Water well drilling tools are suitable for water well drilling, geological survey, geological core drilling, small grouting holes, blasting holes for railways, water conservancy, bridges, dam foundations, and other buildings. Diamond, composite, and alloy drill bits can be used according to different formations. The drilling rig must master the operating requirements and comprehensive maintenance knowledge of the drilling rig, and have a wealth of troubleshooting experience. So, what water well drilling tools should be paid attention to in hydropower projects?

　　1 The safety of shipping water well drilling tools must be checked. All parts must be intact, and there must be no leakage of cables, drill pipes, drill bits, etc.

　　2 The drilling rig should be installed firmly, turning or bends, fixing the steel wire and fixing it;

　　3 When entering the construction site, the drilling rig should be fixed, the drilling area should be larger than the water well drilling tools, and there should be enough safe space around;

　　4 When drilling holes, construction must be carried out in strict accordance with the drilling position and direction, angle, hole depth, etc., and it is not allowed to modify the drill bit without authorization;

　　5 Check the drill rig when installing the drill pipe to make sure that the drill pipe is not stuck, bent, and the steel wire is not worn. Failure of drill pipe is strictly prohibited;

　　6 When loading and unloading the drill bit, strictly prevent the pipe clamp from clamping the cemented carbide parts, and strictly prohibit the flat drill bit and core tube.
