Embodiment
[0031] Example : the present invention is illustrated below in conjunction with the actual situation of implementation:
[0032] The inner wall of a certain tunnel is constructed using the technology of the present invention:
[0033] First, manually remove oil, dirt and dust on the base layer of the inner wall of the tunnel, and block the source of seepage where there is water seepage; then spray a dot-shaped interface agent bonding layer material on the base layer of the inner wall of the tunnel with a spraying machine, which is made of ordinary refractory It is a material mixed with water-soluble resin, in which the ratio of refractory material and water-soluble resin is 1:0.75, and its bonding strength is greater than 0.15MPa, so as to enhance the bonding force of the inner wall base layer and prevent cracking and hollowing Then, on the base layer of the inner wall of the tunnel, spray the material imitating the fireproof board several times with a shotcrete machine to f...

The invention discloses a construction technology of a fire-prevention like plate of a tunnel, and relates to an interior decoration technology of the tunnel. The construction technology of fire-prevention like plate of the tunnel comprises the following steps: (1) cleaning up a substrate on an inner wall of the tunnel; (2) spraying a bonding substrate; (3) spraying a fireproof layer; (4) flattening; (5) leveling; (6) binding gaps; (7) spraying colored paint; and (8) spraying finish-coat paint. According to the process provided by the invention, the defects of an existing technology can be overcome, and the construction technology is convenient and easy to construct, not high in cost, and the obtained fire-prevention like plate is stable and durable; the process provided by the invention has the advantages: firstly, the bonding layer, the fire-proof layer and the substrate can be integrally bonded to improve the stability of the fire-proof layer; secondly, the fire-prevention like plate is bright in color and attractive and elegant in appearance and is free from potential safety hazards; thirdly, the fire-prevention like plate is good in durability and can be washed with water; fourthly, the fire-prevention like plate is easy to construct and relatively low in cost. Therefore, the construction technology of the fire-prevention like plate of the tunnel is applicable to the construction of inner wall beautification and decoration of the tunnel.
Description
technical field [0001] The invention relates to a fire-proof board of a tunnel, and at the same time relates to a technology for interior decoration of the tunnel. Background technique [0002] The inner walls of urban road tunnels and expressway tunnels need decoration and fire protection. Under normal circumstances, there are three kinds of decoration methods: one is to use fire-resistant paint to paint the inner wall surface. This method is commonly used on the inner wall of expressway tunnels. Rough, easy to stick to dust and difficult to clean; the second is to use tiles, which are commonly used on the inner wall of urban road tunnels. Its advantages are neat and beautiful, and can be washed, but the construction cost is high, and the tiles will fall off after a long time, which poses a safety hazard; The third is to use fireproof boards for decoration. This method needs to install keels in the tunnel arch circle, and then install fireproof boards on the keels one by o...
