End-bearing pile: refers to a pile where under the action of vertical ultimate load, the top load of the pile is fully or mainly borne by the pile end resistance, and the pile side resistance is small or negligible relative to the pile end resistance.
A deep foundation that uses a caisson as the basic structure to transmit the upper load to the foundation. A caisson is a bottomless and coverless well shaft. It is generally composed of blades, feet, well wall partitions and other parts. Excavate the soil in the caisson to sink it. After reaching the design elevation, concrete bottom sealing and core filling are carried out to build the top cover to form the caisson foundation.
Features
It has a large burial depth, good integrity, good stability, a large bearing area, and can withstand large vertical and horizontal loads. The foundation is also the earth-retaining and water-retaining cofferdam structure during construction. Its construction process is simple and the technology is sound and reliable. It does not require special professional equipment and can be made into a compensating foundation to avoid excessive settlement. In deep foundations or underground structures It is widely used in industries such as bridge pier foundations, underground pump rooms, pools, oil reservoirs, mining shafts, and large equipment foundations for high-rise and super-high-rise buildings. However, the caisson foundation construction period is long, and silty and fine sand soils are prone to quicksand phenomenon when pumping water in the well, causing the caisson to tilt. The large boulder trunk or the surface of the rock layer at the bottom of the well is too tilted during the caisson sinking process. It will also bring certain difficulties to the construction.
