Embodiment Construction

[0017] As shown in Figure 1, the main body of the steel-reinforced composite pipe is composed of an outer steel lining 2, a concrete filling layer 3, and an inner steel lining 4. This structure has not only brought into play the high strength and ductility of the steel of the inner and outer steel linings, but also the rigidity of the cheap concrete, and the structural form is similar to a "sandwich". Therefore, this structural form can guarantee The steel-reinforced composite pipe works normally under the working conditions of buried depth of more than 60m and no internal pressure. In order to ensure the overall coordinated work of the product of the present invention and prevent local stability damage, certain "L", "T", "P" and other nail-shaped anchor bars 6 are arranged on the outer wall of the inner steel lining and the inner wall of the outer steel lining, and can also be used separately Arrange some "L", "T", "P" and other nail-shaped anchor bars 6 on the outer wall of ...

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...
