CONSTRUCTION METHOD FOR UNDERGROUND DOUBLE WALL, AND UNDERGROUND DOUBLE WALL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To improve work efficiency and shorten a construction period in a construction method for an underground double wall in which a lamination panel is used as a form for placing concrete to become a permanent form for constructing the double wall. ;SOLUTION: As a method for simultaneously forming an outer side wall and an inner side wall in an underground outer wall, a placing type form panel 1 comprising a synthetic resin foam plate 2 and a plate body 4 having water permeability laminated with each other, and having a drain space 3 in a lamination surface of the synthetic resin foam plate 2 and the plate body 4 is installed to set the plate body 4 on the outer side wall side, and to provide a specified gap between a soil retaining wall and an inner form for the inner side wall. Concrete is simultaneously placed on the outer side and the inner side of the placing type form panel 1 to form the outer side wall and the inner side wall.;COPYRIGHT: (C)1999,JPO
