[0002] Water pipes are pipes that supply water. In modern renovations, water pipes are typically installed by embedding them in walls. There are three main types of water pipes: The first type is metal pipes, such as hot-dip galvanized cast iron pipes with internal plastic lining, copper pipes, and stainless steel pipes. The second type is plastic-coated metal pipes, such as steel-plastic composite pipes and aluminum-plastic composite pipes. The third type is plastic pipes, such as PB pipes and PP-R pipes.

[0003] Among them, the water-blocking device and method for water supply pipeline maintenance with application number "CN202310792790.0" includes a support member and a receiving member fixedly connected to the support member via a connecting plate, a transmission rod, the transmission rod being fixedly installed on the receiving member and concentrically arranged with the support member, a top plate being fixed to the end of the transmission rod away from the receiving member, a plurality of support plates being circumferentially arranged and hinged to the top plate, a slider arranged in a ring shape being slidably installed on the transmission rod, a second transmission plate being hinged to the slider and hinged to the support plate, and a sealing member, the sealing member being fixedly installed on the top plate and the support plate, and driving a threaded transmission cylinder to move radially along the threaded rod, and passing multiple The second transmission plate drives multiple support plates to rotate, moving them from a converged state to an open state. Further research revealed a water-blocking device with application number "CN201420013185.5," which includes a grout inlet pipe equipped with an anti-surge water device. The anti-surge water device is clamped onto the grout inlet pipe. One end of the grout inlet pipe is connected to a grout inlet, which is fitted inside the inlet and secured with bolts. The inlet is connected to a borehole pipe, which passes through a grouting tee and is fitted into a hollow cylinder, also secured with bolts.
