Abstract

The invention discloses a corrugated pipe culvert structure. The corrugated pipe culvert is formed by sequentially connecting at least two layers of corrugated pipes in a sleeved mode. In the at leasttwo layers of corrugated pipes, the stripe directions of at least two adjacent layers of corrugated pipes are different, the stripe directions of the corrugated pipes take convex points on the outersides of the corrugated pipe bodies as wave crests and take convex points on the inner sides of the pipe bodies as wave troughs, and the wrinkle stripes formed between the wave crests and the wave troughs are extensible, and the extension direction is called as the stripe direction. According to the invention, a multi-layer corrugated pipe structure design is adopted; the stripe directions of theadjacent corrugated pipes are different; the formed pipe body is rigid in the circumferential direction and the axial direction; the characteristic of weak transverse stability of the one-way steel corrugated pipe culvert is overcome; the overall anti-pressure ability of the corrugated pipe culvert is improved; the characteristic that all layers of steel corrugated pipes are flexible in one direction and easy to construct and assemble can be brought into play during construction; a large number of construction auxiliary rib positioning measures can be omitted, excessive development of plastichinges in the construction process can also be omitted, the implementation progress is fast, and a two-way rigid steel corrugated pipe whole is formed after construction is completed.

Description

technical field [0001] The invention belongs to the technical field of bridge and culvert engineering, and particularly relates to a corrugated pipe culvert structure suitable for municipal, highway, railway and water conservancy drainage culverts or pedestrian passage culverts. Background technique [0002] With the continuous improvement of the level of engineering construction, the culverts and passages of traditional reinforced concrete structures used in various construction projects are not only inconvenient to control the construction quality, but also have a long time for on-site construction operations, a large workload, and a large labor demand. As a new type of culvert, the steel bellows culvert is mainly composed of corrugated pipes made of steel, aluminum and other materials. It has the characteristics of good mechanical characteristics, greater concentration and dispersion of load stress, and the construction period Short length, light weight, easy installation...
