[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figures 1-3 This utility model provides a guide wall technical solution for composite interlocking piles under ultra-thick rock geological conditions: including a guide wall body 11, installation holes 12, installation piles 13, positioning holes 14, rotating holes 15, etc.
[0022] Installation pile 13: Installed at the bottom of the guide wall body 11.
[0023] Mounting holes 12: There are several holes that penetrate the guide wall body 11, one of which extends from the guide wall body 11 to the installation pile 13.
[0024] Positioning holes 14 and rotating holes 15: Several of them, arranged in two columns according to a set pattern.
[0025] Guide rods 2 are installed on the positioning holes 14 and 15 using hardware components. The guide rods 2 have plain pile positioning holes 21 and concrete pile positioning holes 22. Furthermore, the guide rods 2 can be made of wood or plastic. During construction, an existing laser vertical positioning module is installed on the existing rotary drilling machine, enabling the machine to accurately locate the center coordinates of the plain pile positioning holes 21 and complete the operation. The guide rods 2 can be rotary-cut together during operation. After the foundation treatment is completed, new guide rods 2 can be replaced. Preferably, the guide rods are divided into two groups: one group is thinned in the upper half, and the other group is thinned in the lower half; the two groups are staggered on the guide wall body. This allows the guide rods 2 to be staggered after selection, thereby enabling the two concrete pile positioning holes 22 to overlap.
[0026] The positioning hole 14 is designed to be hexagonal. In one embodiment, after the hexagonal positioning pin in the hardware component is inserted, the guide rod 2 can be fixed on the guide wall body 11 to prevent the guide rod 2 from shaking during the positioning process.
[0027] The adjacent guide rods are parallel to each other and equidistant. This ensures that each solid pile is also equidistant.
[0028] In one embodiment, installation is performed through the following steps:
[0029] Step 1: Construction Preparation
[0030] Determine the pile location range: Determine the pile location range based on the design drawings.
[0031] Clean up the environment: Remove garbage and obstacles within the area of the pile location.
[0032] Place sample stakes 3: Place two sample stakes 3 within the stake location area for subsequent positioning reference.
[0033] Step 2: Installation of Guide Wall 1
[0034] Drilling: Use a down-the-hole hammer to drill the first hole Q1 in the rock strata.
[0035] Clean the installation slot: Use a rotary drilling machine to clean out the installation slot and install the installation pile 13 into the installation slot.
[0036] Positioning guide wall 1: Take the first hole Q1 as the origin of the component to create a coordinate system. Rotate the guide wall 1 according to the position of the sample pile 3 so that the X-axis of the coordinate system corresponds to one sample pile 3 and the Y-axis is parallel to two sample piles 3.
[0037] Anchoring the positioning pin: Anchor the positioning pin in the first hole Q1, and use a down-the-hole hammer to refer to the installation hole 12 to complete the construction of the remaining second holes Q2, anchor the positioning pin, and complete the fixing of the guide wall 1 to the ground.
[0038] By utilizing laser rangefinders and coordinate system construction technology, the installation position of guide wall 1 is ensured to be accurate. The hardware components on mounting holes 12 and positioning holes 14 are designed to be detachable, which facilitates dismantling after construction and improves construction flexibility.
[0039] Step 3: Positioning and Installation of Plain Pile A
[0040] Install guide rod 2: Install guide rod 2 on the positioning hole 14 and rotating hole 15 using hardware components. Guide rod 2 has a plain pile positioning hole 21 and a concrete pile positioning hole 22. Further, guide rod 2 can be made of wood or plastic. During construction, by setting an existing laser vertical positioning module on an existing rotary drilling machine, the rotary drilling machine can accurately locate the center coordinates of the plain pile positioning hole 21 to complete the operation. During operation, guide rod 2 can be rotary-cut together. After the foundation treatment is completed, a new guide rod 2 can be replaced. Preferably, the guide rod is divided into two groups, one group with a thinning treatment in the upper half and the other group with a thinning treatment in the lower half; the two groups are staggered on the guide wall body; this allows the guide rod 2 to be staggered after selection, thereby enabling the two concrete pile positioning holes 22 to coincide.
[0041] Locate the center of the plain pile Q4: Locate the center of the plain pile Q4 by referring to the coordinates of the center of the plain pile positioning hole 21.
[0042] Foundation treatment: The foundation for the placement of the foundation pile A is completed using a rotary drilling rig and a down-the-hole hammer.
[0043] Complete plain pile A: Complete the construction of plain pile A through casing and steel cage.
[0044] Step 4: Positioning and Installation of Concrete Pile B
[0045] Rotate guide rod 2: Remove the hardware components on the positioning hole 14, allowing guide rod 2 to rotate via rotating hole 15. Interlace two adjacent guide rods 2 so that the concrete pile positioning holes 22 on the guide rods 2 coincide. Then, a wooden pile can be inserted into the coincided concrete pile positioning hole 22, or the hardware components on rotating hole 15 can be tightened with nuts to fix the guide rod 2. By interlacing the guide rods 2, the center Q6 of the concrete pile appears, facilitating the positioning of the existing rotary drilling rig and achieving precise engagement between concrete pile B and plain pile A, thus improving the overall stability and bearing capacity of the pile foundation.
[0046] Locate the center Q6 of the concrete pile: Locate the center Q6 of the concrete pile by referring to the coordinates of the center of the positioning hole 22 of the concrete pile.
[0047] Foundation treatment: The foundation for placing concrete pile B is completed using a rotary drilling rig and down-the-hole hammer.
[0048] Complete concrete pile B: Concrete pile B is constructed using casing and reinforcing cage.
[0049] Step 5: Repeat construction
[0050] Repeat the steps: Repeat the positioning and installation steps of plain pile A and concrete pile B until the interlocking pile construction is completed.
