旧有设备基础改造中螺栓锚固技术研究

在工程中常采用多种胶结材料植筋和锚固设备地脚螺栓,但对于大直径螺栓的锚固,由于其特殊性还需进一步分析和研究。本文通过多项工程的实践和试验资料,结合有关行业规程,对大直径螺栓锚固所采用的胶结材料、锚固长度、锚孔大小及施工提出了建议,供工程设计和施工参考。

Inserting bar with several binders and anchoring equipment with foundation bolt are frequently adopted in engineering. But to the anchoring of large diameter bolt need further study and analysis for its special property. Based on the experience and test material of several engineering and the related trade specifications, the suggestion for engineering design and construction referring on the adopted binder, the length of anchoring, the size of anchor hole and work of the anchor of large diameter bolts were put forward in this paper.
