Greening irrigation system for sponge cities and construction method of greening irrigation system

Abstract

The invention discloses a greening irrigation system for sponge cities. The greening irrigation system comprises a water collecting device, a priming pump device, an aeration device and a greening device, wherein the water collecting device comprises a water collecting pool, a water collector and a purification integrated machine; the priming pump device comprises water feed pumps connected with pump water discharge pipes, the pump water discharge pipes are connected with the aeration device which is connected with a water storage tank, and the water storage tank is connected with water storage tank discharge pipes which are connected with the greening device. The construction method comprises steps as follows: (1), excavating foundation pits; (b), building the water collecting pool, an aeration tank and the water storage tank; (c), pretreating a foundation where ecological greening insert blocks are to be laid; (d), laying the ecological greening insert blocks; (e), planting green plants. According to the system, urban rainwater is collected and treated by the water collecting device, the collected rainwater is purified, put into secondary use and applied to irrigation of the greening device, so that not only is the waterlogging phenomenon of the road surface prevented effectively, but also water resource waste can be reduced through rainwater collection.

Description

technical field [0001] The invention relates to a sponge city green irrigation system and a construction method thereof. Background technique [0002] Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city", an international general term Built for "Low Impact Development Stormwater Systems". Sponge city can absorb, store, infiltrate, and purify water when it rains, and "release" the stored water and use it when needed. Through source reduction, process control, system governance, etc., buildings and communities, roads and squares can be integrated. , parks, green spaces, and water systems have the functions of absorbing, storing, and slowing release of rainwater, effectively controlling rainwater runoff, no water accumulation in light rain, no waterlogging in heavy rain, no bl...

AI Technical Summary

Problems solved by technology

In recent years, sunken green spaces, infiltration ponds, wet ponds, etc. have begun to attract attention and have been rapidly constructed. However, due to the relatively single filler, although the infiltration of surface rainwater has been accelerated to a certain extent, it is difficult to effectively store it, and the rainwater has not been purified. , the rainwater is directly discharged into the river without treatment, which has a certain pollution effect on the river, making the water quality of the river course black and smelly, destroying biodiversity, increasing the cost of urban maintenance, and not using the rainwater. The utilization efficiency is not high, resulting in waste of rainwater resources

In addition, there is no reasonable application of the collected water, such as for irrigation of green land, and an integrated irrigation system is not formed. It is only watered by manual irrigation, which is time-consuming and laborious. Moreover, manual irrigation Subjective and cannot guarantee uniform watering
