Construction method of stone-filled embankment
The invention provides a construction method of a stone-filled embankment, and belongs to the technical field of highway engineering. The construction method of the stone-filled embankment comprises the steps of ground foundation bed treatment, surveying and setting out, roadbed stone filling and edge covering soil filling, geotextile and geomembrane laying, pipeline burying and soil roadbed layerlaying, and finally pavement structure layer laying on the soil roadbed layer. According to the construction method of the stone-filled embankment, the geotextile and the geomembrane are arranged, water on the upper portion of the roadbed is isolated, water on the upper portion of a road surface is prevented from entering the stone-filled roadbed to scour joint filling aggregates in gaps of the stone-filled roadbed, and the overall stability of the roadbed is guaranteed. Several pipelines are arranged above the geomembrane so that water at the upper part of the roadbed can seep into the pipelines and is intensively discharged into the excavated drainage ditches in the two sides of the roadbed, the soil roadbed layer plays a role in protecting the structure of the stone-filled roadbed through drainage of the water at the upper part of the roadbed, and the overall stability of the roadbed is further protected.
本申请提供了一种填石路堤的施工方法，属于公路工程技术领域。填石路堤的施工方法包括：地面基床处理、测量放线、路基的填石和包边土填筑，土工布以及土工膜的铺设、管道埋设以及土路基层铺设，最后在所述土路基层上铺设路面结构层。本申请提供的填石路堤的施工方法，设置了土工布和土工膜，对路基上部的水起到隔离作用，防止路面上部水进入填石路基中对填石路基缝隙中填缝粒料的冲刷，保证了路基整体稳定性。并在土工膜上方设置有若干的管道，使得路基上部的水能够渗流到各管道中，并集中排出至路基两侧开挖好的排水沟中，通过对路基上部水的引流，土路基层起到对填石路基结构的保护，进而保护了路基整体的稳定性。
