AI Technical Summary

Technical Problem

The existing tunnel lining waterproof structure is prone to the problem of unsolid welding when connecting transverse water pipes and annular water pipes, resulting in water leakage, low construction efficiency, and difficult to replace when transverse water pipes are damaged.

Method used

The joint components for easy connection are used to realize the sealed connection between the transverse water pipe and the annular water pipe through the joint components, avoiding welding, improving the construction efficiency, and making it easy to replace the transverse water pipe when it is damaged.

Benefits of technology

The sealed connection between the horizontal water pipe and the annular water pipe is achieved, which improves the waterproofing effect and construction efficiency, and simplifies the replacement process of the horizontal water pipe.
