In hydraulic engineering, the construction quality of water stopping engineering plays an important role in the service life of the engineering, and if the water stopping engineering is unqualified, the water seepage of a hydraulic structure is too early, the structure is corroded, and the service life of the engineering is shortened. Water stopping forms in hydraulic engineering generally comprise a rubber water stopping belt and a copper sheet water stopping form. The rubber waterstop utilizes the high elasticity of rubber to generate elastic deformation under various pressure loads, thereby playing a role in firm sealing, effectively preventing water leakage of a building structure, seeping water and playing a role in damping and buffering. In many large-scale hydraulic engineering, the water and soil structures have certain requirements on extension and retraction, and the requirements on water resistance, shock resistance and the like exist, and the problems can be effectively solved by adopting the rubber waterstop. The copper sheet water stop is widely applied to engineering seam water stop and is a metal water stop material with the best water seepage prevention and water stop effects in hydraulic engineering due to the advantages of high tensile strength, strong erosion resistance, good toughness, capability of bearing large deformation, clear appearance outline, no crack, no fold, no pit and the like. Therefore, some key parts in a large-scale water conservancy project, such as key expansion joints or settlement joints, usually adopt a form of combining water stopping of a rubber water stopping belt and water stopping of a copper sheet.
