Drilling tool for reinforced concrete cast-in-situ bored pile
The invention discloses a drilling tool for a reinforced concrete cast-in-situ bored pile, and belongs to the field of building construction. Comprising a drilling machine mast, a telescopic drilling rod, a rotary excavating drill bit, a rectangular cutter and a telescopic cutter rod. The top end of the telescopic drill rod is connected to the drilling machine mast. The rotary excavating drill bit is arranged at the bottom end of the telescopic drill rod. The rectangular cutter is located above the rotary excavating drill bit, and a first drill rod hole allowing the telescopic drill rod to penetrate through is formed in the rectangular cutter. The bottom end of the telescopic cutter rod is connected with the rectangular cutter, and the top end of the telescopic cutter rod is connected with the horizontal restraining table which is provided with an impact device. The horizontal restraining table is located below the top end of the telescopic drill rod, and the telescopic drill rod penetrates through the horizontal restraining table and the impact device. Soil cutting and soil cutting are combined, the pile hole with the upper rectangular section and the lower round section is formed at a time in the construction process, the construction speed is increased, the defects that a drilling tool is replaced and the section is oversized in a traditional rectangular hole are overcome, and the pile hole is more suitable for being applied to underground space vertical components.
本发明公开了一种钢筋混凝土钻孔灌注桩的钻具，属于建筑施工领域。包括钻机桅杆、可伸缩钻杆、旋挖钻头、矩形切刀和可伸缩切刀杆。可伸缩钻杆顶端连接在钻机桅杆上，旋挖钻头设置在可伸缩钻杆底端；矩形切刀位于旋挖钻头上方，矩形切刀上设置有供可伸缩钻杆穿过的第一钻杆洞；可伸缩切刀杆底端与矩形切刀连接，顶端与水平约束台连接，水平约束台上设置有冲击装置；水平约束台位于可伸缩钻杆顶端下方，可伸缩钻杆穿过水平约束台和冲击装置。本发明将切土和挖土结合于一身，在施工过程中一次性形成上部矩形截面下部圆形截面的桩孔，提高了施工速度，克服了传统矩形孔更换钻具、截面超大的弊病，更适合地下空间竖向构件应用。
