Description

Technical Field

[0001] This utility model relates to the field of positioning structure technology, and in particular to a positioning structure for cement-soil mixing piles. Background Technology

[0002] In the construction of cement-soil mixing piles, the positioning accuracy of the piles directly affects the overall effect of the foundation treatment. Excessive positioning deviation not only leads to uneven pile distribution, affecting the stress balance of the composite foundation, but also may result in insufficient overlap or excessive overlap between adjacent piles, reducing the foundation's impermeability and structural stability, and even causing potential engineering quality problems. Currently, the positioning structures used in cement-soil mixing pile construction mostly employ anchor rods inserted into the bottom surface for fixation. Due to the complex soil properties at the construction site, if the soil is relatively loose, the anchor rods may not provide sufficient anchoring force after insertion. Under the influence of vibrations generated by the mixing device and external wind forces, they are prone to shaking, and may even loosen after prolonged use. This not only causes the positioning structure itself to shift, resulting in inaccurate pile positioning, but also may affect the safety of the entire construction process due to shaking and loosening, increasing the probability of rework and seriously impacting construction progress and quality. Therefore, this utility model proposes a positioning structure for cement-soil mixing piles. Utility Model Content

[0003] The purpose of this invention is to address the problem that existing positioning structures in the background technology often use anchor rods inserted into the bottom surface for fixation. Due to the complex soil properties of the construction site, if the soil is relatively loose, the anchor rods are difficult to provide sufficient anchoring force after insertion. Under the influence of vibrations generated by the operation of the mixing device and external wind forces, they are prone to shaking. After prolonged use, they may even loosen. This not only causes the positioning structure itself to shift, resulting in inaccurate pile construction positions, but also may affect the safety of the entire construction process due to shaking and loosening, increasing the probability of rework and seriously affecting the construction progress and quality. Therefore, this invention proposes a cement-soil mixing pile positioning structure.

[0004] The technical solution of this utility model: A positioning structure for cement-soil mixing piles includes: a fixing frame, the upper surface of which has a first through groove, and a fixing component for positioning the mixing device is provided on the upper surface of the fixing frame; a support plate fixedly disposed on both sides of the fixing frame, and a positioning limiting component is provided on both sides of the fixing frame, the limiting component being located directly above the support plate; a connecting plate fixedly disposed between the fixing frames, the upper surface of which has a second through groove, and a stabilizing component for positioning the fixing frame is provided on the second through groove.

[0006] Optionally, the limiting assembly comprises fixing plates fixedly arranged on both sides of the fixing frame, a second threaded bolt is arranged on the fixing plate in a threaded penetrating manner, a moving plate is rotatably arranged at the lower end of the second threaded bolt, and a plurality of insertion rods are fixedly arranged on the bottom surface of the moving plate.

[0007] Optionally, the stabilizing assembly comprises a frame fixedly arranged on one side of the fixing frame, a third threaded rod is arranged on the frame in a threaded penetrating manner, one end of the third threaded rod is rotatably connected with a connecting block, two ends of the connecting block are respectively and rotatably connected with a linkage plate, one end of the linkage plate is rotatably provided with a connecting seat, one end of the connecting seat is fixedly connected with a limiting plate, and the outer annular surface of the limiting plate is fixedly provided with an insertion block.

[0009] Optionally, the fixing frame and the frame are arranged in a "Jiong"-shaped structure.

[0010] Optionally, the limiting plate is arranged in an arc-shaped structure.

[0011] In summary, the present application includes at least the following beneficial technical effects:

[0012] In the present utility model, when the third threaded rod on the frame in the stabilizing assembly rotates, it will push the connecting block to move, and the connecting block drives the linkage plate to rotate, so that the connecting seat pushes the arc-shaped limiting plate to approach the inner wall of the mixing pile hole, and finally the insertion block on the outer annular surface of the limiting plate is inserted into the inner wall of the pile hole, forming precise limiting of the pile hole position. Combined with the rotation of the second threaded bolt on the fixing plate of the limiting assembly to drive the moving plate to move down, the multiple insertion rods on the bottom surface of the moving plate are inserted into the bottom soil. Even in soft soil, the multiple insertion rods can disperse the force and provide sufficient anchoring force. The combination of the two fixes the positioning structure from the two dimensions of the inner wall of the pile hole and the ground, effectively resisting the vibration of the mixing device during operation and the influence of external wind force, avoiding the shaking or loosening of the positioning structure, and ensuring the accurate construction position of the pile body;

[0033] Further, two sides of the fixing frame 1 are provided with limiting assemblies 5 for positioning. The limiting assembly 5 includes fixing plates 51 fixedly arranged on both sides of the fixing frame 1. A second threaded bolt 52 is arranged through the fixing plate 51 in a threaded fit manner. The lower end of the second threaded bolt 52 is rotatably provided with a moving plate 53 through a bearing. A plurality of inserting rods 54 are fixedly arranged on the bottom surface of the moving plate 53, and the inserting rods 54 are movably sleeved with the guide through holes 9. Rotating the second threaded bolt 52 can drive the plurality of inserting rods 54 at the bottom of the moving plate 53 to move vertically up and down simultaneously.

[0034] As shown in Figure 1 and Figure 3 , the second through groove 7 is provided with a stabilizing assembly 8 for positioning the fixing frame 1. The stabilizing assembly 8 includes a frame 81 fixedly arranged on one side of the fixing frame 1, and the frame 81 is configured in a "⊃⊂" shape.
