水下现浇模袋混凝土施工质量控制

在某预制场造船基地改造工程中,船舶下水滑道采用了水下现浇模袋混凝土的施工工艺。船舶下水方式为气囊滚动式下水。为保证船舶顺利下水,滑道的坡度及平整度是工程施工的控制重点。在以往的工程中,水下现浇模袋混凝土主要应用于护坡工程,对坡度及平整度的要求低于船舶下水滑道。针对水下现浇模袋混凝土和船舶下水滑道的特点,此工程在基床整平、模袋加工、模袋铺设和混凝土工程等方面进行了严格的施工质量控制,对施工细节进行了把握,取得了良好的效果。

Quality control of underwater construction of bagged cast-in-place concrete

The technology of underwater cast-in-situ molded concrete was adopted for the launchway in the renovation engineering of a shipbuilding yard.Vessels were launched into the water by the air bag.The slope and flatness of the launchway was the key for guaranteeing the safe launching of vessels.Underwater molded concrete was previously used for slope protection,the requirement of which to the slope and flatness was lower that for the launchway.According to the characteristics of underwater molded concrete and t...
