Strong Capacity Crawler Intensity Geological Drilling Rig With Low Labor
Strong Capacity Crawler Intensity Geological Drilling Rig With Low Labor
Product Application:
1. ST-300 crawler drilling rig can be applied for different kinds of drilling technique methods and a variety of ground conditions. Especially in the difficult work condition, such as the incompact ground area, the gravel place, and the fragment rock stratum, this drilling can always provide the operator excellent solutions.
2. Geological drilling machine can be used for geological survey, basic exploration for road and high-rise building, the drilling of the inspection hole of various kinds of concrete structures, and subgrade grounting hole drilling and direst grounting. Geological drilling rig machine can also be taken for participating in the construction for dyke and dam of the river, civil well, ground temperature central air conditioning, etc.
3. ST-300 Drilling Rig has already been widely used in boring not only the Geotherm hole and water well or water exploration hole; but also the drain hole and large tonnage prestressed anchoring hole of the geotechnical engineering, such as boreholes on side slopes of dams, railways, highways, etc.; pipe sheds drilling of the underground engineering; the grouting reinforcing hole drilling; the small foundation pile boreholes; and the drilling holes of landslide preventing and the treatment engineering of rock collapse.
