Example (b): as shown in fig. 1, the mechanical device for the low-clearance construction bidirectional extension rod stirring pile in the embodiment includes a concentric dual-shaft bidirectional stirring drill rod, which includes an outer drill rod 1 and an inner drill rod 2, wherein the outer drill rod 1 is sleeved on the periphery of the inner drill rod 2, and the outer drill rod 1 and the inner drill rod are concentrically arranged; in use, the outer drill rod 1 and the inner drill rod 2 can be respectively controlled by stirring power independently.
As shown in fig. 1, a segment of the concentric biaxial bidirectional stirring drill rod is shown, that is, the concentric biaxial bidirectional stirring drill rod for stirring pile construction adopts a segmented splicing structure, which can be formed by splicing a plurality of segments of the concentric biaxial bidirectional stirring drill rod.
Specifically, each section of the concentric biaxial bidirectional stirring drill rod section also comprises an outer drill rod 1 and an inner drill rod 2.
Wherein, the upper end of the outer drill rod 1 is provided with an outer female joint 3, and the lower end thereof is provided with an outer male joint 5. The outer male joint 5 and the outer female joint 3 are of a pair of adaptive thread structures, so that the outer drill rods 1 of two sections of mutually butted concentric double-shaft bidirectional stirring drill rod sections can be connected and fixed in a thread matching mode. Generally, an external thread is arranged on the outer side surface of the external male joint 5, and an internal thread matched with the external thread is arranged on the inner side surface of the external female joint 3, so that the connection between the external male joint 5 and the external female joint 3 can be realized through thread matching, and the fixation between two external drill rods 1 which are butted with each other can be further realized.
