초록
Coastal and fishing facilities are gradually deteriorating in function due to the continual accumulation of soil sediments, which has affected localeconomic activities. Currently, there are many methods to remove soil sediments, but these methods are either a temporary solution or require arepetitive removal of the soil sediments, which is a huge financial burden for the maintenance of the facilities. To solve these problems, this studyproposed a non-power soil cleaning system and evaluated field applicability by carrying out field model tests. The conditions for the evaluation focusedon the drainage-elapsed time and drainage-outflow velocity according to the water level change in the water tank. In the field test, silty clay and sandwere separately installed, and sedimentation soil removal test was practiced. As a result, the system was verified to have a sufficient outflow velocityfor the removal of soil sediments. In addition, a generalization equation that can be used in different regions of the tide was suggested in this study. These results will greatly contribute to removing soil sediments in ports and dike gate facilities on the southwest coast. Since the system is aneco-friendly technology that does not require additional energy, thus it is expected to contribute to maintenance of sustainable facility performance aswell as economic effect in the future.
