The gabion (the gabion) being the spiral multi- twist structure which especially is suited for the gabion

摘要

Topic: This invention left and right and the top and bottom continuing the wire cylinder item, and the said wire cylinder item which are formed by the spiral double twist structure for the wire cylinder item bidirectionally, mutually regards the wire cylinder net which repeatedly it makes connect. Spiral double twist structure of the wire cylinder item of this invention the wire of the longitudinal direction 2, on the front and back which makes pass on the wire of the intersection direction 1 it becomes the centerline, features that it turns to opposite direction helically.Solution method: With this invention, as description above the wire cylinder net which was formed the wire cylinder item, and the plural wire cylinder items which were formed by connecting the plural spiral double twist structures for the wire cylinder item which was constructed mutually by repeatedly connecting to left and right direction and top and bottom direction mutually continually is offered. Therefore, it depends on this invention and completely be able to automate former wire cylinder net production method, 2 - 3 time production efficiency than former production method it can improve with that.
