A drainage system for bridge construction

Abstract

The invention discloses a drainage system for bridge construction. The drainage system for bridge construction comprises a bridge supporting base, a bridge board, a drainage device, a connecting channel, a hanging bracket, a first screw, an upper fixing base, a second screw, a lower supporting base, a lower backing plate, longitudinal drainage pipes, an upper backing plate, a first connecting sleeve, a first elastic connecting pipe, a fixed pipe, a second elastic connecting pipe, a second connecting sleeve, a waterproof layer, a third screw, a flange and a seal gasket. The drainage system for bridge construction is reasonable and simple in structure, the drainage device can make water on the bridge floor flow into the longitudinal drainage pipes, a filtering sleeve and a filtering cover in the drainage device can filter out rubbish in the water, and a drainage pipeline is prevented from being blocked by the rubbish; in addition, a drainage hose is arranged and located in a protective pipeline, and drainage of the drainage hose is not affected when the protective pipeline is broken; the first elastic connecting pipe and the second elastic connecting pipe can effectively ensure connection stability between the longitudinal drainage pipes.

Description

Technical field: [0001] The invention relates to the field of bridge engineering, in particular to a drainage system for bridge construction. Background technique: [0002] Generally, bridges are equipped with drainage systems. For long bridges spanning highways, railways, and navigable rivers, the bridge deck drainage is usually divided into vertical water collection and then discharged into the ground drainage facilities through the vertical drainage pipes installed at the bridge piers; That is, the drainage system commonly used in the prior art is composed of a drainpipe arranged on the bridge deck, a longitudinal water collecting pipe under the bridge deck, and a vertical drainpipe arranged at the transition pier or abutment of the bridge. The vertical water collection pipe is connected; one end of the vertical water collection pipe is connected with the vertical drainage pipe; the vertical drainage pipe is connected to the ground drainage facility. This kind of drainag...
