Problems solved by technology

[0003] However, in the construction of concrete pouring pile rotary drilling and drilling, the phenomenon of "deviation of the hole" is prone to occur. The traditional technology adopts backfilling and re-opening the hole. The method is single, wastes a lot of resources, and cannot guarantee the quality of the pile foundation. During construction and pouring Reinforcement relocation affects the construction of the lower part

Abstract

The invention provides a novel auger bit and a using method thereof. The novel auger bit structurally comprises a drill body, and the shape of the drill body is a cylindrical body with the bottom being provided with a cone angle; helical blades surrounds the exterior of the drill body in the circumferential direction, and clamping grooves are formed in the helical blades; movable drill teeth are arranged in the clamping grooves and comprise extending parts and connecting parts, the connecting parts are arranged at the root positions of the extending parts, and the connecting parts are movablyconnected to the interiors of the helical blades; a central fixing rod is arranged in the drill body, and a hydraulic power device is connected to the central fixing rod; the bottom of the hydraulic power device is provided with movable connecting rods, and the movable connecting rods are connected with the movable drill teeth. The problems that after the phenomenon of hole position shifting occurs during construction, a hole is formed again after backfilling according to a traditional technology, the method is single, a large number of resources are wasted, and the pile foundation quality cannot be guaranteed are solved.

Description

technical field [0001] The invention belongs to the field of engineering construction, in particular to a novel helical drill bit and a using method thereof. Background technique [0002] In the construction of large-diameter concrete pouring piles abroad, rotary drilling rigs generally account for more than 2 / 3. Due to its high installed power, large output torque, large axial pressure, flexible maneuverability, high construction efficiency, and environmental protection, the rotary drilling rig is suitable for drilling holes in most areas of my country with different drill bits. The ideal construction machine for the job. In general, the most commonly used are short auger bits and rotary drilling buckets. [0003] However, in the construction of concrete pouring pile rotary drilling and drilling, the phenomenon of "deviation of the hole" is prone to occur. The traditional technology adopts backfilling and re-opening the hole. The method is single, wastes a lot of resources...
