Moving drill rod of cement-soil mixing pile driver
The invention belongs to the technical field of building equipment, and particularly relates to a moving drill rod of a cement-soil mixing pile driver. The moving drill rod solves the problem that existing cement-soil mixing pile drivers are prone to drill failures when drilling and the like, and comprises a driving box with an inner cavity, wherein the driving box is provided with at least one through hole which runs through the whole driving box in the axial direction; a guiding sleeve which can rotate in the circumferential direction and is cylindrical is arranged in the through hole; a drill rod which runs through the whole driving box is arranged in the guiding sleeve in a penetrating manner; an axial guiding structure is arranged between the drill rod and the guiding sleeve; the guiding sleeve is connected with a circumferential rotating mechanism which can drive the guiding sleeve to rotate in the circumferential direction; and the drill rod is connected with an axial driving mechanism which can drive the drill rod to slide back and forth in the axial direction. The moving drill rod of the cement-soil mixing pile driver has the advantages that a drill rod body can stretch in the axial direction, can rotate in the circumferential direction and slide in the axial direction at the same time, and thus is not prone to rotation failures; the perimeter of the cross section of a cement-soil mixing pile after constructing is increased; and the pull-out capacity of the cement-soil mixing pile is improved.
