Light base system and construction method for bridge deck sidewalk

Abstract

The invention discloses a light base system for a bridge floor sidewalk and a construction method thereof and belongs to the technical field of road and bridge construction. The light base system comprises an inner side steel base and an outer side steel base. Supporting steel plates are arranged on the surface of the inner side steel base and the surface of the outer side steel base correspondingly. A sidewalk plate is supported on the upper edge face of the supporting steel plates. A small water drainage pipe is arranged on the upper edge of the inner side of the inner side steel base. A large water drainage pipe is arranged on the lower edge of the inner side of the inner side steel base. According to the light base system, a light steel base is adopted, the weight of the base is reduced greatly, thus the use amount of materials of a girder is reduced, a certain economical effect is achieved, by additionally arranging the small water drainage pipe, water accumulating on the top of the sidewalk plate can be drained in time, the situation that the accumulated water permeates into the bridge floor under the plate and cannot be drained is avoided, then durability of the bridge is improved, during the construction period, the steel base does not need to be maintained, the construction period is shortened obviously, all the components can be directly purchased or constructed on site, site construction is easy, the cost is low, and the light base system has a good effect and is worth of being widely used.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a light foundation system for bridge deck sidewalks and a construction method thereof. Background technique [0002] The sidewalk on the urban bridge deck is generally higher than the inner motorway, and the sidewalk slab is supported on the inner curb and the outer guardrail base, and the pipeline can run under the slab. Curb stones and guardrail bases generally adopt concrete structures, which are large in size and heavy in weight, which increases the dead load of the bridge in the second phase. In recent years, there have been many accidents of vehicles falling into rivers in China, and the anti-collision ability of urban bridges has also become the focus of attention. Therefore, the new regulations have adjusted the size requirements of the base and the sidewalk, resulting in a further increase in the weight of the curb and the base of the guardrail. In ...

Problems solved by technology

Therefore, the new regulations have adjusted the size requirements of the base and the sidewalk, resulting in a further increase in the weight of the curb and the base of the guardrail. In addition, the sidewalk board is located inside the curb and the base of the guardrail, and the rainwater on the top of the board will flow along the road. The curb seeps into the bridge deck, but cannot drain out, thus affecting the durability of the bridge
