本文介绍了燕莎中心地下室底板大体积自防水混凝土工程,在不设防水层、未掺用防水剂、膨胀剂条件下的施工技术,达到国内民用建筑工程领先水平;底板不设后浇施工缝所采取的一系列措施,对在大体积现浇混凝土结构中取消后浇施工缝进行了有益的探索。
This article introduces the large-volume self-water-repellent concrete project of the Yansha Center basement floor. The construction technology under the condition of no waterproof layer, no water repellant and expansion agent is used, and it reaches the leading level of domestic civil construction projects; the floor does not have post-cast construction joints. A series of measures have been taken to explore beneficially the elimination of post-cast construction joints in large-scale cast-in-place concrete structures.
