硫铝酸盐水泥速凝浆液在锚索钻孔固壁中的试验与应用

Test and Application of Sulpho-aluminate Cement Quick Setting Slurry in Anchor Cable Boring for Wall Consolidation

摘要:

为解决福堂水电站厂区高边坡锚索钻孔施工中成孔困难的问题，经过室内试验研究，采用以硫铝酸盐水泥为主剂，掺加专用早强剂和专用缓凝剂配制而成的速凝浆液，大大缩短固壁灌浆后扫孔待凝时间，提高锚索造孔施工工效。详细介绍了试验过程、试验结果、工程应用情况及效果。

Abstract:

To solve the difficulties of borehole completion in high slope anchor cable drilling construction for Futang hydropower plant, by the laboratory experimental study, the quick setting slurry with sulpho-aluminate cement as main agent adding special early strength agent and retarder was taken, which greatly shortened the hole cleaning and stay setting time after grouting for wall consolidation, improved the construction efficiency of anchor cable boring. The paper introduced the testing process, testing results, engineering application and the effects in detail.
