FIELD: fire-extinguishing method by fire spread prevention, particularly by creation of fire barriers before fire front, and fire-extinguishing equipment. SUBSTANCE: mobile fire- extinguishing method on base of reusable fire barrier embodiments includes digging out of fire prevention trench in direction parallel to fire front, creation of fire barrier, introducing of fire- extinguishing substance into fire barrier by filling of low-permeability reservoir arranged between side plates and base, forming of base of reinforced concrete, equipping of base facing fire front with through orifices closed by plugs of heat- sensitive material having melting temperature not less than 100 C, or introducing of fire extinguishing substance into protective reservoir formed of heat-resistant material which faces fire front, securing of reservoir to reinforced concrete plate with height less than trench depth. Fire extinguishing substance extinguishes fire and prevents damage of reinforced concrete plate due to superheating thereof. EFFECT: increased reliability of fire spread prevention method, reduced possibility of fire penetration through fire barrier, low assembling time, enhanced manufacturability. 6 cl, 7 dwg |
