Abstract

The invention relates to a tunnel smoke exhaust device, a tunnel and an installation method of a smoke exhaust valve structure. The tunnel smoke exhaust device comprises at least one smoke exhaust valve structure and a flue plate installed at the top in a tunnel body, at least one air hole is formed in the flue plate, and each smoke exhaust valve structure is installed in the corresponding air hole in the flue plate; and the height of the upper surface of each smoke exhaust valve structure is lower than or equal to that of the upper surface of the flue plate. When smoke penetrates through thesmoke exhaust valve structures to enter a smoke exhaust channel formed between the flue plate and the top of the inner wall of the tunnel body and then circulates, due to the fact that the height of the upper surface of each smoke exhaust valve structure is lower than or equal to the height of the upper surface of the flue plate, circulation of the smoke is not hindered at all; and the requirementfor the power performance of a smoke exhaust fan is reduced, the smoke circulation efficiency is improved, the power energy of the smoke exhaust fan is saved, and the technical problems that in the prior art, a smoke exhaust device fails due to insufficient power, and serious harm is brought to a tunnel structure and personnel evacuation are solved.

Description

technical field [0001] The invention relates to the technical field of tunnel ventilation and smoke exhaust, in particular to a tunnel smoke exhaust device and an installation method for tunnel and smoke exhaust valve structures. Background technique [0002] According to Article 12.3.2 of the "Code for Fire Protection Design of Buildings" GB50016-2014 (2018 Edition), for urban traffic tunnels with a length of more than 3000m and unconditional use of segmented longitudinal smoke exhaust, it is advisable to adopt a focused smoke exhaust method. Such as figure 1 As shown, in this method, a flue exhaust duct is installed on the top or side of the tunnel, an electric exhaust valve is installed on the flue duct plate at a certain distance (usually about 60m), and exhaust fans are installed at both ends of the flue exhaust duct. Open the smoke exhaust fan and the electric smoke exhaust port of the electric smoke exhaust valve near the fire source to discharge the smoke out of the...
