Circular assembling type double-wall corrugated closed steel corrugated culvert pipe

Abstract

A circular assembling type double-wall corrugated closed steel corrugated culvert pipe comprises closed double-wall corrugated pipe segments. Each closed double-wall corrugated pipe segment is composed of two corrugated shaped steel plates, and the two corrugated shaped steel plates are welded to form the closed double-wall corrugated pipe segment and serve as an outer wall and an inner wall of the corresponding closed double-wall corrugated pipe segment respectively; six closed double-wall corrugated pipe segments are mutually spliced to form a circular pipe ring, the outer walls and the inner walls of every two adjacent closed double-wall corrugated pipe segments are mutually spliced, and the splicing positions are fixed through a row of bolts; and multiple circular pipe rings are mutually spliced to form an integral corrugated culvert pipe. The circular assembling type double-wall corrugated closed steel corrugated culvert pipe has the characteristics of high strength, high carrying capacity and the like, and as the body of a culvert and a bridge, when being compared with a concrete pipe culvert, the circular assembling type double-wall corrugated closed steel corrugated culvert pipe has the advantages of simpleness in construction, convenience in maintenance, long in service life, high ability of adapting to the foundation deformation and the like, and is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of components for highway and railway culverts, in particular to a circular assembled double-wall corrugated closed steel corrugated culvert. Background technique [0002] Culverts are one of the important components of highway engineering. Most of the current small bridges and culverts are reinforced concrete structures. Most of these structures have various degrees of damage during use, and their adaptability to geology is poor, especially in soft soils. , Permafrost regions, the disease is particularly serious. The metal corrugated culvert structure has good adaptability to deformation and excellent mechanical properties. The culvert using flexible and high-strength steel corrugated pipe not only has good ability to adapt to the deformation of the foundation and foundation, but also can solve the problems caused by uneven settlement of the foundation. The problem of culvert damage. Due to the existence o...

AI Technical Summary

Problems solved by technology

For culverts with large spans and large depths, it is especially suitable to use assembled steel corrugated culverts, while the existing assembled circular corrugated culverts are assembled from single-wall segments, which have high filling height and load capacity. For very large culverts, its bearing capacity is poor
