Top Hammer Drilling Tools, as an advanced piling machinery and equipment, is highly respected for its efficient construction efficiency. It is widely used in the construction of highway bridges, high-rise buildings, municipal engineering and other pile foundation construction fields. Compared with traditional piling equipment, DTH Drill Pipe has significant advantages in all types of rock and soil construction. However, there is also a problem of low construction efficiency when drilling into hard and extremely hard rock formations.
In order to improve the status quo of DTH Drill Pipe hard rock construction, the combination of pneumatic down-the-hole hammer drills and DTH Drill Pipe is an extremely effective solution. Pneumatic down-the-hole hammer is a drilling tool that generates impact force with an air-driven impactor. Due to the short time of impact force and large impact force, it can effectively break hard rock formations, quickly form holes, and impact The drilling method has relatively little wear on the drill bit, and is a very suitable method for drilling holes in hard rock.
The construction method of DTH Drill Pipe is to use rotary drilling as the main machine and suspend down-the-hole hammer drill tools; use high-power air compressor as the power source to provide high-pressure air; use pneumatic down-the-hole hammer as the drilling tool for percussion drilling; The upper return air is used as a flushing medium, which not only provides impact power, but also has the functions of cooling the drill bit and cleaning holes and slagging.
