As shown in fig. 1 to 3, a rainfall drainage structure for construction includes a drainage tank 10, an upper filter plate 60, a drainage header 30, a liquid level sensor 70, and an auxiliary drainage mechanism.

The drain tank 10 has a hollow structure. The upper filter plate 60 is disposed at a water inlet formed at the top of the drain tank 10, and the upper filter plate 60 is vertically perforated with a plurality of water permeable holes. A drain main 30 is connected to the bottom of the drain tank 10. The liquid level sensor 70 is provided at the inside top of the drain tank 10.

The auxiliary drainage mechanism comprises a water pump 21, a filter box 22, a water pumping main pipe 23 and a water pumping branch pipe 24. The water pump 21 is connected outside the drainage box 10 through a bolt, a drainage branch pipe 25 is connected between the water pump 21 and the drainage main pipe 30, and the water pump 21 and the liquid level sensor 70 are electrically connected with the control unit. The filter tank 22 is arranged at the top in the drain tank 10, and the filter tank 22 is connected with the water pump 21. The water suction manifold 23 is horizontally connected to the side wall of the filter tank 22. The pumping branch pipes 24 are vertically connected to the bottom end of the pumping header pipe 23. The number of the pumping branch pipes 24 is plural.

The bottom of the drainage box 10 is obliquely provided with a guide plate 40 for guiding water to the drainage main pipe 30, so that rainwater can be conveniently drained.

The filtering components 50 are further arranged between the bottom of the upper filtering plate 60 and the guide plate 40, the filtering components 50 are arranged at intervals along the horizontal direction, the adjacent filtering components 50 divide the drainage box 10 into a plurality of water storage cavities 11, and the water pumping branch pipes 24 are arranged in the water storage cavities 11. Rainwater penetrates through the upper filter plate 60 and enters the water storage cavity 11, then the rainwater flows into the drainage main pipe 30 along the guide plate 40 and then is discharged underground, and the filtering component 50 can filter impurities and dust in the rainwater, so that the pollution to underground water is avoided.

The filter assembly 50 includes a frame plate 51, a filter net 52 and an activated carbon net 53, the frame plate 51 is two horizontal plates, the filter net 52 is vertically connected between the frame plates 51, and the activated carbon net 53 is disposed in a cavity formed by the frame plates 51 and the filter net 52.

The top of the filter box 22 is movably connected with a cover plate 26, the bottom of the cover plate 26 is connected with a filter element 28, and the top of the cover plate 26 is connected with a handle 27. The filter cartridge 28 is removably attached to the bottom of the cover plate 26, such as by bolting or the like.

The working principle of the construction rainfall drainage structure is as follows: the rainwater enters the water storage cavity 11 through the upper filter plate 60, then flows into the drainage main 30 along the flow guide plate 40, and then is discharged underground. When the rainfall is excessive, the automatic drainage speed of the rainwater in the drainage tank 10 is too slow, so that the rainwater in the drainage tank 10 may rise. When rainwater contacts the liquid level sensor 70, the control unit controls the water pump 21 to start working, and the water pump 21 can pump rainwater in the water storage cavity 11 to the water pumping branch pipe 24, then the rainwater is concentrated to the water pumping main pipe 23, then the rainwater enters the filter box 22, is treated by the filter element 28, then enters the water drainage main pipe 30 through the water drainage branch pipe 25, and finally is drained to the ground. After the filter element 28 is used for a period of time, the cover plate 26 can be taken down, then the filter element 28 is taken out, and then the filter element 28 is cleaned or replaced, so that people can clean and replace the filter element 28 conveniently, and the filter effect is prevented from being influenced due to the fact that the filter element 28 is not cleaned for a long time.

The above embodiments are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims.
