A method of constructing a lawn water-saving structure

Abstract

The invention relates to a construction method of a water-saving structure for lawn. According to the method, a radiation spider-web shaped water storage and preservation ditch is dug on the original soil layer of the lawn and a lawn water-saving structure is constructed, a water storage unit is arranged on the lower part of the water storage and preservation ditch, a water absorption and preservation unit is laid on the water storage unit, a lawn original soil layer is laid on the water absorption and preservation unit, a water drain pipe is arranged on at least part of the outer side of the water storage unit, and a breathable layer and a substrate layer are laid in sequence from top to down on the lawn original soil layer. According to the water-saving structure for lawn, the water content utilization rate can be significantly increased, and the water-saving aim for the lawn is achieved; through the combination of lawn irrigation, water draining and water storage, the aim of water draining at large amount of water and water preservation at less amount of water is achieved, the water content in the soil is absorbed by the absorbent stones to be used by the grass roots, and the water storage and preservation ditch is built under the ground to store the water content.

Description

technical field [0001] The invention relates to the field of landscaping, in particular to a method for constructing a lawn water-saving structure, which is especially suitable for the construction of landscaping lawns. Background technique [0002] As the problem of water resources becomes more and more prominent, my country has realized that in order to achieve sustainable and healthy development of garden construction, it is necessary to develop water-saving garden green space. At present, in the urban green space irrigation, the vast majority still adopts rubber tubes to flood the green space with large water. In this method, about 80% of the water is lost due to deep seepage and evaporation. Similarly, more than 90% of the water replenished by rainfall to urban green space is not used by green space and is lost. If about 30% of irrigation water and rainwater are retained through technical treatment, the water consumption for garden green space irrigation can be greatly ...

Problems solved by technology

[0003] The root system of the lawn is relatively shallow, 80% of which are distributed in the soil layer above 40cm, and more than 50% are in the range of 20cm below the surface. It is difficult for it to absorb the soil moisture in the deeper soil layer to ensure its own growth. Irrigate and replenish water, and once the water is lacking, the lawn will not grow well
