Anti-blocking highway bridge direct drainage system drainage outlet

Abstract

The invention discloses an anti-blocking highway bridge direct drainage system drainage outlet, comprising a drainage opening. Filter plates with filter holes are arranged along the circumference of the drainage opening, the extensions of the filter plates are of an upward structure, a drainage pipe is arranged in the drainage opening, the drainage pipe is covered with a drainage pipe cover, the inner edges of the filter plates are pressed and fixed between the drainage pipe cover and the drainage opening by the drainage pipe cover, grooves are formed in the periphery of the drainage pipe, thebottom of the drainage pipe communicates with a drain pipe, and the drain pipe directly communicates with a water area. According to the invention, the filter plates with the filter holes are arranged along the circumference of the drainage opening of the direct drainage system drainage outlet, which can effectively prevent the pollution of floating objects to the drained water of the direct drainage system, and convenient to install and arrange by setting a specific fixing mode according to the structural characteristics of the drainage pipe cover and the drainage opening.

Description

technical field [0001] The invention belongs to the technical field of bridge drainage, in particular to a drainage outlet of an anti-blocking highway bridge straight drainage system. Background technique [0002] The drainage of highway bridges usually adopts cast iron or PVC drainpipes, which are installed at the lower side of the bridge deck cross slope. The bridge deck drainage is collected through the blind ditch and then discharged directly under the bridge or collected through longitudinal pipes and then led to the ground at the pier and abutment. in the drainage system. [0003] For bridges crossing sensitive waters, due to the requirements of the environmental protection department, bridge deck sewage shall not be directly discharged into sensitive water bodies. Usually, bridge deck runoff collection systems are installed. Longitudinal collection pipes are installed along the bridge to collect the bridge deck drainage. The environmental protection department will h...
