  1. After the drill bit of the   hydraulic water well drilling rig   is drilled into the structure, the center drilling tool needs to be replaced in time. First, you need to clean the bottom of the hole, and then blow away the residue at the bottom of the hole. After the bit stops rotating, drill the bit on the hydraulic water well drilling rig. It is most suitable for slowly increasing the lifting force, which can just lift the drill bit. 2. Summarize the drilling process of the hydraulic water well drilling rig. It is also necessary to pay close attention to the subsequent working conditions of the casing, to understand the specific situation of the wellbore in time, to clean up the borehole in time, and to drill the bit on the water well drilling rig. During this process, it is strictly forbidden to hoist. 3. At the bottom of the hydraulic water well drilling rig, there will be more residues. The eccentric drill bit will be stuck by the slag, which affects the collection and produc

  A down-the-hole drill, usually called   DTH Drilling Rig , is basically a mini jackhammer screwed on the bottom of a drill string. The speedy hammer activity breaks hard stone into little flakes and dust and can be dismissed evident by the air exhaust in the DTH hammer. Considering that the DTH method was initially designed to drill large-diameter holes in surface-drilling software, its title originated in the fact that the percussion mechanism adopted down the bit to the gap. Programs were afterward discovered for the DTH process underground, in which the management of drilling is usually upwards rather than downwards. DTH didn't need hefty down thrusts or large rotational levels and as such a mild, cheap machine may be utilized to execute the drilling procedure - the system might also be operated by a single individual, whereas other systems demanded two operatives. The advantages that  DTH Well Drilling Rigs  attracted to the sector were so tremendous - for the very first time
