Civil grid

Abstract

The utility model discloses a civil grille. The civil grid comprises a plurality of parallel vertical grid bars, the upper end faces of the vertical grid bars are provided with equal-length semicircular protrusions, and the two sides of the vertical grid bars are provided with first water guide channels. The transverse grid bars are fixed among the vertical grid bars, the upper end faces of the transverse grid bars are provided with equal-length arc-shaped protrusions, the two sides of the transverse grid bars are provided with second water guide channels, and the first water guide channels are communicated with the second water guide channels through first notches in the vertical grid bars; the drainage strips are fixed to the two ends of the vertical grid bars, drainage cavities are formed in the drainage strips, the two ends of the first water guide channel are communicated with the drainage cavities through second notches, and drainage openings are formed in the drainage strips. According to the soil-wood grating, a complete drainage system is constructed, efficient drainage is achieved, water accumulation is avoided, and meanwhile drainage is assisted through a unique surface structure. In addition, water accumulation is avoided, the engineering stability and durability can be improved, friction force between the geogrid and a soil body is maintained, the reinforcement effect is stabilized, aging corrosion of the geogrid is delayed, the service life is prolonged, and the maintenance cost is reduced.
