土工网栅是一种工程材料——土工织物中最新的一种产品。开孔的网格结构在道路工程上使用时,土或集料在孔眼中联锁起来,每个网肋的作用相当于一个独立的锚固点。它在道路结构层次中的抗拉强度能有效地得到发挥。国外土工网栅与塑料编织物、合成纤维无纺织物一样,都已在道路工程上应用;在我国,前者正在进行产品开发,后者在土建工程部门已起步应用。由于土工网栅在工程方面会有更多的用途,现予以介绍。
Geogrid is an engineering material - the latest geotextile product. Open-hole grid structure used in road engineering, soil or aggregate interlock in the hole, each mesh rib acts as an independent anchor point. Its tensile strength at the road structure level can be effectively exerted. Foreign geogrids and plastic braid, synthetic fiber non-woven fabrics, have been applied in road engineering; in our country, the former is ongoing product development, the latter has begun in the civil engineering sector applications. As the geogrid will have more uses in engineering, I will introduce it now.
