Detailed ways

The present utility model will be further described below with reference to the accompanying drawings and specific embodiments. The terms such as "up", "down", "left", "right", "middle" and "one" quoted in the preferred embodiment are only for the convenience of description and are not used to limit the present invention. The practicable scope and the change or adjustment of the relative relationship thereof shall also be regarded as the practicable scope of the present invention without substantially changing the technical content.

As shown in FIG. 1, a water storage tree pond includes a tree pond body excavated in the base soil 1, the bottom of the tree pond body is a water storage area, and the water storage area is composed of a water storage tank 10 and a water storage tank 10 filled with it. The first sand and gravel 9 of coarse particles in the water storage area is composed of a sand filter layer formed by laying a second sand and gravel 11 of fine particles above the water storage area. In the planting layer, with the production of the four root systems of the trees, they will gradually penetrate downward. The first gravel 9 in the water storage tank 10 is coarse particles, with large gaps and strong water storage capacity, and is downward from the planting layer and the sand filter layer. The infiltrated surface water can be collected in the water storage tank 10 to provide water for the growth of the trees 4 .

Below or on the side of the water storage area, there is a drainage pipe 7 that communicates with the municipal irrigation canal, and a horizontal or inclined filter pipe 8 is buried in the sand filter layer. The pipe wall of the filter tube 8 in the filter layer is provided with a number of small filter holes. When it rains for a long time or there is a lot of surface water, when the water infiltrating the water storage tank 10 is full, the base soil 1 cannot seep out through the excess water at the same time. At this time, a large amount of water will accumulate in the tree pond body, and if the water content of the sand filter layer is too high, it will penetrate into the filter pipe 8 through the small holes on the pipe wall of the filter pipe 8, and then be discharged through the drain pipe 7. At the same time, the sand filter layer also has the ability to filter sewage.

The thickness of sand is divided into four grades: coarse, medium, fine and extra-fine according to the fineness modulus (μf). Fine sand: μf=2.2～1.6; Extra-fine sand: μf=1.5～0.7. It should be noted here that the coarse particles in the present invention correspond to the size range of coarse sand, and the fine particles are the size range of fine sand.

The surface of the planting layer is lower than the hardened ground 6 on the base soil 1, the surface of the planting layer is provided with an overflow pipe 5 communicating with the drainage pipe 7 downward, and the upper end of the overflow pipe 5 is higher than the surface of the planting layer and lower than the surface. On the hardened ground 6 on the base soil 1, since the surrounding of the tree pond body is the hardened ground 6, when the rainwater flowing to the tree pond body is greater than the seepage velocity of the filter pipe 8, it is easy to make the surface of the planting layer and the entire hardened ground 6 accumulate a lot. At this time, the accumulated water on the surface of the planting layer can flow into the drainage pipe 7 through the overflow pipe 5, and then be discharged to the municipal irrigation channel through the drainage pipe 7, which effectively prevents the problem of surface water accumulation.

In a specific implementation, the depth of the water storage tank 10 is 100 to 300 mm, the first sand and gravel 9 is filled in the groove of the water storage tank 10, the diameter of the drain pipe 7 is not less than 100 mm, and the diameter of the filter pipe 8 is not less than 100 mm. 50mm, and the diameter of the overflow pipe 5 is not less than 50mm.

Preferably, the outer wall of the filter tube 8 in the sand filter layer is wrapped with filter cloth or sponge, and the filter cloth or sponge can prevent the second grit 11 of the sand filter layer from clogging the small holes on the filter tube 8 . The upper end nozzle of the overflow pipe 5 is provided with a filter grate, which can prevent garbage from clogging the nozzle of the overflow pipe 5 .

As a further preferred solution of the present embodiment, the surface of the planting layer is further provided with a nutrition tube 2, the upper end of the nutrition tube 2 is exposed above the surface of the planting layer, and the lower end of the nutrition tube 2 is inserted into the water storage tank 10. In the first gravel 9, the nutrient solution can be put into the water storage tank 10 through the nutrient pipe 2, so that the trees 4 can fully absorb it. In addition, when drought occurs, water can also be injected into the water storage tank 10 through the nutrient pipe 2, which can save more water than ground watering.

In a specific implementation, the surface of the planting layer is further provided with a covering layer that is flush with the hardened ground 6 on the base soil 1, and the covering layer is gravel or grid.

Although the specific embodiments of the present utility model have been described above, those skilled in the art should understand that these are only examples, and various changes or modifications can be made to the present embodiments without departing from the principles and essence of the present utility model. The protection scope of the present invention is limited only by the appended claims.
