FIELD: forestry, particularly forest fire fighting, namely ground fire spread prevention.
SUBSTANCE: method involves simultaneously cutting two parallel grooves in ground and filling the grooves and passes, which are formed during disc working tools raising, with mixture of ground and combustibles present on ground surface. Mixture volume may be varied by changing of working tool submersion depth. Length of pass filled part may be varied by device movement velocity change. Device for above method realization comprises frame and disc working tools installed on posts hinged to the frame so that concave working tool sides face forwards. Device is provided with side walls mounted on frame and with two coverers located behind disc working tools. The posts are fastened one to another by means of pivotally connected turnbuckle to provide depth of working tool travel measurement.
EFFECT: increased reliability of fire-protection strip forming and, as a result, improved fire safety of forests.
