Technical Field
[0001] This utility model relates to a soil moistening device with adjustable multi-directional permeability, belonging to the field of foundation treatment technology. Background Technology
[0002] A soil humidification device is an engineering equipment specifically designed to address the problem of insufficient moisture content in foundation soil. It is widely used in building foundation treatment, roadbed reinforcement, slope stabilization, and other scenarios. Its core principle is to use an intelligent control system to evenly deliver water or a specific humidification solution into the foundation soil through distributed pipelines. Combined with infiltration and wetting effects, it increases the soil's moisture content, improves the soil's physical and mechanical properties, and avoids potential problems such as foundation settlement and cracking caused by soil particle drying and shrinkage.
[0003] In foundation treatment engineering, traditional soil humidification devices mostly adopt a fixed-direction permeation structure, which can only achieve single-depth or unidirectional humidification. This makes it difficult to adapt to the complex structure of layered foundations, resulting in insufficient humidification of deep soil or excessive humidification of shallow soil. The device position needs to be adjusted multiple times to cover the target area, which is not only cumbersome to operate, but also affects the humidification effect due to repeated disturbance of the foundation soil, thereby reducing the humidification efficiency.

[0018] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0019] like Figure 1 - Figure 4 As shown, the adjustable multi-directional permeable foundation soil moistening device provided in this embodiment includes a base plate 1, a support frame 2 fixedly installed on the base plate 1, a transmission mechanism 3 provided on the support frame 2, and a permeation mechanism 4 installed on the transmission mechanism 3. The transmission mechanism 3 includes a drive motor 31. A threaded rod 32 is fixedly connected to the output end of the drive motor 31. A threaded slider 33 is threadedly connected to the threaded rod 32. A guide rod 34 is provided on one side of the threaded rod 32. A sliding block 35 is slidably connected to the guide rod 34. The sliding block 35 and the threaded slider 33 are connected through a lifting plate 36. A drive sprocket 37 is fixedly connected to the end of the threaded rod 32 away from the drive motor 31. Several driven sprockets 38 are evenly distributed on one side of the drive sprocket 37. The driven sprockets 38 are all provided on the permeation mechanism 4. The driven sprockets 38 are connected to the drive sprocket 37 through a chain 39. The infiltration mechanism 4 includes several infiltration pipes 41. A telescopic assembly 42 is installed above each infiltration pipe 41. The infiltration pipes 41 and the telescopic assembly 42 are connected by a bearing 43. A conical soil-breaking head 44 is fixedly connected to the lower end of each infiltration pipe 41. Three sets of infiltration holes 45 are provided in the lower half of each infiltration pipe 41. The diameter of the holes in the three sets of infiltration holes 45 increases sequentially from top to bottom. Each set of infiltration holes 45 contains four holes, which are evenly distributed around the circumference of the infiltration pipe 41, with a 90° spacing between adjacent holes. When the drive motor 31 starts, it drives the threaded rod 32 to rotate. The threaded slider 33 moves along the threaded rod 32, and simultaneously the sliding block 35 slides along the guide rod 34, causing the lifting plate 36 to rise and fall smoothly, adjusting the soil penetration depth of the infiltration mechanism 4. At the same time, the drive sprocket 37 rotates with the threaded rod 32. The chain 39 drives each driven sprocket 38 to rotate synchronously (the number and spacing of the driven sprockets 38 are set according to actual usage requirements), so that the permeation pipe 41 rotates under the support of the bearing 43. The length is adjusted with the telescopic component 42. The conical soil-breaking head 44 at the lower end of the permeation pipe 41 is easy to insert into the foundation soil. The three sets of permeation holes 45 in the lower half are radially increasing, which realizes multi-directional permeation during rotation. The small holes in the upper part are suitable for shallow and precise humidification, while the large holes in the lower part enhance the deep permeation capacity. The permeation holes 45 in each group of four permeation holes 45 are distributed at 90° to ensure uniform diffusion of water in the horizontal direction, adapting to different soil layer structures. This achieves multi-depth and multi-directional uniform humidification of the foundation soil, solving the problems of limited permeation range and uneven humidity distribution of traditional devices, thereby improving humidification efficiency and uniformity. The edges of the permeation holes 45 are chamfered to create a smooth transition structure at the opening. When sand and gravel in the soil rotate with the permeation pipe 41 or when water flows into the opening, they can slide smoothly along the arc surface, avoiding being stuck by sharp edges and forming a blockage point. Depending on the usage requirements, a mesh can be installed inside the permeation holes 45 to directly intercept hard particles larger than the opening, preventing the opening of the permeation holes 45 from being blocked and affecting the water flow. At the same time, the smooth edges reduce the frictional resistance between the particles and the opening. Combined with the dynamic flushing generated by the rotation of the permeation pipe 41, this ensures that the three sets of permeation holes 45 with different diameters remain unobstructed, ensuring uniform water flow at all depths and directions, reducing humidification imbalance caused by local blockage, extending the equipment's trouble-free operating time, and thus reducing the frequency of cleaning and maintenance.
[0020] Furthermore, such as Figure 1 - Figure 4As shown, the telescopic assembly 42 includes a telescopic outer rod 421 and a telescopic inner rod 422. The telescopic outer rod 421 is sleeved on the outside of the telescopic inner rod 422, and two symmetrically distributed limiting keyways 423 are formed inside the telescopic outer rod 421. Limiting key blocks 424 are fixedly installed on both outer surfaces of the telescopic inner rod 422. The limiting key blocks 424 are slidably disposed inside the limiting keyways 423. A limiting block 425 is fixedly connected to one end of the telescopic inner rod 422 located at the telescopic outer rod 421. The outer diameter of the telescopic inner rod 422 is smaller than the inner diameter of the upper outlet of the telescopic outer rod 421. The end of the telescopic inner rod 422 away from the limiting block 425 is fixedly connected to the driven sprocket 38. The bearing 43 is installed inside the lifting plate 36, and the outer ring of the bearing 43 is fixedly connected to the lifting plate 36. The inner ring of the bearing 43 is fixedly connected to the permeation pipe 41 and the telescopic outer rod 421. Flow channels 426 are opened inside both the telescopic outer rod 421 and the telescopic inner rod 422. The telescopic inner rod 422 is connected to the telescopic outer rod 421 via the limiting key block 424. The sliding mechanism within the limiting keyway 423 prevents the two from separating, allowing for length extension and retraction to adjust the soil penetration depth of the permeation pipe 41. Simultaneously, the driven sprocket 38 rotates, driving the inner telescopic rod 422 to rotate. Through the cooperation of the limiting keyway 423 and the limiting key block 424, the outer telescopic rod 421 rotates synchronously. The rotation is then transmitted through the bearing 43, causing the permeation pipe 41 to rotate. Meanwhile, the flow channel 426 ensures that water flows from the inner telescopic rod 422 to the outer telescopic rod 421 and then into the permeation pipe 41. Since the outer ring of the bearing 43 is fixed to the lifting plate 36, and the inner ring is fixed to the permeation pipe 41 and the outer telescopic rod 421, rotational stability and firm support can be guaranteed. Furthermore, a seal is provided at the connection between the inner ring of the bearing 43 and the permeation pipe 41 and the outer telescopic rod 421 to prevent water leakage in the flow channel 426, thus meeting the humidification needs of multiple depths and directions.
[0021] Furthermore, such as Figure 1 - Figure 4 As shown, the inner side of the support frame 2 has two symmetrically distributed transmission grooves 5. The drive motor 31 is fixedly installed on the inner bottom surface of one of the transmission grooves 5. The end of the threaded rod 32 away from the drive motor 31 is rotatably connected to the inner top surface of one of the transmission grooves 5. The guide rod 34 is fixedly installed inside the other transmission groove 5. The threaded slider 33 and the sliding block 35 are respectively slidably arranged inside the two transmission grooves 5. The transmission grooves 5 provide installation space for the drive motor 31, the threaded rod 32 and the guide rod 34, so that the threaded slider 33 and the sliding block 35 can slide stably in the groove, restrict their radial displacement, ensure the vertical movement of the lifting plate 36, improve the structural rigidity and stability, avoid shaking or deviation during transmission, and ensure the precise lifting of the permeation mechanism 4, thereby achieving precise control of the wetting depth of the foundation soil.
[0022] Furthermore, such as Figure 1 - Figure 4As shown, a transmission box 6 is fixedly connected to the upper end of the support frame 2. Several driven sprockets 38 are all set inside the transmission box 6. The transmission box 6 provides a closed protective space for the driven sprockets 38 and the chain 39 to prevent dust, soil and other debris from getting into the transmission components and causing jamming. At the same time, it fixes the position of the driven sprockets 38, ensures the accurate transmission of the chain 39, reduces external interference, and thus improves the operational stability and lifespan of the transmission mechanism 3, thereby ensuring the synchronous operation of the permeation mechanism 4.
[0023] Furthermore, such as Figure 1 - Figure 4 As shown, a water tank 7 is fixedly installed on the base plate 1. The water tank 7 has a water inlet 8, and a water supply pipe 9 is fixedly connected to the upper end of the water tank 7. A water pump 10 is installed on the water supply pipe 9, and a branch pipe 11 is fixedly connected to the end of the water supply pipe 9 furthest from the water tank 7. Several evenly distributed connectors 12 are fixedly connected to the branch pipe 11, and each connector 12 is rotatably connected to one end of the telescopic inner rod 422. The water tank 7 stores water through the water inlet 8 and has a level gauge inside to monitor the water level in real time to ensure sufficient water supply. After the water pump 10 is started, water is transported through the water supply pipe 9 to the branch pipe 11. Flow control is implemented on each branch of the branch pipe 11. The valve can precisely adjust the amount of water distributed to each connector 12 according to the humidification needs of different areas of the foundation soil. Since the connector 12 is rotatably connected to the telescopic inner rod 422, it can ensure that the water flow enters the flow channel 426 of the telescopic inner rod 422 stably, without affecting the rotational transmission of the telescopic inner rod 422. The water flow is then transported sequentially through the flow channels 426 of the telescopic inner rod 422 and the telescopic outer rod 421 to the infiltration pipe 41, and finally infiltrates into the foundation soil through the infiltration hole 45. This achieves a closed-loop water supply from water source storage, quantitative transportation to precise distribution, adapting to the differentiated humidification needs of multiple areas, thereby improving the uniformity and controllability of humidification.
[0024] Furthermore, such as Figure 1 - Figure 4 As shown, a through groove 13 is provided on the base plate 1. The through groove 13 is located below and corresponds to several permeation pipes 41. A shielding plate 14 is fixedly installed on the upper surface of the base plate 1, and a control panel 15 is fixedly installed on one side of the support frame 2. The through groove 13 corresponds to the position of the permeation pipe 41, providing a precise channel for its insertion into the soil and ensuring vertical insertion into the foundation soil. The shielding plate 14 can not only block the soil clods splashed during the operation of the cone-shaped soil breaking head 44, but also intercept the mud and water splashed during humidification, keeping the working environment clean. The control panel 15 centrally controls the operation of the equipment, thereby improving the convenience of operation and the standardization of the site, and helping to carry out efficient humidification of the foundation soil.
[0025] like Figure 1 - Figure 4 As shown in the figure, the principle of the adjustable multi-directional permeability foundation soil moistening device provided in this embodiment is as follows: During operation, the operator starts the equipment via control panel 15. Water stored in water tank 7 through water inlet 8 is pumped by water pump 10 and delivered along water pipe 9 to distribution pipe 11. Distribution pipe 11 precisely distributes water according to the needs of different areas of the foundation soil through flow control valves of each branch pipe. Then, the water is injected into the flow channel 426 of telescopic inner rod 422 through connector 12, which is rotatably connected to telescopic inner rod 422, while avoiding interference with the rotational transmission of telescopic inner rod 422. Then, drive motor 31 is started, driving threaded rod 32 to rotate in transmission groove 5, causing threaded slider 33 to move along threaded rod 32. At the same time, sliding block 35 slides synchronously along guide rod 34, driving lifting plate 36 to rise and fall, adjusting the penetration depth of permeation mechanism 4. Meanwhile, the drive sprocket 37 at the other end of threaded rod 32 rotates with it, driving all driven sprockets 38 to rotate synchronously in transmission box 6 through chain 39, thereby making the driven sprockets 38 fixed. The inner telescopic rod 422 rotates, and the inner telescopic rod 422 cooperates with the limiting keyway 423 of the outer telescopic rod 421 through the limiting key block 424, driving the outer telescopic rod 421 to rotate synchronously. Then, through the bearing 43, the permeation pipe 41 is guided by the through groove 13 and smoothly inserted into the foundation soil with the conical soil breaking head 44 and rotates. During the rotation of the permeation pipe 41, the three sets of permeation holes 45 with increasing diameter from top to bottom in the lower half realize multi-directional permeation. The small holes in the upper part are suitable for shallow and precise humidification, and the large holes in the lower part enhance the deep permeation capacity. The water in the flow channel 426 seeps into the foundation soil through the permeation holes 45 through the outer telescopic rod 421 and the permeation pipe 41. At the same time, the shielding plate 14 blocks the splashing of soil and mud during the operation, and finally realizes the uniform and controllable humidification of the foundation soil at multiple depths and in multiple directions, solving the problems of limited permeation range and uneven humidity distribution of traditional devices, thereby improving the humidification efficiency and uniformity.
