PURPOSE: A bidirectional extendable ground reinforcing device and a construction method thereof are provided to perform tension work with less power by successively expanding two fixing wings. CONSTITUTION: A bidirectional extendable ground reinforcing device comprises first and second fixing wings(10,20), tensile members(30,40), an expansion guide(50), and a packer(60). The first and second fixing wings are settled on ground. The tensile member respectively extends first and second fixing wing. The expansion guide directly or indirectly supports first and second fixing wing. The packer supports the expansion guide with an anchor hole(1). |
