Disassembly-free ultra-high performance concrete durability protection formwork and construction method
The invention discloses a disassembly-free ultra-high performance concrete durability protection formwork and a construction method, the protection formwork adopts ultra-high performance concrete to prefabricate formwork units, the two adjacent sides of each formwork unit are provided with protrusions, the other two sides are provided with grooves matched with the protrusions, and the inner side surface of each formwork unit is provided with irregular chiseling marks; the two formwork units are tightly connected in a matched mode through the protrusions and the grooves, and corresponding parameter design is carried out on the chloride ion content and the chloride ion permeability resistance limit value of a concrete material for protecting the formwork, so that corrosion of corrosive substances such as chloride ions and the like to a structural body to be protected in the corrosive environment is reduced to the maximum extent. The coating is suitable for various corrosive environments and has excellent corrosion resistance; the service life of an engineering structure is greatly prolonged by combining the design of the chlorine ion content and the chlorine ion permeability resistance limit value of a protective template concrete material; the construction method of the non-dismantling type ultra-high performance concrete durability protection formwork is simple in construction operation, economical and reasonable.
本发明公开了一种免拆型超高性能混凝土耐久性保护模板及施工方法，保护模板采用超高性能混凝土预制成模板单元，模板单元相邻两侧具有凸起、其余两侧具有与凸起适配的凹槽，并在模板单元的内侧表面具有不规则凿痕，两模板单元之间通过凸起与凹槽紧密配合连接，并通过对保护模板的混凝土材料的氯离子含量及抗氯离子渗透性限值进行相应参数设计，来最大程度降低腐蚀环境下氯离子等腐蚀性物质对要保护的结构体的侵蚀，以适应于多种腐蚀环境、耐腐蚀性能优良；结合保护模板混凝土材料氯离子含量及抗氯离子渗透性限值设计实现极大延长工程结构服役寿命；本发明免拆型超高性能混凝土耐久性保护模板施工方法，施工操作简单，经济合理。
