Embodiment Construction
[0028] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see figure 1 — figure 2 :
[0029] The polyethylene double-wall corrugated pipe material for buried drainage with a steel hoop 13 reinforced structure includes a polyethylene pipe 10 and a flared portion 17 is arranged at one end of the polyethylene pipe 10, and the outer surface of the polyethylene pipe 10 is axially The spacer set consists of an annular closed steel hoop 13 with a “door” or semi-elliptical or semicircular cross-section on one side. The support feet 12 on the surface, the steel hoop 13 and the outer surface of the support feet 12 and the polyethylene pipe 10 are integrally formed with a polyethylene coating 11 .
[0030] The two side walls 18 of the above-mentioned "door"-shaped steel hoop 13 are inclined outward to form a trapezoidal structure.
[0031] A closed annular hole 14 is formed between the outer surface of the polyeth...

The invention belongs to the technical field of underground drainage pipes and relates to a PE (polyethylene) double-wall corrugated pipe provided with a steel hoop reinforcement structure and applied to underground drainage. The PE double-wall corrugated pipe comprises a PE pipe and a flaring part arranged at one end of the PE pipe, wherein annular closed steel hoops with n-shaped, semi-elliptical or semi-circular unilateral sections are axially mounted on the outer surface of the PE pipe at intervals in a sleeving manner; end parts of side walls of the steel hoops are axially extend outwards to form propping feet attached to the outer surface of the PE pipe; a PE coating layer is integrally formed on outer surfaces of the steel hoops and propping feet and the PE pipe. The PE double-wall corrugated pipe has the advantages of high structural strength and ring stiffness, high production efficiency, low product cost, simplicity and convenience in connection, rapidness in construction, avoidance of pollution to the stratum environment and long service life, facilitates recycling and is suitable for underground drainage plastic pipes for municipal administration and construction zones.
Description
technical field [0001] The invention belongs to the technical field of buried drainage pipes, in particular to a polyethylene double-wall corrugated pipe for buried drainage with steel hoop reinforcement structure. Background technique [0002] At present, there are two types of plastic pipes used in municipal and construction area buried drainage pipe systems, steel belt reinforced structural wall pipes, polyethylene (PE) plastic pipes and steel belt reinforced structural wall pipes: one is steel belt reinforced spiral corrugated pipes Pipe, the other is steel belt reinforced spiral reinforced pipe. [0003] The characteristics of the pipe material in the prior art: one is a single or 2-4 co-extrusion structure wall, which is continuously wound into an open-loop spiral coil through a circumferential spiral. After the front coil is cooled, the rear coil is reheated by an external flame or hot melt adhesive and The front ring is lapped to form a circular pipe, which has low ...
