Roadbed construction method for preventing uneven settlement of spliced road
The invention discloses a roadbed construction method for preventing uneven settlement of a spliced road, which comprises the steps of roadbed excavation, construction of a drainage system in a roadbed construction period, step treatment, water seepage treatment of an old roadbed, reinforcement construction of a hydraulic dynamic compactor, reinforcement construction of a heavy road roller and settlement deformation observation. A reverse slope is arranged to ensure the compactness of the old roadbed, slope slippage is effectively avoided, and good drainage engineering measures and temporary drainage facilities near a construction site are established in roadbed construction to keep the roadbed in a dry, firm and stable state frequently. A layer of geocell is respectively laid on the bottom surface of the roadbed, the bottom surface of the embankment and the steps in the middle of the roadbed and the embankment, so that the roadbed has higher lateral limitation, skid resistance and deformation resistance, the bearing capacity and the load dispersing effect of the roadbed are effectively enhanced, the junction of the new roadbed and the old roadbed and the new roadbed are reinforced by adopting two modes of dynamic compaction and rolling compaction, and the construction efficiency is improved. And the stability of the roadbed is effectively enhanced.
本发明公开了防止拼接道路不均匀沉降路基施工工法,所述方法包括路基开挖、路基施工期排水系统的搭建、台阶的处理、老路基渗水处理、液压强夯机补强施工、重型压路机补强施工和沉降变形观测,本方法新老路基交界处采用台阶开挖,设置反向坡确保老路基的压实度,有效避免坡面滑移,路基施工中建立了良好的排水工程措施以及施工场地附近的临时排水设施,以保持路基能经常处于干燥、坚固和稳定状态,在路床底面、路堤底面及此两层中间部位台阶各铺设一层土工格室,构成具有较高的侧向限制和防滑,防变形、有效的增强路基的承载能力和分散荷载作用,新老路基交界处及新路基采用了强夯和碾压两种方式进行路基的补强,有效了加强了路基的稳定性。
