Afforestation retaining facility with water source adjustment function and construction method thereof

Abstract

The invention relates to a green earth retaining facility capable of regulating water resources and construction method thereof. The earth retaining facility comprises wall body and controller, wherein the outside of the wall is provided with many rows of planters inside which earth layer and water filtering layer are provided successively from top to bottom. Between earth layer and water filtering layer water-permeable geotextile is provided; controller determines whether it rains according to the change of water level through water level change controller. When it does not rain and there remains water in reservoir, the controller starts water pump to pump water in the reservoir to the top of the wall at interval of fixed time and sprays water to the plants in the planters through spray nozzle. Inside wall body water barrier and water permeable layer are provided. Reservoir is connected with storage facilities. By utilizing the new power of solar power to provide power, the green earth retaining facility is energy saving and environmental friendly and has smart design, sufficiently regulating water storage and reazling the regulation of water resources in the city.

Description

technical field [0001] The invention belongs to the technical field of urban drainage and waterlogging prevention and greening landscape, and in particular relates to a greening soil retaining facility with the function of regulating water resources. Background technique [0002] There are many retaining structures in today's cities, the most important ones are retaining walls, which are mostly concrete components and have a cold and hard appearance. After water is discharged from the drain hole on the concrete wall, it is easy to efflorescence along the wall surface, which affects the durability of the structure and affects the appearance; the scattered flow of the concrete drain hole is easy to cause erosion of the backfill soil in front of the retaining wall, which will cause damage over time. Part of the backfill soil in front of the wall is lost, the foundation at the toe of the wall is softened, and the bearing capacity is reduced. [0003] With the expansion of the c...
