摘要
岩石无声胀裂剂在石方开挖中具有独有的应用效果,文中结合浑源恒山水库工程的实际试验对岩石无声胀裂剂的具体施工方案、操作步骤、注意事项进行详细介绍,工程当地岩石为石灰岩,充填胀裂剂钻孔的孔距选定为0.35m,排距为0.4m,胀裂后的裂缝宽度为2mm至8mm。
The soundless cracking agents of rock has special applied effect in excavating rock.Combining with the actual test in Hengshan Reservoir Project,the paper introduces the concrete construction plan,the operation steps and the matters needing attention of application of soundless cracking agents.The rock stratum in situ of Hengshan Reservoir is limestone.The selected distance between drilling holes filling soundless cracking agents is about 0.35m,the distance of two lines of holes is 0.4m,and the widths of crack after expanding and cracking are from 2mm to 8mm.
