Description

Technical Field

[0001] The utility model belongs to the technical field of building waterproof equipment, and in particular relates to a drainage structure with floor drain maintenance function. Background Art

[0002] Drainage pipe is a kind of pipe with the function of inverted filtration and water permeability. Drainage pipe has strong drainage and water seepage effect, and has no special requirements for geology and terrain. Therefore, drainage pipe is widely used in tunnels, basements and other places. Tunnels, basements and other places are prone to water leakage problems. The traditional method is to break the ground to make grooves, and then lay drainage pipes for drainage. However, ordinary groove drainage mostly uses semi-circular pipes with inverted buckles. This method is easy to enter fine sand, causing blockage inside the drainage pipe, and the dredging and maintenance of the drainage pipe is quite labor-intensive and time-consuming.

[0003] In the prior art, a Chinese patent document with publication number CN208701722U discloses a basement floor groove drainage repair structure, including a groove located at the basement crack, a drainage pipe buried in the groove, a downpipe on the side wall of the drainage pipe, and the downpipe is connected to the side wall of the drainage pipe; the downpipe extends upward to form an inspection port. The drainage repair structure is provided with an inspection port, through which the drainage pipe can be dredged, which solves the problem of clogging and dredging of the drainage pipe to a certain extent. However, in order to effectively drain water, the drainage pipe needs to be buried below the ground, and the inspection port is connected to the drainage pipe through a narrow pipe. Due to the branching of the pipeline and the small inspection port, it is difficult to use ordinary mechanical dredging equipment for dredging, and the dredging efficiency is low; in addition, the connection between the pipeline extending from the inspection port and the drainage pipe is prone to wear and leakage. Once leakage occurs, the corresponding connecting piece needs to be replaced in time. The connecting piece cannot be replaced with the help of the inspection port, and the floor needs to be chiseled open, and the secondary repair cost is high.

[0004] Therefore, in view of the problems existing in the prior art, it is urgently necessary to provide a drainage structure with floor drain maintenance. Summary of the invention

[0005] In view of the problems in the related technology, the utility model proposes a drainage structure with floor drain repair function to overcome the technical problems of low dredging efficiency and difficulty in replacing connecting parts of the existing drainage repair structure.

If a blockage occurs in the drainage pipe, the inspection pipe opening can be exposed by simply lifting out the inspection box body, and ordinary mechanical dredging equipment can be used to quickly dredge the branches at the inspection pipe opening; in addition, if the branch connecting parts of the inspection pipe opening need to be further inspected or replaced, the inspection box body is disassembled to expose the corresponding connecting parts, and the ground does not need to be excavated, which can greatly improve the inspection efficiency.

[0011] As a further improvement of the above scheme, the maintenance box body is a square structure with a hollow cavity, and a plurality of ribs are provided in the hollow cavity of the maintenance box body. The plurality of ribs are arranged between the upper and lower end surfaces of the maintenance box body in the form of mechanical support; in order to further improve the structural strength of the maintenance box body, a plurality of ribs are arranged inside the maintenance box body, which can effectively prevent the maintenance box body from being stepped on and deformed.

When the maintenance box body is placed in the pit, the annular boss and the stepped groove are engaged with each other. The pit is provided to adapt to the maintenance box body, so that the maintenance box body can be easily lifted out of the pit, which is convenient for clearing and maintenance of the drainage pipe.

[0013] As a further improvement of the above solution, a sealing layer is further provided between the annular boss and the stepped groove; the provision of the sealing layer can effectively prevent ground water from seeping into the pit through the gap between the inspection box body and the pit, thereby avoiding odor.
