Description

Technical Field

[0001] The invention belongs to the technical field of water-stopping and anti-seepage repair, and in particular relates to a device and method for continuously laying a joint water-stopping structure on a slope surface with a large water depth. Background Art

[0002] With the continuous advancement of science and technology, in order to meet the needs of national and urban development, the construction depth of water-related buildings in water conservancy projects has reached hundreds of meters. According to statistics, there are more than 164 dams over 100 meters in my country. For example, the newly built Baihetan Hydropower Station, a national heavy equipment, has a flooding depth of 280m after water storage. The construction depth of underwater structures involving the ocean may reach hundreds to thousands of meters in deep sea areas. As the service life of reservoir dams and ports and coastal anti-seepage buildings increases, more and more leakage problems are highlighted. The main reason is that the aging of the water-stopping structural materials of the joints of the buildings during the construction process and the settlement and tensioning of the original foundation lead to water seepage at the joints. Leakage, especially under high head conditions, will cause major safety hazards to buildings, so timely underwater inspections and anti-seepage repairs are required during the operation of the buildings.

[0003] At present, the repair method for underwater anti-seepage structures is to replace the original failed water-stopping module underwater, and repair the structural parts at a depth of less than 60m according to the diving operation decompression specification. Divers can use pipe-supplied air diving to manually repair the structure, and the operation cost, efficiency and safety risks are relatively controllable. However, when the depth is greater than 60m, divers need to breathe mixed gas or saturated gas diving to carry out underwater repairs, and the cost of the gas source and supporting equipment for mixed gas and saturated gas diving increases sharply, and divers have greater risks and lower efficiency in working under deep water conditions.

[0004] The present invention designs a device and method for continuously laying a joint water-stopping structure on a deep water slope surface to solve the above problems. Summary of the invention

[0013] Step 4: Start the push roller, which pushes the water-stop module toward the trolley system through friction, so that the head of the water-stop module contacts the shaping groove.
