Construction method for controlling drilling depth of cement mixing pile
The invention relates to a construction method for controlling the drilling depth of a cement mixing pile, which comprises the following steps of: 1, moving a cement mixing pile machine in place, and measuring a hole position and the initial height of a drilled hole; secondly, drilling is conducted through the cement mixing pile machine, the initial height of a drill rod is measured by observing the range finder, and therefore the drilling speed and the drilling designated depth are measured; thirdly, after the rotating rod is controlled by the lifter to drill to the designed pile length or the hard soil layer, in-situ guniting stirring is conducted for 0 s, then the stirring head is reversed from the pile end to be lifted and stirred at the constant speed, and cement grout is continuously sprayed to the ground; step 4, repeating the step 2 and the step 3 for re-stirring; and 5, stirring is finished, and the pile machine is moved to the next point. The method has the characteristics of improving the accuracy degree of the drilling depth, improving the construction quality, reducing the construction difficulty, reducing the construction cost and the like.
本发明涉及一种控制水泥搅拌桩钻入深度的施工方法，包括以下步骤：步骤一：水泥搅拌桩机移动就位，对孔位以及钻孔初始高度进行测量；步骤二：水泥搅拌桩机开钻，通过观看测距仪测量钻杆的初始高度，从而测得钻入速度以及钻入指定深度；步骤三：通过升降机控制转杆钻进至设计桩长或硬土层后，原地喷浆搅拌0秒，然后将搅拌头自桩端反转匀速提升搅拌，并连续喷入水泥浆液，直至地面；步骤四：重复步骤二及步骤三进行复搅；步骤五：搅拌结束，桩机挪至下一个点。本发明具有提高钻入深度的精确程度、提高施工质量、降低施工难度、降低施工成本等特点。
