- Abstract
Taking the renovation project of un-dispersed underwater concrete on the main channel slope of South-to-North Water Transfer Project as the research object, the advantages and disadvantages of un-dispersed underwater concrete in underwater renovation were introduced. Combining with the damage situation of the main channel slope of South-to-North Water Transfer Project and the renovation design scheme, the pouch coagulation was achieved through field production test. The test objectives of soil-assisted pouring of large-volume underwater un-dispersed concrete and steel beam-assisted pouring of thin-wall underwater un-dispersed concrete were summarized. The advantages and disadvantages of the two pouring schemes were summarized and the pouring scheme of I-shaped steel truss beam-assisted underwater un-dispersed concrete with relatively simple construction and higher pouring efficiency was determined, which was more suitable for the underwater backfill and repair of bank slope of the main channel of South-to-North Water Transfer.
