Application of Pressure Plate Type Waterstop in South-to-North Water Diversion Project

The construction technology of pressure plate type waterstop in hydraulic engineering is more and more widely applied, especially in the defect treatment of concrete waterstop. The pressure plate type water stop used to process the surface of construction joint boasts the advantages of simple construction procedure, short time, lower cost savings and replaceable ability. This paper mainly introduces the application of pressure plate waterstop in the process of concrete construction joint, it describes the properties and features of the material of pressure plate type waterstop. Combined with a project in South-to-North Water diversion project, the paper illustrates the construction technology and key points in quality control of pressure plate type waterstop step by step.
