Abstract
A continuous linear element is used in the form of a fine fibrous trap, delivered in a continuous manner by an ejector (11) placed in a gaseous atmosphere established in an open-bottomed bell (8) immersed in the liquid medium with its open bottom close to the deposition site of the construction material. A slurry of solid particles is injected into the fibrous trap when it is still in the gaseous atmosphere of the bell and the trap charged with said particles is then deposited on the construction site (1). The ejector (11) can be part of a device (12) for breaking up textile cable (17) and is connected with a floating platform (3).
