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 Figure 6 shown) and side ditch water guide structure 4...

Abstract

The invention relates to a method for controlling water leakage in an operating tunnel by using a water guide plate, which comprises the following steps: determining the size of the water guide plate according to the water leakage situation, cutting two grooves at the positions on both sides of the leaking part, and installing the water guide plate on the groove. Water plate, continue to lay the water guide plate on the inner wall of the tunnel, seal the water guide plate and the inner wall of the tunnel, and then spray waterproof paint on the outside of the water guide plate to form a water guide pipeline to guide water to the tunnel side ditch. The ultra-thin water guide plate is prefabricated, the plate is extremely thin, the groove is shallow, the width is small, the quality is light, the consumables are less, and the impact on the appearance of the tunnel after installation is small. The ultra-thin water-guiding plate water-guiding process is easy to construct, without drilling and grouting, and only needs to arrange the water-guiding plate lines on the outer surface of the tunnel. The construction is convenient and fast, and the disturbance to the tunnel is minimal. The ultra-thin water guide plate is made of resin material or glass fiber, which has good durability and can be used as a drainage system on the surface of the tunnel, which can be used for a long time and enhance 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...
