Description

Ecological landscape corridor for intelligent three-dimensional rainwater recycling and workflow thereof

Technical Field

The invention relates to a landscape corridor, in particular to an intelligent three-dimensional rainwater recycling ecological landscape corridor and a workflow thereof.

Background

Many communities, squares, parks and other public areas are provided with galleries, and various flowers and plants can be planted around the galleries and at the tops of the galleries to afforest the surrounding environment. The gallery is typically formed of two rows of sidewall bases and beams at the top of the bases. The frame structure of the gallery is made of reinforced concrete, wood, steel structure and the like. The plants around the gallery need to be regularly maintained, the plant maintenance only depends on natural rainwater irrigation in a small amount, and the rest depends on manual irrigation in a large amount.

At present, most galleries are single in landscape effect and lack space third dimension. If the assembled vegetation boxes are arranged on the two sides and the top of the corridor, various flowers and plants are planted in the vegetation boxes, and the landscape effect of the corridor is greatly improved. In recent years, the concept of 'sponge city' is getting deeper and deeper, and people pay more attention to the collection and reuse of rainwater. The landscape maintenance after the gallery is built needs to consume a great deal of manpower and water resources. If rainwater in the covered and peripheral areas of the corridor landscape can be blocked, and intelligent irrigation is realized by utilizing the blocked rainwater when the corridor landscape needs to be irrigated by means of the PLC control system. The method greatly reduces the subsequent maintenance work and can achieve good economic benefit.
