Example 1:
as shown in fig. 1, in this embodiment, a drill bit device for pipe curtain construction includes a fixing rod 4, a guide rod 1 disposed at one end of the fixing rod 4, a plurality of rotating rods 2 hinged on the guide rod 1, a sliding sleeve 3 slidably disposed on the fixing rod 4, and an adjusting rod 9 hinged between the sliding sleeve 3 and the rotating rod 2.
During construction, the fixing rod 4 is connected with the jacking rotating equipment, the jacking rotating equipment drives the fixing rod 4 to rotate, the guide rod 1 is driven to rotate through the fixing rod 4, downward pressure is applied to the fixing rod 4 through the jacking rotating equipment, the guide rod 1 is made to rotate to enter the underground, and the rotary rod 2 on the guide rod 1 rotates to enter the underground to realize the drilling function.
The sliding sleeve 3 is controlled to slide on the fixed rod 4 through jacking rotating equipment, the angle of the rotating rod 2 can be adjusted as required, and therefore the effective range of the soil body damaged by the rotating rod 2 is adjusted. Destroy soil body, rock through the rotation of rotary rod 2, when rotary rod 2 descends to a certain position and need adjust the pore-forming diameter, utilize the top to advance rotary equipment control sliding sleeve 3 and remove, can realize the regulation of pore-forming diameter. The work of withdrawing the drill bit, replacing the drill bit and the like is not required, and the construction efficiency is improved.
In the drilling process, the guide rod 1 drills out small holes in advance to guide subsequent drilling, so that the drilling precision and efficiency are improved, and the drilling inclination is prevented.
Laser guiding device can be set up in guide bar 1 to this effect that can utilize laser to play the direction at the in-process of driling is favorable to improving the precision of driling. In this embodiment, it is prior art that the laser guiding device is used for drilling, and the specific structure and the theory of operation of laser guiding device do not make the improvement point of this scheme, and the specific structure and the theory of operation of laser guiding device are not prescribed a limit and repeated here.
Example 2:
on the basis of the above embodiment, in the present embodiment, the rotating rod 2 is provided with a plurality of external teeth 6. Utilize external tooth 6 to form the protruding structure of spaced, can improve the efficiency of rotary rod 2 broken rock to can the higher rock of crushing strength, thereby improve the efficiency of drilling.
In this embodiment, the external teeth 6 are conical or truncated cone-shaped. This can improve the sharpness of the external teeth 6, and can further improve the efficiency of crushing rock, and can realize a rock having higher crushing strength.
In the present embodiment, the external teeth 6 are screwed to the rotary rod 2. With this connection strength that can guarantee external tooth 6 and rotary rod 2 to can change after external tooth 6 consumes, damages, also can have more specific construction demand, change the external tooth 6 of different sizes, different shapes.
