The invention discloses an urban deep foundation pit stone mechanical cutting excavation construction method, and belongs to the technical field of foundation stone construction, the construction method is composed of a construction technology and a construction method, and the construction method comprises the following steps of early-stage preparation, rail installation, foundation stone vertical face cutting, foundation stone horizontal face cutting, foundation stone cutting into blocks, and stone cleaning and outward transportation. The thickened disk saw and the rope saw are combined to cut and excavate the deep foundation pit and the pit-in-pit layered, partitioned, low-noise and accurate stone mechanically, no noise influence is caused to surrounding residents, the adverse social influence caused by complaints is avoided, the technology is advanced, the efficiency is high, meanwhile, noise is low, flying dust pollution is avoided, good economic benefits and social benefits are achieved, and the method is suitable for popularization and application. The foundation pit stone is efficiently cut off in a layered and blocked mode, full-mechanical construction is achieved, safety and reliability are guaranteed, blasting and other highly dangerous working procedures are not needed for construction, disturbance influence on a surrounding non-excavation area soil layer is avoided, and adverse influence on the surrounding stability of a foundation pit is avoided in the operation process.

    本发明公开了城市深基坑石方机械切除开挖施工工法,属于基石施工技术领域,施工工法由施工工艺和施工方法组成,包括以下步骤:前期准备,轨道安装,基石垂直立面切割,基石水平面切割,基石切割成块,石方清理外运。本发明采用加厚圆盘锯与绳锯组合对深基坑、坑中坑分层分块低噪精准石方机械切除开挖,对周居民无噪声影响,规避了被投诉的不良社会影响,工艺先进、效率高,同时低噪音、无扬尘污染,具有良好的经济效益和社会效益,分层分块高效切除基坑石方,实现全机械化施工,安全性、可靠性有保障,无需采用爆破等危险较大的工序施工,对周边非开挖区域土层无扰动影响,作业过程不会对基坑周边稳定性造成不利影响。
