　　Along the slope, the elevated track descends from the ground into theunderground tunnel, 500 meters north of Yufu River Station, one station of R1 line. N-shaped steel frame structures have been set up above the track and soundproof plates are also installed on the top, forming a 150-meter-long rain shed, preventing rainwater entering the underground tunnel and protecting trains moving from opposite sides at the same time.
