As described in the background art, a critical stable slope body is a slope body in a critical stable state, and when the slope body of the type is disturbed by excavation, a slope is easy to occur to cause a safety accident. The mountain is inevitably required to be excavated in the construction of foundation engineering. And the critical stable slope body formed on the steep hillside is easy to have geological disasters such as collapse, landslide, debris flow and the like, thereby greatly increasing the construction difficulty, endangering the national property, endangering the safety of constructors by more serious persons and bringing troubles to engineering construction. The existing construction platform cannot meet the constructive construction under a steep slope body, the construction condition under a critical stable state is not considered at the beginning of design, equipment is only limited to a low terrain or a small slope with a low gradient, and the construction platform cannot be applied to the constructive construction under the condition of the steep terrain.
