Construction method for treating soft soil roadbed through vacuum combined surcharge preloading method
The invention relates to a construction method for treating a soft soil roadbed through a vacuum combined surcharge preloading method, and belongs to the field of building construction. The method includes the steps of conducting roadbed cleaning in site and backfilling and leveling; stirring slurry to seal a wall; laying a medium-coarse sand cushion layer; inserting and hitting a plastic drainage plate; burying a monitoring and detecting instrument; conducting sealing ditch construction; embedding a vacuum pipeline and installing vacuumizing equipment; laying a layer of geotechnical cloth; laying three layers of sealing films layer by layer; conducting vacuumizing; laying a layer of the geotechnical cloth; laying a silty-fine sand cushion layer; grading and stacking to a full-load elevation; and unloading to a designed elevation. The vacuum combined surcharge preloading method is applied to soft soil roadbed construction, so that the drainage consolidation speed of the soft soil roadbed is increased, post-construction settlement is reduced, the stability of the roadbed in construction is guaranteed, roadbed construction is obviously accelerated, the construction period is greatly shortened, the safety is improved, and the construction quality is improved.
本发明涉及一种真空联合堆载预压法处理软土路基施工方法，属于建筑施工领域，通过场地清基及回填整平；泥浆搅拌密封墙；铺设中粗砂垫层；插打塑料排水板；监测检测仪器埋设；密封沟施工；埋设真空管路及抽真空设备安装；铺设一层土工布；分层铺设三层密封膜；抽真空；铺设一层土工布；粉细砂垫层；分级堆载至满载标高；卸载至设计标高。将真空联合堆载预压方法应用到对软土路基施工中，加速了软土路基排水固结的速度，减少工后沉降，施工中路基的稳定性得到保证，使路基施工明显加快，大大缩短了工期，安全性提高，提高施工质量。
