Description
Technical Field
The utility model belongs to the technical field of waterproof stripe, especially, relate to an adhesive tape for tunnel movement joint.
Background
With the rapid development of the economy of China, various infrastructures of China are continuously developed and perfected. Due to the complex terrain and regions, a large number of tunnels are required to be constructed to meet the production and living requirements when infrastructure such as roads, railways and the like are constructed. In tunnel construction, an inevitable joint surface, namely a construction joint, exists between an original old concrete structure and newly poured concrete, and a deformation joint of a tunnel lining structure is a key part of a waterproof design, so that the tunnel lining structure is free from leakage, seepage and wet stain. Because the shrinkage of the old concrete is finished and the shrinkage of the new concrete is just started, the shrinkage of the new concrete and the old concrete must cause shearing or stretching at a joint surface to form cracks, so that the new concrete and the old concrete cannot work together, the problems of water seepage, water leakage and the like are caused between the new concrete and the old concrete, and the durability and the service performance of the tunnel structure are seriously influenced. At present, a rubber water stop is adopted in the waterproof design of the secondary lining deformation joint of the railway tunnel, and the current rubber water stop is a solid body, so that the deformation at the joint is reduced, and a certain influence is generated on the waterproof effect.
