[0031] Working principle: When the utility model is used, the user first uses a crane on site to assemble the pier body steel formwork 2, and pads the joints of the pier body steel formwork 2 with double-sided adhesive strips to make the joints of the pier body steel formwork 2 smooth and tight, without misalignment or misalignment, to ensure that no leakage occurs at the joints during concrete vibration. Through manual cooperation construction, after trial assembly and trimming, a release agent is applied, and then the pier body steel formwork 2 is hoisted. Then the user fixes one end of the wind-tie steel cable 4 to the top of the surface of the pier body steel formwork 2, and then inserts the embedded anchor rod 51 into the ground, so that the soil-breaking cone head 54 and the anti-slip clamp 53 enter the soil, and then pulls the embedded anchor rod 51 upward for a certain distance through the triangular reinforcing rib 55, so that the anti-slip clamp 53 located in the inner cavity of the rectangular slide groove 52 rotates after being blocked by the soil and is in close contact with the soil. At this time, the embedded anchor rod 51 is installed and fixed, and then the user sets the docking slot 8 on the surface of the docking clamp plate 7 to tighten the base 3 After the pier body steel formwork 2 is installed and fixed, the user straightens the wind grip cable 4 and passes the end of the wind grip cable 4 away from the pier body steel formwork 2 into the inner cavity of the fixing seat 63, and bends the wind grip cable 4 between the two fixing seats 63 to form an anti-slip bend 65, and then rotates the extrusion bolt 64 to make the extrusion bolt 64 threaded down and the bottom end of the extrusion bolt 64 tightly pressed against the surface of the wind grip cable 4 to fix the wind grip cable 4. Then the user rotates the operating handle 9, and the operating handle 9 drives the pushing threaded rod 62 to rotate during the rotation. The pushing threaded rod 62 pushes the sliding seat 61 through its surface thread during the rotation, so that the wind grip cable 4 can be tightened and fixed, and then the pier body steel formwork 2 is tightened and fixed through the wind grip cable 4. After the pier body steel formwork 2 is installed and reinforced, the cross-crossing method is used to align and check the top center of the pier body steel formwork 2 with the center area of ​​the pier body installation area 1, and the verticality of the pier body steel formwork 2 is checked with a hammer ball hanging line.
