Embodiment Construction

[0023] The present invention will be further described below in conjunction with drawings and embodiments.

[0024] Such as figure 1 , figure 2 and image 3 As shown, the urban arterial road cross-section optimization system described in the present invention includes successively a median divider, a motor vehicle lane, a machine-non-motor divider, a non-motor vehicle lane and a sidewalk; the system also includes a The sunken green belt 5 is set in the rain garden 15, the first grass planting shallow ditch 17, the gravel pool 12, and the sandy rainwater outlet 13 in the machine-non-divided zone; type side stone 2, a second shallow ditch 1 for planting grass is provided in the median strip near the first vertical side stone 2, to prevent the rainwater from washing the soil in the median strip to the motorway during heavy rain; One side of the motorway is provided with an intermittent gap vertical side stone 3, and the gap of the intermittent gap vertical side stone 3 ...

Abstract

The invention discloses an optimize system for urban trunk road cross-sections, which comprises a medial strip, a motorway, a non-motorized strip, a non-motorized vehicle lane, a concave green belt and a sidewalk in sequence, wherein a rainwater garden, a first grass planting shallow trench, a gravel pool and a sand setting rainwater inlet are arranged in the non-motorized strip; first vertical curbstones are respectively arranged on two sides of the medial strip; a second grass planting shallow trench is formed in the medial strip close to the vertical curbstones; an intermittent gap vertical curbstone is arranged on one side, close to the motorway, of the non-motorized strip; a first flat curbstone is arranged at a gap of the intermittent gap vertical curbstone to form a rainwater inlet; a punching, seeping and discharging pipe and a first overflow port are arranged in the rainwater garden; a rainwater connecting pipe is arranged below the non-motorized vehicle lane and is in mutual communication with a municipal rainwater pipeline; the rainwater treatment method comprises the following steps: runoff rainwater treatment in the motorway and runoff rainwater treatment in the sidewalk and the non-motorized vehicle lane. The runoff rainwater treatment in the motorway comprises the following steps: precipitating, filtering, concentrating and discharging.

Description

technical field [0001] The invention relates to the technical field of road cross-section design and rainwater treatment, in particular to an urban arterial road cross-section optimization system and a rainwater treatment method. Background technique [0002] The increase of the ground hardening rate in my country's cities has blocked the supplement of rainwater to groundwater, and the rainwater on the road and surrounding areas has flowed away from the urban rainwater and sewage pipe network in vain. The treatment plant and the water environment are overwhelmed, and the pressure on flood control and internal waterlogging is increasing, which affects the urban water circulation system. Therefore, it is very necessary to increase the infiltration effect of rainwater in the green belt and realize the comprehensive utilization of rainwater. [0003] In the cross-sectional design of urban roads, usually the central divider of the road accounts for a large proportion of the green...
