SOFT GROUND IMPROVEMENT SYSTEM, CONNECTION MEMBER, AND SOFT GROUND IMPROVEMENT METHOD
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
【課題】フィルタの目詰まりによる真空度の低下、フィルタの新品交換などによる無駄をなくすことが可能な軟弱地盤改良システム、接続部材および軟弱地盤改良方法を提供する。【解決手段】真空圧密を適用する改良地盤１に密封シート２０を被覆して周辺部から隔離し、その密封シート２０の下に打設された複数の鉛直ドレーン１０、および、その鉛直ドレーン１０と地表近傍で通水可能に係合された水平ドレーン５０に対し、真空ポンプ３０の負圧を付与して減圧領域を形成するとともに、負圧を付与する経路をたどって減圧領域から排水することにより改良地盤１を改良する軟弱地盤改良システム１００であって、負圧を付与する経路は真空ポンプ３０から無孔管４０、水平ドレーン５０および鉛直ドレーン１０の順番であり、無孔管４０と水平ドレーン５０とは双方の接続部における負圧の低下を最小限にする接続形態である。【選択図】図１
