Research and Application of New Backfill Materials Production from Engineering Mud
The paper took the new backfill materials application in the trench backfill project on Longyin Road in Xuhui District,Shanghai as a case study.The research team has determined the material performance indicators according to the engineering needs.Then,the backfill material mix ratio that meets both design and construction requirements was acquired through experimental research on the design of new backfill material mix proportion.A concrete mixing plant was used to produce high-fluid backfill materials,which were successfully filled in the trench on Longyin Road.The actual results show that the backfill material performance,construction efficiency and completion quality all satisfied or even exceeded expectations,achieved ideal demonstration application results.
