Drop-in type high-durability wooden residual formwork construction [used on the downstream side of the dam] with consideration for landscape!
High durability with consideration for the landscape! Conservation of the surrounding environment can be achieved! No need for formwork removal or scaffolding, shortening the construction period!
"The drop-in type high-durability wooden residual formwork construction" achieves long-term durability through unique wood preservation technology! It promotes the use of wood and contributes to the global environment. The estimated lifespan based on decay test results is over 50 years. Conventional wooden residual formwork poses risks due to deterioration affecting aesthetics and the potential for formwork components to fall off, making its use common on the upstream side. Our products enable use on the downstream side due to their high durability. Maintenance and inspection work to prepare for decay or the detachment of formwork components are unnecessary. There is no need for scaffolding during formwork assembly (installation of a catwalk for pouring). The elimination of formwork and scaffolding removal, as well as concrete surface finishing, leads to a reduction in construction time. Assembly can be done by ordinary workers without the need for formwork carpenters. [Features] ■ The surface finish of the structure has a wooden texture, considering aesthetics. ■ Conservation of the surrounding environment is achieved. ■ The removal of formwork and concrete surface finishing is unnecessary, and scaffolding for those tasks is also not required, resulting in a shortened construction period. ■ Direct sunlight reflection can be prevented. *For more details, please refer to the PDF materials or feel free to contact us.
