SLAB TRACK STRUCTURE FOR RAILWAY WITH LATTICE APPROACH BLOCK, AND CONSTRUCTION METHOD FOR THE SAME

摘要

Provided are a railway slab track structure comprising a lattice approach block and a construction method thereof. A concrete horizontal member supports vertical load, as a concrete lattice frame structure of the lattice approach block moves to a Rahmen. A concrete longitudinal member functions as a column to support vertical supporting power. A joint of a structure for a bridge or a rail way has the concrete longitudinal members, which are different in length from each other, consecutively arranged on concrete-treated gravel thereof to gradually change vertical support stiffness. The lattice approach block has more excellent construct ability and properties than those of an existing lattice approach block so as to prevent a concrete slab track from sinking and being cracked after the concrete slab track is installed.
