土工程物是用聚丙烯纤维旋绕粘压而成。它有一定厚度,柔软,而且具有力学强度,在工程中能起到排水(过滤)、隔离、加固的作用,可用于公路、管道、堤坝、河道等工程中。在易于翻浆的地带筑路时,先将土工织物铺于已挖好的土基上作过滤垫层,然后再铺砾石、石渣,最后做沥青或 Earthwork is made of polypropylene fiber spiral wound pressure. It has a certain thickness, soft, and has mechanical strength, can play a drainage (filtration), isolation, reinforcement role in the project, can be used for road, pipelines, dams, rivers and other projects. When it is easy to turn over the roads, geotextiles are laid on the dug foundation so as to make the filter mat, then gravel, gravel and finally asphalt or
