The invention by as related to the bonding method of bridge deck waterproofing, how and asphalt of the bridge deck, uniform spraying and coating of silica and epoxy the construction consisted by mechanical equipment enables a uniform spraying of precision coated with silica sand for epoxy resin to reduce labor costs, shortening, and wishes to provide the mechanization construction of the spray device and the silica sand and resin waterproof coating waterproof manner for using the same method, silica sand and resin for waterproofing method that can provide a construction defect improvement.
That is, the present invention relates to a spraying device (1) of silica sand and water, methods for the resin; Automatic electronic control devices to operate as endless orbiting type driving body 2 and the installation by configuring the driving body (2) and the upper front and each resin spraying means (3) to the rear silica sand spraying means (4) and of,
Gangsangpan used as a bridge deck using this, the concrete upper surface to remove impurities such as latency Su adsorbed on the bridge deck (11) of the FRP top plate processing step, a waterproof manner resins (undercoating), the first coating step, water resistant · ways resin (middle) second coating step, a silica sand spraying process, and waterproof manner resins (resolution), the third coating step, a select coating spraying step, bridge deck waterproofing of the bridge deck performing asphalt laying process in order for in the bonding method, and the method of the asphalt concrete, and it allows the waterproof and method for resin (middle) may be made at the same time the second coating step, a silica sand spraying process mechanically.
