Embodiment Construction
[0015] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0016] like figure 1 , figure 2 and image 3 As shown, the present invention includes at least one rainwater collection and lifting device 1 that collects rainwater and withstands vehicle rolling and squeezes rainwater. The bottom of the device 1 is connected to the drainage mechanism 2, and the mouth of the drainage mechanism 2 is connected to the water delivery pipe 3. A one-way Drain valve 4.
[0017] figure 1 For the low-lying road rainwater collection and lifting system composed of three rainwater collection and lifting devices on the slope, those skilled in the art can set the number of rainwater collection and lifting devices according to the height of the slope, so as to realize the lifting of rainwater in low-lying places to high places until the low-lying rainwater is discharged. standing water.

The invention relates to a rainwater collecting and lifting system for low-lying roads. The rainwater collecting and lifting system comprises at least one rainwater collecting and lifting device (1) which is used for collecting rainwater and bearing the rolling of a vehicle to implement extrusion on the rainwater, wherein the bottom part of the rainwater collecting and lifting device (1) is connected with a water discharging mechanism (2); a pipe opening of the water discharging mechanism (2) is connected with a water delivery pipe (3); and the connecting position between the rainwater collecting and lifting device (1) and the water discharging mechanism (2) and the connecting position between the water discharging mechanism (2) and the water delivery pipe (3) are respectively provided with a one-way water discharging film flap (4). The rainwater collecting and lifting system has the following advantages that the runoff on the low-lying road can be accumulated, the rainwater accumulation at the urban low-lying region can be reduced, simultaneously the energy generated by vehicle rolling on a speed reducing zone can be utilized to transfer / lift the accumulated water on the urban roads, and the problem of waterlogging formed by rainwater accumulation at the urban low-lying region during rainfall can be relieved, even solved.
Description
technical field [0001] The invention belongs to the technical field of urban rainwater control, and in particular relates to a low-lying road rainwater collection and lifting system. Background technique [0002] At present, with the continuous expansion of the scale of cities in our country, the types of land use have undergone tremendous changes, and a large number of impermeable surfaces have appeared, making the runoff formed by urban rainfall much larger than in the past. Due to the lack of planning and low design standards in the design of urban drainage pipelines, the existing drainage systems in many cities cannot meet the requirements of rapid drainage. With the frequent occurrence of extreme weather in recent years, the problem of urban waterlogging has become increasingly serious . Take the heavy rain in Beijing in 2012 as an example. On July 21, Beijing experienced the largest precipitation with complete meteorological records since 1951. According to statistics...
