Construction technology of gabion net

According to the construction data of gabion net, gabion net shall be used for slope protection at the upper part. Gabion net with width of 0.5m shall be set at the top of the revetment. The slope length of the slope protection shall be excavated (compacted) to form a consistent slope according to the actual terrain. The upstream slope ratio of gabion net slope protection is 1:2. The thickness of gabion net slope protection is 0.3~0.4m. A layer of geotextile inverted filter shall be set between the gabion net and the foundation. The surface of the gabion net shall be covered with soil and grass, and the lower toe protection shall be riprap toe protection.

Gabion gabion net is a six hinged and hexagonal mesh structure made of 10% aluminum zinc alloy low carbon steel wire with plastic coating and anti-corrosion treatment and woven by mechanical hinge. Construction process of gabion stone dragon net: during slope construction, fill from the slope toe to the slope top, and it is necessary to fill more than two layers of stones in the cage, and it is necessary to place them orderly manually to reduce the porosity as much as possible.

Before binding the cover, the whole structure shall be checked, and the local areas with twists and turns, deformation and uneven appearance that do not meet the construction requirements shall be checked to see whether the stones are fully filled and dense, and whether the upper surface is flat. If the clapboard is zigzag, it can be corrected by moving the bulged side to another square, and then straightening the clapboard, or straightening it with a steel rod. After passing the inspection, use 3M and 6m long binding steel wires to connect the cover plate with the edge of the side plate, end plate and diaphragm.

The binding shall be in strict accordance with the drawing planning and standard requirements. The open space shall be controlled at 10~15cm, and the single circle double circle single circle shall be replaced. The marginal steel wire on the end plate or side plate of the adjacent box shall be tightly bound with the marginal steel wire of the cover plate. For diaphragms whose top and stranding are not in place, steel rods shall be used to lift them up, and then steel wires shall be bound. After the cover plate is bound, all binding edges shall be in a straight line, and several steel wires at the binding point shall be close to each other. If the binding is not close, steel rods shall be used to lift them up for calibration, so as to ensure that the appearance of the same layer is necessary on the same horizontal plane, so as to be horizontal, vertical and beautiful.
