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 following steps of: after a spiral soil-squeezing pouring pile machine is in place, starting a first power head to rotate and drill downwards to form a hole, and then starting a second power head to drive a sleeve to rotate and drill downwards to form the hole; drilling is stopped until the casing pipe of the soil squeezing drill bit and the second power head drills to the designed depth; the connection between the second power head and the casing pipe is released, a concrete pump connected with the first power head is started, concrete is pumped into the drill hole, and meanwhile the first power head and the second power head are lifted upwards till the soil squeezing drill bit is completely lifted out of the casing pipe; the reinforcement cage is clamped into the positioning assembly through the locking assembly and then lowered to the preset height along the casing pipe, and concrete is pumped into the casing pipe till the designed pile top elevation is achieved; and the second power head and the casing pipe are reconnected through the locking assembly, the second power head is started to rotate and is lifted upwards until the casing pipe completely leaves the soil layer, and then a pile can be formed. According to the device, the reinforcement cage can be quickly and stably lowered.
本发明涉及螺旋挤土成孔套管跟进灌注砼成桩方法，其包括以下步骤：螺旋挤土灌注桩机就位后，启动第一动力头旋转向下钻进成孔，然后启动第二动力头带动套管旋转向下钻进成孔，直至挤土钻头和第二动力头的套管钻到设计深度后停止钻进；解开第二动力头与套管的连接，启动与第一动力头相连接的砼泵，往钻孔内泵送砼同时向上提升第一动力头与第二动力头，直至挤土钻头完全提出套管；将钢筋笼通过锁定组件卡进定位组件，再沿着套管下放至预定高度，并向套管内泵送砼，直至达到设计桩顶标高；通过锁定组件重新连接第二动力头与所述套管，启动第二动力头旋转并向上提升，直至套管全部离开土层即可成桩。本申请有利于钢筋笼的快速且稳定地下放。
