Description

Automated Soil Lateral Pressure Compensation System and Control Method Technical Field

[0001] This invention relates to the field of soil construction, and in particular to an automated soil lateral pressure compensation system and control method. Background Technology

[0002] With the continuous advancement of urban construction and renewal, underground engineering construction near existing buildings and structures is increasing. However, excavation operations such as foundation pits and tunnels can easily cause displacement and deformation of the surrounding soil, leading to a decrease in soil friction and bearing capacity. This can result in safety hazards such as settlement, tilting, and cracking of nearby buildings and structures. Therefore, the protection of nearby buildings and structures has become a key issue that urgently needs to be addressed in the field of underground construction.

[0003] In existing technologies, the following two main technical solutions are used to address this problem: First, reinforcing the soil beneath existing buildings. This is achieved by injecting chemical grout into designated strata using pressure grouting or high-pressure jet grouting. However, this method requires a certain amount of construction space, and the grouting effect is limited by the building environment and stratum conditions. It is difficult to directly reinforce the area below the building, and the grouting pressure is difficult to control precisely, which can easily cause soil displacement and ground heave, thereby damaging surrounding buildings and pipelines. In addition, if settlement or deformation occurs after reinforcement, reconstruction is required, resulting in a strong response lag. Second, the isolation pile construction method actively isolates construction disturbances by deploying isolation piles. This method is suitable for specific scenarios such as urban centers and areas with limited construction space. However, this method has complex construction processes, long cycles, and high costs. It has strict requirements for construction accuracy and dynamic management. In extremely loose strata or under extreme conditions with unknown obstacles, the isolation effect and pile quality are difficult to guarantee, and it is significantly constrained by site conditions such as underground pipelines.

[0004] In summary, existing technical solutions have drawbacks such as poor controllability, insufficient timeliness, high construction costs, and significant limitations imposed by site or geological conditions. Summary of the Invention

[0005] The purpose of this invention is to provide an automated soil lateral pressure compensation system and control method. Through a segmented layout of multiple independent filling chambers, it can accurately inject filling media to address pressure changes at different soil depths. Simultaneously, through closed-loop control of monitoring and pressurization, it responds to soil pressure changes in real time, improving the timeliness and controllability of soil reinforcement. The specific technical solution is as follows: An automated soil lateral pressure compensation system includes filling components and filling pipes correspondingly arranged within the soil. The end of the filling pipe near the ground is connected to a pressurizing device. The filling component includes multiple filling chambers arranged sequentially, with each chamber forming a cavity. Multiple holes are spaced apart on the filling pipe, each hole corresponding to a cavity in one of the filling chambers. When the monitoring unit within the soil detects a soil pressure change exceeding a warning value, the pressurizing device injects filling media into the corresponding cavity through the filling pipe to compensate for the pressure loss in the soil.

[0006] Furthermore, it also includes a flow switch, which is disposed between the orifice and the filling bladder.

[0007] Furthermore, the filling tube is disposed inside the filling assembly and passes through the cavity of the filling bladder.

[0008] Furthermore, the filling tube is positioned on the outside of the filling assembly.

[0009] Furthermore, the monitoring unit includes an earth pressure sensor and a displacement sensor, both of which are connected to the pressurization device.

[0010] Furthermore, it also includes a sealing tube, which is located at the end of the filling tube away from the pressurizing device, and the filling tube is made of a rigid material.

[0011] Furthermore, the filling medium is a liquid.

[0012] An automated soil lateral pressure compensation control method, employing the aforementioned automated soil lateral pressure compensation system, includes the following steps: determining the area requiring soil lateral pressure compensation, and deploying soil pressure sensors and displacement sensors of the monitoring unit within the area; determining the placement locations of boreholes and filling bags, fabricating filling bags, placing the filling bags into the designated locations through the boreholes, and injecting water to maintain pressure balance in the soil; connecting the monitoring unit to the pressurization device, with the monitoring system capturing real-time data on soil pressure and displacement changes, and adjusting in real-time when the data reaches a warning value, injecting filling medium into the corresponding filling bags as needed to accurately compensate for soil lateral pressure.

[0013] Furthermore, water is used as the filling medium. After the soil pressure and displacement of the soil stabilize, grouting is used to replace the water inside the filling chamber with grout to achieve permanent reinforcement of the soil.

[0014] Furthermore, when the data reaches the warning value and the automatic control fails, the filling is carried out manually by operating the pressurization device.

[0015] The automated soil lateral pressure compensation system and control method of the present invention have the following advantages: 1. Through the segmented layout of multiple independent filling bags, the filling medium can be accurately injected according to the pressure changes at different depths of the soil, effectively avoiding the ground heave caused by excessive local pressure or the deep slippage caused by insufficient pressure. At the same time, through the closed-loop control of monitoring and pressure replenishment, the system can respond to changes in soil pressure in real time, improve the timeliness and controllability of soil reinforcement, continuously maintain the stability of soil pressure around nearby buildings (structures), and reduce the risk of damage to existing buildings and pipelines during construction.

[0016] 2. A flow switch was added between the orifice and the filling bladder, creating an independent control channel for each filling bladder section, upgrading pressure compensation to precise control of each section. Through the linkage between the flow switch and the monitoring system or manual commands, the on / off state and flow rate of the medium in a single filling bladder can be precisely controlled. This ensures that multiple filling bladder sections can independently complete pressure compensation, adapting to the differentiated pressure replenishment needs of complex formations, while effectively avoiding the problem of medium cross-flow between different chambers. Simultaneously, the flow switch can quickly respond to monitoring and early warning signals, instantly starting and stopping medium delivery, further enhancing the timeliness and stability of pressure compensation.

[0017] 3. The filling tube is built into and inserted into the filling chamber. On the one hand, the built-in filling tube provides reliable rigid support for the multi-section continuous filling assembly, which can stably maintain the preset shape and layout of the filling bladder, and solve the problem of pressure compensation failure caused by capsule deformation and displacement during pre-embedding or liquid injection. On the other hand, the direct connection design between the filling tube and the chamber improves the sealing performance, reduces the risk of leakage and cross-flow during the transmission of filling medium, and further enhances the precise volume control capability of a single section in conjunction with the flow switch.

[0018] 4. The external filling tube does not intrude into the internal space of the filling bladder, which avoids damage to the integrity of the bladder caused by the tube-piercing process, reduces the risk of media leakage, and provides more expansion space for the filling bladder to ensure direct and smooth pressure transmission and effectively avoid local pressure imbalance. At the same time, this structure greatly simplifies the construction and subsequent maintenance process. No special processing of the filling bladder is required during pre-embedding, and the filling components do not need to be disassembled when inspecting or replacing the filling tube.

[0019] 5. The monitoring unit includes an earth pressure sensor and a displacement sensor, both of which are connected to the pressurization device. The combination of the earth pressure sensor and the displacement sensor enables comprehensive and seamless monitoring of the soil condition, capturing both pressure changes and tracking displacement trends. This avoids signal deviations or lags caused by monitoring with a single sensor, providing comprehensive and accurate data support for pressure compensation. At the same time, the direct connection between the two sensors and the pressurization device ensures that the monitoring data can be fed back to the execution end in real time, enabling rapid linkage of pressurization operations. Combined with the controller's automatic and manual dual control modes, this ensures the accuracy of pressurization and enables remote sensing and control, reducing the safety risks for personnel entering hazardous areas.

[0020] 6. The sealing tube at the far end of the filling tube can effectively seal the end of the tube body, prevent leakage of the filling medium, ensure the sealing and effectiveness of pressure compensation, and avoid insufficient pressure compensation due to medium loss; while the filling tube made of hard materials such as steel and alloy provides reliable rigid support, which can not only firmly maintain the preset height and layout of the filling bladder, prevent the bladder from deforming or shifting during pre-embedding or liquid injection, but also reduce the difficulty of construction and hole entry and improve the accuracy of pre-embedding.

[0026] To better understand the purpose, structure, and function of this invention, the automated soil lateral pressure compensation system and control method of this invention will be described in detail below with reference to the accompanying drawings.

[0027] As shown in Figures 1 to 4, this invention provides an automated soil lateral pressure compensation system for maintaining stable soil pressure near buildings in a construction area. The system is installed in the lateral soil of the excavated foundation pit 1 and includes a strip-shaped filling component 2 and a filling pipe 6 arranged horizontally within the soil. The filling component 2 and the filling pipe 6 extend downwards along the direction of gravity. The end of the filling pipe 6 near the ground is connected to a pressurizing device 3. The filling component 2 includes multiple filling bladders 4 arranged sequentially, each forming an independent chamber. Multiple holes 5 are spaced apart on the filling pipe 6, and these holes 5 are connected to the chambers of the filling bladders 4 in a one-to-one correspondence. When the monitoring unit 7 in the soil detects a change in soil pressure exceeding a warning value, the pressurizing device 3 injects filling medium into the corresponding chamber through the filling pipe 6 to increase the volume of the corresponding filling bladder 4, compressing the surrounding soil and providing soil lateral pressure compensation, thereby protecting nearby buildings. If the soil pressure continues to decrease, the filling bladder 4 can be further inflated with water to continue supplementing the soil with lateral pressure, thus accurately compensating for the pressure loss of the soil.

[0028] In summary, the automated soil lateral pressure compensation system is specifically installed on the side soil of the excavated foundation pit 1. The system is constructed using elongated filling components 2 arranged horizontally and extending downwards along the direction of gravity, along with filling pipes 6. The filling components 2 include multiple sequentially arranged filling bladders 4, each with an independent chamber. Multiple holes 5 on the filling pipes 6 are connected to each chamber. This, combined with a ground-based pressurizing device 3 and a monitoring unit 7 within the soil, forms a closed-loop control system. When the monitoring unit 7 detects a soil pressure change exceeding a warning value, the pressurizing device... 3. The filling medium is precisely injected into the corresponding depth chamber through the filling pipe 6, causing the corresponding filling bladder 4 to increase in volume. With the segmented control design of multiple independent chambers, the pressure loss of soil at different depths can be accurately compensated, avoiding ground heave or deep slippage caused by pressure imbalance. The soil pressure around the construction area and adjacent buildings is kept stable in real time, improving the controllability and timeliness of soil reinforcement. At the same time, the low-cost filling medium and safe pressure compensation method reduce the risk of damage to existing buildings and pipelines, ensuring construction safety and building stability.

[0029] It should be noted that the filling medium can be a gas, liquid, or other physical material. By injecting the filling medium, the volume of the filling capsule 4 expands to compress the soil, thereby compensating and adjusting the lateral pressure of the soil. In this embodiment, water is preferred as the filling medium. This is not only because water is inexpensive, readily available, and its usage can be precisely controlled by limiting the flow through the capsule, significantly reducing construction costs, but also because it is non-consolidating, allowing for repeated pressurization to match the dynamic changes in soil pressure, avoiding the lag and waste problems of grouting. At the same time, the stability of water can reduce fluctuations during pressure transmission, improving pressurization accuracy. Subsequently, water can be replaced with grout through a safe and controllable grout replacement method to achieve permanent reinforcement. This avoids the inaccurate pressurization caused by the compressibility of gaseous media and solves the hidden dangers of chemical grout easily leaking and damaging pipelines, enhancing the controllability and safety of the system and reducing system costs.

[0030] The filling bladder 4 is made of high-strength, high-pressure resistant deformable material. Its volume can be customized according to the target soil lateral pressure compensation requirements. Understandably, under the premise that the injection pressure is adapted to the soil working conditions, the larger the volume of the filling bladder 4, the more filling medium it can hold, and the stronger the corresponding soil lateral pressure compensation capacity, which can more fully adapt to the soil pressure compensation requirements of different depths and different pressure loss degrees.

[0031] Furthermore, multiple flow switches are included, with one flow switch corresponding to each group of holes 5 and filling bladders 4. This creates an independent control channel on each filling bladder 4, enabling independent water injection operations. By individually controlling each flow switch, water can be injected and pressurized into the filling bladder 4 at a specified depth, thus achieving accurate compensation for lateral pressure on soil at different depths. Simultaneously, through linkage with the automated monitoring unit 7 or manual control commands, the on / off state and flow rate of the filling medium can be precisely controlled, achieving accurate metering and real-time adjustment of the water injection volume for each filling bladder 4. The flow switches not only ensure that each filling bladder 4 independently completes pressure compensation, effectively avoiding ground heave caused by excessive pressure in a single section or deep slippage caused by insufficient pressure, adapting to the differentiated pressure replenishment needs of complex strata, but also prevent media cross-flow between different chambers, ensuring the controllability and stability of the pressure replenishment process. Furthermore, in conjunction with the early warning signals of the monitoring system, media delivery can be quickly started and stopped, further enhancing the timeliness of pressure compensation.

[0032] Preferably, as shown in Figure 2, the filling tube 6 is arranged inside the filling component 2 and penetrates through the chamber of the filling bag 4. Therefore, by virtue of the support characteristics and through-layout of the filling tube 6, on the one hand, it provides rigid support for the multi-section continuous filling component 2, effectively maintaining the preset shape and layout of each filling bag 4, avoiding the pressure compensation failure caused by the deformation and offset of the filling bag 4 during the pre-burial or liquid injection process, and at the same time simplifying the construction process, facilitating quick and accurate pre-burial through drilling; on the other hand, the built-in filling tube 6 can make the connection between the hole part 5 and each chamber more direct and have better sealing performance, reducing the risk of leakage or cross-flow of the filling medium during transmission, and further strengthening the accurate quantity control and independent pressure compensation ability of a single filling bag 4 in cooperation with the independent flow switch.

[0033] The above structure adapts to the different pressure compensation requirements of the upper sand layer and the lower clay layer, avoids the problem that the external pipeline is easily damaged by soil disturbance, and at the same time can improve the overall stability and durability of the system, ensuring the accurate transmission and efficient response of pressure compensation.

[0034] Preferably, as shown in Figure 4, the filling tube 6 is arranged outside the filling component 2, so as to accurately convey the filling medium without invading the internal space of the filling bag 4. On the one hand, this structure can avoid the influence of the filling tube 6 penetrating the chamber on the integrity of the filling bag 4, reducing the risk of medium leakage, and at the same time reserving a more sufficient expansion space for the filling bag 4, ensuring more direct and smooth pressure transmission, adapting to the different pressure compensation requirements of complex strata, and effectively avoiding local pressure imbalance problems; on the other hand, it simplifies the construction and maintenance processes. When pre-burying, there is no need to process the filling bag 4 by threading the tube. When overhauling or replacing the filling tube 6 later, there is no need to disassemble the filling component 2, reducing the construction difficulty and maintenance cost, and can also reduce the secondary disturbance to the soil, further ensuring the stability of the soil around adjacent buildings.

[0035] Furthermore, the monitoring unit 7 can be arranged in the soil or on the filling component 2. The monitoring unit 7 includes an earth pressure sensor and a displacement sensor. Both the earth pressure sensor and the displacement sensor are connected to the pressurizing device 3. Furthermore, both the monitoring unit 7 and the pressurizing device 3 are connected to the automatic monitoring system, which can display the change of the soil side pressure in real time, automatically control or manually control the water injection volume to compensate the soil pressure. At the pressurizing device 3, water injection operation and the display of the earth pressure around the filling bag 4 can also be carried out. By means of the monitoring unit 7, the data of the soil pressure and displacement changes are captured in real time. After being processed by the automatic monitoring system, the indoor real-time display and the linkage control of the pressurizing device 3 are synchronously realized. It not only supports the system to automatically and accurately match the water injection volume according to the warning value to compensate the soil pressure, but also retains the redundant control mode of directly manually operating the water injection at the pressurizing device 3 and checking the earth pressure around the filling bag 4. The automatic monitoring unit 7 can realize remote perception and control, reducing the safety risk of personnel.

[0036] It is understandable that those skilled in the art can appropriately increase the number of earth pressure sensors in accident-prone areas to collect earth pressure data changes during construction and transmit them to the data acquisition device in real time.

[0037] Furthermore, it also includes a sealing tube, which is set at the end of the filling tube 6 away from the pressurizing device 3. The sealing tube can seal the end of the filling tube 6, effectively preventing leakage of the filling medium and ensuring the sealing and effectiveness of pressure compensation. At the same time, the filling tube 6 is made of hard materials such as steel and alloy, providing reliable rigid support. It can not only firmly maintain the preset height and layout posture of the filling bladder 4, avoiding deformation and displacement of the bladder during pre-embedding or liquid injection, but also reduce the difficulty of construction and improve the accuracy of pre-embedding.

[0038] It is understandable that extending the embedment length of the filling bladder 4 can expand the pressure compensation coverage range, while increasing the number of sections can refine the pressure control of strata at different depths. Moreover, the more sections there are, the better they can adapt to the differentiated pressure compensation needs of complex strata, further improving the accuracy of pressure compensation.

[0039] As shown in Figure 5, this invention also provides an automated soil lateral pressure compensation control method. The method employs the aforementioned automated soil lateral pressure compensation system and specifically includes the following steps: First, determine the area requiring soil lateral pressure compensation. Then, deploy earth pressure sensors and displacement sensors of the monitoring unit 7 within this area (they can be placed in the soil or on the filling component 2; the number of earth pressure sensors can be appropriately increased in areas prone to accidents). Next, determine the placement positions of the borehole and the filling bag 4, specify the length specifications of the filling bag 4, and complete its fabrication. Then, place the filling bag 4 into the designated position through the borehole and inject water to maintain pressure balance in the soil. Afterward, connect the monitoring unit 7 to the pressurizing device 3. The monitoring system captures soil pressure and displacement changes in real time. When the data reaches the warning value, real-time adjustments are made. Water is injected into the filling bag 4 at the designated section as needed to accurately compensate for soil lateral pressure. Once the soil pressure and displacement of the stratum are stable, grouting is used to replace the water inside the filling bag 4 with grout, achieving permanent soil reinforcement. When the data reaches the warning value and the automatic control fails, the pressurizing device is manually operated to fill the bag, providing the system with safety redundancy.

[0040] The automated soil lateral pressure compensation system and control method provided by this invention have the following advantages: 1. Safe and reliable, avoiding damage to existing buildings and structures during the reinforcement process. This system utilizes the principle of water-filled compression in multi-section filling bladders to accurately compensate for the lateral pressure of the soil at designated locations, effectively maintaining the original properties of the soil. It avoids soil instability caused by pile excavation and prevents ground heave and grout leakage into pipelines caused by uncontrolled grouting. Compared with conventional jet grouting and sleeve valve grouting processes, it offers greater controllability and significantly reduces the risk of damage to existing buildings and structures during construction.

[0041] 2. Excellent timeliness, providing continuous and uninterrupted protection for buildings and structures. The system uses water as the pressure transmission medium, which does not solidify, allowing pressure compensation to be repeated continuously. Furthermore, with the addition of automated devices, it can automatically compensate for soil pressure loss based on monitoring data, providing a fast response and timely compensation for insufficient soil lateral pressure, ensuring the continuity of protection.

[0042] 3. Low implementation cost and high cost-effectiveness. The system uses inexpensive water as the filling medium, and thanks to the flow-limiting effect of the filling bladder, the water consumption is extremely low, which greatly reduces the overall cost of materials and construction, giving it a high cost-effectiveness advantage.

[0043] 4. Grouting reinforcement during the risk elimination phase is safer, more controllable, and more effective. Once the soil pressure and displacement are stable and the construction risks are eliminated, the system adopts a grout replacement method to replace the water in the filling chamber 4 with grout to achieve permanent reinforcement. This replacement method is safe to operate, highly controllable, and can effectively ensure the uniformity of grouting and improve the reinforcement effect.
