Selecting an appropriate slope protection scheme is particularly important in road construction projects. Let the timeliness of steel-plastic grills and other products be infinitely extended. In the past construction process, pure masonry structures such as face walls, shotcrete, spray-mix, anchor shotcrete, and other pure masonry structures were mostly used for slope protection. Although its initial durability and anti-corrosion effect are better, as time progresses, the effect will gradually weaken due to weathering of rocks, aging of concrete, and corrosion of steel bars.
The most important aspect of a revetment project is foot protection. If the foot protection project is not done well, it will erode during washing and the block stones of the foot protection will be damaged in a large area. Therefore, during construction, the riprap revetment should extend downstream. Anticipated washout area outside. When installing the geotextile filter layer, the continuity of the geotextile should be ensured, so that it does not cause poor contact between the geotextile and the soil when the geotextile is bent and folded.
Non-woven geotextile is a network made of irregularly arranged fiber ties and needles. Commonly used are needle-punched non-woven geotextiles. This type of geotextile has strong compressibility, large porosity, and good water conductivity, which is better than woven geotextile.
Geotextiles have many functions such as anti-seepage, reverse filtration, drainage, isolation, reinforcement, protection, and sealing. Compared with conventional masonry and concrete materials, it has the advantages of low investment, simple construction technology, short construction period, good penetration effect, and high channel effective utilization coefficient.
