Earth dam with underground and antinuclear sealing - contg. earth concrete wall and polyamide and/or polyester filter web (BR 24.8.76)

摘要

A heaped earth dam provided with an underground sealing and an adjoining anti-nuclear sealing device contains at least one louvered slide (I) which contains or consists of concrete. A filter web is provided between (I) and supporting body on side of air. Filter web contains a filter mat. Coarse-fibred, rough plastic material is needled, or otherwise applied, to both sides of this filter mat. Use of earth concrete in louvered slide, allows it to bear high deformation without cracking. Cracks heal automatically, without further damage. Coarse filter web fibres prevent clogging. Earth concrete consists of materials having properties similar to those of earth dam itself, i.e. rigidity moduli have same order of magnitude.
