Description

HDPE double-wall corrugated pipe

Technical Field

The utility model belongs to the technical field of corrugated pipes, and particularly relates to an HDPE double-wall corrugated pipe.

Background

The double-wall corrugated pipe is a novel light pipe made of high-density polyethylene, has the characteristics of light weight, high pressure resistance, good toughness, fast construction, long service life and the like, and has an excellent pipe wall structure design, so that the cost is greatly reduced compared with pipes of other structures. And the connection is convenient and reliable, so the connector is widely applied at home and abroad. The HDPE double-wall corrugated pipe in the prior art has limited compressive capacity, and has a complex structure after a steel mesh is added inside, so that the HDPE double-wall corrugated pipe has the defects of simple structure and strong compressive capacity.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide HDPE double-wall corrugated pipe with simple structure and strong pressure resistance.

The purpose of the utility model is realized as follows: the utility model provides a HDPE double-walled bellows, it includes the pipeline body, the pipeline body is hollow cylinder structure, the lateral surface of pipeline body is provided with the outer wall, the outer wall cover is established on the lateral surface of pipeline body, be provided with protruding screw thread on the lateral surface of outer wall, protruding screw thread winding is in the outside of outer wall, fixed connection between protruding screw thread and the outer wall, the cross sectional shape of protruding screw thread is oval-shaped half, the inside of pipeline body sets up protruding muscle, protruding muscle sets up on the medial surface of pipeline body, protruding muscle is circular, and is perpendicular with the axis of pipeline body, the medial surface of pipeline body still is provided with the splice bar, the splice bar is protruding structure, the splice bar is parallel with the axis of pipeline body.

The connecting ribs are arranged between the adjacent protruding ribs and are connected with the adjacent protruding ribs.

The raised threads are hollow.

The outer wall and the pipeline body are fixed together through gluing.

The utility model has the beneficial effects that: the pipeline has the advantages that the structure is simple, the pressure resistance is high, the outer wall is arranged on the outer side face of the pipeline body to form a double-wall corrugated pipe structure, the outer wall is provided with the raised threads, the inner side face of the pipeline body is provided with the raised ribs and the connecting ribs, the purpose of high pressure resistance is achieved through the simple structure, and other beneficial effects are detailed in the specific embodiment.
