Technical Field

[0002] Foundation pit support refers to the support, reinforcement and protection measures taken for the side walls of the foundation pit and the surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. The main purpose of foundation pit support is to ensure the stability of the slope during the excavation of the foundation pit, prevent the surrounding soil and structures from becoming unstable or collapsing due to excessive deformation, and ensure the safety and smooth progress of operations in the foundation pit. In actual projects, there are various forms of foundation pit support, such as cast-in-place piles, anchor piles, internal supports, mixing piles, steel supports, retaining walls, soil nail walls, continuous walls, water-blocking curtains, combined steel sheet piles, etc., which can be selected and designed according to the geological conditions, environmental conditions, construction conditions and other factors of the specific project. At the same time, the design of foundation pit support should meet the requirements of stability and deformation, ensuring the safety of the support structure and controlling its impact on the surrounding environment.
