Method for manufacturing gabion net bag with upper opening

The invention relates to the technical field of gabion net bag manufacturing, and discloses an upper opening type gabion net bag manufacturing method which comprises the following steps: S1, preparing corresponding materials; s2, making the material into a steel wire; s3, weaving the prepared steel wires into a net; s4, carrying out edge sealing operation on the woven net; and S5, the net subjected to edge sealing is conveyed to a warehouse to be stored, corresponding materials comprise alloy materials, the content of C in the alloy materials is 0.08-0.15, the content of Si in the alloy materials is 0.17-0.37, the content of Mn in the alloy materials is 0.40-0.70, the outer surfaces of the steel wires are coated with metal anti-corrosion layers, the corrosion resistance of the steel wires is effectively improved, and after the steel wires are made into the gabion net bag, the service life of the gabion net bag is effectively prolonged. When the woven net is subjected to edge sealing operation, only the two op
