董箐水电站右岸趾板以上均为粘结式端头锚索进行深层支护,因设计布置的锚索数量多、锚索方位角和倾角相互交错、边坡地质条件复杂、施工工期紧等因素,给施工带来许多困难。文章主要对右岸边坡锚索施工中出现的钻孔、灌浆、编索和下索、张拉等4个方面问题作初步的探讨和研究,分析出现问题的原因并提出解决和避免这些问题的方法。通过对问题的分析和讨论,得到的一些结论或经验教训对以后的锚索施工有一定的启发作用。
Due to the large number of anchor cables, the staggered azimuth and inclination of anchor cables, complex geological conditions of the slope, tight construction period and other factors , Bring many difficulties to the construction. The article mainly discusses and studies the problems of drilling, grouting, cords and cables and tension in the construction of anchor line on the right bank slope, analyzes the causes of the problems and proposes to solve and avoid these problems Methods. Through the analysis and discussion of the problems, some conclusions or lessons learned have some enlightenment on the construction of the anchor cable in the future.
