FIG. 1 is a schematic structural diagram of the present invention.

In the figure: the rainwater grate comprises a rainwater grate 1, a sewage intercepting hanging basket 2, a coarse sand layer 3, a fine sand layer 4, a drainage coiled material 5, a waterproof layer 6, a leveling layer 7, a concrete top plate 8 and a planting soil layer 9.

Detailed Description

In order to make the technical means, the original characteristics, the achieved purpose and the efficacy of the utility model easy to understand, the utility model is further described with reference to the specific drawings.

As shown in fig. 1, a formula of sinking ecological collection device of rainwater, including the device body, the device body is a collection well, rainwater grate 1 that sets gradually from top to bottom in the collection well, cut dirty string basket 2, coarse sand layer 3 and fine sand layer 4, collection well top exit is provided with the hoop recess, rainwater grate 1 and cut dirty string basket 2 both edges all are located the hoop recess, collect the well below and set gradually drainage coiled material 5, waterproof layer 6, screed 7 and concrete roof 8 (waterproof layer 6 and screed 7 can refer to application number CN200810018442.3, waterproof layer and screed mentioned in, drainage coiled material 5 top is planting soil layer 9, the collection well runs through planting soil layer 9 along the perpendicular to horizontal direction.
