Combined pool body for runoff of highway bridge floor

Abstract

The utility model provides a combined pool body for runoff of a highway bridge floor. Belongs to the technical field of traffic infrastructures. According to the technical key points, the device comprises a pool body, a plurality of straight walls are fixedly connected into the pool body at intervals in the runoff direction, the straight walls are matched to divide the pool body into a plurality of collection pools and an accident pool, and the collection pools and the accident pool are of closed pool body structures; an accident pool electric valve is arranged at the top of the straight wall between the accident pool and the adjacent collecting pool, and a collecting pool electric valve is arranged at the lower part of the straight wall between the two adjacent collecting pools; according to the utility model, under the condition that the effective volumes of the existing collecting tank and the accident tank are not changed, the volume of the hazardous chemical liquid is greatly increased, and the risk that the hazardous chemical liquid is excessively discharged into the external environment is avoided; and the dangerous chemical accident dealing strength of the expressway is improved.
