Construction method adopting rhombic geogrid
The invention provides a construction method adopting rhombic geogrids, and belongs to the technical field of roadbed filling. The construction method comprises the steps that a base layer of a roadbed is backfilled, compacted and flattened, rhombic geogrids are laid, the side, away from a lap joint part, of a roadbed is fixed through a plastic steel belt, pipe pieces and U-shaped nails, the lap joint part is fixed through the plastic steel belt, the pipe pieces and the U-shaped nails, and padding is used for paving and compacting after fixing. According to the method, plastic steel belts areinterwoven to penetrate through lattices of the rhombic geogrid; by adopting a U-shaped nail anchoring mode, the tensile strength and the stability of the lap joint of the rhombic geogrid can be effectively improved, the flatness of the rhombic geogrid, excessive stretching of the rhombic geogrid and edge curling are effectively controlled, the risk of later rework treatment is reduced, and the roadbed filling construction quality is greatly improved.
本发明提供一种采用菱形土工格栅的施工方法，属于路基填筑技术领域。本施工方法包括对路基的基层回填、压实平整，铺设菱形土工格栅，远离搭接部的一侧使用塑钢带、管片和U型钉固定，搭接部处使用塑钢带、管片和U型钉固定，固定后使用填料摊铺、压实。本方法采用塑钢带交织穿过菱形土工格栅的格子，使用U型钉锚固方式，可有效加大菱形土工格栅搭接处的抗拉强度和稳定性，菱形土工格栅平整度、菱形土工格栅的拉伸过量、卷边均得到了有效控制，降低了后期返工处理的风险，大大提高了路基填筑施工质量。
