<p>A planter structure for street trees of the present invention comprises: an upper space (A) which collects rainwater from the top and temporarily stores the collected rainwater; an undercurrent space (B) which is disposed in a lower part of the upper space to store the collected rainwater such that the rainwater can slowly infiltrate into the soil; and a soil space (C) which is formed toward the inside of the upper space and the undercurrent space, and which is filled with soil for planting. The upper space (A) is filled with filter media so as to purify the collected rainwater. One or more multipurpose filters (151, 152) adaptable to climate changes are arranged to supply the rainwater stored in the soil space (C) such that the rainwater stored in the undercurrent space (B) can be slowly supplied to roots of a planted tree for a long time by connecting the undercurrent space (B) with the soil space (C). The planter structure for street trees further includes a steel grating (200) which can cover the upper space (A) after a tree is planted in the soil space (C).</p> |
