GROUND STRENGTH MEASUREMENT METHOD
PROBLEM TO BE SOLVED: To provide a ground strength measurement method for measuring ground strength at an actual excavated hole part mainly at a time of pile installation and objectively confirming that the excavated hole has reached the ground.SOLUTION: A ground strength measurement method is for measuring strength of a ground A reached by an excavated hole B when the excavated hole is formed by excavating a ground by excavation means. A measurement rod insertion hole 18 is formed on the excavation means for having a rotary support shaft 12 thereof pierce through the rod insertion hole, and when the excavated hole B has reached a desired depth, a bottom end 23 of a measurement rod 20 inserted into the measurement rod insertion hole 18 is made to reach the ground A to be measured, and ground strength of the ground A to be measured is measured by ground strength measurement means 21 that uses the measurement rod 20.SELECTED DRAWING: Figure 1
【課題】主に杭施工時の実際の掘削穴部における地盤強度を計測することができ、掘削穴の地盤到達を客観的に確認することができる地盤強度計測方法の提供。【解決手段】掘削手段により地盤を掘削して掘削穴Ｂを形成する際に掘削穴が到達した地盤Ａの強度を計測する地盤強度計測方法であって、掘削手段にその回転支軸１２を貫通する計測用ロッド挿通孔１８を設けておき、掘削穴Ｂが所望の深さまで到達した際、計測用ロッド挿通孔１８に挿通させた計測用ロッド２０の下端部２３を計測対象地盤Ａに到達させ、計測用ロッド２０を用いた地盤強度計測手段２１により対象地盤Ａの地盤強度を計測する。【選択図】図１
