1. The anchoring engineering of water and electricity, mines, dams, and road embankments is mainly based on sled type lightweight hydraulic anchors and drilling machines. The anchoring engineering of mines is mainly based on rock anchors, which require high drilling accuracy. Generally, construction must be carried out on a scaffold about ten meters high. Therefore, it is necessary to ensure that the drilling machine is flexible and convenient to move on the scaffold, while also taking into acco

Rotary jet drilling rig (also known as rotary jet drilling tool): It is a drilling tool used to transport media such as slurry, compressed air, and clean water, and can ensure continuous dynamic and static tightness under high-pressure working conditions. Mainly composed of drill pipe, splitter, drill bit, anti loosening device, anti loosening device, fork and variable diameter joint. According to different drilling and usage methods, it can be divided into single rotary spraying, double rotary
