Description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is the A-A of Fig. 1 to sectional view.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment.
A kind of double waist hoop drill bit of cast-in-situ bored pile three wings with traction drilling rod, as shown in Figure 1 and Figure 2, including upper waist hoop 1, under
Waist hoop 2, wing plate 3, drilling rod 6 and traction bore 4, and the drilling rod is vertically arranged, and the drilling rod connects upper and lower coaxial by three wing plates
Spaced upper waist hoop and lower waist hoop, the wing plate be three, and uniform circular arrange, the upper waist hoop with diameter greater than under
The diameter of waist hoop, descends waist hoop diameter less by more than 1/3 than upper waist hoop diameter under normal circumstances, the upper surface of the wing plate and upper waist hoop
Upper surface flushes, and the lower surface of the wing plate is flushed with lower waist hoop lower surface, the lower surface 3B of the wing plate, the lower surface of lower waist hoop
And wing plate is fixedly mounted with spaced multiple brill teeth 5, each brill in lower waist hoop with the tilting section 3A that upper waist hoop transitioning end is formed
The end of tooth is inlaid with alloy；The bottom threaded coaxial of the drilling rod is connected with traction and bores, and the top that the traction is bored is formed with
