Abstract

The invention discloses a mountainous-area abutment and pier column foundation structure and a construction method thereof. The mountainous-area abutment and pier column foundation structure comprisesan expanded foundation and an anchoring body, wherein the inside of the expanded foundation is provided with a steel bar framework, one end of the anchoring body is anchored in a foundation pit of amountain body, and the lower surface of the expanded foundation is connected with the other end of the anchoring body. The technical scheme can solve the problems of difficult construction and high operation risk of an existing mountainous-area bridge pile foundation.

Description

technical field [0001] The application relates to the technical field of civil engineering, in particular to a mountain abutment and pier foundation structure and a construction method thereof. Background technique [0002] With the continuous development of my country's transportation industry, the investment in mountainous expressway construction is also increasing. Road construction mainly involves roads, bridges and tunnels, especially in areas with large differences in terrain, bridges play an irreplaceable role. [0003] In bridge engineering, the foundation is an important part of the lower structure of the bridge. It transmits the upper load to the foundation and is the main stress-bearing part of the bridge. The foundations of bridges in mountainous areas are mainly pile foundations. Due to the complex terrain in mountainous areas, especially hillsides, large machinery is difficult to construct. Pile foundations are often constructed by manual digging, but the cons...
