Key Features
Our Anti Floating Anchor Drilling Rig is not just a machine – it's a smart solution tailored to demanding site conditions.
The system detects resistance and automatically adjusts drilling speed and pressure, minimizing the risk of anchor movement during installation.
Hydraulic feed cylinder supports two-speed feed control, enabling operators to balance speed with torque efficiency.
Accommodates both top drive and casing pipe rotation, effectively preventing borehole collapse in unstable formations.
Tracked chassis with reinforced undercarriage ensures stability on uneven terrain, including slopes and soft ground.
Application Scenarios
The Anti Floating Anchor Drilling Rig is suitable for the following project types:
-
Subway and underground tunnel anchoring
-
Foundation pit support and slope protection
-
Dam and reservoir reinforcements
-
High-rise foundation engineering
-
Landslide mitigation projects
-
Anti-floating base construction for wetland or coastal structures
How It Works
The Anti Floating Anchor Drilling Rig works by using a high-torque rotating head and adjustable hydraulic feed to drill anchor holes at controlled depths and diameters. Once the borehole is completed, anchor rods or cables are inserted with a grout mix. The anti-floating system ensures the anchor stays stable during setting, resisting upward buoyancy forces often caused by groundwater or soil backpressure.
Advantages Over Conventional Drilling Rigs
| Feature | Conventional Rig | Anti Floating Anchor Drilling Rig |
|---|---|---|
| Uplift Resistance | Low | High |
| Depth Control Accuracy | Medium | High |
| Soil Compatibility | Limited | Wide (clay, gravel, sand, etc.) |
| Torque and Feed Control | Manual | Fully Hydraulic |
| Anchor Rod Stability | Risk of Floating | Fully Stabilized |
| Operator Learning Curve | Steep | Simplified Controls |
Common Questions (FAQ)
Q1: What makes an Anti Floating Anchor Drilling Rig different from a standard anchor rig?
A1: The Anti Floating Anchor Drilling Rig includes a built-in anti-uplift mechanism that stabilizes the anchor during installation. In standard rigs, ground pressure or groundwater may push the anchor upward, leading to failures. This rig counters that force actively.
Q2: Can this rig operate effectively in water-saturated soil or near rivers?
A2: Yes. The rig is specifically engineered for environments with high water content. Its hydraulic system and drill casing stabilize boreholes, while its anti-floating feature maintains anchor integrity even in buoyant soil layers.
Q3: How long does it take to train an operator to use this equipment efficiently?
A3: With our on-site support and simplified control system, a skilled technician can be trained to operate the Anti Floating Anchor Drilling Rig within 2–3 days. Its intuitive joystick controls and real-time pressure monitoring reduce the learning curve significantly.
Summary
The Anti Floating Anchor Drilling Rig is a robust, intelligent solution for complex anchoring challenges. With advanced hydraulic systems, adaptive control, and a strong anti-floating mechanism, it has become a key choice for construction companies around the world dealing with difficult soil conditions and uplift risks.
