Integrated open kerb with diversion trench
The invention relates to an integrated open kerb with a diversion trench, and belongs to the technical field of rainwater treatment. The integrated open kerb comprises a W-shaped rainwater grate, a variable slope type diversion trench and an open kerb, and the open kerb is provided with a cut-in notch penetrating through the two sides of the open kerb; a variable slope type flow guide groove is formed in the road on one side of the cut-in notch; the variable slope type diversion trench is covered with the W-shaped rainwater grate; the two faces of the variable slope type diversion trench are both of an inclined plate type structure and used for shortening the retention time of rainwater in the variable slope type diversion trench. A greenbelt is arranged on the other side of the cut-in notch; one side of the bottom of the variable-slope diversion trench is communicated with one side of the cut-in notch, and the other side of the cut-in notch is communicated with the greenbelt; the shear section of the cut-in notch is in an arc shape, and the longitudinal shear included angle of the cut-in notch along the road is 15-30 degrees. The integrated open kerb effectively solves the problem of low rainwater runoff interception efficiency of the open kerb of the low-influence developed urban road.
本发明涉及一种带导流槽的一体式开口路缘石，属于雨水处理技术领域。包括：“W”型雨水篦、变坡式导流槽以及开口路缘石，所述开口路缘石上设置有贯穿开口路缘石两侧的切入式豁口；所述切入式豁口一侧的道路上设置有变坡式导流槽；变坡式导流槽上覆盖有“W”型雨水篦；所述变坡式导流槽的两面均采用斜板式结构，用于减少雨水在变坡式导流槽内的停留时间；所述切入式豁口另一侧设置有绿地；变坡式导流槽底部一侧与切入式豁口一侧连通，切入式豁口另一侧与绿地连通；所述切入式豁口的切变段为一弧形，沿道路纵向切变夹角为15‑30°。本发明有效解决了低影响开发城市道路开口路缘石雨水径流截留效率低的问题。
