隧道塌方救生机由安装在螺旋输送轴前端的切削头对塌方渣土进行切削,通过螺旋输送轴和救生筒将渣土排向后方。当塌方渣土被切削贯通后,将螺旋输送轴向后方抽出,救生筒即成为被困人员的逃生通道。这种新型的专用隧道塌方救生机,旨在以最小的土方工作量,尽可能减小对土体的扰动,并采用回避爆破的做法,获取最快的救援速度和最好的安全性。 The tunnel collapse lifesaving machine cuts the landslide sediment by the cutting head mounted on the front end of the screw conveying shaft and discharges the muck to the rear through the screw conveying shaft and the life-supporting tube. When the landslide was cut through the muck, the helix will be delivered axially rearward, the life-saving trap that has become trapped escape routes. This new type of dedicated tunnel collapse lifter aims to minimize the disturbance to the soil with minimum earthwork load and to avoid the blasting and get the fastest rescue speed and the best safety.
