ST-200 Geological Drilling Rig Machine for Engineering Geological Exploration in Road and Railway Architecture
Borehole Drilling Rig Application:
ST-200 engineering drill is adopted with hydraulic pressure feeding structure, it can proceed attacking and gyrating drilling, and is used for engineering geological exploration in road,railway,bridge foundation,dam site,well,prospecting or industrial and civil architecture. It can also used in anchor rod engineering.

There are seven points for attention in the construction process of Borehole Drilling Rig
1. The operators of water well drilling rig shall be trained and qualified and take up the post with certificate.
2. The equipment entering the site shall meet the construction requirements, and the trial operation test shall be conducted before the formal start-up of the well drilling rig, and the operation status shall be stated in time.
3. The specific drilling process should be prepared, the operation rules and standards of water well drilling equipment should be prepared, and the construction records should be made.
4. During the drilling process, it is not allowed to rotate until the planned elevation is reached. Maybe if the drill pipe needs to be rotated or raised under special circumstances, the drill pipe should be lifted to the surface, and the bit valve should be dredged and closed from the beginning. The operator should strictly control the descent speed and rotation speed of the threaded bit.
5. Before drilling, carefully check whether the air hole at the top of the core pipe is smooth, whether the concrete delivery hose joint is outstanding, and whether there is distorted appearance.
6. In the process of hole forming, when the drill pipe is found shaking or the footage is slow, the footage should be slowed down to avoid pile hole deflection, displacement and damage of drill pipe and drilling tool.
