[0017] like Figures 1-5 As shown, this utility model provides a U-shaped steel sheet pile with recoverable corrosion resistance, comprising: A steel sheet pile 1 has a slot 5 on one side of its inner wall and a positioning device 2 that cooperates with the slot 5 on one side of its top end. The positioning device 2 is used to assemble and fix two steel sheet piles 1. Fixing devices 3 are respectively installed on both sides of the inner wall of the steel sheet pile 1. The fixing devices 3 are used to improve the stability of the steel sheet pile 1 when it is placed on the ground. Among them, a protrusion 4 is provided on one side of the steel sheet pile 1, and a second installation groove 6 is provided on the other side of the steel sheet pile 1.

[0018] The sheet pile 1 includes a steel plate 101. The sidewall of the steel plate 101 is provided with an anti-corrosion coating 103. Several first installation grooves 102 are opened on the sidewall of the steel plate 101. The inner wall of the several first installation grooves 102 is filled with repair capsules 104. The first installation grooves 102 are evenly distributed on the sidewall of the steel plate 101, so that the repair capsules 104 can be evenly distributed. When the anti-corrosion coating 103 is damaged and the steel plate 101 is exposed, the corrosion inhibitor flows out and comes into contact with the catalyst or moisture in the air, and a polymerization reaction occurs, filling and sealing the cracks, thereby repairing the sheet pile 1 and improving its service life. An installation frame 202 is provided at the top of the sheet pile 1. A rotating locking block 201 is rotatably provided in the installation frame 202. The limiting block 204 on the rotating locking block 201 can be inserted into the locking groove 5 in another sheet pile 1. At the same time, it is fixedly connected to the protrusion 4 by rotating bolts 203, realizing the assembly between the two sheet piles 1 and effectively improving the stability of the connection and fixation.

[0019] The positioning device 2 includes a mounting frame 202 fixedly connected to one side of the top of the sheet pile 1. A rotating block 201 is rotatably connected to the inner wall of the mounting frame 202. By rotating the rotating block 201, two sheet piles 1 can be assembled, achieving initial fixation of the two sheet piles 1. At the same time, the limiting block 204 is inserted into the slot 5, which can further improve the stability during assembly. A limiting block 204 that cooperates with the slot 5 is fixedly connected to one side of the inner wall of the rotating block 201. A bolt 203 is rotatably connected to the top of the rotating block 201. After the two sheet piles 1 are assembled, the insertion rod 304 can be inserted into the ground by pressing the pressing block 303, which further reinforces the installation position of the device, prevents displacement during use, and effectively improves stability.

[0020] The fixing device 3 includes a groove 301 formed in the inner wall of the sheet pile 1. A slider 302 is slidably connected to the inner wall of the groove 301. A pressing block 303 is fixedly connected to one side of the slider 302. The slider 302 is slidably arranged in the groove 301, and an insertion rod 304 is provided at the bottom end of the slider 302. At the same time, the pressing block 303 is provided on the side wall of the slider 302. The pressing block 303 makes it easy for workers to insert the insertion rod 304 into the ground. The protruding pressing block 303 can effectively reduce the difficulty of operation for workers during installation. The insertion rod 304 is fixedly connected to the bottom end of the slider 302. By inserting the insertion rod 304 into the ground, the device can be prevented from tipping over after assembly.

[0021] The anti-corrosion coating 103 uses epoxy resin, and the repair capsule 104 uses a corrosion inhibitor. When the coating breaks due to external force, the crack will puncture the microcapsule, and the repair agent will flow out and come into contact with the catalyst or moisture in the air, undergoing a polymerization reaction to fill and seal the crack. The bolt 203 rotates through the rotating block 201 and is threadedly connected to the top of the protrusion 4. The bottom end of the insertion rod 304 slides through the bottom end of the inner wall of the slide groove 301. The second mounting groove 6 cooperates with the protrusion 4. The cooperation of the protrusion 4 and the second mounting groove 6 can realize the rapid assembly of multiple steel sheet piles 1. After the assembly is completed, the rotation of the rotating block 201 is used to lock the limiting block 204 into the slot 5, which initially prevents the two steel sheet piles 1 from separating. At the same time, the bolt 203 is connected to the protrusion 4 to limit the rotation block 201, effectively preventing the mounting frame 202 from loosening during long-term use, thereby preventing the two steel sheet piles 1 from separating, and effectively improving the overall stability of the device.

[0022] A mounting frame 202 is installed at the top of the sheet pile 1. A rotating locking block 201 is rotatably installed in the mounting frame 202. The limiting block 204 on the rotating locking block 201 can be locked into the locking groove 5 in another sheet pile 1. At the same time, the locking block 203 is used to fix it to the protrusion 4, realizing the assembly between the two sheet piles 1, effectively improving the stability of the connection and fixation. After the two sheet piles 1 are assembled, the insertion rod 304 can be inserted into the ground by pressing the pressing block 303, which further reinforces the installation position of the device and prevents displacement during use. An anti-corrosion coating 103 is provided on the side wall of the steel plate 101, and a repair capsule 104 is provided between the steel plate 101 and the anti-corrosion coating 103. The first installation groove 102 is evenly distributed on the side wall of the steel plate 101, so that the repair capsule 104 can be evenly distributed. When the anti-corrosion coating 103 is damaged and the steel plate 101 is exposed, the corrosion inhibitor flows out and comes into contact with the catalyst or moisture in the air, and a polymerization reaction occurs, filling and sealing the cracks. A dense protective film is formed on the exposed steel surface, inhibiting the occurrence of electrochemical corrosion, thereby achieving the repair of the steel sheet pile 1 and improving its service life.
