[0020] This invention provides a directional filling device for seepage channels in dikes, such as... Figure 1-6As shown, the system includes a main mounting frame 101. A fixed connecting seat 111 is fixedly installed at the bottom of the main mounting frame 101. An intermediate connecting rod 113 is fixedly installed at the lower end of the fixed connecting seat 111. A detection drive seat 112 is fixedly installed at the lower end of the intermediate connecting rod 113. A detection mounting cavity 121 with an outward opening is provided at the bottom of the detection drive seat 112. A detector lifting seat 123 that can be raised and lowered is provided in the detection mounting cavity 121. A geological detection sensor 119 is installed at the lower end of the detector lifting seat 123. The geological detection sensor 119 is used for geological detection. One end of the geological detection sensor 119 is electrically connected to a detection signal cable 124 for signal transmission. Several vertical injection guide tubes 120 are installed at the bottom of the detection mounting cavity 121. An injection outlet 125 with an downward opening is provided at the lower end of the injection guide tube 120. The injection outlet 125 is used to guide the injection material.

[0021] It should be further explained that the geological detection sensor 119 integrates a miniature geological detection sensor. During drilling or travel, it can identify changes in the density and moisture content of the soil ahead in real time, and accurately locate the direction, diameter, and branches of the seepage channel.

[0022] Furthermore, the main mounting frame 101 is fixed with two crossbeams 104 on both sides. The crossbeams 104 on both sides are symmetrically positioned. A lateral support arm 103 is fixed on one side of the crossbeam 104. An arc-shaped handheld part 102 is provided below the outer end face of the lateral support arm 103. The arc-shaped handheld part 102 is arc-shaped to facilitate the handholding of the staff.

[0023] Furthermore, a vertical guide tube 117 is fixedly provided on the top of the main mounting frame 101, and a protective sleeve 116 is fitted on the upper part of the outer end face of the vertical guide tube 117. A top connector 109 is installed on the top of the protective sleeve 116.

[0024] Furthermore, a storage box 106 is provided above the vertical guide pipe 117. An inclined support rod 105 is installed and connected to the bottom of the storage box 106. The other end of the inclined support rod 105 is installed and connected to the top of the side support arm 103 and plays a supporting role.

[0025] Furthermore, the storage box 106 is provided with several multi-material bins 107, which are used to store different injection materials. Several material conveying hoses 108 are connected between the bottom and top connectors 109 of the storage box 106. The number of material conveying hoses 108 corresponds to the number of multi-material bins 107 and they are connected.

[0026] It should be further explained that the injection materials stored in the multi-material silo 107 include quick-setting water-blocking materials, high-strength consolidation materials, and flexible seepage prevention materials.

[0027] Furthermore, the vertical guide tube 117 is provided with a central guide cavity 129. One end of the central guide cavity 129 extends downward and communicates with the material guide channels 122 on each side. The top of the central guide cavity 129 is communicated with the material conveying hoses 108 on each side.

[0028] Furthermore, an intelligent proportioning valve assembly 130 is installed at the connection position between the material delivery hoses 108 on each side and the central guide cavity 129. The intelligent proportioning valve assembly 130 is used to control the connection status of the material delivery hoses 108, thereby enabling the use of different injection materials.

[0029] Furthermore, an integrated controller 115 is mounted and connected to the side of the main mounting frame 101. One end of the integrated controller 115 is electrically connected to a control harness 118, and the other end of the control harness 118 is electrically connected to an intelligent proportioning valve group 130 inside the sheath 116.

[0030] It should be further explained that the integrated controller 115 is connected to the detection signal cable 124. The processing module built into the integrated controller 115 analyzes the detection data and can transmit the information data to the operator's control terminal.

[0031] Furthermore, a screw mounting cavity 127 is connected to the top of the detector mounting cavity 121, and the top of the detector lifting seat 123 extends into the screw mounting cavity 127. A lifting drive screw 126 is rotatably provided in the screw mounting cavity 127, and the lifting drive screw 126 is threadedly connected to the detector lifting seat 123.

[0032] Furthermore, a micro drive motor 128 is fixedly installed inside one side wall of the screw mounting cavity 127, and the top of the lifting drive screw 126 is poweredly connected to the micro drive motor 128.

[0033] It is worth further explaining that when the micro drive motor 128 starts, it can drive the lifting drive screw 126 to rotate through the power connection. Then, the lifting drive screw 126 is threadedly connected to the detector lifting seat 123, which drives the detector lifting seat 123 to move up and down, thereby adjusting and controlling the detection position and direction of the geological detection sensor 119.

[0034] Furthermore, a bag-type sealing mechanism 114 is provided at the connection position of the fixed connecting seat 111. An inflatable annular airbag is fitted on the outer end face of the bag-type sealing mechanism 114. One end of the bag-type sealing mechanism 114 is electrically connected to an airbag control cable 110. The airbag control cable 110 extends outward and is electrically connected to the integrated controller 115.

[0035] It should be further explained that when the bag-type sealing mechanism 114 receives the start signal, it releases and inflates the annular airbag to isolate the channel into a closed cavity.

[0036] When in operation, the operator moves the entire device to the location to be detected on the dike using the curved handheld part 102. After the device is in place, the integrated controller 115 is activated, sending commands to the geological detection sensor 119 via the detection signal cable 124, and simultaneously sending control signals to the micro drive motor 128.

[0037] When the micro drive motor 128 starts, it drives the lifting drive screw 126 to rotate. Since the lifting drive screw 126 is threadedly connected to the detector lifting seat 123, it drives the detector lifting seat 123 to extend downward in the detection mounting cavity 121, so that the geological detection sensor 119 contacts the surface of the soil being measured or maintains a preset detection distance.

[0038] The geological detection sensor 119 begins operation, emitting detection signals into the soil and receiving reflected echoes to identify changes in the density and moisture content of the soil ahead in real time, accurately locating the geometric parameters such as the direction, diameter, and branches of the seepage channel. The detection signals are transmitted in real time to the integrated controller 115 via the detection signal cable 124. The processing module built into the integrated controller 115 analyzes the detection data and transmits the data to the user's control terminal.

[0039] Based on the parameters of the seepage channel obtained from the analysis, the staff can determine the location and direction of the channel. If the seepage channel is found to be located below or to the side of the current detection point at a certain distance, the staff can control the micro drive motor 128 to be restarted again through the integrated controller 115, and adjust the extension length of the detector lifting seat 123 through the lifting drive screw 126, so that the geological detection sensor 119 is always in line with the center line direction of the seepage channel, realizing exploration while walking and tracking.

[0040] When the geological detection sensor 119 confirms that the device has advanced to the section to be filled in the seepage channel, the integrated controller 115 sends a start signal to the bag-type sealing mechanism 114 through the airbag control cable 110. After receiving the signal, the bag-type sealing mechanism 114 releases and expands the inflatable annular airbag on its outer end face, tightly adhering to the inner wall of the seepage channel, sealing the top end of the section to be filled, and forming a closed filling cavity.

[0041] After the closed cavity is formed, the integrated controller 115 sends a control command to the intelligent proportioning valve group 130 through the control wiring harness 118 based on the channel environment information obtained from the previous detection (such as whether there is open flow, the degree of water seepage, the size of the cavity, etc.). The intelligent proportioning valve group 130 selectively opens the connection between the corresponding material conveying hose 108 and the central guide cavity 129 according to the command.

[0042] Different injection materials (such as quick-setting water-blocking materials, high-strength consolidation materials, flexible seepage-proof materials, etc.) stored in the multiple material bins 107 inside the storage tank 106 are transported to the top connector 109 via the corresponding material delivery hoses 108 under external pressure, and then enter the central guide cavity 129 in the vertical guide pipe 117. After the materials are mixed or flow sequentially in the central guide cavity 129, they are diverted downward through the material guide channel 122 to each of the vertical injection guide pipes 120, and finally released from the injection outlet 125 into the closed cavity isolated by the bag-type sealing mechanism 114.

[0043] During the injection process, the integrated controller 115 dynamically adjusts the opening status and duration of the intelligent proportioning valve group 130 according to a preset program or real-time feedback, to achieve gradient injection of different materials or on-demand proportioning. For example, if open flow is detected in the channel, the delivery hose 108 corresponding to the quick-setting water-blocking material is opened first, and the quick-setting material is injected to form a temporary plug to block the water flow. After the plug has solidified, the delivery hose 108 corresponding to the high-strength solidification material is opened, and the high-strength material is injected to permanently reinforce the main body of the channel. Finally, the delivery hose 108 corresponding to the flexible seepage-proof material is opened to form a flexible seepage-proof layer on the surface of the filler.

[0044] During the injection process, the geological detection sensor 119 can work intermittently to monitor the diffusion and compaction of the filling material in the closed cavity in real time, and transmit the monitoring data to the integrated controller 115 in real time. The integrated controller 115 processes the received data and converts it into information so that staff can intuitively judge the filling effect at the control terminal.

[0045] Once the monitoring data confirms that the filling cavity has been completely filled with material and has reached the preset density requirement, the integrated controller 115 closes the intelligent proportioning valve group 130 to stop the material injection. Subsequently, the bladder-type sealing mechanism 114 depressurizes, the inflated annular airbag contracts and resets, and the blockage of the channel is released.

[0046] The integrated controller 115 starts the micro drive motor 128 to rotate in the opposite direction, and drives the detector lifting seat 123 to retract and reset through the lifting drive screw 126, so that the geological detection sensor 119 is retracted into the detection installation cavity 121. The operator moves the device to the next position to be processed through the arc-shaped handheld part 102, and repeats the above steps to carry out continuous operation.

[0047] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
