METHOD OF FIRE SUPPRESSION Russian patent published in 1999 - IPC

FIELD: fire suppression in places difficult-to-reach. SUBSTANCE: method provides for formation of protective strip from flexible pipe with radial holes. Flexible pipe is secured on terrain by anchoring device on plugged end of pipe and laid along protective strip by flying vehicle up to the source with substance for fire suppression. Fire suppression substance is suppled under pressure through radial holes of pipe to zone of protective strip. To provide for possibility of pipe laying over considerable distances by joining pipes on any terrain, flying vehicles are located successively in direction of pipe laying in protective strip. First, flying vehicle is located with pipe which is to be added, and secondly, the other flying vehicle i located with pipe to be added to pipe of the first flying vehicle. Both pipes are secured to hovering flying vehicles; catching device is brought out of the second flying vehicle; after coupling of catching device with pipe of the other flying vehicle, pipe is pulled into the second flying vehicle. Then pipes are joined and their fastenings are released and laying of formed common pipe by flying vehicle is continued. EFFECT: higher efficiency.
