Description

Technical Field

[0001] The utility model relates to the technical field of under-reamed piles, and particularly to an under-reamed pile for building foundation construction. Background Technique

[0002] The building foundation is one of the most crucial parts of the building structure. It transfers the load of the building to the foundation and ensures the stability and safety of the entire building. The design and construction of the foundation need to comprehensively consider factors such as geological conditions, load characteristics, and the usage requirements of the building. The under-reamed pile (also known as under-reamed pile foundation or pile foundation under-reaming) is a special type of pile foundation. It expands into a larger bottom area at the bottom or around part of the pile body to improve the bearing capacity and stability of the pile, and is commonly used in low-rise buildings or walls that bear relatively light loads;

[0003] After retrieval, the Chinese patent with the publication number: CN212026221U discloses an under-reamed pile for building foundation construction. It is recorded in this patent that a pouring groove is opened at the top end of the outer sleeve rod, the inner wall of the pouring groove is fixedly connected with the bottom end of the support pile, the bottom end of the outer sleeve rod is fixedly connected with the top of the under-reamed base, the inner wall of the top of the under-reamed base is fixedly connected with the top end of the central rod, a base is arranged at the bottom of the central rod, and an avoidance groove is opened in the middle of the base. For this under-reamed pile for building foundation construction, by adopting the under-reamed base as a hemispherical shell structure, the material used for the under-reamed pile for building foundation construction is reduced, and the cost of the under-reamed pile for building foundation construction is lowered. Through the cooperation of the central rod and the auxiliary rod with the under-reamed base, the top support capacity of the under-reamed base is relatively strong, the risk of deformation of the top of the under-reamed base under external force is reduced, and the service life of the under-reamed pile for building foundation construction is improved.

[0004] The equipment in this scheme cannot effectively disperse the load, resulting in excessive pressure in some places, thereby increasing the risk of foundation damage. If the equipment cannot maintain an accurate position during the construction process, it will cause the construction of the foundation not to meet the design requirements, which will affect the structural stability of the entire building. To solve this technical problem, the utility model proposes an under-reamed pile for building foundation construction. Summary of the Invention

[0025] Example 1: A under-reamed pile for building foundation construction, including an under-reamed base 1. The under-reamed base 1, as the main load-bearing part of the foundation, is located at the bottom of the foundation construction. Its design goal is to increase the foundation contact area through the under-reamed pile and improve the bearing capacity. A support pile 7 is fixedly connected to the top of the under-reamed base 1.
