Further set：The position of the drainage channel is less than the position of blind pipe, and blind pipe is provided with some drainpipe phases
Intercommunicated, blind pipe is communicated in drainage channel by drainpipe.
By using above-mentioned technical proposal, the water in blind pipe can be entered in drainage channel by drainpipe, due to draining
The position of raceway groove is less than the position of blind pipe, therefore ponding can be circulated in drainage channel under gravity.
Further set：The drainage channel is coated with the impervious barrier made of anti-filter geotextiles.
By using above-mentioned technical proposal, because drainage channel is located in saline and alkaline stratum, accumulated when being not present in drainage channel
During water, the moisture in saline and alkaline stratum can enter in drainage channel with silt, cause the blocking of osmos tube, the setting of impervious barrier can
Will isolate between silt and osmos tube, the blocking of osmos tube is avoided.
Further set：The waterproof layer is made up of waterproof geotextiles, plants and gravel filtering is provided between layer and waterproof layer
Layer.
By using above-mentioned technical proposal, gravel filter layer is typically formed by some gravel layings of different sizes, is being planted
Plant sets gravel filter layer tentatively to be filtered rainwater between layer and waterproof layer, prevents rainwater from carrying excessive silt and entering
Enter in aqueduct and blind pipe, cause the blocking of aqueduct.
Further set：Plantation the distance between the layer top surface and waterproof layer are more than 0.4m.
By using above-mentioned technical proposal, during due to plant growth, its root system needs the soil horizon of certain depth, will plant
Layer top surface and waterproof layer the distance between control in more than 0.4m.
Preferably, the blind pipe is communicated in municipal Storm Sewer Network or river course.
By using above-mentioned technical proposal, blind pipe is communicated to the speed that can increase draining in municipal Storm Sewer Network or river course
Degree, prevents ponding from being accumulated in blind pipe excessively.
In summary, the utility model has the advantages that：
Rainwater can trickle to trough along waterproof layer surface during precipitation, and enter from aqueduct in blind pipe and arranged
Put, waterproof layer can separate on saline and alkaline stratum with plantation, can avoid exchanging for water being present between plantation layer and saline and alkaline stratum, prevent
Only saline-alkali water enters in plantation layer the growth for influenceing plant.
