Temporary plugging gate and temporary plugging method of sewage pipeline

Abstract

The invention discloses a temporary plugging gate and a temporary plugging method of a sewage pipeline. The temporary plugging gate comprises a conical cylinder, a front gate plate, a connecting rod and a support frame, wherein the connecting rod is arranged in the conical cylinder through the support frame; one end of the conical cylinder is provided with a rubber pad; a bolt hole is formed in the front gate plate; a threaded hole corresponding to the bolt hole is formed in one end of the connecting rod; and the front gate plate is arranged at one end of the conical cylinder and fixed througha bolt. The temporary plugging gate is suitable for plugging construction of the sewage pipeline under a sewage well, the gate can be plugged more tightly and firmly under the action of water pressure during plugging operation, an original sewage structure is not damaged in the mounting and dismounting process, the plugging and dismounting method is simple and easy to operate, and the plugging efficiency and the plugging effect are high; and the temporary plugging gate is simple in overall structure, low in cost and easy to mount and dismount, guarantees safe plugging, and has good application prospects.

Description

Technical field [0001] The invention belongs to the field of building construction, in particular to a temporary blocking gate and a temporary blocking method of a sewage pipeline. Background technique [0002] At present, the construction capacity of my country's municipal engineering industry has grown significantly so far. The function of the city has been greatly enhanced. Municipal pipelines are the foundation of urban construction, and the relocation of municipal pipelines is the first step in urban infrastructure. [0003] The traditional sewage pipe network relocation is generally passed during the construction process: ①build new sewage pipes and abolish the original sewage pipes; ②permanently reroute the sewage pipes in conflicting parts to ensure smooth construction; ③temporarily reroute the sewage pipes until the project is completed Then restore the original sewage pipe to ensure smooth construction. [0004] During the relocation of sewage pipes, the sewage pipes need...

Problems solved by technology

Airbag sealing has great limitations: airbags are generally used for sealing small-diameter sewage pipes (φ≤1000mm); airbag sealing time should not be too long, and real-time monitoring of air pressure is necessary; airbag sealing is safe during construction The hidden danger is relatively large, and it will explode when encountering sharp objects or violent impacts; and custom airbags are expensive
