TECHNICAL FIELD

[0001] The present application relates to a kind of vegetation bag cofferdam pit transplanting green system and construction method, it is mainly applicable to abandoned gully slope transplanting green construction. BACKGROUND

[0002] At present, the ecological restoration of mine wasteland has been highly valued by countries. Unmanaged mine wasteland is a major hidden danger of environmental pollution, soil erosion and land desertification, and the consequences pose a serious threat to economic development and human survival, so the ecological restoration of mine wasteland is imperative.

[0003] Vegetation protection of rock slope has become the consensus of the engineering community, and vegetation bag protection is one of the effective green technologies. The core is to create a surface that allows plant growth and development and is not easily washed away. In practical engineering, artificial vegetation bag is used to form a substrate layer, and the goal of restoring ecological vegetation is achieved after maintenance. However, how to fix the vegetation bag slope in a steep rock slope is a problem that has not been solved. Due to the characteristics of rock slope, there is no soil cover on the slope surface, and the rock is exposed. The slope is usually steep, and the surface is uneven. Some slopes are even accompanied by reverse slopes or fish-scale pits. When vegetation bag protection is applied to rock slope protection, the vegetation bag is prone to collapse when laid along the slope. Therefore, how to fix the vegetation bag on the rock slope is a major technical difficulty.
