The SEMW MS Series Cutter Soil Mixing Machine is designed for cutter soil mixing (CSM) construction in urban foundation engineering,
seepage cut-off walls, excavation support, and deep ground improvement projects. Combining milling technology with in-situ mixing,
the MS Series helps contractors build high-quality soil-cement walls with strong adaptability to complex strata and confined sites.
With both step-type and crawler-type configurations, the series supports a wide range of construction needs where wall quality,
vertical accuracy, efficient power transmission, and intelligent process monitoring are critical.
The MS Series is developed for the CSM (Cutter Soil Mixing) method, which combines trench cutting and deep soil mixing to create soil-cement wall structures.
This construction method is especially suitable for projects requiring reliable wall continuity, controlled alignment, and strong adaptability to changing geological conditions.
The MS Series is engineered to balance wall-forming capability, operating efficiency, and project adaptability. The following advantages are especially relevant for owners,
contractors, and engineering teams evaluating CSM equipment for long-duration urban or infrastructure works.
Adopts variable-frequency speed-regulating motor direct drive for high transmission efficiency, lower operating cost, and responsive speed control.
Provides up to 100,000 N·m torque to support cutter soil mixing operations in demanding formations and deeper wall construction tasks.
Independent control of the mixing heads improves adaptability in complex ground conditions and supports more flexible construction adjustment.
Available in step-type and crawler-type versions, allowing contractors to choose the most appropriate platform according to site logistics and work style.
The series covers wall forming depth up to 55 m and wall thickness from 700 mm to 1200 mm, meeting a wide range of project requirements.
Especially applicable where formation levels vary significantly, turning points are frequent, and surrounding structures require controlled construction impact.
The table below compares the main performance parameters of the three available MS Series configurations.
It provides a clear starting point for model comparison and preliminary technical selection.

Beyond mechanical capability, the MS Series supports digital process control to help project teams manage slurry performance, wall quality, and execution data more efficiently.
The following site images show the MS Series working in real foundation construction environments, including city-center excavation support and deep soil mixing projects.
Demonstrates suitability for dense urban jobsites where deep excavation work requires controlled wall construction and careful logistics planning.
Well suited for large excavation areas where soil-cement wall continuity and depth control are essential to project safety and progress.
Supports ground improvement and retaining wall construction in high-traffic commercial areas where space efficiency matters.
Shows the machine operating on a broad construction site where deep mixing work integrates with large-scale foundation and infrastructure activity.
SEMW focuses on foundation construction machinery and integrated engineering solutions. The company has built long-term product expertise across piling, mixing, trenching,
vibro, and specialized underground construction equipment categories.
The MS Series is designed for the CSM method, integrating trench cutting and in-situ mixing. This allows the machine to build soil-cement walls with strong wall-forming capability, making it especially useful for cut-off walls, retaining walls, and reinforcement works in complex ground conditions.
For projects demanding larger wall thickness and deeper construction, the MS55E is the stronger option within the series. For many standard CSM projects, the MS45E step-type or crawler-type configuration can also provide a practical solution depending on site conditions.
Yes. The MS Series is particularly suitable for urban excavation support, waterproof walls, and ground improvement where alignment changes, tight access, or surrounding building sensitivity require controlled construction performance.
Yes. SEMW can support preliminary model recommendation according to wall depth, wall thickness, geological conditions, project output target, and site access requirements.
