[0002] Currently, there are a large number of dilapidated reservoirs. Due to their age, the dam body and foundation have serious seepage, making them unable to perform their normal functions. The technologies used for dam seepage prevention now include curtain grouting, concrete anti-seepage panels, and high-pressure jet grouting. Among these, concrete anti-seepage panels are frequently used due to their lower material cost.

[0003] According to Chinese Patent Application No. CN202122938539.X, a concrete panel structure for dam seepage prevention is disclosed, relating to the field of dam seepage prevention technology. This utility model includes a concrete panel body, with a splicing component on one side and a splicing groove on the other side. The splicing component and the splicing groove are used to splice multiple concrete panel bodies. The top and bottom of the splicing component are equipped with locking components. This utility model, through the structural design of the splicing component, allows for guidance during panel use, making pouring and splicing more convenient. It also provides greater stability after pouring and splicing, ensuring seepage prevention. The locking component design facilitates easier panel positioning and splicing without repeated alignment, thus not affecting construction progress. Although tension springs, locking blocks, T-shaped sliders, and guide limiting blocks can be used to splice two concrete panels, these methods are complex, inconvenient for prefabrication and splicing, and leave internal gaps at the splice points, making them prone to damage and less practical.

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a seepage-proof concrete panel structure for a water conservancy dam, comprising a concrete panel body 1. One side of the concrete panel body 1 is connected to the other side of another concrete panel body 1 via a splicing and connecting component 2. The splicing and connecting component 2 includes an L-shaped first splicing plate 201 disposed on one side of the concrete panel body 1, and a second splicing plate 202 disposed on the other side of the concrete panel body 1 to match and splice with the first splicing plate 201 on the other concrete panel body 1. The outer end of the first splicing plate 201 is provided with a plurality of equidistantly distributed limiting splicing grooves 203, and the second splicing plate 202 is provided with a plurality of limiting splicing blocks 204 that match the limiting splicing grooves 203. When splicing the two concrete panel bodies 1, the first splicing plate 201 of one concrete panel body 1 is matched and spliced ​​with the second splicing plate 202 of the other concrete panel body 1. At the same time, the limiting splicing blocks 204 match the limiting splicing grooves 203, which facilitates the splicing of the two concrete panel bodies 1.

[0029] Specifically, such as Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, after the first splicing plate 201 and the second splicing plate 202 are spliced ​​together, the first splicing plate 201 and the second splicing plate 202 are connected by a limiting connection component 205. The limiting connection component 205 includes a first connecting hole 2051 opened on the first splicing plate 201 and passing through the limiting splicing groove 203. A second connecting hole 2052 corresponding to the first connecting hole 2051 is opened on the limiting splicing block 204. When the limiting splicing block 204 matches and engages with the limiting splicing groove 203, the multiple first connecting holes 2051 and the multiple second connecting holes 2052 are in a straight line. The cross-section of the first connecting hole 2051 and the second connecting hole 2052 is rectangular and the dimensions are equal. A limiting connecting rod 2053 matching the first connecting hole 2051 and the second connecting hole 2052 passes through the first connecting hole 2051 and the second connecting hole 2052. The first splicing plate The top of 201 is provided with a limiting groove 2054 located at the first connecting hole 2051, and the top of the limiting connecting rod 2053 is provided with a positioning block 2055 that matches the limiting groove 2054. After the first splicing plate 201 and the second splicing plate 202 are matched and snapped together, the multiple first connecting holes 2051 and the multiple second connecting holes 2052 are in a straight line. When the limiting connecting rod 2053 is inserted into the first connecting hole 2051 and the second connecting hole 2052, the first splicing plate 201 and the second splicing plate 202 can be limited, avoiding the separation of the first splicing plate 201 and the second splicing plate 202. This improves the stability of the two concrete panel bodies 1 after splicing, enhances the integrity and seismic adaptability of the anti-seepage concrete panel structure of the water conservancy dam, and has the characteristics of easy prefabrication and easy splicing, making it more practical. There will be no gaps inside after splicing, avoiding the situation of the splice being crushed.

[0030] Specifically, such as Figure 2 As shown, a copper waterstop 3 is provided at the connection between the first splicing plate 201 and the second splicing plate 202, and SR plastic filler 4 is filled on the outside of the connection between the first splicing plate 201 and the second splicing plate 202 to form a double-layer waterstop, which has better anti-seepage performance.

[0031] Specifically, such as Figure 3 and Figure 5 As shown, a limiting groove 6 is provided on one side of the concrete panel body 1, and a limiting strip 7 is provided on one side of the copper waterstop 3 to match and engage with the limiting groove 6. The limiting groove 6 and the limiting strip 7 engage with each other, which improves the stability of the copper waterstop 3.

[0032] Specifically, such as Figure 7 As shown, the surface of the concrete panel body 1 is sprayed with an ultra-high toughness cement-based composite material layer 5. The ultra-high toughness cement-based composite material layer 5 has a strong deformation capacity and a crack-free dispersion characteristic, which improves impermeability and durability.

[0033] During operation, this type of anti-seepage concrete panel structure for water conservancy dams, when splicing two concrete panel bodies 1, ensures that the first splicing plate 201 of one concrete panel body 1 matches and splices with the second splicing plate 202 of the other concrete panel body 1. Simultaneously, the limiting splicing block 204 matches the limiting splicing groove 203, facilitating the splicing of the two concrete panel bodies 1. After the first splicing plate 201 and the second splicing plate 202 are matched and engaged, the multiple first connecting holes 2051 and the multiple second connecting holes 2052 are aligned in a straight line. The limiting connecting rod 2053 is inserted into the first connecting hole 2051 and the second connecting hole 2052 to limit the first splicing plate 201 and the second splicing plate 202, preventing the separation of the first splicing plate 201 and the second splicing plate 202. This improves the stability of the two concrete panel bodies 1 after splicing, enhances the integrity and seismic adaptability of the anti-seepage concrete panel structure of the water conservancy dam, and has the characteristics of easy prefabrication and splicing, making it more practical. There will be no gaps inside after splicing, avoiding the situation of the splice being crushed.
