1mm, after enhancement layer brushing, the mylar enhancement layer of sticking glass fibre cloth or 30 ~ 40g/m2 immediately, after forbidding enhancement layer surface drying
Enhancing layer material is pasted again；
（3）Spray waterproof layer：After enhancement layer is done solid work, liquid rubber spray-coating material is begun to use to spray waterproof layer, the twice of contact apply
Layer spray paint direction should be orthogonal；When film coated surface is fully cured（It is tack-free）Afterwards, lower road spraying application can just be carried out；
（4）Repeat step（3）2 to 3 times；
（5）Make the protective layer of waterproof layer：After waterproof layer is done solid work, one layer of asphalt paper separation layer is covered on waterproof layer, plane is prevented
The protective layer of water layer is using the pea gravel concreten for pouring 8cm thickness.Facade waterproof layer（Such as turn over the facade of beam）Protective layer using thick
Polyethylene foams of the degree not less than 6mm is protected.
