AI Technical Summary

Technical Problem

The existing tunnel lining deformation joints have poor waterproofing effect under normal fault tension deformation, which can easily lead to water leakage, and it is difficult and costly to repair the fault after staggered faults.

Method used

A self-contained waterproof joint through the normal fault tunnel is designed, including a female lock, a male lock and a lock filling structure. Through the cooperation of the deformation absorption layer and the secondary lining layer, the lock structure is used to convert the tension when the fault is staggered. The pull deformation is compressive deformation, which enhances the waterproof effect and is repaired by simple filling after the fault is staggered.

Benefits of technology

When the normal fault is staggered, good waterproofing effect is achieved, and the repair is difficult and costly after the fault is staggered, ensuring the rapid recovery function of the tunnel.
