U-shaped assembling type double-wall corrugated closed steel corrugated culvert pipe

Abstract

A U-shaped 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; three closed double-wall corrugated pipe segments are mutually spliced to form a U-shaped 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 U-shaped pipe rings are mutually spliced to form an integral corrugated culvert pipe. The U-shaped assembling type double-wall corrugated closed steel corrugated culvert pipe has the characteristic of high strength, uniform stress and the like, as a reinforcement body of a culvert, when being compared with the reinforcement of a concrete square culvert, the U-shaped assembling type double-wall corrugated closed steel corrugated culvert pipe has the advantages of being large in sectional area and small in occupied original culvert space, is especially suitable for the reinforcement of the square culvert, can be used as a lining, 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 U-shaped 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...
