Treatment method for soft soil and liquefied soil interbed foundation
The invention belongs to the technical field of foundation treatment, and relates to a treatment method for a soft soil and liquefied soil interbed foundation. The method is not influenced by the stratigraphic distribution sequence. The method comprises the following steps that (1) construction paying-off and site leveling are carried out; (2) a pile machine is in place, specifically, the pile machine is moved, and a drill bit is aligned with a pile position; (3) cement slurry is prepared, specifically, mixing is carried out by using a high-speed mixer according to the proportion so as to prepare the cement slurry; (4) pre-stirring and sinking are carried out, specifically, a mixer generator is started, and stirring, soil cutting and sinking are carried out through a drill rod; and (5) guniting, stirring and lifting are carried out, specifically, a cement slurry pump is started, and rotating is carried out while guniting is carried out. According to the method, the soft soil and liquefied soil interbed foundation is treated through cemented soil cored piles, the problems of insufficient foundation bearing capacity and soil liquefaction can be solved at the same time through the cemented soil cored piles, the engineering cost is low, and the construction period is short.
本发明属于地基处理技术领域，是一种软弱土和液化土互层地基的处理方法，该法不受地层分布顺序的影响。该方法包括以下步骤；（1）施工放线及场地平整；（2）桩机就位：将桩机移动，将钻头对准桩位；（3）制备水泥浆：按照配比使用高速搅拌机进行搅拌而制备水泥浆；（4）预搅下沉：启动搅拌机发电机，钻杆搅拌切土下沉；（5）喷浆搅拌提升：开启水泥浆泵，边喷浆，边旋转。本发明中，采用水泥土加芯桩对软弱土与液化土互层地基进行处理，水泥土加芯桩可以同时解决地基承载力不足和土体液化问题，工程造价低、施工工期短。
