Support for seismic reinforcement and pier construction! "Temporary Closure LPF Method" *Case study collection available.
Construction is possible even with a headroom limit of 1.5m or less! Achieves excellent water stopping performance with simplicity and speed!
The "Temporary Closure LPF Method" is a construction method for building temporary closures for underwater structures such as rivers, seas, and dams using liner plates. It addresses the issues of conventional closure methods and supports bridge pier reinforcement with "simplicity, speed, and excellent water-stopping capability." It can be implemented using only manual labor. This groundbreaking NETIS-registered method can be used in environments with a headroom restriction of 1.5 meters or less! Please feel free to contact us for more information! *Currently, we are offering a collection of case studies featuring the construction results of the "Temporary Closure LPF Method" for free exclusively to Ipros users! 【Features】 ■ Composed of liner plates (waterproof specifications), water-stopping rubber gaskets, H steel (reinforcement rings), and cutting beams ■ Can be constructed using only manual labor! ■ Construction is possible with a headroom restriction of approximately 1.5 meters! ■ Vibration-free, allowing construction close to existing structures (gas, electricity, water pipes, etc.)! ■ NETIS registration: CB-110010-VE (patented) *For more details, please refer to the catalog.
