[0002] With the vigorous development of China's transportation construction industry, the construction of high-speed railways and highways has been steadily advancing. These high-standard, high-load, and high-speed engineering projects have relatively high requirements for the bearing capacity of the foundation. On the one hand, it is required that the foundation can maintain stability, and on the other hand, it is required that the post-construction settlement meets the requirements of relevant specifications. In the process of engineering construction, it is found that there are soft soil layers with high water content, large compressibility, low strength, and poor bearing capacity in some areas, that is, soft soil foundations. Under the action of the upper load, the soft soil foundation is prone to problems such as instability and excessive settlement, which seriously affect the project quality and delay the construction period.

[0003] The existing compaction pile devices generally first drill pile holes. During the process of drilling pile holes on the surface of the soft foundation, the compaction pile device is prone to getting stuck on the ground, and it takes a lot of time to get out of trouble after the later construction is completed, which is very troublesome.

[0020] The present invention provides a collapsible loess-lime soil compaction pile device and a method of using the same, which has the following improvements and advantages over the prior art:

[0021] First, the present invention moves the vehicle body on the ground to a suitable piling position, and then the hydraulic cylinder works to drive the mobile frame to move on two slide rails. The mobile frame drives the pile body limiting assembly to move above the piling position, and then the two supporting mechanisms work to insert the bottom end of the pile into the soft foundation. The two supporting mechanisms support the vehicle body to ensure that the vehicle body will not sink into the ground during the piling process, avoiding the need to spend a lot of time to escape after the construction is completed, and ensuring the convenience of construction.

[0022] Secondly, the present invention drives the cross fixing frame and the support ring to move downward through the hydraulic push rod, and the support ring drives a number of ground cones to be inserted into the soft foundation for support, ensuring that the vehicle body will not sink into the ground during the piling process, avoiding the need to spend a lot of time to escape danger after the later construction is completed.

[0023] Third: The present invention drives the control gear to rotate by controlling the operation of the motor. The control gear uses the displacement racks in the two connectors to drive the connecting posts in the two connectors to move away from each other. The connecting posts in the two connectors move away from each other until they are separated from the corresponding hexagonal slots, thereby realizing the downward movement of the lifting block.

On the top of the vehicle body 1, two slide rails 3 are symmetrically arranged. A moving frame 4 is slidably mounted on the two slide rails 3. A hydraulic cylinder 5 is horizontally arranged on the top of the vehicle body 1. The output end of the hydraulic cylinder 5 is connected to the rear outer wall of the moving frame 4. Two vertical rails 6 are symmetrically arranged on the front outer wall of the moving frame 4. A lifting block 7 is slidably mounted on the two vertical rails 6. A pile body limiting component 8 is arranged on the outer wall of the lifting block 7. A lifting component 9 is arranged on the top of the moving frame 4. The bottom end of the lifting component 9 is connected to the lifting block 7. The vehicle body 1 moves on the ground to a suitable piling position. Then the hydraulic cylinder 5 works to drive the moving frame 4 to move on the two slide rails 3. The moving frame 4 drives the pile body limiting component 8 to move above the piling position. Then the two support mechanisms 2 work to insert their bottom ends into the soft ground. The two support mechanisms 2 support the vehicle body 1 to ensure that the vehicle body 1 will not sink into the ground during the piling process, avoiding spending a lot of time to get out of trouble after the later construction is completed and ensuring the convenience of construction. Then the lifting component 9 works to move the lifting block 7 downward on the two vertical rails 6. The lifting block 7 drives the pile body in the pile body limiting component 8 to move downward to the ground surface. Finally, the lifting component 9 continues to work to slowly move the pile body downward into the ground surface to complete the entire piling operation.

By operating the control component 92 to drive the separation of its two sides from the corresponding hexagonal slots, then under the action of gravity, the lifting block 7 moves downward on the two vertical rails 6. The lifting block 7 drives the pile body in the pile body limiting component 8 to move downward to the ground surface. Then the hydraulic cylinder 93 operates to drive the pile driving plate 94 to move downward. The pile driving plate 94 moves downward to strike the pile driving frame 82 downward.
