CONSTRUCTION METHOD AND APPARATUS FOR DEHYDRATING SOFT GROUND BY USING DRAIN WITH FIBER

摘要

PURPOSE: A method for dehydrating soft ground and product thereof are provided to prevent deformation of a hollow board drain by attaching nonwoven fabric on a body of the board drain despite sinking a ground and to dehydrate by maintaining safe state. CONSTITUTION: A hollow board drain(1) attaching a nonwoven fabric(3) forms a vertical dehydrate passage(10) with a vertical compartment by covering the nonwoven fabric around a hollow board drain body(2). The nonwoven fabric forms a nonwoven fabric weaving face(12) weaving short fabric nonwoven textile expanded from an external face and short fabric nonwoven textile expanded from an internal face. Thereby, an external face of the nonwoven fabric is the expanded short fabric nonwoven textile. Moreover, an internal face of the nonwoven fabric contains an even surface to actively drain by maintaining equal state without tangling.
