A rapid rainwater collection system for urban elevated roads and its construction method

Abstract

The invention discloses an urban elevated road rainwater fast collecting system and a construction method thereof. The urban elevated road rainwater fast collecting system comprises a first water storage tank, a second water storage tank, a quick water passing assembly and a drainage pipe fitting; the quick water passing assembly is located on a guardrail, a drainage cavity is formed in the guardrail, and a limiting groove is formed in the side face of the guardrail; the first water storage tank is located in a bridge girder and communicates with the quick water passing assembly; and the second water storage tank is located at the position between two bridge piers, and the first water storage tank is connected with the second water storage tank through the drainage pipe fitting along the bridge piers. The construction methods comprises the steps of surveying and setting out of an elevated bridge girder, constructing of the quick water passing assembly, constructing of the first water storage tank, constructing of the drainage pipe fitting, constructing of the second water storage tank and trial running of the collecting system. According to the urban elevated road rainwater fast collecting system and the construction method thereof, the construction method is simple in step, construction and installation can be conducted on an existing elevated bridge girder, and rainwater accumulation of the elevated bridge girder due to heavy rain and seriously affecting on running safety are effectively prevented.

Description

technical field [0001] The invention relates to a rainwater rapid collection system for urban elevated roads and a construction method thereof. Background technique [0002] Against the backdrop of the country's rapid economic growth, China's urbanization rate is constantly accelerating, and the road network within cities and between cities is constantly being densified and widened. In order to solve the huge traffic pressure in urban areas, the main roads of many cities are already lined with elevated roads. [0003] The width of these elevated roads can reach tens of meters. Such a large area of ​​viaducted roads can collect considerable rainwater. However, at present, the rainwater on the viaduct road surface in the city is directly discharged into the urban rainwater drainage system, which not only wastes water resources, but also increases the pressure of the downstream rainwater drainage system. And the use effect of the rainwater collection system in the prior art i...

Problems solved by technology

However, at present, the rainwater on the viaduct road in the city is directly discharged into the urban rainwater drainage system, which not only wastes water resources, but also increases the pressure of the downstream rainwater drainage system

Moreover, the rainwater collection system in the prior art has a poor use effect, and it cannot quickly discharge the rainwater on the viaduct deck in the rainstorm season, which will easily cause rainwater accumulation on the viaduct deck, and there is a certain hidden danger to driving safety.
