1、主要用于挡土墙、桥台、陡坡工程等;
1. Mainly used for retaining wall, abutment, steep slope engineering, etc.
2、挡 土墙和桥台属于受力结构体,承担外部所有荷载:主动土压力、结构体上部的动载、温度应力等,加筋材料长期处于较大的张力作用下,以及动载的反复作用下,材料的分子结构产生疲劳,其性能发生衰减,加速格栅的老化。为避免结构因加筋材料的蠕变而产生较大变形,应选择以高密度聚乙烯(HDPE)为原料的单向土工 格栅。
2. Retaining walls and abutments belong to stressed structures, which bear all external loads: active earth pressure, dynamic load on the upper part of the structure, temperature stress, etc. The reinforced materials are under the action of large tension for a long time, and under the repeated action of dynamic load, the molecular structure of the materials is fatigued, its performance is attenuated, and the aging of the grids is accelerated. Chemicals. In order to avoid large deformation caused by creep of reinforced materials, one-way geogrid with high density polyethylene (HDPE) as raw material should be selected.
