Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipe construction, in particular to a splicing auxiliary device for a steel corrugated pipe culvert. Background Art

[0002] Steel corrugated culvert, also called corrugated pipe culvert, is a metal pipe-like structure made of carbon steel plate by cold forming, with a corrugated cross-section on the pipe wall and corrosion-resistant treatment on the pipe surface. It is used to replace concrete culverts and small bridges in highway and railway projects. The high-strength steel corrugated pipe with a certain flexibility not only improves the ability to adapt to the deformation of the foundation and base, and effectively solves the problem of culvert damage caused by uneven settlement of the foundation, but also the corrugated culvert has excellent force characteristics due to the existence of axial corrugations. The stress and strain caused by the load are borne axially and radially at the same time, which can disperse the effect of the load to a greater extent and better play the advantages of the steel structure. When installing and splicing the steel corrugated culvert, the connection ends of the two steel corrugated culverts are generally welded and fixed. In fact, the connection ends of the two steel corrugated culverts are manually aligned and then welded. This method cannot ensure the coaxial setting of the two corrugated pipes, which makes it impossible to align the end edges of the two steel corrugated culverts evenly, resulting in welds at the connection of the two steel corrugated culverts, which leads to poor sealing at the connection of the steel corrugated culvert.
