A plurality of fixing pins 6 are evenly distributed in a row and pass through, so that the lower fixing frame 1 is fixedly connected to the ground.

[0031] The working principle of this utility model:

[0032] (1) First, a row of fixing pins 6 are driven into the ground to fix the plate 5, thereby fixing the utility model to the ground;

[0033] (2) Then loosen the bolt connection assemblies on the lower fixing frame 1 and the upper fixing frame 2, and the steel sheet pile 7 passes through the outer clamping plate 11 and the inner clamping plate 12 of the upper fixing frame 2 from top to bottom, and the bottom extends into the space between the outer clamping plate 11 and the inner clamping plate 12 of the lower fixing frame 1, and the bottom end of the steel sheet pile 7 is supported on the ground, and then rotate the handle 42 to drive the bidirectional screw 41 to rotate, and the left slider 44 and the right slider 45 on the bidirectional screw 41 move toward or away from each other. When the left slider 44 and the right slider 45 move toward each other, the left slider 44 and the right slider 45 drive the two groups of connecting rod assemblies to contract, so that the upper fixing frame 2 moves downward. When the left slider 44 and the right slider 45 move away from each other, the left slider 44 and the right slider 45 drive the two groups of connecting rod assemblies to open, so that the upper fixing frame 2 moves upward, until the spacing adjustment between the lower fixing frame 1 and the upper fixing frame 2 is completed;

[0034] (3) Tighten the bolt connection assemblies on the lower fixing frame 1 and the upper fixing frame 2 so that the steel sheet pile 7 is clamped between the outer clamping plate 11 and the inner clamping plate 12 of the lower fixing frame 1 and the upper fixing frame 2 to prevent the steel sheet pile 7 from tilting forward and backward;

[0035] (4) All the positioning adjustment bolts 18 on the rotating lower fixing frame 1 are rotated. Since the inner end of the screw rod of the positioning adjustment bolt 18 is connected to the positioning block 19 in a rotational connection structure, when the positioning adjustment bolt 18 rotates, the positioning block 19 does not rotate synchronously. Moreover, since the positioning adjustment bolt 18 is threadedly connected to the threaded hole 17, when the positioning adjustment bolt 18 rotates, it moves in the direction of the strip groove 16, thereby driving the positioning block 19 to move in the direction of the notch of the strip groove 16 synchronously. The limit slider 112 on the positioning block 19 moves along the corresponding horizontal slide bar. 111 slide synchronously to achieve the purpose of guiding and limiting. When the limiting slider 112 slides to the outermost end of the horizontal slide bar 111, the positioning block 19 extends into the outside of the strip groove 16 and is positioned in the corrugated groove of the steel sheet pile 7, further squeezing the steel sheet pile 7. Then repeat the above steps, rotate all the positioning and adjusting bolts 18 on the upper fixing frame 2 until a row of positioning blocks 19 on the upper fixing frame 2 is positioned in the corrugated groove of the steel sheet pile 7, thereby preventing the steel sheet pile 7 from tilting left and right through the guiding positioning of the upper and lower rows of positioning blocks 19.
