Description

Technical Field

[0001] This invention relates to the field of tunnel seepage monitoring devices, and more particularly to a tunnel seepage monitoring device. Background Technology

[0002] During operation, the shield tunnel segment 10 is a circular pipe formed by splicing multiple tunnel segments 10. There will be joints between two tunnel segments 10. At the same time, there is a waterproof sealing gasket 20 between two tunnel segments 10, which is sandwiched in the joint between the two tunnel segments 10.

[0003] With prolonged use, the tunnel may leak water, which seeps out from the joints of the tunnel segments 10. For segment joints where the leakage is not serious or where leakage recurs after grouting repair, conventional and simple repair methods are ineffective. Furthermore, excavation, segment replacement, or large-area support maintenance require consideration of appropriate window periods. In some cases, the leakage volume is small and stable, and maintenance is not necessary. Therefore, a device for monitoring the leakage volume is needed to monitor the leakage volume in real time. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tunnel seepage monitoring device, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tunnel segment seepage monitoring device includes an arc-shaped plate with a through groove in the middle. A slider is slidably connected in the through groove. An arc-shaped baffle is fixedly connected to the outside of the slider. An installation box is fixedly connected to the arc-shaped baffle. A conical tube is rotatably connected in the installation box. A branch pipe is fixedly connected to the lower end of the arc-shaped baffle. A flexible hose is fixedly connected between the branch pipe and the conical tube. A slot is provided on the side wall of the through groove. A plug plate is inserted into the slot. A cover plate is fixedly connected to the plug plate. One end of the cover plate is fixedly connected to the plug plate. A flexible filling tube is fixedly connected to one side of the insert plate, and the flexible filling tube is filled with a plastic filler. The tapered extruded flexible filling tube is used to fill the gap between the insert plate and the segment joint; The lower end of the branch pipe is fixedly connected to an air pump or a drain pipe, and the drain pipe is equipped with a flow meter.

[0006] Preferably, the slots are respectively provided at both ends of the through slide, and multiple slots are provided at intervals at each end of the through slide. The contact surfaces of the plug plate and the cover plate with the inner wall of the through slide are respectively provided with sealing strips.

[0007] Preferably, the rotating shaft of the tapered tube is fixedly connected to a gear, the rotating shaft of the tapered tube is provided with a torsion spring, the mounting box is slidably connected to a push rod, the push rod meshes with the gear through the tooth groove in the middle, and the two ends of the push rod extend out of the mounting box and are limited by the plug-in plate.

[0008] Preferably, the flexible filling tube has an outer layer, the layer is filled with gel liquid, the insert plate has a groove, the groove has sharp teeth, and the sharp teeth are used to pierce the layer.

[0009] Preferably, the tapered tube is inclined relative to the flexible filling tube, and the tapered tube presses against the outer end of the flexible filling tube.

[0010] Preferably, a mounting frame is fixedly connected to the upper end of the arc-shaped baffle, the mounting frame is hinged to an electric telescopic rod, and a pin is provided between the telescopic end of the electric telescopic rod and the arc-shaped baffle.

[0011] Preferably, the contact surface between the arc-shaped plate and the tunnel segment is provided with a hot-melt waterproof membrane.

[0012] The advantages of this invention are as follows: The tunnel seepage monitoring device provided by this invention addresses joint leakage in tunnel segments. Residue remaining in the joint after enlargement can clog the drainage pipes for concentrated seepage. An arc-shaped plate is fixed to the leakage area, and a through-slide guides the arc-shaped plate's sliding. The arc-shaped plate slides back and forth along the through-slide, while a cone-shaped tube moves at an angle and blows out high-pressure air to remove impurities from the joint. When the arc-shaped plate moves to the other end of the through-slide, the cone-shaped tube rotates and reverses direction, further cleaning the remaining debris from another direction, ensuring thorough cleaning. After repeated cleaning (controlling the movement distance to avoid squeezing the flexible filling tube), the arc-shaped plate moves to its maximum stroke, allowing the cone-shaped tube to squeeze the flexible filling tube. The flexible filling tube deforms and fills the gap, facilitating the formation of a closed area for concentrated drainage and monitoring of seepage. This invention provides guidance for cleaning the joint, allows changing direction to discharge debris or dust from opposite gaps, squeezes and deforms the flexible filling tube for sealing, and ultimately can be used for centralized drainage, among other conveniences.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0015] Example 1 like Figures 1 to 5 As shown, the present invention provides a tunnel segment seepage monitoring device, including an arc plate 1. The arc plate 1 is designed to fit the arc of the tunnel segment. A hot-melt waterproof membrane is provided on the contact surface between the arc plate 1 and the tunnel segment and is hot-melt bonded to the tunnel segment 10. A through groove 2 is provided in the middle of the arc plate 1. A slider is slidably connected in the through groove 2. An arc baffle 3 is fixedly connected to the outside of the slider. The arc baffle 3 can slide back and forth on the outer arc surface of the arc plate 1 by hand, or a mounting frame 31 is fixedly connected to the upper end of the arc baffle 3 by bolts. An electric telescopic rod 32 is hinged to the mounting frame 31. A pin 33 is provided between the telescopic end of the electric telescopic rod 32 and the arc baffle 3. The electric telescopic rod 32 can be disassembled after use.

[0016] The arc-shaped baffle 3 always closes the through groove 2 when sliding. The arc-shaped baffle 3 is fixedly connected to the mounting box 4. The tapered tube 5 is rotatably connected inside the mounting box 4. The lower end of the arc-shaped baffle 3 is fixedly connected to the branch pipe 6. The branch pipe 6 and the tapered tube 5 are fixedly connected to the hose 7. The side wall of the through groove 2 is provided with a slot 8. A plug plate 81 is inserted into the slot 8. The plug plate 81 is fixedly connected to the cover plate 82. One end of the cover plate 82 is fixedly connected to the plug plate 83. A flexible filling tube 9 is fixedly connected to one side of the insert plate 83. The flexible filling tube 9 is filled with a plastic filler, which is a structural adhesive, cement mortar with added early strength agent, or other colloid that can deform and harden to fill. The plastic filler is initially soft and is shaped by extrusion. It hardens within a certain time to form a filling and sealing. The tapered tube 5 is used to extrude the flexible filling tube 9 to fill the gap between the insert plate 83 and the segment joint; The lower end of branch pipe 6 is fixedly connected to an air pump or a drainage pipe. The drainage pipe is equipped with a flow meter 30, and the lower end of the drainage pipe is placed into the drainage ditch of the tunnel.

[0017] The plug plate 81, cover plate 82, plug plate 83 and deformed flexible filling pipe 9 surround the leakage point, so that the seeping water is concentrated and discharged through the branch pipe 6 and recorded by the flow meter 30.

[0018] This invention addresses joint leakage in tunnel segments 10. Residual debris remaining in the joint after enlargement can clog the drainage pipes for concentrated seepage. An arc-shaped plate 1 is fixed to the leakage area, and a through-groove 2 guides the sliding of an arc-shaped baffle 3. The arc-shaped baffle 3 slides back and forth along the through-groove 2. A cone-shaped tube 5 moves at an angle and blows out high-pressure air to remove impurities from the joint. When the arc-shaped baffle 3 moves to the other end of the through-groove 2, the cone-shaped tube 5 rotates and changes direction, allowing debris that could not be blown away in the previous direction and residual debris to be further cleared in the other direction. The process ensures thorough cleaning of debris. After repeated cleaning (controlling the movement distance to prevent squeezing the flexible filling tube 9), the arc-shaped baffle 3 moves to its maximum stroke, allowing the cone tube 5 to squeeze the flexible filling tube 9. The flexible filling tube 9 deforms and fills the gap 40, facilitating the formation of a closed area for concentrated drainage and monitoring. This invention provides guidance for cleaning gaps, allows changing directions to discharge debris or dust from the opposite gap 40, squeezes and deforms the flexible filling tube 9 for sealing, and ultimately can be used for centralized drainage, among other conveniences.

[0019] Example 2 like Figures 1 to 5 As shown, slots 8 are respectively provided at both ends of the through slide 2, and multiple slots are provided at intervals at each end of the through slide 2. Sealing strips are respectively provided on the contact surfaces of the plug plate 81 and the cover plate 82 with the inner wall of the through slide 2. The water baffle formed by the two sets of plug plates 81, cover plate 82 and plug plate 83 controls the spacing according to the leakage range. The spacing is controlled by inserting the plug plate 81 into the slots 8 at different positions.

[0020] Example 3 like Figures 1 to 5 As shown, the shaft of the tapered tube 5 is fixedly connected to the gear 51, the shaft of the tapered tube 5 is provided with a torsion spring, the mounting box 4 is slidably connected to the push rod 52, the push rod 52 meshes with the gear 51 through the tooth groove in the middle, and the two ends of the push rod 52 extend out of the mounting box 4 and are limited by the plug plate 81.

[0021] In this embodiment, as the arc-shaped baffle 3 slides from one end of the through groove 2 to the other end, after one end of the push rod 52 abuts against the corresponding plug plate 81, the push rod 52 slides relative to the mounting box 4. The push rod 52 pushes the gear 51 to rotate, causing the tapered tube 5 to change direction. The inclined direction can be changed and the joint can be cleaned with high-pressure air blowing without the need to add a control device.

[0022] Example 4 like Figures 1 to 5 As shown, the flexible filling tube 9 has an interlayer 91 on its outer wall, and gel liquid is injected into the interlayer 91. The insert plate 83 has a groove 92, and sharp teeth 93 are provided in the groove 92. The sharp teeth 93 are used to pierce the interlayer 91. The cone tube 5 is inclined relative to the flexible filling tube 9, and the cone tube 5 squeezes the outer end of the flexible filling tube 9.

[0023] The flexible filling tube 9 is a rubber film sleeve, which is easy to deform. The plastic filling material inside the flexible filling tube 9 has an early strength agent added, so that it can maintain the sealing shape in time after extrusion and plastic filling. The tapered tube 5 extrudes the outer end of the flexible filling tube 9, so that the plastic filling material inside the flexible filling tube 9 moves to the gap 40. This forms the effect of the sealing structure of the present invention, which gathers inside the joint and seals the gap of the external sealing plate 83, making it easy to seal tightly. Furthermore, after the flexible filling tube 9 deforms and the interlayer 91 contacts the sharp tooth 93 and breaks, the gel liquid overflows and further seals the gap between the flexible filling tube 9 after deformation and the joint, thereby forming a closed water collection cavity between the water baffles formed by the two sets of plug plates 81, cover plate 82 and plug plate 83, and finally the drainage is monitored through the cone tube 5.

[0024] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
