Description
Technical field
The invention belongs to environmental geotechnical field, be specifically related to a kind of for domatic soil body cover layer thin or semiarid zone
Side slope vegetation supply water slope protection device.
Background technology
In side slope protection field, carry out ecological revetment, not only environmental protection in side slope plantation vegetation, and with low cost, utilize
Side slope vegetation ecological revetment mainly uses the deep root anchorage effect of vegetation, shallow root reinforced action, reduces slope body pore water pressure, control
Soil erosion processed, rainfall interception and the impact etc. of reducing erosion Slope Stability.But owing to side slope landform is unfavorable for stopping of rainwater
Long-pending, especially thin at domatic cover layer or the side slope of semiarid zone, although rainy season obtains precipitation recharges and disclosure satisfy that slope vegetation
Growth needs, but in dry season usually because soil moisture deficiency causes vegetation withered, have a strong impact on the bank protection effect of vegetation.
China has a large amount of hand excavation's side slope, the general gradient of these side slopes to lack greatly and often the soil layer thickness of necessity at present
Degree, is unfavorable for the growth of vegetation, and protection effect is poor.Then there is arid and semi-arid region on a large scale in the northwest of China, North China, such as yellow
Soil district, although side slope soil thickness is big, but the dry climate environmental constraints vegetation growth of side slope, become soil erosion tight
The area of weight.The subject matter that current slope ecological bank protection construction exists: artificial vegetation usually needs to irrigate, and maintenance cost is high,
Vegetation easily dries up in dry season, and the holding capacity of Regional Precipitation is weak, and vegetation is low to the interdiction capability of rainwash, control domatic soil
Grain loss effect is little.Therefore, it is badly in need of exploring the ecological revetment new technologies of economical and efficient.
Summary of the invention
The present invention is directed to the irrigation dependency problem that existing ecological revetment exists, it is provided that a kind of for semiarid zone side slope
