METHOD OF PRODUCING CEMENT SEGMENTS FOR TUNNELS, REINFORCED WITH COMPOSITE MATERIAL

Method of producing cement segments (100) for tunnels, reinforced with composite material, and product thus obtained, consisting of the steps of: (A) preparing the unidirectional composite yarn (8), and transferring it to a nozzle (6);(B) making the primary reinforcement (1), by the sub-steps of: (B.1) arranging fixed pins (5) on a translating board (4) which moves through a moving mechanism; said fixed pins (5) forming a closed polygonal line (9) corresponding to the shape of the primary reinforcement (1); (B.2) pre-tensioning, in which the unidirectional composite yarn (8) is pretensioned around the closed polygonal line (9); (C) making the secondary reinforcement (2), by the sub-steps of:(C.1) arranging a plurality of fixed pins (5) on said board (4); (C.2) pre-tensioning;(D) assembling the primary reinforcement (1) into the housings (2.1) arranged on the secondary reinforcement (2), forming the structural cage (10) of the segment (100); (E) strengthening, in which a seam is made to stably connect the primary reinforcement (1) to the secondary reinforcement (2); (F) casting, in which the concrete is cast forming the cement segment (100) for tunnels.
