DISCHARGE STRUCTURE FOR GROUNDWATER AND CONSTRUCTION METHOD FOR DISCHARGE STRUCTURE FOR GROUNDWATER

摘要

PROBLEM TO BE SOLVED: To provide a novel discharge structure for groundwater that can prevent a liquefaction phenomenon by discharging groundwater in the ground more effectively and lowering the groundwater level, and a construction method for the discharge structure for groundwater that is used to construct the discharge structure for groundwater.;SOLUTION: A lateral conduit 1 formed of a lateral conduit formation material in the ground, a pit 3 to which ground water flowing in the lateral conduit 1 is discharged, discharge means 4 of discharging the ground water discharged into the pit 3, and a longitudinal conduit 5 formed of a longitudinal conduit formation material made of a plurality of longitudinal drain materials are arranged in the ground. The groundwater in the ground flows directly into the lateral conduit 1 also flows in the lateral conduit 1 through respective longitudinal conduit formation materials, and is then discharged from the pit 3 by the discharge means 4 after flowing in the pit.;COPYRIGHT: (C)2015,JPO&INPIT
