The pile foundation refers to a deep foundation consisting of piles and pile bearing platforms (bearing platforms for short) connected with the pile tops or a single pile foundation connected with the pile foundation by columns, and is called the pile foundation for short. The pile foundation is an ancient foundation type. Piling technology has gone through thousands of years of development. Both pile foundation materials and pile types, or piling machinery and construction methods have been greatly developed, and modern foundation engineering systems have been formed. In some cases, the adoption of the pile foundation can greatly reduce the workload of a construction site and the consumption of materials.
However, as the number of layers of buildings is increased, the weight of the upper building is increased continuously, higher requirements are put on the bearing capacity of the pile foundation, and particularly in seashore areas or artificial islands with poor geological conditions, because the soil quality of the areas is soft, the friction force provided by the common friction piles is not enough to support the weight of the upper structure, and even if the bearing capacity requirement can be provided reluctantly, the common piles in the soft soil areas are also in danger of buckling and breaking. On the other hand, as the building increases, the possibility of horizontal load is high, bending moment is generated on the pile body, and the pile foundation is required to have strong capability of resisting the bending moment. At present, common piles cannot completely meet the requirements of modern buildings, so that a pile suitable for soft soil areas needs to be developed urgently, the bearing capacity of the pile needs to be improved, the bending resistance and the compression bending resistance of the pile need to be improved, and materials need to be saved.

In order to solve the technical problems, the utility model is realized by the following technical scheme:
a special-shaped pile foundation bearing platform structure provided with prestressed reinforcements comprises a triangular pile bearing platform, a pile body with a cross-shaped section and a reinforced concrete solid pile head. Eight steel bars exerting prestress are arranged around the pile body, a round cavity is reserved inside the pile body, and the pile head is a conical reinforced concrete block. The bearing platform, the pile body and the pile head are reliably connected through the anchoring steel bars, and enough anchoring length is reserved.
Furthermore, a reinforcement cage is arranged in the triangular bearing platform, longitudinal reinforcements of the reinforcement cage are high-strength reinforcements applied with prestress, and the prestress reinforcements are fixed through stirrups to form the reinforcement cage, so that the bearing capacity of the bearing platform is greatly improved, and the bending resistance of the bearing platform is also improved.
Furthermore, the cross-section shape of the pile body is cross-shaped, so that the friction force between pile soils is greatly improved.
Furthermore, the interior of the pile body is provided with the round cavity, the round cavity is stressed uniformly, and the using amount of concrete is saved.
Furthermore, eight prestressed reinforcements are arranged around the pile body, so that the overall rigidity of the pile is improved, and the compression, bending and bending resistance of the pile is improved.
Furthermore, the pile head is made of reinforced concrete, and Q235 steel bars are arranged inside the pile head, so that the pile body can be effectively protected.
Furthermore, anchoring steel bars are arranged between the bearing platform and the pile body and between the pile body and the pile head, so that the reliable connection between the components is ensured.
The utility model has the beneficial effects that: because the pile body is the dysmorphism cross-section, can increase the frictional force between pile body and the soil, improve the bearing capacity of stake greatly. On the other hand, the pile body is of a hollow cavity structure, so that materials can be saved, and the hollow cavity can be backfilled with backfill soil. Through the design of special-shaped cushion cap and special-shaped pile body, can improve the vertical bearing capacity of pile foundation cushion cap structure greatly, also can improve its bending resistance ability of buckling, again can save material simultaneously, be particularly useful for areas that soil layer structures such as beach, artificial island are not closely knit enough.
