SOME EXPERIMENTS WITH SAND-FILLED FLEXIBLE TUBES

Per Roed Jakobsen, Arne Hasle Nielsen

Abstract


Experiments with the use of long sand-filled flexible plastic tubes ("Sand sausages") have been carried out for coastal protection purposes at several exposed locations along the Danish coasts since 196T In general the results have been encouraging Several methods have been used to fill the tubes with sand A simple inexpensive hydraulic method for easy filling of almost impermeable tubes on site has been developed by model and prototype experiments with promising results As a result of the experiments it seems likely that sand-filled tubes may be used with advantage as temporary structures, 1 e for full-scale pilot investigations and to solve acute problems, or they may be incorporated in more permanent structures.
