A kind of steel fiber concrete pavement and its construction technology at the intersection of tram and road

Abstract

The invention discloses a steel fiber concrete pavement of a tram and urban road intersection and a construction technology thereof. The steel fiber concrete pavement of the tram and urban road intersection mainly comprises a roadbed, a pair of steel rails, steel fiber concrete structures and an asphalt structure, wherein the steel rails are fixed at the upper end of the roadbed and the steel fiber concrete structures are arranged at the lateral edges of the steel rails. The construction technology mainly comprises the following steps: paving the steel rails; constructing the pavement of the asphalt structure; reversely digging the asphalt pavement at the overlapped joint of the steel rails; drilling and fixing rebar; binding the rebar meshes; mixing the steel fiber concrete; pouring the steel fiber concrete; maintaining the steel fiber concrete; treating the reserved gaps; opening the traffic. Compared with the prior art, the invention has the advantages that the steel fiber concretestructure is additionally arranged, the service life is long and the problem of insufficient strength of the asphalt pavement is solved due to the structure design of the steel fiber concrete and rebar, the pavement can bear the repeated load of the heavy-weight transportation and the probability of pavement damage can be greatly reduced.

Description

technical field [0001] The invention relates to pavement structure design and its construction technology, in particular to a steel fiber concrete pavement at the level intersection between trams and roads and its construction technology. Background technique [0002] Modern trams have the advantages of energy saving and environmental protection, small investment, moderate passenger capacity, comfortable riding, and low maintenance costs in the later period. Therefore, many small and medium-sized cities at home and abroad are regarded as public transportation with priority for development. In the planning, design, construction and operation of trams, in order to reduce investment, a large part of the routes form collinear sections with the existing municipal roads. Especially at level intersections, a mixed right of way for trams, cars, pedestrians, and non-motor vehicles is formed. [0003] At present, in order to improve the uniform appearance of the pavement at road inte...
