PROBLEM TO BE SOLVED: To provide a soft ground improvement system which can eliminate a decline in the degree of vacuum due to clogging of a filter and a loss in time and work because of replacement of the filter with a new one; a connection member; and a soft ground improvement method.SOLUTION: In a soft ground improvement system 100, a ground 1 to be improved to which vacuum consolidation is applied is covered with a sealing sheet 20 so as to be separated from a peripheral part, and negative pressure of a vacuum pump 30 is applied to a plurality of vertical drains 10 installed under the sealing sheet 20 and a horizontal drain 50 engaged with the vertical drains 10 in a water conduction state in the neighborhood of a surface so as to create a pressure-reduced region while water is discharged from the pressure-reduced region by taking a route through which negative pressure is applied, so that the ground 1 to be improved is improved. The route through which negative pressure is applied is from the vacuum pump 30 through a non-hole pipe 40 and the horizontal drain 50 to the vertical drains 10 in this order, and the non-hole pipe 40 and the horizontal drain 50 are connected so as to minimize a decline of negative pressure in both connection parts.SELECTED DRAWING: Figure 1
