SPECIAL FEATURE STORY ON “Recent Diaphragm Wall Technologies and Future Challenge”
Hosoi Takeshi and Matsushita Shinya
ABSTRACT: Recent technologies for diaphragm wall are highlighted and their technical level is reviewed whether they meet the technical requirement and demand. Then their future views and challenges on the following technologies are discussed: slurry fluids, trench stability, concrete, rebar, slime removal, vertical accuracy control, low headroom machine, and machine for the installation of diaphragm wall underexisting structures.
KEYWORDS: Polymer, Trench stability, High grade concrete, Rebar cage movement, Slime removal, Base grouting, Vertical accuracy, Low-headroom excavator, Existing under-structures.
