Construction method for reinforcing confined space high fill roadbed slope foam concrete
The invention discloses a construction method for reinforcing confined space high fill roadbed slope foam concrete. The construction method includes the steps that a concrete pavement of a to-be-reinforced part is broken, earth fill without slope protection measures at the upper part of a retaining wall is dug out through an excavator, high fill severe in water and soil loss is excavated in layers, a five-to-seven-stage cut slope excavation platform is arranged on a roadbed with a reserved pavement, Larsen steel plate piles are inserted between the cut slope excavation platform and the reserved pavement, a formwork on the outer side of the foam concrete is a disassembly-free formwork, a foam concrete roadbed is poured, and finally a concrete pavement is poured. By means of the constructionmethod, the problem that due to the water and soil loss of a confined space high fill roadbed slope, the roadbed retaining wall settles and horizontally moves to a great degree and vehicles cannot run is solved.
本发明公开了受限空间高填方路基边坡泡沫混凝土加固的施工方法，该施工方法包括破除准备加固部分的混凝土路面，用挖掘机挖去挡土墙上部无做护坡措施的填土，将受水土流失严重的高填方分层开挖，靠近保留路面的路基设置五至七级的放坡开挖平台，该放坡开挖平台与保留路面之间插打拉森钢板桩，泡沫混凝土外侧的支模为免拆模板，浇筑泡沫混凝土路基，最后浇筑混凝土路面，通过本发明的施工方法解决了受限空间高填方路基边坡水土流失，导致路基挡土墙出现很大程度的沉降和水平位移，车辆无法行驶的难题。
