日本自1958年引进贝诺托冲抓锥挖孔机和1960年引进卡尔威尔托回转挖斗机以及1962年引进乍尔兹盖塔反循环钻机以后,开始大量采用灌注桩施工法。理由之一是可以防止噪音、振动等建筑公害,另一方面,这种施工法可以做成大直径灌注桩,以适应大型建筑物的需要。 据文献记载,欧美各国的贝诺托、卡尔威尔托、瓦特逊、马库阿尔帕晋等各公司的 Japan introduced a large number of cast-in-place pile construction methods since the introduction of Benoto’s rush-cone digging machine in 1958, the introduction of the Calverto rotary bucket in 1960, and the introduction of the Holzgate reverse-circulation drilling rig in 1962. One of the reasons is that it can prevent construction noise such as noise and vibration. On the other hand, this construction method can be used to make large-diameter cast-in-place piles to meet the needs of large buildings.
