Over 80 construction achievements! We support bridge pier reinforcement nationwide with "shortened construction periods and expanded application scope"!
The "Temporary Closure LPF Method" is a construction method for building temporary closures of underwater structures such as rivers, seas, and dams using liner plates. The Temporary Closure LPF Method contributes to shortening construction periods and ensuring holidays through the following means: - Reducing the production of custom components for each pier - Selecting suitable shapes based on site conditions It can be implemented using manual labor alone and is feasible in environments with a headroom restriction of approximately 1.0 meters or less. *Please refer to the case study collection that includes examples of the construction achievements of the "Temporary Closure LPF Method." 【Features】 ■ Composed of liner plates, H-beams (reinforcement rings), and supports ■ Assembled in a cylindrical shape above water and installed underwater ■ Construction is possible with a headroom restriction of approximately 1.0 meters! *Record: 1.2m ■ Vibration-free construction is possible in narrow spaces! *For method comparison materials and construction case studies, please download the PDF to view.
