A tunnel lining leakage water treatment method

Abstract

The invention provides a tunnel lining leakage water treatment method. The method comprises the steps of selecting water diversion hole point locations; cutting crevices along a crevice by using a handheld concrete crevice cutter; chiseling away concrete to form an inverted trapezoid groove; cutting a crevice along the crevice from the surface of a lining above a high water diversion point and cutting a crevice along the crevice from the bottom of the groove below the high water diversion point; chiseling away concrete to form a rectangular groove with the depth greater than the width; performing groove cleaning treatment; performing grouting treatment on the rectangular groove by using epoxy resin mortar to block leakage water; drilling water diversion holes at the marking points to lead the leakage water out; installing a composite water-swelling rubber strip in the inverted trapezoid groove and fixing the rubber strip to form a water diversion channel; using waterproof adhesive cement to seal the gap between the composite water-swelling rubber strip and the groove wall of the groove; filling the inverted trapezoid groove solidly with hydrophilic epoxy mortar; performing plastering treatment to finish the whole process. Water flow flows into the groove through the water diversion holes and is guided to the bottom of a cable trench and to a side trench and the outside of a tunnel.

Description

technical field [0001] The invention relates to a method for treating leakage water, in particular to a method for treating leakage water in tunnel lining for rectifying tunnel disease. Background technique [0002] With the continuous expansion of the operating mileage of highways and railways in our country, the number of tunnels continues to increase, and it is inevitable that there will be diseases during the tunnel operation stage, among which water leakage has an important impact on the safe operation of the tunnel. Due to water leakage from the tunnel, the air humidity in the tunnel increases, causing damage to facilities such as rails, communications, and lighting; water leakage through the lining will accelerate the carbonation rate of the concrete, corrode the steel bars, damage the lining structure, and reduce the service life of the tunnel. [0003] The Chinese Patent No. CN102108873 discloses a grouting method for rapid treatment of tunnel leakage water. This me...

Problems solved by technology

Due to water leakage in the tunnel, the air humidity in the tunnel increases, causing damage to rails, communications, lighting and other facilities; water leakage through the lining will accelerate the carbonation rate of the concrete, corrode the steel bars, damage the lining structure, and reduce the service life of the tunnel

[0003] The Chinese Patent No. CN102108873 discloses a grouting method for rapid treatment of tunnel leakage water. This method only seals the cracks by "blocking" to achieve the goal of treatment, but strong plugging will increase the lining back. The pressure of the accumulated water, causing new leakage in other weak parts of the lining

[0004] At present, the treatment of seepage water is mainly based on "blocking", and some are treated by diversion and drainage. These are relatively simple treatment methods and cannot effectively control the seepage water
