BRIDGE DECK WATERPROOFING METHOD WITH EXCELLENT TENSILE STRENGTH, DURABILITY AND WORKABILITY

摘要

The present invention relates to a bridge deck waterproofing method with excellent tensile strength, durability and workability, and more specifically, to a bridge deck waterproofing method for waterproofing a road or the deck of a bridge, which comprises: a bridge deck preparatory step of preparing a bridge deck by removing debris therefrom; a primer layer forming step of forming a primer layer by applying a primer to the bridge deck; a step of applying a rubber modified acrylic waterproof adhesive over the primer layer; a step of arranging a reinforced fiber tissue on the rubber modified acrylic waterproof adhesive; a bridge deck waterproofing sheet preparatory step of preparing a waterproofing sheet which is composed of a lower resin layer, an elasticity reinforcing sheet and an upper resin layer at the upper surface portion of the reinforced fiber tissue, and a bridge deck waterproofing sheet composed of an adhesive layer arranged at the upper portion of the upper resin layer and the lower portion of the lower resin layer, and release paper which covers the adhesive layer; a bridge deck waterproofing sheet arrangement step of separating the release paper arranged at the lower portion of the bridge deck waterproofing sheet before attaching the same on the reinforced fiber tissue; and an ASCON layer forming step of separating the release paper arranged at the upper portion of the bridge deck waterproofing sheet to apply ASCON in order to form an ASCON layer. Therefore, the reinforced fiber tissue and the rubber modified acrylic waterproof adhesive are applied to a bridge deck structure such as a steel upper plate, a concrete upper plate, and a drain pan in order to reinforce tensile strength and durability, thereby resolving the problem of the conventional bridge deck waterproofing method which uses felt that is subject to fracture and dislocation. In addition, the waterproofing sheet and the ASCON layer are prevented from being pushed by the passage of a vehicle or external forces, such that disturbances on and damage to the bridge deck can be prevented, while providing excellent constructability.;COPYRIGHT KIPO 2020
