Cyclic drilling machine with function of hydraulic hole expansion and construction method for hole-expanded pile
The invention discloses a cyclic drilling machine with a function of hydraulic hole expansion and a construction method for a hole-expanded pile. The cyclic drilling machine with the function of hydraulic hole expansion comprises a fixed frame, a cross beam, a power device, a drilling rod, a connection head, a drilling bit, a lantern ring, an expansion rod, a hydraulic device and drilling teeth, wherein the drilling rod can be lengthened through mutual connection of flange discs; a part located on a slide path of the lantern ring, of the lower end of the drilling rod, is of a square structure;and the inner side of the lantern ring and the lower end of the drilling rod are the same in shape. According to the cyclic drilling machine with the function of hydraulic hole expansion and the construction method for the hole-expanded pile, a stable and reliable hole expansion effect and high efficiency are achieved; cyclic hole cleaning for mud can be carried out during hole expansion, and sediments in an expanded cavity are avoided; and the cyclic drilling machine with the function of hydraulic hole expansion is high in hole expansion quality and suitable for being popularized and used.
本发明公开了一种液压扩孔循环钻机及其扩孔桩施工方法，包括固定架、横梁、动力装置、钻杆、连接头、钻头、套环、扩张杆、液压装置和钻孔齿，所述钻杆可通过法兰盘相互之间连接进行加长，所述钻杆的下端，位于套环滑动的线路上的钻杆为方形结构，所述套环的内侧形状和钻杆的下端形状相同，本发明的有益效果是：该一种液压扩孔循环钻机及其扩孔桩施工方法，扩孔作用稳定、可靠，效率高，扩孔时可以进行泥浆循环清孔，扩大腔内无沉渣，扩孔质量好，适合推广使用。
