Description

Technical Field

[0001] The present invention relates to the technical field of integrated pipe galleries, and more specifically, to an anti-seepage protection structure for a tunnel integrated pipe gallery. Background Art

[0002] An integrated pipe gallery refers to a tunnel space built underground in a city for centralized laying of municipal pipelines such as electricity, communication, radio and television, water supply, drainage, heat, and gas. It is an underground infrastructure that integrates multiple utility pipelines. Since the tunnel integrated pipe gallery is located underground, protection measures to prevent groundwater from seeping into the tunnel integrated pipe gallery are extremely crucial; However, in the existing anti-seepage protection structure for tunnel integrated pipe galleries, foaming glue is filled at the top of the tunnel integrated pipe gallery to enhance the anti-seepage protection ability. During the process of preventing seepage in long-term contact with groundwater, the foaming glue is prone to aging, resulting in a continuous decline in the anti-seepage ability of the foaming glue, reducing the anti-seepage protection of the tunnel integrated pipe gallery. At the same time, when water seeps through the top of the tunnel integrated pipe gallery, it cannot be observed in a timely manner, which is not conducive to making timely seepage treatment work after seepage. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical purpose is: an anti-seepage protection structure for a tunnel integrated pipe gallery, the structure of which includes a pipe gallery main body, a strengthening column, and an anti-seepage mechanism. The strengthening column is provided on the inner wall of the pipe gallery main body. The protection mechanism provided on the anti-seepage mechanism is installed on the top of the pipe gallery main body, and the inclined struts provided on the anti-seepage mechanism are inclined to support the bottom of the protection mechanism and the outer surface of the pipe gallery main body. A diversion mechanism is installed inside the top frame provided on the protection mechanism; The protection mechanism is internally filled with a foaming glue layer. A support plate is provided at the bottom of the foaming glue layer, and a filling port penetrates through the support plate. The foaming glue layer is filled between the upper part of the support plate and the diversion mechanism through the filling port. A sleeve and a sealing plate are also provided at the bottom of the support plate; The upper end of the sealing plate is provided with an insertion connecting pipe, and a water stop strip is embedded inside the insertion connecting pipe. The top of the insertion connecting pipe is inserted and installed inside the sleeve, and the water stop strip is blocked inside the sleeve and the filling port.

[0004] As a further improvement of the present invention, a support mechanism is also provided on the protection mechanism, and the support mechanism is composed of an inspection opening, an upper bearing plate, a cylinder rod, a hinge block, and a moving buckle plate. The inspection opening is provided at the bottom of the top frame, and the lower end of the inspection opening is axially connected to the lower end of the cylinder rod. The output end of the cylinder rod drives the moving buckle plate to move inside the descending groove provided on the upper bearing plate under the hinge of the hinge block, so that the moving buckle plate is buckled and combined with the fixed buckle plate provided at the bottom of the upper bearing plate, firmly pressing the upper bearing plate against the upper end inside the inspection opening to provide a supporting force for the bottom of the sealing plate.

[0005] As a further improvement of the present invention, the diversion mechanism is composed of a maintenance top plate, a diversion groove and a connecting rotating shaft. The groundwater is diverted through the diversion groove embedded in the top of the maintenance top plate, and the maintenance top plate can be turned upwards inside the top frame through the connecting rotating shaft arranged at the outer end of the maintenance top plate. The maintenance top plates on both sides are symmetrically installed left and right inside the top frame to form a structure for diverting to both sides.

[0006] As a further improvement of the present invention, the anti-seepage mechanism is further provided with a collection mechanism. The collection mechanism is composed of a water inlet, a diversion pipe, a collection pipe and a monitoring mechanism. The water inlet is embedded inside the top frame, and the groundwater is diverted into the diversion pipe installed inside the inclined strut through the water inlet. The lower ends of multiple diversion pipes are connected through the collection pipe to converge the groundwater into the monitoring mechanism. There is one diversion pipe inside each inclined strut, and a water inlet is correspondingly arranged at the top of each diversion pipe.

[0007] As a further improvement of the present invention, the monitoring mechanism includes a water level monitor, a water collection tank, a water level sensor, a water inlet and a sealing cover. The lower end of the water level monitor is connected with a water level sensor, and the water level sensor penetrates through the sealing cover and enters the water collection tank to monitor the water level of the groundwater collected inside the water collection tank. A water inlet is arranged at the rear end of the water collection tank and is connected to the collection pipe in a through manner.

[0008] As a further improvement of the present invention, an extended fixing plate, a linkage rod, a traction shaft, a plugging rod and a fastening plate are further arranged on the outer side of the water collection tank. There are two linkage rods, and the upper end of the extended fixing plate is axially connected to the lower linkage rod. The two linkage rods are connected through the traction shaft, and the upper linkage rod is axially connected to the bottom of the outer side of the fastening plate. A plugging rod is also arranged at the inner end of the traction shaft, and the plugging rod is inserted and installed inside the outer side of the fastening plate. By pushing the traction shaft inwards, the two linkage rods are interlocked to adjust the lifting of the fastening plate, and the plugging rod inside the traction shaft is inserted into the outer side of the fastening plate.

[0009] The beneficial effects of the present invention are as follows: 1. When the foaming adhesive layer ages and seeps water, blocked by the supporting plate, the seepage water flows down through the filling port and contacts the water stop strip. The water stop strip swells when encountering water, improving the effect of sealing the filling port, thereby enhancing the anti-seepage ability of the top of the pipe gallery main body; 2. By contracting the cylinder rod, the moving buckle plate is driven to separate from the fixed buckle plate at the bottom of the upper bearing plate. Then, the cylinder rod is rotated downwards at the bottom of the maintenance opening. At this time, the descending groove on the upper bearing plate can pass through the position of the cylinder rod, ensuring that the upper bearing plate moves out of the maintenance opening, so as to facilitate removing the upper sealing plate from the maintenance opening to check or replace the service performance of the water stop strip; 3. The water level inside the water collecting tank is monitored in real time through the water level sensor inside the water collecting tank. Once the water level inside the water collecting tank is too high, it means that there is too much groundwater on the top frame of the main body of the pipe gallery, and there is a risk of water seepage on the top of the main body of the pipe gallery. At this time, the water level monitor will issue an alarm to remind the staff to make preparations for anti-seepage treatment. Brief Description of the Drawings

Detailed Embodiment

[0019] The present invention will be further described below in conjunction with the accompanying drawings: Example 1:

[0020] As shown in the attached Figure 1 to the attached Figure 6 figure: An anti-seepage protection structure for an integrated tunnel utility tunnel of the present invention, the structure comprising a utility tunnel main body 1, a strengthening column 2, and an anti-seepage mechanism 3. The strengthening column 2 is provided on the inner wall of the utility tunnel main body 1. A protection mechanism 32 provided on the anti-seepage mechanism 3 is installed on the top of the utility tunnel main body 1. And an inclined support column 31 provided on the anti-seepage mechanism 3 is inclined to support the bottom of the protection mechanism 32 and the outer surface of the utility tunnel main body 1. A diversion mechanism 33 is installed inside a top frame 321 provided on the protection mechanism 32; A foaming glue layer 322 is filled inside the protection mechanism 32. A support plate 3221 is provided at the bottom of the foaming glue layer 322. And a filling port 3222 penetrates through the support plate 3221. The foaming glue layer 322 is filled between the upper side of the support plate 3221 and the diversion mechanism 33 through the filling port 3222. A sleeve 3223 and a sealing plate 3224 are further provided at the bottom of the support plate 3221; An insertion pipe 2241 is provided at the upper end of the sealing plate 2241. And a water stop strip 2242 is embedded inside the insertion pipe 2241. The top of the insertion pipe 2241 is inserted and installed inside the sleeve 3223. The water stop strip 2242 is sealed inside the sleeve 3223 and the filling port 3222; A support mechanism 323 is further provided on the protection mechanism 32. And the support mechanism 323 is composed of an inspection opening 3231, an upper bearing plate 3232, a cylinder rod 3233, a hinge block 3234, and a moving buckle plate 3235. The inspection opening 3231 is provided at the bottom of the top frame 321. And the lower end of the inspection opening 3231 is axially connected to the lower end of the cylinder rod 3233. The output end of the cylinder rod 3233 drives the moving buckle plate 3235 to move inside a descending groove 2322 provided on the upper bearing plate 3232 under the hinge of the hinge block 3234. So that the moving buckle plate 3235 is buckled and combined with a fixed buckle plate 2321 provided at the bottom of the upper bearing plate 3232. The upper bearing plate 3232 is firmly pressed against the upper end inside the inspection opening 3231 to provide a supporting force for the bottom of the sealing plate 3224; The diversion mechanism 33 is composed of an inspection top plate 331, a diversion groove 332, and a connecting rotating shaft 333. The groundwater is diverted through the diversion groove 332 embedded at the top of the inspection top plate 331. And the inspection top plate 331 can be turned upwards inside the top frame 321 through the connecting rotating shaft 333 provided at the outer end of the inspection top plate 331;In the present invention, a seepage prevention mechanism 3 is established in the pipe gallery main body 1. A plurality of inclined struts 31 provided on both sides tilt and support the protection mechanism 32 at the extended end of the top edge of the pipe gallery main body 1, providing a stable supporting force for the protection mechanism 32 on the top of the pipe gallery main body 1. When the seepage prevention protection structure is initially established, the support mechanism 323 has not yet supported the sealing plate 3224 at the inner lower end of the top frame 321. By filling the foaming glue layer 322 into the filling port 3222 of the support plate 3221, the foaming glue layer 322 fills the space between the diversion mechanism 33 and the support plate 3221. Cooperating with the diversion grooves 332 on the maintenance top plate 331, the infiltrated groundwater is diverted to both sides, performing seepage prevention protection work on the top of the pipe gallery main body 1. After filling, the sealing plate 3224 is installed at the bottom of the support plate 3221. At this time, the insertion pipe 2241 on the sealing plate 3224 is inserted into the sleeve 3223 at the bottom of the support plate 3221, and the water stop strip 2242 is abutted against the bottom of the filling port 3222. Then, the upper bearing plate 3232 is pushed into the upper end of the maintenance port 3231. The moving clamping plate 3235 is pushed by the cylinder rod 3233, so that the moving clamping plate 3235 is clamped at the bottom of the fixed clamping plate 2321 of the upper bearing plate 3232, providing a supporting force for the sealing plate 3224. Once a large amount of water seeps through the diversion mechanism 33, the groundwater flows downward through the foaming glue layer 322 and contacts the water stop strip 2242 inside the filling port 3222. Through the water stop strip 2242 swelling when encountering water, the filling port 3222 is blocked, improving the ability to prevent water seepage at the top of the pipe gallery main body 1. On the contrary, by contracting the cylinder rod 3233, the moving clamping plate 3235 is driven to separate from the fixed clamping plate 2321. The descending groove 2322 on the upper bearing plate 3232 can pass through the position of the cylinder rod 3233, ensuring that the upper bearing plate 3232 moves down out of the maintenance port 3231, and the upper sealing plate 3224 is removed from the maintenance port 3231 to check or replace the service performance of the water stop strip 2242.;

[0021] In a preferred technical solution, the filling port 3222 has a cavity structure with a wider upper end and a narrower lower end, and the size of the support plate 3221 is set according to the size of the top of the pipe gallery main body 1. Thus, a plurality of filling ports 3222 are distributed on the support plate 3221. When the foaming glue layer 322 ages and water seeps through, blocked by the support plate 3221, the seepage flows downward through the filling port 3222 and contacts the water stop strip 2242. Through the water stop strip 2242 swelling when encountering water, the effect of blocking the filling port 3222 is improved, thereby enhancing the ability to prevent water seepage at the top of the pipe gallery main body 1; A preferred technical solution is that the size of the upper bearing plate 3232 is slightly smaller than the internal space of the inspection opening 3231, ensuring that the upper bearing plate 3232 can move inside the inspection opening 3231. And the length of the upper bearing plate 3232 is set according to the length of the support plate 3221, and the number of the cylinder rods 3233 is set according to the length of the upper bearing plate 3232. The number of the descending grooves 2322 provided on the upper bearing plate 3232 corresponds to the number of the cylinder rods 3233 provided. When disassembling, by the contraction of the cylinder rods 3233, the moving clamping plate 3235 is driven to separate from the fixed clamping plate 2321 at the bottom of the upper bearing plate 3232. Then, the cylinder rods 3233 are rotated downward at the bottom of the inspection opening 3231. At this time, the descending grooves 2322 on the upper bearing plate 3232 can pass through the positions of the cylinder rods 3233, ensuring that the upper bearing plate 3232 moves downward out of the inside of the inspection opening 3231, so as to facilitate removing the upper sealing plate 3224 from the inspection opening 3231 to check or replace the service performance of the water stop strip 2242; A preferred technical solution is that there are two inspection top plates 331, which are symmetrically installed inside the top frame 321 from left to right, forming a structure for guiding water flow to both sides, facilitating guiding the infiltrated groundwater to both sides, accelerating the dispersion of the groundwater from the top of the pipe gallery main body 1, and avoiding the accumulation of groundwater at the top of the pipe gallery main body 1 and increasing the possibility of water seepage. And through the upward flipping of the inspection top plate 331, it is convenient to remove the overall aged foaming glue layer 322, so as to replace the new foaming glue layer 322.

[0022] Embodiment 2: On the basis of Embodiment 1, as shown in the attached Figure 3 and attached Figure 7 and the attached drawings: The anti-seepage mechanism 3 is also provided with a collection mechanism 34. The collection mechanism 34 is composed of a water inlet 341, a diversion pipe 342, a collection pipe 343 and a monitoring mechanism 344. The water inlet 341 is embedded inside the top frame 321. The groundwater is diverted into the diversion pipe 342 installed inside the inclined strut 31 through the water inlet 341. The lower ends of multiple diversion pipes 342 are connected by the collection pipe 343 to converge the groundwater into the monitoring mechanism 344. The monitoring mechanism 344 includes a water level monitor 3441, a water collection tank 3442, a water level sensor 3443, a water inlet 3444 and a sealing cover 3445. The lower end of the water level monitor 3441 is connected with the water level sensor 3443. The water level sensor 3443 penetrates through the sealing cover 3445 and enters the water collection tank 3442 to monitor the water level of the groundwater collected inside the water collection tank 3442. An water inlet 3444 is arranged at the rear end of the water collection tank 3442 and is connected to the collection pipe 343 in a through manner. An extended fixing plate 4421, a linkage rod 4422, a traction shaft 4423, a plugging rod 4424 and a fastening plate 4425 are also arranged outside the water collection tank 3442. The upper end of the extended fixing plate 4421 is axially connected to the lower linkage rod 4422. The two linkage rods 4422 are connected by the traction shaft 4423. The upper linkage rod 4422 is axially connected to the bottom outside of the fastening plate 4425. A plugging rod 4424 is also arranged at the inner end of the traction shaft 4423. The plugging rod 4424 is plugged and installed inside the outside of the fastening plate 4425. In the present invention, the groundwater inside the top frame 321 is diverted to both sides through the diversion groove 332 and enters the water inlets 341 on both sides. It continues to flow downward through the diversion pipe 342. Under the convergence of the collection pipe 343, it flows into the water collection tank 3442 through the water inlet 3444 for collection. At this time, the water level sensor 3443 inside the water collection tank 3442 monitors the water level inside the water collection tank 3442 in real time. The monitored data is displayed through the water level monitor 3441. And a fastening plate 4425 is arranged outside the water collection tank 3442. The fastening plate 442 tightly fastens at the edge between the outside of the water collection tank 3442 and the sealing cover 3445 to prevent the moisture in the air inside the pipe gallery main body 1 from entering the water collection tank 3442 through the gap between the water collection tank 3442 and the sealing cover 3445. Once the water level inside the water collection tank 3442 is too high, it means that there is too much groundwater on the top frame 321 at the top of the pipe gallery main body 1, and there is a risk of water seepage at the top of the pipe gallery main body 1. At this time, the water level monitor 3441 will issue an alarm to remind the staff to make preparations for anti-seepage treatment.

[0023] A preferred technical solution is that a diversion pipe 342 is provided inside each of the plurality of inclined struts 31, and a water inlet 341 is correspondingly arranged at the top of each diversion pipe 342. Through the cooperation of the plurality of water inlets 341 and the diversion pipes 342, the underground water permeating onto the top frame 321 can be quickly dispersed and discharged downward, avoiding water seepage at the top of the pipe gallery main body 1 caused by the long-term stay of underground water on the top frame 321. A preferred technical solution is that there are two linkage rods 4422, which are installed vertically. By pushing the traction shaft 4423 inward, the two linkage rods 4422 are interlocked to adjust the lifting of the fastening plate 4425. And the insertion rod 4424 inside the traction shaft 4423 is inserted into the inside of the outer side of the fastening plate 4425 to improve the positioning after the movement of the traction shaft 4423, so that the fastening plate 4425 can be tightly fastened at the edge between the outer side of the water collection tank 3442 and the sealing cover 3445, avoiding the moisture in the air inside the pipe gallery main body 1 from entering the inside of the water collection tank 3442 through the gap between the water collection tank 3442 and the sealing cover 3445, resulting in errors in the groundwater level monitoring by the water level sensor 3443.

[0024] Any technical solution that uses the technical solution of the present invention or is designed by those skilled in the art under the inspiration of the technical solution of the present invention to achieve the above technical effects falls within the protection scope of the present invention.
