摘要
水封作为洞库的关键技术,如何有效地对洞室开挖过程中揭露的比较大的裂隙面出水点及时进行封堵,减少地下水流失成为衡量水封效果好坏的重要指标。以在建某地下水封洞库施工巷道典型裂隙面出水为例,简要分析裂隙面出水的原因,避免涌水发生后盲目注浆带来的人力、物力的损失。
Water enclosed as the key technology of caverns,how to effectively plug the outflow point of the larger fracture plane exposed in the excavation process and reduce groundwater loss has become an important index to measure the effect of water enclosed. Taking the outflow of typical fracture plane in construction roadway of a underground water enclosed cavern as an example,the causes of outflow of fracture plane are briefly analyzed to avoid the loss of manpower and material resources caused by blind grouting after water inflow.
