Description

Technical Field

[0001] The invention relates to the field of corrugated pipe installation, and more specifically to a corrugated pipe installation device and an installation method thereof for culvert construction. Background Art

[0002] A culvert is a drainage channel built under the roadbed and below the road surface during highway construction in order to allow the highway to pass through the canal smoothly without hindering traffic. This structure allows water to flow under the highway.

[0003] Culvert construction requires the laying of pipes first. Corrugated pipes, as a water-passing pipe, are not easily damaged and can adapt to the expansion and contraction caused by temperature changes.

[0004] The traditional installation of corrugated pipes on the market adopts the manual docking method. Workers lift and dock the two corrugated pipes, and then seal the connection between the two corrugated pipes by burning heat shrink rings. When the weight of the corrugated pipe is large, it is not easy for workers to lift the corrugated pipe, and it is difficult to dock the two corrugated pipes. In addition, the temperature and time of the heat shrink ring burned by the flame are difficult to control, resulting in poor sealing effect at the connection of the corrugated pipe.
