Description

Technical Field

[0001] This invention relates to the field of slope reinforcement technology, specifically to a soil slope EICP uniform reinforcement device and method based on pressure transformation. Background Technology

[0002] The stability reinforcement of soil slopes is an important research direction in the fields of civil engineering, geological disaster prevention and control, and ecological restoration. Soil slope reinforcement typically employs biological protection through slope vegetation. Furthermore, to further enhance the reinforcement effect, EICP technology (enzyme-induced calcium carbonate precipitation) is often used. However, existing EICP technologies have two main drawbacks: poor ecological compatibility and insufficient uniformity of reinforcement.

[0003] Specifically, existing EICP technology does not adequately address the issue of uniformity in slurry reinforcement, easily leading to pore blockage during slope reinforcement and resulting in insufficient uniformity. The related equipment used can also damage vegetation (mainly plantlets), resulting in poor ecological compatibility. Furthermore, existing EICP technology is prone to pore blockage in the soil during reinforcement, further contributing to insufficient uniformity.

[0004] For example, Chinese invention patent application CN118686174A describes a method of uniformly reinforcing slopes with grouting by inserting components deep into the soil. This requires inserting the components deep into the soil, making the process extremely labor-intensive. Furthermore, this patent application does not consider the issue of vegetation avoidance on slopes, which could easily lead to damage to the vegetation and poor ecological compatibility.

[0005] For example, the Chinese invention patent application CN115262591A requires large-scale excavation of the soil. Such extensive construction inevitably damages the original landform and environment, and the dissolved oxygen exhibits poor ecological compatibility. Furthermore, the device is relatively fixed and not easily moved to different locations, making its application inconvenient. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a soil slope EICP uniform reinforcement device and method based on pressure transformation, which can solve the problems described in the background art.

[0007] The technical solution to achieve the objective of this invention is as follows: a pressure-transformation-based EICP uniform reinforcement device for soil slopes, comprising an operating rod, an annular suction cup, and a pressure adjustment mechanism, a grouting nozzle, and an ultrasonic transducer mounted on the annular suction cup. One end of the operating rod is connected to the annular suction cup, and an annular groove is provided on the side of the annular suction cup closest to the ground. When the annular suction cup is in contact with the ground, the annular groove and the bottom surface form a closed space. Both the grouting nozzle and the ultrasonic transducer are located within the annular groove. The pressure regulating mechanism is connected to the grouting nozzle, thereby connecting the pressure regulating mechanism to the closed space via the grouting nozzle. The pressure regulating mechanism is used to create negative pressure and high pressure in the closed space via the grouting nozzle. High pressure refers to pressure greater than atmospheric pressure. The grouting nozzle includes several grout outlets and is used to spray grout and clean water onto the ground soil. The ultrasonic transducer is used to generate ultrasonic waves of a preset frequency to excite the cavitation and acoustic flow effects of water in the soil. The micro-jet and shock wave released by the cavitation and acoustic flow effects form a micro-destructive force, which breaks up the dense soil structure in the soil layer, thereby loosening the shallow sediments and opening up the pores, thus increasing the porosity of the shallow soil.

[0008] Furthermore, an annular through hole is provided in the center of the annular suction cup, and an annular groove surrounds the through hole.

[0009] Furthermore, one end of the operating lever is movably connected to the annular suction cup, allowing the operating lever to rotate relative to the annular suction cup.

[0010] Furthermore, the grouting nozzle includes a column, and the grout outlet is located on the column and arranged along the circumference of the column. The grout outlet is a curved arc shape, and each grout outlet is distributed on both sides of the column, so that some grout outlets face the upper slope and the remaining grout outlets face the lower slope.

[0011] Furthermore, the water discharge area S1 of the slurry outlet facing the upper slope and the water discharge area S2 of the slurry outlet facing the lower slope satisfy the following relationship:

[0012] In the formula, k is the viscosity coefficient of the slurry. The slope angle is denoted as .

[0013] Furthermore, the grouting nozzle is connected to an annular suction cup via a bearing, allowing the grouting spray to rotate 360° around its own axis via the bearing.

[0014] Furthermore, the annular suction cup includes a first suction cup portion and a second suction cup portion, which are detachably connected via a magnetic connector.

[0015] Furthermore, the magnetic connector includes a first magnetic component and a second magnetic component, the first magnetic component being mounted on the first suction cup portion and the second magnetic component being mounted on the second suction cup portion. The first magnetic component has a number of recesses, and the second magnetic component has a number of protrusions that match the number of recesses. The protrusions are adapted to the shape of the recesses. When the first magnetic component and the second magnetic component are connected together, one end of the protrusion is embedded in the recess.

[0016] Furthermore, the first suction cup portion is equipped with at least one pressure regulating mechanism, at least one grouting nozzle, and at least one ultrasonic transducer; similarly, the second suction cup portion is also equipped with at least one pressure regulating mechanism, at least one grouting nozzle, and at least one ultrasonic transducer. The pressure regulating mechanism is located at the end of the annular suction cup away from the annular groove, while the grouting nozzle and ultrasonic transducer are located inside the annular groove.

[0017] A method for uniform reinforcement of soil slopes based on pressure transformation using EICP includes the following steps: Step 1: Disassemble and separate the first suction cup portion and the second suction cup portion of the annular suction cup of the reinforcement device, so that the openings of the first suction cup portion and the second suction cup portion are exposed, allowing the vegetation to enter through the through hole on the annular suction cup after passing through the opening. Then, splice the first suction cup portion and the second suction cup portion together and attach the annular suction cup to the ground on the slope, so that the annular groove and the ground form a closed space. Step 2: Spray clean water into the soil in the enclosed space through the grouting nozzle to bring the shallow soil to the preset moisture content; then, set the pressure regulating mechanism to negative pressure mode so that the annular suction cup can suck up the water in the shallow soil through negative pressure. Step 3: Start the ultrasonic transducer and oscillate at the preset frequency to use ultrasonic waves to excite the cavitation effect and acoustic flow effect of water in the soil. The micro-jet and shock wave released by these two effects form a micro-destructive force to break up the dense soil structure in the upper layer, thereby loosening the shallow sediment and opening up the pores, increasing the porosity of the shallow soil. Step 4: Continue to keep the pressure regulating mechanism in negative pressure mode to discharge the impurities formed by the crushing in step 3 along with the clean water, thereby completing the cleaning and dredging of the shallow soil. Step 5: After the shallow soil has been cleaned and cleared, switch the pressure regulating mechanism to high pressure mode and inject EICP grout into the soil through the grouting nozzle.

[0018] The beneficial effects of the present invention are as follows: The present invention has the following technical effects: 1. Innovative combination of negative pressure backflushing and high-pressure grouting: In the negative pressure backflushing stage, ultrasonic waves stimulate the cavitation and acoustic flow effects of water in the soil, thereby breaking up the shallow dense layer. Combined with negative pressure discharge of cleaning fluid (clean water for cleaning), this unclogs the pore channels. In the high-pressure grouting stage, high-pressure airflow drives the grout to penetrate deeper layers, preventing grout accumulation in the shallow layers. The two processes work in cyclical fashion, ensuring uniform distribution of EICP grout at different soil depths, fundamentally solving the problem of "over-reinforcement of the surface layer and under-reinforcement of the deep layer," and significantly improving the overall slope reinforcement effect.

[0019] 2. Ultrasonic vibration can selectively act on shallow soil with high water content, breaking down fine particles and loosening dense structures through cavitation and acoustic flow effects, reducing the source of blockage; negative pressure mode can promptly discharge cleaning fluid containing impurities, preventing particles from accumulating in pores; the high-pressure airflow assistance during the high-pressure grouting stage can promote efficient penetration of grout along the cleared pores, reducing local rapid reactions caused by grout retention, and significantly reducing the probability of pore blockage.

[0020] 3. The detachable circular suction cup uses a magnetic connector to quickly separate and combine the arc-shaped segments. The corresponding arc-shaped segments can be precisely disassembled according to the planting position of the plant. It can be slipped onto the vegetation from one side of the plant, so that it does not need to pass over the plant, avoiding crushing or damaging the vegetation. It is perfectly adapted to the complex ecological environment of the slope scene, taking into account both reinforcement effect and ecological protection.

[0021] 4. The integrated ultrasonic transducer and pressure regulating mechanism form a synergistic pretreatment mechanism: the ultrasonic waves specifically break up the dense layer, and the negative pressure mode replenishes moisture and unclogs pores, creating favorable conditions for subsequent high-pressure grouting; the pressure regulating mechanism can quickly switch modes to achieve rapid connection between "pretreatment and grouting", solving the problem of lack of pretreatment in traditional technology and improving reinforcement efficiency.

[0022] 5. Magnetic connectors improve the efficiency of connecting and disassembling the two suction cups on the arc-shaped section, allowing for quick assembly without tools and adapting to complex slope terrain. The grouting nozzle is rotatable and has a differentiated design of the annular opening area on the side, which can appropriately offset the influence of slope gravity on grout flow and ensure uniform grout distribution under different slopes. 6. The reinforcement device can be flexibly adapted to slopes with different vegetation distribution densities. It can complete the reinforcement of local areas without moving the whole slope, with a wider operating range and stronger adaptability. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-7 As shown, an EICP uniform reinforcement device for soil slopes based on pressure transformation includes an operating rod 2, an annular suction cup 6, and a pressure adjustment mechanism 3, a grouting nozzle 9, and an ultrasonic transducer 10 mounted on the annular suction cup 6. One end of the operating rod 2 is movably connected to the annular suction cup 6, allowing the operating rod 2 to rotate relative to the annular suction cup 6 to adjust its angle, making it easier for the user to grip the operating rod 2. An annular through-hole 12 is provided in the middle of the annular suction cup 6. The annular through-hole 12 allows vegetation (mainly plants) on the slope to pass through the through-hole 12 when the reinforcement device is in contact with the ground during reinforcement operations, preventing damage to the vegetation due to pressure and improving the ecological compatibility of the reinforcement device. An annular groove 11 is provided on the side of the annular suction cup 6 closest to the ground, surrounding the through-hole 12. When the annular suction cup 6 is in contact with the ground, the annular groove 11 and the bottom surface form a closed space.

[0025] Both the grouting nozzle 9 and the ultrasonic transducer 10 are located within the annular groove 11. The pressure regulating mechanism 3 is connected to the grouting nozzle 9, thereby connecting the pressure regulating mechanism 3 to the grouting nozzle 9 and the enclosed space, allowing the pressure regulating mechanism 3 to apply negative pressure to the enclosed space. The pressure regulating mechanism 3 is used to create negative and high pressure in the enclosed space via the grouting nozzle 9. When negative pressure is created, it is used to adsorb liquid containing impurities in the ground soil within the enclosed space, thus allowing the liquid containing impurities to be discharged from above the soil. When high pressure is created, it is used to accelerate the grouting fluid inside the grouting nozzle 9 by blowing high-pressure airflow into the grouting nozzle 9. The grout can be EICP grout or clean water, allowing the grout to be injected into the ground soil more quickly and deeply, enabling the grout to penetrate deeper into the soil layers. By reducing the pressure and injecting under high pressure, stronger permeability of the grout is ensured. In addition, through multiple intermittent infiltrations, the uniformity of the EICP grout's action can be enhanced.

[0026] It is understood that the pressure regulating mechanism 3 has a negative pressure mode and a high pressure mode. In negative pressure mode, the pressure regulating mechanism 3 will create negative pressure in the enclosed space; in high pressure mode, the pressure regulating mechanism 3 will create high pressure in the enclosed space. The pressure regulating mechanism 3 can switch between negative pressure mode and high pressure mode as needed. The ability of the pressure regulating mechanism 3 to implement negative pressure mode and high pressure mode, as well as the switchability between negative pressure mode and high pressure mode, are all existing technologies.

[0027] In addition, in this embodiment, high pressure means that the pressure generated by the pressure regulating mechanism 3 in the enclosed space is greater than atmospheric pressure.

[0028] The grouting nozzle 9 is used to spray grout and clean water onto the ground soil. The grouting nozzle 9 includes several grout outlets 91. The grout and clean water flow out through the grout outlets 91 and are sprayed into the ground soil. By spraying EICP grout, slope reinforcement can be achieved using the EICP method. The ultrasonic transducer 10 is used to generate ultrasonic waves of a preset frequency to excite the cavitation effect and acoustic flow effect of water in the soil. Then, the micro-jet and shock wave released by the cavitation effect and acoustic flow effect form a micro-destructive force. This micro-destructive force breaks up the dense soil structure in the soil layer, thereby loosening the shallow sediments in the soil and opening the pores 12, thus increasing the porosity in the shallow soil layer.

[0029] For example, the grouting nozzle 9 includes a column (not shown in the figure), such as a cylinder. The grout outlet 91 is located on the column and arranged along the circumference of the column. The grout outlet 91 is a curved arc shape, and each grout outlet 91 is distributed on both sides of the column, such that some grout outlets 91 face the upper slope and the remaining grout outlets 91 face the lower slope. The water outlet area S1 of the grout outlet 91 facing the upper slope and the water outlet area S2 of the grout outlet 91 facing the lower slope satisfy the following relationship:

[0030] In the formula, k is the viscosity coefficient of the slurry. The slope angle is denoted as .

[0031] By satisfying the relationship between S1 and S2 as described in the above formula, the aim is to offset or reduce the influence of gravity on grout flow to a certain extent by adjusting the ratio of the sprayed area covered by the grouting nozzle 9 on the upper slope to the sprayed area covered by the lower slope.

[0032] It is understandable that the relationship satisfying the above formula can be the water outlet area S1 of the grout outlet 91 facing the upper slope and the water outlet area S2 of the grout outlet 91 facing the lower slope formed by a single grouting nozzle 9. Alternatively, it can be the water outlet area S1 of the grout outlet 91 facing the upper slope and the water outlet area S2 of the grout outlet 91 facing the lower slope formed by all or a portion of the grouting nozzles 9.

[0033] For example, the grouting nozzle 9 is connected to the annular suction cup 6 via a bearing, so that the grouting spray can be rotated 360° around its own axis via the bearing, thereby adjusting the ratio of the water outlet area S1 of the grout outlet 91 facing the upper slope to the water outlet area S2 of the grout outlet 91 facing the lower slope.

[0034] For example, different sized grout outlets 91 can be provided on different sides of the column of the grouting nozzle 9.

[0035] Understandably, the upper slope refers to the slope located above the grouting nozzle 9, and the lower slope refers to the slope located below the grouting nozzle 9.

[0036] For example, the annular suction cup 6 includes a first suction cup portion 4 and a second suction cup portion 5, which are detachably connected. When the first suction cup portion 4 and the second suction cup portion 5 are joined together, they form an annular suction cup 6. The annular suction cup 6 can be a circular annular suction cup 6.

[0037] For example, the first suction cup portion 4 and the second suction cup portion 5 are detachably connected by a magnetic connector. The magnetic connector includes a first magnetic element 7 and a second magnetic element 8. The first magnetic element 7 is installed in the first suction cup portion 4, and the second magnetic element 8 is installed in the second suction cup portion 5. The first suction cup portion 4 and the second suction cup portion 5 are connected by the magnetic attraction between the first magnetic element 7 and the second magnetic element 8. When disassembly is required, that is, when the first suction cup portion 4 and the second suction cup portion 5 need to be separated, the first magnetic element 7 and the second magnetic element 8 can be separated simply by applying external force.

[0038] For example, the first magnetic component 7 is provided with a plurality of recesses 71, and the second magnetic component 8 is provided with a plurality of protrusions 81 corresponding to the number of recesses. The protrusions 81 are adapted to the shape of the recesses 71. When the first magnetic component 7 and the second magnetic component 8 are connected together, one end of the protrusion 81 is embedded in the recess 71. The protrusions 81 and the recesses 71 ensure precise alignment during connection and facilitate disassembly.

[0039] The first suction cup portion 4 and the second suction cup portion 5 are detachable and can be quickly separated according to the location of the vegetation, so that the vegetation can be placed inside the through hole 12, avoiding crushing or damage to the vegetation.

[0040] For example, the first suction cup portion 4 is provided with at least one pressure regulating mechanism 3, at least one grouting nozzle 9, and at least one ultrasonic transducer 10. Similarly, the second suction cup portion 5 is also provided with at least one pressure regulating mechanism 3, at least one grouting nozzle 9, and at least one ultrasonic transducer 10.

[0041] The pressure regulating mechanism 3 is located at the end of the annular suction cup 6 opposite to the annular groove 11, while the grouting nozzle 9 and the ultrasonic transducer 10 are located within the annular groove 11. The annular groove 11 has a certain depth, thus ensuring that the volume of the enclosed space is within a suitable range.

[0042] For example, the ultrasonic transducer 10 is located on the inner wall of the annular groove 11, and each ultrasonic transducer 10 is distributed along the circumference of the annular suction cup 6, with the ultrasonic transducer 10 facing the center of the annular groove 11.

[0043] For example, it also includes a control panel 1, which is mounted on the control lever 2. The control panel 1 controls the opening and closing of the pressure regulating mechanism 3, the grouting nozzle 9 and the ultrasonic transducer 10, as well as the switching between negative pressure mode and high pressure mode of the pressure regulating mechanism 3.

[0044] like Figure 8 As shown, the present invention also provides a method for uniform reinforcement of soil slopes based on pressure transformation using EICP, applied to the reinforcement device, comprising the following steps: Step 1: Disassemble the first suction cup portion 4 and the second suction cup portion 5 of the annular suction cup 6 of the reinforcement device, so that the openings of the first suction cup portion 4 and the second suction cup portion 5 are exposed, allowing the vegetation (mainly plants) to enter the through hole 12 on the annular suction cup 6 after passing through the openings. Then, splice the first suction cup portion 4 and the second suction cup portion 5 together and attach the annular suction cup 6 to the ground on the slope, thereby forming a closed space between the annular groove 11 and the ground.

[0045] Step 2: Spray clean water into the soil in the enclosed space through the grouting nozzle 9 to make the shallow soil reach the preset moisture content; then, set the pressure regulating mechanism 3 to negative pressure mode so that the annular suction cup 6 can suck up the water in the shallow soil through negative pressure, so as to provide a reaction site for the cavitation effect and acoustic flow effect of water in the soil in the subsequent steps.

[0046] Step 3: Start the ultrasonic transducer 10 and oscillate at a preset frequency to use ultrasonic waves to excite the cavitation effect and acoustic flow effect of water in the soil. The micro-jet and shock wave released by these two effects form a micro-destructive force to break up the dense soil structure in the upper layer, thereby loosening the shallow sediment and clearing the pores 12 to increase the porosity of the shallow soil.

[0047] Step 4: Continue to keep the pressure regulating mechanism 3 in negative pressure mode to discharge the impurities formed by the crushing in step 3 along with the clean water. The clean water is used as a cleaning fluid to complete the cleaning and dredging of the shallow soil and complete the negative pressure backflushing process.

[0048] The annular suction cup 6 contains an inlet / outlet water chamber 13. Impurities and purified water adsorbed by negative pressure are discharged sequentially through the grouting nozzle 9, the inlet / outlet water chamber 13, and the pressure roller adjustment mechanism 3. The use of negative pressure to discharge impurities and purified water is existing technology and will not be elaborated upon here.

[0049] Step 5: After the shallow soil has been cleaned and cleared, switch the pressure regulating mechanism 3 to high-pressure mode and inject EICP grout into the soil through the grouting nozzle 9. The EICP grout can be a urease / urea-CaCl2 solution. The resulting high pressure allows the grouting process to maintain a high-pressure state, and with the driving force generated by the high pressure, the grout can break through the limitations of the shallow soil and achieve efficient penetration into the deeper soil, completing the "high-pressure injection" operation and thus completing the soil reinforcement.

[0050] For example, after step 5, the method further includes: Step 6: Based on the actual uniformity of soil reinforcement in each area, repeat steps 1-5 above to reinforce the soil in all parts of the slope and ultimately achieve uniform soil reinforcement of the slope.

[0051] This invention utilizes a cyclical and synergistic mechanism of "negative pressure adsorption - ultrasonic crushing - high-pressure grouting" to gradually complete the uniform reinforcement of the entire slope area. Each cycle achieves pretreatment of the shallow soil layer and filling of the deep grout layer, effectively avoiding local accumulation of grout and pore blockage, ultimately achieving a good effect of uniform reinforcement of the soil slope.

[0052] The embodiments disclosed in this specification are merely illustrative of one aspect of the invention, and the scope of protection of the invention is not limited to these embodiments. Any other functionally equivalent embodiments fall within the scope of protection of the invention. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the scope of protection of the claims of this invention.
