Technical Field
[0001] This utility model relates to composite piles, and more particularly to a composite pile for building engineering, belonging to the field of building engineering technology. Background Technology
[0002] A pile foundation is a deep foundation in which the tops of several piles are connected by a pile cap to form a whole, jointly bearing dynamic and static loads. Piles are vertical or inclined foundation components set in the soil, their function being to penetrate soft, highly compressible soil layers or water, transferring the load borne by the piles to a harder, denser, or less compressible bearing layer. We usually refer to the piles in a pile foundation as foundation piles. Generally, when driving a foundation, multiple piles of different materials and types are combined to form composite piles. This can be used for foundation waterproofing and shaping. However, existing composite piles are not stable enough. To solve this problem…
[0003] Chinese Patent Publication No. (CN215518738U) discloses a composite pile for building construction, comprising a column pile, one end of which is provided with a connecting ring, and the other end of which is provided with a matching groove. The connecting ring and the matching groove are matched in terms of their large and small diameters. The connecting ring has a support structure inside to enhance strength. The column pile is provided with external threads. In use, one column pile in a multi-section structure is inserted into the matching groove of the next column pile through the connecting ring. When not in use, the column pile at the tail of the composite pile is connected to a sealing groove through the external threads. The support structure includes a first centrally fixed shaft located at the center of the connecting ring, and a plurality of first support rods located on the outer ring of the first centrally fixed shaft. One end of each first support rod contacts the inner ring of the connecting ring.
[0004] However, when using existing technologies to install composite piles on soft soil foundations, the compressive bearing capacity of the hollow cast-in-place concrete single-structure pile is weak. Furthermore, since the piles installed on soft soil foundations only have longitudinal bearing capacity and lack lateral support, they are prone to displacement under load. Therefore, a composite pile for building engineering is proposed. Summary of the Invention

[0028] like Figure 1-5 As shown, this utility model embodiment provides a combined pile for building engineering, including an embedded part 1, a pile body 18, and an adjustment mechanism 2;
[0029] In one embodiment, to enhance the lateral support of the embedded part 1 and the pile body 18, both the embedded part 1 and the pile body 18 are provided with a first through groove 11, and both the embedded part 1 and the pile body 18 are provided with an adjustment mechanism 2. To facilitate the fixing of the first disc 21 and the third disc 23 inside the embedded part 1, the adjustment mechanism 2 includes a support block 20 fixedly connected inside the embedded part 1. The first disc 21 and the third disc 23 are respectively fixedly connected to one side of the support block 20. To facilitate the insertion of the movable plate 24 into the soft soil foundation through the first through groove 11 to enhance the lateral support force, both the first disc 21 and the third disc 23 are provided with through holes 27. A movable plate 24 is movably connected to the third disc 23, and a fixing rod 25 is fixedly connected to one side of the movable plate 24. The other side of 4 is inserted into the first through groove 11. In order to facilitate the rotation of the second disc 22 by rotating the first rectangular rod 10, and also to facilitate the rotation of the second disc 22 to drive the fixed rod 25 to slide on the arc groove 26, thereby driving the movable plate 24 on the fixed rod 25 to move, the second disc 22 is rotatably connected inside the first disc 21. The second disc 22 has an arc groove 26. The fixed rod 25 is slidably connected to the inner wall of the arc groove 26. The first rectangular rod 10 is fixedly embedded inside the second disc 22. The second rectangular rod 13 is fixedly embedded inside the second disc 22 inside the pile body 18. The first rectangular rod 10 is rotatably connected to the embedded part 1 through the bearing. The other end of the first rectangular rod 10 is movably connected to the second rectangular rod 13.
[0030] In one embodiment, in order to facilitate the connection between the embedded part 1 and the pile body 18, and also to improve the connection strength between the embedded part 1 and the pile body 18, a first flange 12 is fixedly connected to both the embedded part 1 and the pile body 18. The first flange 12 at one adjacent end of the embedded part 1 and the pile body 18 is fixedly connected by bolts. The first flange 12 at the other end of the pile body 18 is fixedly connected to a second flange 14 by bolts. Equally spaced reinforcing ribs 19 are fixedly connected to one side of the first flange 12.
[0031] In one embodiment, in order to improve the lateral support force of the pile 18 on the soft soil foundation, and also to facilitate the rotation of the first rectangular rod 10 by rotating the second rectangular rod 13, two sets of adjustment mechanisms 2 are provided inside the pile 18. A fixing block 101 is fixedly connected to one side of the second rectangular rod 13. A slot 104 for inserting the first rectangular rod 10 is opened on the fixing block 101. Two symmetrical protrusions 102 are slidably connected inside the first rectangular rod 10. A spring 105 is fixedly connected to one end of the two protrusions 102 adjacent to each other. A groove 103 for inserting the protrusion 102 is opened on the inner side wall of the slot 104.
[0032] In one embodiment, in order to improve the stability of the movable plate 24 when it moves, a groove 29 is provided on the third disc 23, and a slider 201 is fixedly connected to one side of the movable plate 24. The slider 201 is slidably connected to the inner wall of the groove 29. In order to facilitate the rotation of the second rectangular rod 13 by rotating the second flange 14, a plurality of connecting rods 16 are fixedly connected to the inner ring of the second flange 14. One end of each of the plurality of connecting rods 16 is fixedly connected to a rod body 15, and a second through groove 17 for the insertion of the second rectangular rod 13 is provided on the rod body 15.
[0033] In one embodiment, in order to facilitate the rotation of the first rectangular rod 10, a circumferential gap is formed between the outer surfaces of the first rectangular rod 10 and the second rectangular rod 13 and the inner wall of the through hole 27. When the first rectangular rod 10 and the second rectangular rod 13 rotate around the axis, their edge movement trajectory is always located inside the through hole 27. In order to improve the corrosion resistance of the embedded part 1 and the pile body 18, the outer surfaces of the embedded part 1 and the pile body 18 are coated with an epoxy anti-corrosion coating.
[0034] In operation, the operator, based on the designed pile depth on the soft soil foundation, aligns the second rectangular rod 13 inside the pile body 18 with the first rectangular rod 10 and inserts it. This causes two symmetrical protrusions 102 inside the first rectangular rod 10 to be pressed against the inner wall of the slot 104 by a spring 105. The spring 105 then pushes the protrusions 102 into the groove 103 for fixation. Next, bolts are used to secure the embedded part 1 and the first flange 12 on the pile body 18. Since there are multiple pile bodies 18, the above operations can be performed multiple times for assembly. Finally, static pressure is used to embed the connected embedded part 1 and pile body 18 into the soft soil foundation. A socket wrench is then inserted into the second rectangular rod 13. Turning the wrench clockwise causes the second disc 22 to rotate on the first disc 21, while simultaneously causing the fixed rod 25 to slide along the arc groove 26. This allows the movable plate 24 on the fixed rod 25 to move on the third disc 23. Through the through grooves provided on the embedded part 1 and the pile body 18, the movable plate 24 can pass through the through grooves and be inserted into the soft soil foundation for lateral support. Then, the second through groove 17 provided on the second flange 14 is aligned with the second rectangular rod 13 and inserted. The second flange 14 and the first flange 12 are then fastened with bolts, further fixing the movable plate 24 inserted into the soft soil foundation. Finally, by pouring concrete into the pile body 18, the compressive strength and lateral support of the pile body 18 can be improved.
[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
