the simplest type of storage facility for agricultural products. It consists of a banked-up heap of potatoes, root crops, or cabbage, placed on the surface of the ground or in a shallow trench (0.2-0.5 m deep) and covered with layers of straw (sawdust, peat, and so forth) and earth. Clamps are placed on elevated sites with slanting sides, protected from the predominant winter winds and with deep-lying subsoil waters. The dimensions of a clamp and the thickness of its cover depend on what is to be stored and the climatic conditions of the area. In the central zone of the European part of the USSR clamps are usually 2-2.2 m wide and 1.0-1.2 m high and are covered by a layer of straw that is 0.5 m thick at the base and 0.35 m thick at the crown. The layer of earth is 0.6 m thick at the base and 0.5 m at the crown. The total thickness of the cover must be equal to or a little greater than the average depth at which the soil freezes in the area. Clamp coverers, excavators, and other machines are used to mechanize the covering operation. The temperature inside the clamp is regulated by means of ventilation or by changing the thickness of the cover.
