Plant protection method of rainwater retention and storage system for ecological roof greening

Abstract

The plant protection method of the rainwater retention and storage system for ecological roof greening comprises the steps that when it rains in the rainy season, filtered rainwater infiltrates water absorption cores in the center plastic water storage pool and the lower water opening greening pool, and after the water absorption cores are wetted, the filtered rainwater is absorbed through expansion; when the climate is dry and the greening soil layer is relatively dry, the water absorption blanket below the greening soil layer is synchronously dried and shrunk, the water absorption of the water absorption blanket and the filtered rainwater in the water absorption core move upwards and are continuously conducted to the water absorption blanket, and the water absorption blanket continuously absorbs the filtered rainwater in the water absorption core and conveys the filtered rainwater to the dry greening soil layer to be in contact with the dry greening soil layer. The filtered rainwater in the moist water absorption blanket is absorbed, the filtered rainwater gradually permeates upwards through the greening soil layer, the greening soil layer absorbs the filtered rainwater, and moisture is provided for flowers and plants after the greening soil layer is moistened; when the weather is dry, it can be ensured that the greening soil layer and the roots of flowers and plants are wet, it is ensured that the flowers and plants have stable survival conditions, and greening of the ecological roof is ensured.

Description

technical field [0001] The invention relates to ecological roof greening, in particular to a plant protection method for an ecological roof greening rainwater storage system. Background technique [0002] At present, in recent years, my country's urban roof greening construction is in full swing, making the urban environmental conditions close to the original natural ecological background and hydrological signs; more time must rely on artificial replenishment, mainly through artificial direct pouring or setting up spray and drip irrigation systems mostly. However, manual watering is time-consuming and labor-intensive, especially during high-temperature periods. Due to the rapid evaporation of high-temperature water, water needs to be watered one to several times a day. Plants that are not watered in time during holidays or personnel adjustments sometimes die. Water supply is labor-saving than artificial irrigation, but it will increase construction costs and consume energy. ...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the time-consuming and labor-intensive artificial watering of ecological roof greening, especially during high-temperature periods. Due to the rapid volatilization of high-temperature water, water must be watered one to several times a day, and plants that are not watered in time during holidays or personnel adjustments will die Phenomena happen from time to time; if spraying and drip irrigation projects are set up to supply water, it will save more labor than artificial irrigation, but it will increase construction costs and consume energy. There will be many faults in long-term use, and repairs will not be timely, causing plants to die, and the risk of planting is extremely high; during plant growth A large amount of tap water is required, and when there is a large amount of rainfall, the rainwater is discharged through the sewer pipes and cannot be stored, and the problem of urban green roof irrigation is difficult to solve; now, through a reasonable design, a plant protection system for an ecological roof green rainwater storage system is provided Method; the rainwater stagnation system of the present invention is located under the green pools and respectively reserves rainwater storage tanks; the green pools are respectively equipped with plastic inner pools, and the bottom of the plastic inner pools is provided with a bottom tray. When the rainfall is heavy, the rainwater on the roof passes through The rainwater inlet hole enters the storage tank for storage; a water-absorbing blanket and a water-absorbing core are arranged between the plastic inner tank and the rainwater storage tank. The continuous water replenishment of the greening soil layer can ensure that the greening soil layer and the roots of flowers and plants are moist, ensuring that the flowers and plants have stable living conditions, and the flowers and plants will not die during holidays or personnel adjustments, ensuring the greening of the ecological roof
