Cost Reduction of Diaphragm Wall Excavation Using Air Foam

---

A novel stabilizing liquid using air foam rather thenbentonite clay slurry, i.e. air foam suspension, is employed in order to stabilize the trench wall suface during a diaphragm wall excavation. Air foam suspension is used to reduce the construction costs of working on an underground diaphragm wall. Airfoam suspension is created by mixing the excavated soil with air foam made from a suface-active chemical agent. The performance of air foam suspension depends on its density and consistency, that is, its table flow value (TF). By comparing the trench stabilization capacity of air foam suspension with that of bentonitecla slurry in model test, the appropriate performance of air suspension wasconfirmed.The cos evaluation of using an air foam suspension for a diaphragm wall excavation is presented.
