This structure enhances the tightness and improves the sealing performance. Anti-seepage effect.

After the pipe 1 and the pipe 2 are connected, place the side with the shock-absorbing pad 7 close to the lower surface of the tunnel. The shock-absorbing effect, through the cooperation of the shock-absorbing pad 7 and the shock-absorbing layer 5, can be decompressed and damped when the pipeline one 1 and the pipeline two 2 are subjected to external strong pressure and strong earthquake, so as to avoid the pipeline one 1 and the pipeline two 2 from being affected by the shock. The strong pressure and earthquake cause damage and cause leakage, and the anti-seepage layer 4 is set close to the left inner tube 3 and the right inner tube 15. When the left inner tube 3 and the right inner tube 15 are slightly damaged, it can play an anti-seepage effect. To avoid the damaged part, the damage gap is enlarged due to the leakage of water flow; at the same time, the outer tube 6 can play an external protective effect on the left inner tube 3 and the right inner tube 15, so as to avoid leakage caused by accidental damage of the left inner tube 3 and the right inner tube 15, Thus, the anti-seepage effect is improved.
