Composite soft soil roadbed structure and construction method
The invention belongs to the technical field of road construction methods, and particularly relates to a composite soft soil roadbed structure and a construction method. The composite soft soil roadbed structure comprises conductive geotextile laid on a lower embankment, a geomembrane, a geogrid and composite conductive geotextile buried in a cushion layer. The conductive geotextile, the geomembrane, the geogrid and the composite conductive geotextile are all prepared by recycling one or more kinds of combined medical waste. The geomembrane is buried at a position 30cm below the upper embankment, thereby well realizing drainage and filtering; a 5cm rear clay transition layer is covered on the geomembrane, the conductive geotextile is arranged on the clay transition layer, the geogrid is buried between a lower roadbed and an upper embankment and plays a good role in reinforcement, and a layer of composite conductive geotextile is arranged at the cushion layer and can form a loop with the conductive geotextile, so that better drainage is achieved. The structure is simple in structure, high in practicability, convenient to construct and suitable for application and popularization.
本发明属于道路施工方法技术领域，具体涉及一种复合软土路基结构及施工方法。本发明提供了一种复合软土路基结构及施工工艺，包括平铺于下路堤的导电土工布、土工膜、土工格栅与埋于垫层的复合导电土工布。导电土工布、土工膜、土工格栅与复合导电土工布均由一种或几种组合医疗废物经回收处理制备而成，土工膜埋于上路堤以下30cm处，以很好实现排水及过滤，其上覆有一层5cm后粘土过渡层，导电土工布设于粘土过渡层之上，土工格栅埋于下路床与上路堤之间，起到很好的加筋作用，垫层处设一层复合导电土工布，可与导电土工布形成回路，更好排水。本发明结构简单，实用性强，便于施工，适合推广应用。
