Technical Field
[0001] This application relates to the field of municipal engineering supervision technology, and in particular to a permeability detection device for underground pipe corridors. Background Technology
[0002] With the acceleration of urbanization, the development and utilization of urban underground space is becoming increasingly important, and underground pipeline systems are an indispensable part of urban infrastructure. Underground integrated pipe corridors have advantages such as underground pipelines, real-time monitoring, convenient maintenance, and easy expansion, making them a construction trend for achieving sustainable urban development and an excellent carrier for urban information management.
[0003] Underground utility tunnels are mostly assembled from multiple sections, and the joints are the most prone to leakage. Due to rising groundwater levels during the rainy season, these joints pose a safety risk of sudden, large-flow, jet-like leaks under significant head differences. To ensure the safe daily operation and maintenance of the utility tunnels, effective measures must be taken for long-term monitoring of water seepage at the joints.
[0004] In order to reduce the difficulty of daily operation monitoring of underground utility tunnels, improve monitoring efficiency, and detect tunnel seepage in a timely manner, this application provides an underground utility tunnel seepage detection device. Utility Model Content

[0007] Using the above technical solution, the device moves to the joint of the underground pipe gallery on the concrete foundation below the pipe gallery. The lifting water collection component rises and touches the outside of the pipe gallery section. If water seeps out of the pipe gallery joint, the seeping water is collected into the water storage tank through the lifting water collection component, thereby detecting whether there is water seepage in the pipe gallery joint.
[0008] Optionally, the lifting water receiving assembly includes a fixed base, a lifting rod whose lower end is fixedly connected to the fixed base, and a water receiving tray fixedly connected to the upper end of the lifting rod.

[0010] The lifting rod is equipped with a water pipe that connects the drain hole to the water storage tank.
[0011] Using the above technical solution, the upper surface of the water receiving tray is a concave arc surface, which can match the outer contour of the pipe gallery section, so that the water receiving tray fits the outside of the pipe gallery, and the water collected in the water receiving tray can flow to the water storage tank through the drain hole.
[0012] Optionally, the bottom of the fixed base is fixedly connected to four fixed support columns, and the lower ends of the four fixed support columns are fixedly connected to the frame; the water storage tank is located below the fixed base and between the four fixed support columns.

[0014] Optionally, a water level measuring instrument is installed inside the water storage tank; a drain pipe is provided at the bottom of the water storage tank, and a control valve is installed on the drain pipe.
[0015] By adopting the above technical solution, a water level measuring instrument is installed in the water storage tank to monitor the amount of water seepage at the pipe gallery joint on a certain day or during a certain period of time, thereby determining the seepage situation of the pipe gallery joint; after the pipe gallery joint is inspected, the control valve is opened, and the water in the water storage tank is discharged into the bottom ditch of the concrete foundation through the drain pipe.
[0016] Optionally, a drainage groove is provided on the upper surface of the water receiving tray;
[0017] The drainage channel is connected to the drain hole of the water receiving tray.
[0018] With the above technical solution, after the water receiving tray is attached to the outside of the pipe gallery, the drainage channel and the outside of the pipe gallery form a channel, thereby guiding the seeping water to the drain hole of the water receiving tray.
[0019] Optionally, the width of the water receiving tray is greater than the width of the pipe gallery joint.
[0020] By adopting the above technical solution, the width of the water receiving tray can cover the width of the pipe gallery joint, so as to avoid the problem of incomplete collection of seepage water and affect the seepage detection of the pipe gallery joint.
[0021] Optionally, fixing plates are fixedly provided on both sides of the protective cover, and auxiliary support members are connected to the fixing plates;
[0022] The auxiliary support includes a fixed connecting rod fixedly mounted on the fixed plate at its upper end and an auxiliary wheel mounted on the lower end of the fixed connecting rod;
[0023] The auxiliary wheel rotates in the same direction as the traveling wheel; the height of the auxiliary wheel is not higher than the height of the traveling wheel.
[0024] By adopting the above technical solution, the device can be made stable during movement, preventing it from tipping over.
[0025] Optionally, the fixed connecting rod includes a straight plate and an inclined connecting plate that is fixedly connected to the straight plate.
[0026] The above technical solution facilitates the adjustment of the angle of the inclined connecting plate, achieving an auxiliary support function that conforms to the actual working environment.
[0027] Optionally, the flat plate is connected to the fixing plate by a fixing screw, and a fastening nut located on the outside of the flat plate is threaded onto the fixing screw.
[0028] The above technical solution uses fastening nuts and fixing screws for fixed installation, which facilitates the disassembly and replacement of the fixing rod.

The lifting water-collecting assembly includes a fixed base, a lifting rod, and a water-collecting tray at the upper end of the lifting rod. This device is placed on a concrete foundation beneath the underground utility tunnel. The wheels move the device to the joint of the tunnel, and the lifting water-collecting assembly rises, causing the water-collecting tray to rest against the outside of the tunnel section. If water seeps out from the joint, the seeping water is collected in the water storage tank after passing through the water-collecting tray. The seepage status of the tunnel joint is detected based on the water level signal detected by the water level meter in the water storage tank within a specific time period.

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0038] Example 1
[0039] like Figure 1 As shown, an underground pipe gallery seepage detection device includes a frame 3, a protective cover 4 fixedly installed on the frame 3, a lifting water receiving assembly installed on the frame 3 and located inside the protective cover 4, a traveling wheel 13 connected to the bottom of the frame 3, and a water storage tank 11 fixedly installed on the frame 3; the top of the protective cover 4 has a through hole 5 for the lifting water receiving assembly to pass through; the water storage tank 11 is connected to the lifting water receiving assembly.
[0040] In this embodiment, the device moves to the pipe gallery joint 2 on the concrete foundation below the underground pipe gallery. The lifting water collection component rises and touches the outside of the pipe gallery section 1. If water seeps out of the pipe gallery joint 2, the seeping water is collected into the water storage tank 11 through the lifting water collection component, thereby detecting whether there is water seepage in the pipe gallery joint 2.
[0041] In a further optimization of this embodiment, the lifting water receiving assembly includes a fixed base 7, a lifting rod 8 whose lower end is fixedly connected to the fixed base 7, and a water receiving tray 9 fixedly connected to the upper end of the lifting rod 8.
[0042] like Figure 2 As shown, a drain hole 91 is provided in the middle of the water receiving tray 9; the upper surface of the water receiving tray 9 is a concave arc-shaped surface;
[0043] The lifting rod 8 is equipped with a water pipe 10 that connects the drain hole 91 to the water storage tank 11.
[0044] In this embodiment, the upper surface of the water receiving tray 9 is a concave arc-shaped surface, which can match the outer contour of the pipe gallery section 1, so that the water receiving tray 9 fits the outer side of the pipe gallery, and the water collected in the water receiving tray 9 can flow to the water storage tank 11 through the drain hole 91.
[0045] In a further optimization of this embodiment, four fixed support columns 6 are fixedly connected to the bottom of the fixed base 7, and the lower ends of the four fixed support columns 6 are fixedly connected to the frame 3; the water storage tank 11 is located below the fixed base 7 and between the four fixed support columns 6.
[0046] In this embodiment, four fixed support columns 6 raise the fixed base 7 to a certain height, making it easier to install the water storage tank 11 below the fixed base 7. The water in the water pipe 10 does not need to be guided by other pipes. The pipe structure is convenient and simple to arrange, and can flow to the water storage tank 11 below the fixed base 7 more quickly and conveniently.
[0047] In a further optimization of this embodiment, a water level measuring instrument is installed inside the water storage tank 11; a drain pipe 12 is provided at the bottom of the water storage tank 11, and a control valve is installed on the drain pipe 12.
[0048] In this embodiment, a water level measuring instrument is installed in the water storage tank 11 to monitor the amount of water seepage at the pipe gallery joint 2 on a certain day or within a certain time period, thereby determining the seepage status of the pipe gallery joint 2 and evaluating the repair plan for the pipe gallery joint. After the pipe gallery joint 2 is inspected, the control valve is opened, and the water in the water storage tank 11 is discharged into the bottom ditch of the concrete foundation through the drain pipe 12. The device is then moved to another pipe gallery joint to inspect the seepage status. By emptying the seepage water and moving its position, the device can inspect all pipe gallery joints. Preferably, the water level measuring instrument can be equipped with a signal transmitter to transmit the water level height of the water storage tank in real time. The data is stored by a background computer and forms historical records and water level change curves, allowing technicians to accurately grasp the water leakage situation at the joints during the operation of the pipe gallery, so as to arrange timely repair work for the pipe gallery joints.
[0049] Further optimizations to this embodiment, such as Figure 3 As shown, a drainage groove 92 is provided on the upper surface of the water receiving tray 9;
[0050] The drainage channel 92 is connected to the drain hole 91 of the water receiving tray 9.
[0051] In this embodiment, after the water receiving tray 9 is attached to the outside of the pipe gallery, the drainage groove 92 forms a channel with the outside of the pipe gallery, thereby guiding the seeping water to the drain hole 91 of the water receiving tray 9.
[0052] In a further optimization of this embodiment, the width of the water receiving tray 9 is greater than the width of the pipe gallery joint 2.
[0053] In this embodiment, the width of the water receiving tray 9 can cover the width of the pipe gallery joint 2 to avoid incomplete collection of seepage water, which would affect the seepage detection of the pipe gallery joint.

[0057] The auxiliary wheel 17 rotates in the same direction as the traveling wheel 13; the height of the auxiliary wheel 17 is not higher than the height of the traveling wheel 13.
[0058] In this embodiment, the auxiliary wheel 17 has the function of auxiliary support, ensuring the stability of the device when it moves and preventing it from tipping over.
[0059] In a further optimization of this embodiment, the fixed connecting rod includes a straight plate 15 and an inclined connecting plate 16 that is fixedly connected to the straight plate 15.
[0060] In this embodiment, the angle of the inclined connecting plate 16 can be easily adjusted to achieve an auxiliary support function that conforms to the actual working environment.
[0061] In a further optimization of this embodiment, the flat plate 15 is connected to the fixing plate 14 by a fixing screw 18, and a fastening nut 19 located on the outside of the flat plate 15 is threaded onto the fixing screw 18.
[0062] In this embodiment, the fixing is achieved by fastening the nut 19 and fixing the screw 18, which facilitates the disassembly and replacement of the fixing link.
