters / m2 / s, ideally between 0, 1 and 1 liter / m2 / s, so that water permeability is measured by lowering the water drainage slowdown system with an empty inner chamber (40) for the transit system (4) in a water tank (T ), which is filled with water up to the level of the overflow system (3C) of the dam (3) with the base (2) in a horizontal position, and then determining the amount of water that flows through the part upper (41) of porous concrete in 30 seconds inside the inner chamber (40) of the transit system (4).
    [0289] The water permeable upper part (3B) is also manufactured from a hardened porous water drainage concrete. Water drainage concrete is manufactured by hardening a mixture of at least cement, granulated materials with particle size 6 to 14 mm, and water to achieve an open pore volume of 8 to 12% in porous concrete. hardened water drain. The hardened porous water drainage concrete has a water permeability of 0.05 liters / m2 / s to 5 liters / m2 / s, preferably 0.1 liters / m2 / s to 3 liters / m2 / s, ideally between 0, 1 and 1 liter / m2 / s. The water permeability of the wall (3) is measured by sealingly closing the open side walls, between walls 3 and 6, by sealingly closing the discharge means (40A), and placing the slowdown system in a tank of water, which is filled with water up to the edge of the overflow (3C) of the dam (3) (the base is located in a horizontal position). The amount of water flowing through the porous dam (3) in 30 seconds is then determined.
    [0291] The amount of water that flows through the dam in 30 seconds (measured according to the description above) is preferably 2 to 5 times greater than the amount of water that flows through the discharge means (40A) in 30 seconds (measured as disclosed above in the description).
    [0293] When riverbed water flows through the dam (3), the water level rises in the upstream zone (OZ) of the dam (3). The water then flows through the upper water-permeable part (3B) of the dam (3) into the intermediate zone that is formed between the dam (3) and the wall (6). Then the water level rises more in the upstream zone than in the intermediate zone. The water in the intermediate zone flows through the leveling agent (40A). The wall (6) forms the second dam to slow down the drainage of water.
    [0294] The water level in the intermediate zone increases in relation to the water level in the downstream zone (AZ) behind the wall (6).
    [0296] With such a water drainage slowdown system, the water drainage slows down through the water-permeable dam (3), through the wall (6) that forms a water-impermeable dam and through the transit system (4 ). Water infiltration into the soil is still possible, for example in the intermediate zone.
    [0298] The upper surface (41B) is between 2 and 30 cm, preferably between 5 and 20 cm below the level of the overflow system (3C).
    [0300] The transit system (4) may have a side that extends along the wall (6) to form a reinforcing element for the wall (6).
    [0302] The discharge system or discharge means (40A) is between 5 cm and 30 cm above the base (2), with the base (2) in a horizontal position.
    [0304] The first dam made of concrete (3) comprises a lower part (3A) substantially impermeable to water and an upper part (3B) permeable to water, where the upper part (3B) permeable to water has a lower edge (3B1) and where The discharge system or discharge means (40A) is above the level of the lower edge (3B1) of the water-permeable part (3A) of the first dam (3).
    [0306] The slowdown system comprises a second concrete wall (6) supported on the base (2) to form a second dam (6) on the base (2), so that the second wall (6) is far from the first dam (3), where the second wall (6) has a height that is preferably less than the height of the first dam (3) (for example, 5 to 10 cm apart). The height of the wall (6) can also be equal to the height of the dam (3).
    [0308] The embodiment of Figures 27 to 30 is similar to the embodiment of Figures 25 and 26, with the exception of a few adjustments:
    [0310] - the transit system (4) is located next to the wall (6) and forms a reinforcing element for the wall (6);
    [0311] - inclined side walls (25, 26) extend between the first dam (3) and the second concrete wall (6), where the side walls form lateral reinforcement elements. The side walls are preferably connected to the base (2). The side walls are preferably made of waterproof concrete. The lateral walls have a height that is greater along the dam (3) and the wall (6). For example, there is a system of stairs (251,261) formed along the wall (6) and / or the dam (3).
