How to save yourself when the ground collapses
What is ground collapse?
Ground collapse is a geological phenomenon in which surface rocks and soil fall downward to form collapse pits under the action of natural or man-made factors. There are many forms of ground collapse, such as round, strip, oval, funnel and so on.
Why do urban roads collapse?
There are two main points: 1. Underground pipelines are disturbed by aging and rupture. At present, underground pipelines in most cities are in the "middle and late period" of pipeline life, and ground collapse is caused by pipeline damage. 2. Disturbance caused by underground engineering construction. Blasting and vibration in the process of urban construction have certain damage to the geological structure balance of underground space. Disturbance leads to the void of the bottom floor, the destruction of underground pipelines and the collapse of pavement. If the construction causes soil erosion, it is easy to cause ground subsidence or even collapse.
Self-rescue skills of ground collapse
1. Put your head in your hands, protect your face with your arms, squat down and hold a group, hide your face between your knees, and reserve maximum breathing space for yourself. 2. Keep calm, move your body carefully, and prevent a bigger collapse from hitting you. 3. Protect your nose and mouth to prevent dust pollution. 4. If you can get away, you should flee quickly and call for help if necessary. When you can't leave, you should save your strength, call for help at the right time and wait for help. If there is a signal, you should call the police quickly, or you can use the water pipes and gas pipes around you to make a sound for help. 5. If the car falls into the subsidence area, quickly unfasten the seat belt after the car stops, break the window to escape and find an escape route. If you are buried, don't panic and call for help by means of communication quickly. Don't save yourself by force, save your strength and wait for help.
