Fully-automatic water-collecting irrigation slope protection device adapted to arid area and construction method thereof

Abstract

The invention discloses a fully-automatic water-collecting irrigation slope protection device adapted to an arid area and a construction method thereof. The fully-automatic water-collecting irrigationslope protection device adapted to the arid area comprises a water-collecting irrigation device, a waterproof geotextile, a diversion layer and a vegetation planting layer. The water-collecting irrigation device is composed of a prefabricated water storage tank, a prefabricated pile and a moisture sensor. Water inlets and water outlets are formed in a body of the prefabricated water storage tankand both the water inlets and the water outlets are provided with filters. The moisture sensor is arranged on the vegetation planting layer. Electronic control valves are installed at the water outlets. The prefabricated pile is located below the prefabricated water storage tank. The prefabricated pile and the prefabricated water storage tank are fixedly connected by welding or bolts. The waterproof geotextile is laid on a slope. The diversion layer is arranged above the waterproof geotextile, and the vegetation planting layer is laid above the diversion layer. The integrated construction of vegetation planting and later irrigation system is realized, and based on an unique irrigation method and slope structure design, water evaporation and deep layer infiltration are reduced, and rainwater utilization rate is improved.

Description

technical field [0001] The invention relates to the field of slope protection, in particular to a fully automatic water-collecting irrigation slope protection device and a construction method suitable for arid areas. Background technique [0002] In order to achieve soil and water conservation and aesthetics of the slope, plants need to be planted on the road slope. Plants cannot grow without water, but water resources are scarce in arid regions. In order to ensure the normal growth of plants, the prior art has proposed a variety of water resource collection and irrigation methods, including slope interception method (CN 108755654 A), hillside nursery stock drip irrigation system (CN 104094720A), water-saving irrigation system (CN 206274913 U) . Existing irrigation technologies are used to irrigate from the surface. In arid and less rainy areas, surface irrigation will lead to evaporation of irrigation water, resulting in poor irrigation effects; Infiltration will no long...

Problems solved by technology

Existing irrigation technologies are used to irrigate from the surface. In arid and less rainy areas, surface irrigation will lead to evaporation of irrigation water, resulting in poor irrigation effects; Infiltration will no longer be absorbed and utilized by vegetation, resulting in a waste of water resources; in addition, the existing slope surface interception and irrigation technology needs to lay many pipes for slope irrigation, which is difficult to construct and expensive to construct; The surface vegetation is mostly planted in the later stage, but the existing technology fails to organically combine the vegetation planting with the later irrigation system, and the water collection irrigation and vegetation planting are constructed separately, resulting in a large amount of engineering and high cost
