As shown in Figures 1 to 4, the rapid recovery structure of building sewage in this embodiment includes a recovery box 1, a partition 5 laid on the top of the recovery box 1, a permeable brick layer 2 laid on the top of the partition 5, a crushed stone layer 3 laid around the recovery box 1, and a natural soil layer 4 below the crushed stone layer 3. The permeable brick layer 2 is paved with a plurality of permeable bricks. There is a water seepage gap in the middle of the permeable bricks, and rainwater can be used to penetrate downward. Mud discharge grooves 8 are opened at the edges of the bottom surface of the inner cavity of the recovery box 1. The bottom surface of the mud discharge groove 8 is lower than the recovery box 1, which is used to store the precipitated granular impurities and silt in the recovery box 1. The bottom surface of the inner cavity of the recovery box 1 is inclined from the middle to the surroundings to form a slope 7, which is used to guide the precipitated granular impurities and silt into the mud discharge groove 8. Drainage ports 9 are opened through the two side walls of the recovery box 1 to drain water when there is too much water stored in the recovery box 1. Entering the gravel layer 3, a water retaining curtain 10 is arranged inside the drain outlet 9, and the water retaining curtain 10 is used to close the drain outlet 9. The water retaining curtain 10 is bent in a W shape and can be extended and retracted longitudinally. A fixed plate 11 is connected to the top of the drain outlet 9, and the fixed plate 11 is fixed to the top of the drain outlet 9. A movable plate 12 is connected to the bottom of the water retaining curtain 10. A connecting block 13 is connected to one side of the movable plate 12. A floating ball 14 is connected to the top of the connecting block 13. The bottom of the floating ball 14 is connected to the movable plate 12 through the connecting block 13. After the water level in the recovery box 1 reaches the height of the floating ball 14, the floating ball 14 is pushed to move up. A drain pipe 17 is arranged through the rear side wall of the recovery box 1. There are two drain pipes 17. The two drain pipes 17 converge and are connected to the water storage tank 6. The end of the drain pipe 17 away from the recovery box 1 is connected to the water storage tank 6 for collecting recycled sewage.

Specifically, slide grooves 23 are provided on the inner walls on both sides of the front and rear of the drain outlet 9, and the front and rear sides of the movable plate 12 protrude to form a cross shape. The front and rear sides of the movable plate 12 are inserted into the slide grooves 23, and the front and rear sides of the movable plate 12 are inserted into the slide grooves 23 to form a sliding connection. The movable plate 12 forms a sliding connection with the drain outlet 9, and the fixed plate 11 is connected to the top of the drain outlet 9. The movable plate 12 moves up in the drain outlet 9, and the movable plate 12 pushes the water retaining curtain 10 to shrink and move up, so that the drain outlet 9 is opened. During actual use, there is a gap between the front and rear side walls of the water retaining curtain 10 and the inner wall of the drain outlet 9, and the gap allows sewage to flow. When the water level reaches the bottom of the water retaining curtain 10, the water level has overflowed the drain pipe 17. At this time, the water level in the water storage tank 6 has exceeded the filter plate 18 and is full. Therefore, a small amount of water seepage on the front and rear sides of the water retaining curtain 10 has no effect.

Furthermore, a collar 15 is connected to one side of the float 14, and a vertical rod 16 is provided through the middle of the collar 15. The collar 15 connects the float 14 and the vertical rod 16, and the bottom of the vertical rod 16 is connected to the slope 7. The vertical rod 16 penetrates the collar 15 and forms a movable connection with the collar 15. The collar 15 and the vertical rod 16 are connected to limit the float 14, so that the float 14 only has a tendency to move vertically when it is affected by the buoyancy of water.

Furthermore, the mud discharge trough 8 is in the shape of a rectangular frame, and the mud discharge trough 8 is connected to the inner cavity of the recovery box 1. The slope 7 is in the shape of a four-sided pyramid and is inclined in all directions. The lowest point of the slope 7 is flush with the top of the mud discharge trough 8. Rainwater penetrates downward through the permeable brick layer 2 and is stored in the recovery box 1. The particulate impurities and silt in the rainwater are precipitated on the slope 7, and the particulate impurities and silt flow into the mud discharge trough 8 along the inclined slope 7 and are collected.

Furthermore, a filter plate 18 is provided inside the water tank 6. The clarified water after sedimentation can be stored in the water tank 6 only after being filtered through the filter plate 18. A water storage chamber 19 is provided below the filter plate 18, and a sealed chamber 20 is provided above the filter plate 18. A water pump 21 is installed inside the sealed chamber 20. The water pump 21 is used to pump water out of the water storage chamber 19 for use. The water pump 21 can be powered by photovoltaic power supply or by connecting to underground cables. Both ends of the water pump 21 are connected to external pipes 22. The user can directly collect water at the top of the external pipe 22, or connect a water pipe to the external pipe 22 for water use. The water storage chamber 19 is connected to the recovery tank 1 via the drain pipe 17.

Furthermore, the vertical height of one end of the drain pipe 17 connected to the recovery tank 1 is higher than that of the end connected to the water storage tank 6. When the water level in the recovery tank 1 reaches the drain pipe 17, clarified water will automatically flow from the drain pipe 17 into the water storage tank 6. The height at which the drain pipe 17 connects to the recovery tank 1 is between the slope 7 and the lowest height of the float 14. When the amount of seepage is small, the sewage is left to settle in the recovery tank 1. When the water level of the seepage reaches the drain pipe 17, the sewage in the recovery tank 1 begins to flow into the water storage tank 6 for recycling. When the amount of seepage is higher than the lowest position of the float 14, the drain port 9 opens and begins to drain water to the outer gravel layer 3, which is suitable for sewage recovery in weather with different rainfall amounts.

The method of using this embodiment is as follows: when the user actually applies the sewage rapid recovery structure to the road green building, the user first installs the recovery box 1 in the road gravel layer 3, embeds the water storage tank 6 in the gravel layer 3, connects the recovery box 1 and the water storage tank 6 by the drainage pipe 17, lays a partition 5 above the recovery box 1, and then lays a permeable brick layer 2 above the partition 5. In rainy weather, the rainwater penetrates downward through the permeable brick layer 2 and flows into the recovery box 1. The particulate impurities and mud and sand in the rainwater settle on the slope 7 and flow into the mud discharge trough 8 along the inclined slope 7. When the rainwater storage level reaches the height of the drainage pipe 17, the clarified water at the top flows from the drainage pipe 17 into the water storage tank 6, and the clarified water is filtered by the filter plate 18 and stored in the water storage cavity 19, the user can connect a water pipe to the external pipe 22 on the road surface, turn on the water pump 21 to pump out the water in the water storage chamber 19 for urban greening maintenance, high-pressure washing of traffic roads, water for dust removal on construction roads and water for fire fighting. After the water storage tank 6 is full of water, the water level in the recovery box 1 rises to the lowest position of the float 14, and the float 14 rises with the water level. The float 14 drives the movable plate 12 to move up in the drain outlet 9 through the connecting block 13, and the ring 15 moves up on the outside of the vertical rod 16. The movable plate 12 drives the water retaining curtain 10 to shrink upward, so that the drain outlet 9 is opened for drainage, and the excess sewage is discharged from the gravel layer 3. The cross-sectional area of the drain outlet 9 increases with the rising water level, and the drainage speed is automatically adjusted according to the water level in the recovery box 1 to ensure that there is no water accumulation on the surface of the permeable brick layer 2.

Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
