Rotary excavating cast-in-situ bored pile structure and construction method thereof
The invention belongs to the technical field of rotary excavating cast-in-situ bored piles, and relates to a rotary excavating cast-in-situ bored pile structure which comprises a pile casing and a reinforcement cage, the pile casing is connected with a stabilizing assembly, the stabilizing assembly comprises a fixing frame arranged above a sleeve, a positioning plate is arranged on the fixing frame, and a driving assembly for driving the positioning plate is arranged on the fixing frame; a locking mechanism is arranged on the positioning plate, the locking mechanism comprises a plug pin and a sliding assembly arranged on the plug pin, and the sliding assembly comprises a sliding sleeve and a sliding rod; an elastic piece is arranged between the sliding rod and the sliding sleeve; slots are formed in the inner wall of the sleeve; the fixing frame is provided with a plug connector. The construction method comprises the following steps that the cast-in-place piles are positioned and arranged; embedding a pile casing; drilling and placing a reinforcement cage; a fixing frame is installed outside the pile casing, an adjusting plate is adjusted, and a motor is started to drive a positioning plate to abut against the top end of the reinforcement cage and enable bolts to be inserted into inserting grooves; pouring concrete; and the fixing frame and the pile casing are pulled out. The steel reinforcement cage has the effect of reducing the floating possibility of the steel reinforcement cage.
本申请属于旋挖钻孔灌注桩的技术领域，涉及一种旋挖钻孔灌注桩结构及，包括护筒和钢筋笼，所述护筒连接有用于稳固组件，稳固组件包括设置于套筒上方的固定架，固定架上设置有定位板，固定架上设置有驱动定位板的驱动组件；定位板上设置有锁定机构，锁定机构包括插销和设置于插销的滑移组件，滑移组件包括滑套和与滑杆；滑杆与滑套之间设置有弹性件；套筒内壁设置有插槽；固定架设置有插接件。其施工方法包括以下步骤：定位设置灌注桩；埋设护筒；钻孔并放置钢筋笼；在护筒外部安装固定架，调整调节板，启动电机驱动定位板抵押在钢筋笼顶端并使插销插入插槽；灌注混凝土；拔出固定架与护筒。本申请具有减小钢筋笼的上浮的可能性的效果。
