The retaining wall piece comprises arc, support plate and block;
Puddler comprises the body of rod and pole socket;
It is characterized in that:
Said block is arranged in the outer wall that is positioned at the body of rod under the socket along the hollow rods radial symmetric, and the intrados welding of said support plate and arc is fixing, and they are installed in the seat groove of block through said support plate (22) with bearing pin then;
Said puddler has many groups; And be positioned on the following body of rod diverse location of retaining wall piece; Each group puddler comprises a pair of or two pairs of puddlers of arranging along the hollow rods radial symmetric, and each puddler comprises a body of rod and a pole socket, wherein; Pole socket is fixedly welded on the outer wall of the body of rod of hollow rods, and the body of rod is installed in the groove of pole socket with bearing pin;
The utility model can be that said retaining wall number of blocks is 2,4 or 6, arranges along the body of rod radial symmetric of hollow rods.
The utility model can also be that the body of rod in said many group puddlers between neighbouring one group of puddler is that arrangement is arranged in dislocation at the body of rod along hollow drill pipe in the radial direction.
The utility model can also be that said retaining wall piece and the puddler free end rotating diameter when rotating with hollow drill pipe equates.
The utility model drilling rod has following good effect and advantage:
1, according to the utility model; When rig bores the pick operation downwards; The retaining wall piece that is arranged in the body of rod outer wall that is positioned under the hollow rods socket along the hollow rods radial symmetric can effectively be protected the hole wall that bores pick formation; Reduction is because of the situation that landslide causes construction safety to guarantee, the hole quality of the inwall of guaranteeing to hole effectively improves bore operation efficient.
2, according to the utility model, be arranged symmetrically on the body of rod of hollow rods the retaining wall piece with stir piece and adopt the detachable structure, simple in structure, easy to make, low cost of manufacture, job failure are low.
