A high and steep slope vegetation restoration water control system

Abstract

The invention provides a high-steep slope vegetation recovery water control system, which has a bottom-to-top structure: a water infiltration control layer, which is laid on the surface of the high-steep slope body, and the size of the geocell is 10cm*10cm, and the height is 10cm; The growth matrix is ​​filled in the geocell; the microporous water storage bag and the capillary drainage strip are buried in the plant growth matrix and located in the geocell. The high end of the capillary drainage strip is a free end, and the low end extends into the micropore The water storage bag is welded and fixed with the microporous water storage bag. The high and steep slope vegetation restoration water control system can make full use of natural precipitation and reduce slope runoff. Under the condition of drought and water shortage, the microporous water storage bag can act independently. The plant growth substrate provides water to meet the needs of plant growth. At the same time, it can reduce or even eliminate the use of water-retaining agents, reduce construction costs, reduce manual maintenance procedures, and realize adaptive regulation of vegetation recovery water.

Description

technical field [0001] The invention belongs to the technical field of restoration and management of vegetation on high and steep slopes, and in particular relates to a restoration water control system for vegetation on high and steep slopes. Background technique [0002] Water is an important factor affecting environmental variation, and it is also the main restrictive factor for vegetation restoration and ecological environment construction. Especially for high and steep slope vegetation, due to the special site conditions of the slope, the actual water intake of the slope is significantly smaller than that of the flat land. Coupled with the large slope, it is easy to form surface runoff during rainfall, and the slope is affected by perennial strong winds, which intensifies the water loss of the slope. Therefore, water regulation has become a key constraint factor for vegetation restoration on high and steep slopes. [0003] At present, slope vegetation restoration mainly...

Problems solved by technology

[0004] First, the construction process is relatively cumbersome, and the sprayed base material has a certain weight, and increasing the slope load is not conducive to slope stability;

[0005] The second is that the distribution ratio of the spraying matrix components is relatively complicated, especially the composition of the water-retaining agent has as many as 5 types, which increases the construction cost on the one hand and is easy to operate incorrectly on the other hand and cannot play the role of water retention;
