[0041] At present, the underground continuous wall slot wall collapse after irrigation technology in the industry is mostly for on-site personnel to rely on observation and experience for operation. Through naked eye monitoring or simple measurement tool auxiliary, the liquid level height of pouring concrete is determined.
[0042] However, the artificial observation and manual operation are limited by human factors, and there is a risk of judgment error and untimely reaction, which makes it difficult to control the liquid level of the underground continuous wall slot wall collapse after pouring concrete, and the overpouring situation often occurs.
[0043] In order to solve the technical problem, the present application provides a kind of underground continuous wall slot wall collapse after overpouring detection device and method.
[0044] Please refer to Figures 1 to 5In an embodiment of the present application, the underground continuous wall slot wall is arranged in the slot section, and the anti-over-pouring detection device after the underground continuous wall slot wall collapses comprises a moving base 100, a support frame 200, a floating mechanism 300 and an anti-over-pouring detection mechanism 400. The support frame 200 is installed on the moving base 100. The floating mechanism 300 is slidably installed on the support frame 200 in the vertical direction, and the floating mechanism 300 can move between an initial position extending into the slot section and a sensing position moving out of the slot section. The discharge port of a concrete pumping system 500 is arranged below the floating mechanism 300. The anti-over-pouring detection mechanism 400 comprises a control module 410, a sensing module 420 and a sensing piece 430. The sensing module 420 is installed on one side of the support frame 200 facing the floating mechanism 300. The sensing piece 430 is installed on one 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 electrically connected to the control module 410. The sensing module 420 is used to sense the sensing piece 430 when the concrete in the slot section lifts the floating mechanism 300 from the initial position to the sensing position, and sends 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 installed on the moving base 100 to provide good mobility and stability for the entire floating mechanism 300. The floating mechanism 300 is slidably installed on the support frame 200 in the vertical direction, so that the floating mechanism 300 can move vertically in and out of the slot section, providing a basis for real-time monitoring of the liquid level of the concrete.
[0046] The floating mechanism 300 can move between an initial position extending into the slot section and a sensing position moving out of the slot section. This allows the floating mechanism 300 to float with the rising of the concrete liquid level in the slot section, thereby accurately reflecting the actual height of the concrete in the slot section. The discharge port of the concrete pumping system 500 is arranged below the floating mechanism 300, ensuring that the concrete can be accurately injected into the slot section without interfering with the floating process of the floating mechanism 300.
[0047] Furthermore, the sensing module 420 is installed on one side of the support frame 200 facing the floating mechanism 300, and the sensing piece 430 is installed on one 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 piece 430 when the floating mechanism 300 rises to a predetermined height, thereby monitoring the liquid level of the concrete in the slot section. The sensing module 420 and the concrete pumping system 500 are electrically connected to the control module 410 to form a closed-loop control system.
[0048] More specifically, when the concrete in the slot section lifts the floating mechanism 300 from the initial position to the sensing position, the sensing module 420 senses the presence of the sensing piece 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 overfilling of concrete. The automated control process greatly improves the accuracy and reliability of the post-collapse concrete filling process of the underground continuous wall slot wall.
[0049] In the technical solution provided by the present application, through the cooperative action of the mobile base 100, the support frame 200, the floating mechanism 300, and the overfilling prevention detection mechanism 400, the operational limitations of the difficulty in controlling the concrete liquid level during the post-collapse concrete filling of the underground continuous wall slot wall are effectively solved. The mobile base 100 and the support frame 200 provide stability and maneuverability for the floating mechanism 300, while the floating mechanism 300 can float with the rising of the concrete liquid level and monitor the actual height of the concrete liquid level in the slot section in real time. The overfilling prevention detection mechanism 400 uses the sensing module 420 and the sensing piece 430 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 does this significantly improve the operation accuracy and reliability of the post-collapse concrete filling process of the underground continuous wall slot wall, but it also reduces the risk of human error and reaction delay, thereby ensuring the quality and efficiency of the post-collapse concrete filling of the underground continuous wall slot wall.
[0050] As an optional implementation of the present embodiment, the floating mechanism 300 can adopt a hollow structure to reduce weight and improve buoyancy. The sensing module 420 can use an optical sensor or a magnetic sensor in the prior art to improve the accuracy and response speed of sensing. The control module 410 can use a programmable logic controller (PLC) in the prior art to achieve more complex control logic and data recording functions.
[0051] In the embodiment of the present application, the floating mechanism 300 includes a floating plate 310 and a plurality of guide rods 320, the plurality of guide rods 320 are installed on the top of the floating plate 310 in a circumferential direction, each guide rod 320 extends in a vertical direction, each guide rod 320 is slidably connected with the support frame 200, the floating plate 310 is arranged below the support frame 200, and the sensing piece 430 is installed on the 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 piece 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 to refer to Figure 3 and Figure 4In the embodiment of the present application, the support frame 200 comprises a top plate 210 and a plurality of hollow limiting columns 220, which are installed at the bottom of the top plate 210 in a circumferential direction of the top plate 210, and the number of the hollow limiting columns 220 is consistent with the number of the guide rods 320 and is arranged one-to-one, and each guide rod 320 is slidably installed in the corresponding hollow limiting column 220 in a vertical direction.
[0053] Specifically, the top plate 210 serves as the main body of the support frame 200 and provides a solid installation basis for the plurality of hollow limiting columns 220. The plurality of hollow limiting columns 220 are installed in a circumferential direction of the top plate 210, which not only enhances the stability of the overall structure but also provides uniform distribution of guide channels for the guide rods 320.
[0054] The one-to-one arrangement of the hollow limiting columns 220 and the guide rods 320 ensures that each guide rod 320 has a dedicated guide channel. This effectively prevents the guide rods 320 from deviating or interfering during movement, thereby ensuring smooth movement of the floating mechanism 300 and improving the accuracy and reliability of the floating mechanism 300 in monitoring the liquid level of the concrete in the groove section. The guide rods 320 can freely slide in the corresponding hollow limiting columns 220 in a vertical direction, allowing the floating mechanism 300 to accurately follow the changes in the liquid level of the concrete and float upwards. At the same time, this structure also facilitates maintenance and replacement, 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 rods 320 and can move between the initial position in the groove section and the sensing position outside the groove section. This structure of the support frame 200 ensures that the floating mechanism 300 remains stable and accurate throughout the movement process. When the liquid level of the concrete rises, the floating mechanism 300 can smoothly float upwards until it reaches the sensing position and is sensed by the anti-overfilling detection mechanism 400.
[0056] As an optional implementation of the present embodiment, the hollow limiting columns 220 can be made of high-strength alloy materials to improve their wear resistance and service life. The surface of the guide rods 320 can be specially treated, such as chrome plating or coating with low-friction materials, to reduce friction between the hollow limiting columns 220 and improve the smoothness of movement.
[0057] In the embodiment of the present application, the top end of each hollow limiting column 220 extends beyond the top of the top plate 210, and the top of each guide rod 320 is installed with a limiting plate 321.
[0058] Specifically, the main role of the limiting plate 321 is to prevent the guide rod 320 from being completely pulled out of the hollow limiting column 220, ensuring that the floating mechanism 300 is always connected with the support frame 200. The disconnection or out-of-control condition that may occur during the lowering process of the floating mechanism 300 is effectively prevented, and the safety and reliability of the device are greatly improved.
[0059] In the embodiment of the present application, the concrete pumping system 500 comprises a concrete pump and a pump pipe, the concrete pump is electrically connected with the control module 410, the feeding port of the pump pipe is communicated with the concrete pump, the floating plate 310 is formed with a through opening 311 for inserting the pump pipe, the through opening 311 extends vertically, and the discharging port of the pump pipe is communicated with the through opening 311.
[0060] It should be noted that the concrete pumping system 500 is prior art.
[0061] Specifically, the through opening 311 formed on the floating plate 310 extends vertically, providing a movable channel for the pump pipe. The pump pipe can maintain a relatively fixed position when moving up and down on the floating mechanism 300, ensuring that concrete can be continuously delivered into the groove section, even if the delivery is not interrupted during the rising process of the floating mechanism 300. The problems such as pipe twisting or clogging during concrete delivery are greatly reduced.
[0062] Please continue to refer to Figures 1 to 4 In the embodiment of the present application, the top center of the top plate 210 is provided with an opening 211 for the pump pipe to pass through, and the top periphery of the top plate 210 is recessed to form a recess 212 for placing the pump pipe, and the discharging port of the pump pipe extends downward from the recess 212 into the through opening 311 through the opening 211.
[0063] Specifically, the opening 211 formed in the top center of the top plate 210 provides a channel for the pump pipe to pass through the top plate 210, so that the pump pipe can be directly connected to the through opening 311 of the floating mechanism 300 from above the support frame 200. It ensures that the path of the pump pipe is the shortest and most direct, reducing the resistance and bending encountered by the concrete during delivery.
[0064] The recess 212 formed by the recessing of the top periphery of the top plate 210 provides a stable placement position for the pump pipe, effectively preventing the pump pipe from moving laterally or vibrating excessively during operation. Moreover, the recess 212 can also help the operator to easily position and install the pump pipe, improving the operability of the device.
[0065] The outlet of the pump pipe extends downward from the groove 212 to the through hole 311 through the opening 211, forming a continuous concrete conveying channel. Not only does it ensure the continuity and stability of concrete conveying, but also allows 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 the initial position in the groove segment and the sensing position outside the groove segment, and the continuous channel formed by the opening 211 of the top plate 210 and the through hole 311 of the floating plate 310 ensures that the concrete conveying is not disturbed throughout the process. Improve 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 prolong the service life of the groove 212 integrally formed with it. The bottom of the groove 212 is slightly inclined to facilitate the drainage of accumulated water or impurities during construction work in rainy weather.
[0068] Please continue to refer to Figure 1 and Figure 4 In the embodiment of the present application, the number of mobile bases 100 is two, and the two mobile bases 100 are arranged on opposite sides of the top of the groove segment; each mobile base 100 includes a trolley 110 and a connecting frame 120, the bottom end of the connecting frame 120 is installed on the trolley 110, and the top end of the connecting frame 120 is connected with the support frame 200 and is used to suspend the support frame 200 on the top of the groove segment.
[0069] It should be noted that the trolley 110 is a prior art.
[0070] Specifically, the number of mobile bases 100 is two, and the two mobile bases 100 are arranged on opposite sides of the top of the groove segment. Ensure that the entire device can move smoothly on the road surface outside the top of the groove segment. Not only does it enhance the support of the overall structure, but it also improves the adaptability of the device, which can adapt to groove segments of different widths.
[0071] The trolley 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 groove segment, making it easy to adjust the position and perform detection work in different areas. And the bottom end of the connecting frame 120 is installed on the trolley 110, forming a stable foundation structure.
[0072] The top end of the connecting frame 120 is connected with the support frame 200 and is used to suspend the support frame 200 at the top of the groove section. The cantilevered installation of the support frame 200 is achieved, so that the entire detection device can be suspended above the groove section without interfering with the construction work or structure in the groove section. By suspending the support frame 200 at the top of the groove section through the connecting frame 120, not only the stability of the detection device is ensured, but also the flexibility is improved, so that the device can be easily adjusted in height and position as needed.
[0073] In the embodiment of the present application, the top of the trolley 110 is formed with a sliding groove 111, and the bottom end of the connecting frame 120 is slidably installed in the sliding groove 111 in the horizontal direction, and the top end of the connecting frame 120 is hinged with the support frame 200.
[0074] Specifically, the sliding groove 111 provides a horizontal movement channel for the bottom end of the connecting frame 120, and this horizontal direction is perpendicular to the extension direction of the groove section. The connecting frame 120 can freely slide in the sliding groove 111 in the horizontal direction, thereby realizing the position adjustment capability of the device in the horizontal direction. To adapt to groove sections of different sizes.
[0075] The bottom end of the connecting frame 120 is slidably installed in the sliding groove 111, which not only increases the flexibility of the entire structure, but also improves the stability of the device. This sliding connection allows the connecting frame 120 to be adjusted horizontally in a small range as needed while maintaining stable support. It is conducive to dealing with irregular shapes of the groove section or the need for precise positioning.
[0076] The top end of the connecting frame 120 is hinged with the support frame 200, so that the support frame 200 can rotate at a certain angle relative to the connecting frame 120. It is conducive to adapt to different construction environments and detection needs, 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 support frame 200 through this hinged structure without moving the entire device.
[0077] The embodiment not only improves the accuracy and adaptability of the device, but also enhances the operation convenience. The operator can realize the horizontal fine adjustment through the sliding groove 111 and the vertical angle adjustment through the hinge, so as to quickly and accurately position the detection device to the best 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 the embodiment of the present application, the mobile base 100 further comprises a driving member 130, the driving member 130 is installed on the trolley 110, the output end of the driving member 130 is connected with 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 sliding groove 111 in the horizontal direction.
[0079] Specifically, the driving member 130 automates the horizontal adjustment process that would otherwise require manual operation, improving the accuracy and efficiency of the device adjustment. The driving member 130 is mounted on the trolley 110, ensuring that the driving member 130 forms a stable whole with the trolley 110, reducing vibration and error during movement.
[0080] The output end of the driving member 130 is connected to the bottom end of the connecting frame 120, enabling the driving member 130 to directly control the horizontal movement of the connecting frame 120 within the chute 111. By precisely controlling the output of the driving member 130, the operator can achieve fine adjustment of the position of the connecting frame 120, improving the precise positioning capability of the device.
[0081] As an optional implementation, the driving member 130 can use a stepper motor in existing technology to achieve higher precision position control. The driving member 130 can be equipped with an encoder for precise monitoring of the position of the connecting frame 120. In addition, a position feedback mechanism can be added to the control system of the driving member 130, so that the entire adjustment process forms a closed-loop control system, further improving the positioning accuracy.

[0084] Step S20, adjust the floating mechanism 300 at the initial position, so that the floating mechanism 300 extends into the slot section;
[0085] Step S30, control the concrete pumping system 500 to transport concrete into the slot section;
[0086] Step S40, when the liquid level of the concrete in the slot section rises, the inductor 430 on the floating mechanism 300 moves with the floating mechanism 300 from the initial position to the sensing position, so that the sensing module 420 senses the inductor 430 to generate the sensing signal, and sends the sensing signal to the control module 410;
[0087] Step S50, after the control module 410 receives the sensing signal, controls the concrete pumping system 500 to stop pumping concrete to prevent over-pumping phenomenon.
[0088] Specifically, step S10 ensures that the detection device can be accurately positioned at the location of the section of the trench 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 section of the trench. In preparation for the detection process, it is ensured 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 into the section of the trench. The actual refilling process begins. By controlling the concrete pumping system 500, it can be ensured that the concrete is delivered into the section of the trench at an appropriate rate and quantity.
[0091] In step S40, when the concrete liquid level in the section of the trench rises, the inductor 430 on the floating mechanism 300 moves with the floating mechanism 300 from the initial position to the sensing position. As the concrete liquid level rises, the floating mechanism 300 is gradually raised until the inductor 430 reaches the sensing range of the sensing module 420, causing the sensing module 420 to generate a sensing signal and send it 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 pumping concrete, so as to prevent overfilling. Automation control is achieved, ensuring that refilling is stopped in time when the concrete reaches the predetermined height, effectively preventing overfilling.
