FIELD: construction.
SUBSTANCE: protective-airtight seismic-resistant device of the tunnels of transport driveways and walkways of buried structures, for example, gas shelters, is proposed. It contains a coaming with a gate, seismic abutments, locks for locking the gate, sealing loops for the airtight closing of the gate. Also, the proposed device contains pumping stations with power hydraulic cylinders for closing and opening the gate, electrical equipment and facilities. Wherein the coaming in the tunnel is installed with a gap in relation to its ceiling and side walls, fixed airtightly to the tunnel floor by its base, and the gap is covered by a flexible pliant airtight partition.
EFFECT: increasing the reliability.
