What should we pay attention to in the construction quality of gabion mesh?

1 Excavation of foundation pit. The construction unit must inspect the relevant data, information and geometric dimensions in the construction drawings according to the design documents; the construction unit should designate a person to be responsible for the measurement work and provide the required measurement data in a timely manner. 2 Laying out and positioning. Confirm the position of the cage according to the coordinates of the positioning points in the plan, and pull the wire at the control point to confirm the plane position of the cage. During construction, the borrowed or set construction control signs and elevation points must be strictly protected, and regularly inspected and corrected. 3 Binding of empty cages. The spacing mesh of the cage should intersect with the mesh body at 90° before binding can be carried out. Each combined wire binding must be double-stranded and twisted, and the binding spacing must meet the design requirements. All cage corners, adjacent side wires, and the intersection of side wires and mesh surfaces must be tied with a double strand every 625px. 4 Placement of empty cages. Connect and tie other cage units. Place the cages in place according to the layout line and design requirements, and tie each set of cages with the adjacent cages above, below, left and right with double strands, and tie them at the edge wires and the edge wires and the mesh. Tie the mesh joint surface of the adjacent unit cages at 2 places per square meter. 5 Thoroughly check whether the empty cage is consistent with the layout control line and whether the cage elevation meets the design requirements. Only after there is no problem can the next step be carried out. 6 Tie wooden sticks (steel pipes, bamboo poles, or templates) on the exposed surface to ensure the flatness of the exposed surface, and remove them after the capping is completed. 7 Fill with stones. The particle size of the stone filling in the cage must meet the design requirements; the exposed layer of stone filling must be manually stacked, and the stones need to be stacked flat to ensure flatness to ensure the appearance; the exposed side of the cage must be set with horizontal fixing wires, which are set after each layer of the cage filling stone reaches 625px and is flattened. The horizontal fixing wire is in the shape of an "eight"; the material must be added to each box grid of the same layer in sequence, evenly and layered, and it is strictly forbidden to fill a single grid cage at one time. The 1250px high cage is divided into two layers of material; after each layer of the cage is filled with stone, it is necessary to use fine crushed stone to correct the flatness of the top of the cage before it can be capped. 8 After each layer of the cage is capped, check whether the elevation meets the design requirements before the top layer of the cage can be installed.
