Rainwater greening automatic irrigation device and construction method thereof

Abstract

The invention discloses a rainwater greening automatic irrigation device. The rainwater greening automatic irrigation device comprises a purification device, a rainwater collection device and a drainage device, the rainwater collection device is laid on the ground, the rainwater collection device is made of a permeable material, the bottom of the rainwater collection device is connected with a water storage device, the water storage device is connected with one end of the purification device in a communicating mode, the other end of the purification device is connected with the drainage device, and the drainage device drains water for greening irrigation. A method comprises the following steps: a, construction preparation; b, machining of the rainwater collection device and the water storage device; c, mounting of the water storage tank, the purification device and the drainage device; d, mounting of a water permeable brick body; and e, soil landfill. Rainwater is reasonably utilized for irrigation, so that the effect of saving water resources is achieved, meanwhile, the rainwater collection device, the water storage device, the purification device and the drainage device are all arranged underground, and therefore the occupied space of the rainwater greening automatic irrigation device is reduced.

Description

technical field [0001] The invention belongs to the technical field of greening facilities, and in particular relates to a rainwater greening automatic irrigation device and a construction method thereof. Background technique [0002] Water is a natural resource that human beings depend on for survival. With the increase of population and the rapid development of economy, people's demand for water is also increasing year by year, especially in cities with water shortages. Water resources limit the development of local economy to a certain extent. , causing inconvenience to residents' lives. In the greening facilities, the water source wasted due to the water used for plant green land irrigation occupies a large proportion. [0003] The water supply for plants is generally to use water pumps to irrigate. Generally, groundwater and water in the river are used for irrigation, which increases the cost of greening facilities, is not conducive to the protection of water resources...

AI Technical Summary

Problems solved by technology

[0003] The water supply for plants is generally to use water pumps to irrigate. Generally, groundwater and water in the river are used for irrigation, which increases the cost of greening facilities, is not conducive to the protection of water resources, and is not conducive to saving water resources. At the same time, a large amount of rainwater falls to the After the ground, it is collected into a stream and discharged, and soon seeps into the ground, which cannot be used for watering the garden trees. During the construction of the device, due to the need to collect rainwater, the device is buried underground, resulting in the underground soil and moisture affecting the device. Causes corrosion, thereby reducing service life
