1. After the drill bit of the water well drilling rig is drilled into the structure, the center drilling tool needs to be replaced in time. First, the bottom of the hole needs to be cleaned, and then the residue at the bottom of the hole is blown clean. The tool is slowly lifted upwards, and it is more appropriate when the lifting force is just enough to lift the drill tool.
2. The drill bit of the water well drilling rig is summarized during the drilling process. It is also necessary to pay careful attention to observe the follow-up situation of the casing, to understand the specific situation in the hole in time, and to keep the hole clean in time when necessary. During the process, strong lifting is prohibited.
3. Sometimes there will be more residual slag at the bottom of the hole of the water well drilling rig. The rotating part of the eccentric drill bit will be blocked by the slag, which will affect its gathering production. At this time, it is necessary to deliver compressed air and clean the hole again. , And make the down-the-hole hammer work for a short period of time, and then resume the lifting operation of the center drill.
