The aesthetic beauty of the arch curve harmonizes with the surrounding environment! A pair of components is mutually installed, requiring no special technology or skilled workers.
"Texpan" is a two-part precast arch culvert method developed in France. Due to its unique arch shape, it can accommodate a soil cover of 30 meters even with a thin member thickness of 40 cm. It enables large spans of 20 meters, thereby realizing various internal cross-sections. By alternately combining reinforced concrete arch members, it creates space, and by placing fill on top, it can serve as an alternative to culverts and bridges. 【Features】 ■ Two-part precast arch culvert method developed in France ■ Members are installed in pairs, requiring no special technology or skilled labor ■ The aesthetic beauty of the arch curve harmonizes with the surrounding environment ■ Its unique arch shape allows for a soil cover of 30 meters even with a thin member thickness of 40 cm ■ Enables large spans of 20 meters and realizes various internal cross-sections *For more details, please refer to the PDF document or feel free to contact us.
