摘要
微型桩是在基坑开挖前按照一定间距、布置多根或多排相互独立的微型桩,经过钻孔’清孔,注浆,插管’二次补浆等工艺提前针对潜在滑体进行加固,再通过小吨位预应力锚杆、钢管锚杆、挂网喷锚、腰梁等工艺使边坡更稳固。
The potential sliding body can be reinforced in advance by drilling,hole cleaning>grouting,intubation,secondary grouting and other processes according to a certain spacing and arrangement of multiple or multiple rows of independent micro-piles before foundation pit excavation.The slope is stabilized by small tonnage prestressed anchor,steel pipe anchor,net-hanging spray anchor and waist beam.
