Application examples: according to the structure of embodiment 1, hypothallus is prepared with a thickness of 20cm, as embodiment 2, hypothallus thickness
For 30cm, as embodiment 3, outflow process in different designs raininess, the measurement result of 1 structure of embodiment is as schemed
Shown in 6, the measurement result of 2 structure of embodiment is as shown in fig. 7, the measurement result of 3 structure of embodiment is as shown in Figure 8.Pass through comparison
Thickness of soil is performance of three embodiments of 10cm, 20cm and 30cm under five different designs raininess, the results show that
Under each play rainfall, as growth trend is presented in the increase contributing time of soil thickness, but in chance high-intensity rainfall in 50 years one
Lower soil thickness influences contributing time unobvious.In terms of runoff deadline, when generally ending in 20cm soil thickness
Between longest, differ for 5.38 to 9.63 hours, have good retentivity to rainfall, when this numerical value in correlation model to emptying
Between parameter setting have directive significance.In terms of peak value, gradually increased as soil thickness increases peak clipping amount and prolongs peak time,
The peak clipping and to prolong peak effect the most obvious in soil layer 30cm thickness, but 10cm soil layer performance at this time is most from the aspect of total cost performance
It is good.Effect is most obvious under different rainfalls when 30cm soil layer in terms of reservoir storage, and 20cm soil layer has preferably under different rainfalls
Performance, sexual valence is best.So in terms of comprehensively considering soil thickness, comprehensive performance is best when 20cm, cost performance also highest.Analysis
The soil box of the roof structure of each embodiment is found after producing stream situation under different raininess: each soil box is under middle low field time condition of raining
Contributing time carryover effects are obvious, are intended under high-intensity rainfall 4 minutes；The skeleton symbol Green Roof of turf is laid in difference
Runoff deadline under condition of raining, difference was little at two hours or so, and with soil layer construction Green Roof 5 to
It puts up the best performance under chance rainfall in 10 years one；In terms of peak clipping amount, each soil box is put up the best performance under chance rainfall in 10 years one；In terms of prolonging peak time
It is then that effect is the most significant under the chance rainfall in such as 2 years one of ground intensity rainfall, average every increase 10cm soil layer, prolongs peak time at this time
4 minutes or so；In terms of reservoir storage, when covering 20cm and following soil layer, Green Roof reservoir storage near 5 years one chance rainfall intensities
Percentage highest, storing stagnant percentage when higher or lower than this raininess has different degrees of reduction, and when soil layer reaches 30cm, 10
It meets in year one under condition of raining and stores stagnant percentage highest.So in general, the light-duty water penetration Green Roof with soil layer 5 to
Ability is not fully exerted under chance rainfall in 10 years one, and more than this raininess, it stores stickiness and different degrees of can decrease.
