Afterwards, it will fall freely under the action of gravity; the supply truck 8 is placed in the through pipe 5, and the two pipes 9 are brought into the other end of the through pipe 5, and air and drinking water are fed into the trapped area. Remove food from the supply cart.

Example

As shown in Figure 1 to Figure 3, a certain subway passed through an intrusive contact zone. Due to the poor nature of the surrounding rock and high groundwater level, it encountered avalanche problems and 3 people were trapped inside. Therefore, the system of the present invention can be quickly implemented to rescue the trapped persons. First, use a forklift to quickly transport the gravity pool 1 to a distance of 2.0m in front of the collapsed body, where the side with the jack 3 faces the collapsed body; quickly inject water into the gravity pool 1. At the position close to the rear side wall at the rear, 3 vertical boreholes were drilled into the bottom of the subway, and 3 stuck piles 2 were driven into the borehole; then the other 3 gravity pools were placed in sequence behind the former with a forklift. Close to each other, and at the rear of each gravity pool 1, set up the piles 2 according to the above method; place the cone 6 of the shuttle system horizontally on the collapsed body, the cone tip faces the collapsed body, and the height is the same as that of the jack 3. Insert the piercing tube 5 into the tail of the cone head 6, connect the piercing tube 5 to the jack 3 in turn, hold the enlarged head 4 at the end of the jack 3, start the jack 3 and move it forward. At this time, the piercing tube 5 is on the jack Under the action of 3, it gradually moves into the collapsed body. When the jack 3 reaches the maximum range, retract the jack 3 and install a through tube 5, and then press the jack 3 again, in this way until the cone 6 is removed from the collapsed body After passing through, the cone 6 will fall freely under the action of gravity; put the replenishment truck 8 in the through pipe 5, bring the two pipes 9 to the other end of the through pipe 5, and send air and air into the trapped area. Drinking water, the trapped personnel remove food 12 from the supply truck 8.
