Abstract

The invention discloses an expansion device for a culvert and a corrugated steel pipe culvert with the expansion device. The expansion device comprises two circles of coaxial reinforcing section steel, the cross section of each piece of reinforcing section steel is in an I shape, upper flange plates of the two pieces of the reinforcing section steel are covered with a circle of outer web plate, lower flange plates of the two pieces of the reinforcing section steel are covered with a circle of inner web plate, and an elastomer is fixed to the middles of web plates of the two opposite sides of the two pieces of the reinforcing section steel. The expansion device is simple in structure and convenient to install, the deformation problem of a pipe joint body can be solved, the expansion deviceis particularly suitable for a pipeline in which a corrugated steel culvert pipe is laid, so that the corrugated steel culvert pipe is more suitable for different geologies and landforms.

Description

technical field [0001] The invention relates to the technical field of engineering pipelines, in particular to an expansion device for a culvert and a steel bellows culvert with the expansion device. Background technique [0002] In the existing construction of steel corrugated culverts, when the force on the foundation is not uniform and the backfill density does not meet the standard to cause settlement, it will often cause large-area deformation (telescopic deformation) of the steel corrugated culvert, which will cause ground subsidence and make traffic The vehicle jumps during high-speed driving, causing casualties and property losses. Apparently, insufficient attention has been paid to the deformation (telescopic deformation) of the steel corrugated culvert itself, which has buried unsafe hidden dangers and needs to be resolved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an expansion device for culvert...
