A prefabricated collapsible heat-insulated supergreenhouse comprises a frame, fixed on soil, formed by semicircular arcs of pipes or profiles, which form arches, and a transparent continuous film cover which is fixed to the frame. At the end of the greenhouse a door is arranged, all the arches of the frame are connected between each other from above by means of a longitudinal ceiling pipe (longitudinal beam), and on the sides by means of longitudinal wooden bars, to which the transparent cover is fixed. A free end thereof is pressed to the earth by soil or other any heavy natural or artificial articles from below. The arches have vertical straight-line portions for forming vertical walls, and the greenhouse itself consists of several units, moving autonomously, each the successive of which has the external size lesser than the internal size of the previous unit. All the units have the same length and are mounted in such a manner as to allow moving in the longitudinal direction of the greenhouse. The utmost units at the ends have the door and the multilayer transparent cover, and the utmost arches of the units along the contour are provided with compactors. |
