Problems solved by technology

There are many problems in the construction process of the steel arch frame: one is that after the excavation of the tunnel in the expansive soil layer, the deformation of the surrounding rock of the tunnel is relatively large, and the deformation can reach 20-40cm, which causes the steel arch frame to bear a lot of pressure and is very prone to accidents. extrusion deformation failure
At present, to find the device that solves the above problems does not yet exist

Abstract

The invention relates to a tunnel lining structure with a detachable lining tire and a construction installation method thereof. The tunnel lining structure comprises the lining tire, a pressure force meter, an alarm device, strain pieces, U-shaped expansion bolts and the like. By means of the tunnel lining structure with the detachable lining tire and the construction installation method thereof, in the construction process, the internal force of a steel arch does not increase when surrounding rocks deform, the surrounding rocks produce supporting force all the time, local damage does not happen on the surrounding rocks, and it can be guaranteed that when the steel arch is damaged, large internal force does not occur simultaneously. The tunnel lining structure with the detachable lining tire and the construction installation method thereof has the advantages that the tunnel lining structure with the detachable lining tire is suitable for tunnels with various shapes, sustaining strength of the surrounding rocks can be exerted adequately, it is guaranteed that the whole steel arch is uniformly forced, sudden damage of the surrounding rocks is prevented in the construction process, the safety property is improved, the steel arch can be dismantled in the late construction, and the tunnel construction cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of tunnel engineering devices, in particular to a tunnel lining structure with detachable lining tires and a construction and installation method thereof. Background technique [0002] Nowadays, with the continuous development of my country's transportation network, the construction of tunnel projects is becoming more and more huge, and the problem of soft rock and expansive soil layers in tunnels has become an urgent problem to be solved. There are many problems in the construction process of the steel arch frame: one is that after the excavation of the tunnel in the expansive soil layer, the deformation of the surrounding rock of the tunnel is relatively large, and the deformation can reach 20-40cm, which causes the steel arch frame to bear a lot of pressure and is very prone to accidents. Extrusion deformation damage. The second is that the steel arch is installed too early, and the deformation of the surrounding ...
