Characteristics of galvanized gabion net slope protection construction.

①The construction schedule is tight, the project volume is large, and the flood control pressure is high. In addition to backhoe coordination, manual assembly, manual loading, and manual placement are required, which is highly labor-intensive.

② The protection project requires smooth and beautiful surface, full stone filling, and porosity to meet the specification requirements.

③ The construction area is large, the front is long, and the material preparation is difficult

Technical requirements of gabion net .

① galvanized steel wire gabion gabion specifications are M6×2×0.3 and M6×2×0.23, that is, each unit product is made of anti-corrosion low-carbon steel wire with a length of 6m, a width of 2m, and a height of 0.3m or 0.23m. The product is divided into independent units by partitions every 1m inside, and the length, width, and height tolerances are ±5%.

② The galvanized steel wire gabion is produced in one go. The partitions are double partitions. In addition to the cover plate, the side plates, end plates, partitions and bottom plates are inseparable.

③ The length and width of the galvanized steel wire gabion are allowed a tolerance of ±3%, and the height is allowed a tolerance of ±2.5m.

④The grid specification is 6cm×8cm, and the allowable tolerance is -4%/+16%; the diameter of the grid wire is not less than 2mm, the diameter of the edge wire is not less than 2.4mm, and the diameter of the twisted edge wire is not less than 2.2m.

⑤ It is necessary to use a professional flanging machine to wrap the mesh steel wire around the edge steel wire for ≥ 2.5 turns. Manual twisting is not allowed.

⑥ Used to manufacture galvanized steel wire gabions and steel wires for edge twisting. The tensile strength should be greater than 350N/mm2, and the elongation should not be less than 9%. The minimum length of the steel wire sample used for testing is 25cm. The diameter of the mesh steel wire is allowed to have a tolerance of ±0.05mm, and the diameter of the edge steel wire and the twisted edge steel wire is allowed to have a tolerance of ±0.06mm. The steel wire should be tested before the product is made (to eliminate the influence of mechanical forces).

⑦ Steel wire quality standards: The service life of the steel wire used in galvanized steel wire gabions shall not be less than 4a, that is, the anti-corrosion coating will not peel or crack within 4a.
