Stone cutting excavation construction method for deep foundation pit close to existing line
The invention discloses a deep foundation pit stonework cutting excavation construction method adjacent to an existing line, and belongs to the technical field of deep foundation pit stonework cutting excavation. Measuring and positioning the foundation pit earthwork after the base surface is leveled, and lofting the cutting height; laying a track on the earthwork base surface of the foundation pit; rock stratum vertical cutting is conducted, specifically, a double-blade mine cutting machine is adopted to conduct longitudinal and transverse interval cutting on the foundation pit earthwork into set square stones; a diamond wire saw device is adopted for conducting horizontal cutting and rock breaking on the square stones formed through longitudinal and transverse cutting; and hoisting and transferring. According to the method, cutting into blocks is conducted firstly, then rope saw sleeving horizontal cutting is conducted, punching is avoided, the rope saw chain of the rope saw cutting equipment can be conveniently arranged to the cutting starting position, the arrangement labor intensity is greatly reduced, placement is not affected by corners, the arrangement difficulty is greatly reduced, the rope saw chain can be arranged without opening, the installation efficiency is greatly improved, and the cost is reduced. And the cutting efficiency is higher.
本发明公开了紧邻既有线深基坑石方切割开挖施工方法，属于深基坑石方切割开挖技术领域，包括对基坑土方采用绳锯切割进行基面找平；对基面找平后的基坑土方进行测量定位，放样切割高度；在基坑土方基面进行轨道铺设；岩层竖向切割：采用双刀矿山切割机对基坑土方进行纵横向间隔切割成设定方块石方；绳锯切割断岩：采用金刚石绳锯设备对纵横向切割成的方块石方进行水平切割断岩；吊装转运。本发明先切割成块，后套绳锯水平切割，没有穿孔这些工序流程，方便布置绳锯切割设备的绳锯链条到切割起始位置，布置劳动强度大大降低，拐角不影响放置，布置难度大大降低，而且无需打开，即可布置绳锯链条，安装效率大大提高，切割效率更高。
