Spiral soil-squeezing hole-forming sleeve follow-up concrete pouring pile-forming method
The invention discloses a spiral soil-squeezing hole-forming sleeve follow-up concrete pouring pile-forming method. The method comprises the following steps that S1, two sets of soil-squeezing power heads are installed on a spiral soil-squeezing cast-in-place pile machine; S2, the outer side of a second power head is sleeved with and detachably connected with a fixed sleeve; S3, a first power head is started, the first power head is made to rotate downwards and drill to form a hole, and then the second power head drives the fixed sleeve to drill downwards together to form the hole; S4, a reinforcement cage is manufactured, and a concrete cushion block is fixedly installed at the lower end of the reinforcement cage; S5, the fixed sleeve and the second power head are detached and separated, then the first power head and the second power head are taken out of the fixed sleeve, and then the concrete cushion block and the reinforcement cage are embedded into the fixed sleeve; S6, concrete is pumped to the inner side of the fixed sleeve; and S7, the spiral soil-squeezing cast-in-place pile machine is moved to the next pile position for construction. The reinforcement cage can be accurately installed in the middle when being installed, so that the structure of the poured reinforcement cage is more stable.
本发明公开了一种螺旋挤土成孔套管跟进灌注砼成桩方法，包括如下步骤：S1、在螺旋挤土灌装机上安装有两套挤土动力头；S2、第二动力头的外侧套设并可拆卸的连接有固定套筒；S3、启动第一动力头，使第一动力头向下旋转并钻进成孔，之后第二动力头带动固定套筒一并向下钻进成孔；S4、制作钢筋笼，并在钢筋笼的下端固定安装有混凝土垫块；S5、将固定套筒与第二动力头拆卸分离，之后将第一动力头和第二动力头从固定套筒内取出，之后将混凝土垫块和钢筋笼嵌入固定套筒内；S6、向固定套筒内侧泵送混凝土；S6、移动螺旋挤土灌注桩机至下一桩位施工。使钢筋笼在安装的时候可以准确的保证是居中安装，从而使浇筑出来的钢筋笼结构更为稳定。
