Description
Technical Field
The utility model relates to a garden engineering, in particular to greenery patches lawn retaining water conservation structure.
Background
At the present stage, along with the deep expansion of concepts such as ecological cities, rainwater gardens and the like, the greening area in cities is also continuously increased, and the problems of reasonable application of urban water resources and secondary utilization of water resources such as natural rainwater, reclaimed water and the like caused by the continuous increase of the greening area in cities are urgently solved.
It is well known that large areas of lawn greenbelts in cities still require a large amount of manual watering to meet the basic needs of daily maintenance. According to the research on the relation between the 18-year green lawn water demand and the 18-year average rainfall in Shanghai, the annual average rainfall is basically equal to the annual lawn water demand, but due to reasons of insufficient seasonal alternative water resource utilization and the like, the concept of collecting and storing excessive natural rainwater in rainy seasons with sufficient rainfall and concentration and then utilizing the excessive natural rainwater in arid water-deficient seasons is not realized, so that the water in the rainy seasons is wasted, the water resources are wasted due to the artificial watering in the arid seasons, and the labor cost for watering is not small. In order to meet the water demand requirement in the drought season, the natural rainfall is reasonably stored and reasonably distributed in time to achieve dynamic balance, and the requirement of the annual water demand of the lawn can be basically met. The main problem is that natural precipitation is not uniform and controllable, and compared with the method that a large amount of precipitation on the lawn and surrounding public areas such as sidewalks is stored and reused in rainy season.
Based on the basic principle of scientific management that excessive rainwater in rainy seasons can seep downwards under normal conditions, a lawn root system only obtains required water in a depth of 8-12cm, most of the part is natural soil, the water storage capacity of the part of soil layer limited by the soil quality of Shanghai is extremely limited, more parts can be lost to the deep layer of the soil to cause waste of water resources, and the loss and the waste of the part of water are aggravated by regular irrigation under the condition of insufficient water retention capacity of the soil in dry seasons, the part can be refined in the aspect of watering, water shortage can be watered again, and watering is not performed more and not in disorder along with the provision of refined gardens.

When the water evaporation of the lawn is accelerated in sunny days, the water content of the soil is gradually reduced from the surface layer to the bottom layer, and the water storage nano plant blanket supplements the water to the vicinity of root systems of the bottom layer under the capillary action to meet the requirement of the lawn on the water content. And (4) trimming the earthwork model into a natural gradient according to the early-stage earthwork model, enabling rainwater to flow to reserved water collecting pipes around and finally collect into the lower water storage equipment, and settling and purifying for secondary use.
The humidity sensor in the water storage nanometer blanket and the control valve on the water inlet pipeline are electrically connected with the controller, when the humidity is lower than 20%, the valve is opened to water, when the humidity reaches 95%, the water stops watering, and the whole system can work normally.
The utility model has the advantages that:
the utility model discloses an it starts to alleviate "sponge" thinking of urban drainage pressure, introduces retaining nanometer plant blanket design thinking to increase the original retaining in lawn and collect the ability of rainwater to a certain extent with the effect of two-layer retaining nanometer plant blanket simulation sponge, the reassembling is the most fiery rainwater collection system further brings street side road urban drainage into wherein has realized the self-sufficient assumption of green low energy consumption of multisource and with the make full use of water resource.
When the water in the water storage nano plant blanket and the water in the water collection tank below the lawn is used, no extra watering is needed, the reserved water collection pipeline can be close to one side of the lawn, namely the sidewalk, and the reserved slope ensures that a part of rainwater in the sidewalk can be collected and reused; and the water storage nano plant blanket at the lower part of the lawn increases the integral water storage capacity of the lawn and relieves the pressure of heavy rain weather on the urban sewer pipe network. When the water in the nano water storage blanket below the lawn is used up, the water can be directly supplemented into the water collection tank, so that the time and the labor are saved, and the water saving effect of the lawn and the utilization rate of peripheral water resources are improved to the maximum extent.
The utility model deeply buries the nanometer plant water storage blanket under the surface of the lawn, greatly improves the whole water utilization rate of the plant root system by utilizing the humidity sensors with different depths and the water storage characteristic of the water storage nanometer plant blanket, and controls watering according to the humidity of the humidity sensor of the root system by combining remote irrigation; and a backflow water collecting pipe is laid at the bottom layer and collected in the lower water tank to form a circulating, purifying and recycling irrigation system. This water tank is connected with rainwater collection system again and guarantees nature precipitation utilization ratio maximize.
Adopt utility model self-loopa water conservation lawn irrigation system, overcome the tradition and spray and cause a large amount of water waste to and the unable reutilization's of rainy season excess water resource shortcoming. And the water resource management and control cost in the maintenance process is reduced to the maximum extent while the water resource is saved.
