Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Refer to fig. 1, do the utility model discloses a water conservancy grass planting ditch structure, including planting the layer for plant the grass. The bottom of the planting layer 1 is provided with a filter layer 2 for filtering rainwater seeping from the planting layer 1. The bottom of the filter layer 2 is provided with a drainage layer 3 for draining rainwater filtered by the filter layer 2.

Referring to fig. 1, planting layer 1 is close to the even interval in top part and is provided with a plurality of drain pipes 4, and drain pipe 4 extends along the length direction who plants layer 1, and drain pipe 4 top is provided with a plurality of collector pipes 5 along the even interval of length direction for collect the rainwater at planting layer 1 top. The drain pipe 4 is communicated with an external drain ditch and is used for draining rainwater collected by the water collecting pipe 5 into the drain ditch.

Referring to fig. 1 and 2, the top of the water collecting pipe 5 is flush with the top of the planting layer 1, which is beneficial for rainwater on the top of the planting layer 1 to enter the water collecting pipe 5. The filter screen 9 is sleeved on the periphery of the top of the water collecting pipe 5, so that sundries, hay and the like in rainwater can be prevented from entering the water collecting pipe 5. Preferably, the filter screen 9 is preferably a non-woven fabric, and is sleeved on the top of the water pipe in a binding manner.

Referring to fig. 2 and 3, during installation, the water collecting pipes 5 are respectively installed on the water discharging pipes 4, then the filter screen 9 is sleeved on the tops of the water collecting pipes 5, then the installed water discharging pipes 4 and the water collecting pipes 5 are placed and installed on the planting layer 1 when the planting layer 1 is laid to a certain height, finally the laying of the planting layer 1 is continued, and the tops of the water collecting pipes 5 are flush with the tops of the planting layer 1 when the laying is completed.

Referring to fig. 1, the filtering layer 2 is of a pebble structure, which is beneficial to increasing the penetration speed of rainwater and can filter soil. A plurality of water drainage tank 6 have been seted up at the even interval in drainage blanket 3 top, and water drainage tank 6 extends along drainage blanket 3's length direction. The vertical cross section of the drainage channel 6 is of a circular arc-shaped structure, and the arc-shaped convex part faces downwards vertically, so that rainwater collected by the drainage channel 6 can be collected to the middle part of the bottom of the drainage channel 6.

Referring to fig. 1, a plurality of water outlet pipes 7 are uniformly arranged at intervals along the length direction in the middle of the bottom of the drainage groove 6, the water outlet pipes 7 are communicated with the drainage groove 6, and one side, away from the drainage groove 6, of each water outlet pipe 7 is communicated with an underground sewage pipeline for draining rainwater collected by the drainage groove 6. The top of the drainage layer 3 is provided with a geotextile layer 8 for filtering rainwater from the filter layer 2 and reducing the loss of soil.

Referring to fig. 1, a plurality of conveying pipes 10 are uniformly arranged on the planting layer 1 along the length direction at intervals, and the plurality of conveying pipes 10 are respectively positioned between two adjacent water drainage pipes 4. The top of the conveying pipe 10 penetrates through the planting layer 1 to the outside, so that the height of the top of the conveying pipe 10 is higher than that of the top of the planting layer 1, and the bottom of the conveying pipe 10 penetrates through the planting layer 1 and extends to the top of the filtering layer 2. The collection rate of collecting the rainwater when collector pipe 5 is not enough for when the rainwater of planting layer 1 top rises, transmission pipe 10 is collected the ponding that rises in a burst, makes rainwater direct transmission to filter layer 2, is favorable to promoting the drainage ability of planting layer 1.

The use principle is as follows:

referring to fig. 1 and 2, when raining, rainwater falls on the top of the planting layer 1, wherein a part of rainwater permeates through soil, is finally filtered by the filter layer 2, is collected by the drainage groove 6, and is drained through the water outlet pipe 7. The other part of the rainwater is filtered by the filter screen 9 and then enters the water collecting pipe 5, and then the collected rainwater is drained by the water draining pipe 4. When the drainage efficiency of rainwater is not enough for the rainwater rises, the rainwater gets into transmission pipe 10, then directly transmits to filter layer 2 and filters, flows to drainage layer 3 again and excretes. The whole process is simple, and the drainage capacity of the grass planting ditch is favorably improved.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
