A STREET TREE BOX HAVING FUNCTION OF SINKING PREVENTION

摘要

PURPOSE: A roadside tree planting box is provided to simultaneously treat non-point pollutants, and to be able to prevent the settlement due to the subsidence of neighboring ground. CONSTITUTION: A main body(10) is open on the top, and formed with a planting and filtering space(S1) inside. A collecting chamber(20) has an overflow path which connects the upper part of the planning and filtering space and a collecting space(S2), and a drain gutter(70) which drains the inflow water of the collecting space. A subsidence prevention frame(100) is installed around the main body. A plant vegetation layer(30) is laminated in the planting and filtering space. The subsidence prevention frame comprises to form a lattice structure with multiple horizontal frames and multiple longitudinal frames. A mesh net is formed on the lattice formed by the horizontal frames. An upper medium layer(41) and a lower layer medium layers(42) 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.
