【摘要】 为对化学灌浆技术有更好的理解,结合贵州大花水电站大坝混凝土裂缝处理工程,阐述了化学灌浆技术在水利水电工程中的应用,着重介绍了PSI-CW组液灌浆技术的工作原理、关键技术措施和施工工艺.化学浆液处理混凝土裂缝具有粘度低、亲水性好、施工灌注性能好等优点,浆液硬化后具有足够高的固结强度和较好的耐久性.更多还原

【Abstract】 In order to have a better understanding of chemical grouting,combining the concrete cracks handle engineering of Dahua Hydropower Station in Guizhou,the chemical grouting technical’s application in water conservancy and hydropower,the process principle,the key technical measures and the construction methods of PSI-CW combination grouting were mainly introduced.Chemical grouting to handle the concrete cracks has many merits,such as the lower viscosity,the better hydrophilicity,and easier perfusion,and has bonding strength and better durability after the chemical grout hardening.更多还原
