Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy construction, in particular to a pile foundation structure of water conservancy construction. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's lives and production for water resources. In water conservancy projects, pile foundations are needed to control water flow.

[0003] A Chinese utility model patent with publication number CN217710672U discloses a pile foundation structure for water conservancy construction, including a pile foundation pipe and a filling column, wherein the pile foundation pipe is provided with an inner cavity, the filling column is arranged in the inner cavity, a threaded rod is arranged in the middle of the inner cavity, and a threaded hole matching the threaded rod is arranged in the middle of the filling column; the side of the pile foundation pipe is provided with a plurality of openings, the inner wall of the pile foundation pipe is provided with a plurality of sleeves corresponding to the openings, and foot nails are arranged in the sleeves, and a spiral groove matching the foot nail is arranged on the side wall of the filling column. When working, by rotating the filling column, the threaded rod and the threaded hole are matched to make the filling column rotate upward, and the spiral groove is used to fit the foot nail to rotate, and because the spiral groove is shallower as it goes downward, the tip of the foot nail is gradually pushed out of the opening, so that it is inserted into the soil, thereby increasing the grip and stability of the pile foundation pipe.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in actual use, as the soil inside the land is subjected to increasing pressure with increasing depth, it is also compacted under the action of pressure, which can easily cause the soil near the pile foundation pipe to harden, making it difficult to insert the foot nails into the soil, resulting in poor reinforcement effect.
