Concentrated rainwater drainage structure for bridge pier type road construction

Abstract

The invention discloses a concentrated rainwater drainage structure for bridge pier type road construction. The concentrated rainwater drainage structure comprises a bottom supporting bridge plate, a concrete layer, an external drain pipe and a preventive stone pier edge, wherein a connective supporting bridge plate is arranged on the upper end of the bottom supporting bridge plate, a reinforced supporting bridge plate is arranged on the upper layer of the connective supporting bridge plate, bridge plate-bridge pier supporting pillars are arranged on the lower end of the bottom supporting bridge plate at equal intervals, side vertical drain pipe storage ports are reserved at the side positions of the concrete layer and the road upper surface layer, and the preventive stone pier edge is tightly arranged on the outer sides of the concrete layer and the road upper surface layer. The concentrated rainwater drainage structure for bridge pier type road construction is designed by combining the self structure of the existing city overhead road, the road surface layer is divided through an isolating fence in considering the drainage structure form of the road, the whole drain pipeline is arranged in the concrete layer, a heat insulating layer is externally arranged for protecting the water pipe and preventing the water pipe from being frozen in winter, and the service life of the whole drainage structure is prolonged.

Description

technical field [0001] The invention relates to the technical field of road and bridge structures, in particular to a pier-type rainwater centralized discharge structure for road construction. Background technique [0002] With the development of the times, urban construction is getting faster and faster, especially the construction and development of urban roads. In order to meet more vehicles, a large number of urban elevated roads have been built. [0003] The road is an elevated road, that is, a viaduct, also known as a flyover bridge, a bridge that rests on a series of narrow reinforced concrete or masonry arches, with towers or pillars of high support, and spans valleys, rivers, roads, or other Bridges with low obstacles. [0004] At the same time as the road construction, it is necessary to have an auxiliary structure for road drainage, so that rainwater accumulation will no longer occur on the elevated road in rainy days. A perfect drainage structure can make road d...
