摘　　要：水下升浆混凝土施工技术大大降低了临时围堰工程造价,为岩石地基条件下建造船坞及码头工程时预制钢筋混凝土沉箱的成功和广泛应用提供了可能。结合大型船坞工程水下抛石基床临时止水施工案例,对升浆混凝土临时止水的技术特点、工法程序、施工要点及质量控制内容等进行了叙述和分析,对于升浆施工过程中可能出现的技术问题给出了指导性建议。水下升浆混凝土施工技术有自己独特的工法,具有经济、方便、快速和安全的施工特点,可在同类工程中推广应用。The construction technology of underwater rising mortar concrete greatly reduces the engmeenng cost of temporary cofferdam, which makes it possible for the success and wide application of precast reinforced concrete caisson when building dock and terminal on the rock foundation. Combining with the project case of temporary water stop in the engineering of large docks, this paper analyzes the technical features, engineering methods and programs, construction points and quality control of temporary water stop construction of rising mortar concrete, and gives the instructive suggestions to the possible technological problems encountered in the rising mortar construction. The construction technology of underwater rising mortar concrete has its own unique construction methods and the construction characteristics of being economical, convenient, fast and safe, which can be extended in and applied to similar projects.
