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.COPYRIGHT KIPO 2013본 발명은 측구집수조와 가로수목 식재박스를 일체형으로 구성하여 별도의 배관이 필요가 없어 지반침하 등에 의해 배관고장으로 물순환라인에 문제가 생기는 것을 방지할 수 있으며, 일체형 시공에 의해 시공경제를 도모하고, 도로의 수목 공간을 활용하여 물순환 환경을 구축함과 아울러 비점오염물질의 효율적인 처리가 가능한 가로수목 식재박스에 관한 것이다.
