Expressway bridge drainage structure

Abstract

The invention discloses an expressway bridge drainage structure, and belongs to the technical field of expressway bridge drainage. The drainage structure includes drainage ditches on an expressway bridge pavement, draining holes at the bottoms of the drainage ditches, anti-blocking assemblies at the internals of the draining holes, drainage ports at the bottoms of an expressway bridge and fixing concrete blocks on the two sides of the expressway bridge; the drainage ditches are located on the two sides of the expressway bridge pavement; multiple draining holes are arranged in the length directions at the bottoms of the drainage ditches; the bottoms of the draining holes pass through the expressway bridge pavement; the anti-blocking assemblies are arranged corresponding to the number of thedraining holes; the internals of the fixing concrete blocks are provided with driving assemblies for driving the anti-blocking assemblies to work; and the number of the driving assemblies is consistent with the number of the draining holes. The draining pressure of the main body drainage ditches can be shared by the multiple drainage ports, so that high draining efficiency can be achieved; and the internal of each drainage port is provided with the anti-blocking assembly to perform the cleaning of the drainage ports, so that good anti-blocking effects can be realized, and follow-up overhauling can be reduced.

Description

technical field [0001] The invention belongs to the technical field of highway bridge drainage, and in particular relates to a highway bridge drainage structure. Background technique [0002] With the rapid development of public transportation, a large number of bridges have been built due to their characteristics of crossing rivers and shortening road mileage, especially for bridges used on expressways. In order to improve the service life of bridges, construction personnel have set up drainage structures on bridges . At present, the drainage structure on the bridge is drained through simple pipes, which can play a good drainage effect for small water flow, but the drainage time is long; when faced with heavy rain, the simple pipes of the bridge cannot meet its needs. The need for use usually leads to water accumulation on the bridge, which brings hidden dangers to drivers, seriously affects the service life of the bridge pavement, and increases the maintenance cost in the...

At present, the drainage structure on the bridge is drained through simple pipes, which can play a good drainage effect for small water flow, but the drainage time is long; when faced with heavy rain, the simple pipes of the bridge cannot meet its needs. Due to the need for use, it usually leads to water accumulation on the bridge, which brings hidden dangers to drivers, and also seriously affects the service life of the bridge pavement, increasing the maintenance cost in the later period.
