Abstract

The invention discloses a damping energy dissipation device of a shield tunnel bolt joint, and belongs to the technical field of shield tunnel shockproof engineering. The damping energy dissipation device comprises a joint gasket, a first rubber gasket, a first sleeve, a second rubber gasket, a second sleeve and a third rubber gasket which are coaxially arranged in sequence, the first sleeve is provided with a first elastic waterproof sealing ring and a second elastic waterproof sealing ring, a plurality of protrusions are uniformly arranged on the first sleeve in the circumferential direction, each protrusion is sleeved with a damping spring, each damping spring is provided with a round gasket, a plurality of through holes corresponding to the protrusions are formed in the first rubber gasket, the second sleeve is provided with a third step groove, the third rubber gasket is provided with a third step protrusion corresponding to the third step groove, and the third step groove is provided with a third elastic waterproof sealing ring. The damping energy dissipation device has the advantages of being convenient to install, high in damping energy dissipation effect, capable of effectively achieving attenuation vibration and good in 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...
