公路与桥梁的加固 Reinforcement of highways and bridges

土工格栅是一种主要的土工合成材料，与其他土工合成材料相比，它具有独特的性能与功效。常用作加筋土结构的筋材或复合材料的筋材等。

Geogrid is a major geosynthetic material, which has unique performance and efficacy compared to other geosynthetic materials. Commonly used as reinforcement for reinforced soil structures or composite materials.

土工格栅分为塑料土工格栅、钢塑土工格栅、玻璃纤维土工格栅和聚酯经编涤纶土工格栅四大类。格栅是用聚丙烯、聚氯乙烯等高分子聚合物经热塑或模压而成的二维网格状或具有一定高度的三维立体网格屏栅，当作为土木工程使用时，称为土工格栅。

Geogrids are divided into four categories: plastic geogrids, steel plastic geogrids, glass fiber geogrids, and polyester warp knitted polyester geogrids. Grille is a two-dimensional grid or three-dimensional grid with a certain height formed by thermoplastic or molded high polymer materials such as polypropylene and polyvinyl chloride. When used in civil engineering, it is called a geogrid.

该产品主要用于煤矿井下开采时的护帮，可作为锚杆巷道、支护巷道、锚喷巷道等多种巷道的支护材料。

This product is mainly used as a support material for various tunnels such as anchor bolt tunnels, support tunnels, and anchor spray tunnels during underground coal mining.

用于假顶时，双层以上联合使用。适用于各种堤坝和路基补强、边坡防护、洞壁补强，大型机场、停车场、码头货场等永久性承载的地基补强。

When used for false roofs, use a combination of two or more layers. Suitable for various types of embankment and roadbed reinforcement, slope protection, tunnel wall reinforcement, and permanent bearing foundation reinforcement for large airports, parking lots, docks and freight yards.

场地的不同、地势的不同、使用的材料也不相同，材料再好也不行，只有合适才最重要。

The different sites, terrain, and materials used are also different. No matter how good the materials are, they cannot be used. Only suitable ones are the most important.
