Excavation method suitable for hard rock stratum enlarged foundation
The invention discloses an excavation method suitable for a hard rock stratum enlarged foundation. The excavation method comprises the steps that the range of the needed foundation is determined; a drilling track is arranged along the periphery of the foundation; a drilling machine is used for drilling along the drilling track so as to separate a foundation; a crusher is used for crushing the foundation, and broken stones are removed; the broken foundation is locally polished to ensure that the foundation is flat; and the foundation is checked and accepted. According to the method, the drilling machine is adopted to conduct automatic drilling along the drilling track so that the foundation can be separated from the peripheral area, a user does not need to hold a water drill to cut the periphery of the foundation, the construction efficiency can be effectively improved, and the labor intensity of operators can be effectively reduced. Besides, the crusher is used for crushing the foundation, a blasting mode is not needed for crushing operation, the crushing degree of the foundation can be effectively controlled, a rock layer of the foundation is prevented from being damaged, and the risk of accidents of operators can be reduced.
本发明公开了一种适用于硬质岩层扩大基础的开挖方法，包括：确定所需基础的范围；沿基础的周部设置钻孔轨道；利用钻机沿钻孔轨道钻孔，以分隔出基础；利用破碎机对基础进行破碎，并清除碎石；局部打磨破碎后的基础，以确保基础平整；检查验收基础。本方法采用钻机沿钻孔轨道进行自动钻孔，以将基础与周边区域分开，且无需人工手持水钻切割基础的周部，可有效提高施工效率和降低操作人员的劳动强度。此外，本发明利用破碎机对基础进行破碎，无需采用爆破的方式进行破碎操作，可有效控制对基础的破碎程度，避免对基础的岩石层造成破坏，可降低操作人员发生意外事故的风险性。
