An anti-seismic support and its construction method

Abstract

The invention provides an anti-seismic bracket and a construction method thereof, and relates to the technical field of underground construction protection. The anti-seismic bracket comprises two baseassemblies, an outer bearing force bracket is jointly connected to the upper surfaces of the two base assemblies, an inner protection bracket is jointly connected to the position, located on the inner side of the outer bearing force bracket, of the upper surfaces of the two base assemblies, a plurality of supporting columns are fixedly connected between the outer bearing force bracket and the inner protection bracket, and connecting columns are arranged between the two adjacent supporting columns. By designing the double-layer arch bracket, a double supporting effect can be achieved for an underground tunnel, the supporting columns and the connecting columns further reinforce the outer bearing force bracket and the inner protection bracket, when the outer bearing force bracket is damagedby external force, the inner protection bracket still has a supporting function, the situation of serious collapse cannot happen, after the occurrence of an irresistible force accident, the damage degree of the whole bracket and the underground tunnel is small, and the safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of underground engineering protection, in particular to an anti-seismic support and a construction method thereof. Background technique [0002] Underground engineering is an engineering building built underground or below the bottom of the water. Modern underground construction projects have been widely developed in mining, underground transportation, municipal, industrial and water underground construction projects. , modern underground construction projects, began to be widely developed in mining, underground transportation, municipal, industrial and hydraulic underground construction projects, such as mines and roadways, railway tunnels and road tunnels, underground railways and underwater tunnels, underground warehouses And oil depots, as well as various uses of water and other hydraulic tunnels.

AI Technical Summary

Problems solved by technology

[0003] In order to further ensure the safety of underground work, various protective brackets are installed in many underground tunnels. The protective brackets have a certain supporting effect on the tunnels and improve the safety level of underground tunnels to a certain extent. However, what we currently have The protective brackets seen are generally directly supported by the steel structure on the inner wall of the tunnel. These protective brackets are prone to comprehensive collapse when encountering high pressure, and the existing protective brackets have unsatisfactory anti-seismic effects. Once an accident occurs , the degree of damage is more serious
