针对三峡工程永久船闸输水廊道砼层面缝的实际情况 ,从理论上对化学灌浆布孔方案进行了优化设计 ,并对传统的灌浆设备和灌浆工艺进行了改进。选用长江科学院 CW改性环氧浆材 ,并采用水平深孔、较高压、长时间、两序多孔并灌工艺及气压自动电子化学灌浆系统对层面缝进行了化学灌浆处理 ,灌后经压水试验 ,芯样劈拉强度达到了设计要求 According to the actual situation of the concrete seam of the water conveyance corridor of the Three Gorges Project Permanent Ship Lock, the chemical grouting layout is optimized theoretically, and the traditional grouting equipment and grouting technology are improved. The use of CW modified epoxy pulp material of the Yangtze River Science Institute, and the use of horizontal deep-hole, high pressure, long time, two-order porous and filling technology and pneumatic automatic electronic chemical grouting system for the seam seam chemical grouting treatment, Test, the core sample splitting tensile strength to meet the design requirements
