Description

Technical Field

[0001] The utility model relates to the technical field of slope ecological restoration, in particular to a water-retaining coiled material used for highway slope ecological restoration. Background Art

[0002] In order to ensure the protection and stability of rock slopes, plain concrete sprayed anchor support is often used on the slope surface. Although sprayed anchor support solves the problem of slope protection, it cannot restore the slope vegetation, which brings about problems such as heat island effect, food chain destruction, and visual pollution, and can no longer meet the requirements of ecological slope protection. To solve these problems, it is necessary to carry out ecological transformation of rock and concrete slopes.

[0003] Rock and concrete slopes usually do not have the soil and nutrient conditions for vegetation to grow, and the slopes are generally large, so rainwater can easily scour the slopes. Therefore, rock and concrete ecological protection has become a research hotspot and construction difficulty in slope construction. Existing slope ecological protection measures mainly include soil spraying and frame vegetation protection. Frame vegetation protection is to use stone masonry or concrete pouring on the slope to form square, arched, herringbone and other shapes of frames, and then fill the frames with soil or earth bags for greening. The disadvantage is that this structure has the characteristics of high construction difficulty and difficult frame forming for steep slopes with a slope of more than 60°. Another problem that is often overlooked is the suitability of the frame and the foundation. When the frame and the rock properties of the slope have a large difference in stiffness, the frame often cracks, breaks or hangs.

[0004] The foreign soil spraying technology is to mix foreign soil, fiber, erosion prevention agent, slow-release fertilizer and seeds in a certain proportion, add them to special equipment and mix them thoroughly, and then spray them onto the slope surface through pumps and compressed air to form the required base thickness, so as to achieve the purpose of greening. The characteristics of this method are strong suitability and relatively simple engineering measures. However, there are also significant disadvantages. When used on rock slopes, due to the thin thickness of the base layer, poor water retention, it is difficult to retain nutrients, and it is difficult to form a self-regulating ecological environment required for the long-term growth of vegetation. Therefore, the maintenance cost is high and it is not easy to manage, especially in areas with insufficient rainfall or in seasons with little rainfall; in addition, when encountering high-intensity rainfall, it is easy to cause erosion and loss of the base layer. Therefore, although this method is currently widely used, it is basically only suitable for soil slopes. Utility Model Content
