Description

Inclined pile for building foundation pit support

technical field

The utility model relates to the technical field of inclined piles for foundation pits, in particular to an inclined pile for building foundation pit support.

Background technique

The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. The support, reinforcement and protection measures are adopted for the side wall of the foundation pit and the surrounding environment. The difference between the inclined pile and the ordinary pile is that the inclined pile is not Drill holes perpendicular to the horizontal plane to form piles, but have a certain angle with the vertical line of the horizontal plane. Since the inclined piles are not perpendicular to the horizontal plane, the self-weight of the hole wall, steel cage and concrete should be considered in the design and construction. Under the same external load, the axial force suffered is greater than that of vertical piles, while the lateral force is smaller than that of vertical piles. After analysis and demonstration, the inclined piles arranged in a figure-eight shape constitute a unique three-dimensional space system and the piles formed The force of the foundation is similar to the root system of trees in nature, and it is especially suitable for the force characteristics of the structural foundation that not only bears the pressure but also bears the uplift force and horizontal force generated by the horizontal wind force.
