Problems solved by technology

This method is difficult to construct, and it is difficult to guarantee the quality of concrete pouring, and the construction speed is also slow, especially in some karst cave areas, the concrete is easily lost into the soil (rock) cave before solidification, causing quality accidents
For some large-diameter uplift piles, there are many reinforcement configurations, and the project cost is high.
Moreover, the core concrete of the large-diameter concrete pile is basically superfluous and useless, which also causes waste of materials
[0003] Existing prefabricated pipe piles generally have a small diameter and are mechanically placed in construction, so they are difficult to apply when encountering rock layers or hard soil layers

Embodiment 1

[0044] see Figures 1 to 7 As shown in the figure, the pile strip 1 is vertically arranged on the periphery of the pipe pile, the inner side plate faces the center of the pipe pile, the adjacent left and right end faces are pressed against each other and automatically prevent inward movement, and the upper and lower end faces are pressed against each other or against each other. Tighten the anti-slip confinement ring 2; the anti-slip confinement ring 2 arranged in the horizontal direction constrains the outward movement or vertical displacement of the pile strip 1 in the horizontal and vertical directions to form a ring-shaped pile body, and a pile armor is arranged on the outside of the pile body 3. The annular pile body is arranged in the notch on the upper surface of the end pressure seat 4 and is restricted by the end pressure seat 4 to move radially outward and vertically in the horizontal direction. The outside of the pile armor 3 is the soil body of the pile hole wall 5,...

Embodiment 2

[0050] A construction method for a vertical controller for an integrated pipe pile, comprising the following steps:

[0051] The first step: at the predetermined position, use mechanical equipment to form holes in the soil of the site to form pile holes;

[0052] The second step: assemble the end pressure seat, the pile strip and the anti-slip restraint ring to form the first section, that is, the bottom section of the annular pile body, and put it into the pile hole;

[0053] Step 3: Use the vertical controller to adjust the vertical position of the first section of the annular pile body, and then continue to assemble the pile strip and the anti-slip restraint ring to form the second section of the annular pile body;

[0054] Step 4: Use the vertical controller to adjust the vertical position of the assembled annular pile, and then continue to assemble the pile strip and anti-slip restraint ring to form the third annular pile. The set elevation at which the shaped pile body ...

Embodiment 3

[0058] A construction method for a vertical controller for an integrated pipe pile, comprising the following steps:

[0059] The first step: at the predetermined position, use mechanical equipment to form holes in the soil of the site to form pile holes;

[0060] Step 2: Assemble the end pressure seat, the pile strip and the anti-slip restraint ring, and tension and lock each prefabricated member of the pipe pile to form a complete annular pile body;

[0061] The third step: use the vertical controller to adjust the vertical position of the overall annular pile body, and place the complete annular pile body into the set elevation of the pile hole;

[0062] The fourth step: constructing the pile armor, if necessary, install the pouch of the pile armor in the second step above, and grouting the pouch to form the pile armor;

[0063] Step 5: Earthwork excavation, after reaching the set elevation, fill the interior of the pipe pile with soil or construction waste as needed.

Abstract

The invention relates to the technical field of pile foundations, and discloses a vertical controller for an integrated pipe pile; the integrated pipe pile is composed of a group of prefabricated concrete components and a pile armor, and the prefabricated concrete components include pile strips, anti-slip confinement rings , End pressure seat, the pile strip is arranged vertically and circumferentially around the ring-shaped pipe pile, the end pressure seat is located at the bottom end of the integrated pipe pile, bears the end resistance, and is vertically and radially restrained and fixed to the pile strip, anti-skid The constraining ring is horizontally arranged at the upper and lower splicing positions of the pile strips and constrains the vertical and radial displacement of the pile strips. A vertical controller is arranged on the end pressure seat to control the vertical position of the pile body in the pile hole. . The vertical controller technology for the integrated pipe pile disclosed by the invention has the advantages of lower cost, convenient construction, energy saving and environmental protection, improved quality and reduced on-site manual operation, and has significant economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of pile foundations, in particular to an integrated pipe pile and a vertical controller thereof. Background technique [0002] Large-diameter piles are widely used in the foundations of buildings, bridges and large structures. At present, the construction method is mostly to form holes on site, insert reinforcement cages into the pile holes, and pour concrete on site. This method is difficult to construct, and it is difficult to ensure the quality of concrete pouring, and the construction speed is also slow, especially in some karst cave areas, the concrete is easily lost to the soil (rock) cave before solidification, resulting in quality accidents. For some large-diameter uplift piles, there are many reinforcement configurations, and the engineering cost is high. Moreover, the core concrete of large-diameter concrete piles is basically redundant and useless, which also results in a waste of materials. [...
