Existing expressway (railway) embankment lightening settlement control method
The invention discloses an existing expressway (railway) embankment lightening settlement control method. Steps are dig in slopes at two sides of a road as construction platforms; drilling holes are arranged in construction areas; the drilling holes are dripped into embankments according to certain inclined dip angles; in the drilling process, soil is automatically discharged from spiral drill rods; after the drilling is finished, PVC pipes are inserted in; bagged sands are filled into the PVC pipes, and the exposed ends are added with PVC pipe sealing covers; the replacement of the drilling holes in whole construction sections is finished; the slopes are backfilled by light soils for protecting the slopes again; and the backfilled sands filled in the PVC pipes are taken out every period of time according to actual conditions of highway differential settlement so as to achieve the settlement control effect. The traffic is normal in construction; the drilling holes little damage pavement structure layers; and the PVC pipes replace the embankment backfilled soils to achieve the effect of lightening the weight of the embankments, so that the roadbed post-construction settlement is largely reduced. The method is simple and clear in construction procedures, convenient for construction, economic, efficient and excellent in implementation effect.
