Old bridge floor drainage emergency transformation system and bridge

Abstract

The invention discloses an old bridge floor drainage emergency transformation system and a bridge, and relates to the technical field of municipal bridge engineering. The system comprises a vertical drainage pipe, a longitudinal drainage pipe, a hazardous chemical substance identification sensor and an emergency pipeline, an inlet of the longitudinal drainage pipe is connected with an outlet of the vertical drainage pipe, the hazardous chemical substance identification sensor is arranged at an outlet of the longitudinal drainage pipe and is used for making a hazardous chemical substance alarm when recognizing that hazardous chemical substances exists in the passing rainwater, and the emergency pipeline comprises an emergency pipeline body and a first control switch; when the first control switch receives the hazardous chemical substance alarm, the first control switch is in an open state, otherwise, the first control switch is in a closed state, and a non-emergency pipeline comprises a non-emergency pipeline body and a second control switch; and when the second control switch receives the hazardous chemical substance alarm, the second control switch is in a closed state, and otherwise the second control switch is in an open state. According to the old bridge floor drainage emergency transformation system and the bridge, the rainwater containing pollutants and the rainwater containing the hazardous chemical substance can be separated, and the rainwater containing the pollutants or hazardous chemical substances can be prevented from directly flowing into a river body.

Description

technical field [0001] The invention relates to the technical field of municipal bridge engineering, in particular to an emergency reconstruction system for drainage of old bridge decks and a bridge. Background technique [0002] In recent years, with the construction and development of society, on the basis of ensuring the quality of engineering construction, more and more attention has been paid to the protection of the ecological environment. Therefore, the drainage of bridges across important and sensitive urban lakes with high water quality requirements is also becoming more and more important. Pay attention to. [0003] According to the data, during the operation of highways or urban bridges, the pollutants of the initial rainwater runoff on the road surface are complex, and the bridge deck runoff (especially the initial runoff) generated by rainfall contains a certain amount of pollutants such as suspended particles, organic matter, nutrients and heavy metals. , if i...

Problems solved by technology

At the same time, once accidents happen to vehicles transporting dangerous chemicals in sensitive water areas and the dangerous goods are directly released into the water body, it will also cause great harm to the water environment and even damage the water ecological environment.

[0004] On the other hand, judging from the current situation of drainage of bridges across rivers in domestic cities, most of the old bridges have bridge deck drainage facilities that are missing or not smooth, and bridge deck drainage will directly flow into the river body through bridge decks or vertical drainage holes. , can easily affect the receiving water body
