Vacuum preloading construction structure and method for soft soil foundation
The invention relates to a vacuum preloading construction method for a soft soil foundation, and belongs to the technical field of soft soil foundation treatment. A vacuum preloading construction structure for the soft soil foundation includes a plurality of drainage plates inserted below the soft soil foundation, a plurality of parallel horizontal branch pipes are arranged at the top ends of thedrainage plates in a communication mode, each horizontal branch pipe communicates with a plurality of drainage plates, a same main drainage pipe is arranged at the top ends of the multiple horizontalbranch pipes in a communication mode, the main drainage pipe is provided with vacuum-pumping equipment in a communication mode, the horizontal branch pipes are each provided with a plurality of sets of anti-settling components in the own axis direction, the anti-settling components each include a supporting column driven vertically below the foundation, the lower surfaces of the supporting columnsare connected with the bottoms of the horizontal branch pipes in an abutting mode, sliding sleeves slidably sleeve the top ends of the supporting columns, and the sliding sleeves are hollow inside and are provided with supporting rods capable of lifting up as the supporting columns descend and supporting the horizontal branch pipes in a hinged mode along both sides in the axial direction of the horizontal branch pipes. The vacuum preloading construction structure for the soft soil foundation has the effect of preventing settlement of the communicating pipes along with the foundation.
本发明涉及软土地基真空预压施工方法，属于软土地基处理的技术领域，其包括插入于软土地基以下的多根排水板，排水板的顶端连通设置有多根相互平行的水平支管，且每一根水平支管连通多根排水板，多根水平支管的顶端连通设置有同一根排水总管，排水总管连通设置有抽真空设备，所述水平支管沿着自身轴线方向设置有多组防沉降组件，防沉降组件包括竖直打入地基以下的支撑柱，支撑柱的下表面与水平支管的底部抵接，支撑柱的顶端滑动套设有滑套，滑套内部中空且滑套沿着水平支管轴线方向的两侧铰接设置有能够随着支撑柱下降而向上抬起并支撑水平支管的支撑杆，本发明具有避免连通的各管道随着地基一起发生沉降的效果。
