Construction method of tunnel lining

Abstract

The invention belongs to the technical field of tunnel construction, and in particular, relates to a tunnel lining construction method, and aims to solve the problems of need of replanning of tunnel lining structures due to incapability of meeting sky train driving conditions by tunnel structures and no way to develop the construction work due to high design difficulty in sky train rail construction in tunnels in the prior art. The tunnel lining construction method comprises the following steps: (S1) the secondary lining preparation work is performed on the basis of finishing the primary lining and inverted arch constriction of tunnels to be constructed; (S2) waterproof plates are paved; and secondary lining reinforcements are bound; (S3) concrete is pumped to side edge walls on the two sides of the tunnels to form secondary lining main body structures; (S4) sky train rails and rail mounting frames are mounted; and (S5) the concrete is pumped to inverted arches of the tunnels. The tunnel lining construction method enables the sky train rails and the tunnel main bodies to form excellent stress wholes, is more stable, safer and more reliable in operation of sky trains, and is simplein structure, high in operability and low in cost.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a tunnel lining construction method. Background technique [0002] With the continuous acceleration of the urbanization process, the rapid expansion of the city scale, the acceleration of the pace of urban life and the sharp increase in the number of urban populations, people's travel volume is increasing. In order to alleviate traffic congestion, air rail is gradually being known by the public and applied to urban construction. . Skytrain is a suspended train transportation system whose tracks are above the vehicles. The air-rail vehicle belongs to the rail transit vehicle and needs to run on a relatively flat track. The track of the rail transit is a hard track, generally a steel track, such as a railway rail. The friction force provided by the hard track to the vehicle wheels is relatively small, so rail transit can have high speed and low-cost tracti...

Problems solved by technology

[0004] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the tunnel structure in the prior art cannot meet the running conditions of the air-rail train, it is necessary to re-plan the tunnel lining structure; the construction design of the empty-rail track in the tunnel is difficult, and it is difficult to know how to carry out the construction work question
