<p>A method and apparatus for producing and laying a ballasted mat (15) for ground stabilization. Fields of application of the invention include prevention of scour along submarine pipelines (1) shore and river bank protection, prevention of siltation in waterways, construction of submarine barriers, road construction. The mat (15) consists of two sheets (2, 30 or 31) and is formed by continuously seaming the two sheets together in parallel lines. Simultaneously the tube-like compartments thus formed between the two sheets are continuously being filled with particulate ballast material (3). Gravity is utilized for ensuring complete filling of the compartments and for continuous reeling off of sheet material (2) in pace with the continuous advancement of the mat-forming machine (16) over the ground to be covered with the mat (15). </p> |
