Description

Technical Field

[0001] This invention belongs to the technical field of new energy pumped storage power stations, specifically relating to a seepage-proof panel structure for a pumped storage panel rockfill dam. Background Technology

[0002] The geotextile panel is the main seepage prevention structure of the rockfill dam / reservoir bank in a pumped-storage power station, and a key component of the seepage prevention system. Traditionally, geotextile panels are fixedly laid on the main dam structure. The joints between adjacent panels are sealed using a filling structure. Because the panels are only fixed to the dam body, and there is a lack of effective connection and constraint design between adjacent panels, relative displacement easily occurs under external loads. This displacement may cause joint expansion, preventing the filling structure from completely sealing the gaps, leading to joint leakage, and thus jeopardizing the reliability of the overall dam seepage prevention system. Furthermore, the design scheme relying solely on the filling structure itself has limitations in its joint sealing effect, making it difficult to ensure long-term reliable seepage prevention performance.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The design of the connector, slot, socket, and positioning plug of this invention enables the fixing of adjacent geomembrane panels and reduces the possibility of relative displacement between them. Furthermore, the positioning process of the positioning plug and socket requires no manual operation, providing convenience for the connection and fixing of adjacent geomembrane panels; the injection of adhesive through the injection mechanism enhances the sealing and bonding effect, improving the stability between adjacent geomembrane panels.

[0015] 2. By setting up plug-in sockets, plug-in slots, slots, and positioning plugs, when connecting adjacent seepage-proof panels, the plug-in sockets and plug-in slots are used for plugging, and several positioning plugs on the top and bottom surfaces of the plug-in sockets are inserted into several slots on the top and bottom surfaces of the plug-in slots. This fixes the adjacent seepage-proof panels, reduces the possibility of relative displacement between adjacent seepage-proof panels, and avoids changes in the gap between adjacent seepage-proof panels. This also avoids the phenomenon that the sealing gasket cannot seal the gap between adjacent seepage-proof panels.

[0016] 3. During the process of inserting the connector into the connector slot, the pressing slope of the connector slot presses the pressure slope on the positioning plug, causing the plug to automatically retract into the groove and compress the first spring. After the connector and the connector slot are connected, the plug will be aligned with the slot. The elastic force of the first spring will cause the plug to enter the slot, thereby realizing the positioning process of the positioning plug and the slot. No manual operation is required, which provides convenience for the connection and fixation between adjacent waterproof panels.

[0017] 4. After adjacent waterproof panels are connected, in addition to the sealing gasket providing gap sealing, the plug-in seat and plug-in groove are sealed by the sealing ring. At the same time, the groove between adjacent sealing rings is filled by the injection mechanism with adhesive to enhance the sealing effect. The adhesive also improves the fixing effect between adjacent waterproof panels. Attached Figure Description

[0029] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0030] like Figure 1-10 As shown, the seepage-proof panel structure of the pumped storage rockfill dam includes a panel body 1, the top surface of which is provided with a seepage-proof layer 101; it also includes: a plug-in seat 3, which is disposed on the side of the panel body 1, and a plug-in groove 4 is provided on one side of the panel body 1 for inserting the plug-in seat 3; the top and bottom walls of the plug-in groove 4 are provided with multiple evenly distributed slots 402, and the top and bottom surfaces of the plug-in seat 3 are provided with multiple evenly distributed positioning plugs 8 for inserting into the slots 402; a sealing ring 7, the number of which is several, and the sealing ring 7 is fixedly sleeved on the plug-in seat 3; a gap is formed between each pair of adjacent sealing rings 7; an injection mechanism 6, which is used to inject adhesive into the gap, and the injection mechanism 6 is connected to a pushing mechanism 5, the input end of which is disposed on the groove wall of the plug-in groove 4.

[0031] The impermeable layer 101 is made of ultra-high toughness cement-based composite material. The adhesive is epoxy resin. Before the impermeable panel is laid, the injection mechanism 6 in the impermeable panel draws in the adhesive. When the injection mechanism 6 is not drawing in the adhesive, the first piston 607 is located on the left side of the slurry cylinder 601, and the volume of the cavity containing the adhesive is at its minimum. The external pipe is connected to the port 604, and then the pipe is inserted into the container containing the adhesive. The connecting rod 608 moves to the right, causing the first piston 607 to move to the right within the slurry cylinder 601, increasing the volume of the cavity containing the adhesive. The adhesive enters the cavity containing the adhesive through the external pipe, port 604, feed pipe 603, and first one-way valve 602, thus drawing in the adhesive. After the injection mechanism 6 draws in the adhesive, as... Figure 3-5 As shown.

[0032] like Figure 8 As shown, as a specific technical solution, the positioning plug-in 8 includes a groove 802 formed on the plug-in base 3; the groove 802 is fitted with a plug post 801 with a clearance fit, and a first spring 803 is provided in the groove 802, and the plug post 801 is elastically connected to the wall of the groove 802 through the first spring 803.

[0033] like Figure 6 and Figure 9 As shown, as a specific technical solution, the end of the insertion post 801 away from the insertion base 3 is provided with a pressure-bearing inclined surface, and the top and bottom edges of the insertion groove 4 away from the panel body 1 are provided with extrusion inclined surfaces 401 that are adapted to the pressure-bearing inclined surface.

[0034] During the installation of the waterproofing panels, when connecting adjacent panels, the connector 3 is inserted into the connector slot 4. The pressure slope 401 provides a squeezing force, causing the insert 801 to move into the groove 802 for clearance. Simultaneously, the first spring 803 is compressed. After the connector 3 and connector slot 4 are connected, the insert 801 aligns with the slot 402. The compression force of the first spring 803 then inserts the insert 801 into the slot 402 for positioning, completing the connection and fixing between adjacent waterproofing panels. After the connection is fixed, several positioning plugs 8 at the top and bottom of the connector 3 provide positioning, ensuring the connection's effectiveness.

[0035] like Figure 3-4 As shown, as a specific technical solution, the sealing ring 7 is an inflatable sealing ring, and the sealing ring 7 is connected to an inflation mechanism 9. The inflation mechanism 9 includes an air storage chamber 901 disposed inside the plug-in seat 3; the plug-in seat 3 has a hole 903 on the side away from the panel body 1 that communicates with the air storage chamber 901, a third piston 902 is fitted inside the air storage chamber 901, and a movable column 905 is fixedly connected to one side of the third piston 902; the movable column 905 passes through the hole 903 and extends to the outside of the plug-in seat 3; a second spring 904 is disposed inside the air storage chamber 901; a connecting channel 906 is connected to the end of the air storage chamber 901 away from the hole 903; a plurality of outlets 907 are disposed in the connecting channel 906 away from the air storage chamber 901, and the plurality of outlets 907 are respectively connected to a plurality of inflatable sealing rings.

[0036] When the connector 3 is not inserted into the connector slot 4, the sealing ring 7 is not inflated, and the inflation mechanism 9... Figure 4 As shown; during the insertion of the connector 3 into the connector slot 4, the sealing ring 7 enters the connector slot 4 along with the connector 3 until the end of the movable column 905 of the inflation mechanism 9 contacts the inner wall of the connector slot 4. At this time, the connector 3 is not fully inserted into the connector slot 4, but the sealing ring 7 has fully entered the connector slot 4. Continuing to insert the connector 3, the inner wall of the connector slot 4 acts as a barrier, causing the movable column 905 to move into the air storage chamber 901. The movable column 905 drives the third piston 902 to compress the gas in the air storage chamber 901 and compress the second spring 904. The gas in the air storage chamber 901 is transported through the connecting channel 906 and then enters all the sealing rings 7 through the outlet 907 of the connecting channel 906, inflating the sealing rings 7 and improving their fit with the wall of the connector slot 4, thus improving the sealing performance. After the above operation, a groove is formed between every two adjacent sealing rings 7.

[0037] like Figure 3 , Figure 4 , Figure 5 as well as Figure 10As shown, as a specific technical solution, the injection mechanism 6 is disposed inside the panel body 1; the injection mechanism 6 includes a slurry cylinder 601 fixedly installed inside the panel body 1 and an air extraction part; a first piston 607 is connected to the inside of the slurry cylinder 601, a connecting rod 608 is fixedly connected to one side of the first piston 607, and the connecting rod 608 passes through a first through hole opened on one side of the slurry cylinder 601, and the other side of the first piston 607 and the inner wall of the slurry cylinder 601 form a cavity for holding adhesive, a second one-way valve 605 is provided on the side of the slurry cylinder 601 away from the connecting rod 608, the second one-way valve 605 is connected to a discharge pipe 606, and a plurality of discharge ports 6061 are provided on the discharge pipe 606 away from the second one-way valve 605, and the plurality of discharge ports 6061 are respectively connected to the bottom of a plurality of slots. A first one-way valve 602 is provided on the side of the slurry cylinder 601 away from the connecting rod 608. The first one-way valve 602 is connected to a feed pipe 603, which is connected to a port 604 located at the bottom of the panel body 1. The air extraction unit includes an air extraction cylinder 609 fixedly installed inside the panel body 1; a second piston 610 is connected inside the air extraction cylinder 609, one side of the second piston 610 is fixedly connected to the end of the connecting rod 608 away from the first piston 607, a second through hole is opened on one side of the air extraction cylinder 609 for the connecting rod 608 to pass through, the side of the first piston 607 away from the connecting rod 608 and the inner wall of the air extraction cylinder 609 form an air cavity, an interface 611 is installed on the side of the air extraction cylinder 609 away from the connecting rod 608, the interface 611 is connected to an air extraction pipe 612, a plurality of air extraction ports 6121 are provided at the end of the air extraction pipe 612 away from the interface 611, a plurality of air holes 301 are opened on the top surface of the plug-in seat 3, the plurality of air holes 301 are respectively connected to the top of a plurality of slots, and the bottom ends of the plurality of air holes 301 are respectively connected to the plurality of air extraction ports 6121. The panel body 1 has a movable groove 102 inside; the movable groove 102 provides space for the movement of the movable rod 501 and the connecting rod 608.

[0038] To improve the connection effect between adjacent waterproof panels, adhesive is injected into the slots via injection mechanism 6 to bond and reinforce the insertion seat 3 and insertion slot 4. Specifically, by driving connecting rod 608 to move to the left, connecting rod 608 drives first piston 607 to push the adhesive in the extrusion chamber, so that the adhesive is transported through discharge pipe 606, and then flows into the bottom of multiple slots through multiple discharge ports 6061 on discharge pipe 606 for adhesive injection. At the same time, connecting rod 608 drives second piston 610 to move to the left, so that the volume of the air chamber in air extraction cylinder 609 increases, and air is extracted. The gas in the slot enters the air chamber through the air hole 301 at the top, air extraction port 6121, air extraction pipe 612, and interface 611, so that the gas in the slot is discharged while the adhesive is injected into the slot, which facilitates better filling of the slot with adhesive. The adhesive is injected from below the slot, and the air extraction is performed from above the slot.

[0039] After the adhesive is filled and cured, the insertion groove 4 and the insertion seat 3 are bonded together, which improves the bonding effect between the insertion groove 4 and the insertion seat 3. At the same time, the filling groove, together with the inflated sealing ring 7, improves the sealing effect between the insertion groove 4 and the insertion seat 3, and strengthens the sealing function.

[0040] like Figure 1-2 As shown, as a specific technical solution, a sealing gasket 2 is attached to one end of the panel body 1 where the plug-in seat 3 is located, and the sealing gasket 2 is L-shaped.

[0041] After adjacent waterproof panels are connected, a sealing gasket 2 is clamped between the two waterproof panels to fill the gap between the adjacent waterproof panels, provide a seal, and play a role in preventing seepage.

[0042] like Figure 6-7As shown, as a specific technical solution, the pushing mechanism 5 includes a strip-shaped shell 502; a groove is formed on the inner side wall of the insertion groove 4, the strip-shaped shell 502 is fixedly fitted into the groove, a slider 503 is slidably installed inside the strip-shaped shell 502, a movable rod 501 is fixedly connected to the side of the slider 503 away from the insertion groove 4, and the end of the movable rod 501 away from the slider 503 is fixedly connected to the connecting rod 608; the side of the slider 503 away from the movable rod 501 is rotatably connected to... A threaded post 504 is provided, with a square groove in the middle of the threaded post 504. A square rod 507 is connected to the square groove with clearance fitting. A rotating shaft 505 is fixed to one end of the square rod 507. The rotating shaft 505 is rotatably connected to the end of the strip-shaped shell 502 near the insertion slot 4. A tightening head 506 is fixed to the end of the rotating shaft 505 away from the square rod 507. A fixing nut 508 is fixed inside the strip-shaped shell 502, and the threaded post 504 is threadedly connected to the fixing nut 508. The tightening head 506 has a hexagonal groove for inserting an internal hex wrench, which allows the head 506 to be rotated. The pushing mechanism 5 is used to drive the connecting rod 608 to move. At the same time, the pushing mechanism 5 is hidden inside the seepage-proof panel. Its operating position, namely the turning head 506, is located in the insertion groove 4. After the pushing mechanism 5 of one seepage-proof panel completes its operation, its insertion groove 4 is inserted through the insertion seat 3 of other seepage-proof panels to complete the concealment.

[0043] The operation of the driving mechanism 5 is as follows: by rotating the screw head 506 in the forward and reverse directions, the rotating shaft 505 drives the square rod 507 to rotate, the square rod 507 drives the threaded column 504 to rotate, and the threaded column 504 and the fixed nut 508 are screwed together, so that the threaded column 504 drives the slider 503 to slide left or right in the strip shell 502. The slider 503 drives the connecting rod 608 to move left and right through the movable rod 501, providing drive for the injection mechanism 6.

[0044] The square rod 507 and the square groove can slide, which is used to drive the slider 503 to move left and right with the threaded column 504. Before and after moving left and right, the square rod 507 and the square groove will not separate and will always maintain a clearance fit connection.
