DRIVING METHOD FOR MULTIPURPOSE DRAIN

摘要

PROBLEM TO BE SOLVED: To form an anti-clogging multipurpose drain by which anti-liquefaction measure and consolidation acceleration of a soft viscous ground can be realized only by one drain. SOLUTION: A filter 3a using a knit fabric having a water permeability several times as much as sand or a woven fabric and a filter 3b using a continuous fiber nonwoven fabric made of a synthetic resin are laid at the surrounding of synthetic resin made cylindrical draining member in which cylindrical draining materials 2 that linear synthetic resin are overlapped in accordance with the variation of the earth layers of an objective ground or a number of holes are formed and by connecting them at an arbitrary length, one drain member 1 is formed. And an anti-liquefaction measure that the drain member 1 is placed in the ground and consolidation acceleration of a soft viscous ground are carried out. COPYRIGHT: (C)2004,JPO
