Drop-in type high-durability wooden residual formwork construction [for retaining walls on steep slopes] with consideration for landscape!
High durability and 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. The risk of aesthetic deterioration due to decay, as seen with conventional wooden residual formwork, and the danger of formwork components falling off are extremely low, eliminating the need for maintenance and inspection work. It can be used for the formwork of retaining walls to prevent disasters in areas at risk of landslides on steep slopes. The wooden surface reduces sunlight reflection more than concrete. 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, allows for a shortened construction period. It can be assembled by ordinary workers without the need for specialized formwork carpenters. 【Features】 ■ The surface finish of the structure is wood-based, considering aesthetics. ■ Conservation of the surrounding environment is achieved. ■ The removal of formwork and concrete surface finishing is unnecessary, and since scaffolding for those tasks is also not needed, the construction period can be shortened. ■ Direct sunlight reflection can be prevented. *For more details, please refer to the PDF document or feel free to contact us.
