LIGHTWEIGHT BANKING WITH RETAINING WALL

摘要

PROBLEM TO BE SOLVED: To prevent the increase of load to a retaining wall 1 following the compressive deformation of foam plates 2 by piling up the foam plates 2 with a clearance 5 to the retaining wall 1, without impeding concrete placing work for forming an upper concrete floor slab 7 even if piling up the foam plates 2 with the space 5 to the retaining wall 1 in lightweight banking with the retaining wall formed with the upper concrete floor slab 7 on the synthetic resin foam plates 2 piled up inside the retaining wall 1. SOLUTION: The foam plates 2 are piled up with the clearance 5 to the inner surface of the retaining wall 1, and the foam plates 2 in the uppermost stage are piled projecting onto the retaining wall 1 side to form an upper hood part 6 closing the clearance 5. Concrete is placed on the foam plates 2 in the uppermost stage including the upper hood part 6 to form the upper concrete floor slab 7. COPYRIGHT: (C)2005,JPO&NCIPI
