Concrete pouring construction device and method for bored pile crossing karst cave section
The invention provides the concrete pouring construction device and the concrete pouring construction method for the karst cave crossing section of the bored pile, which are good in cave sealing effect. The concrete pouring construction device comprises a concrete pile casing, a reinforcement cage and a hoisting mechanism, the supporting table is connected with the reinforcement cage; the concrete pile casing is arranged above the supporting table and is formed by pouring concrete and a supporting ring, the supporting ring is located at the bottom of the concrete pile casing, and a plurality of connecting rods are evenly distributed in the circumferential direction; the hoisting mechanism comprises a shell, a telescopic rod, a hoisting hook and a power unit; one end of the telescopic rod can be inserted into the supporting ring, and the other end penetrates through the shell to be provided with a power unit which controls the telescopic rod to stretch out and draw back. The concrete pouring construction method comprises the following steps that the construction position of a pile foundation is determined, and drilling is conducted; lowering a reinforcement cage in sections; the concrete pile casing is installed at the designated position of the reinforcement cage; the hoisting mechanism is lifted to install a reinforcement cage; the reinforcement cage continues to be installed to the pile top; and concrete is poured to the pile top.
本发明提供了一种“封洞”效果好的钻孔桩穿越溶洞段的混凝土灌注施工装置和施工方法。混凝土灌注施工装置，包括砼护筒、钢筋笼和吊装机构；支撑台与钢筋笼连接；砼护筒，设置在支撑台上方，采用混凝土和支撑环浇筑而成，支撑环位于砼护筒底部，沿圆周方向均布多个连接杆；吊装机构包括壳体、伸缩杆、吊钩和动力单元；伸缩杆一端能够插接在支撑环上，另一端穿过壳体设置动力单元，动力单元控制伸缩杆伸缩运动。混凝土灌注施工方法，包括以下几个步骤：确定桩基的施工位置钻孔；分节下放钢筋笼；将砼护筒安装在钢筋笼上的指定位置；提拉吊装机构进行钢筋笼的安装；继续安装钢筋笼直至桩顶；灌注混凝土至桩顶完成。
