1 工艺特点本工法的应用,能使保留岩体形成平整、光滑的边坡面;在建筑物基础保护层(或隧洞)开挖中,能减少基础(或隧洞周边)超、欠挖量,并较一般的保护层(或隧洞)开挖方法在施工质量、安全、进度、经济及文明施工等方面可获得明显的效益。2 适应范围本工法应用于边坡成形、建筑物基础保护层、地下隧洞开挖,尤其对裂隙比较发育的中硬岩体,采用本工法比采用预裂
1 Process Features The application of this method can make the retaining rock body to form a smooth and smooth side slope. During the excavation of the foundation protective layer (or tunnel) of the building, the foundation (or surrounding area of the tunnel) And more general protection (or tunnel) excavation method in construction quality, safety, progress, economy and civilized construction can obtain obvious benefits. 2 Adaptation This method is applied to slope formation, building protective layer, underground tunnel excavation, especially for the relatively developed fractured hard rock mass, the use of this method than the use of pre-cracking
