Inflatable barriers for watercourses
Abstract
Abstract This invention relates to inflatable barrier means for retaining water in a watercourse, for example a river, and of the kind comprising at least one inflatable enclosure secured to an element anchored directly or indirectly in such watercourse and constructed in such a fashion as to prevent erosion. In order to enable the barrier means to be easily removed from the watercourse, for example to be used in another location, the invention provides means for anchoring the enclosure in relation to the watercourse bed, and this means incorporates an anchoring strip of supple material such as rubber that is securable to the bed, and this strip has a free extremity or edge provided with one or more means for removably connecting the barrier to said strip. The anchoring strip may be secured to a rigid member arranged to be laid down in the soil of the bed of the watercourse and this rigid member may take the form of a block of masonry. Alternatively, the anchoring strip may be embedded in the soil of the bed of the watercourse by digging out a transverse trench using the removed aggregates to form a temporary dam, laying the anchoring strip in the trench preferably at an angle of 45* to the plane of the bed, and then filling up the trench with the aggregates previously dug out, thus to secure the strip in relation to the soil of the bed.
