FIELD: fencing, for example fences, enclosures, corrals based on spiral members and adapted to be erected around temporary or permanent protected territories.
SUBSTANCE: spiral block includes three spirals having the same diameters and formed of barbed strips. The spirals are directed so that the strips create triangular prism. All coils of adjacent spirals are connected in pairs in connection points uniformly distributed around coil periphery and are collinear with each other along spiral length. Block is provided with transport conveyer including two detachable metal frames. End spiral coils reinforced with wide cores are fixedly secured to the frames. Metal frame sides have locks for container creation and frame fixation. The locks have ears arranged in lower and end parts thereof to secure spiral block to ground and to connect containers with each other.
EFFECT: increased operational capabilities and safety during block mounting and demounting.
