Pile forming equipment for stiffening core composite drainage pile and construction method of pile forming equipment
The invention discloses pile forming equipment for a stiffening core composite drainage pile. The pile forming equipment comprises a stiffening core steel pipe; the outer steel pipe support is coaxially arranged on the outer side of the stiffening core steel pipe; the bottom of the pile body excavation and pouring assembly is detachably connected, and the pile body excavation and pouring assembly comprises an air pipeline which perpendicularly penetrates through the pile body excavation and pouring assembly in the axis direction and is arranged between the stiffening core steel pipe and the outer steel pipe support; the grouting channel comprises a first grouting channel arranged above the permeable layer and a second grouting channel arranged above the stiffening core inner layer; the slurry pumping channel comprises a first slurry pumping channel arranged above the permeable layer and a second slurry pumping channel arranged above the stiffening core inner layer; cast-in-place construction is conducted on the permeable shell and the stiffening core at the same time through equipment to form the stiffening core composite drainage pile, the construction efficiency is improved, use of a precast pile stacking site can be greatly reduced, and the space utilization rate of the site is increased; and a hole digging mode is used instead of a prefabricated static pressure pile, so that a soil squeezing effect is avoided, and construction is facilitated.
本发明公开了一种用于劲芯复合排水桩的成桩设备，包括：劲芯钢管；外钢管支护，同轴设置在劲芯钢管的外侧；桩体开挖浇筑组件，底部可拆卸连接，包括：空气管道，沿轴线方向垂直贯穿桩体开挖浇筑组件，设置于劲芯钢管和外钢管支护之间；注浆通道，包括设置在透水层上方的第一注浆通道，以及设置在劲芯内层上方的第二注浆通道；抽浆通道，包括设置在透水层上方的第一抽浆通道，以及设置在劲芯内层上方的第二抽浆通道；通过设备对透水外壳及劲芯同时进行现浇施工形成劲芯复合排水桩，加快施工效率，能够极大的减少预制桩堆叠场地的使用，增加场地空间利用率；且使用挖孔的方式而非预制静压桩，不具有挤土效应，有利于施工的进行。
