As the road in tourist areas, the higher the roadbed comprehensive improvement of environmental requirements, especially after the end of the required soil conservation and environmental restoration projects. According to local conditions, the proposed gabions retaining wall structure to maintain the embankment, its applicability as follows:
1, in the brook embankment sections, gabion retaining wall is a permeable, breathable structure, can effectively solve the problem of pore water pressure behind the wall, and another between the gabions steps to build soil conducive to ecological restoration.
2, gabions retaining wall layout flexibility, allowing the original preserved everywhere gravel messy neat, clean, and in coordination with the natural landscape.
3, the local slope of gravel mostly quartz sandstone, hard and difficult to weathering, block diameter is generally 10 ~ 50cm, artificial filling gabion is the best material.
4, the local ground conditions change complex, large-scale machinery should not be used during construction. Gabion construction technique is simple, does not require a lot of skilled workers; applicability and without foundation, and then set the other drainage facilities, to meet the requirements.
