Steel corrugated pipe infrastructure

Abstract

The invention relates to a steel corrugated pipe infrastructure. The steel corrugated pipe infrastructure comprises a base shell provided with a cavity, one side of the base shell is provided with a groove accommodating a steel corrugated pipe, and the other side of the base shell is provided with protruded steps; the base shell is internally perfused with filler. The steel corrugated pipe infrastructure can practically and feasibly ameliorate the position fixing problem when the steel corrugated pipe is constructed, has the advantages of being low in weight, high in strength, low in cost, convenient in construction, high in construction speed and the like, and compared with manual tamping after soil is filled, basic compactness can be better guaranteed; the steel corrugated pipe infrastructure can be widely applied in the constructing process of a highway steel corrugated pipe culvert, and a positive effect is bound to be exerted on the development and the popularization of the steel corrugated pipe infrastructure.

Description

technical field [0001] The invention relates to a basic structure, in particular to a steel bellows basic structure. Background technique [0002] With the development of the economy, my country's infrastructure construction is in full swing, and highways are projects that have been heavily invested in infrastructure construction. A large number of culverts are used in road construction. With the use of steel in recent years, most culverts have chosen steel bellows to replace the past reinforced concrete structure. However, the position fixation and foundation compaction of steel bellows have always been a difficult problem affecting its popularization and application. During the construction of the steel bellows, because its circular cross-section is not suitable to be fixed at the desired position, it will often be misplaced during construction, especially for large-aperture assembled structures. It is more difficult to fix its position. At present, wood or stones are m...

AI Technical Summary

Problems solved by technology

However, the position fixation and foundation compaction of steel bellows have always been a problem that affects its popularization and application.

During the construction of the steel bellows, because its circular cross-section is not suitable to be fixed at the position to be placed, the position often shifts during construction, especially the large-aperture assembled structure is more difficult to fix its position

At present, wood or stones are mainly used to fix it simply, and it often moves during construction. At the same time, the wedge-shaped part at the bottom of the pipe cannot be compacted mechanically, and it is difficult to ensure its compactness by artificial filling.
