[0002] The sponge city is a kind of technology of urban rainwater resource management, which means that the city can recycle excess rainwater and reuse it like a sponge. The grass pavement device with rainwater recycling function is a good equipment for building a sponge city, and also can beautify the city.

[0003] In order to prevent dry grass and sand and other sundries from entering the water storage container on the existing grass pavement structure, a filter screen for interception is usually covered on the water inlet groove. The filter holes of the filter screen are easily blocked by sand and other sundries after a long time of use. The existing filter screen is usually arranged in a flat manner, so that the sundries under interception are easily attached to the flat filter screen, resulting in good adhesion stability between the sundries and the filter screen, which is difficult to be cleaned and removed. In addition, the flat filter screen is usually cleaned and unblocked by beating and vibrating, which causes great damage to the filter screen. SUMMARY

There are two settling tanks, and two long sludge discharge channels are symmetrically opened at the bottom of the left and right side walls of the rainwater storage tank. The two long sludge discharge channels are connected to the two settling tanks. Two sludge collection channels are inserted into the two settling tanks. Four springs are symmetrically slidably installed on the front and rear ends of the two longitudinal track shafts. The four springs push against the front and rear side walls of the planting tray, and the four springs push the planting tray and the front and rear side walls of the top opening of the rainwater storage tank to form two long water inlet channels. Two metal filter screens are symmetrically covered and installed on the openings of the two long water inlet channels by screws. A horizontal support positioning shaft is welded to the bottom of the front space of the rainwater storage tank, and two scrapers are symmetrically slidably installed on the horizontal support positioning shaft.

[0006] Furthermore, the settling box is composed of three parts: upper, middle, and lower. The upper and lower parts are rectangular, while the middle part is trapezoidal with outward expansion on both the front and back sides. The mud-holding trough is slidably inserted into the rectangular space of the lower part of the settling box.

[0007] Furthermore, four vertical support plates are symmetrically welded at the four corners of the top of the mud-holding trough, and a strip cover plate is horizontally welded to the top of the four vertical support plates. The strip cover plate is inserted into the top opening of the rectangular space above the settling box, and a pull shaft is welded at the center of the top of the strip cover plate.

[0008] Furthermore, a double-threaded shaft is rotatably installed at the bottom of the front space of the rainwater storage tank, adjacent to the front of the cross brace positioning shaft.

The two metal filter screens are in an upward arched support, which makes it difficult for the filtered impurities to be flatly attached to the filter screens, so that a large gap or spacing is formed between the impurities and the filter screens, thereby reducing the stability of the impurities attached to the filter screens, and compared with the flatly arranged filter screens, the filtered impurities are more easily and simply removed, and the elastic deformation of the peripheral frames of the two metal filter screens enables the two metal filter screens to be frequently switched between the curved arched state and the horizontal expanded state along the two longitudinal track shafts, so that the filter screen body and the filter holes are continuously deformed, the filtered impurities on the filter screen are loosened, and the sand and soil blocking the filter holes are loosened, compared with the conventional way of cleaning the filter screen by hammering and vibrating, the damage to the filter screen is effectively reduced, and the convenience of cleaning the filtered impurities on the filter screen is improved.

[0016] 2. In a conventional use state, the two abutting scrapers are centrally slid and spliced together to form a closed space, and the L-shaped extraction pipe is covered in the closed space, so that the settled soil in the rainwater storage tank is prevented from directly falling on the bottom opening of the L-shaped extraction pipe, the probability of the L-shaped extraction pipe being blocked is maximally avoided, and the frequency of subsequent cleaning of the L-shaped extraction pipe is greatly reduced.

[0017] 3、The positive and reverse rotation of the double-rotation screw shaft directly pushes and drives the two scraping plates to slide against each other to scrape and clean the settled soil at the bottom of the rainwater storage tank, and pushes and scrapes the settled soil into the two settling tanks, so that the settled soil in the storage tank can be directly scraped and cleaned without disassembling and opening the water storage device, and the cleaning operation of the settled impurities is simple and time-saving.

[0018] 4、The settled impurities pushed and scraped into the two settling tanks fall into the two mud storage grooves, and the settled impurities collected in the two mud storage grooves can be directly extracted by lifting the strip-shaped cover plate without disassembling and opening the water storage device, so that the settled impurities can be taken out and unloaded simply and time-savingly.
