As the tunnel slope Yang Import & Export mainly by gravel slope soil composition, and Myeong-hole after excavation, in a timely manner while, Yang slope reinforcement, to ensure slope stability, slope facilities for the mortar along the bolt, hanging steel net injection concrete reinforcement; s

As the tunnel import and export side slope upward slope, mainly by gravel layer constitutes a hole after excavation and Myeong-dong, Songpa-gu, and lift up timely to side with reinforcement to ensure stability of a slope, on the slope surface for mortar shank, hanging Rebar Web shotcrete reinforceme

Because the tunnel import and export side slope supine slope mainly by the crushed stone soil layer constitution, after Dongkou and clearly opens wide digs side, promptly carries on, supine slope reinforcement processing, guarantees the stability of slope, executes along the slope face makes the mor

Due to import and export primarily made up of gravel soil on the slope upward slope of the tunnel, the entrance and after excavation of Myeongdong, edges, inverted slope reinforcement in a timely manner to ensure slope stability along the slope effect of mortar bolt, hang steel fabric shotcrete rein
