PROBLEM TO BE SOLVED: To provide a dewatering system of fine aggregate capable of dewatering a large quantity of fine aggregate quickly and inexpensively.SOLUTION: A dewatering system 1 includes a slope 10, a gravel layer 20 laminated on the slope 10, a water-permeable sheet 30 laminated on the gravel layer 20, a suction pipe 40 buried inside the gravel layer 20, extended approximately in the horizontal direction, and having a plurality of suction holes 44 formed thereon, and a suction device 50 for sucking through the suction pipe 40. According to this invention, fine aggregate can be dewatered more quickly in comparison with the case of only gravitational drainage by combining compulsive drainage with the gravitational drainage. Further, since the suction pipe 40 is arranged approximately in the horizontal direction, the suction device 50 can suck easily, and the suction device 50 is not required to be enlarged, to thereby achieve cost reduction. Furthermore, the fine aggregate is not required to be input into an apparatus as in the case of using a centrifugal dehydrator or a sealed container, to thereby enable dewatering from a large quantity of fine aggregate. |
