Abstract

The invention provides a tunnel reinforcing structure and a construction method thereof. The tunnel reinforcing structure comprises an annular reinforcing unit, the annular reinforcing unit comprisesmultiple first corrugated plates, at least one second corrugated plate mounted on the vault of the tunnel, and at least one base plate, the multiple first corrugated plates on the two sides of the vault are sequentially laid from bottom to top, one end of the second corrugated plate is connected with one first corrugated plate at the tail end in the paving direction, a gap is formed between the other end of the second corrugated plate and the other one first corrugated plate on the tail end in the paving direction or formed between two second corrugated plates, the base plate is clamped in thegap to enable the annular reinforcing unit to be in closed paving, in the tunnel reinforcing structure, the second corrugated plate and the base plate are flexible in size setting, the problem that an annular reinforcing unit is difficult in closure is solved, mounting is easy, the mounting time is greatly shortened, and the construction finishing of the tunnel reinforcing structure in the skylight time segment can be ensured.

Description

technical field [0001] The invention relates to the technical field of tunnel disease treatment, in particular to a tunnel reinforcement structure and a construction method thereof. Background technique [0002] The lining structure of tunnels such as railways and subways is prone to cracking, block loss, mesh cracking, water leakage, frost heave and other diseases, which seriously threaten the operation safety of railways and subways. Due to the limitation of skylight time of existing lines, tunnel boundary, construction period, construction cost, tunnel operation space and construction environment, the existing remediation methods often fail to achieve the expected results, resulting in repeated occurrence of tunnel diseases, which are difficult to cure. Relatively speaking, the use of corrugated plate lining technology to strengthen tunnels has certain advantages. However, the reinforcement of operating tunnels generally utilizes skylight time, and the operation time is ...
