FIELD: construction.
SUBSTANCE: method for construction of crushed stone supports includes formation of lengthy channel in soil surface, having side wall and in general permanent area of cross section, filling a layer of crushed stone into channel with thickness approximately equal to width of cross section of channel, ramming of crushed stone layer with a ramming tip of pyramid or cone shape, in which area of the upper part or base is approximately equal to area of cross section of channel. Then stages of fill and ramming are repeated for subsequent layers of crushed stone. Area of lower surface or top of tip is not more than 20% of upper part or base area to increase transverse stresses in side wall of channel.
EFFECT: improved load-carrying capacity of support.
