Abstract

The invention discloses a large-diameter double-wall corrugated water pipe, the pipe wall of which is composed of inner and outer layers, the inner pipe wall is smooth, the outer pipe wall is trapezoidal corrugated, and steel hoops are arranged in the cavity between the inner and outer walls. And the trapezoidal bottom groove on the outer wall is connected with the inner wall as a whole. The cavity between the inner and outer walls of the large-diameter double-wall corrugated water pipe is provided with a steel hoop, which improves the strength of the water pipe. Compared with the large-diameter steel-plastic drainage pipe commonly used in the prior art, it has light weight and low cost. The utility model has the characteristics of convenient installation and use and low production cost.

Description

Technical field: [0001] The invention relates to a pipe material, specifically a large-diameter double-wall corrugated water pipe. Background technique: [0002] In the prior art, urban drainage equipment specifically refers to the plastic winding structure developed in urban drainage pipes in recent years. Countries all over the world are scrambling to study steel-plastic drainage pipes reinforced with steel strips, which are usually rolled from strips. It is composed of the bottom, the ridge and the cap on the top of the ridge. During the rolling process, the strip is rolled in a spiral shape, and the steel strip is embedded between the ridges. The height of the top of the steel strip is similar to the top of the ridge, and finally drained The outer wall of the pipe is coated with plastic to complete the rolling of the drain pipe. This type of steel-plastic drainage pipe wall is light in weight, corrosion-resistant, and low in friction, but its strength is poor, its struc...
