At present most people will choose the ecological grid structure for the construction of channel canals and riverbed channels due to the stability of slopes and riverbeds. It can provide effective permanent protection to the river bank or river bed, and it can also control the flow of water. In addition, this type of gabion mesh type ecological structure is also commonly used in slope support, foundation pit support, mountain rock surface net spraying, slope vegetation (greening), railway highway isolation and protection barriers, and and it can also be made for river Anti-scouring protection of dams, sea dams and cages for reservoirs and river closure.
Before foconstruction, it needs to make some preparations works. Foundation pit excavation will be prepared before the construction of the river gabion mesh box. But it needs to conduct a in-depth researchin-depth research for the contract or design documents, and the relevant data, information and geometric dimensions in the construction drawings should be inspected. At the same time, The construction unit should appoint a special person to be responsible for the measurement and provide required measurement data it in time.
Another things, as the gabions systerm is outdoor construction.The meteorological, hydrological and other conditions need to be considered, and a reasonable construction plan should be formulated to ensure that construction machinery, construction tools, equipment and material models, specifications, and technical performance should be reasonably arranged and deployed according to the construction progress and intensity of the project.
As we know, the different materials of gabion wire mesh box have different advantages. They should be selected according to the specific application. The semi-finished gabion cages are processed by the manufacturer to ensure stability and tensile properties. The gabion mesh wire diameter is 2mm-4mm normally.The mesh is uniform and not easily deformed. The deviation of the mesh aperture should be less than 5% of design aperture.
