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 detachable lining tires and a construction and installation method thereof. The tunnel lining structure includes lining tires, a pressure dynamometer, an alarm device, a strain gauge, a "U"-shaped expansion bolt and the like. The invention solves the problem that during the construction process, the surrounding rock deforms without increasing the internal force of the steel arch, and there is always a supporting force in the surrounding rock, so that the surrounding rock will not be partially damaged, and at the same time, it can ensure that the steel arch will not produce a large amount of damage when it is damaged. The problem of large internal stress. The invention is suitable for tunnels of various shapes, which can fully exert the self-supporting force of the surrounding rock, ensure that the overall force of the steel arch frame is uniform, prevent the surrounding rock from being suddenly damaged during the construction process, and improve safety. The steel arch can be removed in the later stage of construction. The arch frame greatly saves the cost of tunnel construction.

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 ...
