Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of prestressed pipe piles with enhanced bearing capacity, in particular to a prestressed pipe pile with enhanced bearing capacity. Background Art
[0002] PHC piles, or prestressed high-strength concrete piles, are made using a pre-tensioned prestressed centrifugal forming process and are cured by steam at 10 atmospheres (about 1.0Mpa) and 180°C to form a hollow cylindrical precast concrete component with a standard section length of 10m, a diameter of 300mm to 800mm, and a concrete strength grade of ≥C80.
[0003] When a single section of pipe piles cannot reach the length specified in the design, multiple sections of pipe piles need to be spliced together to meet the demand. In order to ensure the bearing capacity of the pipe piles after splicing and avoid the pipe piles from breaking due to position deviation during piling, workers are usually required to align the connection parts of the two pipe piles and then weld them together. When welding current pipe piles, workers usually need to frequently adjust the position of the pipe piles to keep them aligned, which affects work efficiency. In addition, after all the pipe piles are installed, mud and debris enter the pipe piles, requiring workers to dig out the core before later core filling, which increases the work intensity of the workers.
[0004] Therefore, we made improvements to this and proposed a prestressed pipe pile with enhanced bearing capacity. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:
[0006] The cam is provided with a first end fixedly mounted on the bottom end of the support frame, and the second end of the first end is connected with a second end of the support frame to form a circle, and the cam is provided with a second end fixedly mounted on the bottom end of the support frame.
[0007] As a preferred technical solution of the utility model, the size of the arc-shaped positioning block matches the size of the second sliding groove.
[0008] As a preferred technical solution of the utility model, the size of the arc-shaped clamping block matches the size of the arc-shaped clamping slot.
[0009] As a preferred technical solution of the utility model, a knob is installed on the top of the protective cover.
[0010] As a preferred technical solution of the utility model, reinforcing ribs are installed inside the pipe pile body.
[0011] As a preferred technical solution of the utility model, the surfaces of the lower connecting plate and the upper connecting plate are both provided with an anti-rust layer.
[0012] The beneficial effects of the utility model are:
[0013] 1. The prestressed pipe pile with enhanced bearing capacity in the utility model is convenient for workers to quickly align the connection points of two different pipe piles through the coordinated use of the lower connecting plate, the first sliding groove, the first sliding block, the arc-shaped positioning block, the upper connecting plate, the second sliding groove and the compression spring, thereby improving the working efficiency when splicing the pipe piles;
[0014] 2. The prestressed pipe pile with enhanced bearing capacity in the utility model is convenient for covering the top of the pipe pile after the installation of the pipe pile is completed by using the protective cover, the second slider, the arc-shaped clamping block, the second slide groove and the arc-shaped clamping groove to prevent mud and sand from entering the interior of the pipe pile and requiring core digging work at a later time, thereby reducing the work intensity of the staff and reducing labor costs.

DETAILED DESCRIPTION
[0021] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.
[0022] Example: Figure 1-4 As shown, the prestressed pipe pile with enhanced bearing capacity of the utility model comprises a pipe pile body 1, a lower connecting plate 2 is installed at the bottom end of the pipe pile body 1, a pair of first slide grooves 3 are symmetrically arranged on both sides of the bottom end of the lower connecting plate 2, a first slider 4 is slidably installed in the first slide groove 3, a plurality of compression springs 5 are installed at the top end of the first slider 4, and the other end of the compression spring 5 is connected to the top end of the first slide groove 3, an arc-shaped positioning block 6 is installed at the bottom end of the first slider 4, and the arc-shaped positioning block 6 extends to the outside of the lower connecting plate 2, an upper connecting plate 7 is installed at the top end of the pipe pile body 1, a pair of second slide grooves 8 are symmetrically arranged on both sides of the top end of the upper connecting plate 7, an arc-shaped clamping groove 9 is arranged on one side of the second slide groove 8, a protective cover 10 is installed at the top end of the upper connecting plate 7, a second slider 11 is installed at the bottom end of the protective cover 10, and the second slider 11 is slidably connected to the second slide groove 8, and an arc-shaped clamping block 12 is installed on one side of the second slider 11.
[0023] Among them, the size of the arc-shaped positioning block 6 matches the size of the second slide groove 8. After the staff roughly aligns the positions of the two pipe pile bodies 1, they adjust the position of the pipe pile body 1 by translation and rotation. When the arc-shaped positioning block 6 moves to the vicinity of the second slide groove 8, the compression spring 5 pushes the arc-shaped positioning block 6 downward, so that the arc-shaped positioning block 6 enters the second slide groove 8, thereby realizing the alignment of the positions of the two pipe pile bodies 1, improving the alignment efficiency, and facilitating subsequent welding work.
[0024] The size of the arc-shaped clamping block 12 matches the size of the arc-shaped clamping slot 9 , and the protective cover 10 is fixed to the top of the upper connecting plate 7 by screwing the arc-shaped clamping block 12 into the arc-shaped clamping slot 9 .
[0025] A knob 13 is installed at the top of the protective cover 10 to facilitate the rotation of the protective cover 10 .
[0026] Among them, reinforcing ribs 14 are installed inside the pipe pile body 1 to improve the overall bearing capacity of the pipe pile body 1.
[0027] The surfaces of the lower connecting plate 2 and the upper connecting plate 7 are both provided with an anti-rust layer to reduce the damage caused by rust to the lower connecting plate 2 and the upper connecting plate 7 during long-term use.
[0028] Working principle: When using this type of prestressed pipe pile with enhanced bearing capacity, the staff first installs the conical head at the bottom end of the pipe pile body 1 at the bottom to facilitate inserting the pipe pile into the soil. When the length of the single-section pipe pile is not enough, the staff first aligns the positions of the two pipe pile bodies 1 roughly, and adjusts the position of the pipe pile body 1 by translation and rotation. When the arc-shaped positioning block 6 moves to the vicinity of the second slide groove 8, the compression spring 5 pushes the arc-shaped positioning block 6 downward, so that the arc-shaped positioning block 6 enters the second slide groove 8, thereby realizing the alignment of the positions of the two pipe pile bodies 1, which is convenient for subsequent welding work. When the pipe piles are all installed, the staff aligns the protective cover 10 with the position of the top of the upper connecting plate 7, so that the second slider 11 enters the second slide groove 8, and by rotating the knob 13, the arc-shaped block 12 enters the arc-shaped slot 9, so as to fix the protective cover 10 on the top of the upper connecting plate 7 to prevent soil and debris from entering the interior of the pipe pile body 1.
