摘要:: 近些年来,江苏水利建设进入了高峰阶段,尤其是大型水利枢纽建设,南水北调东线江苏段、走马塘江边枢纽、新沟河江边枢纽等一大批水利枢纽已建成投入运行。目前新孟河界牌枢纽、奔牛枢纽等大型枢纽工程也已进入施工阶段,对于泵站大体积混凝土施工,尤其是异型结构部位的施工采取措施防止或是减少混凝土裂缝的产生一直是施工的重点、难点。因此,有必要在建设施工的过程中,对防裂措施进行持续不断的总结与研究,最大限度的积累宝贵经验,从而为今后的建设施工提供正确指导。结合常州市金坛区龙山水利枢纽工程的实际施工情况,就泵站流道层混凝土施工防裂措施进行了研究与分析,探讨有效对策。

Abstract:: In recent years, the water conservancy construction of Jiangsu Province has stepped in rapid period, especially in the construction of large water conservancy project. A number of water conservancy project have been placed in service, such as Jiangsu section of South-to-North Water Diversion Project, Zoumatang Riverside Water-control Project, Xingou River Water-control Project. At present, the large water-control projects such as the Jiepai hydro-junction of Xinmeng River and the Benniu hydro-junction had also entered the construction phase. Taking measures to prevent the occurrence of concrete cracks had always been the focus and difficulty in pump station construction, especially the construction of special-shaped structural parts. For the reason, it's necessary to continuously study the anti-crack measures and accumulate valuable experience during the construction process, so as to provide guidance for future water conservancy construction. Based on actual construction of Longshan hydro-junction in Changzhou City, the anti-crack measures of the concrete construction in flow runner of the pump station were studied and analyzed, and effective countermeasures were discussed.
