LPF method for temporary closure supporting pier reinforcement with abundant achievements.
Over 90 construction achievements and more than 110 target bridge piers. Supporting bridge pier reinforcement work nationwide safely and efficiently with proven know-how.
The "Temporary Closure LPF Method" is a well-established technique for constructing temporary closures using liner plates in underwater structures such as rivers, seas, and dams. By minimizing custom components for each pier and allowing for shape selection based on site conditions, it contributes to shortening the construction process and ensuring stable construction quality. It is also compatible with manual construction, having numerous successful projects even in sites with strict headroom restrictions (approximately 1.0m). *Please take a look at the collection of case studies summarizing our construction achievements. 【Features】 ■ Composition of liner plates + H-beam reinforcement rings + support structures ■ Assembled above water and then installed underwater ■ Compatible with narrow and vibration-free construction ■ Usable even under low headroom conditions
