Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawing.

[0035] When there is water leakage in the operating tunnel, it can first be investigated and dealt with on-site to determine the severity of the leakage problem and record it. According to the requirements of the specification, the disease situation is graded and treated, and the diseased part is marked with ink and relevant key information is marked on the diseased part. Rinse and clean the diseased part with high-pressure water, and cut out two grooves with a depth of about 5mm on both sides of the leak point, and insert the two wings of the water guide plate here, and make an arched guide according to actual requirements. Water structure 1 (such as figure 1 and figure 2 shown), horizontal water guide structure 2 (such as image 3 and Figure 4 shown), longitudinal water guide structure 3 (such as Figure 5 and Image 6 shown) and side ditch water guide structure 4 ...

Abstract

The invention relates to a method for treating operating tunnel leakage with a water diversion plate. The method comprises the steps of determining the size of the water diversion plate according to the water leakage condition, obtaining two grooves on the two sides of the leaked position through cutting, installing the water diversion plate on the grooves, continuing to lay the water diversion plate on the inner wall of a tunnel, sealing the water diversion plate and the inner wall of the tunnel, and spraying a waterproof coating onto the outer side of the water diversion plate to form a water diversion pipeline so that water can be guided to side ditches of the tunnel. The ultrathin water diversion plate is prefabricated, the plate is extremely thin, a groove is shallow and narrow, weight is low, material consumption is low, and the influence on the appearance of the tunnel after installation is small. The water diversion technology of the ultrathin water diversion plate is convenient to implement, drilling and grouting are not needed, it is only needed to arrange a water diversion plate circuit outside the tunnel, construction is convenient and quick, and disturbance of the tunnel is light. The ultrathin water diversion plate is made of resin or glass fiber, is high in durability, and can serve as a tunnel surface drainage system to be used for a long time so as to improve the drainage capacity of the tunnel.

Description

technical field [0001] The invention relates to a method for controlling water leakage of an operating tunnel by using a water guide plate. technical background [0002] During the operation of the tunnel, there may still be groundwater leakage in the tunnel due to old materials or external effects, and the original waterproof and drainage system of the tunnel cannot better meet the requirements of keeping the tunnel dry, and for the tunnel line Due to the large flow of groundwater, the waterstop and waterproof boards laid will also fail, and a large amount of groundwater will gush out, which will affect driving safety in serious cases and cause the function of the tunnel to fail. [0003] At present, the commonly used methods for tunnel water leakage include water stop method, waterproof method and drainage method. The water-stopping method can be divided into the water-blocking agent method and the grouting method. The water-blocking agent is only suitable for small water...
