Long spiral drilling machine and construction method using same
The invention provides a long spiral drilling machine and a construction method using the long spiral drilling machine, and relates to the technical field of support piles, the long spiral drilling machine comprises a power head and a long spiral drilling rod, the long spiral drilling rod comprises a round steel cylinder, a long spiral blade, a long spiral mud injection steel pipe and an inner steel casing, the long spiral blade is spirally fixed on the outer side of the round steel cylinder, and the long spiral mud injection steel pipe is fixed on the inner steel casing. Corresponding to the long spiral blade, the long spiral mud injection steel pipe is spirally fixed at the root of the long spiral blade connected with the outer side of the round steel cylinder, and the screw pitch of the long spiral mud injection steel pipe is the same as that of the long spiral blade; the power head is connected with the round steel cylinder and used for driving the round steel cylinder to rotate and driving the long spiral blade to rotate. The round steel cylinder is of a hollow structure, the inner steel casing is embedded in the round steel cylinder, the top of the inner steel casing is detachably and fixedly connected with the round steel cylinder, and the inner steel casing is used for remaining underground to protect a pile core soil column.
本发明提供了一种长螺旋钻机以及用长螺旋钻机施工的方法，涉及支护桩技术领域，该长螺旋钻机包括动力头和长螺旋钻杆，长螺旋钻杆包括圆钢筒、长螺旋叶片、长螺旋泥浆注入钢管和内钢护筒，长螺旋叶片螺旋固定于圆钢筒的外侧，相应于长螺旋叶片，长螺旋泥浆注入钢管螺旋固定于长螺旋叶片与圆钢筒外侧相接的长螺旋叶片根部，长螺旋泥浆注入钢管的螺距与长螺旋叶片的螺距相同；动力头与圆钢筒连接，用于驱动圆钢筒转动并带动长螺旋叶片转动；圆钢筒为中空结构，内钢护筒嵌于圆钢筒内，内钢护筒的顶部与圆钢筒可拆卸的固定连接，用于留在地下保护桩芯土柱。
