A Case History of Piling Work Utilizing the Press-in Method on a Steep Slope
Natural disasters, such as unprecedented typhoon, hurricane and torrential rain, have increased all over the world. Moreover, damage from heavy rainfall, in western Japan, was put in the national spotlight in 2018. Consequently, many disaster rehabilitation works are ongoing. However, it is difficult to secure enough working space in many of these sites. Therefore, it tends to delay the reconstructions. In this paper, the case study of the Gyro-press Method and the G.R.B system, which were utilized for the disaster rehabilitation work of Uto-bridge is introduced. Uto-bridge was damaged by the No. 16 typhoon which hit the southeast of Japan. Pre-fabricated piles were installed into hard ground on a steep slope and/or in narrow working space without any temporary platforms in this work.
