METHOD FOR CORRECTING INCLINATION OF PNEUMATIC CAISSON
PROBLEM TO BE SOLVED: To provide means which can bring about a great inclination correction effect by a simple structure and which can be taken even on a job site in soft ground and a small-scale job site.SOLUTION: In a method for correcting inclination of a caisson in a pneumatic caisson method, a strut material is arranged between a caisson and a reaction surface facing an outer surface of the caisson, in such a manner as to take an attitude in which an up-grade is set toward the caisson. In sinking of the caisson, the strut material corrects the inclination of the caisson by pushing out the caisson by reaction when an attitude of the strut material is shifted to a horizontal attitude.SELECTED DRAWING: Figure 1
【課題】簡易な構造で高い傾斜修正効果を得ることができるとともに、軟弱地盤の現場や小規模な現場でも実施可能な手段を提供する。【解決手段】ニューマチックケーソン工法においてのケーソンの傾斜修正を行う為の方法であって、ケーソンと、該ケーソンの外面と対向する反力面との間に、突っ張り材を、該突っ張り材が前記ケーソンに向けて上り勾配を設けた姿勢となるように配置し、前記ケーソンの沈降時に、前記突っ張り材が水平姿勢に遷移する際の反力でケーソンを押し出して、前記ケーソンの傾斜を修正することを特徴とする。【選択図】図１
