Description

Technical Field

[0001] This utility model belongs to the field of sand and soil solidification technology, and relates to a portable sand and soil solidification device for engineering applications. Background Technology

[0002] In desert regions and in engineering projects requiring the stabilization of loose soils such as sand and loess, traditional stabilization methods face numerous challenges. Firstly, physical stabilization methods, such as gravel barriers and ordinary cement slab barriers, while effective in curbing wind and sand erosion to some extent, also have obvious limitations. These methods not only require large-scale material transportation, increasing logistics costs, but also involve cumbersome construction processes and high labor demands, thus driving up overall project costs. Furthermore, the stabilization efficiency and effectiveness of physical stabilization methods are often unsatisfactory, with long stabilization times and curing periods, which is undoubtedly a significant obstacle for projects where quick results are crucial.

[0003] On the other hand, while the emerging microbial soil stabilization technology boasts significant environmental advantages and is considered a green and sustainable stabilization method, it has also revealed some problems in practical applications. The basic principle of microbial soil stabilization is to utilize specific microorganisms that grow and reproduce in the sand, using their metabolic activities to produce binding substances that tightly bind sand particles together, thus achieving stabilization. However, the uniformity of the mixing of the microbial solution and nutrient solution becomes a key factor restricting the stabilization effect. Uneven mixing can lead to uneven distribution of microorganisms in the sand, with some areas having too many or too few microorganisms, thus affecting the overall stabilization effect. Furthermore, the growth and metabolism of microorganisms are also affected by various environmental factors such as temperature, humidity, and pH value, and changes in these factors can adversely affect the stabilization effect.

[0004] Therefore, there is an urgent need for a new type of sand and soil solidification device that can achieve uniform solidification of sand and soil, high construction efficiency, low cost and strong environmental adaptability, so as to meet the urgent needs of desertification control and various engineering projects for solidification of loose soil.

[0057] like Figure 4 As shown, the curing and fusion box assembly 4 includes a first infusion pipe 4-1, a second infusion pipe 4-2, a fixed shell 4-5, and a liquid mixing box 4-4;

[0058] The first infusion tube 4-1 and the second infusion tube 4-2 are disposed inside the fixed shell 4-5. One end of the fixed shell 4-5 is fixedly connected to the fusion box by threads. The other end of the fixed shell 4-5 is bonded to the bottom of the microbial liquid supply component 2 and the cementing liquid supply component 3 by sealant.

[0059] The liquid mixing tank 4-4 is provided with an installation hole. The first infusion tube 4-1 and the second infusion tube 4-2 pass through the installation hole and are inserted into the liquid mixing tank 4-4. The liquid mixing tank 4-4 is equipped with a spray head 4-3. The spraying device 1 adopts the working principle of a press-type sprayer. The liquid switch on the spraying device 1 is connected to the spray head 4-3.

[0060] The spraying device 1 is sealed to the liquid mixing tank 4-4;

[0061] The spraying device 1 adopts a press-type spray bottle mechanism, which mainly consists of the following components:

[0062] The bottle body uses a liquid mixing tank: used to store liquids, usually made of plastic or glass.

[0063] Injector head: Responsible for atomizing and spraying the liquid; it contains fine nozzles. The injector head is installed at the liquid mixing tank and connected to the mixed liquid in the tank via a pipe.

[0064] Press the handle: Press to drive the liquid to spray out.

[0065] Straw: Used to connect the liquid in the liquid mixing tank to the spray head, responsible for conveying the liquid. The spray device 1 includes two straws. One straw inflates the liquid mixing tank by pressing the handle, and the other straw is connected to the spray head at one end and extends into the liquid in the liquid mixing tank at the other end. The liquid in the liquid mixing tank is sprayed out by opening and closing the valve.

[0066] Valve system: controls liquid flow and ensures unidirectional delivery.

[0067] Sealing ring: Prevents liquid leakage and ensures a tight seal.

[0068] Adjustment knob: Used to adjust the spray mode.

[0069] Dust cover: Protects the nozzle from contamination.

[0070] In one preferred embodiment, the spraying device 1 can be applied to this patent by referring to the working principle of the improved structure of the pneumatic sprayer in document CN203245061U to achieve the spraying effect;

[0071] In one preferred embodiment, the spraying device 1 can adopt the working principle of a sprayer as described in document CN104338637A and apply it to this patent to achieve the spraying effect;

[0072] The spraying device 1 operates on the same principle as a press-type sprayer. In use, the valves installed at the first conduit 2-6 and the second conduit 3-4 are opened, allowing liquid to flow into the liquid mixing tank 4-4, which serves as the body of the press-type sprayer. When the handle of the spraying device 1 is pressed, the gas inside the liquid mixing tank 4-4 is compressed, increasing the internal pressure. Because the internal pressure of the liquid mixing tank 4-4 becomes greater than the external atmospheric pressure, the mixed liquid inside the liquid mixing tank 4-4 is forced out through the pipe and spray head 4-3 by the press-on switch, forming a spray. The faster the handle is pressed, the greater the gas pressure inside the liquid mixing tank 4-4, and thus the greater the flow rate of the sprayed liquid.

[0073] Microbial inoculum and cementing solution are stored in separate storage boxes. When sand needs to be solidified, the microbial inoculum is transported to a liquid mixing tank via a first conduit, while the cementing solution is simultaneously transported to the same tank via a second conduit. In the liquid mixing tank, the microbial inoculum and cementing solution mix to form a solidified solution. Then, the spraying device is activated, spraying the mixed solidified solution onto the sand requiring solidification through a nozzle.

[0074] The microbial inoculant and the cementing agent work together to cause a solidification reaction in the sand, thus achieving the desired solidification. The operator aligns the solidification device with the sand surface to be solidified, activates the valve, and the microbial inoculant and cementing agent are delivered to the liquid mixing tank 4-4 of the solidification and fusion chamber for mixing. The mixed solidified liquid is then evenly sprayed onto the sand surface via the spraying device 1, driving the spray head 4-3, completing the solidification process. This mixing of the two solutions ensures thorough and uniform mixing of the microbial inoculant and cementing agent, avoiding uneven solidification in certain areas. The spraying operation is simple and quick, rapidly and evenly spraying the mixture onto the sand surface, improving construction efficiency. After solidification, a relatively uniform and dense sand sample is obtained, which is easy to carry and operate.

[0075] 1. High-efficiency solidification: Through the uniform mixing of microbial solution and nutrient solution, the formation of calcium carbonate in sand can be rapidly promoted, forming a stable solidification layer, significantly improving the compressive strength and stability of sand, and effectively preventing soil erosion.

[0076] 2. Portability: The device has a compact design, making it easy to carry and operate. It is especially suitable for use in desert areas and engineering sites, eliminating the need for complex equipment and a large workforce, thus greatly improving construction efficiency.

[0077] 3. Environmental friendliness: The microbial inoculant and cementitious liquid used are both environmentally friendly materials that do not pollute the environment, meet the requirements of green construction, and help protect the ecological environment.

[0078] 4. Low cost: Compared with traditional gravel sand barriers and ordinary cement board sand barriers, the material and construction costs of this device are significantly reduced, making it more economical and suitable for large-scale promotion and application.

[0079] 5. Easy to operate: The design of the spraying device makes operation simple and quick. Simply pull the spray handle to mix and spray the microbial liquid and cementing liquid, which greatly simplifies the construction process and improves work efficiency.

[0080] In summary, this invention not only solves the problems of uneven solidification, low construction efficiency, high cost, and poor environmental adaptability in existing sand and soil solidification methods, but also provides an efficient, environmentally friendly, economical, and portable sand and soil solidification solution, which has significant practical application value and broad application prospects.
