Research on the Design Scheme of Prefabricated Arch Skeleton for Embankment Slope
The traditional cast-in-place construction of railway subgrade slope protection projects has multiple molds,long construction period and difficult maintenance.Taking a certain railway subgrade slope protection project as an example,the design scheme of construction method of prefabricated arch skeleton for embankment slope is studied from five aspects:unit division,installation,connection,lifting and construction.A total of six types assembly units were set up,arranged from top to bottom and installed from bottom to top with mortise and tenon joints between units.lifting points were set on both sides of the unit's center of gravity for transportation and installation.Before installing the assembly units,cast-in-situ construction of the toe wall and skeleton bottom edge should be carried out to ensure the stability and smoothness of the prefabricated arch skeleton.
