Regenerated concrete dewatering pipe and manufacturing method thereof

Abstract

The invention discloses a regenerated concrete dewatering pipe which comprises a tubular body and a reinforcing rod embedded in the tubular body and extending along the axial direction of the same. The outer edge of an opening at one end of the tubular body is provided with an annular notch to form a connection plug while an opening at the other end radially expands to form an insertion connecting cavity, and the tubular body is composed of cement, fly ash, sand and regenerated gravel. The invention further discloses a manufacturing method of the regenerated concrete dewatering pipe. The regenerated concrete dewatering pipe is ingenious in structural design, reasonable in formula, high in integral structure strength, high in pressure bearing capacity and stable and firm in connection; building waste is utilized for regeneration, so that environment is protected; the regenerated concrete dewatering pipe is low in cost and simple and convenient to manufacture, so that competitiveness is improved, and good economic benefit and social benefit are realized. The manufacturing method is simple and easy in process, easy to realize and high in production efficiency, and the problem of regenerating utilization of the building waste can be solved while the regenerated concrete dewatering pipe is manufactured quickly.

Description

technical field [0001] The invention belongs to the technical field of drainage pipes, and in particular relates to a recycled concrete drainage pipe and a manufacturing method thereof. Background technique [0002] Drainage pipes are mainly responsible for the drainage of rainwater, sewage, farmland irrigation and drainage. Drain pipes are divided into concrete pipes and PVC pipes. The PVC pipe drainage pipe is made of sanitary polyvinyl chloride (PVC) resin as the main raw material, adding an appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., extruded by a plastic extruder and injected by an injection molding machine, and cooled , curing, shaping, inspection, packaging and other processes to complete the production of pipes and fittings. Its production process is relatively cumbersome, and the size is smaller than the design. Concrete pipes are pipes made of concrete or reinforced concrete, and the cost of raw materials is relatively high; moreov...

AI Technical Summary

Problems solved by technology

Concrete pipes are pipes made of concrete or reinforced concrete, and the cost of raw materials is relatively high; moreover, the connection effect between the pipes is not very ideal, it is difficult to locate when connecting, and it is easy to shift after the connection is used, resulting in leakage create pollution problems

[0003] However, at present, due to the rapid growth of population and the development of urbanization, the construction industry in central cities develops rapidly, and old buildings are torn down and demolished every day, resulting in more and more construction waste (among them, waste concrete accounts for 34%). In order to meet the needs of civil air defense and building functions, newly built multi-storey high-rise buildings adopt basement and pile foundation structures. The concrete horizontal support beams of the foundation pit and the pile heads of the overfilling project need to be removed, and a large number of concrete test blocks for construction projects are discarded. landfill

Landfilling of construction waste not only wastes resources, pollutes the environment, and destroys ecology, but also takes up a lot of land.
