摘要
根据堆积体不同组成,选取偏心和同心跟管工艺保证成孔效率,实现快速施工,迅速稳定边坡。
In the construction of prestressed anchorage cables in Yinshuigou talus, according to the geological formation differences of every parts of the talus, the means of ＂pipe eccentrically follows upon＂ or ＂pipe concentrically follows up- on＂ for boring holes are used respectively to different parts of the talus to improve the boring efficiency and quicken the stable equilibrium of the talus slide.
