How to choose a liner plate construction method? *Reference materials for method comparison are currently being provided.

Introducing methods suitable for repairing upstream bridges where large heavy machinery access is difficult, including ways to reuse liner plates! What construction methods are suitable for shortening construction time and reducing labor?

This document explains the construction method using retaining materials widely known as the liner plate method. Various methods are considered mainly for bridge pier repairs, and it is widely examined as a suitable foundation and retaining method in areas such as upstream rivers where heavy machinery cannot access. [Document Introduction *Excerpt] ■ Methods suitable for the removal of accumulated sediment around bridge piers ■ Methods that have achieved the reuse of liner plates ■ Comparison materials for various liner plate methods *Overview, features, water-stopping methods, advantages, disadvantages, etc. are introduced. Our company handles methods suitable for temporary closures (using liner plates) for bridge piers, sluices, etc. *For more details, please download the PDF or feel free to contact us.

basic information

【Temporary Deadline F P S Method】 In existing methods (using water-stopping packing), if the shape of the bridge pier and the closing frame become larger, it may not be possible to perform assembly work on bracket-type scaffolding. We have developed a solution that can accommodate all conditions by using a lightweight floating platform. "Water-stopping packing + Floating platform" 【Pump Dredging Method (Obstacle Avoidance Type)】 By installing a long nozzle at the bottom of the dredging frame, which incorporates underwater sand pumps, air pumps, and high-pressure pumps, it has become possible to dredge only the sediment from sedimentary layers mixed with obstacles such as driftwood and boulders. *For more details, please download the PDF or feel free to contact us.
