technical field

The utility model relates to the field of drainage pipes, in particular to a DRPE composite reinforced hollow winding structure wall A-type pipe for buried drainage in a Japanese shape.

Background technique

At present, the hollow winding pipe is a structural wall pipe made of high-density polyethylene as a raw material by a thermal winding molding process. It is widely used in municipal drainage, farmland water delivery and industrial sewage discharge. It can replace traditional concrete pipes and cast iron pipes. However, due to the limited external pressure that the hollow structure can withstand, it is prone to deformation. The strength of the coiled pipe in the prior art needs to be further strengthened. In addition, most of the inner walls of the existing drainage pipes are coated to achieve the effect of wear resistance, which easily causes the wear layer to fall off under the continuous action of the water flow.

As a preferred solution of the present invention, a rectangular steel strip is arranged inside the reinforcing rib.

As a preferred solution of the present invention, the outline of the skeleton is a polygon, including any one of a square, a rectangle, a hexagon, and an octagon.

As a preferred solution of the present invention, the shape of the connecting piece includes any one of a cylindrical shape, a circular truncated shape, and a stepped stage shape.

The beneficial effects of the present utility model are:

(1) In the present invention, a reinforced tensile plate is arranged on the outer wall of the A-type pipe, so that the strength of the composed pipe body is higher, and the bending resistance and bearing capacity are stronger;

(2) The setting of the wear-resistant layer effectively enhances the wear-resistant and anti-corrosion performance of the inner wall of the pipe, and improves the service life of the pipe;

(3) The reinforcing ribs arranged vertically in the cavity of the pipe and strip are beneficial to enhance the overall strength of the pipe body. The rectangular steel plate arranged inside the reinforcing ribs further enhances the firmness of the reinforcing ribs, and the connection between the reinforcing ribs and the skeleton of the pipe and strip is improved by changing the reinforcing ribs. The structure of the parts effectively enhances the structural stability of the reinforcing ribs;

(4) The wear-resistant layer and the pipe strip are integrated in the plastic extruder. During the process of winding into a pipe, the two are integrated into an integrated structure, which effectively reduces the wear-resistant layer of the pipe being washed by fluid during use. the possibility of falling off;

(5) The shape of the pipe strip is set to be square, rectangular, hexagonal and/or octagonal, and the regular geometric structure can effectively reduce the external force to a certain extent;

(6) Since the shape of the pipe and strip adopts a regular geometric shape, the contact surface between the adjacent pipe and strip after helical winding is smoother, which is conducive to the welding operation of the special polyethylene bonding material and makes the welding part more firm;

(7) Glass fiber cloth is arranged on the outer wall of the pipe layer, which further increases the strength and tensile strength of the pipe.
