Description

Technical Field

[0001] This invention belongs to the field of soft soil treatment technology, specifically a stacked water bag height control system for soft soil treatment. Background Technology

[0002] The water bag height control system is a key technology for achieving precise load control in soft soil foundation treatment. Its core value lies in: improving engineering efficiency (mechanized water injection is more than 40% more efficient than traditional soil filling and surcharge, especially suitable for land-deficient areas and near-shore projects, and modular water bag cluster control technology supports large-scale rapid construction and shortens the preloading cycle by 50%), reducing overall costs (water sources are taken from nearby sources, and the water is treated and returned to the natural water system after unloading, reducing the cost of earthwork transportation and disposal), and ensuring safety and environmental protection (closed-loop water circulation design reduces resource consumption and avoids the damage to the surrounding water and soil environment caused by traditional surcharge).

[0003] In soft soil foundation treatment for infrastructure projects, the combined surcharge preloading process using water-filled bags as a load is widely applied. However, in actual engineering projects, insufficient water pressure and depressurization of the water-filled bags frequently occur, seriously affecting the treatment effect and project progress. Insufficient water pressure prevents the preloading load on the soft soil from meeting design requirements, thus failing to effectively promote soil consolidation. Depressurization can cause instability in the height of the water-filled bags, making it difficult for the entire surcharge preloading process to proceed as expected. Although existing technologies have conducted some research on water-filled bag surcharge processes, there is a lack of effective solutions for real-time and precise control of the water-filled bag height to address the problems of insufficient water pressure and depressurization.

[0004] Therefore, the present invention provides a stacked water bag height control system for soft soil treatment. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a stacked water bag height control system for soft soil treatment, comprising a pad layer, wherein an installation groove is provided on the top of the pad layer;

[0007] The installation groove is lined with multiple water bags, each with a vent at the top, and multiple pressure sensors are fixedly connected to the bottom of the installation groove.

[0008] The top of the padding layer is provided with a main groove, the inside of the main groove is provided with a main water pipe, multiple branch pipes are fixedly connected to the side of the main water pipe, and an inlet pipe is fixedly connected to the other side of the main water pipe.

[0009] An alarm is installed on the top of the pad, a solenoid valve is installed on the top of the branch pipe, a controller is fixedly connected to the top of the pad, and one end of the water inlet pipe passes through the pad and is fixedly connected to the outlet of the water pump.

[0010] Preferably, a pair of adjustment slots are provided on the top of the pad, and an electric push rod is fixedly connected inside the adjustment slot. The telescopic end of the electric push rod is fixedly connected to the bottom of the alarm.

[0011] Preferably, the top of the pad layer is provided with a pipe groove one and multiple pipe groove two, and the water inlet pipe and branch pipe are respectively arranged inside the pipe groove one and the pipe groove two.

[0012] Preferably, the bottom of the water bag is in contact with the top of the pressure sensor, and the top of the pad is flush with the top of the water bag.

[0013] Preferably, the pressure sensor, alarm, solenoid valve, water pump, and electric actuator are all electrically connected to the controller via wires.

[0014] Preferably, the top of the padding layer has multiple rectangular grooves, and rectangular blocks are inserted into the rectangular grooves. A connecting frame is fixedly connected to the top of the rectangular blocks. A reference plate is placed against the top of the water bag. A pair of sliders are fixedly connected to the top of the reference plate. A pair of sliding grooves that are slidably connected to the sliders are formed on the inner wall of the connecting frame. The top of the reference plate has multiple circular grooves, and reference blocks are movably inserted into the circular grooves. In the initial state, the bottom of the reference block abuts against the top of the water bag.

[0015] Preferably, the bottom of the rectangular block is fixedly connected with multiple reinforcing cones, which are initially inserted inside the padding layer.

[0016] Preferably, a limiting groove is formed on each of the two inner sidewalls of the slide groove, and a limiting block is fixedly connected to each of the two sidewalls of the slider and is slidably connected to the limiting groove.

[0017] Preferably, the top of the reference plate is provided with a docking groove, and the center of the docking groove and the center of the exhaust hole are on the same vertical line.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The present invention discloses a water bag height control system for soft soil foundation treatment. In use, the present invention monitors the water bag pressure and height in real time and makes intelligent adjustments based on preset parameters. This effectively solves the problems of insufficient water level caused by water leakage and pressure loss caused by water bag damage, thereby achieving precise control of the water level inside the water bag and ensuring the quality and efficiency of soft soil foundation treatment for infrastructure projects.

[0020] 2. The water bag height control system for soft soil treatment described in this invention requires the rectangular block to be inserted into the rectangular groove during use, so that the bottom of the reference plate abuts against the top of the water bag. When the water bag is damaged and its height decreases, the reference plate on it will move down with it. At this time, personnel only need to observe the position of the reference plate to quickly find the damaged water bag. When the water bag is damaged and the damaged area is concave, the reference block corresponding to the damaged area will move down. After finding the damaged water bag, the damaged area of ​​the water bag can be quickly found by simply looking at the position of the reference block. Therefore, this invention facilitates personnel to quickly find the damaged water bag and the damaged area on the water bag. Attached Figure Description

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1: As Figure 1-4As shown in the embodiment of the present invention, a stacked water bag height control system for soft soil treatment includes a pad 1, and an installation groove 2 is provided on the top of the pad 1;

[0032] The interior of the mounting groove 2 is lined with multiple water bags 3, the top of the water bags 3 is provided with an exhaust hole 4, and multiple pressure sensors 5 are fixedly connected to the bottom of the mounting groove 2.

[0033] The top of the padding layer 1 is provided with a main groove 6, the inside of the main groove 6 is provided with a main water pipe 7, a number of branch pipes 8 are fixedly connected to the side of the main water pipe 7, and a water inlet pipe 9 is fixedly connected to the other side of the main water pipe 7.

[0034] An alarm 10 is provided on the top of the pad 1, a solenoid valve 11 is provided on the top of the branch pipe 8, a controller 27 is fixedly connected to the top of the pad 1, and one end of the water inlet pipe 9 passes through the pad 1 and is fixedly connected to the outlet end of the water pump 12.

[0035] like Figure 3 As shown, a pair of adjustment slots are provided on the top of the pad 1. An electric push rod 15 is fixedly connected inside the adjustment slot. The telescopic end of the electric push rod 15 is fixedly connected to the bottom of the alarm 10. When in use, the electric push rod 15 can be activated to adjust the height of the alarm 10, making it easier for personnel to detect the sound and light signals emitted by the alarm 10 in a timely manner.

[0036] like Figure 1 As shown, the top of the pad 1 is provided with a pipe groove 13 and a plurality of pipe grooves 14, and the water inlet pipe 9 and the branch pipe 8 are respectively arranged inside the pipe groove 13 and the pipe groove 14.

[0037] like Figure 1 As shown, the bottom of the water bag 3 is in contact with the top of the pressure sensor 5, and the top of the pad 1 is flush with the top of the water bag 3.

[0038] like Figure 1 As shown, the pressure sensor 5, alarm 10, solenoid valve 11, water pump 12 and electric push rod 15 are all electrically connected to the controller 27 via wires.

[0039] In soft soil treatment for infrastructure projects, the combined surcharge preloading process using water-filled bags (3) is widely applied. However, in actual projects, insufficient water pressure and depressurization of the water-filled bags (3) occur frequently, seriously affecting the treatment effect and project progress. Insufficient water pressure results in the preloading load on the soft soil failing to meet design requirements, thus failing to effectively promote soil consolidation; depressurization may cause instability in the height of the water-filled bags (3), making it difficult for the entire surcharge preloading process to proceed as expected. While existing technologies have conducted research on the water bag 3 stacking process, they lack effective solutions for real-time and precise control of the water bag 3 height to address insufficient water pressure and depressurization issues. In soft soil treatment projects, existing technologies using water bags 3 as a combined stacking preloading process suffer from insufficient water pressure, primarily due to water loss within the water bag 3: firstly, water loss through natural evaporation, and secondly, water loss caused by punctures from sharp objects or localized damage from sun exposure. Existing technologies rely heavily on manual inspection and water replenishment to maintain the water level in the water bag 3, leading to frequent instances of insufficient water level and delayed inspection and handling. Therefore, these technologies are insufficient in providing real-time and precise control of the water bag 3 height to address the aforementioned insufficient water pressure and depressurization problems.

[0040] In use, a high-precision pressure sensor 5 is installed at the bottom of the water bag 3 to monitor the pressure value inside the water bag 3 in real time and transmit the pressure data to the controller 27. This allows for accurate detection of minute changes in pressure inside the water bag 3, with a measurement accuracy of ±0.1 kPa. Utilizing the relationship between liquid static pressure and depth (P = ρgh), the water level is calculated by measuring the pressure. Its features include high monitoring accuracy (0.5% to 1% FS). A water pipe pressure sensor is installed after the water valve in the water supply network to monitor for damage to the water supply pipe. That is, when there is no water supply and the water supply pipe pressure is lost, it provides pressure loss feedback.

[0041] The water level in the water bag 3 is adjusted by the branch pipe 8 controlled by the solenoid valve 11. The solenoid valve 11 has the advantages of small size, light weight, low price, fast action and high reliability, and good sealing. It adjusts the water level in the water bag 3 according to the instructions of the control module, thereby controlling the height of the water bag 3 and maintaining the pressure of the water bag 3. The water pump 12 is a variable frequency water pump, which can adjust the pumping or injection speed according to actual needs.

[0042] The controller receives data transmitted from the pressure monitoring module and compares the real-time pressure value with the preset pressure threshold. If the real-time pressure value is lower than the lower limit of the pressure threshold, the controller controls the water level adjustment module to start the water pump 12 to inject water into the water bag 3. When the real-time pressure value reaches the upper limit of the pressure threshold, the controller controls the water level adjustment module to close the solenoid valve 11 and stop the water injection. At the same time, the controller can also record and store pressure and height data and generate data reports for subsequent analysis and review.

[0043] When the real-time pressure or height value exceeds the preset emergency threshold range, the alarm 10 will issue an audible and visual alarm signal to remind staff to handle the abnormal situation in a timely manner.

[0044] When using this invention, after the water bag 3 is laid, the controller 27 is started to initialize the pressure monitoring module, height monitoring module, water level adjustment module, control module and alarm module. The preset pressure threshold, height threshold and emergency threshold are input. The pressure monitoring module monitors the pressure value inside the water bag 3 in real time, the height monitoring module monitors the height value of the water bag 3 in real time, and transmits the data to the controller 27 in real time.

[0045] The control module receives pressure and height data, compares the real-time pressure value with the preset pressure threshold, and compares the real-time height value with the preset height threshold to determine whether the real-time pressure and height values ​​are within the normal range.

[0046] If the real-time pressure value is lower than the lower limit of the pressure threshold or the real-time height value is lower than the lower limit of the height threshold, the control module sends a water injection command to the water level adjustment module to start the water pump 12 to inject water into the water bag 3 until the real-time pressure value and height value reach the normal range. If the real-time pressure value is higher than the upper limit of the pressure threshold or the real-time height value is higher than the upper limit of the height threshold, the controller 27 sends a water pumping command to the water level adjustment module to start the water pump 12 to pump out the water in the water bag 3 until the real-time pressure value and height value reach the normal range.

[0047] When the real-time pressure or height value exceeds the preset emergency threshold range, the controller 27 triggers the alarm 10 to issue an audible and visual alarm signal, and the staff takes emergency measures in a timely manner based on the alarm information;

[0048] The controller 27 continuously records pressure and height data and generates data reports periodically. By analyzing the data, it evaluates the height and pressure control effect of the water bag 3 and provides a reference for similar projects in the future.

[0049] In summary, when in use, this invention effectively solves the problems of insufficient water level caused by leakage and depressurization caused by damage to the water bag 3 by real-time monitoring of the pressure and height of the water bag 3 and intelligent adjustment based on preset parameters. This achieves precise control of the water level inside the water bag 3 and ensures the quality and efficiency of soft soil treatment in infrastructure projects.

[0050] Example 2: Figure 5-7As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the top of the pad 1 is provided with a plurality of rectangular grooves 16, a rectangular block 17 is inserted inside the rectangular grooves 16, a connecting frame 28 is fixedly connected to the top of the rectangular block 17, a reference plate 18 is placed against the top of the water bag 3, a pair of sliders 19 are fixedly connected to the top of the reference plate 18, a pair of sliding grooves 20 are provided on the inner wall of the connecting frame 28 and are slidably connected to the sliders 19, a plurality of circular grooves 21 are provided on the top of the reference plate 18, a reference block 22 is movably inserted inside the circular groove 21, and in the initial state, the bottom of the reference block 22 abuts against the top of the water bag 3.

[0051] When using this invention, the rectangular block 17 needs to be inserted into the rectangular groove 16 so that the bottom of the reference plate 18 is against the top of the water bag 3. When the water bag 3 is damaged and its height drops, the reference plate 18 on it will move down with it. At this time, the personnel only need to observe the position of the reference plate 18 to quickly find the damaged water bag 3.

[0052] When the water bag 3 is damaged and the damaged area is dented, the reference block 22 corresponding to the damaged area will move down. Once the damaged water bag 3 is found, the damaged area of ​​the water bag 3 can be quickly located by referring to the position of the reference block 22.

[0053] In summary, when in use, this invention facilitates the quick location of damaged water bags 3 and the damaged areas on the water bags 3.

[0054] like Figure 5 As shown, the bottom of the rectangular block 17 is fixedly connected with a plurality of reinforcing cones 23. In the initial state, the reinforcing cones 23 are inserted into the interior of the padding layer 1.

[0055] After the reinforcing cone 23 is inserted into the pad 1, it can improve the stability of the rectangular block 17 in the rectangular groove 16.

[0056] like Figure 7 As shown, a pair of inner sidewalls of the slide groove 20 are provided with a limiting groove 24, and a pair of sidewalls of the slider 19 are fixedly connected with a limiting block 25 that is slidably connected to the limiting groove 24.

[0057] When slider 19 moves, limit block 25 will follow it and move within limit groove 24. Limit block 25 can improve the stability of slider 19 when it moves.

[0058] like Figure 7 As shown, the top of the reference plate 18 is provided with a docking groove 26, which facilitates the exhaust hole 4 to exhaust air. The center of the docking groove 26 and the center of the exhaust hole 4 are on the same vertical line.

[0059] The side wall frame of the present invention can be assembled and connected from multiple sets of unit plates. In actual use, it can be flexibly assembled according to the area of ​​use on site, and can be flexibly disassembled and transported after use.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
