Description

Technical Field

[0001] The present invention belongs to the technical field of dam safety maintenance, and in particular relates to an integrated system and method for detecting and blocking underwater seepage points in a dam. Background Art

[0002] In dam maintenance projects, sealing seepage points is a key link in ensuring the safe operation of the dam and is directly related to the stability and service life of water conservancy facilities.

[0003] Currently, underwater seepage points in dams are usually located using detection equipment such as sonar and radar. Workers then dive to the designated area and drill holes at the seepage points using underwater drilling equipment. Finally, grouting equipment, operated manually or by a robotic arm, injects sealing material into the gaps to seal the holes.

[0004] However, in the existing dam seepage point plugging equipment, due to the relatively simple injection method, it is difficult to control the filling state of the plugging material during the plugging process, which can easily lead to uneven material distribution, the appearance of voids or cracks, and affect the plugging effect and durability. At the same time, there is a lack of effective real-time monitoring means, which makes it impossible for workers to grasp the progress of the plugging and often requires repeated diving inspections, which not only increases labor costs and operation time, but also poses a major safety hazard and cannot meet the needs of efficient and safe dam maintenance. In view of this, the present invention is specially proposed. Summary of the Invention

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] Preferably, a fixing ring is fixedly connected to the sleeve, and a sealing airbag is provided on the fixing ring. The sealing airbag is arranged in a ring shape and is sleeved on the sleeve; an air supply pipe with a valve switch is connected to the sealing airbag, and the cross-section of the sealing airbag is arranged in an L shape.

[0009] In order to inflate and pressurize the sealing airbag when sealing the seepage point gap, further, the sleeve is fixedly connected with a first conduit and a second conduit, and the sleeve is connected to the sealing airbag through the second conduit.

[0010] Preferably, it also includes a feed pump and a storage box placed on the ground or on a transport vehicle, the input end of the feed pump is connected to the storage box, the output end of the feed pump is connected to the input end of the feed pipe one through the feed pipe three, and the alarm is fixedly installed on the storage box.

[0011] Furthermore, a mixing tank is fixedly installed on the suspension frame, and a feeding cavity, a suction cavity and a mixing cavity are provided in the mixing tank. The suction cavity is respectively connected with the output end of the feeding cavity and the input end of the mixing cavity. The feeding cavity is arranged in a cone shape, and the output end of the feeding pipe three is connected with the feeding cavity, and the input end of the feeding pipe one is connected with the output end of the mixing cavity; a storage tank is arranged on one side of the mixing tank; a feeding pipe two with a control valve has one end fixedly connected with the storage tank, and the other end is connected with the suction cavity.

[0012] In order to clean the moss attached to the inner wall of the seepage point gap before sealing the seepage point gap, a submersible pump is fixedly installed on the sleeve, and the output end of the submersible pump is connected to the feed cavity through a water pipe.

[0013] In order to mix the polyurethane and triethanolamine solutions input into the mixing chamber and reduce the viscosity of the polyurethane, a rotating shaft is further provided in the mixing chamber, one end of the rotating shaft passes through the feed chamber and is rotatably connected to the inner wall of the feed chamber, and a disturbance rod is fixedly connected to the outer wall of one end of the rotating shaft located in the mixing chamber.

[0014] In order to drive the rotating shaft to rotate, further, an impeller is fixedly installed on one end of the rotating shaft located in the material delivery cavity, and the output ends of the water delivery pipe and the material delivery pipe correspond to the impeller.

[0015] In order to facilitate the sinking of the suspension frame as a whole into the water through the lifting rings, preferably, lifting rings are symmetrically fixedly connected to both ends of the suspension frame, and the lifting rings can cooperate with external lifting equipment to enable the suspension frame as a whole to be sunk into the water, and then the sealing material is injected into the seepage point gaps of the dam body through the grouting pipe and grouting nozzle.

[0016] The method of using the integrated system for detecting and blocking underwater seepage points in dams includes the following steps:

[0017] Step 1: Use radar detection equipment to scan the dam body, determine the location of the leakage point, and then use drilling equipment to drill holes at the leakage point;

[0020] Step 4: The polyurethane solution is delivered to the grouting pipe through the feed pipe 1. The solution flows into the gap and solidifies, expands and seals it. During this period, the piston disc moves under pressure, and the gas in the compression sleeve is replenished to the sealing airbag through the conduit 2;

[0021] Step 5: The alarm will indicate the plugging progress by the contact status of the conductive ring 1 and the conductive ring 2. When the contact occurs, the alarm will start flashing, indicating that the plugging operation is completed.

[0022] Step 6: Release the sealed airbag gas, and then use the lifting equipment to recover the equipment.

[0023] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0024] The present invention fills the sleeve and the drilled hole gap after the sealing airbag is inflated, which can not only isolate water seepage in the dam body and create a dry and solidified environment for the sealing material to ensure the sealing effect, but also firmly fix the equipment, resist the impact of water flow, and maintain the stability of the grouting operation. The buffer zone formed by its L-shaped design further enhances the impact resistance. The spring and the piston disc work together to make the polyurethane evenly stressed during expansion, slowly and fully filling the gap to avoid the occurrence of voids and cracks, ensuring that the sealing material is dense and uniform, and improving the sealing effect. At the same time, the gas in the sleeve is compressed during the movement of the piston disc to replenish the sealing airbag, ensuring that the airbag maintains a good sealing and fixing effect throughout the grouting process. In addition, the conductive ring is combined with the alarm to provide real-time feedback on the sealing status. The staff can grasp the progress of the operation without diving, which not only improves work efficiency, but also avoids diving risks and ensures personnel safety.

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0035] Example 1: Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5, the integrated system for underwater seepage point detection and plugging of a dam includes a suspension frame 1, and also includes: a sleeve 2, fixedly connected to the suspension frame 1; a piston disc 202, slidably connected in the sleeve 2; a spring 206 arranged in the sleeve 2, one end of which is fixedly connected to the inner wall of the sleeve 2, and the other end is fixedly connected to the piston disc 202; a grouting pipe 203 slidably connected to the sleeve 2 and fixedly connected to the piston disc 202; a grouting nozzle 204, fixedly connected to the output end of the grouting pipe 203; a feed pipe 207, connected to the input end of the grouting pipe 203; a conductive ring 1 5 and a conductive ring 2 501, both arranged in the sleeve 2, for controlling the switch of an external alarm 502, wherein the conductive ring 1 5 is fixedly mounted on the piston disc 202, and the conductive ring 2 501 is fixedly mounted on the inner wall of the sleeve 2, and the alarm 502 is used to prompt the staff of the blocking status of the seepage point gap; a ring-shaped sealing gasket 205 is arranged on the grouting nozzle 204.

[0036] A fixing ring 201 is fixedly connected to the sleeve 2, and a sealing airbag 3 is provided on the fixing ring 201. The sealing airbag 3 is annular and sleeved on the sleeve 2; an air supply pipe 301 with a valve switch is connected to the sealing airbag 3, and the cross-section of the sealing airbag 3 is L-shaped.

[0037] The sleeve 2 is fixedly connected with a conduit 1 302 and a conduit 2 303 , and the sleeve 2 is connected with the sealing airbag 3 through the conduit 2 303 .

[0038] Both ends of the suspension frame 1 are symmetrically fixed with lifting rings 101, which can cooperate with external lifting equipment to sink the suspension frame 1 as a whole into the water, and then inject sealing materials into the seepage gaps of the dam body through the grouting pipe 203 and the grouting nozzle 204.

[0039] The method of using the integrated system for underwater seepage detection and plugging of dams is as follows: when using it, first use radar detection equipment to conduct a comprehensive scan of the dam body to accurately detect whether there is leakage in the dam body and the specific location of the leakage point. After the leakage point is located, the staff dives underwater and uses professional drilling equipment to drill holes at the leakage point, so that the equipment can be used to plug the leakage point gap later. Radar detection can avoid blindly searching for leakage points, saving manpower and time costs, and improving work efficiency;

[0040] When plugging, first use the lifting equipment in conjunction with the lifting ring 101 to sink the suspension frame 1 as a whole into the water. The lifting equipment can accurately control the position of the suspension frame 1 and move it to the drilled hole position. The setting of the lifting ring 101 ensures the stability and safety of the suspension frame 1 as a whole during the lifting process, thereby facilitating the accurate arrival of the equipment at the predetermined position, reducing the difficulty of underwater positioning, and improving the convenience and accuracy of operation.

[0041] The staff dives underwater again and inserts the grouting nozzle 204 into the drill hole, with the insertion depth matching the drilling depth. At this time, the sleeve 2 is partially inserted into the drill hole, and the fixing ring 201 contacts the surface of the dam body. Then, air is inflated into the sealing airbag 3 through the air supply pipe 301 with a valve switch. The sealing airbag 3 is L-shaped and can fill the gap between the sleeve 2 and the drill hole after expansion. On the one hand, it effectively prevents water in the dam body from continuously seeping into the drill hole, ensuring that the sealing material solidifies in a relatively dry environment and improving the sealing effect. On the other hand, the inflated airbag generates an outward supporting force, which firmly fixes the suspension frame 1 as a whole on the dam body, preventing the equipment from shaking or shifting due to water flow impact or other external forces during the grouting process, thereby ensuring the stability of the grouting operation. At the same time, the L-shaped airbag forms a buffer zone between the fixing ring 201 and the surface of the dam body, which can alleviate the impact of water flow on the equipment and further enhance the stability of the equipment.

[0042] Then, the polyurethane solution is transported to the grouting pipe 203 through the feed pipe 207, and the solution flows into the seepage point gap of the dam body through the grouting nozzle 204. At this time, the isocyanate group in the polyurethane solution contacts the residual water in the gap, triggering a curing reaction and starting to expand. The seepage point gap is sealed by utilizing its good adhesion and waterproof properties. The elasticity and durability of the polyurethane can adapt to possible slight deformation of the dam body and maintain a long-term sealing effect. As the polyurethane gradually expands, the pressure in the gap increases, pushing the piston disc 202 to overcome the elastic force of the spring 206 in the sleeve 2 and slide out of the borehole. In this process, the gas stored in the sleeve 2 is gradually compressed, and the compressed gas is transported through the conduit 2 303 The air is fed into the sealing airbag 3, so that the sealing airbag 3 is continuously replenished with air during the grouting process and maintains a good expansion state. On the one hand, the continuous and stable sealing effect prevents water in the dam body from seeping into the drill hole and affecting the curing of the polyurethane. On the other hand, the fixing effect of the suspension frame 1 on the dam body is enhanced, preventing the equipment from shifting due to fluctuations in the grouting pressure, and ensuring the stable progress of the grouting operation. At the same time, the elastic force of the spring 206 provides reverse resistance, so that the polyurethane is subjected to uniform pressure during the expansion process, so that the polyurethane can slowly and fully fill the seepage point gap, avoiding the formation of cavities or cracks due to excessive local pressure caused by excessive expansion, ensuring the density and uniformity of the sealing material, and improving the sealing effect.

[0043] During the grouting process, the sealing gasket 205 on the grouting nozzle 204 further enhances the sealing performance with the borehole wall, preventing the polyurethane solution from leaking from the contact point between the grouting nozzle 204 and the borehole under high pressure, effectively reducing material waste and ensuring that all the polyurethane solution is used to seal the gap;

[0044] When the conductive ring 1 5 is not in contact with the conductive ring 2 501, the alarm 502 is off, indicating that the plugging operation is in progress. As the piston disc 202 slides out of the borehole, when the conductive ring 1 5 is in contact with the conductive ring 2 501, the alarm 502 is triggered and starts flashing, indicating that the plugging operation is complete. This real-time monitoring function eliminates the need for workers to repeatedly dive to check, and they can promptly grasp the plugging progress and effect on the surface, which not only improves work efficiency, but also avoids the safety risks of diving operations and ensures the personal safety of workers.

[0045] When the plugging operation is completed, the operator opens the valve on the air supply pipe 301, and the gas in the sealing airbag 3 begins to be released. The airbag gradually shrinks, which can release the fixing effect of the sealing airbag 3 on the suspension frame 1 and eliminate the pressure between the airbag and the dam surface and the sleeve 2. After the gas in the sealing airbag 3 is released, the previously compressed spring 206 begins to release elastic potential energy, generating thrust to push the piston disc 202 to move in the sleeve 2 toward the side away from the conductive ring 2 501. During the movement of the piston disc 202, the external gas is sucked into the sleeve 2 through the conduit 1 302, so that the air pressure in the sleeve 2 returns to a balanced state, preparing for the next operation. After completing the above operations, with the help of lifting equipment and the lifting rings 101 at both ends of the suspension frame 1, the suspension frame 1 as a whole can be lifted and recovered steadily from underwater.

[0046] It should be noted that the grouting pipe 203, the conduit 1 302, and the conduit 2 303 are all provided with a one-way valve;

[0047] During specific implementation, in order to prevent the feed pipe 207 from interfering with the movement of the piston disc 202, a stretchable and shrinkable hose is required.

[0048] Example 2: Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The integrated system for detecting and blocking underwater seepage points in a dam is basically the same as that in Example 1, and further includes a feed pump 407 and a storage box 408 placed on the ground or on a transport vehicle. The input end of the feed pump 407 is connected to the storage box 408, and the output end of the feed pump 407 is connected to the input end of the feed pipe 1 207 through the feed pipe 3 406. The alarm device 502 is fixedly installed on the storage box 408.

[0049] A mixing tank 4 is fixedly mounted on the suspension frame 1, and a feeding chamber 401, a suction chamber 402 and a mixing chamber 403 are provided in the mixing tank 4. The suction chamber 402 is respectively connected with the output end of the feeding chamber 401 and the input end of the mixing chamber 403. The feeding chamber 401 is conically arranged, and the output end of the feeding pipe three 406 is connected with the feeding chamber 401, and the input end of the feeding pipe one 207 is connected with the output end of the mixing chamber 403; a storage tank 404 is arranged on one side of the mixing tank 4; a feeding pipe two 405 with a control valve is fixedly connected with the storage tank 404 at one end, and is connected with the suction chamber 402 at the other end.

[0050] A submersible pump 7 is fixedly mounted on the sleeve 2 , and an output end of the submersible pump 7 is connected to the feed cavity 401 through a water pipe 701 .

[0051] Before sealing the seepage point gap, first repeat the operating steps of inserting the grouting nozzle 204 into the drill hole and fixing the equipment with the sealing airbag 3 in the above embodiment 1, start the submersible pump 7, which draws water from the dam and transports it to the feeding chamber 401 of the mixing tank 4 through the water pipe 701. During the process of water flowing from the output end of the feeding chamber 401 to the mixing chamber 403, due to the rapid flow of water, a negative pressure is formed in the suction chamber 402. At this time, the control valve on the feeding pipe 2 405 is opened, and the triethanolamine solution auxiliary material in the storage tank 404 enters the mixing chamber 403 through the feeding pipe 2 405 through the suction chamber 402 under the dual action of negative pressure and its own gravity. 03, water and triethanolamine solution are brought into contact and mixed, and the mixed cleaning liquid is injected into the gap through the feed pipe 207, the grouting pipe 203 and the grouting nozzle 204. The high-pressure flushing of water and the chemical reaction of the auxiliary materials work together to clean the moss. Taking triethanolamine as an example, its alkalinity can destroy the cell structure of the moss, and its characteristic of reducing surface tension allows the mixed liquid to penetrate better and loosen the moss. The impact force of the high-pressure water is then used to flush it out of the gap. Compared with single high-pressure water flushing, this combined cleaning method can more efficiently remove stubborn moss in the gap, avoid moss residue affecting the adhesion of the subsequent polyurethane sealing material to the gap surface, ensure that the sealing material can be closely combined with the gap, and improve the sealing quality;

[0052] After the moss is cleaned, the submersible pump 7 is turned off and the feed pump 407 is started to feed the polyurethane solution in the storage box 408 to the feed chamber 401 through the feed pipe three 406. In the process of the polyurethane solution flowing from the output end of the feed chamber 401 to the mixing chamber 403, negative pressure is formed again in the suction chamber 402. At this time, the control valve on the feed pipe two 405 is opened, and the triethanolamine solution auxiliary material in the storage tank 404 enters the mixing chamber 403 through the feed pipe two 405 through the suction chamber 402 under the dual action of negative pressure and its own gravity. In the mixing chamber 403, the polyurethane solution and the triethanolamine solution are contacted and mixed, which reduces the viscosity of the polyurethane solution and improves the fluidity. When the mixed liquid is fed into the seepage point gap through the grouting nozzle 204, it has better fluidity and can be filled into every corner of the gap more smoothly, thereby improving the filling density, reducing the gaps and defects in the gap, and thus enhancing the sealing effect.

[0053] Example 3: Reference Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 The integrated system for detecting and plugging underwater seepage points in dams is basically the same as that in Example 1. Furthermore, a rotating shaft 6 is provided in the mixing chamber 403. One end of the rotating shaft 6 passes through the feeding chamber 401 and is rotatably connected to the inner wall of the feeding chamber 401. A disturbance rod 601 is fixedly connected to the outer wall of one end of the rotating shaft 6 located in the mixing chamber 403.

[0054] An impeller 602 is fixedly mounted on one end of the rotating shaft 6 located in the material delivery cavity 401 , and the output ends of the water delivery pipe 701 and the material delivery pipe 406 both correspond to the impeller 602 .

[0055] When cleaning the moss attached to the gaps in the seepage points, the water flows through the feeding chamber 401 and impacts the impeller 602, driving the rotating shaft 6 to rotate, thereby causing the disturbance rod 601 located in the mixing chamber 403 to stir and mix the water and the triethanolamine solution, so that the water and the triethanolamine solution are fully mixed, and the alkalinity of the triethanolamine is evenly exerted, effectively destroying the moss cell structure, thereby helping the high-pressure water to better remove the stubborn moss in the gaps.

[0056] When the seepage point gap is blocked, when the polyurethane solution passes through the feed cavity 401, the impeller 602 is impacted by the flow of the polyurethane solution, continuously driving the rotating shaft 6 and the disturbance rod 601 to rotate, so that the polyurethane solution and the triethanolamine solution in the mixing cavity 403 are fully stirred, ensuring that the polyurethane solution and the triethanolamine solution are fully mixed, so that the triethanolamine is evenly dispersed in the polyurethane solution, effectively reducing its viscosity, and significantly improving its fluidity, so that the mixed liquid with better fluidity can more fully fill the gap when injected into the gap, reduce gaps and defects, and further improve the blocking effect.

[0057] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as above with the preferred embodiment, it is not intended to limit the present invention.

When the contact occurs, the alarm (502) starts flashing, indicating that the plugging operation is completed. Step 6: Release the gas from the sealed airbag (3), and then use a lifting device to recover the equipment.
