A VACUUM PRESSURE TIGHENING AND DEHYDRATION QUICKENING CONSTRUCTION WORK METHOD FOR THE GROUND TO DISCHARGE DREDGE SOIL USING THE HOLLOW BOARD DRAIN WITH THE NON-WOVEN CLOTH ATTACHED AND THE GOODS

摘要

PURPOSE: A method for performing a vacuum pressure dehydrating at dredged soil throwing place is provided to improve the ground by enhancing the dehydrating function due to the improvement of vacuum pressure dehydrating technique, and to smoothly perform a forced pressure dehydrating function without generating a shearing phenomenon. CONSTITUTION: In the method for performing a vacuum pressure dehydrating at dredged soil throwing place, the dredged soil throwing place is formed at a position spaced from the sea by means of a bank structure. A plurality of hollow board drains(7) having non-wovens attached thereto are installed in the dredged soil throwing place by means of a water collective pipe having a vacuum pump therein, a sealed pipe and a plurality of weights according to the horizontal drain technique. A dredged soil construction is formed by pouring the dredged soil onto the hollow board drains(7). At this time, the weights are engaged with each other by means of a string and are disposed in the dredged soil construction.
