Description

Pile foundation subsides and consolidates jacking leveling structure

Technical Field

The invention relates to the technical field of building facilities, in particular to a pile foundation settlement reinforcement jacking leveling structure.

Background

Before building construction, a backfill soil layer or a soft foundation with a large depth is treated, most buildings need to be driven to form a foundation under the condition that a natural foundation is not available, and then an upper building structure is constructed. Because the foundation treatment is not compact, the foundation coating has higher compressibility and insufficient foundation bearing capacity; or the underground water erosion phenomenon is formed along with the change of the drainage condition of the underground water, so that the bearing capacity of the foundation is reduced; or a weak interlayer exists between the pile end and the bedrock; or the inclination of the rock surface is large, and the side slip is caused by insufficient rock-entering depth of the pile end; or uneven settlement of the pile foundation is caused by loose soil around the pile, low soft friction coefficient and the like. Therefore, the pile foundation bearing platform needs to be jacked and leveled and the pile end bearing force layer is pressed for reinforcing, the bearing force requirement of the foundation is met or the allowable settlement deviation range is designed, the height difference between the building pile foundations is reduced, and the structural safety of a factory building is ensured.
