Description

Technical Field

[0001] This utility model relates to the field of foundation reinforcement technology, and in particular to a wharf foundation anti-settlement reinforcement structure. Background Technology

[0002] Foundation refers to the soil or rock layer that bears the loads of buildings, machinery, and equipment. Foundations are generally divided into two categories: natural foundations and artificial foundations. A natural foundation is one that meets the requirements of a building without artificial treatment, while an artificial foundation requires reinforcement to meet those requirements. Soil layers used as building foundations include rock, gravelly soil, sandy soil, silty soil, cohesive soil, and artificial fill. To prevent significant settlement of the wharf foundation, several foundation piles are installed. Foundation piles are vertical or inclined foundation components embedded in the soil. Their function is to penetrate weak, highly compressible soil layers or water, transferring the load borne by the piles to a harder, denser, or less compressible bearing layer.

[0003] In existing technologies, to further improve the anti-settlement effect of foundation piles, a hollow structure is set inside the pile foundation, and multiple movable rods are installed in the hollow cavity. After the pile foundation is installed inside the deep pit, the multiple rods are driven to move and insert into the inner wall of the deep pit, thereby achieving the reinforcement of the foundation pile. However, due to the limited size of the inner cavity of the foundation pile, the rods cannot be set too long, which results in insufficient insertion depth of the rods, and the stability of the foundation pile installation needs to be further improved. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing a wharf foundation anti-settlement reinforcement structure.

[0005] The technical solution of this utility model is a wharf foundation anti-settlement reinforcement structure, comprising:

[0006] The foundation pile has a hollow structure and a grouting hole is opened at the upper end of the foundation pile;

[0007] Multiple anti-settlement mechanisms are equidistantly installed on the inner side of the foundation pile. Each anti-settlement mechanism includes a threaded sleeve and multiple sets of rotating clamping assemblies. Each rotating clamping assembly includes a rod, a rotating connecting rod, a rotating seat, and an installation shaft. The rotating seat is installed on the inner wall of the foundation pile, and the installation shaft is installed on the rotating seat. A sliding hole is opened along the length of the rod, and the installation shaft is movably located inside the sliding hole. The two ends of the rotating connecting rod are rotatably connected to the rod and the threaded sleeve, respectively. Multiple vertical holes are opened on the foundation pile, and multiple vertical holes allow multiple rods to move through them.

[0008] The threaded rod is rotatably installed on the inside of the foundation pile, and multiple threaded sleeves are threadedly connected to the threaded rod.

[0009] Preferably, a small gear is provided at the top inner side of the foundation pile, and a drive shaft is installed on the small gear. The small gear is rotatably mounted on the foundation pile through the drive shaft. The drive shaft has an internal hexagonal groove, and a large gear is installed on the threaded rod. The large gear is threadedly connected to the small gear.

[0010] Preferably, a plastic film is provided on the inside of each of the multiple vertical holes.

[0011] Preferably, the end of the insertion rod is fitted with a pointed tip.

[0012] Preferably, in the initial state, the end of the insertion rod is positioned inside the corresponding vertical hole.

[0013] Preferably, both the inner and outer walls of the foundation piles are provided with anti-corrosion layers.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects: by setting the rotating insertion component, the length of the insertion rod can be greatly extended, and the insertion rod will dig a hole in the side wall of the deep pit during the rotation insertion process. When concrete is poured into the foundation pile, the concrete will enter the hole through the vertical hole, thereby further improving the anti-settlement effect of the foundation pile.

Detailed Implementation

[0019] Example 1

[0020] like Figures 1-3 As shown in the figure, the anti-settlement reinforcement structure for wharf foundation proposed in this embodiment includes a foundation pile 1, a threaded rod 2, and multiple anti-settlement mechanisms.

[0021] The foundation pile 1 has a hollow structure, and a grouting hole 102 is opened at the upper end of the foundation pile 1; both the inner and outer walls of the foundation pile 1 are provided with anti-corrosion layers.

[0022] Multiple anti-settlement mechanisms are equidistantly installed on the inner side of the foundation pile 1. Each anti-settlement mechanism includes a threaded sleeve 3 and multiple sets of rotating clamping assemblies. Each rotating clamping assembly includes a rod 4, a rotating connecting rod 5, a rotating seat 6, and an installation shaft 7. The rotating seat 6 is installed on the inner wall of the foundation pile 1, and the installation shaft 7 is installed on the rotating seat 6. A pointed tip 8 is installed at the end of the rod 4, allowing it to be easily inserted into the soil. A sliding hole 401 is formed along the length of the rod 4, and the installation shaft 7 is movably positioned inside the sliding hole 401. In the initial state, the rod... The end of 4 is set inside the corresponding vertical hole 101, and the two ends of the rotating connecting rod 5 are rotatably connected to the insertion rod 4 and the threaded sleeve 3 respectively; multiple vertical holes 101 are opened on the foundation pile 1, and multiple insertion rods 4 are allowed to pass through the multiple vertical holes 101 respectively; a plastic film 9 is provided inside the multiple vertical holes 101. The plastic film 9 is set to prevent soil scattered when the foundation pile 1 is lowered into the deep pit from entering the interior of the foundation pile 1 through the vertical holes 101; the threaded rod 2 is rotatably installed inside the foundation pile 1, and multiple threaded sleeves 3 are threadedly connected to the threaded rod 2.

[0023] The foundation pile 1 is placed into the deep pit, and the threaded rod 2 is driven to rotate. By adjusting the rotation direction of the threaded rod 2, multiple threaded sleeves 3 can be driven to move up and down synchronously. The multiple threaded sleeves 3 move upward. Since the end of the insertion rod 4 is pressed against the inside of the vertical hole 101, the insertion rod 4 cannot move upward continuously. With the cooperation of the rotating connecting rod 5, the insertion rod 4 rotates. During the rotation, the insertion rod 4 is deeply inserted into the soil, which can realize the structural reinforcement of the foundation pile 1 and improve the anti-settlement effect of the foundation pile 1. By setting the rotating insertion assembly, the length of the insertion rod 4 can be greatly extended. During the rotation and insertion process, the insertion rod 4 digs a hole in the side wall of the deep pit. When concrete is poured into the foundation pile 1, the concrete will enter the hole through the vertical hole 101, thereby further improving the anti-settlement effect of the foundation pile 1.

[0024] Example 2

[0025] like Figure 2 As shown in the figure, the anti-settlement reinforcement structure for wharf foundation proposed in this embodiment, compared with the first embodiment, has a small gear 11 installed at the top inner side of the foundation pile 1. A drive shaft 12 is installed on the small gear 11. The small gear 11 is rotatably mounted on the foundation pile 1 via the drive shaft 12. The drive shaft 12 has an internal hexagonal groove 121. A large gear 10 is installed on the threaded rod 2. The large gear 10 is threadedly connected to the small gear 11. By driving the drive shaft 12 to rotate, the small gear 11 is driven to rotate. The small gear 11 then drives the large gear 10 to rotate. The large gear 10 then drives the threaded rod 2 to rotate. The large gear 10 and small gear 11 can improve the output torque.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
