| 摘 要： | 三峡右岸大坝2003年夏秋季需浇筑基础约束区混凝土,为避免固结灌浆施工造成混凝土长间歇,决定将部分基础有盖重固结灌浆变更为无盖重方式施工.介绍无盖重固结灌浆过程易发生且对灌浆质量影响较大的几种特殊情况的质量控制方法.虽然无盖重固结灌浆存在种种不利于灌浆质量的因素,但通过精心施工,严格质量管理,该工程固结灌浆质量满足设计要求.

| Abstract: | The concrete of foundation constrained zone at TGP right bank dam was placed in 2003 summer.In order to avoid long term interruption of concrete placement due to consolidation grouting construction,the partial foundation consolidation grouting under covered concrete was changed to conduct without concrete covering.The quality control measures for several special conditions which have comparably large influence on grouting quality and easily occur in consolidation grouting process without concrete covering are mainly presented.Although the unfavorable factors influencing grouting quality exist in consolidation grouting without concrete covering,through elaborate construction and strict quality management,the consolidation grouting quality meets the design requirement. |
