When the water in the loose sand area is saturated, ordinary sand will roll up, thus forming quicksand. If the water captured by the sand cannot be separated from it, liquefied soil will be formed, and the liquefied soil can no longer bear the weight. There are two ways to increase the rolling degree of sand and finally form quicksand.
Prevention and control: understand the areas with frequent quicksand. Although quicksand is not a special kind of soil, it may be formed as long as groundwater and sediment are mixed together, making the earth's surface sticky. This is the best way to avoid quicksand and identify the places where quicksand may occur. Places prone to quicksand include beaches, swamps and wetlands, lakes, and near underground springs.
Extended data:
Possible escape methods when encountering slow quicksand: as long as you act quickly and judge the direction accurately, you can escape. When going deep into the quicksand trap, you need to lie down quickly, reduce your physical load as soon as possible, and put your hands and feet flat on the sand to increase your buoyancy. If there is no one around, you should slowly climb to a stable position by rolling slowly or lying prone.
