Many infrastructures such as roads, water conservancy and electric power have been damaged in Dali County, Shaanxi Province. How should we recover after the disaster?

Dalou County Transportation Bureau attached great importance to it and immediately launched the emergency plan for flood control, making careful arrangements, taking this work as the starting point and the end result of the study and education of Party history, immediately organizing professional and technical personnel to formulate a smooth work plan for emergency repair, fully mobilizing personnel, mechanical equipment and emergency repair materials, striving for sunny day and night, working overtime to carry out highway emergency repair, and successively investing more than 15 people and more than 5 sets of mechanical equipment. * * * opened 12 roads, repaired 188 roads damaged by water, and concentrated on repairing 57 roads, which ensured the safety of people's travel and was highly praised by drivers and the masses.

the heavier the rain, the more concentrated the time, and the more water will flow into the river. If a large amount of water flows into the river in a short time, and the amount of water exceeds the maximum transport capacity of the river, floods and floods will occur. In addition, the formation of floods is also influenced by natural factors such as local climate, underlying surface and human activities.

Excessive logging, serious vegetation destruction and increased soil erosion have reduced the ability of water conservation, runoff regulation, peak cutting and land filling in the basin; Sediment flows into the river, silting up and raising the riverbed, reducing the flood discharge capacity of the river. Be sure to stay calm, quickly judge the surrounding environment, and move to mountainous areas or higher places as soon as possible; If you can't escape for a while, you should choose a relatively safe place to avoid the flood. Usually, the flood caused by the sudden collapse of the blockage after the water level rises due to earthquake, landslide or glacier blocking the river is classified as dam-break flood.

dam breaks and floods are usually short-lived and unpredictable, with high peaks, rapid changes and great harm. Water is relatively mobile, not to mention the rapid flood. It can enter the room through any gap, decompose the building, make the building topple instantly, decompose it into pieces, and flow downward with the direction of the flood. Under the continuous influence of floods, almost everything in cities or mountain villages may be washed away or razed to the ground. Under the high-speed impact of floods, people often have no time to respond or even call for help.
