[0027] In order to facilitate the installation and adjustment of the movable connecting plate 1013 and the sealing pressure plate 1012 for reinforcement and sealing through the fixed connection assembly, in this embodiment, preferably, the fixed connection assembly includes a rear fixing plate 1011 that is fixedly installed at the bottom of the rear surface of the seepage-proof wall panel 101 by bolts, and the rear fixing plate 1011 matches the structure of the bottom of the rear surface of the seepage-proof wall panel 101.

[0028] In order to facilitate the reinforcement and sealing of the bottom end of the seepage-proof wall panel 101 through the reinforcement and sealing assembly, in this embodiment, preferably, the reinforcement and sealing assembly includes a movable connecting plate 1013 disposed inside the rear fixed plate 1011. The bottom end of the movable connecting plate 1013 is fixedly installed with a sealing pressure plate 1012 by screws.

When the adjusting threaded rod 1017 rotates, it can drive the movable connecting plate 1013 and the sealing pressure plate 1012 downward through the uniformly stressed mounting plate 1016, so as to facilitate the downward movement of the sealing pressure plate 1012 to strengthen the sealing installation.

[0031] The reinforcement installation mechanism includes a reinforcement installation component located at the bottom of the pile 103. A support reinforcement component is provided at the connection between the surface of the mounting ring 106 and the rear surface of the seepage-proof wall panel 101. The reinforcement installation mechanism can strengthen and fix the pile 103 during installation and use, thereby strengthening and fixing the main body 100 of the dam foundation seepage-proof structure and reinforcing the seepage prevention treatment.

[0032] To facilitate the reinforcement and fixing of the pile 103 using the reinforcement installation assembly, in this embodiment, preferably, the reinforcement installation assembly includes a fixing ring 1031 fitted onto the bottom end of the outer surface of the pile 103. Fixing bolts 1032 are equidistantly arranged on the surface of the fixing ring 1031. Three reinforcement columns 1033 are welded and fixed to the surface of the fixing ring 1031. A limiting reinforcement ring 1034 is provided at the bottom end of the reinforcement column 1033. The reinforcement column 1033 and the limiting reinforcement ring 1034 can be cast at the installation position, and the pile 103 can be inserted into the ground through the fixing ring 1031 and fixed again, thereby strengthening and fixing the pile 103, and making the dam foundation closed seepage prevention structure main body 100 stronger and more secure for use.

[0033] To facilitate the reinforcement installation at the midpoint between the pile 103 and the rear surface of the seepage-proof wall panel 101 using a support and reinforcement assembly, in this embodiment, preferably, the support and reinforcement assembly includes a reinforcement support plate 1035 welded and fixed to the surface of the mounting ring 106 located on both sides of the reinforcement rod 105. An auxiliary mounting plate 1036 is provided at the end of the reinforcement support plate 1035, and the surface of the auxiliary mounting plate 1036 is fixed to the rear surface of the seepage-proof wall panel 101 by mounting bolts. After the reinforcement rod 105 is fixedly installed, the midpoint between the pile 103 and the rear surface of the seepage-proof wall panel 101 can be reinforced again using the reinforcement support plate 1035 and the auxiliary mounting plate 1036, facilitating the use of reinforcement support.

[0034] The working principle and usage process of this utility model: Before use, the pile column 103 is first fixedly installed on one side of the installation location. The two anti-seepage wall panels 101 are sealed and installed by the sealing groove 102 and the sealing plate 104. Then, concrete is poured at the connection to strengthen the seal. At this time, the installation ring 106 is fitted onto the end surface of the pile column 103 and fixed. The end of the reinforcing rod 105 is closed at the connection of the rear surface of the two anti-seepage wall panels 101, thereby reinforcing the rear surface of the two anti-seepage wall panels 101 with the reinforcing rod 105. This makes the main body 100 of the dam foundation closed anti-seepage structure fixedly installed at the dam foundation of the reservoir reinforcement project for closed anti-seepage use.

[0035] Before installation, the reinforcing column 1033 and the limiting reinforcing ring 1034 can be first installed underground at the side of the pile column 103 by pouring concrete. After the reinforcing column 1033 is fixed, the pile column 103 is inserted into the ground through the inside of the fixing ring 1031. The fixing bolt 1032 is rotated to fix the fixing ring 1031 and the reinforcing column 1033, thereby reinforcing the reinforcing column 1033. After the installation ring 106 is fitted onto the outer surface of the pile column 103 and fixed, the connection between the reinforcing rod 105 and the seepage-proof wall panel 101 is installed. The auxiliary installation plate 1036 at the end connection of the reinforcing support plate 1035 is then contacted with the rear surface of the seepage-proof wall panel 101 and fixed by the installation bolt. This strengthens and fixes both the anti-seepage wall panel 101 and the pile column 103, making the main body 100 of the dam foundation closed anti-seepage structure reinforced and installed for anti-seepage purposes, and improving the reinforcement and fixation of the main body 100 of the dam foundation closed anti-seepage structure in the reservoir reinforcement project.

[0036] Finally, when the main body 100 of the dam foundation sealing and seepage prevention structure is used after installation, the wrench is once again engaged at the end of the adjusting threaded rod 1017 to screw the adjusting threaded rod 1017 inward for adjustment. When the adjusting threaded rod 1017 is screwed in, the moving connecting plate 1013 is driven to move downward with uniform force through the uniformly stressed mounting plate 1016. As the moving connecting plate 1013 moves downward, it drives the limiting slider 1015 to slide and stabilize within the limiting groove 1014 until the moving connecting plate 1013 is stabilized. The moving mechanism causes the sealing plate 1012 to move downwards, pressing it tightly against the bottom of the dam foundation. Simultaneously, the side of the sealing plate 1012 presses tightly against the surface of the anti-seepage wall panel 101, and the ends of the two sealing plates 1012 are in tight contact. This facilitates the reinforcement of the bottom of the dam foundation's anti-seepage structure 100 after installation, ensuring a more secure and sealed seal. This enhances the reinforcement, sealing, and anti-seepage effect of the dam foundation's anti-seepage structure 100 on the bottom of the anti-seepage wall panel 101 in the reservoir reinforcement project.
