It is arranged at intervals with multiple interception dams 4 in grass planting ditch 1 and along its length, and intercepts dam 4 and is parallel to grass planting ditch 1
Width direction, by intercept dam 4 to 1 subregion of grass planting ditch.
When rainwater is larger, if the osmotic effect for relying only on planting soil layer 11 is drained, can be deposited on its surface
A large amount of water, to generate immersion to external plant.In order to which internal ponding is discharged, the row of offering on intercepting dam 4
Sink 41, and rhone 41 be arranged it is " T " shape, horizontal both ends be respectively communicated with intercept dam 4 horizontal two sides, and formed draining
Mouth 411, vertical one end of rhone 41 is through the bottom for intercepting dam 4.
Meanwhile excessive soil enters in rhone 41 in order to prevent, the height of discharge outlet 411 should be higher than planting soil layer
11 upper surfaces, so as to be filtered to particles such as soil, at the same time, discharge outlet is provided with the first filtering at 411 position
Net 42 can be filtered floating material by the first filter screen 42.
Arrangement offers multiple draining holes 21 on curb 2, rainwater can be made to flow to grass planting ditch 1 by draining hole 21
It is interior, while the second filter screen 22 is fixedly connected in each draining hole 21, the both ends of the second filter screen 22 are fixedly connected on
When curb 2, while end face and curb 2 end face far from grass planting ditch 1 of second filter screen 22 far from grass planting ditch 1 is positioned at same
In plane, rubbish and sediment in rainwater is made to be not easy to build up in the place close to the second filter screen 22 at this time.Simultaneously
Close to draining hole 21 grass planting ditch 1 on by be laid with cobble after be formed with buffer layer 23, so as to by draining hole 21 into
Enter to the rainwater on grass planting ditch 1 and is buffered.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
