A first right arc plate 104 is fixedly connected to one side of the first right arc plate 104. A first right hook 105 is fixedly connected to the first steel sheet pile body 101. The structure of the first steel sheet pile body 101 is a ladder structure. The first steel sheet pile body 101 can be used to achieve sealing. The first left arc plate 102 can cooperate with the first right arc plate 104 to form a complete space for installing a water-stop curtain. The first left hook 103 and the first right hook 105 can be engaged with each other. On the one hand, it provides fixation of adjacent first steel sheet pile bodies 101. On the other hand, it can form a labyrinth seal, so that the cement used to serve as a water-stop curtain can fully fill the gap between adjacent first steel sheet pile bodies 101, effectively block the water flow, and improve the water blocking effect.
[0040] See also Figure 1 A plurality of first steel sheet pile assemblies 1 are provided, and two adjacent first steel sheet pile assemblies 1 are engaged with each other through a first left hook 103 and a first right hook 105. The first left hook 103 and the first right hook 105 can limit the gap and verticality error between adjacent first steel sheet pile bodies 101, prevent excessive installation errors, ensure the correct alignment of each steel sheet pile, and form a labyrinth seal, which increases the difficulty of water flow passing through the steel sheet piles, thereby improving the overall sealing effect, allowing multiple steel sheet pile assemblies to be closely connected to each other, thereby enhancing the stability and durability of the overall structure.
[0041] The implementation principle of the utility model is: first, a first steel sheet pile body 101 is driven in, and then another first steel sheet pile body 101 is driven in, so that the adjacent first left hook 103 and the first right hook 105 are engaged with each other, so that the first left arc plate 102 and the first right arc plate 104 form a space with each other, and then the soil inside the space is taken out, and cement is filled in the space, so that a water-stop curtain can be formed after the cement solidifies.
