Abstract
Description
Technical Field
[0001] The invention relates to the technical field of waterproof construction of subway stations, and in particular to a waterproof structure and method for subway stations. Background Art
[0002] Subway stations are an important part of the urban rail transit system, and they undertake multiple functions such as passengers getting on and off, transferring, and evacuating. Stations are usually composed of platforms, station halls, equipment rooms, entrances and exits, air ducts, pipe corridors and other ancillary structures. Most of its structures are buried underground and need to have good waterproof performance to ensure long-term stable operation. The pipe corridor of the subway station is an underground corridor used to lay various pipelines (such as electricity, communications, water supply and drainage, ventilation, fire protection pipelines, etc.). It is usually located in the station's ancillary structures or interval tunnels and is an important part of the subway system. Since the pipe corridor is a concrete structure buried underground, it is affected by factors such as groundwater, soil water pressure, and structural settlement for a long time. Its waterproof performance is directly related to the safety and operational stability of the subway station. Therefore, in the construction of the pipe corridor, the waterproof construction of the side wall is particularly important, and reasonable waterproof materials and construction methods need to be adopted to ensure long-term leakage-free.
[0003] At present, polypropylene cloth is mostly used in the waterproof construction of the side walls of the tunnel. This material has the advantages of good durability, strong impermeability and convenient construction. It is widely used in underground structure waterproofing projects. The existing station tunnel waterproofing construction process is roughly to cut the rolled polypropylene cloth into multiple sections of appropriate sizes to meet the paving requirements of the side walls of the tunnel, and evenly apply concrete slurry on the surface of the cut polypropylene cloth as a bonding layer. The polypropylene cloth is paved on the surface of the side wall of the tunnel to make it tightly combined with the concrete base. For the joints between two adjacent sections of polypropylene cloth, concrete coating and sealing are used to enhance the waterproof performance of the joints.
[0004] As time goes by, because subway tunnels are in a humid underground environment for a long time, concrete is easily affected by long-term moisture expansion, which can easily cause tiny cracks in the joints, leading to damage to the sealing layer. The water in the external soil layer gradually penetrates into the tunnel surface and eventually invades the interior of the tunnel, causing leakage problems.
[0005] In addition, since the multiple processes in the waterproof construction process, such as cutting of polypropylene cloth, coating of adhesive materials, paving and air evacuation, mainly rely on manual operation and require the collaboration of multiple workers, the construction speed is limited by the efficiency of workers' manual operation. The overall workload is large, and manual construction is difficult to ensure the accuracy and consistency of each step. For example, the thickness of the coating adhesive layer, the degree of sealing of the splicing, etc., will vary due to the different proficiency of the workers, resulting in uneven construction quality and affecting the final waterproof effect.

The covering mechanism 10 can be provided with a plurality of and equidistantly installed on the side wall of the station corridor. The covering mechanism 10 is used to cover two adjacent polypropylene cloths paved on the side wall of the station corridor to improve the waterproof sealing performance, and at the same time automatically drain the water that penetrates into the joint of the two adjacent polypropylene cloths. The paving mechanism 20 is used to automatically pave the polypropylene cloth on the side wall of the station corridor in sequence.
[0038] See also Figure 2 , Figure 3 and Figure 4In this embodiment, the covering mechanism 10 includes a U-shaped seat 11 for installation on the side wall of the station tunnel and a U-shaped cover plate 12 for covering the U-shaped seat 11 so as to cooperate with the U-shaped seat 11. The left and right sides of the U-shaped seat 11 are fixedly connected with wing plates 13, and the left and right sides of the U-shaped cover plate 12 are fixedly connected with pressure plates 14 that cooperate with the wing plates 13. The inner cavity of the U-shaped seat 11 is provided with a drainage groove 15 with a lower opening. An introduction component 16 for introducing seepage water into the drainage groove 15 is commonly provided between the U-shaped seat 11 and the U-shaped cover plate 12.

The front end surface of the U-shaped seat 11 Two threaded holes are symmetrically opened up and down, and the front wall plate of the U-shaped cover plate 12 is symmetrically rotated up and down and connected with two studs 18 that are threadedly connected to the threaded holes. A C-shaped pressure strip 19 is fixedly connected to the rear end face of the pressure plate 14, and a C-shaped through groove is opened on the wing plate 13 for the C-shaped pressure strip 19 to pass through. The introduction component 16 includes a plurality of introduction pipes 161 that are equidistantly threadedly connected to the U-shaped seat 11 and connected to the drainage groove 15, and the introduction pipe 161 passes through the front wall plate of the U-shaped cover plate 12, and a plurality of guide holes 162 are equidistantly opened on the introduction pipe 161 in the circumferential direction, and the guide holes 162 are arranged in a plurality of rows equidistantly on the axis of the introduction pipe 161.
[0039] First, control the paving mechanism 20 to run and lay the polypropylene cloth on the side wall of the corridor in sequence. First, place multiple covering mechanisms 10 equidistantly on the side wall of the corridor, so that the two transverse sections of the U-shaped seat 11 in each covering mechanism 10 respectively contact the upper and lower end surfaces of the corridor, and then rotate the bolt 17 to make the bolt 17 contact the upper end surface of the corridor, so that the U-shaped seat 11 can be installed on the corridor, and the paved polypropylene cloth is located at the joint between two adjacent U-shaped seats 11, and the two side parts of the paved polypropylene cloth are partially attached to the wing plate 13.

The idea of "blocking is not as good as draining" is adopted, and the inlet pipe 161 and the drainage trough 15 are used to guide the water to the drainage pipe, so that the water flow can be quickly discharged from the corridor, fundamentally alleviating the pressure of accumulated water on the waterproof layer, and improving the reliability of the overall waterproof system.

Then the movable baffle plate 253 is manually lifted and moved to insert the plug 255 into the hole. At the same time, the clamping column 256 slides into the long horizontal section of the U-shaped groove 254. Then, the movable baffle plate 253 is pushed to the left to drive the clamping column 256 to slide in the U-shaped groove 254 until the clamping column 256 slides to the left and contacts the vertical section of the U-shaped groove 254.

The pulley 294 then drives the gear 298 to move and rotate on the rack 297. The gear 298 then drives the pulley 294 to rotate. The pulley 294 then drives the belt rope 295 to rotate. During the rotation of the belt rope 295, the sliding rod 296 is driven to move through the connecting block. The sliding rod 296 then drives the bearing plate 292 to move back and forth horizontally through the sliding groove. The bearing plate 292 then drives the pressing roller 293 to move back and forth on the surface of the polypropylene cloth to squeeze out the air between the polypropylene cloth and the side wall of the porch. At the same time, some excess concrete will be squeezed to both sides. The squeezed concrete moves to the seams of adjacent polypropylene cloths, and can also bond the adjacent polypropylene cloths together.
[0050] When the electric slide 24 drives the strip push plate 283 to move up to a height higher than the side wall of the pipe gallery and flush with the embedded groove, the electric slide 24 is controlled to pause, and the electric telescopic rod 282 is controlled to extend to push the strip push plate 283 to move toward the vehicle body 21. The strip push plate 283 then pushes the polypropylene cloth to be laid on the upper surface of the porch. After moving a certain distance, the strip push plate 283 pushes the polypropylene cloth to contact the cutter 284, so that the cutter 284 gradually extends into the strip groove, thereby cutting the polypropylene cloth, and at the same time controlling the pump to stop running.
[0051] Then, the lever is manually turned to reverse, and the lever then drives the pressure claw 272 to move away from the polypropylene cloth through the rotating shaft 271, controlling the electric telescopic rod 23 to extend and drive the guide rail 22 to move upward, and the guide rail 22 then drives the positioning pin 212 to be pulled out of the ground, and then the vehicle body 21 can be pushed to move horizontally along the corridor to the next paving position, and then the above paving operation process is repeated again, so that the cutting, coating, paving and emptying and compacting of the polypropylene cloth can be combined together to automatically speed up the waterproof construction speed.
[0052] In addition, the present invention also provides a subway station waterproofing method, comprising the following steps: S1, preparation before construction: cleaning the surface of the side wall of the station corridor, removing floating dust, oil stains, and loose concrete, and ensuring that the base surface is flat and has no protrusions.
[0053] S2. Waterproofing roll material laying: Then, the rolled polypropylene cloth used for waterproofing is put into the laying mechanism 20, and the laying mechanism 20 is controlled to move intermittently along the pipe gallery, and the polypropylene cloth is laid on the side wall of the pipe gallery in sequence.
[0054] S3. Then, the covering mechanism 10 is installed on the side wall of the station corridor in sequence and at equal intervals, and covers the joint between two adjacent polypropylene cloths.
[0055] S4. Quality acceptance: Use water immersion method and sampling tensile test to ensure that the waterproof membrane is intact, firmly bonded, and has no leakage risks.
