The question of asylum is most easily resolved if a piece of plastic film or cloth is found in the victims of the accident. Then, after spending just a few minutes, you can build a primitive fabric canopy.
The simplest primitive emergency shelters and shelters in treeless and small forests, fabric huts and awnings.
To do this, a long ceiling pole is laid in the bifurcation or in the direction of the bitch and thick branches of two trees standing close to each other, which will serve as the basis for the entire structure. With the pole before laying, it is necessary to cut off any protruding knots and burrs so that they do not damage the film. If there are no suitable branches located at the same level, in the center of the trunk, in the bark, you can make V-shaped notches in which to wedge the ends of the ceiling pole. It is even easier to use a rope tightly stretched between the trunks as a ceiling beam. True, the rope does not always provide sufficient structural rigidity..
A plastic film forming the roof is poured onto the ceiling beam from above. Loosely hanging halves of polyethylene must be pulled apart so that two symmetrical slopes are formed, and fixed on the ground, laying heavy stones, wood fragments, lumps of earth on top. If fabric is used instead of polyethylene, it can be fixed by nailing the ends to the ground with several pointed pegs. More reliable peg with a knot extending to the side (flyer), which presses the fabric to the ground.
The angle between the ramps is selected depending on the capacity of the shelter and the material used. Dull corners provide a large internal area of the hut, but prevent the rapid dripping of raindrops. Shorter angles increase water resistance, but reduce the internal area of the shelter. The most common and universal for all cases is an angle of 90 degrees. For huts in which polyethylene or other waterproof fabrics are used as covering material, it can be increased at least up to 120 degrees. For rapidly wetting tissues, reduced to 50-60 degrees.
