Abstract

The invention discloses a vertical rainwater zoning drainage system which comprises a concave green area, a low-zone rainwater disposal facility and a high-zone rainwater disposal facility, wherein the low-zone rainwater disposal facility comprises a municipal rainwater inspection well, a road gully on the side of a road, and a sheetflood gully in the concave green area; the high-zone rainwater disposal facility comprises an overflow gully in the concave green area, a water collecting basin and an emergency rainwater discharge pump set; the overflow gully is connected with the water collecting basin; the water collecting basin is connected with the emergency rainwater discharge pump set; a delivery outlet of the emergency rainwater discharge pump set is communicated with an urban flood drainage channel or a ravine or a depression; the municipal rainwater inspection well is communicated with the sheetflood gully; the road gully is connected with an overflow communicating pipe; an outlet of the overflow communicating pipe is communicated with the concave green area; the overflow gully is designed in the specification that P is greater than set P; and the sheetflood gully is designed in the specification that P is less than or equal to set P. The system nips in the bud, can effectively prevent and treat a waterlogging disaster generated by rainstorm, can ensure personal and property safety, and changes passive salvation after the disaster into positive prevention and treatment before the disaster.

Description

technical field [0001] The invention belongs to the technical field of rainstorm and waterlogging disaster prevention and control in low-lying areas of cities and towns, in particular to a rainwater vertical partition drainage system. Background technique [0002] In the past two years, the climate has been abnormal, with frequent rainstorms and severe waterlogging in low-lying urban areas such as underground buildings, sunken squares, and sunken sections of road overpasses, which can cause pedestrians to be blocked and traffic to be paralyzed, and serious casualties and major property losses . In order to rescue the waterlogging disaster, it consumes a lot of manpower and financial resources. With regard to its reason, mainly contain following deficiency and insufficiency: [0003] 1. The rainwater part in the outdoor drainage design specification is more focused on conventional rainfall (P≤P within the design return period range) 设 ) exclusion, for heavy rain (P≥P 设 gr...
