摘　　要：岩壁吊车梁开挖施工是水电站地下厂房施工中质量要求最高、工艺要求最严格、技术难度最大的关键部位。岩壁吊车梁开挖的成型质量直接影响到后期岩壁梁的运行安全,是岩壁梁成败与否的第一关键要素,复杂地质条件下岩壁梁开挖难度更大,对技术要求更高。笔者介绍一种2号岩石乳化炸药的药卷切割装置,用于解决需要准确间隔装药时人工使用刀具切割炸药效率低、人员投入大等问题,大大地提高了分割药卷的精准度,加快光面爆破小药卷制作速度。The construction of the rock-bolted crane girders is the key part with the highest quality requirement,the strictest technology requirement and the greatest technical difficulty in the underground powerhouse construction of hydropower station.The excavation quality of rock-bolted crane girders directly affects the operation safety of rock-bolted crane girders in the later stage,and is the first key factor for the success of rockbolted crane girders.Under complex geological conditions,rock-bolted crane girders excavation is more difficult and has higher technical requirements.This paper introduces a kind of 2#rock emulsion explosive roll cutting device,which is used to solve the problems of low efficiency and large personnel investment in manual cutting of explosives with knives when accurately spaced charges are demanded.This device can greatly improve the accuracy of splitting the rolls and accelerates the production speed of small rolls for smooth blasting.
