生态袋用于道路边坡防护施工工艺研究

Study on Construction Technology of Ecological Bag Used for Road Slope Protection

对生态袋用于道路边坡的稳定性、生态袋纤维尺寸及生态袋护坡施工工艺进行研究,提出了采用生态袋进行道路边坡防护的施工流程和施工质量控制要点。结果表明,生态袋护坡的稳定性主要来源于其三角形结构工法、工程扣的连接作用以及植物根系的稳定作用;生态袋的纤维宽度明显粗于普通土工袋纤维,使生态袋具有更好力学强度;生态袋护坡施工工艺流程主要包括生态袋布置及摆放、回填土层和系统排水,必要时可采用加筋格栅网反裹进行稳定;生态袋布设方式、生态袋夯实和排水系统布设是影响生态袋护坡施工质量的主要因素。

The stability,fiber size&construction technology of ecological bag used for road slope protection are studied,and the construction process&quality control points of ecological bag used for road slope protection are proposed.The results show that the stability of the ecological bag slope protection mainly comes from its triangular structure construction method,the connection of engineering buttons&the stability of plant roots.The fiber width of the ecological bag is obviously thicker than that of the ordinary geotextile bag,which makes the ecological bag have better mechanical strength.The construction process of ecological bag slope protection mainly includes the layout and placement of ecological bags,backfilling soil layer and system drainage.If it is necessary,reinforced grid mesh can be used to reverse wrap for stabilization.The layout mode of ecological bags,compaction of ecological bags&layout of drainage system are the main factors affecting the construction quality of ecological bag slope protection.
