Deep soft foundation reinforcement construction method
The invention discloses a deep soft foundation reinforcement construction method. The method comprises the steps that a first drill rod is installed on a rotary power head of a deep pile stirring machine; starting a grouting pump to spray water, and drilling a first drill rod into the ground from a first position beside the construction hole in a direct circulation manner; the grouting pump is closed, the first drill rod is detached from the rotary power head of the deep mixing pile machine, and the second drill rod is installed on the rotary power head of the deep mixing pile machine; the grouting pump is started to spray water, the second drill rod is drilled into the construction hole to a first set depth, and the first set depth is smaller than the length of the second drill rod; the grouting pump is closed, and the second drill rod is detached from the rotary power head of the deep mixing pile machine; the first drill rod is installed on a rotary power head of the deep stirring pile machine, and the first drill rod is lifted out of the ground; the first drill rod and the second drill rod are connected, and the first drill rod and the second drill rod form a main drill rod; and deep mixing pile forming operation is started. According to the deep stirring drilling machine with the low drilling depth, ultra-deep pile deep stirring operation is achieved, and the construction cost is saved.
本申请公开了一种深层软基加固施工方法，包括：将第一钻杆安装在深搅桩机的旋转动力头上；开启注浆泵喷水，将第一钻杆从位于施作孔一旁的第一位置处正循环钻入地下；关闭注浆泵，将第一钻杆从深搅桩机的旋转动力头上拆开，将第二钻杆安装在深搅桩机的旋转动力头上；开启注浆泵喷水，将第二钻杆钻入施作孔至第一设定深度，第一设定深度小于第二钻杆的长度；关闭注浆泵，将第二钻杆从深搅桩机的旋转动力头上拆开；将第一钻杆安装在深搅桩机的旋转动力头上，将第一钻杆从地下提出；连接第一钻杆和第二钻杆，第一钻杆和第二钻杆形成总钻杆；启动深搅成桩作业。本申请以低钻深的深搅钻机实现了超深的深搅桩作业，节约了施工成本。
