Description

TECHNICAL FIELD

[0001] The utility model relates to a pipeline, in particular to a double high rib reinforced pipe. BACKGROUND

[0002] In recent years, with the large demand for municipal pipeline, many plastic pipelines appear, such as PVC pipe, straight-through water pipe and winding corrugated pipe with rib pipe. The winding corrugated pipe with rib pipe is a kind of pipe wall on which the rib pipe spirally winds, and the strength of the pipe wall is strengthened by setting the rib pipe. However, the current winding corrugated pipe usually only has a hollow rib pipe, and when the winding corrugated pipe is buried underground, the hollow position of the rib pipe will be subjected to pressure from all directions of the soil layer, so the winding corrugated pipe is easy to be deformed under pressure, and when the winding corrugated pipe is buried in a place where vehicles pass frequently or earthquakes occur frequently, the ground vibration also easily causes the winding corrugated pipe to break, and the anti-pressure and anti-seismic ability is poor. SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a double high rib reinforced pipe, which has better anti-pressure and anti-seismic ability and is not easy to deform after the reinforced pipe is buried.

[0004] In order to solve the above technical problem, the technical scheme adopted is as follows:

[0005] A double high rib reinforced pipe, comprising a pipe body and a rib pipe, the rib pipe spirally winding on the outer wall of the pipe body along the length direction of the pipe body, the inner side wall of the rib pipe and the outer wall of the pipe body being fused together, and the inside of the rib pipe being hollow, characterized in that: the rib pipe comprises an outer pipe layer and a reinforcing high rib, the reinforcing high rib comprises two supporting inner pipes, the two supporting inner pipes are arranged side by side, and the outer pipe layer is wrapped outside the two supporting inner pipes and fused together with the two supporting inner pipes.

[0006] The rib pipe and the pipe body can be fused together by applying pressure and using residual heat when the pipe body and the rib pipe are respectively extruded and the rib pipe is wound outside the pipe body.

[0007] In the double high rib reinforced pipe, the reinforcing high rib is added inside the rib pipe to strengthen the reinforcing high rib, and since the reinforcing high rib is composed of two supporting inner pipes, the two supporting inner pipes can support each other, and the side walls of the two supporting inner pipes can jointly constitute a reinforcing rib extending along the length direction of the rib pipe, further improving the supporting ability of the rib pipe, thereby effectively enhancing the anti-pressure and anti-seismic ability of the entire double high rib reinforced pipe, which is not easy to deform after being buried underground, and even if affected by ground vibration, the double high rib reinforced pipe is not easy to break due to vibration, resulting in pipeline leakage.

[0008] The inner-outer direction is defined according to the axis of the pipe body, the position close to the axis of the pipe body is the inner, and the position far from the axis of the pipe body is the outer.

[0009] In the preferred embodiment, the inner wall of the supporting inner pipe is provided with a plurality of corrugated strips, each of which is arranged on the inner wall of the supporting inner pipe in parallel along the length direction of the supporting inner pipe, and the corrugated strips are perpendicular to the extending direction of the supporting inner pipe. By arranging the corrugated strips on the inner wall of the supporting inner pipe, the corrugated pipe can strengthen each position of the supporting inner pipe, and since the corrugated strips are perpendicular to the extending direction of the supporting inner pipe, the supporting force of the supporting inner pipe can be further improved, thereby more effectively strengthening the compression resistance and shock resistance of the entire double-high-beam reinforced pipe.

[0010] In the preferred embodiment, the longitudinal section of the rib pipe is in the shape of n, and the two supporting inner pipes together form the reinforcing high beam with the longitudinal section in the shape of n. The n-shaped section can effectively disperse the received pressure.

[0011] In the further preferred embodiment, the supporting inner pipe comprises a first outer wall, a second outer wall and an inner wall, the outer end of the first outer wall is connected with the outer end of the second outer wall, and the inner ends of the first outer wall and the second outer wall are respectively connected with the two ends of the inner wall; the first outer wall is in close contact with the inner wall of the rib pipe, and the first outer wall is an arc-shaped section matching the shape of the inner wall of the rib pipe, the second outer wall and the inner wall are both straight sections, and the second outer wall is perpendicular to the inner wall. The second outer wall of the two supporting inner pipes can also form the reinforcing beam perpendicular to the outer wall of the pipe body, further improving the supporting capacity.

[0012] In the further preferred embodiment, the second outer walls of the two supporting inner pipes are fused together.

[0013] The double-high-beam reinforced pipe has better compression resistance and shock resistance, is not easy to deform after being buried, and is not easy to break due to vibration. BRIEF DESCRIPTION OF DRAWINGS
