Abstract

The utility model provides an invisible water storage structure in greenery patches: comprises a water receiving port, planting soil, a permeation tube, a water seepage layer and a reservoir; the water storage tank is a circular pit which is leveled on the ground and dug downwards after being tamped, the inner surface of the circular pit is tamped, and broken stones are filled in the circular pit; the water seepage layer is formed by paving broken stones on the ground and the surface of the water storage layer after leveling and tamping the ground; the permeation pipe is formed by paving PVC drain pipes in a row in one direction in a water permeation layer, and the PVC drain pipes are connected with a community road drain pipe network; the planting soil is formed by paving soil on the surface of the permeable geotextile; the green land invisible water storage structure can drain rainwater in a green area into or permeate the ground for storage, and drain the rainwater into a road drainage pipe network after enough rainwater is stored, so that the green area is prevented from being overflowed by the rainwater.

Description

Invisible water storage structure for green land

Technical Field

The utility model relates to a district greenery patches rainwater field of handling especially relates to an invisible retaining structure of greenery patches.

Background

In urban residential districts in China, public greening areas are generally constructed, and when the public greening areas are in heavy rainy days, some greening districts without overflow ports are low in water seepage and drainage treatment capacity of the greening areas, so that water overflows from roads around the greening areas to influence road traffic of the districts.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to prior art's defect and not enough, a stealthy retaining structure in greenery patches is provided, can arrange into the rainwater in the afforestation area or permeate the underground storage in this stealthy retaining structure in greenery patches, and after storing enough rainwater underground, will discharge away the rainwater through road drainage pipe network, prevent that district afforestation area from taking place the condition of water overflow afforestation area road around the district, and when the weather is dry, the rainwater is through the moist soil of infiltration's effect, reduce the water consumption of watering afforestation area summer.

In order to achieve the above object, the utility model adopts the following technical scheme: a green land invisible water storage structure comprises: comprises a water receiving port, planting soil, a permeation tube, a water seepage layer and a reservoir; the water storage tank is a circular pit which is dug downwards after being leveled and tamped on the ground, the inner surface of the circular pit is tamped, the broken stones are filled in the circular pit, and the surface of the filled broken stones is leveled horizontally, so that the underground water storage tank has strong water storage capacity; the permeable layer is formed by leveling and tamping the ground, paving broken stones on the ground and the surface of the water storage layer, leveling the surfaces of the paved broken stones horizontally, and paving a layer of permeable geotextile on the surface of the broken stones, so that soil is blocked on the permeable geotextile, and water penetrates through the permeable geotextile and is stored in the reservoir; the penetration pipe is formed by paving PVC drain pipes in a row in one direction in a water penetration layer, and the PVC drain pipes are connected with a community road drainage pipe network to drain redundant rainwater; the planting soil is prepared by paving soil on the surface of the permeable geotextile, regularly leveling the paved soil, and planting ornamental plants on the surface of the soil; receive the mouth of a river for the PVC drain pipe of perpendicular setting, the periphery of this PVC drain pipe is provided with the rubble, and this PVC drain pipe, rubble and infiltration pipe, water seepage layer are linked together to should receive the top of mouth of a river and set up to the funnel type, and receive the top of mouth of a river PVC drain pipe and be provided with the filter screen, the rainwater that will plant the soil surface overflow drains away.

Preferably, the diameter of the permeation tube is 80mm-120mm, and one permeation tube is paved at intervals of 1800mm-2000 mm.

Preferably, the penetration pipe and the PVC drain pipe adopted by the penetration pipe are provided with perforations on the surface, and the opening rate is not less than 15%.

Preferably, the aperture of the filter screen arranged on the water containing port is 1mm-2 mm.

Preferably, the thickness of the water seepage layer is 200mm-280 mm.

The utility model has the advantages that: this stealthy retaining structure in greenery patches can be discharged into the rainwater in the afforestation district or the infiltration underground storage to after the sufficient rainwater of underground storage, will drain away the rainwater through road drainage pipe network, prevent that district afforestation district from taking place the condition of the road around the water overflow afforestation district, and when the weather is dry, the rainwater is through the moist soil of effect of infiltration, reduces the water consumption of watering afforestation district in summer.

Drawings
