Bachy Soletanche Vietnam is proud to share its technical article featured in Issue No. 8 of the Vietnam Society for Soil Mechanics and Geotechnical Engineering (VSSMGE) Bulletin—a respected publication in the field of geotechnical and underground construction engineering.
🧱 Article Title:
“Circular Diaphragm Wall in Underground Construction and Its Application at the Inlet Pumping Stations of the Wastewater Treatment Plant Project”
The article was developed by the Technical Department of Bachy Soletanche Vietnam, combining on-site construction experience with in-depth engineering analysis.
Key Highlights:
A diaphragm wall is a continuous reinforced concrete retaining structure widely used in underground construction such as:
-
High-rise building basements
-
Underground stations
-
Cut-and-cover tunnels
-
Deep shafts
This method is particularly effective for excavations deeper than 25 meters, providing multiple advantages:
-
High excavation stability
-
Prevention of ground collapse and effective groundwater control
-
Minimal wall deformation and ground settlement
-
Enhanced safety for workers and adjacent structures
Among diaphragm wall types, the circular diaphragm wall stands out as a highly optimized solution:
-
Requires no internal bracing
-
Delivers extremely low deformation
-
Reduces construction time and costs
-
Performs exceptionally well in deep excavations and complex geotechnical conditions
Case Study Highlight:
This solution was successfully applied in a 47-meter-deep, 21.8-meter-diameter circular shaft at the inlet pumping station of a wastewater treatment plant.
Field performance demonstrated outstanding results in terms of:
-
Excavation stability
-
Deformation control
-
Practical constructability
Technical Contribution
This innovative solution not only improves construction safety and efficiency but also reflects the technical expertise and hands-on capability of Bachy Soletanche Vietnam in delivering sustainable infrastructure for underground works.
Being featured in this VSSMGE publication reinforces BSV’s leadership and long-standing experience in foundation engineering and deep excavation systems.
