Special roadbed structure above subway and construction method thereof
The invention discloses a special subgrade structure above a metro and a construction method thereof in the technical field of subgrade structures of metro sections, and the special subgrade structure comprises a light foam concrete subgrade laid between a pavement and a subgrade above a metro tunnel, and a pavement structure layer is laid on the top of the light foam concrete subgrade. Concrete retaining walls are arranged on the two sides of the light foam concrete roadbed, filling protection slopes are arranged on the outer sides of the concrete retaining walls, piles are arranged at the bottoms of the light foam concrete roadbed and the filling protection slopes on the two sides respectively, the weight of the embankment structure is reduced through foam concrete, and the phenomenon of foundation settlement under the condition that the load is too large is avoided; the structure is high in stability, the light foam concrete roadbed and foundations of different geologies are stably connected through adjustment and selection of pile types and embedding forms and reinforced application of the frame pile beams, differential settlement of the roadbed can be effectively reduced, and therefore operation safety of a subway is guaranteed.
本发明公开了地铁地段路基结构技术领域的一种地铁上方特殊路基结构及其施工方法，包括铺设于路面与地铁隧道上方路基之间的轻质泡沫混凝土路基，轻质泡沫混凝土路基的顶部铺设有路面结构层，轻质泡沫混凝土路基的两侧设置有混凝土挡墙，混凝土挡墙的外侧设置有填土护坡，轻质泡沫混凝土路基以及两侧填土护坡的底部均分别设置有桩，采用泡沫混凝土使得路堤结构重量减小，以避免在荷载过大的情况下出现地基沉降现象，更具稳定性，通过桩类型以及嵌埋形式的调整选择以及框架桩梁的强化应用，使得轻质泡沫混凝土路基与不同地质的地基之间的稳固连结，从而可以有效减少路基的差异沉降，从而保证地铁的运行安全。
