Environment-friendly lawn structure for sponge urban greening decoration

Abstract

The invention provides an environment-friendly lawn structure for sponge urban greening decoration. The environment-friendly lawn structure comprises a lawn planting shell, stirring rod structures anda second annular protruding ring structure. A body of the lawn planting shell is in a rectangular block shape. The top sides of the left end face and the right end face of the lawn planting shell areeach provided with a rectangular protruding block structure. The left side and the right side of the bottom end of the inner end of a lawn planting groove structure are each longitudinally provided with a plurality of round through hole structures in rectangular arrays. The round through hole structures are communicated with a water storage cavity structure. The bottom end of a rotating shaft islocated in the water storage cavity structure, two flowing water mechanisms are arranged at the bottom end of the rotating shaft, each flowing water mechanism is composed of the two corresponding stirring rod structures in annular arrays, and therefore when wind blows in ordinary times, the wind can blow a canvas to move so as to drive the rotating shaft to rotate around an axial hole structure, the flowing water mechanisms at the bottom end of the rotating shaft stir natural water resources stored in the water storage cavity structure to move, and the dead water phenomenon is avoided.

Description

technical field [0001] The invention belongs to the technical field of sponge city greening, and more specifically relates to an environment-friendly lawn structure for sponge city greening decoration. Background technique [0002] Sponge city is a new generation of urban stormwater management concept, which can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use when needed. [0003] The bottom of the lawn used for greening decoration in the sponge city is generally equipped with a reservoir to store natural water resources under rainy conditions, so as to provide the water resources needed for the growth of green plants planted on the lawn, but the natural water stored Resources have no liquidity, and after long-term storage, stagnant water is easy to form, and under heavy rain conditions, ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides an environmentally friendly lawn structure for greening and decorating sponge cities to solve the problem that the natural water resources stored in the reservoir at the bottom of the lawn have no fluidity, and after long-term storage, it is easy to form stagnant water. Under the condition of heavy rain, the water level of the natural water resources stored in the reservoir keeps rising, which cannot be effectively discharged, and the problem of overflow is prone to occur
