Slope Protection Gabion Net Stabilization
Gabion net is a steel woven mesh used to protect railways and highway surfaces from rock and debris falls. The Heavily Zinc coated or PVC + Heavily zinc coated double twisted steel wire netting has hexagonal openings and can withstand the force of falling rocks without unraveling.
Unlike thrown rock or Slope protection gabion net berms, gabions are easy to install and don’t require any special equipment. They are also less expensive than other slope stabilization methods.
Stabilization
Stabilization is one of the most important parts of a slope protection gabion net. It prevents landslides by controlling the movement of soils. Additionally, it protects a slope from water damage and provides stability for plants growing in the area. It is a good substitute for concrete barriers.
The structure is characterized by the use of metal wires with different thicknesses and materials. Generally, the wires are galvanized or PVC-coated. The coating protects the steel from corrosion. It also adds a layer of waterproofing to the net. In addition, the coating is easy to clean and has a wide range of colors.
Compared with welded steel baskets, galvanized gabions are easier to install. Staff can easily transport the complete stone cage net product to the construction site and assemble it into a stone cage structure according to the actual situation at the installation site. This can save a lot of time and labor.
In addition, galvanized gabions are easy to install and require fewer resources than traditional shotcrete. Besides, they are environmentally friendly and can be shaped as needed. They are particularly suitable for river ecological slope protection projects. This is because the structure has excellent permeability and can withstand a certain degree of deformation. It can be used to stabilize steep slopes, embankments, retaining walls, and riverbanks.
Erosion Control
When a slope is prone to landslides, it needs to be stabilized to prevent it from collapsing. Gabions are an effective solution to stabilize slopes and are constructed by filling them with stones. The stones function as a barrier to limit the movement of soil upper and lower the slope, and also serve as velocity dissipaters. This is especially helpful in areas with heavy rainfall.
Gabion structures can be constructed with different materials to suit the environment and the purpose of use, such as welded gabion nets. These structures have a flexible structure, and can withstand large deformations without damage. The welded mesh of these structures can be flexibly adjusted to accommodate changes in the slope environment, and can help maintain the stability of the slopes.
These structures are also used to block rivers and prevent erosion of river banks. They are especially effective during natural disasters like floods, which can cause massive destruction. The welded mesh of the gabion cages can be adapted to the shape of the river bank, and can ensure the water flow is maintained in normal conditions. This will help to avoid damage Slope protection gabion net to the bank and its surrounding ecology. Gabions are a good choice for erosion control because they can be designed to fit in with the surrounding ecosystem, and are easy to construct.
Retaining Walls
Gabion stone walls are often used to stabilize steep slopes, such as those near highways or cliffs. They consist of wire mesh “boxes” filled with rock or other material and stacked in vertical or horizontal “cells.” These structures can flex to ground movement and dissipate energy, and they are particularly effective when the soil behind them is soft. They also provide some resistance to erosive forces, but this can diminish with time as silt and other soil fill the voids.
For flood control applications, gabion walls can be placed on river banks to reduce water flow velocity. They can also be used in ponds or reservoirs to prevent sediment and sand migration downstream. They can also be incorporated into the foundation of bridge abutments.
A variety of stone materials can be used in gabion structures, including gneiss and basalt. Other common stones include granite, sandstone, and marble. The gradation of the rocks is important, as it influences the ability of the structure to resist erosion and other damage. Rocks with a large rounded shape are better than those that are sharp and pointy, as they tend to roll less easily. In addition to selecting the right stone for each application, the contractor must select a suitable filler material, such as geotextile or geogrid. Hanes Geo, a New York-based engineering company that specializes in slope protection structures, has built gabion stone wall systems on sites in New York and Connecticut. The first phase of a project involved setting concrete pads on the slope and installing a geotextile. Then the crew positioned and filled the gabion cages, backfilled and compacted, and placed additional geofabric over both the gabions and the backfill.
Drainage
Gabions are often used for slope protection and river guidance projects. They protect the slope and help to moderate landslides by controlling water flow. They also avert damage caused by floods and mudflows, as well as reduce erosion of surrounding soil.
Because of their durability and cost effectiveness, these structures are becoming more popular than traditional concrete barriers. However, to get the best results, they must be designed and constructed by a professional engineer. This includes consideration of slope width, slope gradient, internal angle of friction, backfill and site constraints. It’s also important to consider the drainage system, as these structures will be exposed to large amounts of fluid pressure.
In this project, Stoic anchored the gabions to a rebar-reinforced concrete pad with 6,000 psi grout. They then built a stepped series of gabions along the stream bank, and placed geofabric over both the pads and the backfill. Finally, they topped the structure with a geosynthetic liner to protect the gabions from bedload movement.
Gabion rock cages are a series of metal mesh rectangular containers filled with stone. They’re typically made of galvanized steel wire, but can be built from copper, stainless steel or PVC-coated materials. These gabions are strong and durable, but their longevity depends on how they’re treated and maintained. To prolong their lifespan, they should be regularly coated with anti-rust and corrosion products to prevent moisture, rust and other damage.
