Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and in particular to a water-stopping and seepage-proof structure for water conservancy engineering construction. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water is an essential and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water volume. Dams are a type of water conservancy project. After the existing dams are poured and constructed, in order to avoid the impact of thermal expansion and contraction on the dams, evenly distributed expansion joints are opened on their surface. Usually, they are opened by cutting. However, during the cutting process, friction and vibration can cause small cracks to appear inside the expansion joints. These cracks are prone to water seepage.

[0003] A search revealed a Chinese patent (publication number CN214301580U) disclosing a water-stopping and seepage-proofing structure for water conservancy engineering construction. This patented technology utilizes a top rod, locking nut, water-stop plate, water-blocking block, push block, clamping plate, spring, first sealing gasket, and second sealing gasket. The water-blocking block is embedded in the water-stopping hole. Rotating the locking nut moves the top rod upwards, which in turn moves the two clamping plates via the push block, thus securing the water-blocking block in the water-stopping hole. Further tightening of the locking nut allows the water-stopping plate to block the water-stopping hole. While this method is applicable to water-stopping holes, it can also be applied to sealing cracks in expansion joints. However, this method is relatively cumbersome to install, and the high moisture content around dams can easily cause the nuts to corrode, making later disassembly inconvenient. Therefore, those skilled in the art have provided a water-stopping and seepage-proofing structure for water conservancy engineering construction to solve the problems mentioned in the background art. Summary of the Invention

[0014] In one embodiment, a fixing block located inside the trigger cavity is fixedly connected to the top of the adjusting block, and a limit spring is fixedly connected to the surface of the fixing block, with the other end of the limit spring fixedly connected to the inner wall of the trigger cavity.

[0015] In one embodiment, the surface of the sliding column is provided with uniformly distributed limiting grooves, and the top of the sliding column is provided with a notch that communicates with the limiting grooves, and the notch and the adjusting block are distributed alternately.

[0016] In one embodiment, the auxiliary structure includes a plurality of inserts fixedly connected to one of the connecting plates on the side away from the mounting plate.

The other connecting plate is provided with inserts that are staggered with the inserts on the side away from the mounting plate, and the surface of the inserts is fixedly connected with a sliding block that is slidably connected to the inner wall of the adjacent sliding groove.

[0036] The following is combined with Figures 1-8 This invention describes a water-stopping and seepage-proof structure for hydraulic engineering construction.

[0037] like Figures 1-8 As shown, in one embodiment, a water-stopping and seepage-proof structure for hydraulic engineering construction includes:

[0038] There are two connecting plates 1, and each of the two connecting plates 1 is fixedly connected to a mounting plate 102 on the opposite side. The surface of the mounting plate 102 is provided with a through hole 103.

[0039] Positioning structure 2 is disposed at the bottom of mounting plate 102, and positioning structure 2 is coaxially disposed with through hole 103;

[0040] Auxiliary structure 3, wherein the auxiliary structure 3 is disposed between the two connecting plates 1;

[0041] The positioning structure 2 includes a mounting post 201 fixedly connected to the bottom of the mounting plate 102. The mounting post 201 is coaxially arranged with the through hole 103, and the diameter of the mounting post 201 is larger than the diameter of the through hole 103. A trigger cavity is opened inside the mounting post 201, and a sliding post 206 is slidably connected to the inner wall of the trigger cavity.

[0042] During installation, the expansion joint that needs to be covered is located between the two connecting plates 1 and is covered and sealed by the auxiliary structure 3 to reduce water from entering the expansion joint and causing water seepage.

[0043] like Figures 1-6 As shown, the bottom of the sliding column 206 is provided with an installation groove, and a first spring 209 is fixedly connected to the inner wall of the installation groove. The lower end of the first spring 209 passes through the installation groove and is fixedly connected to the inner bottom wall of the trigger cavity. A trigger rod 207 is fixedly connected to the bottom of the sliding column 206, and the lower end of the trigger rod 207 passes through the installation column 201 and is fixedly connected to a trigger block 208.

[0044] The upper end of the sliding column 206 is fixedly connected to a connecting rod 211. The upper end of the connecting rod 211 passes through the mounting column 201 and is fixedly connected to an indicator block 212. The indicator block 212 is located inside the through hole 103, and a groove 213 is provided on the top of the indicator block 212.

[0045] The inner wall of the trigger cavity is slidably connected with evenly distributed adjustment blocks 203. The other end of the adjustment block 203 passes through the mounting post 201 and is fixedly connected with a resistance increasing block 202. The resistance increasing block 202 is a rubber material component.

[0046] The bottom of the adjusting block 203, which is away from the resistance increasing block 202, has a wedge surface, and the setting height of the adjusting block 203 is higher than the top surface height of the sliding column 206.

[0047] The top of the adjusting block 203 is fixedly connected to a fixing block 205 located inside the trigger cavity. A limiting spring 204 is fixedly connected to the surface of the fixing block 205, and the other end of the limiting spring 204 is fixedly connected to the inner wall of the trigger cavity.

[0048] The surface of the sliding column 206 is provided with uniformly distributed limiting grooves 210, and the top of the sliding column 206 is provided with a notch 214 that communicates with the limiting grooves 210, and the notch 214 and the adjusting block 203 are distributed alternately.

[0049] During installation, drilling holes along the expansion joint openings aligns the mounting post 201 with its position. This allows the mounting post 201 to be inserted into the drilled holes. During installation, the trigger block 208 contacts the inner bottom wall of the mounting hole first, and continued pressure causes it to be blocked by the inner wall, thus inserting the trigger rod 207 into the trigger cavity. This process simultaneously moves the sliding post 206 upwards, causing the top of the sliding post 206 to press against the bottom wedge surface of the adjusting block 203, causing it to extend from the mounting post 201 and compressing the limiting spring 204. This process also causes the resistance-increasing block 202 to conform to the inner wall of the mounting hole. To enhance positioning and prevent loosening, the resistance block 202, being made of rubber, deforms when blocked by the inner wall of the mounting hole. When the limiting groove 210 moves to the adjusting block 203, the adjusting block 203 is reset under the action of the limiting spring 204, partially inserting into the limiting groove 210. The resistance block 202, under its own elastic deformation, resets to maintain a proper fit with the mounting hole, enhancing positioning. Simultaneously, because the top of the adjusting block 203 is limited by the limiting groove 210, it prevents the sliding column 206 from moving downwards, thus maintaining the position of the sliding column 206 and keeping the adjusting block 203 in place via the limiting groove 210. This simplifies installation.

[0050] During the upward movement of the sliding column 206, the connecting rod 211 can be moved upward synchronously and the indicator block 212 can be moved along the inner wall of the through hole 103. During the installation process, the construction personnel can judge whether the installation is in place by observing whether the indicator block 212 is parallel to the top surface of the mounting plate 102. After the installation is in place, the top surface of the indicator block 212 is parallel to the top surface of the mounting plate 102.

[0051] During disassembly, a flathead screwdriver can be inserted into the groove 213 and used to rotate the groove 213 and the indicator block 212, which can drive the connecting rod 211 to rotate synchronously. During this process, the position of the sliding column 206 is adjusted so that the notch 214 moves to the adjusting block 203. At this time, the sliding column 206 can be moved down under the action of the first spring 209, thereby releasing the limiting effect on the adjusting block 203. The adjusting block 203 can then be reset under the action of the limiting spring 204, so as to facilitate the disassembly of the device.

[0052] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the auxiliary structure 3 includes several insert blocks 301 fixedly connected to one of the connecting plates 1 on the side away from the mounting plate 102. The surface of the insert block 301 is provided with a sliding groove 302. The other connecting plate 1 on the side away from the mounting plate 102 is provided with insert plates 303 that are staggered with the insert blocks 301. The surface of the insert plate 303 is fixedly connected with a sliding block that is slidably connected to the inner wall of the adjacent sliding groove 302.

[0053] One of the connecting plates 1 has uniformly distributed sealing airbags 305 embedded in its surface. One side of the sealing airbag 305 is in contact with the surface of the insert block 301. The inner wall of the connecting plate 1 has uniformly distributed gas storage chambers 306. The gas storage chambers 306 are filled with inert gas. The surface of the sealing airbag 305 is connected to a conduit 308. The other end of the conduit 308 is connected to the adjacent gas storage chamber 306.

[0054] A sliding plate 304 is slidably connected to the inner wall of the gas storage chamber 306. A fixing rod 309 is fixedly connected to one side of the sliding plate 304. The other end of the fixing rod 309 passes through the connecting plate 1 and is fixedly connected to the surface of the insert block 301. A second spring 307 is sleeved on the surface of the fixing rod 309. One end of the second spring 307 is fixedly connected to the surface of the sliding plate 304, and the other end of the second spring 307 is fixedly connected to the inner wall of the gas storage chamber 306.

[0055] Since it is covering the expansion joint of the dam, in order to reduce the impact of thermal expansion and contraction on the dam, the expansion joint itself can cause the two connecting plates 1 to move away from each other when it deforms. In this process, it can cause the insert plate 303 to separate from the insert block 301. During the movement of the insert block 301, it can cause the fixing rod 309 to move synchronously, thereby causing the sliding plate 304 to compress the inert gas stored in the air storage chamber 306. The compressed inert gas can be injected into the interior of the sealing airbag 305 through the conduit 308. In this process, the sealing airbag 305 can be inflated to keep it in close contact with the insert block 301, maintain a good sealing effect, reduce the possibility of water entering the expansion joint and causing water seepage, and effectively improve the water-stopping and seepage prevention effect.

[0056] Working principle: During installation, drilling installation holes along the expansion joint opening position, aligning them with the position of the mounting post 201, and placing the expansion joint to be covered between the two connecting plates 1, inserting the mounting post 201 into the drilled installation hole, allows the trigger block 208 to contact the inner bottom wall of the installation hole first, and continues to apply pressure until it is blocked by the inner wall of the installation hole, causing the trigger rod 207 to insert into the trigger cavity. Through the cooperation of the limiting groove 210, the limiting spring 204, and the adjusting block 203, the adjusting block 203 unfolds, causing the resistance increasing block 202 to fit against the inner wall of the installation hole, enhancing the positioning effect and preventing loosening. The installation method is simple. During the installation process, the construction personnel judge whether the indicator block 212 is parallel to the top surface of the mounting plate 102. Whether it is installed in place or not, after installation, the top surface of the indicator block 212 is parallel to the top surface of the mounting plate 102. During later disassembly and maintenance, a flathead screwdriver is inserted into the inside of the groove 213, and the flathead screwdriver is used to drive the groove 213 to rotate the indicator block 212 so that it can drive the connecting rod 211 to rotate synchronously. During this process, the position of the sliding column 206 is adjusted so that the notch 214 moves to the adjusting block 203. At this time, under the action of the first spring 209, the sliding column 206 can be driven to move down, thereby releasing the effect of limiting the adjusting block 203. The adjusting block 203 can then be reset under the action of the limiting spring 204, so as to facilitate the disassembly of the device. After installation, the expansion joint can be blocked by the auxiliary structure 3 to reduce the situation of water entering the expansion joint and causing water seepage.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
