Tunnel defect treatment method

Abstract

The invention discloses a tunnel defect treatment method. The tunnel defect treatment method comprises the steps that S10, lining concrete of a tunnel is detected to obtain defects of the lining concrete; and S20, different treatment measures are used for different concrete defects. One or more of a radar detection method, a knock detection method, a perforation detection method and a coring detection method is used for detecting the lining concrete of the tunnel, the situation of the concrete defects is obtained, and different repair methods are adopted according to different defects. The tunnel defects can be quickly and efficiently repaired, and at least one of the technical problems is solved.

Description

technical field [0001] The invention relates to the technical field of tunnels, in particular to a tunnel defect treatment method. Background technique [0002] Our country is a mountainous country, so the amount of tunnels is also very large. The emptying and falling blocks of the operating tunnel have seriously affected the operational safety of the tunnel. At present, the main solution is the molded concrete replacement method. The advantages of the molded concrete replacement method: (1) It belongs to the traditional method, and the process maturity (2) The material is easy to prepare, and the equipment is relatively simple and easy to operate; (3) The use of steel arches or grid steel frames has a certain reinforcement effect. [0003] At the same time, this method also has very fatal shortcomings: (1) it needs to be dismantled and replaced, which has a high safety risk; (2) the construction period is long, and it cannot adapt to ordinary railways whose skylight time i...

Problems solved by technology

[0003] At the same time, this method also has very fatal shortcomings: (1) it needs to be dismantled and replaced, which has a high safety risk; (2) the construction period is long, and it cannot adapt to ordinary railways whose skylight time is less than 6 hours, and the cost is relatively high. Need to use a lot of manpower; (3) the quality of concrete is difficult to guarantee

Since the supporting formwork cannot be vibrated, the concrete density is poor, and it is easy to leak water or cause secondary problems
