The utility model relates to a
polyethylene composite
steel frame concrete
water supply and drainage
pipe. Comprising an inner-layer
polyethylene pipe, the periphery of the inner-layer
polyethylene pipe is sleeved with a
steel frame cage, and the periphery of the
steel frame cage is sleeved with an outer-layer polyethylene pipe; a plurality of protruding heads are fixedly arranged on the outer wall of the inner-layer polyethylene pipe and the inner wall of the outer-layer polyethylene pipe; a layer of
adhesive is attached to the surface of the outer-layer polyethylene pipe, a layer of
adhesive is attached to the surface of the inner-layer polyethylene pipe, then a
cement mortar layer is poured, and the steel frame cage is located in the
cement mortar layer. The steel frame cage, the
cement mortar, the inner polyethylene pipe and the outer polyethylene pipe are integrated and are not easy to delaminate; the pipe adopts a socket type electric melting connection mode, so that the joint of the pipe is not easy to leak water. The inner wall of the pipe is flat and smooth, impurities in water are not easy to precipitate in the pipe, the inner
diameter of the pipe cannot be reduced, and the pipe cannot be blocked; the pipe provided by the utility model adopts a double-insurance socket-and-spigot type electric melting connection mode, so that joints are not easy to fall off, and
water leakage is not easy to occur.
