Problems solved by technology

Larger-diameter cement pipes include square pipes and round pipes, which are prefabricated or cast on site with cement and steel bars. The overall cost of the project is high, easy to leak, easy to crack, and poor internal pressure resistance; Many, construction is difficult; during construction, the foundation must be done first, and the construction cost is relatively high
Plastic pipe is made of plastic resin as raw material, adding stabilizer and other additives, and extruding in the pipe making machine. It is light in weight; easy to process, but small in diameter; low in mechanical strength, poor in damage resistance, and not wear-resistant damaged, not fire-resistant, as a space structural pipe, it cannot meet the fire-fighting requirements
The caliber of ordinary carbon steel pipes cannot be made too large, generally only up to 2.5 meters, and the maximum diameter of the national standard is 2.4 meters. When the caliber is large, the pipe wall is greatly thickened and the cost is high.

Abstract

The invention discloses a steel-concrete combined structure pipeline with a spiral reinforcing ring and a manufacturing method of the steel-concrete combined structure pipeline. The steel-concrete combined structure pipeline comprises a pipe body. The surface of the pipe body extends outwards to form a protruding rib spirally arranged on the outer wall of the pipe body. A groove is formed by the protruding rib and the pipe body and provided with a blocking steel belt for blocking a groove opening of the groove. The hollow reinforcing ring is formed between the protruding rib and the blocking steel belt and filled with concrete. The steel-concrete combined structure pipeline has the advantages that by additionally arranging the spiral reinforcing ring integrally formed together with the pipe body, the annular strength of the pipeline is enhanced; by filling the reinforcing ring with concrete, the pressure resistant strength of the pipe body is further improved; by means of the pipeline, the purpose of using large-size steel structure products in underground common pipeline projects, underground comprehensive pipe galleries and underground traffic roads and metros is achieved; meanwhile, the method is easy to operate, easy and convenient to construct and capable of shortening construction period and reducing cost.

Description

technical field [0001] The invention relates to a pipe and a manufacturing method thereof, in particular to a steel-concrete composite structure pipe with a spiral reinforcing ring and a manufacturing method thereof. Background technique [0002] At present, in pipeline engineering, commonly used pipelines include cement pipes, plastic pipes, ordinary carbon steel pipes, stainless steel pipes and galvanized steel pipes, etc. Larger-diameter cement pipes include square pipes and round pipes, which are prefabricated or cast on site with cement and steel bars. The overall cost of the project is high, easy to leak, easy to crack, and poor internal pressure resistance; Many, construction is difficult; during construction, the foundation must be done first, and the construction cost is relatively high. Plastic pipe is made of plastic resin as raw material, adding stabilizer and other additives, and extruding in the pipe making machine. It is light in weight; easy to process, but ...
