The invention provides a reinforced concrete pipe and a construction method, and relates to the technical field of road construction. The reinforced concrete pipe comprises a reinforced concrete pipe body, wherein the reinforced concrete pipe body combines modified polyvinyl chloride rubber sheets into the pipe to form a liner; and a pipeline connector of the reinforced concrete pipe body is subjected to hot-melt welding through a polyvinyl chloride (PVC) lap joint tape. The process of the hot-melt welding comprises that matching surfaces of two reinforced concrete pipelines are heat, two fused end surfaces are fastened together after the smooth end surfaces of the matching surfaces are melted, and the fastening is maintained under the action of pressure until a joint head cools down and become an integrated one. According to the reinforced concrete pipe and the construction method, by lining the existing reinforced concrete pipe, the defect that the reinforced concrete pipe is prone to leak at the connector is overcome, and the running life of the urban drainage network can be prolonged.
Description
Technical field [0001] The invention belongs to the technical field of road construction, and in particular relates to a reinforced concrete pipe and a construction method. Background technique [0002] Reinforced concrete pipes can generally save about 70% of steel material than steel pipes, reduce the cost by about 60%, and have higher crack resistance and better impermeability. Countries all over the world are actively promoting and expanding production, and developing in the direction of large diameter, light weight and high strength. Reinforced concrete pipes are used to transport water, oil, gas and other fluids, and can replace steel pipes and cast iron pipes. They are currently commonly used water supply pipes in small towns in my country. Traditional reinforced concrete pipes have problems such as poor chemical resistance, easy leakage at the pipe joints, and large impacts of geological settlement, which restrict the application of reinforced concrete pipes in more muni...
