Embodiment Construction

[0021] Attached below Figure 1-3 The present invention will be described in detail.

[0022] Such as Figure 1-3 As shown, an integrated open curb stone with a diversion groove in this embodiment includes: a "W" type rainwater grate 1, a variable slope diversion groove 3 and an open curb stone 6, and the open curb stone 6 is provided with The cut-in gap 2 running through both sides of the curb stone 6 of the opening. The road on one side of the cut-in gap 2 is provided with a variable-slope diversion groove 3, and the variable-slope diversion groove 3 is integrated with the opening curb 6. The variable-slope diversion groove 3 is covered with a "W" type rainwater grate 1, and the rainwater on the road can enter in the variable-slope type diversion groove 3 along the road transverse slope and longitudinal slope. Both sides of the variable-slope diversion groove 3 adopt a sloping plate structure, which is used to reduce the residence time of rainwater in the variable-slope d...

Abstract

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.

Description

technical field [0001] The invention relates to a curb stone, in particular to an integrated open curb stone with a diversion groove, and belongs to the technical field of rainwater treatment. Background technique [0002] In the construction of sponge cities, low-impact development of urban roads has been widely used, that is, open curbs are set between roads and green belts, and rainwater runoff from roads is transferred to surrounding green spaces for storage and purification. At present, the methods of low-impact development road curb openings in the project mainly include the following types: (1) Single curb openings, the interception rate of road rainwater runoff by curb openings in this way is affected by road transverse slopes, longitudinal slopes, side ditches, etc. The impact is greater, especially when the longitudinal slope of the road is greater than the transverse slope, the curb stone opening has a low interception rate of road rainwater runoff, which cannot m...
