Composite type supporting and retaining structure and construction method adopting supporting and retaining structure

Abstract

The invention provides a compound retaining structure, which is characterized in that it includes a reinforced concrete pile foundation, a reinforced concrete cap is placed on the top of the reinforced concrete pile foundation to form a high pile cap, and a rigid retaining wall is arranged on the reinforced concrete cap, A retaining board is provided between the reinforced concrete pile foundations. The construction method of the composite support and retaining structure is as follows: (1) excavate pile foundation holes, pour concrete to form pile foundation; (2) set caps on pile foundation; ) The retaining wall on the construction cap. The internal force and displacement of the pile foundation of this retaining structure are between buried piles and conventional high pile caps, but construction does not require deep foundation pits, so this type of support can be applied to temporary slopes with poor stability. At the same time, the retaining structure can reduce the height of the retaining wall. After the earth pressure is segmented, it can achieve the effect of reducing the total earth pressure. It also has the advantages of easy control of construction quality and beautiful effect after completion.

Description

technical field [0001] The invention relates to a retaining structure, in particular to a composite retaining structure and a construction method using the retaining structure. Background technique [0002] The retaining structure includes supporting and anchoring structures such as retaining walls, anti-slide piles, and prestressed anchor cables. Used to bear the lateral earth pressure of the soil. In the construction of water conservancy projects, traffic engineering and civil engineering, in order to ensure the safety of the project, the retaining structure must be used for reinforcement. In railway and highway subgrade projects, it is used to stabilize roadbeds, road cuttings, tunnel openings, subgrade slopes at both ends of bridges, etc. In water conservancy, mines, and housing construction projects, it is mainly used to reinforce hillsides, foundation pit slopes and river banks. . When the above projects or other geotechnical projects encounter unfavorable geologica...

AI Technical Summary

Problems solved by technology

However, in the case of a large height difference in the slope of the project, the free end of the pile foundation of the structure is too long, and the lateral deformation of the pile foundation is too large, which is not good for the safety of the pile foundation and the stability of the upper construction site
