Assembled steel corrugated pipe culvert

Abstract

The invention relates to an assembled steel corrugated pipe culvert comprising at least two pipe culvert units which are sequentially arranged in an axial direction. A corrugated plate of each pipe culvert unit is provided with an axial connecting part which is axially connected with the next pipe culvert unit. The corrugated plates of the next pipe culvert units are sequentially attached to the inner sides and the outer sides of the previous pipe culvert units. The axial connecting parts of the corrugated plates of the next pipe culvert units are sequentially arranged on the inner sides and the outer sides of the circumferential splicing double-layer parts of the previous pipe culvert units; the multiple axial splicing double-layer parts of the previous pipe culvert units sequentially form lower layer circumferential splicing three-layer parts located on the lower layers and upper layer circumferential splicing three-layer parts located on the upper layers of the axial connecting parts of the corrugated plates of the next pipe culvert units, and the lower layer circumferential splicing three-layer parts and the upper layer circumferential splicing three-layer parts are fixedly connected through bolt assemblies. According to the assembed steel corrugated steel pipe culvert, products of different sizes do not need to be produced, corrugated plates do not need to be distinguishedduring field construction, and the production and assembly construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of corrugated pipe culverts, and relates to a simple and reliable assembled steel corrugated pipe culvert. Background technique [0002] Steel bellows was first born in the UK. After more than 100 years of engineering practical application, as a typical space structure, it has gradually become a Beginning to replace traditional concrete structures and steel frame structures, it is widely used in building foundations, culverts, sidewalks, bridge and culvert repairs, flood control, urban drainage and sewage, rainwater collection and discharge, agricultural and forestry irrigation, low-pressure water supply, cable buried sheaths, fan foundations and other fields. [0003] At present, the assembly of the assembled corrugated pipe culvert in the axial direction generally adopts the method of buckling the inner and outer layers or the method of inserting and overlapping. The inner and outer layer buckle method m...

Problems solved by technology

This assembly method solves the problems of poor assembly sealing performance, rigidity and strength that exist in the inner and outer clasp method to a certain extent, but the assembly method is complicated, the construction is inconvenient, and the efficiency is relatively low.
