Problems solved by technology

Since the drill pipe is not retractable, the height of the drill pipe body must be greater than the maximum drilling depth. At the same time, the height of the drill rig must be greater than the height of the drill pipe in order to match the drill pipe. Therefore, when drilling deep holes, the required height of the drill rig is high and the center of gravity is unstable. Prone to rig tipping accidents

Embodiment Construction

[0014] see Figure 1-Figure 4 , The embodiment of the present invention provides a drill pipe, including: a telescopic drill pipe body 6 , a drill bit 7 , a power head 3 and a grouting hose 2 . The power head 3 is connected to the top end of the telescopic drill rod body 6 , and the drill bit 7 is connected to the bottom end of the telescopic drill rod body 6 . The power head 3 drives the telescopic drill pipe body 6 to expand and contract in the up and down direction for drilling. One end of the grouting hose 2 passes through the telescopic drill pipe body 6 and is connected with the drill bit 7, and the other end is connected with the grouting device. The grouting hose 2 inside the telescopic drill pipe body 6 changes in length correspondingly with the extension or contraction of the telescopic drill pipe body 6 , and the grout is introduced from the grouting device to the drill bit 7 through the grouting hose 2 for grouting. The structure of the drill rod provided by the ...

Abstract

The invention relates to the technical field of building, in particular to a drill rod and a drill rig device. The drill rod comprises a telescopic drill rod body, a drill bit, a power head and a grouting hose. The power head is connected to the top end of the telescopic drill rod body, and the drill bit is connected to the bottom end of the telescopic drill rod body; the power head drives the telescopic drill rod body to extend and retract in the vertical direction to drill holes. One end of the grouting hose penetrates through the telescopic drill rod body to be connected with the drill bit, and the other end of the grouting hose is connected with a grouting device. The drill rig device comprises the drill rod, a drill rig column, a winding drum, a winding drum mounting rack and a trolley. The bottom end of the drill rig column is fixed onto the trolley, the winding drum mounting rack is fixed to the top end of the drill rig column, and the winding drum is mounted on the winding drum mounting rack. One end of the grouting hose is connected with the drill bit, the other end of the grouting hose is connected with the grouting device through the winding drum, and the grouting hose is laid on the winding drum. According to the drill rod and the drill rig device, the accident of rollover of the drill rig device is avoided, and meanwhile the working efficiency of grouting is improved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a drill pipe and a drill device. Background technique [0002] Rotary drilling rigs generally use multi-stage telescopic drill pipes, and the maximum drilling depth can generally reach 60-100m, which is suitable for bored piles with a diameter ≥ 600mm. Due to the use of telescopic drill pipes, the height of the drilling rig is generally set at 20-25m. The drill pipes take soil through the drill bit installed at the bottom of the drill pipes, and the drill pipes themselves do not have the grouting function. Since the drill pipe itself does not have the grouting function, the steel pipe is used for grouting after the drilling rig is completed. The steel pipe is segmented, and the length of each segment is 1-3m. Keep the bottom of the steel pipe 1~3m below the liquid level of the grout. Therefore, it is necessary to continuously measure the depth of grouting and dismantle the ...
