Description

Technical Field

[0001] This application relates to the field of municipal building materials technology, and in particular to a precast pipe pile for municipal construction. Background Technology

[0002] In the field of municipal construction engineering, precast pipe piles are widely used in various foundation projects. They are usually hollow cylindrical tubular structures. Precast pipe piles need to be spliced ​​on the construction site to ensure that the length of the pipe piles meets the design requirements. At the same time, it is necessary to ensure that the quality of the pipe piles is stable, the strength is high, and the durability is good.

[0003] Chinese utility model patent CN222375391U discloses a precast pipe pile for municipal construction, comprising a cement pile. Connecting blocks are fixedly installed at both ends of the cement pile. Two sets of connecting grooves are symmetrically formed on the end of each connecting block away from the cement pile. Connecting arc plates are respectively provided on each connecting groove, with the height of the arc plates being twice the depth of the groove. The two sets of connecting arc plates can be connected by a side-locking component. A positioning groove is formed on one end of each connecting block. The positioning groove is trapezoidal in shape and gradually narrows from the side away from the cement pile to the side closer to the cement pile. A positioning block is fixedly installed on the other end of the connecting block. The positioning block is trapezoidal in shape, and its size is adapted to the size of the positioning groove. In this utility model, the side-locking component provides strong lateral constraint for the connection of the cement pile, forming a stable lateral connection structure and effectively ensuring the overall stability of the pipe pile under complex lateral stress environments.

[0004] In actual use, during pile splicing operations, another set of cement piles is suspended above the cement piles that have already been inserted into the ground using pile drivers and other equipment. Because the cement piles are suspended, they are prone to shaking. The positioning groove and positioning block on the bottom connecting block of the upper cement pile are not easy to be firmly positioned with the positioning block and positioning groove on the top connecting block of the lower cement pile. The easily shaking cement piles make it difficult to install and fix the precast piles as a whole. Utility Model Content

[0005] To facilitate the splicing and installation of piles and make the overall installation and fixing of precast piles convenient, this application provides a precast pipe pile for municipal construction.

[0006] This application provides a precast pipe pile for municipal construction, which adopts the following technical solution:

[0007] A precast pipe pile for municipal construction includes at least one set of pile columns. One end of each pile column is provided with a ring block, and the other end is provided with a ring groove. The ring block matches the ring groove, and the ring groove is for the ring block to be inserted. Two sets of pile columns are connected and fixed by the insertion of the ring block and the ring groove. The pile column also includes a fixing component for fixing the two sets of pile columns.

[0008] By adopting the above technical solution, the ring block at one end of the pile column is directly inserted into the ground. When the pile column needs to be spliced, a ring groove is opened at one end of the pile column, and the ring block set on the other pile column is inserted into the ring groove. The two sets of pile columns are easy to install and position. The insertion and cooperation of the ring groove and the ring block makes the pile column less prone to shaking, and the ring groove and the ring block are not easy to separate. It is easy to splice and install the pile column, and the precast pile is easy to install and fix as a whole.

[0009] Optionally, limit blocks are provided on opposite sides of the bottom of the annular groove, and the annular blocks are provided with limit grooves for the limit blocks to be accommodated.

[0010] By adopting the above technical solution, the ring block can be easily engaged in the ring groove through the limiting block and the limiting groove, thus restricting the rotation of the ring block.

[0011] Optionally, the fixing component includes a first arc-shaped block, a second arc-shaped block, and two fixing bolts. The side surface of the pile column has receiving grooves on both sides for the first arc-shaped block and the second arc-shaped block to pass through. The first arc-shaped block has through holes on both sides for the fixing bolts to pass through. The through holes are connected to the limiting block. The ring block has connecting holes for the fixing bolts to pass through. The second arc-shaped block has threaded holes on both sides. When the ring block is inserted into the ring groove, the fixing bolts pass through the through holes and connecting holes and are threaded into the threaded holes.

[0012] By adopting the above technical solution, after the ring block is inserted into the ring groove, the first arc-shaped block and the second arc-shaped block are inserted together. The first arc-shaped block and the second arc-shaped block pass through the receiving groove. Threaded holes are opened on both sides of the second arc-shaped block. The fixing bolt passes through the through hole and the connecting hole and is threaded into the threaded hole. While fixing the two sets of piles, the first arc-shaped block and the second arc-shaped block are threadedly connected and fixed. When the fixing bolt is removed, the first arc-shaped block and the second arc-shaped block are separated. The first arc-shaped block and the second arc-shaped block do not need to fix the two sets of piles separately, which ensures that the two sets of piles are firm while facilitating the assembly and disassembly of the first arc-shaped block and the second arc-shaped block.

[0013] Optionally, the ring block is provided with a mounting groove for accommodating the first arc-shaped block and the second arc-shaped block, the first arc-shaped block and the second arc-shaped block passing through the accommodating groove and being engaged in the mounting groove.

[0014] By adopting the above technical solution, the first arc-shaped block and the second arc-shaped block are engaged in the installation groove, which further prevents the two sets of piles from separating and improves the stability of the pile connection.

[0015] Optionally, the pile tip segment is included, wherein the structure of the end of the pile tip segment near the ring block is the same as the structure of the end of the pile column away from the ring block, the ring block is inserted into the end of the pile tip segment away from the tip, and the pile tip segment and the pile column are fixed by a fixing component.

[0016] By adopting the above technical solution, the pile tip section facilitates the insertion of the pile tip into the ground during pile installation, ensuring a firm insertion of the pile.

[0017] Optionally, the limiting block is provided with rounded corners.

[0018] By adopting the above technical solution, the rounded corners facilitate the insertion of the limiting groove and the limiting block.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. The ring block is inserted into the ring groove, making the pile column less prone to shaking. At the same time, the ring groove and the ring block are not easily separated, which facilitates the installation of the pile column and makes the overall installation and fixing of the precast pile convenient.

[0021] 2. The limiting block and limiting groove restrict the rotation of the ring block, making it easy to position;

[0022] 3. Two sets of piles are fixed by fixing bolts. The first arc-shaped block and the second arc-shaped block are fixed by threaded connection. The first arc-shaped block and the second arc-shaped block do not need to be fixed to the two sets of piles separately, which facilitates the assembly and disassembly of the first arc-shaped block and the second arc-shaped block.
