The invention is applicable to the technical field of anticorrosion, and provides an anticorrosion structure and a treatment method of an outer bottom edge board of a
gas chamber. A multi-layer wrapping structure is formed on a
gas chamber wall, the
gas chamber edge board, an
asphalt mortar layer and a concrete foundation, and a
cement motor apron slope (2), an anticorrosion agent (3), a first elastic
polymer bottom
coating (4), a first elastic
polymer cement gum layer (5), a second elastic
polymer cement gum layer (6), a second elastic polymer bottom
coating (7), a viscoelastic body anticorrosion rubber belt (8) and an elastic polymer weather-resisting finishing
coating (9) are arranged from inside to outside sequentially. The surface treatment requirement is low, and the structure has the good
adhesive property with concrete, steel materials and the like, after curing, a seamless waterproof layer with a complete coating is formed, the elasticity is achieved, deformation generated by
weight bearing or high temperature of the gas chamber can be absorbed well, and the effects of no cracks, non pulling off and non falling off can be achieved; and the structure is simple, easy and convenient to construct, convenient to maintain and low in cost and saves time and labor; and the good sealing performance and anticorrosion property are achieved, and the service life can reach more than 10 years.
