全套管钻孔法也称为贝诺特工法,是钻孔桩基础的主要施工方法之一。配合这个施工工艺的设备称为全套管设备或全套管钻机。由法国贝诺特公司于20世纪50年代初开发和研制。日本从1954年引进全套管钻机,并于20世纪60年代初由日本三菱重工业公司开始进行技术改造,到80年代形成目前通用的贝诺特全套管钻机。随着液压技术的日臻完善,全套管钻机的机种和施工均有很大发展。
The full-pipe drilling method, also known as Benote’s method, is one of the main construction methods for bored pile foundations. Equipment with the construction process known as the full set of pipe equipment or full casing rig. Developed and developed by French company Benote in the early 1950s. Japan introduced full-pipe drilling rigs from 1954 and began technical transformation by Japan’s Mitsubishi Heavy Industries Co., Ltd. in the early 1960s. By the 1980s, Benoy’s all-pipe drilling rig, now commonly used, was formed. With the improvement of hydraulic technology, the production and construction of full-pipe drilling rigs have greatly developed.
