Abstract A method is disclosed for protecting slopes and crests of rivers, channels, and the like by mooring flexible and permeable tubular casings filled with fresh concrete. Those tubular casings may be made of synthetic fibers, burlap, canvas, etc., and are simultaneously filled with fresh concrete while being placed at the foot of surfaces which must be protected. The tubular casing is lowered by gravity to its position by means of a series of ropes tied to the tubular casing at one of their ends with the other end of the ropes being secured to an element placed at the surface of the water. The ropes provide guides for the mooring of other casings similar to the above-mentioned one with the rolls, loops or rings or any other element being used for aligning purposes through which ropes of the first casing may pass so that the following casing necessarily are placed one over the other until the rolls appear at the surface of the water.
A method for the protection of slopes and crests of rivers, channels, and the like by guided mooring of flexible and permeable tubular casings of great length, filled with fresh concrete, said method comprising the steps of filling a first tubular casing with fresh concrete, mooring it by gravity to the desired position, simultaneously as it is being filled, by means of a series of ropes attached thereto leaving the ends of said ropes free subject to a floating element on the surface of the water, using said ropes as guides for other casings similar to said first casing which are also moored by gravity while simultaneously being filled with fresh concrete, holding subsequently filled tubular casings to the first, the basis for alignment of said subsequently placed casings being ropes held by said first casing and said floating element on the surface of the water, whereby each of said tubular casings may be placed in the desired position.
