摘要
根据某工程实际的地质情况,对煤层采空区巷道的施工方案进行了介绍,重点阐述了钢护筒封隔桩基的施工工艺,提出了工程施工的质量安全保证措施,为钢护筒封隔桩基下采空区巷道施工积累了经验。
According to actual engineering conditions, the paper introduces roadway construction scheme of coal-bed mined-out area, mainly de- scribes the construction technologies of steel guard pipe sealing pile foundation, and puts forward engineering construction quality safety guaran- teeing measures, which has accumulated experience for roadway construction of steel guard pipe sealing pile foundation mined-out area.
