8. The method as claimed in claim 7, wherein the first and second support plates each include first and second connection plates spaced apart in a width direction of the stack, and elastic connection members are provided between the first and second connection plates.

9. The method for quickly constructing the underground slide rail type rescue channel according to claim 6, wherein the rescue channel is formed by the following steps:

s41: controlling the support shell in the strutting state to be connected with the guide assembly;

s42: cleaning the accumulation body near the guide assembly to form an accommodating cavity for placing the support shell in an expanded state, and controlling the support shell to be placed in the accommodating cavity;

s43: firstly cleaning the accumulated body in the range of a rescue cavity in the supporting shell, and then continuously cleaning the accumulated body near the guide assembly to form an accommodating cavity for placing the next supporting shell in an expanded state;

s44: the support shell in the contraction state is controlled to penetrate through the rescue cavity of the accumulation body after cleaning, and is controlled to be spread and placed in the corresponding accommodating cavity in the contraction state and connected with the guide assembly;

s45: steps S43 and S44 are repeated until a rescue channel is formed.

10. The method for quickly constructing the underground slide rail type rescue channel according to claim 8, wherein an auxiliary slide rail is arranged on the bottom surface of the rescue cavity in the support shell, and the support shell in the contracted state is suitable for penetrating through the rescue cavity in the support shell in the expanded state through the auxiliary slide rail.
