Abstract

The invention provides a tunnel steel lining installation system and a construction method. The tunnel steel lining installation system comprises a steel lining assembly, a hoisting frame, an installation rack and a rail car. The steel lining assembly comprises a pair of steel lining half bodies, the mounting rack comprises an umbrella supporting mechanism and a lifting mechanism, the umbrella supporting mechanism is used for driving the steel lining half bodies on the two sides to rotate, and the lifting mechanism is used for driving the umbrella supporting mechanism to move up and down. Firstly, the steel lining assembly is assembled outside a tunnel, then the steel lining assembly is placed on the mounting rack through the lifting frame, and the steel lining assembly is transferred through the rail car. In the installation process, the umbrella supporting mechanism and the lifting mechanism are adjusted, so that the steel lining half bodies on the two sides can be conveniently supported and moved in place, the steel lining half bodies are attached to an original tunnel lining to be maintained and reinforced, and the steel lining is completely installed. Therefore, under the limitation of skylight time, installation of the whole-ring and whole-section steel lining is ensured to be completed, and a new complete tunnel lining structure system is formed. Once the steel lining is installed, normal operation of the railway can be recovered, and driving safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of railway tunnel disease control, in particular to a tunnel steel lining installation system and construction method. Background technique [0002] Railway tunnel diseases include lining cracking, spalling, falling blocks, water leakage and so on. Tunnel diseases affect normal driving and endanger driving safety. [0003] In view of the time limit of "skylight (that is, the time reserved for maintenance of the railway every day, generally 4 hours)", the current disease control of railway tunnels mostly uses sprayed concrete in the tunnel lining or sprayed concrete with reinforced mesh, and grouting, etc. Ba" way. [0004] However, the tunnel lining repaired by the "padding" method can only be partially improved temporarily, and there are still risks of water leakage, lining peeling off and other risks that endanger driving safety. Contents of the invention [0005] The invention provides a tunnel steel...
