三类坝在除险加固工程中发现前期由于地质勘查不到位,设计采用充填灌浆,不能有效解决问题,首先要进行详细的地质勘查,查清大坝地质构造。大坝粘土心墙在坝轴线位置,但粘土心墙顶部高程较低,粘土心墙以上有一层砂碎石层,只能采用高聚物定向劈裂注浆防渗技术彻底截断渗漏通道。文章就高聚物注浆技术在水库中的应用进行探讨。
Three types of dams found in the project of strengthening and eliminating danger In the early stage, due to the lack of geological survey, the design of filling grouting can not effectively solve the problem. Firstly, detailed geological survey should be conducted to find out the geological structure of the dam. The center of the dam clay core is at the axis of the dam, but the top of the clay core wall has a low elevation. There is a layer of sand and gravel above the clay core wall. Only the polymer-based fracturing grouting seepage control technology can be used to completely cut off the leakage channel. The article discusses the application of polymer grouting technology in reservoirs.
