Construction method for special roadbed in plateau mountain area
The invention discloses a construction method for a special roadbed in a plateau mountain area. The construction method comprises the steps of filling section karst roadbed treatment construction, excavation section karst roadbed treatment construction and karst cave treatment quality control construction. Wherein a reinforced concrete cover plate spanning type structure is adopted in the filling section karst roadbed treatment construction, sundries in a karst cave are removed firstly, then rubbles are adopted for backfilling and top sealing, then a reinforced concrete cover plate is adopted for spanning the karst cave, the periphery of the karst cave opening is covered by 50-100 cm, and the filling section karst roadbed is constructed. And it is ensured that the cover plate and the original rock are combined into a whole to form an effective composite foundation after being poured. The special roadbed construction technology is optimized, the construction cost is reduced, and the problem of differential settlement of the roadbed in the later period is solved.
本发明公开了一种高原山区特殊路基的施工方法，包括填方段岩溶路基处置施工、挖方段岩溶路基处置施工和溶洞处理质量控制施工；其中，填方段岩溶路基处置施工采用钢筋混凝土盖板跨越式结构，先对溶洞内杂物进行清除，再采取片石回填并封顶，然后采用钢筋混凝土盖板跨越溶洞，搭盖溶洞洞口四周50～100cm，确保盖板浇筑后和原有岩石结合成一整体形成一个有效的复合地基。本发明优化特殊路基施工工艺，降低了施工成本，减少后期因路基不均匀沉降问题。
