Steel corrugated pipe infrastructure

A basic structure and corrugated pipe technology, applied in the field of basic structure, can solve the problems that the circular section should not be fixed in the position to be placed, the large-diameter assembled structure is difficult to fix its position, and the wedge-shaped part cannot be mechanically compacted, etc., so as to shorten the construction period. Period, strong structural deformation, convenient construction effect

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.

Embodiment Construction

[0022] The present invention will be described in detail below in combination with specific embodiments.

[0023] The invention relates to a steel corrugated pipe foundation structure, which includes a foundation shell 1 of geosynthetic material, and the inside is a cavity structure. One side of the basic shell 1 is provided with a groove for placing the steel bellows 2 , and the other side is provided with protruding steps to increase the grounding area and better prevent the steel bellows 2 from moving. Filling 3 is poured into the foundation shell 1, and the filling 3 conforms to the local geological environment, has good flexibility and rigidity, and can better adapt to deformation.

[0024] The foundation shell 1 is reserved with a reserved channel 4 for passing steel bars or anchor cables, and at the same time, it is fixed at both ends of the foundation, which can increase the integrity of the foundation and make the foundation more firm.

[0025] The basic shell 1 is c...

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...
