Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a rainwater and sewage pipeline repair tool. Background Art

[0002] Stormwater pipes are an indispensable part of modern urban infrastructure. They are related to the normal operation of the urban drainage system and the cleanliness of the urban environment. The main function of stormwater pipes is to collect rainwater and sewage separately. When the pipes are used for a long time, they are prone to corrosion and gaps, so pipe repair tools are needed to repair them.

[0003] After searching, the patent number is CN220013936U, and the name is a utility model of a rainwater and sewage pipe repair tool, including a cover plate. Through research and analysis, it is found that although the main strap and the auxiliary strap can be quickly tightened by rotating the rotating shaft, the whole operation process saves time and effort, thereby improving the efficiency of the pipeline repair work. However, there are still the following disadvantages to a certain extent.

[0004] For example, because it does not have a good sealing effect when in use, the sealing gasket cannot seal the gap tightly when sealing the pipe surface, which is prone to water leakage, reducing the sealing repair effect, and it does not have the function of positioning installation, so it is not convenient for the staff to fix it on the pipe. It is easy to shake when fixing, affecting the installation and fixation of the staff. In order to solve the above technical problems, we have designed a rainwater and sewage pipe repair tool.
