闸底井注浆封堵处理实践

Practice of Grouting Sealing for the Well under Gate Base

摘要:

闸基下安装监测设备时需施工设备井，在施工及使用过程中因井封堵不严出现喷水冒砂现象。结合宿鸭湖水库工程，介绍了闸底井注浆封堵的方案设计和施工工艺，对侧向挤压注浆的注浆压力、水灰比及注浆措施进行了阐述，并对注浆原理及注浆效果进行了分析。

Abstract:

Equipment well should be built under the pocket floor for the installation of monitoring equipments, while sandboils and waterspouts often occur in the construction and running process because of lax sealing. The paper introduces the system design of grouting cementing for the well under pocket floor and the construction process; discusses the grouting pressure of lateral extrusion grouting, water-cement ratio and grouting measures and analyzes the grouting principle and effects.
