Roadbed structure for tramcar and construction method thereof
The invention discloses a roadbed structure for a tramcar and a construction method of the roadbed structure, and belongs to the field of urban rail transit engineering.The roadbed structure is characterized in that a surface layer and a base layer of an existing road and a cushion layer with the bearing capacity not meeting the requirement are broken off on a main road, and the cushion layer is excavated and filled with light concrete to serve as a foundation bed bottom layer of the tramcar; the method comprises the following steps of: firstly, pouring a C40 reinforced concrete layer on an existing main road base, then filling 5% cement stabilized graded broken stones on the C40 reinforced concrete layer until the top surface of the original existing road base, then pouring a C40 reinforced concrete supporting layer on the cement stabilized graded broken stone layer, and paving a tramcar track when the strength of the supporting layer reaches 100% of the design strength, so that the technology greatly reduces the damage to the existing main road, reduces the earthwork excavation volume, and reduces the construction cost. And the existing main road cushion layer is used as the tramcar foundation bed bottom layer, so that the construction cost is reduced, the construction period is shortened, the influence on the surrounding environment is reduced, and good popularization and application prospects and social and economic values are achieved.
本发明公开了一种用于有轨电车的路基结构及其施工方法，属于城市轨道交通工程领域，其通过即在主干路上破除既有道路面层和基层和承载力不满足要求的垫层，将垫层挖除换填轻质混凝土作为有轨电车基床底层，然后在其上填筑5％水泥稳定级配碎石至原既有道路基层顶面，接着在水泥稳定级配碎石层上浇筑C40钢筋混凝土支承层，待支承层强度达到设计强度的100％时铺筑有轨电车轨道，该项技术极大地减少了对既有主干路的破坏，减少土方开挖量，且利用既有主干路垫层作为有轨电车基床底层，降低工程造价，缩短工期，减小对周边环境影响，具有良好的推广应用前景和社会经济价值。
