Rotary excavating cast-in-situ bored pile construction method
The invention belongs to the technical field of foundation engineering construction, and particularly relates to a rotary excavating cast-in-situ bored pile construction method which comprises the following steps: step 1, geological survey and analysis, geological survey and pile test work in advance, geological data and drilling parameter acquisition, geological data analysis and parameter determination, combined analysis of geological data and pile test data, and construction of a rotary excavating cast-in-situ bored pile; according to the method, the drilling technology and geological data are utilized, the thickness and the distribution condition of the intermediary weathering interlayer are analyzed in detail, a high-power and high-torque rotary drilling rig is adopted in advance, and a proper drilling tool and drilling teeth are matched. The series of measures obviously improve the construction speed and the overall engineering efficiency. In addition, according to accurate drilling and geological data, the matched drilling tool and drilling tooth are selected, resource waste is reduced, particularly, abrasion of the drilling tool and the drilling tooth is reduced, and therefore the rock entering efficiency is effectively improved, and resource waste is reduced.
本发明属于地基工程施工技术领域,具体涉及一种旋挖钻孔灌注桩施工方法,包括以下步骤:步骤一:地质调查与分析,预先地质勘察和试桩工作,获取地质数据和钻进参数,地质数据分析与参数确定,对地质数据与试桩数据进行结合分析,以确定中风化夹层的地质结构、分布区域和厚度参数本发明,利用钻探技术和地质数据,通过详细分析中风化夹层的厚度和分布情况,提前采用高功率和高扭矩的旋挖钻机,并搭配合适的钻具和钻齿。这一系列措施显著提高了施工速度和整体工程效率。此外,根据精确的钻探和地质数据选择匹配的钻具和钻齿有助于减少资源浪费,特别是降低了钻具和钻齿的磨损,从而有效提高入岩效率、减少资源浪费。
