Application Range
QDGL-2B anchor drilling rig is used for urban construction, mining and multiple purpose, including side slope support bolt to deep foundation, motorway, railway, reservoir and dam construction. To consolidate underground tunnel, casting, pipe roof construction, and pre-stress force construction to large scale bridge. Replace foundation for ancient building. Work for mine exploding hole.
Main Features
1. Full hydraulic control, easy to operate, easy to move, good mobility, time-saving and labor-saving.
2. The rotary device of the drilling rig is driven by double hydraulic motors with large output torque, which improves the drilling stability of the drilling rig.
3. It can be equipped with a new angle changing mechanism to make the hole more convenient and the adjustment range larger, which can reduce the requirements of the working face.
4. The cooling system is optimized to ensure the working temperature of the hydraulic system is between 45 and 70 ℃ ° between.
5. It is equipped with a pipe following drilling tool, which is used to protect the wall of casing in unstable formation, and the conventional ball tooth bit is used to finish the hole. High drilling efficiency and good hole forming quality.
6. In addition to the crawler chassis, clamping shackle and rotary table, the rotary jet module can be selected to make the rig more suitable for engineering construction.
7. Main drilling methods: DTH hammer conventional drilling, spiral drilling, drill pipe drilling, casing drilling, drill pipe casing compound drilling.
