Furthermore, the invention relates to a piping arrangement and / or tunnel arrangement, which is subdivided into separate sections. Furthermore, the invention relates to a separating element for such a pipeline arrangement or tunnel arrangement.
    Background Tunnels or pipelines are known as traffic routes for vehicles, in particular for automobiles, railways, overhead railways (MAGLEV) and subways. In the case of pipelines, these may be partially evacuated to allow very high speeds to be achieved by the vehicles running in the pipelines.
    DESCRIPTION OF THE INVENTION The object of the invention is to improve the safety in tunnels or in pipelines which serve as traffic routes for vehicles.
    This object is achieved by the method according to claim 1.
    Characterized in that are formed by the inflation of the at least one separating element separate tunnel sections or pipe sections, vulnerable areas can be separated from other areas in a simple and rapid manner.
    In particular, this can serve as a fire protection measure when the at least one separating element is inflated in case of fire to keep a section of the tunnel or pipe fire-free and smoke-free. Also, the method is advantageous when the partition is provided as a seal in a tunnel or pipe in which trains can travel at high speed in a vacuum. In particular, sections with vacuum can be sealed against a section with normal pressure.
    It is preferred if the inflated separator frictionally fixed in the tunnel or tube, resulting in a particularly simple design. But it is also possible that the inflated separating element and the tunnel profile or the tube profile are designed so that at least partially results in a positive connection between the separating element and the tunnel or the tube. Further, it is preferred that the tunnel or pipe profile is provided in the region of the separating element with mold elements in order to improve a sealing engagement of the separating element on the inside of the tunnel or of the pipe.
    The invention is further based on the object to provide an improved piping arrangement and / or tunnel arrangement for a means of transport.
    This object is achieved with the features of claim 7.
    By at least one inflatable separation element, which is arranged and configured such that it leaves the tunnel or pipe cross-section of at least one tunnel or pipe for the transport in the inflated state and the inflated state tunnel or pipe cross-section over a Substantially full predetermined predetermined length, so as to form separate sections in the tunnel or pipe, a simple and rapid division of the tunnel or the pipe can be made into separate sections. By the inflator, the separating element is inflated, which is triggered by the control device.
    Preferably, the piping assembly and / or tunnel assembly is provided with a plurality of partition members spaced along the at least one tube and / or tunnel, allowing the corresponding partitioning into a plurality of sections. Thus, in case of fire, a narrowly defined partitioning of a section can be made possible and in a pipeline or tunnel arrangement for high-speed trains in vacuum, a plurality of sections can be provided in which normal pressure can be created without affecting the vacuum in the other areas of the arrangement becomes.
    Preferably, the inflator on at least one pyrotechnic gas generator and / or at least one source of pressurized gas. This can cause a rapid inflation. For a longer-term maintenance of the pressure in the separating element, in particular, a pressure source with a pump can be provided. The control device is preferably equipped for receiving and evaluating signals from air pressure sensors and / or signals from fire sensors in order to enable automatic triggering of the inflation in the event of a fire or at best during a pressure increase or pressure drop in a pipeline or a tunnel. Triggering can also be done manually by personnel in the operations center. This possibly based on the mentioned signals and their evaluation by the control device and possibly based on images of cameras arranged in the tunnel.
    Preferably, the pipe assembly and / or tunnel assembly is provided with at least one fitting which changes the pipe profile or the tunnel profile in the region of the separating element in order to effect a sealing engagement of the inflated separating element in the tunnel or in the pipeline. It is further preferred that the pipeline arrangement and / or tunnel arrangement comprises fire protection seals, in particular intumescent fire protection seals, which are arranged in the inflated separating element lying between the outside of the separating element and the tunnel wall or the pipe wall. It is particularly preferred if the mentioned fittings are provided with the fire protection seals. Furthermore, it is preferred if the tunnel or pipeline device has at least one bypass space or protective space for persons separated by fire protection doors and / or airtight doors in the region of a partition element.

    BRIEF DESCRIPTION OF THE DRAWINGS Further embodiments, advantages and applications of the invention will become apparent from the dependent claims and from the following description with reference to the figures. Showing:
    Figure 1 roughly schematically a horizontal longitudinal section through a part of a tunnel with an inflated separating element.
    Figure 2 is a schematic view of a part of a traffic route, which is formed of a plurality of tunnels or pipeline parts, with marking of those points at which separating elements can be arranged;
    3 shows a vertical cross section through a tunnel or a pipeline with funding for a magnetic levitation railway.
    Fig. 4 is a detail view of Fig. 3; and
    Fig. 5 shows a further, roughly schematic vertical longitudinal section through a tunnel.
    Method (s) for carrying out the invention In order to explain an example of the invention, FIG. 1 shows a plan view of a horizontally cut-open, roughly schematically represented tunnel 1, which in this example is shown as a tunnel for traffic with lane 2. In the tunnel, a separating element 10 is shown, which divides the tunnel into the two sections 20 and 21. The separating element is an inflatable element which, when not inflated, is arranged folded on one side or on the ceiling of the tunnel and, in the folded state, leaves the traffic space free. In the inflated state shown schematically, the separating element completely fills the tunnel and settles against the tunnel wall. Instead of a separating element 10, a plurality of elements could also be provided which directly adjacent to one another or at a distance from one another together form the separating element at this point in the tunnel. This is indicated by the broken lines to show that the separating element 10 could be formed by two separate elements 11, 12. It can also form more than two elements together the separator 10.
    The separating element is formed from a gas-tight material or composite material to allow its balloon-like inflation. Furthermore, the separating element is formed of a material or composite material, which has the appropriate fire resistance for the application of the separating element as a fire-resistant separating element to withstand the temperatures occurring in a fire in the tunnel for a predetermined time. Thus, in this example, the separating element may consist of aramid material or comprise such material.
    For inflating the separating element, an inflator 4 is provided. This may provide the gas needed to inflate the collapsed separator by one or more pyrotechnic generators and / or gas stored in pressurized bottles. Also, a pump may be provided to effect pressurized air for inflation and, in particular, for maintaining the inflated condition for a longer period of time. In particular, a combination of such means may be provided. Furthermore, a control device 5 is provided, which controls the triggering or the inflation of the separating element. This may be done by activation by an operator, by fire detectors connected to the controller, by a higher level controller or otherwise.
    The separator 10 is adapted to the tunnel cross-section, that it comes to lie as close as possible to the tunnel wall in the inflated state. This can be assisted if fittings are provided in the region of the separating element in the tunnel, which improve the abutment of the separating element, which will be explained in more detail below. In principle, it is preferred that the separating element is adapted with its shape to the tunnel cross section, that is, in the case of a rectangular tunnel cross section has a substantially cuboid shape.
    Fire protection seals are preferably provided in the tunnel in the region of the separating element, which cooperate with the separating element in order to separate the sections 20 and 21 in case of fire fire and smoke-tight from each other. Such fire protection seals are known, especially as intumescent seals, and need not be further described here. It is particularly preferred if the mentioned fittings are provided with fire protection seals. These come thereby in close contact with the separating element 10, when this is inflated.
    Preferably, it is further provided that in the region of a separating element in the tunnel in each case a leading from the traffic area escape route is provided. This can be a secured by not shown fire doors and overpressure escape route in the illustrated form a bypass (bypass) 25 of the partition member 10 to be executed, which leads from one tunnel section 20 to the other tunnel section 21. But this can also be an escape route, which leads into a separate security room or in a parallel tunnel tube, which is separated by ventilation technology from the illustrated tunnel tube.
    Fig. 2 also shows roughly schematically a part of a traffic route 30, which is formed from a plurality of pipes and / or tunnels 31. This may in particular be a piping system in which a vacuum prevails and in which high-speed trains run. In particular, trains that are magnetically suspended and driven. The pipelines 32 and 33 can represent the route at escape points and "stations", while the pipe 31 forms a direct route. In this piping system, a plurality of separating elements 10 is provided according to the invention. These dividers each comprise at least one inflatable element which can form a substantially air-tight subdivision of the tube when it is inflated. Thus, an optional subdivision into many sections is possible. If necessary, a section in which a train is located, or a section in which maintenance work is carried out, be supplied with atmospheric pressure and this section is separated on both sides by a separating element from the other regions of the traffic route 30, in which there is still the vacuum , This also makes it possible to quickly return to normal operation, since only the previously separated on both sides by the separating elements section must be pumped out again to produce the desired vacuum. Of course, before the start of operation, the triggered or inflated for a certain time dividers must be removed and replaced with new separators. In one embodiment it can be provided that the separating elements are collapsible, so that they are reusable. In particular, it is preferred that the separating elements automatically fold when the gas in them is discharged. This simplifies maintenance.
    3 and 4 show roughly schematically a vertical section through a pipeline, which are provided for a suspended in lateral rails 37 train. Such MAGLEV (Magnetic Levitation) train concepts are known in the art and these need not be further explained here. In this example, on the one hand, it is shown that fittings 41 and 42 are provided in the pipeline in the region of the separating element. These are shaped so that they form the most suitable contact surface for the inflated separating element. Thus, the airtightness of the subdivision can be well ensured by the separator. If the separating element is also or only intended as a fire protection separation, as explained above with reference to FIG. 1, the shaped pieces are preferably provided with fire protection seals.
    In the example shown, a pipe with vacuum for a MAGLEV train, 37 further separating elements 10 may be provided in the rails, as shown in Fig. 4. Thus, the airtight separation can be ensured for the rail area.
    The respective separating element can be held in the tunnel or in the tube in the inflated state only by frictional force. In a separating element, which separates an evacuated section with approximately 0 bar pressure from a section with 1 bar pressure and which separating element is inflated with, for example, 2 bar pressure and rests against the pipe wall and possibly the fittings, a length of about 12 meters of Sealing element suffice to keep it securely in place in the pipe. But it can also be anchors and / or it can be provided a positive connection between the inflated separating element and the pipe or the tunnel. The diameter of the separating element is adapted to the diameter of the tunnel or the pipe and is therefore also several meters, in particular more than 5 meters, for example.
    If installations are provided in the tunnel or in the pipe, which is usually so, they are designed in the region of the separating element so that they can be pushed aside by the inflating separating element. The destruction of the installations can be accepted. It may also be provided that such installations independently remove / retract / destroy before inflating the separating element to make room for the separating element.
    As an example, FIG. 5 shows a roughly schematic vertical section through a subway tunnel or tunnel or railway tunnel. In this case, in the region of the separating element, not shown, the track bed of ballast replaced by a track bed 8 made of concrete or steel or other airtight material to form a flat support for the separator and thus together with this an airtight seal. In the area of the catenary on the ceiling of the tunnel, a recess 9 is provided, in which the catenary can be displaced by the separating element. This preferably fills the entire area 9.
    The length of the separating element is chosen as a function of the diameter and of the pressure, wherein the diameter and pressure of the tunnel, in which the separating element is installed, are predetermined.
    It is thus described according to the invention for temporary subdivision of tunnels or pipelines in which transport drive, in individual sections, a separating element which is inflatable and fills the tunnel or the pipe substantially sealingly. This can be done in separate sections especially in emergencies and especially in case of fire, a subdivision of the tunnel or the pipeline.
    While preferred embodiments of the invention are described in the present application, it should be clearly understood that the invention is not limited to these and may be practiced otherwise within the scope of the following claims.
