Description

Technical Field

[0001] This invention relates to the field of anti-seepage wall casting technology, and more particularly to the field of adaptive pressurized casting technology, specifically to an intelligent adaptive casting system and casting process. Background Technology

[0002] The underwater pouring of concrete for seepage-proof walls commonly employs the tremie method. Its core principle relies on the superpressure created by the concrete's own weight within the tremie pipe to displace the mud in the trench, thus forming a complete concrete wall. However, this traditional method, dependent on pure gravity, has significant limitations. First, it places extremely stringent requirements on the depth of the tremie pipe embedded in the poured concrete: too shallow a depth can cause mud to be drawn in from the bottom of the tremie pipe, creating mud inclusion defects; too deep a depth increases the resistance to the upward flow of concrete, easily leading to a "cast pipe" accident where the concrete blocks the tremie pipe. Therefore, regulations mandate that the tremie pipe depth must be strictly controlled between 2 and 6 meters, which highly depends on the experience and responsibility of the construction personnel.

[0003] Secondly, traditional construction methods require interrupting the concrete supply to disassemble the guide pipe sections when lifting (pulling out) the guide pipe. This process is not only cumbersome, but more importantly, interrupting the supply instantly reduces the internal pressure of the guide pipe, easily causing slurry from the trench to flow back into the guide pipe and mix with the concrete, resulting in serious quality problems such as mud inclusions in the wall and broken piles. Furthermore, determining the timing of lifting relies entirely on manual, timed measurements of the concrete surface, which is prone to lag and error, further increasing the risk of wall quality defects due to improper depth control or slurry backflow. Therefore, there is an urgent need for a seepage barrier wall construction system and method that can achieve continuous, controllable, and high-quality pouring. Summary of the Invention

[0004] To address the challenges of precise control over pipe extraction timing and height in existing anti-seepage wall construction techniques, which can lead to leakage, mud inclusion, and pipe casting issues, this application provides an intelligent adaptive casting system and process. By abandoning gravity grouting and adopting pressure grouting, coupled with the use of valve assemblies, the precision requirements for pipe extraction are significantly reduced. Furthermore, pipe extraction can be performed without interrupting the casting process, greatly improving efficiency and continuity. This invention uses continuous mud recovery to determine the concrete layer thickness at the bottom of the anti-seepage wall, thereby calculating the burial depth of the casting pipe. This ensures the accuracy of the pipe burial depth without affecting mud recovery, achieving multiple benefits.

[0005] Compared to existing pouring systems, the pouring system used in this invention significantly reduces the use of sensors. Instead, it uses the amount of mud recovered to infer the concrete burial depth, eliminating the need for deep-seated sensors. This solves the problem that existing sensors are prone to signal distortion and large control errors when collecting signals in deep, high-pressure mud environments.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: An intelligent adaptive pouring system for adaptive pouring of seepage-proof walls includes: A concrete pressure conveying system includes a concrete supply mechanism, a concrete distributor, a pressure conveying mechanism, and a distribution valve control mechanism. The pressure conveying mechanism pressurizes the concrete in the concrete distributor and then injects it into the anti-seepage wall trench through the distribution valve control mechanism. The distribution valve control mechanism includes n pouring pipe valve groups, where n≥1. The liquid level monitoring and mud recovery system includes a tank opening liquid level sensor installed in the anti-seepage wall trench near the opening to detect the real-time liquid level of the mud, and a mud recovery controller to receive the data from the tank opening liquid level sensor and control the mud recovery pump to pump the mud in the anti-seepage wall trench into the mud storage tank. The intelligent pipe-pulling system includes a control center and a lifting execution system. The control center calculates the current burial depth of the pipe by receiving real-time data from the liquid level sensor and the mud recovery controller. The system sends lifting control commands to the lifting execution reminder. The lifting execution system includes multiple lifting mechanisms for lifting the pouring pipe.

[0007] Preferably, the pressure conveying mechanism is a concrete conveying pump installed between the concrete distributor and the lifting mechanism, and the concrete conveying pump is any one of a piston concrete pump, a screw pump, and an extrusion pump.

[0008] More preferably, the concrete distributor has at least one or more first sealed housings for holding concrete connected by a shut-off valve B. The pressure delivery mechanism includes a control unit, an air compressor, an air tank for storing pressurized air, and a high-pressure air pipe with a shut-off valve A. The two ends of the high-pressure air pipe are respectively connected to the air tank and the first sealed housing. A pressure relief valve A is provided on the first sealed housing. Both the shut-off valve A and the pressure relief valve A are electrically connected to the control unit.

[0009] This invention also provides a casting process for continuous casting of an anti-seepage wall, which is implemented using the intelligent adaptive casting system described above, and specifically includes the following steps: Step STP100, System Installation and Initialization: Vertically install the liquid level sensor at the inlet of the trench inside the anti-seepage wall trench, and set the maximum detection value of the liquid level sensor at the inlet of the trench. Align with the mud surface, minimum detection value With the maximum detection value The distance between them shall not be less than 20cm; the lifting mechanism shall be installed between two adjacent equally divided pouring sections, and the distance between the lower end face of the pouring pipe held by the lifting mechanism and the bottom of the anti-seepage wall trench shall be... Initialize the system; Step STP200: Closed-loop control adaptive pouring. The concrete supply mechanism continuously or intermittently supplies a predetermined mix of concrete to the concrete distributor. At least one pressure conveying mechanism pressurizes and delivers the concrete to the corresponding connected pouring pipe for pouring. The mud recovery controller controls the mud recovery pump to pump the mud into the mud storage tank based on the mud level data sent by the mud level sensor at the tank opening and records the flow rate of the recovered mud. This ensures that the mud is always at the minimum detection value. With the maximum detection value Between; the control center recovers mud flow Average cross-sectional area of ​​the anti-seepage wall trench Obtain casting pipe t The burial depth of the pouring pipe : in, yes t Concrete thickness at any given time, in meters (m). yes t Total amount of mud recovered at any given time, in cubic meters (m³) 3 , It is the average cross-sectional area of ​​the anti-seepage wall trench, in meters. 2 ; It is the initial distance between the lower end face of the pouring pipe and the bottom of the anti-seepage wall trench, in meters; , These represent the preset maximum and minimum burial depths, respectively, in meters (m). Until the concrete poured for the seepage barrier wall reaches 20cm below the suction inlet of the mud recovery pump; Step STP300: Fully pour the concrete into the trench. Visually inspect the work to remove all the mud from the trench and pour the concrete to the target height in one go.

[0010] Preferably, in step STP200, when the concrete pressurized conveying method is uninterrupted continuous conveying, the pressure conveying mechanism is a concrete conveying pump, and the number of concrete conveying pumps is n, which are installed as a set with the pouring pipe and the lifting mechanism.

[0011] More preferably, in step STP200, when the concrete pressurization and conveying method is uninterrupted continuous conveying, the pressure conveying mechanism is a compressed air supply unit. The compressed air supply unit includes an air compressor, an air tank, and a high-pressure air pipe connected in sequence. A shut-off valve A is provided on the high-pressure air pipe. The concrete distributor includes a first sealed housing and a second sealed housing, as well as shut-off valves C and B, respectively located near the top and bottom of the first sealed housing for connecting the first sealed housing and the second sealed housing. Concrete supply process: Close shut-off valves B and C, open the pressure relief valve B on the second sealed housing of the concrete distributor to discharge the high-pressure gas in the second sealed housing, open the second sealed housing to receive the concrete introduced from the concrete supply mechanism, after receiving, close the second sealed housing and pressure relief valve B, and then open shut-off valve C and shut-off valve B in sequence to equalize the pressure; repeat the concrete supply process multiple times. Concrete pouring process: Close the sealed shell and pressure relief valve A, open the shut-off valve A to allow ventilation, and then open the pouring pipe valve group to perform adaptive concrete pouring.

[0012] More preferably, in step STP200, when the concrete pressurization and conveying method is intermittent conveying, the pressure conveying mechanism is a compressed air supply unit. The compressed air supply unit includes an air compressor, an air storage tank, and a high-pressure air pipe connected in sequence. A shut-off valve A is installed on the high-pressure air pipe. The concrete supply process is as follows: close the pouring pipe valve group and shut-off valve A, open the pressure relief valve A to discharge the high-pressure gas in the first sealed housing of the concrete distributor, and then open the first sealed housing to receive the concrete introduced from the concrete supply mechanism. The concrete pouring process is as follows: close the first sealed housing and pressure relief valve A, open the shut-off valve A to allow air to pass through, and then open the pouring pipe valve group to perform adaptive concrete pouring.

[0013] Beneficial effects: 1. This invention employs a pressurized supply system based on a concrete delivery pump or a sealed pressurized tank. Compared to the existing method of relying on the self-weight of concrete for pouring, it achieves the technical effect of applying continuous and stable additional pressure to the concrete in the pouring pipe. This pressure can effectively overcome the greater resistance of concrete flow in the guide tube and the slot, thereby allowing the bottom of the pouring pipe to maintain a larger safe burial depth range in the concrete. It significantly reduces the stringent requirements for the timing and height control of pipe pulling, and the system has stronger fault tolerance, fundamentally avoiding the risk of "cast pipe" caused by excessive instantaneous burial depth.

[0014] 2. This invention adopts a technical solution of setting a fast-response shut-off valve at the top of each pouring pipe. Compared with the existing technology that requires interrupting the concrete supply when lifting the guide pipe, this invention achieves the technical effect of instantly cutting off the concrete fluid in a single pipe before disassembling the pipe section. This ensures that the pouring pipe system is completely isolated from the slurry environment in the trench during the lifting and disassembly of the pipe section, completely eliminating the risk of slurry backflow into the pipe and concrete leakage, and ensuring the purity and integrity of the concrete wall.

[0015] 3. This invention employs a closed-loop control system based on a liquid level sensor at the trench opening to monitor and calculate the concrete rise height and the theoretical burial depth of the pouring pipe in real time. Compared with the existing technology that relies on intermittent and delayed manual measurement, this invention achieves the technical effect of continuous, accurate, and real-time perception of the concrete filling status in the trench. It provides accurate data for the decision-making on lifting the pouring pipe, realizes the automation and intelligence of the timing of lifting, and completely eliminates the quality risks caused by human measurement errors and judgment delays.

[0016] 4. This invention employs a closed-loop control subsystem that integrates mud level monitoring and automatic recycling. Compared to existing technologies that rely on mud overflow or manual operation, this invention achieves the technical effect of automatically maintaining the mud level in the tank within a preset safe range during the pouring process. On the one hand, it realizes the automatic recycling and reuse of mud resources, avoiding waste and environmental pollution. On the other hand, the stable mud level provides a reliable benchmark for calculating the concrete rise height and prevents the risk of hole collapse caused by excessively high or low mud levels in the tank walls.

[0017] 5. This invention integrates the pressurization supply system, valve control system, lifting execution system, and liquid level monitoring system into a unified intelligent closed-loop control system. Compared with the existing technology where each process is relatively independent and relies on manual coordination, this invention achieves the technical effect of fully automatic, high-precision, and coordinated operation of the entire anti-seepage wall pouring process. It significantly reduces the dependence on the experience of operators, and significantly improves construction efficiency, quality consistency, and project safety. It represents the transformation of anti-seepage wall construction from traditional techniques to modern intelligent construction. Attached Figure Description

[0030] Example 1: This embodiment provides an intelligent adaptive pouring system; see the appendix of the instruction manual. Figure 1 As shown, the adaptive casting system provided in this embodiment is used for adaptive casting of anti-seepage walls, including... A concrete pressure delivery system includes a concrete supply mechanism, a concrete distributor, a pressure delivery mechanism, and a distribution valve control mechanism. The pressure delivery mechanism pressurizes the concrete in the concrete distributor and then injects it into the seepage-proof wall trench through the distribution valve control mechanism. The distribution valve control mechanism includes n pouring pipe valve groups, where n ≥ 1; see also Figure 1 As shown, this embodiment provides a system structure with three pouring pipe valve groups. After the system is started, the concrete pressure conveying system starts to work. The concrete supply mechanism conveys the prepared concrete to the concrete distributor. The concrete is pressurized by the pressure conveying mechanism and then injected into the bottom of the anti-seepage wall trench through the pouring pipe 4.

[0031] The liquid level monitoring and mud recovery system includes a tank opening liquid level sensor installed near the opening of the cutoff wall trench to detect the real-time mud level, and a mud recovery controller to receive data from the tank opening liquid level sensor and control the mud recovery pump to pump the mud from the cutoff wall trench into a mud storage tank. During the construction of the cutoff wall, as concrete is continuously poured in, the space in the cutoff wall trench is occupied by concrete, and the mud level will continuously rise. Therefore, the liquid level monitoring and mud recovery system operates synchronously while concrete is continuously poured into the cutoff wall trench. The tank opening liquid level sensor monitors the liquid level height at the top of the cutoff wall trench in real time. The data is then transmitted to the mud recovery controller and control center, and when the liquid level reaches a certain height... Reaching the preset maximum detection value At that time, the mud recovery pump starts working; when the liquid level reaches a certain height... Reaching the preset minimum detection value When the mud level reaches a certain point, the mud recovery pump stops working; this ensures that the real-time mud level is maintained throughout the entire pouring process. Always at the minimum detection value With the maximum detection value between.

[0032] The intelligent pipe-pulling system includes a control center and a lifting execution system. The control center calculates the current burial depth of the casting pipe 4 by receiving real-time data from the liquid level sensor and the mud recovery controller. The system sends lifting control commands to the lifting execution reminder. The lifting execution system includes multiple lifting mechanisms 3 for lifting the pouring pipe 4. The control center recovers the mud flow rate. Average cross-sectional area of ​​the anti-seepage wall trench Obtain 4 casting pipes t Burial depth of the pouring pipe 4 : in, yes t Concrete thickness at any given time, in meters (m). yes t Total amount of mud recovered at any given time, in cubic meters (m³) 3 , It is the average cross-sectional area of ​​the anti-seepage wall trench, in meters. 2 ; It is the initial distance between the lower end face of the casting pipe 4 and the bottom of the anti-seepage wall trench, in meters; , These represent the preset maximum and minimum burial depths, in meters; once the concrete has been poured to the top of the anti-seepage wall trench, the final pouring can be completed visually.

[0033] Example 2: This embodiment, based on Embodiment 1, provides a continuous boosting scheme to further optimize the boosting method. For details, please refer to the appendix of the instruction manual. Figure 2As shown, the pressure conveying mechanism is a concrete conveying pump 2 installed between the concrete distributor and the lifting mechanism 3. The concrete conveying pump 2 is any one of a piston concrete pump, a screw pump, and an extrusion pump. Using a concrete pump 2 allows for independent pouring and lifting of multiple pouring pipes 4. During pressurized pouring, the slurry level rises adaptively as concrete is continuously injected, and is intelligently recovered via a slurry recovery controller. Therefore, in this embodiment, slurry recovery is not a concern during concrete pouring. When pipe removal is required, each pouring pipe 4 is equipped with a valve group to control its on / off state. Therefore, when lifting a pouring pipe 4, closing the corresponding valve group and the concrete pump 2 stops the continued supply of concrete, making lifting the pipe 4 much easier. The time required to remove the top section of the pouring pipe 4 is significantly less than the time it takes for the internal concrete to fall, effectively preventing air from entering the pouring pipe 4. This solves the problem of concrete leakage and air ingress caused by existing pipe removal methods, further improving the pouring quality of the anti-seepage wall.

[0034] Example 3: This embodiment further optimizes Embodiment 1, providing a technical solution for pressurizing and conveying concrete using a pressure conveying mechanism that differs from Embodiment 2. For details, please refer to the appendix to the specification. Figures 3-4 As shown, the concrete distributor has at least one or more first sealed housings 1 for holding concrete, connected via shut-off valve B13. The pressure delivery mechanism includes a control unit, an air compressor 9, an air tank 8 for storing pressurized air, and a high-pressure air pipe with shut-off valve A7. The two ends of the high-pressure air pipe are connected to the air tank 8 and the first sealed housing 1, respectively. A pressure relief valve A6 is provided on the first sealed housing 1. Both the shut-off valve A7 and the pressure relief valve A6 are electrically connected to the control unit. This embodiment is illustrated using a single first sealed housing 1 as an example; see [link to documentation]. Figure 3 As shown, the concrete is temporarily stored in the first sealed shell 1. The principle will be briefly described below according to the sequence of the workflow: Step 1: Concrete supply. The concrete is supplied by a concrete supply organization, such as an existing concrete mixing plant, where the mixer truck supplies the concrete to the first sealed shell 1. When receiving concrete, the top cover or inlet of the first sealed shell 1 is open to receive the concrete. Of course, it can also be set as a quick-connect flange structure, which depends on the supply method of the concrete supply organization. This is an adaptive improvement in the existing technology, and there are many implementation schemes, which will not be listed here. As long as the concrete receiving and sealing can be met, it is acceptable.

[0035] The second step is the delivery and pouring of concrete. After the concrete enters the first sealed shell 1, it needs to be pressurized and delivered to the anti-seepage wall trench 5. This is a solution that significantly differs from the existing gravity pouring method, which has high requirements for the timing and height of pipe extraction. Because pressure delivery is used, even if the burial depth of the pouring pipe 4 exceeds the optimal depth of 2-6m specified in the existing standards, the concrete supply can continue without being affected. With the intelligent recovery of mud by the mud recovery controller at the top of the anti-seepage wall trench 5, the error tolerance of pipe extraction timing and height can be greatly improved. Moreover, the technical solution of this embodiment is almost unaffected by the construction depth. The air compressor 9 serves as the source of compressed air, and the air storage tank 8 is a device for storing compressed air, enabling a continuous and stable delivery of high-pressure air. The shut-off valve A7 connects or disconnects the high-pressure air source in the air storage tank 8 from the first sealed shell 1 as needed in real time, so as to switch between receiving concrete and concrete delivery modes. It is worth noting that the volume of the first sealed shell 1 is usually very large, and a single full filling can meet the needs of long-term construction. It can also be customized according to different construction projects. Under the action of compressed air, concrete can be quickly pressed into the anti-seepage wall trench 5 through the pouring pipe 4. When secondary receiving and replenishment of concrete are required, the high-pressure air in the first sealed shell 1 needs to be discharged by opening the pressure relief valve A6 first, and then the first sealed shell 1 can be opened or the concrete receiving port of the first sealed shell 1 can be connected to the concrete supply mechanism to replenish the concrete. This cycle can be repeated to achieve intermittent and efficient supply.

[0036] Example 4: This embodiment provides a casting process for continuous casting of an anti-seepage wall, which is implemented using the intelligent adaptive casting system described above, and specifically includes the following steps: Step STP100, System Installation and Initialization: Vertically install the liquid level sensor at the inlet of the trench inside the anti-seepage wall trench, and set the maximum detection value of the liquid level sensor at the inlet of the trench. Align with the mud surface, minimum detection value With the maximum detection value The distance between them shall not be less than 20cm; the lifting mechanism 3 shall be installed between two adjacent equally divided pouring sections, and the distance between the lower end face of the pouring pipe 4 held by the lifting mechanism 3 and the bottom of the anti-seepage wall trench shall be... Initialize the system; Step STP200: Closed-loop control adaptive pouring. The concrete supply mechanism continuously or intermittently supplies a predetermined mix of concrete to the concrete distributor. At least one pressure conveying mechanism pressurizes and delivers the concrete to the corresponding connected pouring pipe 4 for pouring. The mud recovery controller controls the mud recovery pump to pump the mud into the mud storage tank based on the mud level data sent by the tank level sensor and records the recovered mud flow rate. This ensures that the mud is always at the minimum detection value. With the maximum detection value Between; the control center recovers mud flow Average cross-sectional area of ​​the anti-seepage wall trench Obtain 4 casting pipes t Burial depth of the pouring pipe 4 : in, yes t Concrete thickness at any given time, in meters (m). yes t Total amount of mud recovered at any given time, in cubic meters (m³) 3 , It is the average cross-sectional area of ​​the anti-seepage wall trench, in meters. 2 ; It is the initial distance between the lower end face of the casting pipe 4 and the bottom of the anti-seepage wall trench, in meters; , These represent the preset maximum and minimum burial depths, respectively, in meters (m). Until the concrete poured for the seepage barrier wall reaches 20cm below the suction inlet of the mud recovery pump; Step STP300: Fully pour the concrete into the trench. Visually inspect the work to remove all the mud from the trench and pour the concrete to the target height in one go.

[0037] Using the total amount of recycled concrete The greatest advantage of this calculation method is that it provides actual feedback on the basic position of the rising concrete, meaning it's based on actual results. This is reliable and avoids the instability and uncertainty associated with using complex sensor systems in deep-seated operations. However, since the mud recovery system and concrete pouring are synchronized, using the cumulative increase in mud level to indicate the rise in concrete level would lead to data distortion. For example, when the mud recovery flow rate is the same as the concrete supply flow rate, the mud level will not change, but the actual concrete interface will be rising, leading to misjudgments of the pipe-pulling timing. The cumulative recovery amount used in this embodiment... This technical problem can be effectively solved through calculation. This is because the mud level is constantly being adjusted. Always at the minimum detection value With the maximum detection value Between, that is, the real-time mud level height The fluctuation range of the slurry is always at the centimeter level; while the burial depth of the casting pipe 4 is at the meter level, a difference of an order of magnitude. In other words, using the solution provided in this embodiment, regardless of the real-time mud level... The location of the pipe will not affect the judgment of the timing of pipe removal. For example, if the preset pipe removal depth is 10 meters, even if the real-time mud level is high... If the error reaches 0.5m, the burial depth control will still be between 9.5m and 10.5m, which will not affect the pipe pulling of the pressure delivery method used in this embodiment at all. Even if the burial depth reaches 12m or even 15m, the pressure delivery method used in this embodiment can still operate reliably, thereby greatly improving the redundancy of pipe pulling.

[0038] In this embodiment, as one of the optional pressurized conveying methods, when the concrete pressurized conveying method in step STP200 is uninterrupted continuous conveying, the pressure conveying mechanism is a concrete conveying pump 2, and the number of concrete conveying pumps 2 is n=3. Of course, when the anti-seepage wall pouring efficiency requirement is high, or the anti-seepage wall size is large, more numbers can be used, such as 4, 5, 6, or even 10. Those skilled in the art can arrange more concrete conveying pumps 2 based on the inventive concept provided in this embodiment and the actual project layout, and install them as a set with the pouring pipe 4 and the lifting mechanism 3.

[0039] In this embodiment, as one of the optional pressurized delivery methods, when the concrete pressurized delivery method in step STP200 is uninterrupted continuous delivery, the pressure delivery mechanism is a compressed air supply unit. The compressed air supply unit includes an air compressor 9, an air tank 8, and a high-pressure air pipe connected in sequence. A shut-off valve A7 is provided on the high-pressure air pipe. The concrete distributor includes a first sealed housing 1 and a second sealed housing 10, as well as shut-off valves C12 and B13 respectively located near the top and bottom of the first sealed housing 1 for connecting the first sealed housing 1 and the second sealed housing 10. Concrete supply process: Close shut-off valves B13 and C12, open the pressure relief valve B11 on the second sealed housing 10 of the concrete distributor to release the high-pressure gas inside the second sealed housing 10, open the second sealed housing 10 to receive the concrete introduced from the concrete supply mechanism, after receiving, close the second sealed housing 10 and pressure relief valve B11, and then open shut-off valve C12 and shut-off valve B13 in sequence to equalize the pressure; repeat the concrete supply process multiple times. Concrete pouring process: Close the sealed shell and pressure relief valve A6, open the shut-off valve A7 to allow ventilation, and then open the pouring pipe valve group 4 to perform adaptive concrete pouring.

[0040] In this embodiment, as one of the optional pressurized delivery methods, in step STP200, when the concrete pressurized delivery method is intermittent delivery, the pressure delivery mechanism is a compressed air supply unit. The compressed air supply unit includes an air compressor 9, an air tank 8, and a high-pressure air pipe connected in sequence. A shut-off valve A7 is installed on the high-pressure air pipe. The concrete supply process is as follows: close the pouring pipe valve group and shut-off valve A7, open the pressure relief valve A6 to discharge the high-pressure gas in the first sealed housing 1 of the concrete distributor, and then open the first sealed housing 1 to receive the concrete introduced from the concrete supply mechanism. The concrete pouring process is as follows: close the first sealed housing 1 and pressure relief valve A6, open the shut-off valve A7 to allow air to pass through, and then open the pouring pipe valve group to perform adaptive concrete pouring.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
