    Application of digital construction of the minor-disturbance four-axial soil mixing pile

    • 摘要: 针对水泥土搅拌桩施工过程中数字化程度低、桩体质量难控、施工数据无法回溯等问题,以微扰动四轴搅拌桩为依托,研发了数字化搅拌桩施工云平台,云平台由数字化施工控制系统、云服务器和交互平台组成,实现成桩过程数据的实时追踪与反馈。通过数字化施工云平台,施工前输入同地层匹配的成桩参数,实现了变参数的自动化施工;输入与钻头提升速度相匹配的钻杆转速,控制搅拌次数大于规范要求值;输入地内压力控制阈值,实现施工过程中对地基土的微扰动,实测土体侧向位移和地表隆起均控制在毫米级范围;通过钻头垂直度实时监测,桩体垂直度可达到1/250;通过管理云平台,实现参建各方对施工质量的动态管控。研究成果对于全面提升搅拌桩施工质量和软基施工数字化水平具有重要的实践意义。

       

      Abstract: Aiming at the problem of quality control of a deep mixing pile in construction process, this paper introduces a novel digital construction cloud platform incorporated in the equipment minor-disturbance four-axial soil mixing pile, realizing the real-time tracking and feedback in construction process. After inputting the parameter related to different strata into the platform, the variation of parameter is automatically controlled in construction. After inputting the threshold of underground pressure, the minor-disturbance to subsoil is realized with a measured soil lateral displacement and upheaving in millimeter scale. With a measurement of verticality of drill rod in real time, the pile verticality can be controlled to 1/250. The management cloud platform realizes a dynamic management of quality control for all parties in the construction. This practical results are beneficial to completely improve the construction quality of the deep mixing pile and digital construction level of soft soil.
