Description

Integrated open curb with diversion trench
Technical Field
The invention relates to a curb, in particular to an integrated open curb with a diversion trench, and belongs to the technical field of rainwater treatment.
Background
In sponge city construction, low influence development urban roads are widely applied, namely, open type curbs are arranged between roads and green belts, and road rainwater runoff is converged into surrounding green lands to be regulated, stored and purified. At present, the methods for developing the opening of the road kerb in low influence in engineering mainly comprise the following steps: (1) the single curb opening, this kind of mode curb opening receives road cross slope, longitudinal gradient, side ditch etc. to influence great to the entrapment rate of road rainfall runoff, and especially when the road longitudinal gradient is greater than the cross slope, the curb opening is lower to road rainfall runoff entrapment rate, can't satisfy the engineering design requirement. (2) Curb opening and road change slope combination owing to set up the road change slope before the curb opening, increased the opening front runoff depth of water, consequently improved the curb opening to road rainwater runoff hold back efficiency, but this kind of mode road construction is loaded down with trivial details to the slope of road change slope is difficult to control, and has driving safety hidden danger. Aiming at the problems existing in the engineering application, the invention provides an integrated open curb device with a diversion trench and a concave-down reinforced water-collecting type rainwater grate, which can realize the efficient interception of rainwater runoff on a road, is convenient for construction and installation and can not cause traffic safety hidden trouble.
At present, the method for developing the road curb opening with low influence has received wide attention, and the published relevant patents are as follows: chinese patent publication CN 108589466A' A curb opening drainage device for intercepting initial rainwater, the patent sets a drainage groove around the periphery of a gutter inlet, the gutter inlet is connected with a curb opening downwards along the longitudinal slope direction of a road, and the curb opening is discharged through the gutter inlet when the rainfall is large, the device has low interception efficiency of the interception groove because the gutter inlet is positioned at the upstream of the opening, the height difference between the gutter inlet and the bottom of the drainage groove is small, and a rainwater grate is easy to loosen, the interception groove also has potential safety hazards of driving, and the construction is inconvenient; CN109837817A 'a curb for sponge city', in which diversion branch pipes are arranged inside the curb and the road surface, and a diversion main pipe is connected with a downcomer, but the diversion main pipe focuses more on drainage; the Chinese patent publication CN111705589A discloses that the hollow permeable curb, the rainwater well in the green belt, the underground rainwater adjusting tank and the pipeline connecting the components are designed in the rainwater collecting system of the hollow permeable curb, the facility structure is complex, the road rainwater runoff interception rate is low, and the daily maintenance and management are not convenient. Chinese patent publication CN105648873A "a cabin holds formula curb" road rainwater is mainly collected through rainwater collection hole, but this curb does not set up and greenbelt drainage channel, and road rainfall runoff surpasss rainwater collection hole easily, leads to urban road rainfall runoff to hold back inefficiency.
