Water conservancy projects include flood control, irrigation and water storage projects As in the past, the restoration mode with concrete as raw material is expensive in time and easy to destroy the local ecological environment The gabion net can not only meet the needs of restoration, but also greatly reduce the impact on the ecological environment after restoration The gabion cage has the characteristics of strong stability, which is beneficial to the circulation of natural water and the growth of vegetation
Water conservancy projects include flood control, irrigation and water storage projects As in the past, the restoration mode with concrete as raw material is expensive in time and easy to destroy the local ecological environment The gabion net can not only meet the needs of restoration, but also greatly reduce the impact on the ecological environment after restoration The gabion cage has the characteristics of strong stability, which is beneficial to the circulation of natural water and the growth of vegetation After the flood season, if a layer of soil or natural accumulation of soil is sprinkled on the surface, green plants such as grass can grow, which not only restores the river but also beautifies the environment Galvanized steel wire mesh used in production can be selected to prolong its service life and reduce its maintenance times
This structure can be used for slope support, foundation pit support, mountain rock surface hanging net, shotcrete slope planting (greening), railway and highway isolation protection net can also be made into cage net pad, which can be used for scouring protection of river dam seawall and cage for intercepting reservoir and river
1 Control and guide rivers and floods
It is a serious problem in rivers that water scours the river bank, which destroys the river bank and leads to flooding, resulting in a large number of life and property losses and large-scale soil erosion Therefore, when dealing with this problem, it is necessary to use gabion net, which can protect riverbed and river bank for a long time
2 Canal riverbed
The construction of canal involves the stability of slope and riverbed Therefore, the selection of gabion net is the main method used in many natural river channel reconstruction and artificial river channel excavation in recent hundred years It can effectively protect the riverbank or riverbed, and also has the function of controlling water flow and preventing water loss, especially in environmental protection and water quality maintenance
3 Revetment and Protection
The application of gabion net, river bank protection and toe protection are very successful examples Give full play to the advantages of ecological grid and achieve the ideal effect that other methods can not achieve
