Steel skeleton composite pipe

Abstract

The invention is a steel frame compound pipe, which can be especially applied to water discharging pipe without internal pressure embedded underground with depth not more than 60m. The pipe wall is sandwich compound structure, the internal and the external are steel lining, between which the concrete is filled, there has localizing rib between the internal and the external linings, and the connecting surface of steel lining and concrete are arranged with nail-type rib. It has good rigidity, intensity and extensibility.

Description

technical field [0001] The steel-reinforced composite pipe is a brand-new drainage pipe culvert without internal pressure. The invention belongs to the deep-buried drainage culvert pipe without internal pressure and bears relatively high external pressure, especially for the drainage pipe without internal pressure with a buried depth of more than 60m. Background technique [0002] Buried drainage pipes without internal pressure are widely used in engineering. With the development of science and technology and the improvement of production technology, in many places where sandy materials are accumulated, it is required that the drainage pipe without internal pressure should be buried deeper and deeper. The role of drainpipes plays a vital role in engineering. For example, as one of the important production facilities of many industrial and mining enterprises, the drainage system of the tailings pond, waste residue pond or slag yard is mostly tunnels and drainage pipes and c...
