Abstract

The invention discloses a pressure steel pipe reinforcement composite concrete pipe, a manufactured pipe and a manufacturing method. A pipe body consists of a concrete outer pipe, a rubber pipe, a steel pipe and a concrete inner pipe arranged in sequence from outside to inside; the manufactured pipe is to insert an insertion port part of one pipe into a bearing port part of the other pipe and to uniformly coat polysulfur sealing paste in the joined place. The manufacturing method comprises manufacturing of a bearing port steel ring and an insertion port steel ring, manufacturing of a steel pipe, derusting and polishing of the steel pipe, leakage point detecting, bonding of the rubber pipe, manufacturing of a reinforcement skeleton cage, installing of an inner mold, installing of the steel pipe and the reinforcement skeleton cage on a chassis, sleeving of an outer mold, inserting of concrete into the mold, vertical vibration molding, port leveling, removing of the inner and outer molds, coating of corrosion resisting paint on the surfaces of the bearing port steel ring and the insertion port steel ring, coating of polyurethane on the end surface, finishing and inspecting, marking and curing, and carrying out inspection. The product can effectively overcome the longitudinal crack phenomenon on the inner and outer walls of the pipe due to higher internal and external pressure on the pipe.

Description

technical field [0001] The invention relates to the field of water pipelines, in particular to a reinforced concrete pipe. Background technique [0002] Concrete pipes are mainly used to transport fluids such as water, oil, and gas, and can be divided into plain concrete pipes, ordinary reinforced concrete pipes, self-stressed reinforced concrete pipes, and prestressed concrete pipes. According to the different inner diameters of concrete pipes, they can be divided into small diameter pipes (below 400mm inner diameter), medium diameter pipes (400~1400mm) and large diameter pipes (above 1400mm). According to the different water pressure capacity of the pipe, it can be divided into low-pressure pipe and pressure pipe. The working pressure of the pressure pipe is generally 0.4, 0.6, 0.8, 1.0, 1.2 MPa, etc. Compared with steel pipes, concrete pipes can be divided into flat pipes, socket pipes and tongue and groove pipes according to the different types of pipe joints. The inte...
