The reinforcement mechanism includes a fixed column, a motor, a motor shaft, a threaded rod, a fixing ring, and a plug rod. Fixed columns are attached to both sides of the bottom of the platform plate, and a motor is bolted to the middle of the top of the platform plate. The bottom of the motor is connected to a motor shaft, and the bottom of the motor shaft passes through the platform plate and is fixedly connected to a threaded rod.

[0003] The above technical solution places the motor, threaded rod, etc. in the middle of the platform plate, which will affect the pile foundation drilling and concrete grouting. In addition, the platform body is fixed to the fixed column by the first fixing bolt. The first fixing bolt is prone to breakage under shear force, which reduces the stability of the platform. Furthermore, the first fixing bolt is long, which makes it easy to install and disassemble, but it has low practicality.

[0004] Therefore, this utility model provides a pile foundation operation platform for karst geology. Utility Model Content

[0021] 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.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a pile foundation operation platform for karst geology, including a flat plate 1. Fixed columns 2 are installed at the bottom of the four corners of the flat plate 1 via an installation mechanism. The installation mechanism includes a second fixing plate 10, a square column 9, and a limiting plate 5. The square column 9 is fixedly installed at the top center of the second fixing plate 10. The limiting plate 5 is movably installed on the top of the square column 9 via a torsion spring shaft. Grooves 4 are formed inside the four corners of the top of the flat plate 1, and the limiting plate 5 is movably installed inside the grooves 4. Stabilizing mechanisms 8 are provided on both sides of the bottom of the fixed column 2. An inner groove 3 is formed at the center of the flat plate 1. The inner groove 3 facilitates pile foundation drilling and concrete grouting. The square column 9, grooves 4, and limiting plate 5 facilitate quick installation and disassembly of the flat plate 1 and the fixed column 2, making operation simple and convenient.

[0023] In this embodiment, a square groove is provided at the bottom of the groove 4, and the square column 9 is inserted and installed inside the square groove. The length of the limiting plate 5 is the horizontal diagonal length of the square column 9. The second fixing plate 10 is fixedly installed on the top of the fixing column 2. The second fixing plate 10 is set at the bottom of the plate 1 and is in close contact with the plate 1. The square groove and the square column 9 can limit each other. The limiting plate 5 can be rotated and adjusted so that the limiting plate 5 is rotated to a position that coincides with the diagonal of the square column 9, which facilitates the disassembly of the fixing column 2 and the plate 1, thereby facilitating the disassembly and transportation of the platform.

[0024] In this embodiment, the stabilizing mechanism 8 includes an inner cavity, a hydraulic rod 11, a rack 12, and a crossbar 15. The inner cavity is located inside the top of the fixed column 2, and a through hole is provided on one side of the inner cavity. The hydraulic rod 11 is fixedly installed on the top of the inner cavity. The rack 12 is slidably disposed inside the fixed column 2, and the top of the rack 12 is fixedly connected to the output rod of the hydraulic rod 11. The bottom end of the fixed column 2 has symmetrically provided mounting grooves, and the crossbar 15 is slidably disposed inside the mounting grooves. One end of the crossbar 15 has a pointed tip, and the two sides are... The mounting groove is equipped with a bidirectional screw 13 that rotates laterally. A gear 14 is fixedly installed at the middle position of the bidirectional screw 13. The gear 14 and the rack 12 are engaged in an arc shape. The crossbar 15 is screwed to the outside of the bidirectional screw 13 through a screw hole opened inside it. The hydraulic rod 11 drives the rack 12 to move downward. Through the meshing action of the rack 12 and the gear 14, the bidirectional screw 13 is rotated. The bidirectional screw 13 screws and drives the crossbars 15 on both sides to move to the outside of the fixed column 2 and insert into the interior of the karst geology, which facilitates the reinforcement of the fixed column 2.

[0025] In this embodiment, a first fixing plate 6 is slidably disposed at the top of the fixing column 2 corresponding to the lower part of the second fixing plate 10. Insert rods 7 are fixedly disposed on the four sides of the bottom of the first fixing plate 6. A screw hole is opened inside the top of the first fixing plate 6. Due to the unevenness of karst geology, the first fixing plate 6 can be raised and lowered on the fixing column 2, so that the insert rods 7 can be inserted into the ground, which facilitates secondary reinforcement of the fixing column 2 and improves the stability of the fixing column 2.

[0026] When using this pile foundation operation platform for karst geology, the platform is moved to the construction position. The limiting plate 5 is rotated on top of the square column 9. The limiting plate 5 twists the torsion spring shaft and stores force, aligning the limiting plate 5 with the diagonal of the square column 9. The fixing column 2 is then inserted into the square groove through the square column 9. The limiting plate 5 is released, and under the torque of the torsion spring shaft, it rotates in the opposite direction and stops inside the groove 4, facilitating the installation between the flat plate 1 and the fixing column 2. The fixing column 2 is then embedded into the ground, and the height of the top of the fixing column 2 is adjusted so that the limiting plate 5 is on the same horizontal plane. Taking advantage of the unevenness of the karst geology, the first fixing disc 6 slides on the fixing column 2. The first fixing plate 6 is brought into contact with the top of the karst geology, and the insertion rod 7 is inserted into the ground. A pin hole is opened on the fixing column 2 corresponding to the position of the first fixing plate 6. A pin is installed in the screw hole and pin hole at the top of the first fixing plate 6 to facilitate the fixing of the first fixing plate 6. At the same time, the hydraulic rod 11 is activated. The hydraulic rod 11 drives the rack 12 to move up and down inside the fixing column 2. The meshing action of the rack 12 and the gear 14 drives the gear 14 to rotate. The gear 14 drives the double-sided screw 13 to rotate. The double-sided screw 13 screws and drives the crossbar 15 to move to both sides and insert it into the karst geology. The drilling or grouting equipment is installed above the inner trench 3 to facilitate drilling and concrete grouting.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
