In an emergency, the projection device part projects an image to the ground by some projection technologies; the image forms a large arrow pattern on the ground; an arrow in the pattern points to a safety exit, a quick passageway, an excavation rally point or other emergency excavation directions; and the fire-fighting spraying device sprays a large amount of water around and to the ground so as to realize functions of extinguishing the fire, absorbing the air heat, reducing the surrounding temperature, adsorbing smoke particles and adsorbing and dissolving toxic and harmful gas. The safety insurance is supplied to people who want to escape.

The invention belongs to the field of underground engineering construction, and particularly relates to a wide-span deep buried metro station structure designed through the combination of a Y-shaped column and an anti-pulling pile. The wide-span deep buried metro station structure is characterized in that the bifurcated top of the Y-shaped column is connected to a top board beam, the middle part of the Y-shaped column is connected with a middle board beam, the lower end of the Y-shaped column is connected with a bottom board beam, the top end of the anti-pulling pile is connected with the lower surface of a bottom board, and the anti-pulling pile is arranged in the Y-shaped column span of the bottom board. The top part bifurcated fulcrum of the Y-shaped column is adopted to design the metro deep buried underground structure to reduce the top board span of the underground structure, the bottom board span is reduced by means of the bottom board anti-pulling pile, a design method for the wide-span user space between the top and bottom boards is created, under the condition that the engineering cost is not increased, the structure force bearing of the top board and the bottom board is reasonably solved and the problem of dense columns and nets in the use space of passengers is solved, and thus improving the use comfortableness of the station.
