  • Cofferdam deformation-adaptive impervious structure and construction method of composite geomembrane
    Patent number: 9903082
    Abstract: The present invention relates to a cofferdam deformation-adaptive impervious composite geomembrane structure and construction method thereof, which applies mainly to high rockfill cofferdam, earth and rockfill dam and the like employing composite geomembranes for seepage control in hydraulic and hydro-power engineering. The cofferdam deformation-adaptive impervious composite geomembrane structure and construction method according to the present invention can reduce damage degree of the connections between the composite geomembranes and the concrete toe slabs or the joints between the composite geomembranes and the concrete caps on the top of the concrete impervious walls.
