Expanded Application of the Hydro-Jet RD Water-Jet Method to the Horseshoe-Shaped Dowel System

「To accommodate horseshoe-shaped dowel systems, which require considerable time to remove, we verified cutting conditions and safety through analysis, model testing and loading tests, and established a control standard of a cutting height of 30 mm ± 5 mm. As a result, we achieved the required accuracy and removal speed in actual construction, shortening the schedule by approximately 10 days for each direction compared with the standard method.」
