Loess slope vegetation planting guarantee PVC board structure system and construction method thereof

Abstract

The invention discloses a loess slope vegetation planting guarantee PVC board structure system. The loess slope vegetation planting guarantee PVC board structure system comprises vegetation planting guarantee PVC board structures vertically driven into a step structure face and a slope surface structure face of a loess slope, multiple soil fixation grids embedded into the vegetation planting guarantee PVC board structures, and vegetation communities formed by vegetation planted in the soil fixation grids. Each vegetation planting guarantee PVC board structure comprises multiple cross-shaped connecting components, multiple middle connecting components and multiple anchor rod mechanisms. The soil fixation grids are rectangular masonry grids formed by connecting left half masonry grids and right half masonry grids which are integrally formed in a butt joint mode. The vegetation communities comprise the step vegetation communities and the slope surface vegetation communities. The invention further discloses a construction method of the loess region slope vegetation planting guarantee PVC board structure system. The loess region slope vegetation planting guarantee PVC board structure system and the construction method are convenient to implement and low in cost, and the method is simple in step, low in engineering manufacturing cost, environmentally friendly, high in practicality and good in application prospect.

Description

technical field [0001] The invention belongs to the technical field of slope protection and ecological restoration, and in particular relates to a PVC plate structure system for planting protection of loess slope vegetation and a construction method thereof. Background technique [0002] With the development of highways, railways and water conservancy projects in China, a large number of slopes have appeared, resulting in the destruction of the original vegetation cover, resulting in the emergence of secondary bare land and serious water and soil erosion, which has aggravated the ecological system. of degradation. Therefore, slope protection and ecological restoration are particularly important. [0003] At present, engineering measures are often used to protect slopes, such as slope drainage measures, mortar rubble, shotcrete, soil nails, anchor rods, retaining walls, anti-slide piles, etc. Although engineering measures can play a role in slope protection, the engineering...

AI Technical Summary

Problems solved by technology

Although the current vegetation planting protection technology can also play a protective role to a certain extent, the effect is not obvious, especially after years of rain erosion, the turf in many places needs to be replanted, and even the soil needs to be replanted in serious places. Filling, resulting in the second phase of maintenance and maintenance, greatly increasing the engineering cost of slope protection

In addition, the vegetation protection in the prior art will reduce the stability of the slope due to the strength damage of the slope reinforcement material in the later stage, and there is no reinforcement measure in the later stage
