Description

Technical Field

[0001] The present application relates to the field of rotary drilling rigs, and in particular to a high-performance drill rod for rotary drilling rigs. Background Art

[0002] Rotary drilling is a construction technology suitable for hole-forming operations in building foundation projects. It is widely used in foundation construction projects such as municipal construction, highway bridges, and high-rise buildings. It is matched with different drilling tools and is suitable for dry short spiral, or wet rotary bucket and rock core drilling operations. When a conventional rotary drilling rig is used, the barrel drill bit with a valve at the bottom of the rod body is first used to rotate and crush the rock and soil, and directly load it into the drill bit. Then, the support rod lifting device at one end of the drilling machine and the telescopic drill rod will lift the drill bit out of the hole to unload the soil. This cycle is repeated, and the soil is continuously taken and unloaded until the designed depth is reached. For rock and soil layers with good adhesion, dry or clear water drilling technology can be used without mud wall protection. For loose and easily collapsed strata, or groundwater distribution, the hole wall is unstable, and a static mud wall protection drilling technology must be used to put wall protection mud or stabilizing liquid into the hole for wall protection.

[0003] With respect to the above-mentioned related technologies, the inventors believe that when a conventional rotary drilling rig is in use, the soil in some areas is relatively sticky, resulting in a lot of soil sticking to the drill bit and the surface of the drill rod after the drill bit is removed from the ground, thereby reducing the drilling efficiency during the secondary drilling.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
