Designed for deep drilling and secant pile wall construction in soft muds, utilizing high-pressure clamping jaws.
Excellent cost-performance ratio. Ideal for drilling under complex conditions including sand layers and bedrock.
High-precision grab systems for metro line construction and deep basement retaining structures.
Highly efficient drilling platform optimized for groundwater development in Vietnam's central highlands.
Vietnam’s rapid industrialization and urban infrastructure boom—particularly in the Mekong River Delta, Red River Delta, and the major metropolitan areas of Ho Chi Minh City and Hanoi—present unique geotechnical obstacles. The geological profile of these regions is dominated by deep, soft alluvial clay, loose sand aquifers, and high hydrostatic groundwater tables.
Standard rotary drilling techniques utilizing bentonite slurry face severe risks of borehole collapse, skin friction loss, and environmental contamination. The integration of casing oscillators with heavy-duty rotary drilling rigs represents the safest and most efficient methodology.
By utilizing high-pressure hydraulic oscillation to press and twist steel casings deep into the ground ahead of the drill tool, operators can guarantee complete borehole integrity, control vertical drift tolerances within 1/200, and fully eliminate environmental hazards related to slurry management.
Strict noise and vibration regulations in Hanoi and HCMC make traditional impact-driving obsolete. Hydraulic oscillators run silently with negligible vibration.
Maintains safety and wall stability even when cutting through pressurized artesian sand layers common along the coastline and deltas.
Essential for secant pile walls for subway stations, where even a 1% deviation can lead to structural leakage and collapse.
Building strong foundations worldwide through specialized engineering machinery, comprehensive solutions, and premium logistics support.
Since the early 1990s, the core team of SINOVO has been at the forefront of pile construction machinery and geotechnical solutions. Today, we design, manufacture, and distribute dynamic equipment to more than 120 countries and regions.
In 2008, we executed a strategic market expansion, establishing TEG FAR EAST in Singapore to focus on the Southeast Asian market, specifically addressing the rapid development of infrastructure in Vietnam.
Our state-of-the-art manufacturing base, spanning over 7,800 square meters in the emerging industry zone, runs on advanced automated machinery. With ISO9001:2015, CE, and GOST certifications, our engineering systems ensure top-tier safety.

| Performance Metric | Full Casing (Oscillator Method) | Traditional Bentonite Slurry Drilling | Impact on Vietnam Projects |
|---|---|---|---|
| Borehole Safety | 100% mechanical stability; zero risk of cave-ins. | Relies on mud density; highly susceptible to layer collapse. | Essential in deep marine clay layers in Saigon. |
| Environmental Footprint | Clean operation, no mud disposal, zero soil contamination. | High slurry waste volume; disposal regulation compliance issues. | Important for downtown Hanoi metro projects. |
| Borehole Cleanliness | Perfect clean bottom; optimized concrete pouring quality. | High sediment buildup; risk of pile base weak spots. | Crucial for large-diameter bridges with heavy axial load. |
| Adjacent Structure Safety | Virtually zero ground settlement or lateral soil movement. | Risk of surrounding ground shifting or collapsing. | Protects adjacent structures in high-density urban zones. |
| Operating Cost | Higher initial equipment cost, but offset by lower logistics. | Expensive mud processing, disposal, and clean-up logistics. | Offers long-term economic gains on major worksites. |
How we solve engineering problems for bridge foundations, subways, and urban high-rise developments.
Secant pile wall installation is critical for basement excavations in water-retaining soils. SINOVO casing oscillators allow contractors to overlap primary and secondary concrete piles with millimeter precision, creating a continuous waterproof structural barrier.
For bridge foundations crossing the Mekong or Red River, our casing oscillators drive heavy-diameter steel tubes into unstable riverbeds, ensuring safe boring operations despite rapid water currents and moving sandbanks.
When encountering underground masonry, concrete wastes, or old structural elements during urban renewal projects, the high-torque cutting edge of the oscillator cuts through and removes obstacles directly.

For soft clays interbedded with sand layers in regions like the Mekong Delta, a hydraulic casing oscillator with a torque output of 1500 to 2200 kNm is recommended. This provides the force required to overcome high skin friction over deep casing lengths (30m to 50m) without locking up.
The oscillator connects directly to the rotary drilling rig via a specialized hydraulic adapter plate. The rig’s hydraulic system powers the clamping and oscillation cylinders. SINOVO supplies universal connection plates that work with both our TR series and other major global rig brands.
Yes, our casing oscillators are designed with high-power double-acting lift cylinders. They provide high pull-back forces, allowing temporary steel casings to be extracted during the concrete pouring process.
Standard machines have a lead time of 10 to 15 days from our manufacturing base. Due to our proximity to Tianjin Port, shipping to major Vietnamese ports like Haiphong or Cat Lai takes about 7 to 10 days. SINOVO Heavy Industry offers full customs clearance support.
