摘要
新疆地区空气干燥,昼夜温差大,致使山口碾压混凝土大坝在施工过程中出现裂缝。根据工程和地区特点以及裂缝情况,选用了表面修补、嵌缝封堵、化学灌浆加固以及与仿生自愈合法相结合的综合处理措施对裂缝进行修补;介绍了修补材料的选用要求;详细阐述了修补施工的工艺过程。修补完成后,通过压水试验及钻芯取样检测,所有裂缝均未见渗水;后期检测也未见裂缝有继续发展的趋势。其处理方法和工艺流程可供同类工程参考。
The cracks of Shankou RCC Dam in the construction process were caused by the dry air and large temperature difference in Xinjiang area. According to the project characteristics, as well as the actual situation of dam cracks, comprehensive treatment measures such as surface repairing, caulking sealing, chemical grouting and biomimetic self - healing are adopted to re- pair the cracks, the requirement of repairing materials selection is introduced, and the technological process of the repair construction is elaborated. The result shows that all the cracks have no seepage through the test of water pressure and core sampling after the repair and the cracks do not have the developing trend in the later detection. The treatment and technological process can provide references for similar projects.
