Technical Field
The utility model belongs to the technical field of support and relates to an anchor bolt support corrugated steel plate composite structure.
Background
The anchor bolt supporting technology is used as an active supporting technology, is applied to the reinforcing engineering of a side slope in the United kingdom for the first time in 1872, is started to be applied to the supporting of mine roadways in the United kingdom in the United states in 1918, and is continuously developed in practical engineering along with the gradual application of the anchor bolt supporting technology in various large-scale engineering constructions, such as a reinforcing arch theory, a suspension theory, a combination beam theory, an anchor bolt surrounding rock strength reinforcing theory and the like, and plays an important role in the design and application of anchor bolts. The anchor bolt supporting technology in China has been greatly developed, the supporting theory and the supporting mode are gradually improved, and the supporting level is also necessary to realize further leap.
The corrugated steel structure research in China starts later, lacks design and construction experience of a large-span and high-filling corrugated steel pipe culvert, is more complex in stress condition, is more prone to undesirable phenomena such as buckling deformation and stress concentration, and is weaker in strength and stability. Therefore, under the great background that the anchor bolt support technology is mature day by day, the anchor bolt is combined with the corrugated steel plate, surrounding rock soil is reinforced by the anchor bolt, the stability is enhanced, specific engineering requirements are met, and the application range of the anchor bolt is very important to expand.

The utility model is also characterized in that:
bolt holes are formed in the crest of the corrugated steel plate and in the end plate.
A high-strength bolt is arranged in the bolt hole.
The anchor rods are arranged along the normal direction of the profile line of the section of the corrugated steel plate.
The distance between the anchor rods is 0.5 m-3 m.
The length of the anchor rod is 1 m-5 m.
The beneficial effects of the utility model are as follows:
(1) The composite structure of the anchor bolt supporting corrugated steel plate improves the bearing capacity of the corrugated steel structure.
(2) The anchor bolt support corrugated steel plate composite structure widens the application range of the corrugated steel structure.
(3) The anchor bolt support corrugated steel plate composite structure adopts factory processing production and field assembly construction, greatly shortens the construction period, and has the advantages of light structure, simple and convenient construction and easy operation.
