WALKING TYPE THREE-AXIS CONTINUOUS WALL DRILLING RIG
SWWT85
SWWT85 WALKING TYPE THREE-AXIS CONTINUOUS WALL DRILLING RIG PRODUCT FEATURE
The sealing reliability of the power head grouting rotary joint has a direct impact on whether the power head can work normally. Because as long as the rotary joint has the leakage of cement slurry, then the cement slurry is very likely to enter the power box, causing excessive wear of bearings, oil seals, gears and other parts until complete damage.
SWWT85 Hydraulic static pile driver Performance Characteristics
1. Adopt three-axis drilling method, excellent drilling performance and high operating efficiency;
2. Special constant power motor is adopted, which has large starting torque, high insulation level and strong overload capacity;
3. It adopts high-strength structure design, compact structure, light weight, high guiding accuracy, strong stability of the whole machine, high groove accuracy, and the verticality of the underground continuous wall is below 0.5%;
4. No vibration, low noise, no mud pollution during the construction process, energy saving and environmental protection;
5. Adopt short drill bit structure, drill bit maintenance is more convenient;
6. Through the forced mixing of the drill pipe blades, the upper and lower walls of the continuous wall are uniform and the density is consistent, which is conducive to the improvement of wall strength and anti-seepage ability;
7. It can be equipped with a variety of operating chassis to meet the construction of multi-curve, small-radius dikes and ordinary foundations;
8. Large drilling capacity, ZLD 180/85-3-M 2 reinforcement depth up to 30m, ZLD180/85-3-M 2 groove thickness up to 850mm, ZLD110/65-3-M 2 groove thickness up to 650mm
