南水北调温博段倒虹吸混凝土浸蚀分析

南水北调工程温博段倒虹吸工程建成后,其混凝土受到临近工业污水的影响,表层沉积砖红色沉淀,可能对混凝土质量造成影响。通过钻芯取样、环境水分析及硫酸盐浸入深度分析等方式对混凝土受浸蚀状况进行分析,并对目前混凝土质量进行了评定。

Analysis on the Concrete Erosion of the Inverted Siphon at Wenbo Section,South-to-North Water Diversion Project

After the completion of the construction of the inverted siphon of Wenbo section in the south-to-north water diversion project , impacted by the industrial waste water nearby, the concrete surface is covered by some brick-red sediments, which may impact the con-crete quality.In this paper, the concrete erosion is analyzed and the concrete quality is appraised by core sampling, the analysis of envi-ronmental water and erosion depth of sulphate.
