[0032] After the installation is completed, the folding plate 30 can be opened and the supporting area can be adjusted, which is conducive to adapting to the support requirements of different specifications. After the reinforcing rod 31 is installed, the top end of the reinforcing rod 31 is embedded in the reinforcing mouth 32, so that the folding plate 30 can be supported, thereby improving the supporting strength of the folding plate 30, which is conducive to the construction support use of underground projects, high-rise buildings, large bridges and industrial plants.

[0047] The anti-corrosion coating forms a dense film on the surface of the stent, isolating the stent from the corrosive medium and preventing the corrosive medium from directly contacting the stent surface. The anti-corrosion coating contains chemical substances that can slow down the corrosion rate and can react with the corrosive medium, thereby slowing down the corrosion rate of the stent and extending the service life of the stent.

[0048] During operation, after the transmission mechanism drives the cross bar 12 to move, the inclination angle of the support rod 21 can be adjusted, and then the sliding height of the support tube 23 and the surface of the vertical rod 22 can be adjusted, and then the support height of the top plate 27 can be adjusted, which is convenient for adapting to support requirements of different heights after installation. After the installation is completed, the folding plate 30 can be opened, and then the support area can be adjusted, which is conducive to adapting to support requirements of different specifications. After installing the reinforcement rod 31, the top end of the reinforcement rod 31 is embedded in the reinforcement mouth 32, so that the folding plate 30 can be supported, thereby improving the support strength of the folding plate 30.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
