Tunnel for fire-resistant panels, refractory coating structure and its method of construction of the tunnel

摘要

PROBLEM TO BE SOLVED: To provide fireproof panels for a tunnel, a fireproof coating structure in the tunnel, and its construction method for protecting concrete inner walls of the tunnel for an existing or newly provided road from the heat of fire. SOLUTION: The fireproof panels 6 are used for the inside of a primary lining body 3 made of reinforced concrete, a composite body of ductile case iron and concrete, or a composite body of steel and concrete constructed for the tunnel of a shield tunnel, an immersed tunnel, an NATM tunnel, or a cut and cover tunnel. The surfaces of the fireproof panels 6 to the side of air in the tunnel are made of adiabatic materials 8 covered with porous sheets 10 with a large number of holes 15.
