Tramcar viaduct surface greening pavement structure

Abstract

The tramcar viaduct surface greening pavement structure which comprises a bridge body, a reinforced concrete rail bearing table, an EPS foam plate, tramcar rails, lower-layer geotechnical cloth, a ceramsite filler, upper-layer geotechnical cloth, planting soil and turf, and the bridge body comprises a reinforced concrete box girder, two bridge flange plates, a strong current cable channel and a weak current cable channel; the four reinforced concrete rail bearing tables are connected through the reinforced concrete box girder; a plurality of foam board mounting grooves are formed above the reinforced concrete box girder; waterproof and mortar sloping layers are laid in the foam board mounting grooves, and EPS foam boards fill in the foam board mounting grooves; the lower-layer geotechnicalcloth is laid on the EPS foam boards, a ceramsite layer is laid on the lower-layer geotechnical cloth, the upper-layer geotechnical cloth is laid on the ceramsite layer, planting soil is laid on theupper-layer geotechnical cloth, and turf is planted on the planting soil. The civil engineering transformation cost of an existing bridge body structure is not increased, the safety risk of the bridgeis not increased, and the attractiveness degree of an original exposed bridge floor is improved.

Description

technical field [0001] The invention belongs to the field of trams, and more specifically relates to a greening pavement structure of a tram elevated bridge deck. Background technique [0002] At present, domestic modern trams are becoming more and more popular, and tram projects in various places are developing rapidly. Compared with the subway, modern trams have obvious characteristics of light weight, ground-based, scenic spots, etc., and there are many cases where they are used as tourist routes in various places. However, due to the different construction environments of trams in various places, they are basically located in cities, and the lines often cross roads, railways, rivers, etc., so the construction of elevated sections of trams has become indispensable in the construction of modern trams part of the [0003] Since modern trams in cities mostly use ballastless ballast beds, the tracks are anchored on reinforced concrete rail platforms. When two lines are set,...

Problems solved by technology

[0005] When this kind of viaduct deck is greened and paved, the full filling of planting soil will greatly increase the load on the bridge body. In order to ensure the overall safety, the civil construction cost of the bridge will also increase accordingly; in order to reduce investment, some cities tile in trenches The fake turf is sometimes taken up by the train and rolled into the wheel rail, which greatly affects the safety of the tram

Different from the ground section of the tram, which can be filled with planting soil in the above-mentioned trenches, the elevated section has a large amount of filled earthwork, and the load of the soil after absorbing water in rainy days is relatively large, resulting in an increase in the civil construction cost of the bridge itself; while in the trench Setting fake turf in the groove is not only easy to be drawn into the wheel rail by the tram, which increases the risk of operation safety, but also has a much less beautiful appearance than the flat turf on the ground.
