Abstract

A shock-absorbing and energy-dissipating device for shield tunnel bolt joints belongs to the technical field of shield tunnel anti-seismic engineering. The shock absorption and energy dissipation device of the shield tunnel bolt joint includes a joint gasket, a first rubber gasket, a first sleeve, a second rubber gasket, a second sleeve and a third rubber gasket arranged coaxially in sequence. A sleeve is provided with a first elastic waterproof sealing ring and a second elastic waterproof sealing ring. The first sleeve is evenly provided with several protrusions along the circumferential direction, and each protrusion is equipped with a shock-absorbing spring. The springs are each provided with circular gaskets, the first rubber washer is provided with several through holes corresponding to the protrusions, the second sleeve is provided with a third step groove, and the third rubber washer is provided with a third step corresponding to the third step groove. There are three step protrusions, and the third step groove is provided with a third elastic waterproof sealing ring. The shock-absorbing and energy-dissipating device for shield tunnel bolt joints is easy to install, has strong shock-absorbing and energy-dissipating effects, can effectively attenuate vibrations, and also has a good waterproof effect.

Description

technical field [0001] The invention relates to the technical field of shield tunnel anti-seismic engineering, in particular to a shock-absorbing and energy-dissipating device for bolt joints of shield tunnels. Background technique [0002] The tunnel is underground, its force and deformation are closely related to the surrounding environment, and it is a prefabricated structure, resulting in very complicated force and deformation. In the disaster investigation of subway tunnels, it was found that, for example, the upper and lower crossing tunnels, under the impact of repeated dynamic loads from earthquakes, a series of failure forms such as bolt breakage and local concrete cracking at the joints will occur, which will eventually lead to water leakage and other problems. [0003] In subway tunnels, the requirements for tunnel shock absorption are very high, but the shock absorption design of bolt joints is still relatively lacking. For example, in special tunnels such as upp...
