井戸掘削リグの使用において注意を払う必要があるいくつかの側面
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.井戸掘削リグの穴の底に、より多くの残留スラグが存在する場合があります。偏心ドリルビットの回転部分はスラグによってブロックされ、その収集生産に影響を与えます。このとき、圧縮空気を送り、穴を再度掃除する必要があります。、そして、ダウンザホールハンマーを短時間作動させてから、センタードリルのリフト操作を再開します。
