Description

Technical Field

[0001] The present invention belongs to the technical field of dam body repair devices, and in particular relates to a reservoir leakage detection and repair device and method. Background Art

[0002] During the operation of the reservoir, the leakage of the dam has always been a key factor affecting the safety and stability of the reservoir. At present, the repair of reservoir dam leakage usually adopts the grouting method to seal the cracks in the reservoir dam.

[0003] The existing grouting method generally uses a drilling device to drill vertical or inclined grouting holes on the surface of the dam body, so that the drilled grouting holes are connected to the cracks. Then, by inserting the grouting equipment on the surface of the grouting holes, pressurized repair fluid is continuously injected. With this repair method, if there are multiple crack holes connected to each other in the grouting holes, the injected repair fluid is very likely to have a slurry phenomenon, resulting in uneven distribution of the repair fluid, some cracks cannot be effectively filled, and the repair effect is greatly reduced.

[0004] In addition, there are multiple cracks in the grouting hole, but they are not at the same height. At this time, the repair fluid entering the cracks is reduced again, and the repair fluid cannot fully penetrate into the cracks due to insufficient pressure, affecting the repair quality. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a dam repair device that can overcome the above problems or at least partially solve the above problems.

[0006] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a reservoir leakage detection and repair device, including a repair liquid storage tank and a repair liquid grouting device, wherein the repair liquid storage tank is connected to the liquid inlet end of the repair liquid grouting device, and further comprising:

[0007] A grouting repair pipe connected to the liquid outlet of the repair liquid grouting equipment;

[0008] The side grouting repair hole is arranged on the side of the grouting repair pipe near the bottom end and is connected to the infusion pipeline inside the grouting repair pipe;

[0009] Multiple groups of air bags are installed on the grouting repair pipe in a ring shape with equal intervals, and the multiple groups of air bags are respectively located on the upper and lower sides of the side grouting repair hole;

[0010] a pressure sensor, disposed in the airbag, for detecting pressure changes in the airbag;

[0011] The radar detection device is used to detect the location of cracks on the reservoir dam, and then a punching device is used to drill grouting repair holes near the cracks in the concrete dam. Multiple grouting repair holes are evenly arranged on the left and right sides of the cracks, and the drilling depth penetrates the deep cracks. Then the grouting repair tube is inserted into the grouting repair hole, and the outer diameter of the ring formed by the multiple groups of air bags arranged in a ring is larger than the inner hole of the grouting repair hole after being filled with air. At this time, if the air bag contacts the crack area, since the crack area is empty, the air bag will expand because it is in a compressed state. Then the pressure sensor detects the pressure change and inputs the information into the computer to record the position and size of the crack until it is inserted to the bottom and then moves from bottom to top. The air bag seals the upper and lower sides of the side grouting repair hole, and then the crack area is grouting repaired through the side grouting repair hole.

[0012] In order to facilitate the sealing of larger cracks, the grouting repair pipe is further provided with a slide groove, and a plurality of sliding rings are slidably connected to the slide groove. The airbag is installed on the sliding ring, and the sliding ring is installed with an electromagnet 1 and an electromagnet 2. The sliding ring can be fixedly connected to the grouting repair pipe through the electromagnet 1 and the electromagnet 2, and the different sliding rings can be moved closer to or away from each other under the action of opposite poles attracting each other and like poles repelling each other by the change of the magnetic poles between the electromagnet 1 and the electromagnet 2, so as to adjust the position of the sliding ring on the grouting repair pipe;

[0013] By inserting the grouting repair pipe into the grouting repair hole and detecting the crack position, some large cracks can be repaired by tightly fitting multiple sets of sliding rings to increase the longitudinal length of the annularly installed airbag, thereby sealing the larger cracks. At this time, when grouting repair is carried out, the grouting repair liquid can be concentrated and enter through the middle and lower areas of the large cracks.

[0014] In order to facilitate the auxiliary sealing of the grouting holes and reduce the repair fluid backflowing from the cracks, further, an opening is provided at the bottom of the grouting repair pipe, a pipe bottom sealing plate is threadedly connected to the opening, a bottom grouting repair hole is provided on the pipe bottom sealing plate, and a solenoid valve is installed on the bottom grouting repair hole.

[0015] Furthermore, a support frame is provided, to which a hydraulic device is fixedly connected, and the grouting repair pipe is installed on the telescopic end of the hydraulic device.

[0016] Furthermore, a mounting plate is fixedly connected to the telescopic end of the hydraulic device, a clamping plate is installed on the mounting plate by bolts, and a mounting hole is provided in the middle of the mounting plate and the clamping plate after the mounting plate and the clamping plate are spliced together, and the grouting repair pipe is installed in the mounting hole between the mounting plate and the clamping plate.

[0017] Furthermore, a mounting groove is provided in the mounting hole, and a mounting ring matching the mounting groove is provided on the grouting repair pipe.

[0018] Furthermore, an air nozzle is installed on the airbag.

[0019] In order to fill the side gap of the airbag, a sealing lip is further provided on the side of the airbag.

[0020] A reservoir leakage detection and repair method, used for a reservoir leakage detection and repair device, includes the following steps:

[0021] Step 1: Detect the crack locations on the reservoir dam using a radar detection device;

[0022] Step 2: Use a punching device to drill grouting repair holes near the cracks in the concrete dam. Multiple grouting repair holes are evenly arranged along the left and right sides of the cracks, and the drilling depth penetrates deep into the cracks.

[0023] Step 3: Install the support frame, install the grouting repair pipe on the support frame, and connect it to the repair liquid grouting equipment;

[0024] Step 4: Slowly insert the grouting repair pipe into the grouting repair hole through the hydraulic device on the support frame, and record the position and size of the crack through the changes in the pressure sensor in the airbag until it is inserted to the bottom of the grouting repair hole;

[0025] Step 5: Use the hydraulic device to adjust the position of the grouting repair hole on the side of the grouting repair pipe so that it can be aligned with the cracks located on the same plane. At this time, the air bag acts as a partition. Then, the high polymer repair liquid in the repair liquid storage tank is sucked out through the repair liquid grouting equipment and discharged through the side grouting repair hole to perform grouting repair on the cracks.

[0026] Step 6: Adjust the grouting position through the hydraulic device and repair the remaining cracks above by grouting;

[0027] Step 7: After the grouting repair is completed, the grouting repair hole is sealed, and the remaining grouting repair holes are repaired and sealed in turn.

[0028] Furthermore, the high polymer repair liquid is prepared by mixing a resin raw material of component A and a curing agent of component B;

[0029] The raw materials of component A resin are as follows:

[0030] Low viscosity flexible asphalt W200: 500kg,

[0031] Environmentally friendly aromatic oil for rubber: 100kg,

[0032] Rosin polyester polyol JC-380: 80kg,

[0033] wanenate PM200: 270kg,

[0034] February dibutyltin silicate: 1kg,

[0035] Additives: 49kg;

[0036] Component B curing agent: TMR-2;

[0037] The preparation process is as follows:

[0038] Add 500k low-viscosity flexible asphalt W200 and 100kg environmentally friendly rubber aromatic oil into a clean vacuum reactor, heat to 120℃, and evacuate for 2 hours to remove moisture. Stop evacuating when the moisture content reaches less than 1 / 1000.

[0039] Cool down to 80℃, add 80kg rosin polyester polyol JC-380 and 270kg polyphenylmethane polyisocyanate wanenate PM200, and stir thoroughly;

[0040] Use a peristaltic pump to gradually add 1 kg of catalyst dibutyltin disilicate and 49 kg of auxiliary agents, keep the temperature at 80°C, and then fully react for 2 hours under stirring to form the final product, which is then packaged and stored under nitrogen.

[0041] Then, before grouting repair, heat the prepared component A resin to 120°C, premix it with component B curing agent in a mass ratio of 100:0.05-0.1, and inject it into the repair liquid storage tank.

[0042] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: the present invention can assist in checking the location of cracks in the grouting repair hole by setting the airbag, and can simultaneously block the upper and lower spaces of the side grouting repair hole, so as to facilitate concentrated grouting of a part of the cracks and reduce incomplete grouting repair caused by insufficient pressure;

[0043] At the same time, by grouting some cracks one by one from bottom to top, compared with the traditional method of directly injecting repair fluid into the grouting repair hole, it can reduce the slurry bleeding phenomenon that is easy to occur during the grouting process due to the possible interconnection between multiple crack holes, thereby facilitating the repair of reservoir concrete cracks.

[0054] 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.

[0055] Example: Refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7A reservoir leakage detection and repair device and method include a repair liquid storage tank 1 and a repair liquid grouting device 2. The repair liquid storage tank 1 is connected to the liquid inlet end of the repair liquid grouting device 2, and also includes: a grouting repair pipe 4, which is connected to the liquid outlet end of the repair liquid grouting device 2; a side grouting repair hole 401, which is arranged on the side of the grouting repair pipe 4 near the bottom end and is connected to the infusion pipeline inside the grouting repair pipe 4; multiple groups of air bags 5, which are installed on the grouting repair pipe 4 in a ring shape with equal intervals, and the multiple groups of air bags 5 are respectively located on the upper and lower sides of the side grouting repair hole 401; a pressure sensor 6, which is arranged in the air bag 5 and is used to detect the pressure change of the air pressure in the air bag 5.

[0056] Through the radar detection device, the radar equipment can use the model LXY-GPR01 ground penetrating radar, which is used to quickly detect the location of cracks on the reservoir dam, and is easy to move. Then, through the punching device, the punching device can use an electric drill. Some deeper cracks require a hydraulic punching device. A hydraulic anchor drill can be used to drill grouting repair holes near the cracks in the concrete dam, and the drilling depth penetrates the deep cracks, and can meet the requirement that after the grouting repair pipe 4 is inserted, the grouting repair hole 401 on the side can face the crack without being blocked by the air bag 5 and unable to perform grouting repair. Then the grouting repair will be carried out. The tube 4 is inserted into the grouting repair hole, and the outer diameter of the circular ring formed by the multiple groups of air bags 5 arranged in a ring and filled with air is larger than the inner hole of the grouting repair hole. At this time, if the air bag 5 contacts the crack area, since the air bag 5 is in a compressed state at this time, it will expand into the crack. Then the pressure sensor 6 detects the pressure change and inputs the information into the computer to record the position and size of the crack until it is inserted to the bottom and then moves from bottom to top. The air bag 5 blocks the upper and lower parts of the side grouting repair hole 401 to form a relatively blocked space. Then, the crack area is grouting repaired through the side grouting repair hole 401 in this relatively blocked space.

[0057] Because a hydraulic anchor drill is used to drill the grouting repair hole, the inner diameter of the grouting repair hole is relatively smooth. Then, when the grouting repair pipe 4 is inserted into the grouting repair hole, the air bag 5 on the grouting repair pipe 4 will be subject to less friction resistance. Therefore, the pressure value in the air bag 5 is relatively stable at this time, or even does not change. Specifically, a threshold value can be set. The value within the threshold value can be considered as the friction generated during movement. This threshold value must first be moved in a smooth pipe. This pipe is a cement pipe, and the interior is punched by a punching device, and the inner wall is smooth. Then, the movement is performed to know the range of change of the air pressure in the air bag 5 during normal movement, and experimental verification is carried out many times according to different concretes to obtain balanced data as the threshold value. Finally, when in use, the fluctuation within the threshold value can be verified by a computer with the three-dimensional stereogram previously obtained by radar detection to determine whether it is a crack, and finally to choose whether to perform grouting repair later.

[0058] The material of the airbag 5 can be silicone rubber or polyurethane material, and some polytetrafluoroethylene coating can be applied on the surface to facilitate long-term use.

[0059] A better implementation method, such as Figure 5 、 Figure 6 、 Figure 8 As shown, a slide groove 402 is provided on the grouting repair pipe 4, and multiple groups of sliding rings 403 are slidably connected to the slide groove 402. The airbag 5 is installed on the sliding ring 403, and the sliding ring 403 is installed with an electromagnet 1 701 and an electromagnet 2 702. The sliding ring 403 can be fixedly connected to the grouting repair pipe 4 through the electromagnet 1 701 and the electromagnet 2 702, and the different sliding rings 403 can be moved closer to or away from each other under the action of opposite poles attracting each other and like poles repelling each other through the change of the magnetic poles between the electromagnet 1 701 and the electromagnet 2 702, so as to adjust the position of the sliding ring 403 on the grouting repair pipe 4.

[0060] By inserting the grouting repair pipe 4 into the grouting repair hole and detecting the position of the cracks, some large cracks, such as cracks in the form of long longitudinal strips that are in contact with the grouting repair hole, are found. Since these cracks are long, the pressure of the repair fluid will be dispersed during the grouting repair, and most of these cracks are subsequently connected, which makes it easy for the grouting process to cause the phenomenon of slurry bleeding due to mutual connection. At this time, the electromagnet 1 701 and the electromagnet 2 702 on the two sets of sliding rings 403 near the side grouting repair hole 401 are made to have the same magnetic pole, and then the magnetism of the electromagnet 1 701 on the upper or lower sliding ring 403 is reduced. At this time, the connection between the sliding ring 403 and the grouting repair pipe 4 will be relatively reduced and no longer so tight. At the same time, the magnetism is adjusted For opposite magnetism, at this time, through the attraction of opposite poles, this group of sliding rings 403 can move closer to the position of the side grouting repair hole 401 until they touch each other, and the remaining sliding rings 403 move closer to each other in the same way. In this way, multiple groups of sliding rings 403 can be tightly fitted, and the longitudinal length of the annularly installed airbags 5 can be increased, thereby sealing larger cracks. At this time, when grouting repair is carried out, the grouting repair liquid can be concentratedly entered through the middle and lower areas of the large cracks, and the cracks can be filled subsequently through this larger combined airbag 5. The larger combined airbag 5 is not used initially in order to detect the crack position. The smaller airbag 5 can contact the crack and change, while the larger airbag 5 is more difficult to detect the crack position.

[0061] The two groups of electromagnets are set up to reduce the interference caused by electromagnets in other positions when they are brought closer to or away from each other through magnetism. At this time, one group of electromagnets is used to stabilize its own position, and the other group is used to control the magnetic poles. Then, the electromagnets that control the magnetic poles cooperate with the electromagnets on the upper or lower sliding ring 403 to bring them closer together or move away from each other through the same magnetism.

[0062] Specifically, when detecting the position of the crack, if there is a longer crack, the lowest airbag 5 will contact the crack, and then the pressure value of the airbag 5 will change. For example, when a single small airbag 5 contacts the crack, the local pressure drops or the deformation is abnormal. For example, the pressure of the left small airbag 5 drops suddenly, and the circumferential position of the crack can be located. The crack is located at 3 o'clock on the left side of the pipe. The deformation of multiple adjacent small airbags 5 is coordinated. For example, the expansion rate of 3 consecutive small airbags 5 exceeds the threshold. The circumferential extension range of the crack can be judged. The crack surrounds the pipe 120°. At the same time, through the pressure difference of different axial airbag 5 groups, such as the pressure of the upper airbag 5 is stable and the pressure of the lower airbag 5 drops suddenly, the axial position of the crack is located, for example, 20 cm from the pipe mouth. Combined with the deformation of multiple axial airbags 5 groups, the vertical height of the crack is inverted. For example, the expansion rate of the lower airbag 5 is 15%, and the upper layer is 5%. It is inferred that the crack height is about 5 cm.

[0063] A further embodiment, such as Figure 6 、 Figure 7 As shown, an opening is provided at the bottom of the grouting repair pipe 4, a pipe bottom sealing plate 404 is threadedly connected to the opening, a bottom grouting repair hole 405 is provided on the pipe bottom sealing plate 404, and a solenoid valve is installed on the bottom grouting repair hole 405.

[0064] By setting the bottom grouting repair hole 405, when grouting and sealing the cracks above the grouting repair hole, in order to reduce the backflow of the repair liquid in the cracks caused by the hollowness of the grouting repair hole, when the grouting repair pipe 4 moves upward, the bottom solenoid valve is opened, and the grouting repair hole is filled through the bottom grouting repair hole 405. At this time, it is best to also set a solenoid valve at the side grouting repair hole 401 to avoid the retention of repair liquid in the relatively blocked space formed by the airbag 5.

[0065] like Figure 1 , such as 2, Figure 3 、 Figure 4 As shown, it is also provided with: a support frame 3, a hydraulic device 301 is fixedly connected to the support frame 3, a grouting repair pipe 4 is installed on the telescopic end of the hydraulic device 301, a mounting plate 302 is fixedly connected to the telescopic end of the hydraulic device 301, a clamping plate 303 is installed on the mounting plate 302 by bolts, and a mounting hole is provided in the middle of the mounting plate 302 and the clamping plate 303 after splicing, the grouting repair pipe 4 is installed in the mounting hole between the mounting plate 302 and the clamping plate 303, a mounting groove is provided in the mounting hole, and a mounting ring matching the mounting groove is provided on the grouting repair pipe 4.

[0066] By arranging the mounting plate 302 and the clamping plate 303 , the grouting repair pipe 4 can be quickly installed.

[0067] A better implementation method, such as Figure 7 As shown, an air nozzle 501 is installed on the airbag 5, and a sealing lip 502 is provided on the side of the airbag 5.

[0068] The provision of the air nozzle 501 facilitates the replenishment of the gas inside the airbag 5. Before use, the gas inside the airbag 5 is replenished to within a common air pressure range through an air pump.

[0069] The sealing lip 502 is used to fill the gap on the side of the airbag 5 to reduce gas leakage.

[0070] A reservoir leakage detection and repair method, used for a reservoir leakage detection and repair device, includes the following steps:

[0071] Step 1: Detect the crack locations on the reservoir dam using a radar detection device;

[0072] Step 2: Use a punching device to drill grouting repair holes near the cracks in the concrete dam. Multiple grouting repair holes are evenly arranged along the left and right sides of the cracks, and the drilling depth penetrates deep into the cracks.

[0073] Step 3: Install the support frame 3, install the grouting repair pipe 4 on the support frame 3, and connect it to the repair liquid grouting equipment;

[0074] Step 4: Slowly insert the grouting repair pipe 4 into the grouting repair hole through the hydraulic device 301 on the support frame 3, and record the position and size of the crack through the changes of the pressure sensor 6 in the airbag 5 until it is inserted to the bottom of the grouting repair hole;

[0075] Step 5: Use the hydraulic device 301 to adjust the position of the grouting repair hole 401 on the side of the grouting repair pipe 4 so that it can be aligned with the cracks located on the same plane. At this time, the airbag 5 acts as a partition. Then, the high polymer repair liquid in the repair liquid storage tank 1 is sucked out by the repair liquid grouting equipment 2 and then discharged through the side grouting repair hole 401 to perform grouting repair on the cracks.

[0076] Step 6: Adjust the grouting position through the hydraulic device 301 and perform grouting repair on the remaining cracks above;

[0077] Step 7: After the grouting repair is completed, the grouting repair hole is sealed, and the remaining grouting repair holes are repaired and sealed in turn.

[0078] The high polymer repair fluid is prepared by mixing the resin raw material of component A and the curing agent of component B;

[0079] The raw materials of the resin of component A are as follows:

[0080] Low viscosity flexible asphalt W200: 500kg,

[0081] Environmentally friendly aromatic oil for rubber: 100kg,

[0082] Rosin polyester polyol JC-380: 80kg,

[0088] 1. Add 500k low-viscosity flexible asphalt W200 and 100kg environmentally friendly rubber aromatic oil into a clean vacuum reactor, heat to 120℃, and evacuate for 2 hours to remove the moisture inside. When the moisture content reaches less than 1 / 1000, stop evacuating.

[0089] 2. Cool down to 80℃, add 80kg rosin polyester polyol JC-380 and 270kg polyphenylmethane polyisocyanate wanenate PM200, and stir thoroughly;

[0090] 3. Use a peristaltic pump to gradually add 1 kg of catalyst dibutyltin disiliconate and 49 kg of auxiliary additives, keep the temperature at 80 ° C, and then fully react for 2 hours under stirring to form the final product. Package and store under nitrogen;

[0091] Then, before grouting repair, the prepared component A resin is heated to 120° C., and then premixed with the component B curing agent in a mass ratio of 100:0.05-0.1, and then injected into the repair liquid storage tank 1.

[0092] The present invention can assist in inspecting the crack position in the grouting repair hole by disposing the airbag 5, and can also block the upper and lower spaces of the side grouting repair hole 401, so as to facilitate concentrated grouting of a portion of the cracks and reduce incomplete grouting repair caused by insufficient pressure.

[0093] At the same time, by grouting cracks one by one from bottom to top, compared with the traditional method of directly injecting repair fluid into the grouting repair hole, it can reduce the slurry bleeding phenomenon that is easy to occur during the grouting process due to the possible interconnection between multiple crack holes, thereby facilitating the repair of reservoir concrete cracks.

Step 3: Install the support frame, install the grouting repair pipe on the support frame, and connect it to the repair liquid grouting equipment; Step 4: Slowly insert the grouting repair pipe into the grouting repair hole through the hydraulic device on the support frame, and record the position and size of the crack through the changes in the pressure sensor in the airbag until it is inserted to the bottom of the grouting repair hole; Step 5: Use the hydraulic device to adjust the position of the grouting repair hole on the side of the grouting repair pipe so that it can be aligned with the lowest crack from bottom to top. At this time, the air bags on the upper and lower sides of the grouting repair hole will act as a partition to form a relatively blocked space. Then, the high polymer repair liquid in the repair liquid storage tank is sucked out through the repair liquid grouting equipment and then discharged through the side grouting repair hole to perform grouting repair on the cracks in the blocked space. Step 6: Adjust the grouting position by the hydraulic device to move the side grouting repair hole upward, and then move the side grouting repair hole in the relatively blocked space to the crack above, and then grout the crack through the side grouting repair hole. The subsequent steps are the same, and the remaining cracks above are grouted in turn; Step 7: After the grouting repair is completed, the grouting repair hole is sealed, and the remaining grouting repair holes are repaired and sealed in turn.

9. A reservoir leakage detection and repair method according to claim 8, characterized in that: The high polymer repair fluid is prepared by mixing the resin raw material of component A and the curing agent of component B; The raw materials of component A resin are as follows: Low viscosity flexible asphalt W200: 500kg, Environmentally friendly aromatic oil for rubber: 100kg, Rosin polyester polyol JC-380: 80kg, wanenate PM200: 270kg, February dibutyltin silicate: 1kg, Additives: 49kg; Component B curing agent: TMR-2; The preparation process is as follows: Add 500k low-viscosity flexible asphalt W200 and 100kg environmentally friendly rubber aromatic oil into a clean vacuum reactor, heat to 120℃, and evacuate for 2 hours to remove moisture. Stop evacuating when the moisture content reaches less than 1 / 1000. Cool down to 80℃, add 80kg rosin polyester polyol JC-380 and 270kg polyphenylmethane polyisocyanate wanenate PM200, and stir thoroughly; Use a peristaltic pump to gradually add 1 kg of catalyst dibutyltin disilicate and 49 kg of auxiliary additives, keep the temperature at 80°C, and then fully react for 2 hours under stirring to form the final product, which is then packaged and stored under nitrogen. Then, before grouting repair, heat the prepared component A resin to 120°C, premix it with component B curing agent in a mass ratio of 100:0.05-0.1, and inject it into the repair liquid storage tank.
