The dynamic compaction assembly comprises a dynamic compaction part and a reinforcing part. The dynamic compaction part is located at the top of the moving frame, and a drainage part is arranged outside the dynamic compaction part. With the downward movement of a tamping plate, a lower pressing plate is driven to move downward, and then a L-shaped plate II is driven to move downward, so that the L-shaped plate II drives a fixed plug to move downward and is inserted into the soft soil foundation, thereby ensuring the stability of the whole device when the soft soil foundation is tamped. After the tamping plate moves to the uppermost position, a spring lifts a connecting plate, thereby driving the L-shaped plate II to move upward, the fixed plug can be pulled out of the soft soil foundation, and the whole device can be normally moved.

Description

Technical Field

[0001] This invention relates to the field of soft soil foundation treatment technology, specifically to a dynamic compaction device based on the static dynamic drainage consolidation method. Background Technology

[0002] Dynamic compaction is an easy-to-operate and economical technique for reinforcing soft soil foundations. This method involves a hammer falling freely from a certain height, using the resulting shock waves and stress to reinforce the foundation. Initially, this method was primarily used for reinforcing sandy and coarse-grained soil foundations. However, soft clay foundations have undesirable characteristics such as high porosity, low permeability, and high compressibility, and are typically highly saturated, making dynamic compaction unsuitable. When using dynamic drainage consolidation to reinforce saturated soft clay foundations, vertical drainage channels need to be pre-installed in the soil. The impact force generated by dynamic compaction creates excess pore water pressure in the soil, causing the pore water to drain along the drainage channels, thus promoting soil consolidation. While existing dynamic compaction devices can generate excess pore water pressure through the impact force, causing pore water to drain along the channels, after a period of time, the remaining drainage cannot flow directly out of the channels and naturally flows back to the bottom, failing to improve the reinforcement efficiency of soft soil foundations. Summary of the Invention

An air pump is fixedly installed at the top of the gas-liquid separator, and the air inlet end of the air pump extends into the gas-liquid separator.

[0007] Preferably, the reinforcing part includes an L-shaped plate and a lower pressure plate. The L-shaped plate is fixedly installed at the bottom of the movable frame. A limit rod is fixedly installed on the outer wall of the bottom end of the L-shaped plate. The top end of the limit rod is fixedly connected to the bottom of the movable frame. A spring is movably sleeved on the outer wall of the limit rod. A connecting plate is fixedly installed on the top end of the spring.

[0008] Preferably, the processing unit includes a permeable plate, a filter plate, a separation plate, and a water storage tank. The permeable plate, filter plate, and separation plate are fixedly installed on the inner wall of the gas-liquid separator. The water storage tank is fixedly installed on the top of the movable frame. The water storage tank is connected to the interior of the gas-liquid separator through a water pipe. A water level plate is provided inside the water storage tank. A drain pipe is connected to the outer side wall of the water storage tank.

[0009] Preferably, there are two drainage sections, which are symmetrically distributed about the left and right sides of the movable frame, and the drainage sections correspond to the well point pipes located on the left and right sides of the movable frame.

[0010] Preferably, the outer diameter of the pumping pipe is smaller than the inner diameter of the well point pipe, a closed door is fixedly installed on the front of the gas-liquid separator, and the disassembly joint is fixedly connected to the pumping pipe through a flange.

[0011] Preferably, the filter plate is located above the connection between the hose and the gas-liquid separator, and the separator plate is located below the connection between the hose and the gas-liquid separator.

[0012] Preferably, the water level plate is a hollow plastic plate, and the connection between the water pipe and the water storage tank is located at the bottom of the inside of the water storage tank.

[0013] This invention provides a dynamic compaction device based on the static dynamic drainage consolidation method. This dynamic compaction device based on the static dynamic drainage consolidation method has the following beneficial effects: This dynamic compaction device, based on the static dynamic drainage consolidation method, moves the compaction plate downwards, causing the rack to move downwards, which in turn rotates the gear, which in turn rotates the second shaft. The rotation of the second shaft, through the pulley set, drives the first shaft to rotate, which in turn drives the winding wheel to rotate and retract the wire rope. This lifts the disassembly joint and the water pumping pipe upwards, allowing the water squeezed into the well point pipe under the force of the soft soil foundation to rise normally. At the same time, the air pump is turned on to extract the air from the gas-liquid separator tank, and then the air squeezed out by the water flow is drawn into the gas-liquid separator tank through the water pumping pipe, accelerating the air flow rate, thereby reducing the resistance when the water flow rises, increasing the height of the water jet, and allowing more water to be sprayed out from the well point pipe. After the compaction plate moves upwards, it drives the rack to move upwards, causing the gear to reverse. At this time, the water pumping pipe moves downwards and extends into the well point pipe to extract the water remaining in the well point pipe, ensuring the water discharge rate in the well point pipe. This dynamic compaction device based on the static dynamic drainage consolidation method moves the compaction plate downward, causing the lower pressure plate to move downward. The lower pressure plate moves downward and contacts the supporting plate, which in turn moves the L-shaped plate downward. This allows the L-shaped plate to move the fixed insertion rod downward and insert it into the soft soil foundation, ensuring the stability of the entire device when compacting the soft soil foundation. After the compaction plate moves to the top, the spring lifts the connecting plate, which in turn moves the L-shaped plate upward, allowing the fixed insertion rod to be pulled out from the soft soil foundation and the entire device to move normally. The dynamic compaction device based on the static dynamic drainage consolidation method introduces mud, water, and air into the gas-liquid separation tank. The air passes through the filter plate and the air permeable plate before entering the air pump and being discharged. The water in the mud is separated by the separation plate and enters the water storage tank, increasing the weight of the entire device and thus improving its overall stability. As the water in the storage tank increases, it lifts the water level plate until it moves above the drain pipe, at which point the water flows out from the drain pipe, preventing the storage tank from becoming too full and causing movement difficulties.

Detailed Implementation Example 1

[0016] A preferred embodiment of the dynamic compaction device based on the static-dynamic drainage consolidation method provided by the present invention is as follows: Figures 1 to 5 As shown: A dynamic compaction device based on the static dynamic drainage consolidation method includes a mobile frame 1 and a soft soil foundation 5; Well point pipe 4 inserted into the soft soil foundation 5; The casters 2 are fixedly installed at the bottom of the mobile frame 1; The dynamic compaction assembly 3 is installed on the mobile frame 1. The dynamic compaction assembly 3 includes a dynamic compaction part 31 and a reinforcing part 33. The dynamic compaction part 31 is located at the top of the mobile frame 1. A drainage part 32 is provided on the outside of the dynamic compaction part 31. A treatment part 34 is provided inside the drainage part 32. The reinforcing part 33 is located at the bottom of the mobile frame 1. The dynamic compaction section 31 includes a fixed frame 311, which is fixedly installed on the top of the movable frame 1. A lifting device 312 is fixedly installed on the outer wall of the fixed frame 311, and a compaction plate 313 is fixedly installed on the extended end of the lifting device 312. The drainage section 32 includes a fixed plate 323, which is fixedly installed on the outer wall of the movable frame 1. A second rotating shaft 3213 is rotatably connected to the inner wall of the fixed plate 323 via a bearing. A gear 321 is fixedly installed on the outer wall of the second rotating shaft 3213, and the gear 321 meshes with a rack 322. The bottom end of the rack 322 is fixedly connected to the top end of the compaction plate 313. The second rotating shaft 3213 is driven by a first rotating shaft 329 via a pulley set 324. The left and right ends of the first rotating shaft 329 are rotatably connected to the outer wall of the fixed plate 323 via bearings. A winding wheel 328 is fixedly installed on the outer wall of the first rotating shaft 329, and a steel wire rope 3 is wound around the outer wall of the winding wheel 328. 27. A disassembly and assembly connector 326 is fixedly installed at the bottom end of the wire rope 327. A water pumping pipe 325 is connected to the bottom end of the disassembly and assembly connector 326. A hose 3210 is connected to the water inlet end of the disassembly and assembly connector 326. A gas-liquid separator 3212 is connected to the end of the hose 3210 away from the disassembly and assembly connector 326. An air pump 3211 is fixedly installed at the top of the gas-liquid separator 3212. The air inlet end of the air pump 3211 extends into the gas-liquid separator 3212. There are two drainage parts 32, which are symmetrically distributed on the left and right sides of the moving frame 1. The drainage parts 32 correspond to the well point pipes 4 located on the left and right sides of the moving frame 1. The outer diameter of the water pumping pipe 325 is smaller than the inner diameter of the well point pipe 4. The air pump 3211 is used to extract the air in the gas-liquid separator 3212. The negative pressure causes the water pumping pipe 325, which extends into the well point pipe 4, to extract the water in the well point pipe 4, thereby accelerating the discharge of water in the well point pipe 4.

[0017] Furthermore, a closed door is fixedly installed on the front of the gas-liquid separator 3212. The mud inside the gas-liquid separator 3212 can be removed after the closed door is opened.

Example 2

[0018] Based on Example 1, the preferred embodiment of the present invention provided by the present invention is as follows: Figures 1 to 5As shown: The reinforcing part 33 includes an L-shaped plate 331 and a lower pressure plate 334. The L-shaped plate 331 is fixedly installed at the bottom of the movable frame 1. A limit rod 332 is fixedly installed on the outer wall of the bottom end of the L-shaped plate 331. The top end of the limit rod 332 is fixedly connected to the bottom of the movable frame 1. A spring 333 is movably sleeved on the outer wall of the limit rod 332. A connecting plate 338 is fixedly installed on the top end of the spring 333. The limit rod 332 movably passes through the bottom of the connecting plate 338.

The upper surface of the receiving plate 335 is in contact with the lower surface of the lower pressure plate 334. The fixing pin 337 is inserted into the soft soil foundation 5 by the downward movement of the L-shaped plate 336, which increases the stability of the device. A spring 333 is set to push the connecting plate 338 upward, which in turn drives the L-shaped plate 336 upward, so that the fixing pin 337 is detached from the soft soil foundation 5. Example 3

[0019] Based on Example 1, the preferred embodiment of the present invention provided by the present invention is as follows: Figures 1 to 5 As shown: The processing unit 34 includes a venting plate 341, a filter plate 342, a separation plate 343, and a water storage tank 347. The venting plate 341, filter plate 342, and separation plate 343 are fixedly installed on the inner wall of the gas-liquid separator 3212. The water storage tank 347 is fixedly installed on the top of the movable frame 1. The water storage tank 347 is connected to the interior of the gas-liquid separator 3212 through a water pipe 344. A water level plate 345 is provided inside the water storage tank 347. A drain pipe 346 is connected to the outer side wall of the water storage tank 347. The filter plate 342 is located above the connection between the hose 3210 and the gas-liquid separator 3212. The separation plate 343... 43 is located below the connection between the hose 3210 and the gas-liquid separator 3212. The water level plate 345 is a hollow plastic plate. The connection between the water pipe 344 and the water storage tank 347 is located at the bottom inside the water storage tank 347. A filter plate 342 is installed to block the mud and water below the filter plate 342. A vent plate 341 is installed to filter the air entering above the filter plate 342, blocking the water vapor and preventing it from entering the air pump 3211. A separation plate 343 is installed to separate the mud and water, so that the water passes through the separation plate 343 and enters the water storage tank 347 through the water pipe 344 below the separation plate 343.

[0020] In use, the invention activates the lifting device 312, causing the compaction plate 313 to move downwards and compact the soft soil foundation 5. As the compaction plate 313 moves downwards, it causes the rack 322 to move downwards, resulting in the rotation of the gear 321. This rotation, in turn, causes the second rotating shaft 3213 to rotate. The rotation of the second rotating shaft 3213, through the pulley group 324, drives the first rotating shaft 329 to rotate, which in turn drives the winding wheel 328 to rotate, retracting the wire rope 327. This lifts the disassembly joint 326 and the pumping pipe 325 upwards, allowing the water squeezed into the well point pipe 4 from the soft soil foundation 5 to rise normally. When the air pump 3211 is turned on, the air in the gas-liquid separator 3212 is extracted. Then, the air squeezed out by the water flow is drawn into the gas-liquid separator 3212 through the water pump pipe 325, accelerating the air flow rate, thereby reducing the resistance when the water flows upward and increasing the height of the water jet, so that more water can be sprayed out from the well point pipe 4. After the compaction plate 313 moves upward, it drives the rack 322 to move upward, causing the gear 321 to reverse. At this time, the water pump pipe 325 moves downward and extends into the well point pipe 4, removing the water remaining in the well point pipe 4 and ensuring that the water in the well point pipe 4 is clean. The water discharge rate is adjusted as the compaction plate 313 moves downward, causing the lower pressure plate 334 to move downward. The lower pressure plate 334 then moves downward against the receiving plate 335, which in turn moves the L-shaped plate 336 downward. This causes the L-shaped plate 336 to move the fixing pin 337 downward and insert it into the soft soil foundation 5, ensuring the stability of the entire device during the compaction of the soft soil foundation 5. After the compaction plate 313 moves to the top, the spring 333 lifts the connecting plate 338, which in turn causes the L-shaped plate 336 to rise, allowing the fixing pin 337 to be pulled out of the soft soil foundation 5 and enabling the entire device to move normally. The device receives mud, water, and air from the gas-liquid separator 3212. The air passes through the filter plate 342 and the vent plate 341 before entering the air pump 3211 and being discharged. The water in the mud is separated by the separator plate 343 and enters the water storage tank 347, increasing the weight of the entire device and thus improving its stability. As the water in the water storage tank 347 increases, it lifts the water level plate 345 until it moves above the drain pipe 346, at which point the water flows out from the drain pipe 346, preventing the water in the water storage tank 347 from becoming too full and causing difficulty in movement.
