High Strength Double Wall Casing Oscillator/Coupling For Drill Rig Machine
Unique hydraulic casing oscillator consists:
1. hydraulic casing oscillator, 2. power pack, 3. control system, 4. rotation motor, 5. casing twister,
6. casing drive, 7. single(double) walled casing 8. drilling bits.
Casing oscillator owns such merits as strong adaptability to geology, high quality of completed pile, low noise, no mud contamination, slight influence to former foundation, easy control, low cost, etc. It owns advantages in following geological conditions: instable layer, underground slip layer, underground river, rock formation, old pile, erratic boulder, quicksand, foundation of emergency and temporary building.
Application Range: Railway base, secant pile wall of deep foundation, pile extracting and clearance of the scrap pile for city reconstruction; Construction for port, bridge, river, lake, tower, hydropower, bored concrete pile, Batter pile, special purpose of bore pile. Casing construction suits for inner-city construction. It is especially suitable for coast, beach, old city wasteland, desert, mountain area and the place surrounded by buildings.
