Concept of IPS system
IPS System stands for “Innovative Prestressed Support" system which uses tendons and short supports to replace conventional struts and wales.
Advantages of IPS system
- Reduced steel and labor
- Reduced costs of both earth retention and structure construction
- Reduced periods of both earth retention and structure construction
- Eco-friendly method of excellent steel recycling rate
- Reduction of ground deformation by prestress effect
- Safety increase via ductile flexural failure mode of IPS system
- Easy to excavate, to move soil out, to move materials in and to do all underground works
because of the wide open space of IPS system
