Description

Technical Field

[0001] The utility model belongs to the technical field of bellows construction auxiliary equipment, in particular to a bellows rubber ring installation device. Background Art

[0002] During the construction of drainage pipes, there is often serious water seepage in the pipes due to improper installation of sealing facilities such as rubber rings, which causes pollution of the surrounding soil and water, roadbed settlement, road surface collapse and other hazards.

[0003] At present, construction workers generally install the rubber ring of the corrugated pipe by manually stretching the rubber ring and inserting it into the corrugated pipe, and then pulling it through the outer ribs of the corrugated pipe in turn, or prying the rubber ring through objects such as steel bars so that the rubber ring passes through the outer ribs of the corrugated pipe in turn. This method is difficult to install, time-consuming and labor-intensive, and is easy to damage the rubber ring and the corrugated pipe body. At the same time, there is a phenomenon that the installation position does not meet the requirements, resulting in unqualified sealing of the corrugated pipe and serious water seepage.
