Spiral soil-squeezing hole-forming sleeve follow-up concrete pouring pile-forming method
The invention relates to a spiral soil-squeezing hole-forming sleeve follow-up concrete pouring pile-forming method which comprises the steps that 1, two sets of soil-squeezing power heads are installed on a spiral soil-squeezing filling machine, a drill bit is arranged at the bottom end of the first power head, the peripheral side of the first power head is sleeved with a second power head, and the second power head is connected with a sleeve; 2, a plurality of positioning blocks are placed in the sleeve in advance, and the positioning blocks at the bottom end protrude out of the inner wall of the sleeve; 3, a first power head is started for drilling, a second power head is started to rotate, and the casing pipe is driven to move into a drill hole; 4, a reinforcement cage is placed, and the bottom end of the reinforcement cage is clamped and matched with the positioning blocks; and 5, concrete is pumped in, when the height of the concrete reaches the top end of the sleeve, the sleeve is lifted, the positioning block is placed again, and the concrete is pumped in till the concrete submerges the reinforcement cage. The gap between the reinforcement cage and the sleeve is filled with the multiple positioning blocks, the end of the reinforcement cage is limited, and the reinforcement cage is located in the center of the sleeve.
本申请涉及一种螺旋挤土成孔套管跟进灌注砼成桩方法，包括：步骤1、在螺旋挤土灌装机安装有两套挤土动力头，第一动力头的底端设置有钻头，第二动力头套设于第一动力头的周侧，第二动力头连接有套管；步骤2、在套管内预先放置有若干个定位块，令底端的定位块凸出于套管的内壁；步骤3、启动第一动力头进行钻孔，启动第二动力头旋转，带动套管向钻孔内移动；步骤4、放置钢筋笼，令钢筋笼的底端与定位块卡接配合；步骤5、泵入混凝土，当混凝土的高度达到套管的顶端时，提升套管，重新放入定位块，泵入混凝土，直至混凝土没过钢筋笼。本申请利用多个定位块填充钢筋笼与套管之间间隙，对钢筋笼的端部进行限位，令钢筋笼处于套管的中心。
