A water storage and moisturizing combined planting tank suitable for roof greening

Abstract

The invention discloses a water-storing moisturizing type combined planting tank suitable for roof greening. The water-storing moisturizing type combined planting tank comprises tank bodies, U-shaped water permeable bricks, a spray pipe, humidity sensors and an irrigation control cabinet, wherein each of the tank bodies comprises a planting tank and a water spilling tank which are in intercommunication; openings are formed in the upper ends of the planting tanks, and openings formed in one sides of the bottoms of the planting tanks communicate with the water spilling tanks; the U-shaped water permeable bricks are made from water permeable foaming concrete, and each of the U-shaped water permeable bricks comprises a U-shaped tank structure and a plurality of water absorption feet arranged at the bottom of the corresponding U-shaped tank structure, and the U-shaped water permeable bricks are arranged in the planting tanks; planting soil is stuffed to the U-shaped tank structures; the spray pipe is fixed to the side wall of the planting tanks through support frames and communicates with a water inlet pipe; and the humidity sensors are inserted into the planting soil, and the humidity sensors and the water inlet pipe are respectively connected with the irrigation control cabinet. The water-storing moisturizing type combined planting tank can monitor soil moisture and control irrigation.

Description

technical field [0001] The invention relates to a water storage and moisturizing type combined planting tank suitable for roof greening, which belongs to the technical field of environmental protection. Background technique [0002] With the deepening of urban construction ecology and landscape concepts, roof greening can increase the area of ​​urban green space, improve the deteriorating human living environment space, open up human green space, build garden cities, improve people's quality of life, and beautify the urban environment. Ecological effects are of great significance. Studies have shown that ungreen roofs are an important cause of urban temperature rise. In recent years, countries around the world have been devoting themselves to the development and promotion of roof greening technology in order to alleviate the urban "heat island" effect, save energy, and improve air quality. [0003] Roof greening not only helps the city's energy saving and environmental prot...

Problems solved by technology

However, there are still many problems in the process of building gardens on the roof, such as limited load-bearing, harsh living conditions for plants, difficulties in soil moisture retention and maintenance, and easy damage to the roof’s water-resistant layer.

Among them, due to the sufficient sunlight on the roof, high temperature and dry air, it is difficult to keep the soil moist and maintain, and some plants that require high soil moisture are difficult to survive.

At the same time, roof greening also puts forward higher requirements for water-proof materials. The damage of the roof water-proof layer due to construction or later aging will seriously affect the normal use of the building, which also makes it difficult to promote the construction of roof gardens.
