Lead wire gabion
The lead wire gabion project originated in China as well as papermaking and gunpowder. Before the Qin Dynasty more than 2000 years ago, the working people of China built the world famous Dujiang Weir Project on the Minjiang River in the upper reaches of the Yangtze River. The project used a large number of bamboo woven gabions to block the water for dam construction. This is the earliest lead wire gabion in the world known to date.
In Britain in the 16th century, lead wire gabion nets appeared in the form of wicker baskets filled with dirt, used as artillery shelters for military grounds. In the 17th century, Japan was the first to use a form of lead wire gabion in flood prevention and danger prevention projects. In the early 18th century, Italy began to use bag-shaped lead wire gabions to repair and strengthen river banks.
Modern lead wire stone cages use mesh rectangular boxes woven from galvanized iron wire. The box is filled with stones or natural pebbles for various water retaining projects and anti-scouring buildings.
Weaving method of lead wire gabion:
Lead wire gabion weaving methods include mechanical production and hand weaving.
The speed of hand weaving is slow and the mesh is not uniform, which is not suitable for mass production.
The mechanical production weaving mesh is uniform, fast and efficient, which is 50 times that of artificial weaving, which can be used for large-scale production. The lead wire stone cages produced by our company are double-twisted hexagonal metal mesh woven by advanced machinery at home and abroad. The diameter of the steel wire can reach 2.00mm-4.00mm. In order to improve the structural strength of the cages, each cage is divided into an interval of about 1M to make a spacer. In the process of weaving each lead wire gabion mesh, the diameter of the side wire is greater than the diameter and twist of the strand Double wire thickens one wire size to improve the firmness of the mesh.
