Construction that takes into account the water discharge period and water level fluctuations is possible. A temporary closure method that allows for the reinforcement of bridge piers while considering the river environment.
The temporary cutoff LPF method is a construction technique that allows for work on the reinforcement and repair of bridge piers in rivers, taking into account water level fluctuations and work constraints. After assembling the tubular structure above the water surface, it is installed underwater, enabling construction to proceed while minimizing impact on the river environment. It can accommodate low headroom conditions and narrow river cross-sections, and is used in maintenance and management work for river bridges. *Case studies of construction in river projects are available. 【Features】 ■ Temporary cutoff structure using liner plates ■ Above-water assembly and underwater installation method ■ Accommodates low headroom and narrow areas ■ Construction that minimizes vibrations is possible
