Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] At present, the post-collapse filling technology of underground continuous wall trenches in the industry is mostly operated by on-site workers relying on observation and experience. The height of the liquid level of the poured concrete is determined by naked eye monitoring or simple measuring tools.

[0042] However, manual observation and operation are limited by human factors and there is a risk of misjudgment and untimely response, which makes it difficult to control the liquid level of the supplementary concrete after the underground continuous wall trench collapses, and over-pouring often occurs.

[0043] In order to solve this technical problem, the present invention proposes a device and method for preventing over-flooding after underground continuous wall trench collapse.

[0044] See also Figures 1 to 5In one embodiment of the present invention, an underground continuous wall trench wall is arranged in a trench section, and the underground continuous wall trench wall collapse prevention overfilling detection device comprises a mobile base 100, a support frame 200, a floating mechanism 300 and an overfilling prevention detection mechanism 400, wherein the support frame 200 is mounted on the mobile base 100; the floating mechanism 300 is slidably mounted on the support frame 200 in a vertical direction, and the floating mechanism 300 can move between an initial position extending into the trench section and a sensing position moving out of the trench section; the discharge port of the concrete pumping system 500 is arranged below the floating mechanism 300; the overfilling prevention detection mechanism 400 comprises a control module 410, a sensing module 420, and a control module 430. Module 420 and sensing element 430, the sensing module 420 is installed on the side of the support frame 200 facing the floating mechanism 300, the sensing element 430 is installed on the side of the floating mechanism 300 facing the sensing module 420 corresponding to the position of the sensing module 420, the sensing module 420 and the concrete pumping system 500 are both electrically connected to the control module 410; wherein the sensing module 420 is used to sense the sensing element 430 when the concrete in the groove section lifts the floating mechanism 300 from the initial position to the sensing position, and send a sensing signal to the control module 410; the control module 410 is used to stop the concrete pumping system 500 according to the sensing signal.

[0045] Specifically, the support frame 200 is mounted on the mobile base 100, providing good mobility and stability for the entire floating mechanism 300. The floating mechanism 300 is slidably mounted on the support frame 200 in the vertical direction, so that the floating mechanism 300 can move vertically inside and outside the trough section, providing a basis for realizing real-time monitoring of the concrete liquid level.

[0046] The floating mechanism 300 can move between an initial position extending into the tank section and a sensing position moving out of the tank section. The floating mechanism 300 can float up with the rise of the concrete liquid level in the tank section, thereby accurately reflecting the actual height of the concrete in the tank section. The discharge port of the concrete pumping system 500 is set below the floating mechanism 300 to ensure that the concrete can be accurately injected into the tank section without interfering with the floating process of the floating mechanism 300.

[0047] Furthermore, the sensing module 420 is installed on the side of the support frame 200 facing the floating mechanism 300, and the sensing member 430 is installed on the side of the floating mechanism 300 facing the sensing module 420 corresponding to the position of the sensing module 420. This ensures that the sensing module 420 can accurately sense the position of the sensing member 430 when the floating mechanism 300 rises to a preset height, thereby monitoring the liquid level of the concrete in the tank section. The sensing module 420 and the concrete pumping system 500 are both electrically connected to the control module 410 to form a closed-loop control system.

[0048] More specifically, when the concrete in the trench section lifts the floating mechanism 300 from the initial position to the sensing position, the sensing module 420 senses the presence of the sensing member 430 and sends a sensing signal to the control module 410. After receiving the sensing signal, the control module 410 immediately instructs the concrete pumping system 500 to stop working, thereby avoiding over-pouring of concrete. The automated control process greatly improves the accuracy and reliability of the refilling after the underground continuous wall trench collapses.

[0049] In the technical solution provided by the present invention, the synergistic effect of the mobile base 100, the support frame 200, the floating mechanism 300 and the anti-overfilling detection mechanism 400 effectively solves the operational limitation that the concrete liquid level is difficult to control when the underground continuous wall groove wall collapses. The mobile base 100 and the support frame 200 provide stability and maneuverability for the floating mechanism 300, and the floating mechanism 300 can float with the rise of the concrete liquid level, and monitor the actual height of the concrete liquid level in the groove section in real time. And the sensing module 420 and the sensing element 430 in the anti-overfilling detection mechanism 400 are used to convert the floating process of the floating mechanism 300 into a sensing signal, and the control module 410 controls the concrete pumping system 500 to stop working according to the sensing signal. Not only the operational accuracy and reliability of the refilling process after the underground continuous wall groove wall collapse are significantly improved, but also the risk of human misjudgment and reaction delay is reduced, thereby ensuring the quality and efficiency of the refilling concrete after the underground continuous wall groove wall collapses.

[0050] As an optional implementation of this embodiment, the floating mechanism 300 can adopt a hollow structure to reduce weight and improve buoyancy. The sensing module 420 can adopt a photoelectric sensor or a magnetic sensor in the prior art to improve the accuracy and response speed of the sensing. The control module 410 can adopt a programmable logic controller (PLC) in the prior art to achieve more complex control logic and data recording functions.

[0051] In an embodiment of the present invention, the floating mechanism 300 includes a floating plate 310 and a plurality of guide rods 320, wherein the plurality of guide rods 320 are installed at the top of the floating plate 310 at intervals along the circumference of the floating plate 310, each guide rod 320 extends vertically, and each guide rod 320 is slidably connected to the support frame 200, the floating plate 310 is arranged below the support frame 200, and the sensing element 430 is installed on a side of the floating plate 310 facing the sensing module 420 corresponding to the position of the sensing module 420; the discharge port of the concrete pumping system 500 is arranged below the floating plate 310; wherein the sensing module 420 is used to sense the sensing element 430 when the concrete in the slot section lifts the floating plate 310 from the initial position to the sensing position, and send a sensing signal to the control module 410.

[0052] Please continue reading Figure 3 and Figure 4In an embodiment of the present invention, the support frame 200 includes a top plate 210 and a plurality of hollow limit columns 220. The plurality of hollow limit columns 220 are installed at the bottom of the top plate 210 at circumferential intervals along the top plate 210. The number of the hollow limit columns 220 is consistent with the number of the guide rods 320 and is arranged one by one. Each guide rod 320 is slidably installed in the corresponding hollow limit column 220 along the vertical direction.

[0053] Specifically, the top plate 210, as the main body of the support frame 200, provides a solid installation foundation for the plurality of hollow limiting columns 220. The plurality of hollow limiting columns 220 are installed at intervals along the circumference of the top plate 210, which not only enhances the stability of the overall structure, but also provides evenly distributed guide channels for the guide rods 320.

[0054] The one-to-one correspondence between the hollow limit column 220 and the guide rod 320 ensures that each guide rod 320 has a dedicated guide channel. This effectively prevents the guide rod 320 from being offset or disturbed during movement, thereby ensuring the smooth movement of the floating mechanism 300 and improving the accuracy and reliability of the floating mechanism 300 in monitoring the concrete liquid level in the slot section. The guide rod 320 can slide freely vertically in the corresponding hollow limit column 220, so that the floating mechanism 300 can accurately float up following the changes in the concrete liquid level. At the same time, this structure is also easy to maintain and replace, improving the practicality and service life of the device.

[0055] More specifically, the floating mechanism 300 is connected to the support frame 200 through the guide rod 320, and can move between the initial position in the slot section and the sensing position outside the slot section. This structure of the support frame 200 ensures that the floating mechanism 300 remains stable and accurate throughout the movement process. When the concrete liquid level rises, the floating mechanism 300 can float up smoothly until it reaches the sensing position and is sensed by the overfilling prevention detection mechanism 400.

[0056] As an optional implementation of this embodiment, the hollow limit column 220 can be made of high-strength alloy material to improve its wear resistance and service life. The surface of the guide rod 320 can be specially treated, such as chrome plating or coating with a material with a low friction coefficient, to reduce friction between the hollow limit column 220 and improve the smoothness of movement.

[0057] In the embodiment of the present invention, the top end of each hollow limiting column 220 extends out from the top of the top plate 210 , and a limiting plate 321 is installed on the top of each guide rod 320 .

[0058] Specifically, the main function of the limit plate 321 is to prevent the guide rod 320 from completely disengaging from the hollow limit column 220, and to ensure that the floating mechanism 300 is always connected to the support frame 200. This effectively prevents the floating mechanism 300 from being separated or out of control during the descent process, greatly improving the safety and reliability of the device.

[0059] In an embodiment of the present invention, the concrete pumping system 500 includes a concrete pump and a pumping pipe. The concrete pump is electrically connected to the control module 410. The feed port of the pumping pipe is connected to the concrete pump. The floating plate 310 is formed with a through hole 311 for plugging the pumping pipe. The through hole 311 extends vertically, and the discharge port of the pumping pipe is connected to the through hole 311.

[0060] It should be noted that the concrete pumping system 500 is a prior art.

[0061] Specifically, the through opening 311 formed on the floating plate 310 extends vertically, providing a movable passage for the pumping pipe, so that the pumping pipe can maintain a relatively fixed position when the floating mechanism 300 moves up and down, ensuring that concrete can be continuously transported to the trough section without interruption even when the floating mechanism 300 is rising, greatly reducing the problems such as pipe twisting or blockage during concrete transportation.

[0062] Please continue reading Figures 1 to 4 In an embodiment of the present invention, an opening 211 for the pumping pipe to pass through is provided at the top center of the top plate 210, and a groove 212 for placing the pumping pipe is formed in a recessed manner at the top periphery of the top plate 210, and the discharge port of the pumping pipe extends downward from the groove 212 through the opening 211 into the through-port 311.

[0063] Specifically, the opening 211 at the top center of the top plate 210 provides a passage for the pumping pipe to pass through the top plate 210, so that the pumping pipe can be directly connected to the through-hole 311 of the floating mechanism 300 from above the support frame 200. This ensures that the path of the pumping pipe is the shortest and most direct, reducing the resistance and bending encountered by the concrete during the transportation process.

[0064] The groove 212 formed by the top edge of the top plate 210 provides a stable placement for the pump pipe, effectively preventing the pump pipe from lateral movement or excessive vibration during operation. The groove 212 can also help operators to more easily locate and install the pump pipe, thereby improving the operability of the device.

[0065] The discharge port of the pump pipe extends downward from the groove 212 through the opening 211 into the through opening 311, forming a continuous concrete delivery channel, which not only ensures the continuity and stability of concrete delivery, but also enables the pump pipe to slide freely with the up and down movement of the floating mechanism 300, avoiding damage to the pump pipe caused by the movement of the floating mechanism 300.

[0066] More specifically, the floating mechanism 300 can move between an initial position in the slot section and a sensing position outside the slot section, and the continuous passage formed by the pumping pipe through the opening 211 of the top plate 210 and the through-hole 311 of the floating plate 310 ensures that the concrete delivery will not be disturbed during the whole process, thereby improving the accuracy and controllability of concrete pouring.

[0067] As an optional embodiment, the top plate 210 is made of wear-resistant material, such as high-density polyethylene, to extend the service life of the groove 212 integrally formed therewith. The bottom of the groove 212 is a slightly inclined structure to facilitate the discharge of moisture or impurities accumulated on rainy days during construction.

[0068] Please continue reading Figure 1 and Figure 4 In an embodiment of the present invention, there are two mobile bases 100, and the two mobile bases 100 are arranged on opposite sides of the top of the trough section; each mobile base 100 includes a pulley 110 and a connecting frame 120, the bottom end of the connecting frame 120 is installed on the pulley 110, and the top end of the connecting frame 120 is connected to the support frame 200 and is used to suspend the support frame 200 on the top of the trough section.

[0069] It should be noted that the pulley 110 is a prior art.

[0070] Specifically, there are two mobile bases 100, which are arranged on opposite sides of the top of the trough section, ensuring that the entire device can move smoothly on the road surface outside the top of the trough section. This not only enhances the supporting force of the overall structure, but also improves the adaptability of the device, and can adapt to trough sections of different widths.

[0071] The pulley 110, as the bottom structure of the mobile base 100, provides good mobility. The entire device can be easily moved along the extension direction of the slot section, which is convenient for adjusting the position and performing inspection work in different areas. In addition, the bottom end of the connecting frame 120 is installed on the pulley 110, forming a stable basic structure.

[0072] The top of the connecting frame 120 is connected to the supporting frame 200 and is used to suspend the supporting frame 200 on the top of the trough section. The cantilever installation of the supporting frame 200 is realized, so that the entire detection device can be suspended above the trough section without interfering with the construction work or structure in the trough section. Suspending the supporting frame 200 on the top of the trough section through the connecting frame 120 not only ensures the stability of the detection device, but also improves its flexibility, so that the height and position of the device can be easily adjusted as needed.

[0073] In the embodiment of the present invention, a slide groove 111 is formed on the top of the pulley 110 , and the bottom end of the connecting frame 120 is slidably installed in the slide groove 111 along the horizontal direction, and the top end of the connecting frame 120 is hinged to the support frame 200 .

[0074] Specifically, the slide groove 111 provides a horizontal moving channel for the bottom end of the connecting frame 120, and the horizontal direction is perpendicular to the extension direction of the slot segment. The connecting frame 120 can slide freely in the horizontal direction in the slide groove 111, thereby realizing the position adjustment capability of the device in the horizontal direction to adapt to slot segments of different sizes.

[0075] The bottom end of the connecting frame 120 can be slidably mounted in the slide slot 111, which not only increases the flexibility of the entire structure, but also improves the stability of the device. This sliding connection method allows the connecting frame 120 to be able to perform a small range of horizontal adjustment as needed while maintaining stable support. This is helpful for dealing with irregular shapes of slot sections or situations that require precise positioning.

[0076] The top of the connecting frame 120 is hinged to the supporting frame 200, so that the supporting frame 200 can rotate at a certain angle relative to the connecting frame 120. This is conducive to adapting to different construction environments and detection requirements. For example, when the surface of the groove section is uneven or the detection angle needs to be adjusted, the operator can easily adjust the angle of the supporting frame 200 through this hinge structure without moving the entire device.

[0077] This embodiment not only improves the accuracy and adaptability of the device, but also enhances its operational convenience. The operator can achieve horizontal fine-tuning through the slide slot 111 and vertical angle adjustment through the hinge, thereby quickly and accurately positioning the detection device to the optimal position. This multi-dimensional adjustment capability improves the accuracy and efficiency of detection.

[0078] Please continue to refer to Figure 1 and Figure 4 In an embodiment of the present invention, the mobile base 100 also includes a driving member 130, which is installed on the pulley 110. The output end of the driving member 130 is connected to the bottom end of the connecting frame 120 and is used to drive the bottom end of the connecting frame 120 to slide in the slide groove 111 along the horizontal direction.

[0079] Specifically, the driver 130 automates the level adjustment process that originally required manual operation, thereby improving the accuracy and efficiency of the device adjustment. The driver 130 is installed on the pulley 110, ensuring that the driver 130 and the pulley 110 form a stable whole, reducing vibration and error during movement.

[0080] The output end of the driver 130 is connected to the bottom end of the connecting frame 120, so that the driver 130 can directly control the horizontal movement of the connecting frame 120 in the slide slot 111. By accurately controlling the output of the driver 130, the operator can achieve fine adjustment of the position of the connecting frame 120, thereby improving the precise positioning capability of the device.

[0081] As an optional embodiment, the drive member 130 may adopt a stepper motor in the prior art to achieve higher precision position control. The drive member 130 may be equipped with an encoder for accurately monitoring the position of the connecting frame 120. In addition, a position feedback mechanism may be added to the control system of the drive member 130, so that the entire adjustment process forms a closed-loop control system, further improving the positioning accuracy.

[0082] Please continue reading Figures 1 to 5 , and see Figure 6 The present invention also proposes a method for detecting overfilling after underground continuous wall trench wall collapse, using the above-mentioned device for detecting overfilling after underground continuous wall trench wall collapse. The method for detecting overfilling after underground continuous wall trench wall collapse comprises:

[0083] Step S10, moving the mobile base 100 to the trench section after the underground continuous wall trench wall collapses and fixing it;

[0084] Step S20, adjusting the floating mechanism 300 to the initial position so that the floating mechanism 300 extends into the slot section;

[0085] Step S30, controlling the concrete pumping system 500 to transport concrete into the trough section;

[0086] Step S40, when the liquid level of concrete in the trough section rises, the sensing element 430 on the floating mechanism 300 moves from the initial position to the sensing position along with the floating mechanism 300, so that the sensing module 420 senses the sensing element 430 to generate the sensing signal, and sends the sensing signal to the control module 410;

[0087] Step S50: After receiving the sensing signal, the control module 410 controls the concrete pumping system 500 to stop pumping concrete to prevent over-filling.

[0088] Specifically, step S10 ensures that the detection device can be accurately positioned at the slot section that needs to be refilled. By fixing the mobile base 100, a stable foundation is provided for the entire detection process, which helps to improve the accuracy of subsequent operations.

[0089] Step S20 adjusts the floating mechanism 300 to the initial position so that it extends into the groove section. Prepare for the detection process and ensure that the floating mechanism 300 can track the rise of the concrete liquid level from the lowest point. By accurately positioning the initial position of the floating mechanism 300, the changes in the concrete liquid level during the entire refilling process can be accurately captured.

[0090] Step S30 controls the concrete pumping system 500 to deliver concrete to the tank section. The actual refilling process begins. By controlling the concrete pumping system 500, it can be ensured that the concrete is delivered to the tank section at an appropriate rate and amount.

[0091] In step S40, when the concrete liquid level in the tank section rises, the sensing element 430 on the floating mechanism 300 moves from the initial position to the sensing position along with the floating mechanism 300. As the concrete liquid level rises, the floating mechanism 300 is gradually raised until the sensing element 430 reaches the sensing range of the sensing module 420, so that the sensing module 420 generates a sensing signal and sends the sensing signal to the control module 410.

[0092] In step S50, after receiving the sensing signal, the control module 410 controls the concrete pumping system 500 to stop concrete pumping to prevent overfilling. Automatic control is implemented to ensure that the replenishment is stopped in time when the concrete reaches a predetermined height, effectively preventing the occurrence of overfilling.
