在日本桩基础施工机械的种类和施工方法很多,其中,螺旋钻孔机就是经常使用的大口径快速钻孔机的一种。日本最早的螺旋钻孔机是1954年7月由日本开发机社制造的,用气泵驱动并附有轮胎,施工能力很低。1953年,西松建设株式会社、清木建设株式会社从美国引进技术,通过特殊的螺旋钻杆向地下注入水泥浆或砂浆,筑成了能够承受较轻载荷的桩和挡土用的连续墙。1962年,光工业株式会社在大开挖施工的地铁和其它地下建筑的挡土墙时,使用了螺旋钻孔机。随着螺旋钻孔机使用率
There are many types and construction methods of construction machinery for pile foundations in Japan. Among them, spiral drilling machines are one of the commonly used large-diameter fast drilling machines. The earliest Japanese auger drilling machine was manufactured by Japan Development Machine Co., Ltd. in July 1954. It was driven by an air pump and attached tires. The construction capacity was very low. In 1953, Nishimatsu Construction Co., Ltd. and Clear Wood Construction Co., Ltd. introduced technology from the United States and injected cement slurry or mortar into the ground through a special spiral drill pipe to form a continuous wall for piles and retaining soil that can withstand light loads. In 1962, Kogyo Kogyo Co., Ltd. used an auger drilling machine to excavate the retaining walls of subways and other underground structures under construction. With the use of spiral drilling machine
