Segmented lowering steel casing for cast-in-situ bored pile construction
The invention discloses a segmented lowering steel casing for cast-in-situ bored pile construction. The segmented lowering steel casing comprises an upper steel casing body, a lower steel casing body and a plurality of connecting clamping plate assemblies for connecting the upper steel casing body with the lower steel casing body; a top stiffening plate is arranged on the upper portion of the upper steel casing body; a hoisting hole is formed in the top stiffening plate and the upper steel casing body in a penetrating mode; each connecting clamping plate assembly comprises a section of arc-shaped inner side stiffening plate welded to the inner wall of the bottom end of the upper steel casing body, a section of arc-shaped outer side stiffening plate welded to the outer wall of the bottom end of the upper steel casing body and corresponding to the inner side stiffening plate, and a plurality of vertical stiffening ribs welded to the outer side of the outer side stiffening plate; and the bottom faces of the inner side stiffening plates and the bottom faces of the outer side stiffening plates protrude out of the bottom end of the upper steel casing body, so that gaps are formed between the inner side stiffening plates and the outer side stiffening plates, and the upper portion of the lower steel casing body is just inserted into the gaps. The operation is easy, the upper steel casing body and the lower steel casing body are convenient to detach, the upper steel casing body with the upper portion capable of being pulled out can be recycled, operability is high, the popularization range is wide, and the construction cost is low.
本发明公开了一种用于钻孔灌注桩施工的分节下放钢护筒，包括上部钢护筒、下部钢护筒、连接上下部钢护筒的多个连接卡板组件，在上部钢护筒上部设置顶部加劲板，穿过顶部加劲板和上部钢护筒设置有吊装孔，连接卡板组件包括焊接在上部钢护筒底端内壁的一段弧形内侧加劲板、与内侧加劲板相对应焊接在上部钢护筒底端外壁的一段弧形外侧加劲板、外侧加劲板的外侧焊接有多个竖向的加劲肋，内侧加劲板和外侧加劲板的底面凸出上部钢护筒底端，使内侧加劲板和外侧加劲板之间形成的空隙，正好使下部钢护筒的上部插入其中。操作简单，上下钢护筒拆卸方便，上部可拔除的上部钢护筒可以重复循环利用，操作性强、推广范围大，施工成本低。
