UNDERGROUND WATER LEVEL LOWERING METHOD AND FACILITY LAYING SYSTEM FOR LOWERING UNDERGROUND WATER LEVEL
To provide an underground water level lowering method and a facility laying system for lowering an underground water level which easily lower an underground water level with less labor at lower cost.SOLUTION: An underground water level lowering method for lowering an underground water level in the ground includes: a step of performing guidance excavation so that a flexible rod 112 forming a bored hole H3 in ground G1 passes through a ground region deeper than an underground water level toward an arrival pit H2; a step of mounting a flexible drain pipe 120 composed of a cylindrical woven fabric through a connection member 130 on one end of the flexible rod 112; a step of pulling back the flexible rod 112, and thereby pulling the flexible drain pipe 120 to the bored hole H3 from the arrival pit H2, and laying the flexible drain pipe 120; a step of providing a drain port of underground water at the end of the flexible drain pipe 120 positioned at the arrival pit H2; and a step of collecting the underground water through the cylindrical woven fabric inside the flexible drain pipe 120 positioned deeper than the underground water level, and then flowing the underground water collected in the flexible drain pipe 120, and discharging the underground water from the drain port.SELECTED DRAWING: Figure 2
【課題】より少ない労力、コストで地下水位を容易に低下させる地下水位低下工法及び地下水位低下用設備敷設システムを提供する。【解決手段】地盤内の地下水位を低下させる地下水位低下工法において、地盤Ｇ１に削孔Ｈ３を形成する可撓性ロッド１１２を到達坑Ｈ２に向けて地下水位よりも深い地盤領域を通過するように誘導掘削を行う工程と、可撓性ロッド１１２の一端に連結部材１３０を介して筒状織布からなる可撓性排水管１２０を取り付ける工程と、可撓性ロッド１１２を引き戻すことによって、可撓性排水管１２０を到達坑Ｈ２から削孔Ｈ３に引き込んで敷設する工程と、到達坑Ｈ２に位置する可撓性排水管１２０の端部に地下水の排水口を設ける工程と、地下水位よりも深く位置する可撓性排水管１２０の内部に筒状織布を通じて地下水を集水してから、可撓性排水管１２０の管内に集水した地下水を流して排水口から排出する工程と、を有する。【選択図】図２
