【Features】 ○ Smooth installation work can be carried out even in narrow construction yards. ○ The loading operation (crane work) and installation work (horizontal pulling work) can be separated, allowing for rapid construction. ○ The excavation width is smaller compared to conventional methods. ○ Once the cover plates are installed, work can be conducted underground, allowing traffic above to remain open. ○ There is no need for the crane to move during installation, allowing for placement at a single lowering location. ○ Ideal for construction in densely populated residential areas, under busy roads, and for crossings under bridges and railways. ○ Installation work is possible even in areas with overhead obstacles such as elevated bridges and power lines. ○ The friction between the box culvert and the foundation is low, reducing the vertical PC tension to below 50%. ○ Construction is possible with a longitudinal slope of up to 10%. *For more details, please inquire.
