[0027] Specifically, both ends of the second side template 2 are inlaid with protrusions 10, and the side template and the U-shaped template 11 can be quickly connected together through the mortise and tenon structure. One end of the protrusion 10 is fixedly connected to the U-shaped template 11, and the outer side of the U-shaped template 11 is fixedly connected to the first connecting column 12. The inside of the first connecting column 12 is slidably connected to the elastic block 13, and the inside of the elastic block 13 is spirally connected to the threaded rod 14. The outer side of the threaded rod 14 is spirally connected to the column block 15, and the outer side of the column block 15 is fitted with a second connecting column 16.

[0028] Furthermore, a sealing strip 17 is provided on the outer side of the protrusion 10, and the material of the sealing strip 17 is rubber. Under the action of the sealing strip 17, the tightness of the connection is increased, and the occurrence of gaps that cause concrete leakage is prevented.

[0029] Furthermore, one end of the threaded rod 14 is fixedly connected to a limiting block 18, and the cross-sectional area of the limiting block 18 is larger than the cross-sectional area of the threaded rod 14. Under the action of the limiting block 18, the tensioning block 13 can be prevented from sliding out of the inside of the threaded rod 14, thereby playing a limiting role.

[0030] It is worth noting that a bottom plate 19 is inserted into the lower portion of the first side formwork 1 , and an anchor rod 20 is inserted into the interior of the bottom plate 19 . The anchor rod 20 can connect the concrete to the ground to improve stability.

[0035] Working principle and process:

[0036] When the staff needs to cast the gate pier in one go, first place the first side formwork 1 in an appropriate position, insert the connecting bottom plate 19 at the lower part of the first side formwork 1, and insert the anchor rod 20 into the inside of the bottom plate 19, hammer it into the ground, fix the position of the first side formwork 1, and at the same time, the poured concrete gate pier can be connected to the ground to improve stability. The connecting plate 22 is embedded at the top of the first side formwork 1, and then the second side formwork 2 is installed on the top of the first side formwork 1, and the carbon fiber reinforced composite plate 21 is inserted and connected together. The carbon fiber reinforced composite plate 21 is not only strong but also light in weight, which is convenient for the staff to install. The protrusion 10 fixedly connected to one side of the U-shaped formwork 11 is inserted into the inside of the side formwork. Under the action of the sealing strip 17, the tightness of the connection is increased to prevent gaps from causing concrete leakage. Then, the threaded rod 14 is rotated to drive the tension block 13 to move, so that the first connecting column 12 and the second connecting column 16 are clamped together, so that the U-shaped formwork 11 is tightly fitted with the side formwork to prevent excessive external force from causing The generation of gaps improves the sealing effect and prevents the possibility of leakage. Under the action of the limit block 18, the elastic block 13 can be prevented from sliding out from the inside of the threaded rod 14, playing a limiting role. At the same time, the threaded rod 14 can also be directly slid vertically, which is convenient for rapid disassembly of the template, reducing the labor intensity of the staff, facilitating the recycling of the template, and reducing the cost of use. Then, the tension screw 4 is inserted into the interior of the second side template 2. With the support of the plastic water-stop pad 3, the anti-loosening nut 6 inside the double nut 7 is tightened to make the double mountain block 8 drive the steel pipe 9 It fits with the second side formwork 2 and supports the second side formwork 2 to prevent the second side formwork 2 from being deformed due to excessive lateral pressure. Concrete is poured inside the formwork. Under the action of the cross bar 23 and the connecting rod 24, because it forms a triangular structure, it can effectively resist the lateral pressure and gravity of the concrete, and prevent the formwork from deformation, displacement or even collapse. When cracks appear inside the pier concrete and water seepage channels appear, the water stop 5 can effectively block the water infiltration path, prevent water from leaking out from the gaps in the concrete structure, and improve stability.
