Geotextile can filter, filter and reinforce in civil engineering. Because it is made of staple fiber by needling process, there will be countless small holes on the surface of the fiber, and there are root blocking. It has almost no effect.
The anti-seepage HDPE geomembrane has the characteristics of non-corrosion in strong acid-base environment for a long time, which is especially suitable for sewage treatment projects. In this paper, we will elaborate the selection of HDPE geomembrane materials, construction steps and technical points, and the matters needing attention in construction, so as to provide reference for relevant projects
In recent years, many geogrids have been designed by highway engineering. It has been proved that not only can the geogrid prevent asphalt pavement from cracking, reduce or delay the occurrence or reflection of cracks, reduce the rutting and wrapping of asphalt pavement, but also increase the fatigue life of a rigid substrate in half.
The geotextile roll shall be protected from damage before installation. The filament geotextile roll should be stacked in the area without water storage after leveling. The stacking height should not exceed the height width ratio of four rolls, and the identification film of the roll can be seen. Short wire geotextile roll must be covered with incomplete transparent raw materials to prevent UV embrittlement. In the whole process of storage, the details of identification and materials should be maintained.
The laying of woven geotextile should be determined according to the amount of labor in the construction of the backfill project. With the promotion of the backfill construction, the progress of the drainage board should be controlled at a distance of 3-5 meters in front of the backfill soil, so as to facilitate the maintenance of the drainage board. When the centralized laying method is adopted, the total laying area is not suitable to exceed 1000 m2 or the total construction area of the backfill project on that day Pile point compaction should be carried out to avoid wind turbulence and overturning drainage board and geotextile.
Many people think that they already know it very well after using geogrid used in mining for a period of time. They are not willing to take the initiative to learn more about the mining geogrid. In fact, this has some impact on the geogrid used in mining. You should search for more relevant content.
