一、前言近几年,在研讨岸滩、陆缘、城市近郊的大型规划和考虑正在滨海地带密集的化学工厂、石油储备基地的大地震时的液化现象对策时,地基处理工程起着非常大的作用.其施工方法和工程条件是多样的.但常遇到深部处理等困难的施工条件. SWING施工法是采用水泥类固化材料进行地基处理的代表、是兼备深层混合处理施工法和高压旋喷施工法的优点而开发的施工方法.其特点是使用能扩缩自如的翼形钻头.
I. INTRODUCTION In recent years, foundation treatment projects have become very large when considering large-scale planning of the shore beaches, continental margins, and suburban areas of the city, and considering the liquefaction countermeasures in the event of a major earthquake in a coastal chemical plant and oil reserve base. The role of the construction method and its engineering conditions are varied. However, it often encounters difficult construction conditions such as deep treatment. The SWING construction method is a representative of the foundation treatment using a cement-based solidified material, and it is a combination of a deep-layer mixing treatment method and a high-pressure rotation. The construction method developed by the advantages of the spray construction method. Its characteristic is the use of wing-shaped drills that can expand and contract freely.
