PURPOSE: A technique is provided to be able to simultaneously treat non-point pollutants, and to build with integrating a road tree planting box with a gutter collecting bath. CONSTITUTION: A main body(10) is open on the top, and formed with a planting and filtering space(S1) inside. A gutter collecting bath(20) has an overflow path(60) and a drain gutter(70) which drains the inflow water of a collecting space. A plant vegetation layer(30) is laminated in the planting and filtering space. The overflow path connects the top of the planting and filtering space and the collecting space. The gutter collecting bath integrally comprises in a lower position than the main body, and the upper end of a side wall of the main body is connected to the sidewalk(R1). The upper end of a side wall(22) of the gutter collecting bath comprises to connect to the gutter. The main body and the gutter collecting bath are partitioned by an internal partition wall(12), and the internal partition wall is connected to a curb. An upper medium layer and a lower medium layers are respectively laminated on the upper and lower parts of the planting and filtering space. A soil layer(50) is laminated between the upper and lower medium layers. |
