INSTALLATION OF IMPERMEABLE SHEET ON THE COASTAL WASTE DISPOSAL SITE BY MECHANICAL SHEET LAYING CONSTRUCTION METHOD

Abstract

Impermeable sheet (LLDPE, t =3mm or more) is used in constructing a controlled type coastal waste disposal site with riprap revetment or composite revetment. As a laying method with manpower saving, there is a mechanical sheet laying method, which was originally developed for laying sand prevent sheet. In this paper, this construction method is applied to laying of a impermeable sheet, and good construction results are obtained. In addition, we report the results of laying an impermeable sheet with a high penetration resistance protection mat placed on the lower surface.
