(TU Delft Geo-engineering; Gemeente Rotterdam) van Tol, A.F. (TU Delft Geo-engineering; Deltares) Broere, W. (TU Delft Geo-engineering) Doornenbal, Pieter (Deltares) Hopman, Victor (Deltares) Date 2017 Abstract Distributed temperature sensing (DTS) can be used to monitor the production process of diaphragm walls. DTS is able to differentiate between already present or fresh bentonite suspensions during refreshing of the bentonite slurry in the trench. During concrete casting, DTS is able to differentiate between the bentonite suspension and concrete. As a result, the continuity of the casting process and the arrival of good grade concrete at crucial locations in the trench can be monitored. Tests conducted on laboratory models provided reference information for interpretation of field data. Field experiences have shown the benefits of DTS tests and the predictive value of the reference measurements. Results are compared with crosshole sonic logging measurements at the same location.
