Description

Technical Field

[0001] The utility model relates to a self-anchoring micro steel pipe pile, in particular to a self-anchoring micro steel pipe pile, belonging to the technical field of micro piles. Background Art

[0002] Micro piles refer to tree root piles, precast concrete piles or steel pipe piles with a diameter not exceeding 300 mm formed in the soil by pile-driving machinery or other small equipment.

[0003] The micro piles in this code are piles with a cross-sectional diameter or side length not exceeding 300mm formed by the cross-sectional area of ​​the pile body implanted, driven or pressed into the natural foundation soil or the vertical reinforcement of the foundation soil.

[0004] When implanting the micro pile into the ground, the micro pile is placed perpendicular to the ground and sunk so that the steel pipe body is inserted into the ground. However, in the prior art, the micro pile cannot be guaranteed to be in a vertical state during the sinking of the micro pile. During the sinking process, the micro pile may be skewed, resulting in the micro pile driven into the ground not being in a vertical state. There is a certain deviation, and the effect is poor. At the same time, the micro pile needs to be constantly adjusted during the sinking process. Therefore, we propose a self-anchoring micro steel pipe pile. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model discloses a self-anchoring micro steel pipe pile.

[0023] According to the attached Figure 1-4As shown, it includes a micro steel tube body 1, and a plurality of grouting holes are formed on the micro steel tube body 1. Cement slurry is injected into the micro steel tube body 1 and the ground through the grouting holes, so that the micro steel tube body 1 can be supported by the slurry. A socket 2 is sleeved on the outer peripheral wall of the micro steel tube body 1, and a plurality of telescopic rods 201 are fixedly connected between adjacent sockets 2. The socket 2 is provided with:

[0024] The support unit includes a threaded rod 3 and a sliding rod 301. The threaded rod 3 is rotatably connected to one of the socket seats 2. The threaded rod 3 is slidably connected to the sliding rod 301. The support unit supports the socket seat 2 through the threaded rod 3 and the sliding rod 301. The threaded rod 3 and the sliding rod 301 are connected to the ground to support the socket seat 2. The horizontal angle of the socket seat 2 is adjusted by adjusting the sliding of the sliding rod 301 and the threaded rod 3, so that the socket seat 2 is in a horizontal position.

[0025] An adjusting unit includes a pushing seat 4, which is slidably connected to the inner wall of the socket 2. The pushing seat 4 fits the micro steel tube body 1. The adjusting unit is used to adjust the position of the micro steel tube body 1. The micro steel tube body 1 is inserted into the ground through the socket 2, and the micro steel tube body 1 is squeezed by adjusting the pushing seat 4 to adjust the position of the micro steel tube body 1. The micro steel tube body 1 is adjusted to be in a vertical state, which is convenient for supporting the micro steel tube body 1 and makes the micro steel tube body 1 sunk into the ground in a vertical state. The effect is better and it is avoided to constantly adjust the position of the micro steel tube body 1 during the pile sinking process.

[0026] A plurality of connection seats 302 are rotatably connected to the inner wall of the socket seat 2. The connection seats 302 are fixedly connected to the ends of the threaded rods 3. The connection seats 302 are rotated on the socket seat 2 to adjust the angle between the threaded rods 3 and the socket seat 2.

[0027] The outer wall of the threaded rod 3 is threadedly connected with an adjusting nut 303, and the adjusting nut 303 is rotatably connected to the outer wall of the sliding rod 301. By rotating the adjusting nut 303, the sliding rod 301 is driven to rotate along the outer wall of the threaded rod 3, so that the sliding rod 301 drives the threaded rod 3 to move, pulls the socket 2 to move, and changes the angle of the socket 2. By adjusting multiple threaded rods 3, the socket 2 is in a horizontal position.

[0028] The bottom end surface of the sliding rod 301 is rotatably connected with the positioning rod 5. By plugging the positioning rod 5 into the ground, the sliding rod 301 and the threaded rod 3 are plugged into the ground.

[0029] A screw rod 401 is threadedly connected to the inner wall of the socket 2 .

[0030] One end of the screw rod 401 is rotatably connected to the pushing seat 4. By rotating the screw rod 401, the screw rod 401 is driven to rotate along the socket seat 2. At this time, under the movement of the screw rod 401, the pushing seat 4 is pushed to slide on the inner wall of the socket seat 2, so that the pushing seat 4 pushes the micro steel pipe body 1. At this time, under the push of the pushing seat 4, the position of the micro steel pipe body 1 is adjusted to facilitate the adjustment of the micro steel pipe body 1 to a vertical state, which is convenient for subsequent pressure, so that the micro steel pipe body 1 enters the ground, and then facilitates subsequent grouting.

[0031] The other end of the screw rod 401 penetrates the socket 2 and extends outward. One end of the screw rod 401 outside the socket 2 is fixedly connected to an adjustment handle 402. The screw rod 401 is rotated by rotating the adjustment handle 402.

[0032] Working principle: First, the positioning rod 5 is inserted into the ground, so that the sliding rod 301 and the threaded rod 3 are inserted into the ground;

[0033] At this time, the micro steel tube body 1 is inserted into the socket 2, and the sliding rod 301 is driven to rotate along the outer peripheral wall of the threaded rod 3 by rotating the adjusting nut 303, so that the sliding rod 301 drives the threaded rod 3 to move, pulls the socket 2 to move, changes the angle of the socket 2, and adjusts the plurality of threaded rods 3 so that the socket 2 is in a horizontal position;

[0034] The screw rod 401 is driven to rotate by rotating the adjusting handle 402. As the screw rod 401 rotates, the screw rod 401 is driven to rotate along the socket seat 2. At this time, as the screw rod 401 moves, the push seat 4 is pushed to slide on the inner wall of the socket seat 2.

[0035] The pushing seat 4 pushes the micro steel pipe body 1. At this time, under the push of the pushing seat 4, the position of the micro steel pipe body 1 is adjusted to facilitate the adjustment of the micro steel pipe body 1 to a vertical state, which is convenient for subsequent pressure, so that the micro steel pipe body 1 enters the ground, and then facilitates subsequent grouting.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
