5 illustrates an example in which the drain pipe 70 is linearly connected to the water collecting well 3, but the water drain pipe 70 may be freely angularly deformed, regardless of the position of the previously installed water collecting well 3. The main body 10 can be freely connected.

At this time, if necessary, it is also possible to connect the rainfall outflow water inlet pipe to the main body 10 separately.

The vegetation (P) to be planted in the main body 10 is laminated to the lower layer filter layer 42 and the soil layer 50 in the planting and filtering space (S1) of the main body 10, the upper layer filter layer 41 It is planted in the soil layer 50 before laminating, and then the upper layer filtering layer 41 is laminated on the soil layer 40.

In addition, the manhole or the sump (3) can be installed in advance before using the existing installation or planting the tree planting box according to the invention.

Rainfall runoff water generated during the rain in the installation is completed, the overflow of the front and rear walls 12, 13 and the left and right walls 14, 15 of the tree planting box body 10 to the planting and filtering space (S1) Inflow.

Rainfall effluent flowing into the planting and filtration space (S1) is filtered downward while passing through the upper filter layer (41), and the rainfall effluent passing through the upper filter layer (41) is the soil layer (50) It is filtered downward while passing downward, and is filtered downward downward while passing downwardly through the lower media layer 42.

Rainfall outflow water filtered downward through the lower media layer 42 is filled from the bottom of the planting and filtration space (S1).

Rainfall runoff from the bottom of the planting and filtration space (S1) is again filtered through the bottom filter layer 42 and the soil layer 50 and the upper filter layer 41 upward again.

Thus, the rainfall runoff flowing into the planting material and the filtration space (S1) of the main body 10 is filtered downward while passing downward through the upper media layer 41, the soil layer 50 and the lower media layer 42, It is filtered from the bottom of the planting material and the filtration space (S1) of the main body 10 is filtered upward to remove the non-point pollutants contained in the rainfall effluent sufficiently.

That is, in the case of the initial rain with a high content of non-point pollutants, the non-point pollutants are filtered out by the natural flow in the main body 10.

Here, when the water level of rainfall runoff rising from the lower end of the planting and filtration space (S1) of the main body 10 reaches the upper media layer 41 and the overflow passage 60, the rainfall runoff flows through the overflow passage 60 The water flows through and flows into the water collecting space S2 of the water collecting chamber 20 to be collected.

At this time, since the filter medium 61 is provided at the inlet side of the overflow passage 60, the non-point contaminant such as the suspended solids collected in the upper filter layer 41 is introduced into the collecting space S2. After filtration once more by the flow into the collecting space (S2) of the collecting chamber (20).

Therefore, the non-point pollutant is sufficiently removed in the rainfall effluent collected in the collecting space S2 of the collecting chamber 20.

When this process has elapsed, a certain time passes and the rainwater contains less nonpoint source than the initial rainwater, and the rainwater flows directly because the planting material and the filtration space S1 of the main body 10 are saturated. The water flows through the passage 60 and flows into the water collecting space S2 of the water collecting chamber 20.

That is, after a certain time has elapsed in the initial rainwater, the rainwater containing less nonpoint source naturally passes only through the filter medium 61 of the overflow passage 60 so as to flow into the collection chamber 20 to be discharged to the outside. It is possible to increase the treatment efficiency of nonpoint source through natural rainwater flow.

On the other hand, when the rainfall continues, or the rainfall runoff is rapidly increased due to heavy rain, the water level of the rainfall runoff flowing into the planting and filtering space (S1) of the main body 10 is higher than the upper end of the main body side wall 13, the main body Rainfall outflow water introduced into the planting and filtration space (S1) of (10) flows into the collection space (S2) by overflowing the collection chamber (20). Therefore, even if the rainfall runoff increases rapidly, the rainwater can be stored and discharged in the main body 10 and the collection chamber 20, thereby preventing flooding.

Even in this case, the rainfall effluent flows directly into the collecting space S2 of the collecting chamber 20 without undergoing the downward filtration process and the upward filtration process as described above.

The rainfall outflow water introduced into the collection space S2 of the collection chamber 20 is drained to the manhole or the sump 3 through the drain pipe 70. On the other hand, as shown in Figure 6 in the case where deformation occurs in the ground due to the loading load, such as the upper portion of the drain pipe (70) pre-installed (down direction in the drawing), the drain pipe 70 is attached pipe 710 and fastening pipe ( Since 750 is configured to be deformed to some degree, it is possible to accommodate deformation of the ground.

That is, after construction, an abnormality may occur in the drain pipe (drainage line) that is already embedded due to the deformation of the ground, thereby controlling problems such as rainfall leakage from the main body 10 and the collection chamber 20 that leak directly to the ground.

On the other hand, according to an embodiment of the present invention, the collecting chamber 20 is lower, that is, the bottom plate body 21 of the collecting chamber 20, the collecting and filtering of the collecting space (S2) and the main body 10 One or more pitcher passages 80 communicating with the space S1 may be further included.

The water permeable passage 80 may be composed of a plurality of perforation holes perforated in the bottom plate body 21 of the collection chamber 20, or may be composed of a plurality of water permeable pipes penetrating the bottom plate body 21.

Rainfall outflow water introduced into the collection space (S2) of the collection chamber 20 is drained to the outside through most of the drain passage 70, but a part of the planting of the main body 10 again through the water passage passage (80) It is provided as water necessary for vegetation of the vegetation (P) planted in the soil layer 50 is stacked in the filtration space (S1) to ensure sufficient moisture for the growth of planted vegetation (P) plant (P) can grow actively.

In addition, according to an embodiment of the present invention, the body 10 may further include a ground permeable passage 90 communicating with the ground at the bottom thereof, that is, the bottom plate body 11 of the body 10. The underground water passage 90 is to allow the rainwater discharged water remaining in the planting material and the filtration space (S1) of the main body 10 into the ground, an excessively large amount in the planting and filtration space (S1). Rainfall runoff is to prevent the long-term retention of the planted tree (P) due to excessive moisture.

The underground water passage 90 may be composed of a plurality of underground water holes perforated in the bottom plate body 11, or may be composed of underground water pipes penetrating the bottom plate body 11.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of the invention.
