Description

Technical Field

[0001] The utility model relates to the technical field of pipeline maintenance equipment, in particular to a pipeline maintenance device for water supply and drainage on a subway platform. Background Technique

[0002] Water supply and drainage pipelines refer to the system composed of pipes and their ancillary facilities for collecting and discharging sewage, wastewater and rainwater, including main pipes, branch pipes and pipes leading to treatment plants. No matter they are built on the street or other places, as long as they play a role in drainage, they can be called water supply and drainage pipelines. To ensure the drainage performance in the subway tunnel, a large number of water supply and drainage pipelines are set at the subway platform. Due to the large passenger flow of the subway, when the pipeline breaks, it is generally necessary to block the crack first to ensure the normal use of the pipeline, and then replace and maintain it when the subway stops operating or the passenger flow is small. However, the existing pipeline maintenance devices for water supply and drainage generally adopt a fixed structure, which is more cumbersome to install and has poor practicability. Content of the Utility Model

[0003] The purpose of the utility model is to provide a pipeline maintenance device for water supply and drainage on a subway platform to solve the problems raised in the above background technique.

[0026] Embodiment 1

[0027] As Figures 1-5 shown, in this embodiment, the fixing mechanism 200 includes two semi-circular shells 210 and two fixing bolts 230. The two semi-circular shells 210 face each other. At both ends of the outer side wall of the semi-circular shell 210, fixing plates 220 are fixedly connected. And a threaded hole 221 is opened at the middle position of the fixing plate 220.
