CONSTRUCTION METHOD FOR RAILWAY ROADBED

摘要

The present invention provides a construction method for a railway roadbed structure including: an external wall installing step for installing a pair of external walls (100) to be apart from each other; an internal wall installing step for installing a pair of internal walls (200) in the external walls to be apart from each other and forming a free space (a) between the external walls (100) and the internal walls (200); a reinforcing material installing step for installing a reinforcing material (300) inward of the external wall (100); a hardening step for placing and hardening a filling material between both internal walls (200) and forming a filling part (400); a free space charging step for charging the free space (a) with a charger. The construction method for railway roadbed structure can reduce construction period and can facilitate construction.
