CAISSON SETTLEMENT METHOD
To provide a caisson settlement method capable of drilling without blasting a ground right below a cutting edge tip even for a hard ground, capable of eliminating noise and vibration generated accompanying blast and capable of preventing rapid settlement of a caisson.SOLUTION: A caisson settlement method in which a caisson 1 where a cutting edge 3 is provided under a bottom plate is installed in a ground 4, and the caisson 1 is settled by drilling the ground 4 below the cutting edge 3 includes a ground drilling step of drilling the ground 4 under a cutting edge tip 31 by jetting high pressure water toward the ground 4 below the cutting edge tip 31 of the cutting edge 3 by a high pressure water jetting device 6.SELECTED DRAWING: Figure 1
【課題】硬質地盤であっても刃先の直下の地盤を発破せずに掘削できて発破に伴い発生する騒音や振動を無くすことができるとともに、ケーソンが急激に沈下することを防止できるケーソンの沈下方法を提供する。【解決手段】底板の下に刃口３が設けられたケーソン１を地盤４に設置し、刃口３の下方の地盤４を掘削してケーソン１を沈下させるケーソンの沈下方法において、高圧水噴射装置６で刃口３の刃先３１の下方の地盤４に向けて高圧水を噴射して刃先３１の下方の地盤４を掘削する地盤掘削工程を有する。【選択図】図１
