中国石油天然气总公司工程技术研究所研制的水下不分散混凝土在热带海洋工程应用成功,取得了显著的技术、经济和社会效益。该工程地处南海南部某礁盘上,其基础部分皆在水面以下,包括机场、码头、引桥的水下基础及主体工程的水下地基梁,从水下到水上的砌体工程、钢筋混凝土柱、钢筋混凝土防护墙及位于飞溅区的钢筋混凝土梁和板等。竣工后经各方联合总结确认: (1)由于采用水下现浇现砌结构,提高了结构整体性和稳定性,混凝土标号为350号以上,满足了设计要求。 (2)由于采用常规陆地方法施工水下工 The underwater non-dispersed concrete developed by China National Petroleum Corporation’s Engineering Technology Research Institute has been successfully applied in tropical ocean engineering and has achieved significant technical, economic, and social benefits. The project is located on a reef plate in the south of the South China Sea. Its basic parts are all below the surface of the water, including the underwater foundations of airports, docks, approach bridges, underwater foundation beams of major works, masonry projects from underwater to water, reinforced concrete. Columns, reinforced concrete protective walls and reinforced concrete beams and slabs in the splash area. After the completion of the project, the parties jointly confirmed and confirmed: (1) Due to the adoption of underwater cast-in-situ bricklaying structure, the structural integrity and stability are improved, and the concrete number is 350 or more, which meets the design requirements. (2) Submarine workers due to the use of conventional land methods
