Description

Technical Field

[0001] This utility model relates to the field of pile foundation technology, specifically a pile foundation structure. Background Technology

[0002] A pile foundation is a deep foundation consisting of piles and a pile cap (or simply pile cap) connecting the pile tops, or a single pile foundation connecting a column and the pile foundation. Pile foundations are mainly divided into two categories: According to the height of the pile cap: Low-pile-cap pile foundation: The entire pile body is buried in the soil, and the bottom surface of the pile cap is in contact with the soil. Building pile foundations are usually low-pile-cap pile foundations, and they are widely used in high-rise buildings. High-pile-cap pile foundation: The upper part of the pile body is exposed above the ground, while the bottom of the pile cap is above the ground. Its stress and deformation differ from low-pile-cap pile foundations. They are generally used in bridge and wharf projects. According to the force principle: Friction piles: These utilize the friction between the soil and the pile to support the structure. They can be divided into pressure piles and tension piles, and are generally used when there is no hard bearing layer or the bearing layer is deep. End-bearing piles: These allow the pile to rest on the bearing layer (rock bed) to support the structure. The construction methods for pile foundations mainly include precast piles and cast-in-place piles: Precast piles: Precast reinforced concrete piles are driven into the ground using a pile driver. Advantages include material savings, high strength, and suitability for buildings with high requirements. However, construction is difficult, limited by the number of machines, and time-consuming. Cast-in-place piles: Holes are drilled on the construction site, and once the required depth is reached, reinforcing steel is inserted and concrete is poured. Advantages include low construction difficulty, especially manually excavated piles, which are not limited by the number of machines and can be constructed simultaneously, greatly saving time. However, they have lower bearing capacity and consume more materials. There are many types of pile foundations, including stone piles, sand piles, gravel piles, wooden piles, lime-cinder piles, steel piles, ordinary reinforced concrete piles, and compacted concrete piles (DDC). Furthermore, pile foundations exhibit small deformation and good stability under seismic forces, making them an effective measure for addressing seismic resistance issues in weak and liquefiable foundations in earthquake-prone areas.

[0003] According to patent number CN213062074U published on the China Patent Network, this utility model provides a pile foundation structure suitable for embedding in soil, comprising: several composite piles, adjacent composite piles spaced apart, each including a pile core and an outer pile surrounding the pile core; and an overlapping structure, disposed between adjacent composite piles, fitting snugly against the composite piles, with the embedment length of the overlapping structure gradually decreasing along the direction away from the composite piles. By gradually reducing the embedment length of the overlapping structure along the direction away from the composite piles, the horizontal resistance performance of the soil around the composite piles can be fully utilized while ensuring that the horizontal bearing capacity of the composite piles meets the usage requirements. In addition, by reducing the embedment length of the overlapping structure, the material consumption of the overlapping structure is correspondingly reduced, the construction period is shortened, and the construction efficiency is improved, overcoming the shortcomings of existing technologies where overlapping piles between composite piles require more material and have higher costs.

[0004] The installation of load-bearing platforms requires the use of pile foundations. However, most pile foundations on the market are usually fixed, which makes it impossible to quickly adjust the length of the pile foundation. It is necessary to extend the pile foundation by splicing with bolts, which is time-consuming and laborious, and does not bring convenience to users, thus affecting the normal use of the pile foundation.

[0005] Therefore, it is necessary to design and modify the pile foundation to effectively prevent the phenomenon that the length of the pile foundation cannot be quickly adjusted. Utility Model Content
