DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The present utility model will be further described in detail below with reference to the drawings and through embodiments. The following embodiments are explanations of the present utility model and the present utility model is not limited to the following embodiments.
[0017] This embodiment is a tree pool structure on an urban ground. When constructing the basement, a foundation pit 9 is reserved on the ground above the basement, and a waterproof blanket 10 is laid in the foundation pit 9 to prevent the stored water in the foundation pit 9 from leaking into the basement.
[0018] In this embodiment, a tree pit body 1 is arranged in the foundation pit 9. A concrete partition 4 is arranged in the tree pit body 1. At least three concrete piers 5 are arranged below the concrete partition 4. The concrete piers 5 play a supporting role for the concrete partition 4. The concrete partition 4 divides the tree pit body 1 into an upper area and a lower area. A soil layer 2 is filled in the upper area of the tree pit body 1, and trees can be planted in the soil layer 2. The lower area of the tree pit body 1 is a water isolation layer 6. At least two second drainage holes 8 are arranged on the concrete partition 4. A filter bag 7 is arranged at a position corresponding to the second drainage holes 8 above the concrete partition 4. The filter bag 7 is composed of gravel wrapped by permeable geotextile. Thus, when there is a lot of accumulated water in the soil layer 2 in the upper area of the concrete partition 4, the excess accumulated water can be discharged into the water isolation layer 6 in the lower area of the concrete partition 4 through the second drainage holes 8. Under the action of the filter bag 7, soil loss in the soil layer 2 of the tree pit body 1 can be avoided. A first drainage hole 3 is made on the side wall of the lower area of the tree pit body 1, which is convenient for discharging the stored water in the lower area of the tree pit body 1 into the foundation pit 9.
[0019] In this embodiment, a submersible pump 11 is arranged in the foundation pit 9. The water outlet pipe 12 at the outlet end of the submersible pump 11 is communicated to the outside of the foundation pit 9. When the submersible pump 11 operates, the stored water in the foundation pit 9 can be discharged. Further, the water outlet pipe 12 is communicated to a rainwater well, which is convenient for directly discharging the stored water in the foundation pit 9 into the rainwater well.
[0020] In this embodiment, a liquid level gauge 14 is also arranged in the foundation pit 9. The liquid level gauge 14 can obtain the water level information in the foundation pit 9. Both the liquid level gauge 14 and the submersible pump 11 are communicatively connected to a controller 15. The liquid level gauge 14 can send the obtained water level information into the controller 15. When the obtained water level information in the controller 15 reaches the high value preset by the controller 15, the controller 15 controls the submersible pump 11 to operate and discharge the accumulated water in the foundation pit 9. After the accumulated water in the foundation pit 9 is discharged to a certain amount, when the obtained water level information in the controller 15 reaches the low value preset by the controller 15, the controller 15 controls the submersible pump 11 to stop operating, realizing the automatic discharge of the stored water in the foundation pit 9.
[0021] In this embodiment, a maintenance cover plate 13 is laid on the surface of the foundation pit 9. Thus, it is convenient to open the maintenance cover plate 13 to maintain the equipment in the foundation pit 9.
[0022] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
