Water-accumulation-prevented bridge floor

Abstract

The invention discloses a water-accumulation-prevented bridge floor. The water-accumulation-prevented bridge floor comprises an arc-shaped bridge body supporting foundation and an arc-shaped bridge floor, wherein the arc-shaped bridge floor is a concrete bridge floor or asphalt bridge floor, a plurality of step grooves are formed in the upper surface of the arc-shaped bridge floor in a spaced manner, the step grooves are formed along the width direction of the arc-shaped bridge floor, two water guiding grooves are formed in the upper part of the arc-shaped bridge body supporting foundation, the water guiding grooves are respectively formed in the two sides of the arc-shaped bridge floor, a cover plate is arranged at the upper parts of the step grooves and respectively comprises an upper-part rubber plate and a bottom steel plate arranged underneath the upper-part rubber plate, and draining through holes which point to the bottoms of the step grooves are respectively formed in the cover plate. By the manner, according to the water-accumulation-prevented bridge floor disclosed by the invention, rainwater on the bridge floor is segmented, respectively passes through the cover plate and then enters the step grooves, so that water flow is scattered, and water accumulation is avoided; due to the upper-part rubber plate, the friction force to tires is increased, vehicle skidding is reduced, and the braking performance can be improved.

Description

technical field [0001] The invention relates to the field of municipal bridge engineering, in particular to a waterlogging-proof bridge deck. Background technique [0002] According to the structure of the bridge deck, bridges are mainly divided into straight-line bridges and arc-surface arch bridges. Straight-line bridges are relatively flat and basically have no slope, which is convenient for pedestrians and vehicles to pass. The slope is not conducive to the passage of pedestrians and vehicles. [0003] In order to meet the needs of traffic, some overpasses and river-crossing bridges must be designed with arc-shaped bridge decks. The impact on normal traffic is not great, but the road is slippery in rainy days, and arc-shaped bridge decks are more slippery under the action of accumulated water or water flow. , affect the normal driving and braking of the vehicle, and easily cause accidents. Contents of the invention [0004] The main technical problem to be solved by ...
