１概述近几年来，我国采用了一种新的地脚螺栓型式和新的锚固方法──钻孔锚固螺栓法。这种方式采用高强度的灌浆料把地脚螺栓锚固于螺栓孔里，３－５天后即可安装机器设备，承受载荷，改变了过去的施工工艺，大大简化了施工程序，可节省大量的钢材。随着社会的发展和生活水平?
1 Overview In recent years, our country has adopted a new type of anchor bolts and a new anchoring method ─ ─ drilling anchor bolt method. In this way, the anchor bolt is anchored in the bolt hole by high-strength grouting material, and the equipment can be installed in 3-5 days to bear the load and change the construction process in the past, which greatly simplifies the construction procedure and saves a lot of steel .
