SOLIDIFYING MATERIAL OUTFLOW PREVENTIVE METHOD FROM ELEMENT IN STEEL UNDERGROUND CONTINUOUS WALL CONSTRUCTION METHOD AND STEEL UNDERGROUND CONTINUOUS WALL MEMBER USED THEREFOR

摘要

PROBLEM TO BE SOLVED: To completely restrain the outflow of a solidifying material such as a concrete filled at preceding element execution work even if an excavating wall surface is not smooth. ;SOLUTION: In this steel underground continuous wall construction method, excavation is performed while stabilizing a groove wall by a stabilizing liquid, and after completing the excavation equivalent to the preceding element section length, steel underground continuous wall member 1A to 1E are built up while mutually connecting these, and next, after placing foot protection concrete 12 under the steel underground continuous wall members 1A to 1E, concrete is filled inside an excavating groove. Above preceding element execution prevents the outflow of a solidifying material such as the concrete filled by arranging packer bodies 6, 6 by filling mortar or concrete brought into close contact with an excavating groove wall on an outside surface of the steel underground continuous wall members 1A to 1E arranged in both end parts among the plural underground continuous wall members 1A to 1E.;COPYRIGHT: (C)2000,JPO
