Description

Technical Field

[0001] The utility model relates to the technical field of concrete square piles, in particular to a prefabricated reinforced concrete square pile with a pile tip. Background Art

[0002] Prefabricated reinforced concrete square pile is a structural element commonly used in civil engineering and construction engineering. It is usually made of prefabricated reinforced concrete and has a square cross-section. The pile tip refers to the pile tip of the prestressed pipe pile, which is used in the construction of prestressed concrete pipe pile foundations. It is used at the front end of the pipe pile and is installed on the head of the pipe pile during the sinking construction of the pipe pile to guide and block the pile. Since it is difficult to sink square piles at present, it is difficult to penetrate hard interlayers and frozen soil layers. Therefore, when prefabricating reinforced concrete square piles, pile tips are generally prefabricated at the ends to facilitate workers to sink piles.

[0003] As in the prior art, the patent with the patent authorization announcement number CN203878570U discloses a prefabricated reinforced concrete square pile with a pile tip, including a concrete square pile body, the concrete square pile body includes high-strength concrete and a steel cage arranged inside the high-strength concrete, the steel cage includes a plurality of main bars and stirrups, the main bars are arranged in the concrete square pile body along the axial direction, and at least one circle of stirrups is spirally wound around the outer periphery of the main bars; a plurality of reinforcing bars are arranged inside the steel cage, the reinforcing bars include transverse reinforcing bars and longitudinal reinforcing bars, both ends of the transverse reinforcing bars are connected to the main bars, and the longitudinal reinforcing bars are parallel to the main bars; one end of the high-strength concrete is fixedly connected with a steel pile tip. The beneficial effects of this prefabricated reinforced concrete square pile with a pile tip are: simple structure, easy to make and use, good verticality of the pile body, significantly overcome the defects of non-vertical and displacement of the pile body, reduce the damage and breakage of the pile material, and significantly improve the quality of the pile.

[0004] Although the concrete square piles in the above patent have good verticality, the existing concrete square piles are inconvenient to align when connecting the piles; when aligning the current concrete square piles, the square piles on the upper layer are first lifted by a crane, and then aligned with the square piles sunk into the ground. During the alignment process, workers are required to repeatedly calibrate manually to avoid errors, so the operation is inconvenient. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a prefabricated reinforced concrete square pile with a pile tip to solve the problems raised by the background technology and make the square pile body simpler and more convenient when connecting the piles.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a prefabricated reinforced concrete square pile with a pile tip, comprising a square pile body, the bottom of the square pile body is fixedly connected to the pile tip, the corners of the pile tip are fixedly connected to wing plates, and the top of the square pile body is provided with a docking groove matching the pile tip and the wing plate.

[0007] Furthermore, a reinforcement hole is provided at the lower end of the wing plate, a through hole matching the reinforcement hole is provided at the upper end of the square pile body, and a reinforcement column is slidably connected in the through hole.

[0008] Furthermore, the bottom and side edges of the wing plate are both chamfered.

[0009] Furthermore, a guide groove is provided at the edge of the upper end of the docking groove.

[0010] Furthermore, the height of the wing plate is smaller than the height of the pile tip.

[0011] Furthermore, the side surface of the wing plate is triangular in shape.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] This kind of prefabricated reinforced concrete square pile with a pile tip only needs to insert the pile tip and the wing plate into the docking groove when connecting the piles. Since the pile tip is conical and the docking groove matches the pile tip, the pile tip will automatically align when inserted into the docking groove, and workers do not need to perform manual calibration, making pile connection simpler and more convenient.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] See also Figure 1-2 A prefabricated reinforced concrete square pile with a pile tip comprises a square pile body 1, a pile tip 2 is fixedly connected to the bottom of the square pile body 1, a wing plate 3 is fixedly connected to the corner position of the pile tip 2, and a docking groove 5 matching the pile tip 2 and the wing plate 3 is opened on the top of the square pile body 1.

[0019] The prefabricated reinforced concrete square pile with a pile tip in the utility model only needs to insert the pile tip 2 and the wing plate 3 into the docking groove 5 when connecting the piles. Since the pile tip 2 is conical and the docking groove 5 matches the pile tip 2 and the wing plate 3, the pile tip 2 and the wing plate 3 will automatically align when inserted into the docking groove 5, and workers do not need to perform manual calibration, making the pile connection simpler and more convenient. In addition, the structure of the square pile body 1 in the utility model is similar to a prefabricated reinforced concrete square pile structure with a pile tip disclosed in the patent authorization announcement number CN203878570U, so it will not be elaborated on here.

[0020] like Figure 1 and Figure 2 As shown, a reinforcement hole 4 is formed at the lower end of the wing plate 3 , a through hole 7 matching the reinforcement hole 4 is formed at the upper end of the square pile body 1 , and a reinforcement column 8 is slidably connected in the through hole 7 .

[0021] Specifically, after the pile tip 2 and the wing plate 3 are inserted into the docking groove 5, the reinforcement column 8 can be inserted into the through hole 7 and the reinforcement hole 4 to reinforce the two square pile bodies 1 to prevent the two square pile bodies 1 from being separated and affecting the workers' welding work.

[0022] like Figure 1 and Figure 2 As shown, chamfers are provided at the bottom and sides of the wing plate 3. The chamfers will reduce the contact area between the wing plate 3 and the soil, making it easier to insert into the soil.

[0023] like Figure 1 and Figure 2 As shown, a guide groove 6 is provided at the edge of the upper end of the docking groove 5. The guide groove 6 has a guiding function, so that the wing plate 3 is more easily inserted into the docking groove 5.

[0024] like Figure 1 and Figure 2 As shown, the height of the wing plate 3 is less than the height of the pile tip 2. If the height of the wing plate 3 is not less than the height of the pile tip 2, the wing plate 3 will contact the soil earlier than the pile tip 2, which is not conducive to inserting the square pile body 1 into the soil.

[0025] like Figure 1 and Figure 2 As shown, the side of the wing plate 3 is triangular in shape. The triangular wing plate 3 has a larger contact area with the soil, and the wing plate 3 itself has a guiding function, making it easier for the square pile body 1 to be inserted into the soil in a vertical direction, thereby improving the supporting effect of the square pile body 1.

[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
