DTH Bit, as a kind of advanced piling machinery and equipment, is highly regarded for its efficient construction efficiency. It is widely used in the construction of pile foundations such as highways and bridges, high-rise buildings, and municipal engineering. Compared with traditional piling equipment, DTH Bit 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 Bit hard rock construction, the combination of pneumatic down-the-hole hammer drills and DTH Bit 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, which is an extremely suitable method for drilling holes in hard rock.
The DTH Hammer pneumatic DTH Hammer construction method uses a rotary drill as the main machine and hangs the DTH hammer drill tool; uses a high-power air compressor as a power source to provide high-pressure air; uses a pneumatic DTH hammer as a drill tool for impact drilling; The air returning from the bottom of the hole is used as the flushing medium, which not only provides impact power, but also has the functions of cooling the drill bit, cleaning the hole and removing slag.
