Problems solved by technology

First of all, due to the need for uninterrupted 24-hour lighting in the dark environment of the tunnel, the power consumption of lighting in operation and management is large, and the cost is high. As a result, many units cannot afford the operation and maintenance costs of the tunnel. Turn on the designed lighting fixtures, resulting in insufficient road lighting brightness for road tunnel operation, which brings difficulties to safe driving; secondly, due to changes in light intensity at the entrance and exit sections of the tunnel, "black holes" and "white holes" are prone to appear , causing hidden dangers to drivers and drivers; third, with the increase of the tunnel mileage, the exhaust gas content in the tunnel increases, and the air in the tunnel needs to be replaced through the exhaust system. The exhaust system has high operating costs and the exhaust effect not good

Abstract

The invention provides a construction method of a tunnel fireproof coating. The construction method comprises the following steps: spraying a silane coupling agent on a surface of a lining body as a substrate; spraying a non-expansive water-based fireproof coating on a surface of the substrate for multiple times to form a base layer with a thickness of 10-12 mm; spraying a surface layer is sprayed on a surface of the base layer, wherein a spraying technology of the surface layer comprises the following steps: dividing a portion, within 60 m, of a tunnel portal into a tunnel entrance and exit section and spraying the tunnel entrance and exit section with a water-based energy-storage luminous coating with a thickness of 0.25-0.4 mm extending inwards from the tunnel portal, wherein a thickness of coating is gradually reduced by 0.03-0.05 mm every 15 m; and spraying multifunctional water-based coating with a thickness of 0.2-0.36 mm on a middle section of the tunnel. In the construction method of tunnel fireproof coating, luminous intensity of the coating changes according to a light intensity within a 60-m range of the tunnel portal, such that a brightness difference inside and outside the tunnel portal is reduced, and phenomena of black holes and white holes in the tunnel are eliminated; and the coating on the middle section of the tunnel has light emitting and negative ion functions, such that continuous illumination can be achieved in the tunnel, air in the tunnel can be effectively purified, and operation cost of an exhaust system is reduced.

Description

Technical field [0001] The present invention relates to the field of tunneling construction, and more particularly to a construction method of a tunnel fire-proof coating. Background technique [0002] With the rapid development of my country's traffic road, the road tunnel construction is unspeakled, and a large number of tunnel construction has brought convenient to people's transportation, and there are also many management issues. First of all, due to the unexpected 24-hour lighting in the tunnel in the dark, the operation management is high, the cost is high, causing many units to unable to undertake the operation and maintenance cost of the tunnel, in China's many local road tunnels, often incomplete Open the design lighting fixture, causing the road surface of the road tunnel driving insufficient brightness, it is difficult to bring safe driving; secondly, the import segment of the tunnel and the change in the intensity of the light, it is prone to "black hole" and "white ...
