Drainage device for building bridges

Abstract

The invention discloses a draining device for building bridges. The draining device comprises a steel structural rack, a concrete beam, a waterproof layer and an asphalt pavement, wherein the concrete beam is positioned at the upper part of the steel structural rack; the waterproof layer is paved on the upper part of the concrete beam; the asphalt pavement is paved on the upper part of the waterproof layer; a draining groove is formed in the asphalt pavement; a draining groove cover plate covers on the draining groove; a draining pipe is embedded into the asphalt pavement, and a group of water inlet pipe nozzles are externally connected to the position, at the lower part of the draining groove, of the asphalt pavement; an overflow pipe is externally connected to one side of the draining pipe; one end of the draining pipe is connected with a water storage tank; an air compressor is detachably connected with the top of the water storage tank, and a feed pipe is externally connected with the bottom of the water storage tank; an electronic valve is arranged on the draining pipe in a connecting manner. The draining device has excellent waterproof performance, good draining effect and glide prevention property, can be used for collecting water and watering a bridge surface for cooling in hot weather in summer, and is humanized in design.

Description

technical field [0001] The invention relates to the field of drainage devices, in particular to a drainage device for building bridges. Background technique [0002] The bridge is an important traffic building in the city, which meets the needs of driving. There are still deficiencies in the design of the bridge structure currently used. When the road surface is damaged, it becomes difficult to drain rainwater. The water on the bridge surface easily penetrates the asphalt layer and damages the concrete beams inside the bridge. Moreover, the discharged water cannot be used. Now a more suitable drainage method for bridges is needed. structure to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a drainage device for building bridges, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical...
