Abstract
A method of constructing a barrier upon an underwater surface by storing sheet material as a rolled web, unrolling the web, continuously forming the web into a longitudinal hollow of a tube-like configuration, progressively positioning spaced longitudinal slot-defining edge portions defining the underside of the longitudinal hollow upon an underwater surface, thereafter delivering ballast material through and between the spaced edge portions into the longitudinal hollow and into overlying relationship upon the edge portions to hold the edge portions upon the underwater surface, and the ballast material being delivered through a portion of the longitudinal hollow as the web is unrolled but the longitudinal hollow is not yet positioned upon the underwater surface.
Claims13
A method of producing and laying on the ground an elongate structure consisting of at least one layer of flexible, tight and/or permeable and/or porous sheet material (13, 14, 16, 1), which forms at least one longitudinal hollow filled with sedimentary ballast material (19), characterized by a procedure comprising the following steps:
- unrolling from a roll (32) said sheet material in its longitudinal direction;
- advancing said roll in pace with the speed of said unrolling of said sheet material;
- shaping said sheet material into a tube-like configuration comprising at least one longitudinal hollow, in which the underside of said tube-like configuration is provided with at least one longitudinal opening allowing for passage of said sedimentary ballast material;
- laying the tube-like configured sheet material on the ground with the opening bottommost;
- and subsequently to forming the longitudinal opening filling said hollow with sedimentary ballast material through said opening in the underside of the unrolled, but not yet laid portion of said sheet material.
