劈裂式灌浆在土坝加固中的应用

Application of splitting grouting technology on the earthfill dam reinforcement

阐述了土坝坝体灌浆的分类及其适用范围,结合岩庄水库工程概况,提出坝体防渗应采用劈裂灌浆技术,从钻孔、制浆、灌浆等方面探讨了劈裂灌浆技术的施工控制措施,并对灌浆出现的问题及其处理措施进行了论述,从而保证灌浆质量,达到预期的效果。

The classfication and application scope of earthfill dam grouting were interpreted with the engineering general situation of Yanzhuang water storage reservoir, It was proposed that the seepage-preventing of dam body should adopt splitting grouting technology, The construction control measurement of which were discussed from drilling, pulping, grouting and so on, ;The grouting problems and the corrsponding disposal measurement were also discussed so as to ensure the grouting quality and reach the anticipating result.
