Underground temporary plugging structure for water supply and sewerage works

Abstract

The invention discloses a temporary plugging structure, and particularly relates to an underground temporary plugging structure for water supply and sewerage works. The underground temporary plugging structure comprises a first steel ring, a first connecting plate and a second connecting plate are arranged on the first steel ring, a first bolt is connected between the first connecting plate and the second connecting plate, and a plurality of anti-skid plates are arranged on the first steel ring. During use, the first steel ring and the second steel ring are arranged at the end of a pipeline in a sleeving mode, an opening of the pipeline is abutted against a fixed baffle, then a first motor and a second motor are started to drive the first bolt and a second bolt to rotate, at the moment, the first steel ring and the second steel ring can tighten and hold the pipeline, then an air bag is inflated, and temporary plugging of the pipeline can be achieved. The underground temporary plugging structure is simple in structure and convenient to use, friction force between the device and the pipeline can be increased through the anti-skid plates, and fixing is more reliable.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage equipment, in particular to an underground temporary sealing structure for water supply and drainage engineering. Background technique [0002] Water supply and drainage pipelines refer to the system consisting of water supply, pipes and channels for collecting and discharging sewage, waste water and rainwater, and their ancillary facilities. Including main pipes, branch pipes and pipelines leading to the treatment plant, no matter they are built on the street or anywhere else, as long as they are used for drainage, they should be counted as drainage pipelines; at present, most of the pipeline ports use circular plates with the same diameter as the pipeline Welding, such a temporary blocking method, the welding time is long and the efficiency is low. At the same time, construction tools such as welding machines and electric drills are required to complete it. It is very troubleso...

Problems solved by technology

Including main pipes, branch pipes and pipelines leading to the treatment plant, no matter they are built on the street or anywhere else, as long as they are used for drainage, they should be counted as drainage pipelines; at present, most of the pipeline ports use circular plates with the same diameter as the pipeline Welding, such a temporary blocking method, the welding time is long and the efficiency is low. At the same time, construction tools such as welding machines and electric drills are required to complete it. It is very troublesome. It is not easy to remove after canceling the blocking. , and many pipelines are installed underground, the construction is difficult, therefore, it is necessary to invent an underground temporary sealing structure for water supply and drainage projects to solve the above problems
