A floating bridge deck runoff collection device

Abstract

The invention belongs to the field of highway bridges across sensitive water bodies, and specifically discloses a floating bridge deck runoff collection device. The device includes a collection unit, a monitoring unit and a control unit, wherein: the floating collection box of the collection unit is set on the outside of the bridge pier and floats on the water surface for collecting bridge deck runoff; the water inlet of the multi-way valve and the bridge deck runoff collection pipe The water outlet of the multi-way valve is connected to the water delivery pipe and the straight discharge pipe respectively, and at the same time the water delivery pipe is connected to the water inlet hole on the floating collection tank, and the straight discharge pipe directly leads to the water body; the monitoring unit is used to monitor the bridge deck runoff and the collection unit for monitoring; the control unit is used to receive the signal of the monitoring unit and control the multi-way valve according to it, so as to realize the collection or discharge of bridge deck runoff. The invention can make full use of a large amount of non-navigable space between the bridge deck and the water surface, is not limited by the bridge head site and hardly increases the bearing capacity of the bridge, improves the space utilization rate and is more beautiful.

Description

technical field [0001] The invention belongs to the field of highway bridges across sensitive water bodies, and more specifically relates to a floating bridge deck runoff collection device. Background technique [0002] With the continuous development of our country's economy and society, while the number of highway bridges across sensitive water bodies in our country is increasing rapidly, the amount of hazardous chemicals transported by road is also increasing. Pollution of water-sensitive targets such as drinking water sources near expressways caused by accidents of hazardous chemical transport vehicles has increasingly become a major environmental risk during expressway operation. At the same time, due to daily operation, the initial rainwater of highway bridge deck runoff will contain more pollutants such as solid suspended solids, COD, ammonia nitrogen and even heavy metals, and if it is directly discharged into sensitive water, it will pollute sensitive water.

Problems solved by technology

However, there are large areas of rivers and river beaches under the bridge, and generally there is not much open space at the bridge head for device construction.

When the bridge spans a large water area, the volume of the bridge deck runoff collection device installed at the bridge head is often insufficient; and the installation of fixed bridge deck runoff collection devices by piling under the bridge deck not only brings additional load to the pier, but also increases In addition, it is difficult to implement bridge deck runoff collection devices on existing bridges, especially bridges in water sources and scenic spots.
