Tunnel crack reinforcing method

Abstract

The invention discloses a tunnel crack reinforcing method. The tunnel crack reinforcing method comprises the following steps that S1, the surface of soil around a crack is cleared to form a to-be-reinforced face, a reinforcement mesh is hung on the to-be-reinforced face, and polymer mortar is poured; S2, crack sealing glue is poured into the crack; and S3, a plurality of steel plates are anchoredin the direction of the crack path at intervals. According to the tunnel crack reinforcing method, the reinforcement mesh is arranged on the to-be-reinforced face, the reinforcement mesh and the tunnel soil form an integral structure, the stress at the tunnel crack can be effectively lowered, and the situation that the crack is further expanded and consequently partial collapse of the soil is caused is prevented; meanwhile, the crack sealing glue is poured into the crack, the steel plates are laid on the surface of the crack, thus the crack is filled, the surface of the crack is also blocked through chemical anchoring bolts and the steel plates glued by sticky steel glue, the situation that external water permeates into tunnel concrete through the crack is reduced, meanwhile, the reinforcing effect of the steel plates at the crack is also utilized, thus the bearing capability of the tunnel concrete is improved, and the service life of the tunnel concrete is prolonged.

Description

technical field [0001] The invention relates to the technical field of tunnel reinforcement, and more specifically, the invention relates to a tunnel crack reinforcement method. Background technique [0002] With the long-term use of the tunnel, different degrees of cracks will appear on the tunnel. If it is not repaired and repaired in time, the damage to the road surface and bridge deck will be aggravated. The traditional solution is to fill it. This method is used for a period of time to repair the cracks. Also can occur same crack, therefore be badly in need of a kind of tunnel crack reinforcing method, after it is repaired to crack, firm, long service life. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be described later. [0004] Still another object of the present invention is to provide a method for reinforcing tunnel cracks. By arranging ...

Problems solved by technology

[0002] With the long-term use of the tunnel, different degrees of cracks will appear on the tunnel. If it is not repaired and repaired in time, the damage to the road surface and bridge deck will be aggravated. The traditional solution is to fill it. This method is used for a period of time to repair the cracks. The same cracks will also appear, so there is an urgent need for a tunnel crack reinforcement method, which is stable and has a long service life after the cracks are repaired.
