UTILITY MODEL CONTENT

[0004] In order to make up for the above shortcomings, the utility model provides a kind of excavation section solidification equipment in situ suitable for weak foundation soil, aims at improving the problems in prior art that using pile foundation reinforcement from early geological survey to pile foundation construction, each step needs rigorous promotion, under the influence of geological condition and pile type, speed is limited, affect project progress.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an in-situ stabilization device suitable for excavated sections of soft foundation soil, comprising a tracked vehicle, a bulldozer blade rotatably connected to the left side of the tracked vehicle, a hydraulic rod rotatably connected to the top left side of the tracked vehicle, the left end of the hydraulic rod rotatably connected to the bulldozer blade, a fixed frame fixedly connected to the top of the tracked vehicle, a main shaft rotatably connected to the top center of the fixed frame, a universal joint fixedly connected to the left end of the main shaft, a secondary shaft fixedly connected to the bottom end of the universal joint, the secondary shaft rotatably connected to the left side of the outer wall of the fixed frame, and the universal joint rotating with the fixed frame. The system is dynamically connected, with a connecting rod slidably connected to the inner wall of the secondary shaft. A planetary gear set is fixedly connected to the bottom of the connecting rod, and multiple stirring rods are fixedly connected to the bottom of the planetary gear set. A motor is fixedly connected to the top right side of the fixed frame, and the output end of the motor is fixedly connected to the main shaft. A storage tank is fixedly connected to the top right side of the tracked vehicle. A metering pump is connected to the bottom left side of the storage tank, and a conveying pipe is connected to the top of the metering pump. An annular nozzle is connected to the left end of the conveying pipe, and the annular nozzle is fixedly connected to the outer wall of the planetary gear set. A height adjustment mechanism is provided on the left side of the outer wall of the fixed frame.

[0006] The above technical solution utilizes a tracked vehicle as the mobile carrier for the entire system, enabling it to move through excavation sections in soft soil. A bulldozer blade is rotatably connected to its left side, and a hydraulic rod is rotatably connected to its top left side. The hydraulic rod connects the tracked vehicle and the bulldozer blade at both ends, allowing for extension and retraction to change the angle and position of the bulldozer blade, thus clearing the soil and laying the foundation for subsequent stabilization work. A mounting frame on top of the tracked vehicle provides support and connection. The motor is fixed to the top right side of the mounting frame; upon startup, its output drives the main shaft to rotate. The main shaft is connected to the secondary shaft via a universal joint, which allows for adjustments in the angular misalignment between the main and secondary shafts. Power is transmitted in real time. The secondary shaft is rotatably connected to the left side of the outer wall of the fixed frame, and the inner wall is slidably connected to the connecting rod. When the motor runs, the power is transmitted sequentially through the main shaft and universal joint to the secondary shaft, which drives the connecting rod to rotate. This, in turn, causes the planetary gear set at the bottom of the connecting rod to rotate, driving multiple mixing rods to mix the foundation soil. The storage tank fixed on the right side of the top of the tracked vehicle is used to store the solidification material. The metering pump connected to the bottom left side of the storage tank precisely controls the material delivery volume. The material is sent to the annular nozzle fixed on the outer wall of the planetary gear set through the delivery pipe. When the mixing rods are mixing, the annular nozzle sprays the material simultaneously to achieve on-site solidification.

[0007] As a further description of the above technical solution:

[0008] The height adjustment mechanism includes a sliding plate, which is slidably connected to the left side of the outer wall of the fixed frame. The left side of the sliding plate is fixedly connected to the annular nozzle. A groove is provided on the left side of the outer wall of the fixed frame, and the sliding plate is slidably connected to the groove. A telescopic rod is fixedly connected to the left side of the outer wall. A connecting plate is fixedly connected to the top of the sliding plate, and the bottom end of the telescopic rod is fixedly connected to the connecting plate.

[0009] Through the above technical solution: when the equipment needs to adjust the height of components connected to the sliding plate, such as the mixing rod and the annular nozzle, the telescopic rod becomes the key actuator. If the goal is to raise these components, the telescopic rod will shorten, generating tension that acts on the connecting plate, thereby pulling the connected sliding plate. Due to the sliding relationship between the sliding plate and the chute, the sliding plate will slide upward along the chute, thus raising the height of components such as the mixing rod and the annular nozzle. Conversely, if the height of the relevant components needs to be lowered, the telescopic rod will extend, generating thrust that pushes the connecting plate, causing the sliding plate to slide downward along the chute, thus successfully lowering the height of components such as the mixing rod and the annular nozzle. This meets the different height requirements of equipment components for treating soft soil foundations at different depths.

[0010] As a further description of the above technical solution:

[0011] The storage tank has a filling port at the top center, and the inner wall of the filling port is threaded with a plug.

[0012] The above technical solution involves a filling port located at the top center of the storage tank for injecting solidifying material. The cap is threaded to the inner wall of the filling port to prevent material leakage and the entry of debris.

[0013] As a further description of the above technical solution:

[0014] An installation box is fixedly connected to the top front side of the storage tank, and an alarm light is fixedly connected to the inner wall of the installation box.

[0015] The above technical solution involves installing an alarm light in the box, which is linked to the storage tank. When the storage tank experiences conditions such as insufficient material or abnormal pressure, the alarm light will illuminate to issue a warning.

[0016] As a further description of the above technical solution:

[0017] An information sign is provided on the front middle part of the outer wall of the storage tank. Screws are threaded to the four corners of the outer wall of the information sign, and the rear ends of the screws are threaded to the storage tank.

[0018] The above technical solution allows the information board to be securely fixed to the front of the outer wall of the storage tank using screws at its four corners. It is used to record various relevant information. If it needs to be replaced or updated, simply unscrew the screws. The operation is convenient.

[0019] As a further description of the above technical solution:

[0020] A controller is fixedly connected to the right end of the front side of the outer wall of the storage tank. The controller is electrically connected to the hydraulic rod, the motor and the metering pump.

[0021] The above technical solution involves a controller installed on the outer wall of the storage tank, which, through electrical connection, comprehensively regulates the hydraulic rod, motor, and metering pump. This plays a crucial role in ensuring that all components work in close coordination.

[0022] As a further description of the above technical solution:

[0023] The top of the bulldozer blade is fixedly connected to a mounting base, and multiple lights are fixedly connected to the front and rear sides of the left end of the outer wall of the mounting base.

[0024] The above technical solution enables the lighting to be turned on when there is insufficient light, illuminating the work area and facilitating efficient bulldozing operations.

[0025] As a further description of the above technical solution:

The storage tank, metering pump, delivery pipe and annular spray pipe work together to evenly spray the solidification material. There is no need for complicated pile foundation reinforcement process, and it is not limited by geological conditions and pile type. It greatly improves the construction speed, speeds up the project progress and effectively improves the problem of limited construction progress in the existing technology.

[0030] 2. In this utility model, the sliding connection between the sliding plate and the chute, combined with the connection structure between the telescopic rod and the connecting plate, enables flexible adjustment of the height of the mixing rod and the annular nozzle. By extending and retracting the telescopic rod, the rise or fall of related components can be precisely controlled, effectively improving the problem that traditional treatment methods are difficult to adapt to soft foundation soils of different depths. Without the need for complex measurements and reassembly, the working height can be quickly adjusted according to the actual situation, improving the adaptability and efficiency of on-site solidification operations.

[0039] Reference Figure 1 , Figure 3 and Figure 5 This utility model provides an embodiment of an in-situ stabilization device suitable for excavated sections of soft foundation soil. The device includes a tracked vehicle 1, which serves as the mobile carrier for the entire equipment, providing mobility for operation in excavated sections of soft foundation soil. A bulldozer blade 3 is rotatably connected to the left side of the tracked vehicle 1 for clearing the surface soil of the excavated section.

A universal joint 7 is fixedly connected to the left end of the main shaft 6, ensuring smooth power transmission even when there is an angular misalignment between the main shaft 6 and the secondary shaft 8. A secondary shaft 8 is fixedly connected to the bottom end of the universal joint 7, further transmitting power to the connecting rod 9. The secondary shaft 8 is rotatably connected to the left side of the outer wall of the mounting bracket 5, ensuring stable rotation and power transmission. The universal joint 7 rotatably connects to the mounting bracket 5, further enhancing the flexibility of power transmission. The connecting rod 9 is slidably connected to the inner wall of the secondary shaft 8, allowing for adjustments based on actual needs. The height of the mixing rod 1 is adjusted by sliding along the inner wall of the secondary shaft 8. A planetary gear set 10 is fixedly connected to the bottom of the connecting rod 9, distributing power evenly to multiple mixing rods 11. Multiple mixing rods 11 are fixedly connected to the bottom of the planetary gear set 10 to mix the soft foundation soil. A motor 12 is fixedly connected to the top right side of the fixed frame 5, providing power for the entire mixing and curing process. The output end of the motor 12 is fixedly connected to the main shaft 6, ensuring that the power of the motor 12 can be effectively transmitted to the main shaft 6. A storage tank 13 is fixedly connected to the top right side of the tracked vehicle 1 for storing the materials required for curing. The bottom of the storage tank 13... A metering pump 14 is connected to the left side to precisely control the amount of solidifying material delivered. The top of the metering pump 14 is connected to a delivery pipe 15, which delivers the solidifying material drawn by the metering pump 14 to the annular nozzle 16. The left end of the delivery pipe 15 is connected to the annular nozzle 16, which sprays the solidifying material evenly into the foundation soil during mixing. The annular nozzle 16 is fixedly connected to the outer wall of the planetary gear set 10 to ensure that the solidifying material is sprayed synchronously and evenly during mixing. A height adjustment mechanism 2 is provided on the left side of the outer wall of the fixed frame 5. The height adjustment mechanism 2 can flexibly adjust the working height of the mixing rod 11 and the annular nozzle 16 according to the actual situation of the soft foundation soil.

[0040] Specifically, the tracked vehicle 1 serves as the mobile carrier of the entire equipment, providing mobility for excavation work on soft foundation soil. Its left-side rotating bulldozer blade 3 cooperates with the top left-side rotating hydraulic rod 4. One end of the hydraulic rod 4 is connected to the tracked vehicle 1, and the other end to the bulldozer blade 3. By extending and retracting the hydraulic rod 4, the angle and position of the bulldozer blade 3 can be flexibly changed to clear the soil and prepare the site for subsequent stabilization work. The fixed frame 5 provides support and connection. The motor 12 is fixed to the top right side of the fixed frame 5, and its output end drives the main shaft 6 connected to it to rotate. The main shaft 6 is connected to the secondary shaft 8 through a universal joint 7. The universal joint 7 can transmit power when there is an angular deviation between the main shaft 6 and the secondary shaft 8. The secondary shaft 8 is connected to the fixed frame 5 externally. The left side of the wall is rotatably connected, and the inner wall is slidably connected to the connecting rod 9. When the motor 12 starts, the power is transmitted to the auxiliary shaft 8 through the main shaft 6 and universal joint 7, which drives the connecting rod 9 to rotate. The planetary gear set 10 at the bottom of the connecting rod 9 rotates accordingly, thereby driving multiple mixing rods 11 to mix the foundation soil, realizing the turning and mixing of the soft foundation soil. The storage tank 13 is fixed on the top right side of the tracked vehicle 1 to store the solidification material. The metering pump 14 connected to the bottom left side precisely controls the material delivery amount. The material is sent to the annular nozzle 16 through the delivery pipe 15. The annular nozzle 16 is fixed on the outer wall of the planetary gear set 10. When the mixing rod 11 is mixing, the annular nozzle 16 sprays the solidification material simultaneously, so that the two are fully mixed and the in-situ solidification is completed.

[0041] Reference Figure 1 , Figure 3 and Figure 5 The height adjustment mechanism 2 includes a slide plate 201, which is slidably connected to the left side of the outer wall of the fixed frame 5. The left side of the slide plate 201 is fixedly connected to the annular nozzle 16, which is used to support and drive the connected components to achieve height changes. A groove 202 is provided on the left side of the outer wall of the fixed frame 5, which provides a limited sliding track for the slide plate 201, ensuring that the slide plate 201 can only move up and down in a specific direction. The slide plate 201 is slidably connected to the groove 202. A telescopic rod 203 is fixedly connected to the left side of the outer wall of the fixed frame 5, which is the power component that drives the slide plate 201 to move up and down. The height position of the slide plate 201 is changed by its own extension and retraction. A connecting plate 204 is fixedly connected to the top of the slide plate 201. The bottom end of the telescopic rod 203 is fixedly connected to the connecting plate 204, which serves to connect the slide plate 201 and the telescopic rod 203, so that the power of the telescopic rod 203 can be effectively transmitted to the slide plate 201.

[0042] Specifically, the slide plate 201 is slidably connected to the slide groove 202 on the left side of the outer wall of the fixed frame 5, providing a track for the slide plate 201 to move up and down. The telescopic rod 203 fixed on the left side of the outer wall of the fixed frame 5 has its bottom end fixedly connected to the connecting plate 204 on the top of the slide plate 201. When the height needs to be adjusted, the telescopic rod 203 plays a key role. If the height of the parts connected to the slide plate 201 is to be raised, the telescopic rod 203 is shortened, pulling the connecting plate 204, which in turn drives the slide plate 201 to slide upward along the slide groove 202, thereby raising the stirring rod 11, the annular nozzle 16 and other parts connected to the slide plate 201. Conversely, when the telescopic rod 203 is extended, it pushes the connecting plate 204, causing the slide plate 201 to slide downward along the slide groove 202, reducing the height of the relevant parts.

[0043] Reference Figure 1 , Figure 2 and Figure 4 The storage tank 13 has a filling port 17 at the top center for injecting curing material. A plug 18 is threaded to the inner wall of the filling port 17 to prevent material leakage and the entry of debris. A mounting box 19 is fixedly connected to the front side of the top of the storage tank 13. An alarm light 20 is fixedly connected to the inner wall of the mounting box 19. The alarm light 20 illuminates when the storage tank 13 malfunctions. An information plate 21 is set on the front center of the outer wall of the storage tank 13 for recording relevant information. Screws 22 are threaded to the four corners of the outer wall of the information plate 21. The rear ends of the screws 22 are threaded to the storage tank 13.

[0044] Specifically, the filling port 17 at the top center of the storage tank 13 is used to inject solidified material. The plug 18 is connected to the inner wall of the filling port 17 by threads to prevent material leakage and the entry of foreign matter. The alarm light 20 in the mounting box 19 illuminates to warn of any abnormal situation in the storage tank 13. The information plate 21 is fixed to the front side of the outer wall of the storage tank 13 by screws 22 at the four corners and is used to record relevant information. Unscrewing the screws 22 makes it easy to replace or update the information.

[0045] Reference Figure 1 , Figure 2 and Figure 5 A controller 23 is fixedly connected to the right front end of the outer wall of the storage tank 13. The controller 23 is electrically connected to the hydraulic rod 4, the motor 12 and the metering pump 14 respectively, and uniformly controls the hydraulic rod 4, the motor 12 and the metering pump 14 to ensure that all components work together. A mounting base 24 is fixedly connected to the top of the bulldozer blade 3. Multiple lights 25 are fixedly connected to the front and rear sides of the left side of the outer wall of the mounting base 24 to illuminate the working area when the light is poor, which facilitates bulldozing operations. Multiple pipe rings 26 are fixedly connected to the top front side of the fixed frame 5. The inner walls of the multiple pipe rings 26 are slidably connected to the conveying pipe 15 to stabilize the conveying pipe 15, prevent it from shaking, and ensure stable delivery of the solidified material.

[0046] Specifically, the controller 23 on the outer wall of the storage tank 13 is electrically connected to uniformly control the hydraulic rod 4, motor 12 and metering pump 14 to ensure that all components work together. The lighting 25 on the top mounting base 24 of the bulldozer blade 3 illuminates the work area when the light is poor, which facilitates bulldozing operations. The pipe ring 26 on the top of the fixing frame 5 stabilizes the conveying pipe 15 to prevent it from shaking and ensures stable delivery of the solidified material.

[0047] Working principle: First, control the hydraulic rod 4. One end of the hydraulic rod 4 is rotatably connected to the top left side of the tracked vehicle 1, and the other end is rotatably connected to the bulldozer blade 3. The extension and retraction of the hydraulic rod 4 drives the bulldozer blade 3 to move, clearing the surface soil of the excavated section and preparing for subsequent work. Next, start the motor 12. The motor 12 is fixed to the top right side of the fixed frame 5. Its output end drives the main shaft 6, which is fixedly connected to it, to rotate. The main shaft 6 is rotatably connected to the top center of the fixed frame 5. Power is transmitted to the auxiliary shaft 8 through the universal joint 7. One end of the universal joint 7 is fixed to the left end of the main shaft 6, and the bottom end is connected to the auxiliary shaft 8. It can transmit power when there is an angular deviation between the main shaft 6 and the auxiliary shaft 8. The auxiliary shaft 8 is connected to the fixed frame 5. The connecting rod 9, which is rotatably connected to the left side of the outer wall and slidably connected to the inner wall, will rotate with the secondary shaft 8. The planetary gear set 10 fixed at the bottom of the connecting rod 9 will rotate accordingly, thereby driving multiple mixing rods 11 to mix the foundation soil. At the same time, the storage tank 13 plays a role. The storage tank 13 is fixed to the right side of the top of the tracked vehicle 1, and the metering pump 14 connected to the left side of its bottom starts to work, accurately measuring and extracting the solidification material in the storage tank 13. The material is then transported to the annular nozzle 16 through the conveying pipe 15. The annular nozzle 16 is fixed to the outer wall of the planetary gear set 10. During the mixing process of the mixing rods 11, the solidification material is evenly sprayed into the foundation soil, so that the two are fully mixed and solidified in situ.

[0048] Furthermore, when it is necessary to adjust the height of the mixing rod 11 and the annular nozzle 16, the height adjustment mechanism 2 starts to work. The sliding plate 201 is slidably connected to the chute 202 opened on the left side of the outer wall of the fixed frame 5, which allows the sliding plate 201 to move up and down along the direction of the chute 202. At the same time, the bottom end of the telescopic rod 203 fixedly connected to the left side of the outer wall of the fixed frame 5 is connected to the connecting plate 204 fixedly connected to the top of the sliding plate 201. When the telescopic rod 203 is activated, it will extend or shorten according to actual needs. If it is necessary to raise the height of the mixing rod 11 and the annular nozzle 16, the telescopic rod 203 retracts and drives the sliding plate 201 to slide upward along the chute 202. The overall height of the connecting rod 9, planetary gear set 10, mixing rod 11 and annular nozzle 16 connected to the sliding plate 201 rises. Conversely, if it is necessary to lower the height, the telescopic rod 203 extends and pushes the connecting plate 204, so that the sliding plate 201 slides downward along the chute 202, thereby lowering the height of the mixing rod 11 and the annular nozzle 16 to adapt to the needs of soft foundation soil treatment at different depths.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
