In order to strengthen the strength of gabion net cage structure, all the surface net plates are controlled and guided by steel wires with thicker diameters at the side ends of rivers and floods, flood discharge dams, diversion dams, rock collapse protection to prevent soil erosion, bridge protection, soil fixation structure, seashore defense engineering, port engineering and retaining wall road protection
In order to strengthen the strength of the gabion cage structure, all the edges of the face mesh panels are made of thicker diameter steel wires to control and guide rivers and flood flood discharge dams, diversion dam rock fall protection, water and soil erosion prevention, bridge protection, soil consolidation Structures, coastal defense works, port works and road protection with retaining walls.
How to check whether the lead wire gabion net is qualified
Lead wire gabion net is made of anti-corrosion and wear-resistant high-strength low-carbon high-galvanized steel wire or 5%-10% aluminum-zinc alloy coated steel wire, which is mechanically twisted and woven into a multi-twisted, hexagonal mesh mesh. . The length of the twisted part of the pair of wires should not be less than 5cm, so as not to damage the protective coating of the steel wire.
The lead wire gabion net checks whether the geometric dimensions of the bottom protection meet the requirements: the allowable deviation of height: ±10%, the allowable deviation of width and height: ±3%, the allowable deviation of length and height: ±3%, and the flatness height difference ≤3cm.
The wire diameter of the lead wire gabion net: the plus or minus value should be controlled within 0.05mm, this standard needs to be well controlled, the measured wire diameter is between 1.98-2.03mm, within this data value is the qualified lead wire gabion net .
Look at the surface: the mesh should be uniform, the hot-dip galvanized layer should be uniform, so that the anti-corrosion effect can be ensured, and the tensile strength of the lead wire gabion should be 120N, otherwise it will be regarded as unqualified.
The pores between the stones in the lead wire gabion net create conditions for water flow, realize the natural exchange between the water body and the soil, and create a living environment for aquatic organisms and microorganisms, thus enhancing the self-purification ability of the water body, protecting and improving the environment. For water quality, the outcrops at both ends of the lead wire gabion should not exceed 2mm, and the diameter and weft of the lead wire gabion mesh must be strengthened.
