FIELD: construction. ^ SUBSTANCE: invention pertains to construction and in particular to protection of slopes of structures. The double twist spiral structure, suitable for the wire mesh block, contains n-th upper steel wire (An) and n-th lower steel wire (Bn), which are twined with each other and turned in the same direction so as to form a front spiral twisted structure, k-th transverse steel wire (Ck), which is transversely put between the n-th steel upper wire (An) and the n-th lower steel wire (Bn) of the front spiral twisted structure and the n-th upper steel wire (An) and the n-th lower steel wire (Bn), which are turned in the direction opposite one direction after passing through the k-th transverse steel wire (Ck), serving as a central line, so as to form a rear spiral twisted structure, where k is the ratio of the relative position between transverse steel wires and is a positive whole number including 0, and n is the ratio of the relative position between the upper and lower steel wires and is a positive whole number including 0. ^ EFFECT: increased durability of the structure and quality of strengthening slopes. ^ 6 cl, 4 dwg |
