[0028] like Figure 1 As shown, this embodiment provides a high-water-level foundation, including a cap 2 and a plurality of piles 1. The piles 1 support the cap 2, and the load borne on the top of the cap 2 is transmitted to the soil foundation of the soil 100 through the piles 1. The piles 1 are completely driven into the soil 100, with the top of the cap 2 exposed above the soil 100. A support 3 is preferably provided between the piles 1 and the cap 2 to increase the contact area between the piles 1 and the cap 2, thereby further providing stable support for the cap 2.

[0029] The outer side of the pile body 1 is covered with a filter screen 4. The soil 100 is filtered through the filter screen 4 to prevent the soil 100 from directly contacting the outer wall of the pile body 1 and corroding the pile body 1. Groundwater can penetrate into the soil 100 and pass through the filter screen 4.

[0030] Drag-reducing slats 5 are also provided on the outside of the pile body 1 to reduce resistance when the pile body 1 is driven into the soil 100. These slats 5 are connected to the outer wall of the pile body 1 and pass through the filter screen 4. These slats 5 are preferably conical and arranged along the circumference of the pile body 1. Multiple slats 5 are provided, spaced axially along the pile body 1 to further reduce resistance when the pile body 1 is driven into the soil 100.

[0031] A water absorption structure (not shown) is provided on the drag reducing inclined plate 5. The water absorption structure includes a receiving part and a water absorption component. The receiving part is welded to the top of the drag reducing inclined plate 5, and a groove is provided on the receiving part, and the water absorption component is placed in the groove. When the pile body 1 is driven into the soil body 100, the drag reducing inclined plate 5 retains the soil and brings the water absorption component into the soil to absorb water, thereby increasing the lateral resistance of the soil body 100 and improving the overall strength, rigidity and stability of the pile body 1 and the soil body 100. The water absorption component is preferably made of cement, lime or gel material, which has a strong water absorption capacity and a fast water absorption speed, and solidifies after absorbing water, thereby improving the overall strength of the pile body 1 and the soil body 100.

[0032] Furthermore, a connecting sleeve 6 is provided at the upper end of the pile body 1, and a sealed cavity is formed between the connecting sleeve 6 and the pile body 1. A transmission hole (not shown) is provided on the pile body 1, one end of the transmission hole is connected to the sealed cavity, and the other end of the transmission hole is located on the outer wall of the pile body 1. The connecting sleeve 6 is connected to a transmission pipe 7, and the transmission pipe 7 is connected to the sealed cavity. The end of the transmission pipe 7 away from the connecting sleeve 6 can be connected to a pump to make the transmission hole in a negative pressure state, so that the water that passes through the filter screen 4 and reaches the outer wall of the pile body 1 can enter the sealed cavity through the transmission hole and finally be discharged to the ground through the transmission pipe 7, thereby preventing the pile body 1 from being corroded and achieving the effect of precipitation. In this embodiment, a connecting sleeve 6 is provided at the upper end of each pile body 1, and multiple connecting sleeves 6 are connected by one or more transmission pipes 7. The number of transmission holes, the position of each transmission hole on the pile body 1, and the extension direction can be set according to specific circumstances.

[0033] Preferably, the filter screen 4 is woven from glass fiber yarn, which is resistant to acid and alkali corrosion, has high strength, good stability and is durable. The filter screen 4 can be firmly connected to the pile body 1 by bolts.

[0034] More preferably, see Figure 2 The surface of the filter 4 is provided with an anti-corrosion layer 8 to improve the corrosion resistance of the filter 4. The anti-corrosion layer 8 can be a silicone layer, which has excellent properties such as high and low temperature resistance, oxidation resistance, corrosion resistance, electrical insulation, weather resistance, flame retardancy, hydrophobicity, non-toxicity and tastelessness, and physiological inertness, making the filter 4 durable.

[0035] In this embodiment, see Figure 3 The pile body 1 is a reinforced concrete structure, including a steel skeleton 11 and concrete poured into the steel skeleton 11, which improves the strength, rigidity and stability of the pile body 1.

[0036] Optionally, a pile head 9 is provided at the bottom of the pile body 1, and the pile body 1 contacts the soil foundation through the pile head 9. The pile head 9 can be connected to the pile body 1 by bolts.

[0037] Note that the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
