Zdl-150d Crawler-Type Deep Foundation Pit Anchoring Drilling Rig

Product Description

 

ZDL-150D tracked deep foundation pit anchoring drilling rig

The ZDL-150D tracked deep foundation pit anchoring drilling rig is an efficient drilling rig developed for anchoring, rotary spraying, and dewatering of domestic subways, high-rise buildings, airports, ground source heat pumps, and other deep foundation pits. Its main features are as follows:

1. The maximum speed can reach 170 rpm; which is 20% higher than the competitor's machine. It will be more effective for the use of Fried Dough Twists drills and soil layers.
2. Energy saving and efficient; Effectively improved work efficiency without increasing power
3. At the same time as the speed increased, the torque increased by 10% compared to MDL-135D, and the maximum turning torque increased to 7500NM
4. Adopting a new hydraulic system, the structure is simpler, the layout is more reasonable, and the operation is more user-friendly
5. The construction efficiency of MDL-135D drilling rig has increased by about 20% year-on-year
Torque and speed can be reasonably matched according to actual needs. The propulsion frame has a stroke of 3.4 meters and can be used for 3-meter drilling with drill rods and casing. Rotary devices with corresponding torque can be configured according to different geological formations, improving the adaptability of the drilling rig.
Equipped with a tracked chassis, a high-level rotating platform, a large-diameter leg oil cylinder, a 0.9-meter slide, and an orifice support device, the drilling rig is extremely convenient for displacement and positioning, and stable and reliable during drilling.
Equipped with a clamp and release device, it reduces labor intensity and increases efficiency when loading and unloading drill rods and casings.
We have developed corresponding drilling tools that can meet the following construction processes.
1. Three wing drill bit drilling, mud discharge. Suitable for high-speed drilling in soil and sand layers.
2. The air down the hole hammer drills in, and the air slag is discharged. Suitable for construction in rock formations and fractured layers.
3. Drilling with a hydraulic hammer at the bottom of the hole results in mud discharge. Suitable for construction in high water content strata such as fractured layers and sand egg layers.
4. Casing drilling
5. Drill pipe and casing composite drilling.
6. Single, double, triple rotary spraying, fixed spraying, swing spraying and other rotary spraying processes.
