[0069] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , working principle:

[0070] When in use, the second channel steel 3 is used to reinforce the overall equipment.

Two third channel steels 20 are installed inside the transverse bridge inner mold 15 to achieve a supporting and stabilizing effect.

The overall structure is simple and easy to operate, without using a large number of equipment for auxiliary use, saving the overall installation and usage cost;

[0071] According to the slope change law of the pier column, the outer membrane uses the two side templates of the pier column to wrap its two positive side templates. To adapt to the 9-meter fixed-length steel bars, considering the economy and stiffness of the templates, the templates can be designed to be 3 meters high, and the width is based on the maximum width at the bottom of the pier column. For the convenience of construction, the transverse distribution beams on the two side templates of the pier column extend 0.2 meters outside the templates for tensioning with high-strength tie rods. For the two side templates on the front, the distribution beams are slightly shorter than the template width, and their vertical positions are just staggered from the distribution beams of the side templates. Considering the flatness of template splicing and the accuracy of position, positioning pins and male-female tenons are set on the upper and lower interfaces of the templates. Since there is no scaffold on the outside of the pier column, a safety platform is set on the template. The platform is 0.9 meters away from the upper opening of the template, with a width of 0.65 meters. The height of the platform railing is 1.2 meters, and anti-slip steel grating is laid inside the platform.
