[0002] A bored pile is a type of pile made by drilling a hole in place and pouring concrete or reinforced concrete. Commonly used methods include bored piles, piles made by using spiral drills, submersible drills, etc. to drill holes in situ and pour concrete. There is no vibration and no soil squeezing during construction, but the pile settlement is slightly larger.

[0003] According to the different hole-forming methods, cast-in-place piles can be divided into bored cast-in-place piles, sunk-tube cast-in-place piles, manually excavated cast-in-place piles, explosive expansion cast-in-place piles, etc.

[0004] However, when pouring concrete for bored piles, the steel cage needs a protective layer and cannot be close to the soil in the hole. At the construction site, it is often allowed to swing or manual correction methods are used, and the quality of the pile cannot be guaranteed.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the above background technology, the prior art has the following shortcomings and defects: when pouring concrete, the bored piles are often allowed to swing or a manual deviation correction method is adopted, which cannot ensure the quality of the piles.

[0010] Furthermore, the outer surface of each limiting rod is slidably connected to the inner wall of the corresponding mounting block, and one end of each spring away from the corresponding limiting rod is fixedly connected to the inner wall of the corresponding mounting block.

[0011] Furthermore, one end of each of the limiting rods away from the corresponding fixing rod is fixedly connected to a pull rod, and the outer surface of each of the pull rods is slidably connected to the inner wall of the corresponding mounting block.

[0012] Furthermore, the inner wall of each placement block is rotatably connected to a two-way threaded rod, and the outer surface of each two-way threaded rod is threadedly connected to the inner wall of the corresponding threaded block.

[0013] Furthermore, the outer surface of the bidirectional threaded rod 1 is fixedly connected to a worm wheel, the inner wall of the fixed block is rotatably connected to a worm, and the outer surface of the worm wheel is meshed with the outer surface of the worm.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The utility model provides a fixing block, a two-way threaded rod, a connecting body and other components, inserts the limit block into the interior of the connecting body, limits the limit block through the connecting body, so that the fixing block and the connecting block are connected to the connecting body, and the fixing rod is inserted into the interior of the mounting block. After the fixing rod contacts the limit rod, the limit rod is driven to move and the spring is compressed. After that, after the fixing rod continues to move and contacts the inner wall of the mounting block, the spring is reset, and then the limit rod is pushed to the inside of the fixing rod, and the fixing rod is limited by the limit rod, so that the fixing body is connected to the threaded block. The position of the anchor bolt can be clamped by the fixing block, the connecting block and the connecting body, and the template is clamped by the four corners formed by the four fixing bodies to ensure that the anchor bolt is located in the center position and does not tilt.

[0016] 2. The utility model is provided with a fixed body, a second bidirectional threaded rod, a threaded block and other components. The rotation of the second bidirectional threaded rod drives the two threaded blocks to move on the inner wall of the placement block.

Specifically, the upper surface of each fixing body 6 is fixedly connected to a fixing rod 7, which is installed on the upper surface of the fixing body 6.

[0026] In a preferred embodiment, each limiting rod 9 is fixedly connected to a spring 10 at one end away from the corresponding fixing rod 7. By installing the spring 10 at the end of the limiting rod 9 away from the fixing rod 7, the fixing rod 7 is inserted into the interior of the mounting block 8. After the fixing rod 7 contacts the inclined surface of the limiting rod 9, the limiting rod 9 is driven to move.

The placement block 14 is installed on the bottom surface of the fixing block 1 and the connecting body 4, and the placement block 14 is fixed by the fixing block 1 and the connecting body 4.

[0027] like Figure 3 As shown, the inner wall of each placement block 14 is slidably connected to two threaded blocks 13, and the threaded blocks 13 are placed on the inner wall of the placement block 14.

The pull rod 11 is installed at the end of the limit rod 9 away from the fixed rod 7. By moving the pull rod 11, the limit rod 9 is driven to move, and the spring 10 is driven to be compressed, so that the limit rod 9 is separated from the fixed rod 7, so that the fixed rod 7 can be taken out from the inside of the mounting block 8. Thereafter, the pull rod 11 is released, and the spring 10 drives the limit rod 9 to reset.
