AI Technical Summary

Technical Problem

Shield tunnels face vibration and water leakage problems during long-term operation. Existing vibration reduction and waterproofing technologies are difficult to optimize synergistically and cannot meet the high standards required by modern underground engineering.

Method used

A vibration-damping, waterproof and impact-resistant liner for the longitudinal circumferential joint of a shield tunnel is designed. The liner includes a liner matrix, a waterproof structure, an impact-resistant and vibration-damping support unit, a vibration wave dissipation medium and a water leakage monitoring module. The liner performance is optimized by using high-damping materials and a waterproof structure, and remote monitoring is achieved by combining a piezoelectric energy storage module.

Benefits of technology

It effectively weakens the vibration waves between the segments, prevents water leakage from entering the tunnel, enhances structural stability and impact resistance, and realizes early warning of leakage and disaster prevention and control throughout the entire life cycle.

Abstract

The invention discloses a vibration-damping waterproof shock-resistant gasket and method for a longitudinal circular seam of a shield tunnel. The vibration-damping waterproof shock-resistant gasket comprises a gasket base body, the face, making contact with a pipe piece, of the gasket base body is a plane, the face, making contact with the adjacent gasket base body, of the gasket base body is an arc face, and a waterproof structure is assembled on the surface of the arc face; a hollow separation cavity is formed in the liner base body; the anti-impact vibration reduction supporting units are arranged in the hollow partition cavity in a matrix mode; the vibration wave dissipation medium is filled in the hollow separation cavity and is positioned between the anti-impact vibration reduction supporting units; the water leakage identification module is embedded in the surface of the waterproof structure; and the signal transmission module is used for transmitting the digital signal identified by the water leakage identification module to the shield tunnel disease monitoring module. Vibration waves transmitted between shield tunnel segments can be effectively weakened, water leakage, caused by slab staggering and other diseases, of the shield tunnel near-soil side through the segment sealing strip can be monitored in time, the phenomenon of damage or stress concentration generated at the joints when the segments are spliced and used is avoided, and the maintenance cost is saved.
