High-fill geology rotary excavating cast-in-situ bored pile construction device and construction method thereof
The invention discloses a high-fill geology rotary excavating cast-in-situ bored pile construction device and a construction method thereof. The construction device comprises a measuring assembly, the measuring assembly comprises a base plate, a large hanging bracket and a small hanging bracket are arranged on the base plate, the intersection point of the large hanging bracket and the small hanging bracket is opposite to the center point of the base plate, the large hanging bracket and the small hanging bracket are connected through a tape at the intersection point, and the exposed size of the tape is equal to the sum of the thickness of the base plate and the height of the large hanging bracket. The construction method comprises the following steps of pile hole paying-off and positioning, drilling of a drilling machine, embedding of a steel casing, hole forming, slag removal, sediment detection, hoisting of a reinforcement cage, selection and lowering of a guide pipe, concrete pouring and pulling of the casing. The method has the beneficial effects that the hole forming speed is high, and the project progress is guaranteed; the steel casing ensures the construction quality and can be repeatedly used; the underwater concrete pouring adaptability is high, the application range is wide, the construction speed is high, the construction period is shortened, the cost is saved, and the project quality is ensured.
本发明公开了一种高填方地质旋挖钻孔灌注桩施工装置及其施工方法。该施工装置包括测量组件，测量组件包括基板，基板上设有大吊架和小吊架，大吊架和小吊架的交叉点与基板的中心点相对，大吊架与小吊架之间通过交叉点处的皮尺连接，皮尺的漏出尺寸等于基板厚度和大吊架高度之和。该施工方法，包括如下步骤：桩孔放线定位、钻机钻孔、埋设钢护筒、成孔、清渣、沉渣检测、吊放钢筋笼、导管的选择及下放、混凝土浇筑、拔护筒。本发明的有益效果：成孔速度快，保证了工程的进度；钢护筒保证了施工质量，且可重复利用；导管灌注法水下混凝土浇筑适应性强，应用广泛，施工速度快，缩短施工周期、节约成本、确保工程质量。
