Description

Technical Field

[0001] The invention relates to the technical field of construction of pre-buried leak-proof structures for subway station main bodies, and in particular to a pre-buried leak-proof structure and method suitable for subway station main bodies. Background Art

[0002] During the construction and operation of subway stations, structural leakage is a relatively common problem. Since subway stations are usually located below the groundwater level and are subject to the pressure of groundwater, and at the same time have to withstand the influence of multiple factors such as stratum deformation and train vibration, the wall structure of the station is prone to defects such as cracks and pores, which cause the leaked groundwater to enter the cracks in the wall structure. Leakage will cause damage to facilities and equipment failure in the station, and cause the interior decoration and decorative materials to mold. Mechanical pressure injection of epoxy resin slurry is used for sealing, but it is found in use that most of them do not have the function of actively preventing clogging through grouting pipes. During the grouting process, the particles in the epoxy resin slurry will precipitate and adhere, and the slurry cannot be stirred or circulated in time, which will gradually solidify the epoxy resin slurry and block the grouting pipes, which is not conducive to long-term use, affecting the grouting efficiency and quality, and is not conducive to the diversion and discharge of leaking groundwater to prevent the leaking groundwater from leaking into other walls for a long time.

[0003] For example, the prior art application number CN213653549U provides a pre-buried plugging structure suitable for the main body of a subway station in a water-rich stratum, which includes: a main body side wall, a plurality of grouting pipes are arranged at horizontal intervals on the main body side wall, the grouting pipe is detachably provided with a rubber plug at the inner end of the main body side wall, the grouting pipe is provided with a connecting pipe fitting 1 at the outer end of the main body side wall, and the connecting pipe fitting 1 is detachably provided with a steel pipe plug. Compared with the prior art, the utility model pre-buries a plugging structure when the main structure of the subway station is cast. It is simple to operate, and the drilling process is reduced in the later plugging grouting. After grouting through the plugging structure, the affected range is large, the plugging effect is good, and the damage to the appearance quality of the main structure is reduced. The utility model has a simple structure, significantly improves construction efficiency, and reduces labor input and material costs;

[0004] Through actual usage, it is known that the above-mentioned existing technology mainly reduces the drilling process by using steel pipe plugs and connecting pipe fittings, and has a good sealing effect; but it is found during use that it does not have the function of actively preventing the grouting pipe from being blocked. During the grouting process, the particles in the epoxy resin slurry will precipitate and adhere, and the slurry cannot be stirred or circulated in time, which will gradually cause the epoxy resin slurry to solidify and block the grouting pipe, which is not conducive to long-term use, affecting the grouting efficiency and quality, and is not conducive to the diversion and discharge of leaked groundwater, avoiding the long-term existence of leaked groundwater in leaking other walls. For this reason, we have improved the above-mentioned existing technology based on actual usage. Summary of the Invention

Then, the operator starts the existing grouting machine body 2 and connects the delivery pipe 3 through the execution end of one side wall to deliver the epoxy resin slurry to the threaded sleeve 51 that is threadedly connected to the delivery pipe 3 and adjacent to the stop valve 4 at one end, and the side wall of the threaded sleeve 51 is provided with an inner rotating grouting pipe 58. The stop valve 4 is installed on the side wall of one end of the delivery pipe 3 and is triggered by the PLC controller to perform appropriate flow control and open. The operator controls the flow through the PLC. The device transmits an electrical signal to trigger the execution end of the motor 532 to drive a round rod 533 provided at one end. The execution end of the motor 532 is connected to the side wall of the motor housing 53 and the outer wall of the motor housing 53 to support the rotation. The rotation of the round rod 533 drives the outer wall embedded with a first gear 534 to rotate. The rotation of the first gear 534 drives the inner rotating grouting pipe 58 to rotate. The outer wall of one end of the inner rotating grouting pipe 58 is embedded with the first gear 534 and the second gear 581 that meshes with the inner rotating grouting pipe 58 is meshed with the inner rotating grouting pipe 58.

The outer ring side walls of the two sets of rotating bearings 57 are provided with the inner cavity side walls of the outer sleeve 55 for supporting the rotation. The rotation of the inner rotating grouting pipe 58 drives the spiral blades 582 provided on the inner cavity side walls to spirally and evenly transport the epoxy resin slurry, which is convenient for the particles in the epoxy resin slurry to precipitate and adhere during the grouting process, and the slurry can be stirred or circulated in time, which will gradually solidify the epoxy resin slurry and block the grouting pipe, which is beneficial for long-term plugging use.

[0054] When diverting and discharging the leaking groundwater, the water leaking from the bottom of the seepage wall body 6 enters the metal filter 5652 provided on the inner wall of the circular fixed filter plate shell 565 through gravity to filter the seepage water, so that the water enters the diversion pipe 562 and then enters the inner cavity of the connected square water storage tank 561. The PLC controller transmits an electric signal to trigger the circulation pump 564 installed on one end side wall of the water pipe 563 to extract and discharge the water from the inner cavity of the square water storage tank 561, so as to avoid the water affecting the sealing effect of the epoxy resin mortar liquid, and is conducive to diverting and discharging the leaking groundwater at the same time, so as to avoid the long-term existence of the leaking groundwater in other walls, and manually rotate the circular fixed filter plate shell 565 includes two groups of fixed screws 5651 with the same structure symmetrically arranged on both sides of the outer wall, which are detached from the threaded groove opened on the outer wall at one end of the top of the guide pipe 562 to disassemble the circular fixed filter plate shell 565, so as to facilitate the replacement of the metal filter screen 5652 provided on the inner wall of the circular fixed filter plate shell 565, and the waterproof rubber coating 541 is provided on both sides of the waterproof plate 54. The waterproof performance facilitates water to leak out of the outside of the seepage wall body 6. Through the above operation, it is convenient to actively prevent the grouting pipe from being blocked and to divert and discharge the leaking groundwater at the same time, so as to avoid the leaked groundwater from leaking into other walls for a long time. It has a simple structure and is easy to operate.
