Backfilling Using Fluidized Soil-Cement Mixture Made With Excavated Soil Containing Old Fly Ash
In the replacement project of the Taketoyo Thermal Power Plant in Aichi prefecture Japan, surplus soils generated from excavation works and sand compaction pile installations were used as a base material of the fluidized soil-cement mixture for infill works of old underground structures. In a planning stage, physical properties of the surplus soils and the fluidized soil-cement mixtures were investigated in order to establish a handling method of the variable surplus soils obtained from the extensive construction area. The results showed 1) the surplus soils could be recognized as a mixture of backfilled sand and old fly ash, 2) required properties of the fluidized soil-cement mixture could be achieved by putting cement 70 kg/m3 and securing proper content ratio of sand and fly ash. With these findings, a production control plan was prepared for the actual work using an on-site batching plant system. As a result of execution of the proper material handling, 9,000 m3 of fluidized soil-cement mixture were successfully used for infill works.
