Beschreibung
Zusammenfassung:	A tunnel mud inrush and water inrush early warning blocking device comprises a vault retaining wall arranged at the top of a tunnel, a cross beam is arranged below the vault retaining wall, and a lowering seam of a roller shutter is reserved in the middle of the cross beam. A limiting groove is formed in the position, corresponding to the roller shutter, of the side face of the tunnel, is in a concave shape and extends in the roller shutter descending direction to limit the roller shutter descending position; a space is reserved between the cross beam and the vault retaining wall; a roller shutter and a motor for driving the roller shutter are mounted in the space; a camera is installed at the top of the tunnel, and soil pressure gauges are arranged on walls on the two sides of the tunnel.By means of the structure, the tunnel mud inrush water inrush early warning blocking device is simple in structure, fast to implement and capable of saving emergency treatment time. 一种隧道突泥突水预警阻挡装置，包括设在隧道顶部的拱顶挡墙，所述的拱顶挡墙下方设有横梁
