DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention. For ease of description, the terms "upper" and "lower" will be used in the following text in the same direction as in the accompanying drawings, but this does not constitute a limitation of the present invention.

[0018] Combine Figures 1 to 4 The underground continuous wall plugging device 10 of the present invention is described. It is detachably connected to the important nodes or key parts of the steel cage 1 of the underground continuous wall. It includes a plugging material package 11, a hydraulic promotion package 12, a positioning device 15, a detection component 16 and a back-end processing platform. The hydraulic promotion package 12 is arranged in the plugging material package 11, the positioning device 15 and the detection component 16 are fixed to the outer wall of the plugging material package 11, and the positioning device 15 and the detection component 16 are respectively connected to the back-end processing platform signal.

[0019] The underground continuous wall plugging device of the present invention includes a plugging material package 11 connected to an important node or key position of the underground continuous wall steel cage 1, a hydraulic booster package 12 arranged in the plugging material package 11, and a positioning device 15 and a detection component 16 fixed to the outer wall of the plugging material package 11 and connected to the back-end processing platform signal. The back-end processing platform realizes remote automatic control of the hydraulic booster package 12, the positioning device 15 and the detection component 16 through the built-in intelligent control system, and synchronously performs data recording and data analysis; during the on-site construction of the underground continuous wall, the detection component 16 monitors in real time whether there is water seepage in the underground continuous wall and transmits the monitoring data to the back-end processing platform. When the detection result is abnormal, the positioning device 15 is used to accurately determine the leakage area. The position and depth of the underground continuous wall are detected and three-dimensional coordinates are generated. The back-end processing platform remotely controls the hydraulic promotion package 12 to puncture. The liquid inside the hydraulic promotion package 12 contacts the plugging material of the plugging material package 11, triggering a chemical reaction and forming a high-viscosity grouting liquid. The plugging material package 11 is ruptured due to the expansion of the grouting liquid. The grouting liquid quickly flows out and fills the leaking area, thereby quickly solidifying the leaking area. The underground continuous wall plugging device 10 integrates detection, positioning and plugging functions in one, and can grasp the leakage situation of the underground continuous wall in real time and dynamically, realizing the rapid identification, precise positioning and rapid plugging of the leakage point. It also realizes remote monitoring and automated operation, has the advantages of high efficiency, precision, intelligence and environmental protection, improves construction efficiency, reduces engineering risks, and has good economic and social benefits. The present invention is suitable for rapid detection, precise positioning and efficient plugging construction of underground continuous wall leakage points.

[0020] like Figure 2 As shown, the detection component 16 includes a signal-connected infrared thermal imaging device 14, a high-precision temperature and humidity sensor, and a data processor. Moisture penetration can cause uneven temperature distribution on the concrete surface. The infrared thermal imaging device 14 can quickly locate the leakage point. The temperature and humidity sensor is used to monitor the temperature and humidity changes on the wall surface in real time and identify the leakage area. The data processor amplifies the electrical signal received by the sensor and converts it into a digital signal, and maps the digital signal into a color thermal image through an algorithm.

[0021] like Figure 2 As shown, the detection component 16 also includes a pressure and flow sensor for monitoring the pressure and flow of the grouting liquid flowing out of the plugging material package 11.

[0022] like Figure 2 As shown, the outer wall of the sealing material package 11 is also provided with a nozzle (not shown in the figure), the nozzle outlet is directed toward the potential leakage point, so that the grouting liquid that expands after the chemical reaction can be injected into the leakage area through the nozzle channel in a targeted manner. The sealing material of this embodiment is water-soluble polyurethane, etc.

[0023] like Figure 3As shown, the hydraulic booster pack 12 comprises a sealed bag, a liquid filled in the bag, and a puncture mechanism 12a connected to the outer wall of the sealed bag. The puncture mechanism 12a is signal-connected to a back-end processing platform, which remotely controls the puncture mechanism 12a to puncture the sealed bag, allowing the liquid inside to flow out and come into contact with the plugging material, resulting in a chemical reaction. In this embodiment, the liquid in the hydraulic booster pack 12 is water, for example.

[0024] like Figure 4 As shown, the underground continuous wall plugging device 10 also includes a connector 17. One side of the connector 17 is fixed to the plugging material package 11, and the other side is detachably connected to the reinforcement cage 1 of the underground continuous wall. The connector 17 of this embodiment is in the form of a fixed hook. The curved hooks at both ends of the fixed hook are hung on the steel bars of the reinforcement cage 1. The other side of the fixed hook is covered with adhesive, and the plugging material package 11 is attached to the fixed hook, making it convenient and quick to disassemble.

[0025] Combine Figures 1 to 4 The following are the steps to use the underground continuous wall leak plugging device of the present invention: S1, installation of underground continuous wall leak-proof device 10: like Figure 1 As shown, the underground continuous wall plugging device 10 is installed at an important node or key position of the underground continuous wall reinforcement cage 1; the positioning module of the positioning device 15 is initialized, the actual installation position of the underground continuous wall plugging device 10 is matched with the positioning module, and the actual installation position of the underground continuous wall plugging device 10 is recorded in the underground engineering three-dimensional model; S2, detect leakage area: like Figure 2 As shown, the detection component 16 monitors the presence of water seepage in the underground continuous wall in real time and transmits the monitoring data to the back-end processing platform. The back-end processing platform uses a data analysis algorithm to mark abnormal areas as potential leakage areas; the positioning device 15 accurately locates and deeply detects the potential leakage areas to obtain the three-dimensional coordinates of the leakage areas; and based on the actual working conditions at the construction site, the location information of the leakage areas is accurately mapped to the three-dimensional model or engineering drawings. S3, plugging the leakage area: like Figure 2 As shown, according to the three-dimensional coordinates of the leakage area, the back-end processing platform remotely controls the puncture mechanism 12a of the hydraulic promotion package 12 in the corresponding underground continuous wall plugging device 10 to extend and puncture the sealing bag. After the liquid inside the hydraulic promotion package 12 contacts the plugging material, a chemical reaction is triggered to form a high-viscosity grouting liquid. The plugging material package 11 ruptures due to the expansion of the grouting liquid, and the grouting liquid flows out and fills the leakage area, thereby quickly solidifying the plugging area.

[0026] The method for using the underground continuous wall plugging device of the present invention is as follows: first, when manufacturing the steel cage 1 of the underground continuous wall, multiple underground continuous wall plugging devices 10 are installed at important nodes or key parts of the steel cage 1. During the on-site construction of the underground continuous wall, the detection component 16 monitors in real time whether there is water seepage in the underground continuous wall and transmits the monitoring data to the back-end processing platform. When the detection result is abnormal, the positioning device 15 is used to accurately locate and deeply detect the leakage area and generate three-dimensional coordinates. The back-end processing platform remotely controls the hydraulic promotion package 12 to puncture, and the hydraulic promotion package 1 2 After the internal liquid contacts the plugging material of the plugging material package 11, a chemical reaction is triggered to form a high-viscosity grouting liquid. The plugging material package 11 ruptures due to the expansion of the grouting liquid, and the grouting liquid quickly flows out and fills the leakage area, thereby quickly solidifying the leakage area. This method of use can dynamically grasp the leakage situation of the underground continuous wall in real time, realize the rapid identification, precise positioning and rapid plugging of the leakage point, and realize remote monitoring and automated operation. It has the advantages of high efficiency, precision, intelligence and environmental protection, improves construction efficiency, reduces engineering risks, and has good economic and social benefits.

[0027] In step S2, the infrared thermal imaging device 14 is used to monitor the surface of the underground continuous wall in real time, detect the temperature distribution on the wall surface, identify abnormal temperature areas, and a high-precision temperature and humidity sensor is used to check the humidity changes on the wall surface in real time to further confirm the leakage area.

[0028] The step S3 also includes: monitoring the pressure and flow of the grouting liquid in real time through pressure and flow sensors to ensure that the grouting liquid after the chemical reaction fully fills the leakage channel; after the grouting liquid solidifies, using the detection component 16 to perform a secondary detection on the leakage area to confirm the plugging effect, so as to quickly and promptly take plugging measures when leakage occurs, providing sufficient time for the construction personnel to carry out subsequent plugging work.
