The specific settings are as follows:

[0052] Please refer to Figure 1 , the support steel pipe frame 1 includes an extension steel pipe 11 and a reinforcement steel pipe 12; among them, there are two groups of the extension steel pipes 11, and the two groups of the extension steel pipes 11 are arranged in a parallel extension manner from the ladder frame a, and the two groups of the extension steel pipes 11 are fixedly connected and assembled through the reinforcement steel pipe 12, so as to stably extend the support steel pipe frame 1 from the ladder frame a to the position of the pier b.
