[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Please see Figure 1-8 A U-shaped prestressed concrete sheet pile anti-scour wall structure includes: precast sheet piles 1, with protruding blocks 2 on the outer wall of the precast sheet piles 1, square grooves 3 on the outer wall of the precast sheet piles 1, circular grooves 4 on the inner wall of the protruding blocks 2, insert rods 5 sleeved on the inner wall of the square grooves 3, butt joint grooves 6 on the inner wall of the precast sheet piles 1, screw holes 7 on the inner wall of the precast sheet piles 1, and triangular support frames 8 overlapping the inner wall of the precast sheet piles 1. Triangular filling grooves 9 are formed on the inner wall of the triangular support frames 8. A triangular fixing block 10 is fitted onto the inner wall of the corner filling groove 9. An installation piece 11 is connected to the outer wall of the triangular support frame 8. A threaded nail 12 is provided on the inner wall of the installation piece 11. An installation round hole 13 is provided on the outer wall of the precast sheet pile 1. A metal plate 14 is provided on the outer wall of the precast sheet pile 1. A metal block 15 is connected to the outer wall of the metal plate 14. A filling block 16 is fitted onto the inner wall of the metal block 15. An installation nail 17 is fitted onto the inner wall of the metal block 15. A connecting nail 18 is fitted onto the inner wall of the metal plate 14.
[0020] Among them, the protruding block 2 is set on one side of the precast sheet pile 1, and the middle of the protruding block 2 is provided with a fault. The protruding block 2 on the device is set on the right side of the precast sheet pile 1, so that the protruding block 2 on the device appears on the right side of the precast sheet pile 1 in a protruding manner, and the middle part is provided with a fault, so that the protruding block 2 on the device can be connected with the precast sheet pile 1.
[0021] The precast sheet pile 1 has a square groove 3 on its left inner wall, and a circular groove 4 is opened on the inner wall of the square groove 3 and the protruding block 2. The square groove 3 on the device is opened on the left side of the precast sheet pile 1 in a recessed form, so that the circular groove 4 on the device penetrates the square groove 3 and the protruding block 2 with the same diameter. This allows the precast sheet pile 1 on the device to make a complete fit and connection when it uses its own left and right sides to connect with the left and right sides of another precast sheet pile 1.
[0022] The inner diameter of the circular groove 4 is matched with the outer diameter of the plug rod 5. The protruding block 2 and the circular groove 4 are fitted onto the plug rod 5. The precast sheet pile 1 and another precast sheet pile 1 on the device are connected to the inner cavity of the square groove 3 by the protruding block 2. This allows the plug rod 5 on the device to pass through the protruding block 2 on the side of one precast sheet pile 1 and the square groove 3 on the side of another precast sheet pile 1 through the circular groove 4, so that the precast sheet pile 1 and the other precast sheet pile 1 on the device can be snapped together.
[0023] Among them, the two sides of the triangular support frame 8 correspond to the position of the docking groove 6, and the triangular support frame 8 is set in a triangular shape. Multiple triangular support frames 8 on the device are installed corresponding to the points of the docking groove 6, so that the triangular support frame 8 on the device plays an inverted triangular support role on the inner wall of the precast sheet pile 1 with its own triangular shape, thereby supporting the two sides and the center point of the inner wall of the precast sheet pile 1 on the device by the triangular support frame 8.
[0024] The triangular support frame 8 is made of metal, and the triangular fixing block 10 is cast in the inner cavity of the triangular filling groove 9. Due to the characteristics of the metal material used in the triangular support frame 8, the triangular support frame 8 can pre-apply stress in the component in the opposite direction of the load stress. The triangular support frame 8 is filled with the triangular fixing block 10 in the triangular filling groove 9, so that the triangular support frame 8 can save metal material and then use the triangular fixing block 10 for filling.
[0025] The mounting plate 11 is set on both sides of the triangular support frame 8, and the threaded nail 12 extends through the inner wall of the mounting plate 11 into the inner wall of the precast sheet pile 1. The mounting plate 11 on the device is set on the side of the triangular support frame 8 close to the precast sheet pile 1, so that the threaded nail 12 on the device passes through the inner wall of the mounting plate 11 and enters the inner wall of the precast sheet pile 1, and is threadedly connected to the position of the screw hole 7, so that the triangular support frame 8 on the device can be installed on the inner wall of the precast sheet pile 1 by means of the connection.
[0026] The metal plate 14 and the metal block 15 are at right angles, and the mounting nail 17 passes through the inner wall of the metal plate 14 and the metal block 15 and enters the outer wall of the precast sheet pile 1. The metal plate 14 and the metal block 15 on the device are erected on the outer wall of the precast sheet pile 1 at right angles, so that the metal plate 14 and the metal block 15 on the device form an external prestressed structure on the outside of the precast sheet pile 1. The side of the metal plate 14 and the metal block 15 closest to the precast sheet pile 1 are fixedly connected by the mounting nail 17, so that the metal block 15 and the metal plate 14 on the device are installed as a whole on the outside of the precast sheet pile 1.
[0027] The inner wall of the metal block 15 is matched with the outer wall of the filling block 16 in size, and the filling block 16 is made of concrete. A rectangular groove is provided on the inner wall of the metal block 15, so that concrete is filled into the groove of the metal block 15 before installation, thereby completing the prefabrication of the metal block 15, and then the installation is carried out to implement the external prestressing effect.
[0028] The inner wall of the metal plate 14 is fitted with a connecting nail 18, and the outer wall of the connecting nail 18 is threaded with a nut. The metal plate 14 is installed on the outer side of the precast sheet pile 1 on the device, so that the outer wall of the precast sheet pile 1 on the other side of the precast sheet pile 1 is also fitted with a metal plate 14. The connecting nail 18 passes through the outer walls of the two metal plates 14 and completes the threaded connection. Thus, when the two precast sheet piles 1 and the metal plate 14 are in contact with each other, the connecting nail 18 and the nut are used to make the threaded connection.
[0029] The working principle involves first setting up precast sheet piles 1, triangular support frames 8, metal plates 14, and metal blocks 15 to make the precast sheet piles 1 in an overall "U" shape. The triangular support frames 8 are installed in an inverted triangular pattern on the inner wall of the precast sheet piles 1, providing support at the two side walls and the middle of the precast sheet piles 1. The metal plates 14 and metal blocks 15 are installed on the outer side of the precast sheet piles 1. When one precast sheet pile 1 connects to another, a connection and triangular support prestress are generated between the two precast sheet piles 1. This simultaneously increases the triangular prestress structure on both the inner and outer sides of the precast sheet piles 1, adding prestress to the inner and outer sides of the device. Under the action of force, and by setting up structures such as protruding blocks 2, square grooves 3 and round grooves 4, and plug-in rods 5, when the precast sheet pile 1 on the device is connected to the precast sheet pile 1 on the side, the protruding blocks 2 are inserted into the inner cavity of the square grooves 3, and the round grooves 4 on the device are simultaneously opened in the inner walls of the protruding blocks 2 and the square grooves 3. The plug-in rods 5 on the device pass through the inner cavity of the round grooves 4 to connect the connecting parts of the two precast sheet piles 1, so that the precast sheet pile 1 on the device and another precast sheet pile 1 can be strongly connected. Then, the precast sheet pile 1 is connected to the precast sheet pile 1 by threading with metal plates 14 and connecting nails 18, which increases the connection firmness between the precast sheet piles 1 when they are constructed side by side.
