Abstract: A caisson for maritime works, consisting of a base (1) and at least one lateral wall (2) attached to the same and formed by a plurality of voussoirs (3). Within the same a main space (4) is defined, intended to receive granular material as ballast. The voussoirs (3) feature an upper side (5), a lower side (6) and lateral sides (7) and are arranged with the lateral sides (7) of adjacent voussoirs (3) attached to each other, forming horizontal segments (8). Said horizontal segments (8) are attached to other identical horizontal segments (8) to define the lateral wall (2) by means of the union of the lower sides (6) and upper sides (5) of the voussoirs (3) forming the same. The base (1) has a geometric shape which coincides with the geometric shape of the horizontal segments (8). A procedure for the assembly of said caisson for maritime works is also described.

Abstract: A caisson for marine works particularly intended for use in vertical dikes which is formed by a plurality of segments (1) meant for being joined co-laterally therebetween by joining means to form a ground slab, wherein the segments (1) comprise an internal sector (2), lateral sectors (3) and an external sector (4), where said external sector (4) incorporates coupling elements; and by a series of voussoirs (5) meant for being disposed co-laterally therebetween and on the ground slab to form a surface of revolution, having an upper side (6), lateral sides (7) with interlocking means for interlocking the voussoirs (5) therebetween and a lower side (8) meant for being inserted in the segment (1) coupling elements. All of the caisson's elements are manufactured from fibre-reinforced polymer materials.
