摘要
莲花水电站引水系统进水口后边坡山高陡峭,地质条件复杂。文章介绍了采用扇形孔爆破施工技术,利用2号引水隧洞进口方向前期已开挖的施工导洞,采用此项技术进行2号进水口的高边坡开挖,取得较好效果。
The side slope behind the water intake of water diversion system in Lianhua water power station is high and precipitous. The geologic condition is complex. The paper introduces the fan shaped round blasting technique that is used to excavate the high side slope of No2 water intake with diversion tunnel along the direction of No2 intake,the result is good.
