摘　　要：针对新沟河江边枢纽船闸闸室施工特点、难点,分析闸室底板及墩墙是大体积混凝土、单节混凝土浇筑量比较大,质量要求高,特别是解决船闸闸室混凝土裂缝的施工通病和外观质量等问题,依据闸室施工工序,优化施工方案,分别从钢筋、模板制作安装,混凝土配合比、浇筑分层、温度控制、振捣、养护,墙后回填土,工程细节问题处理,质量评定情况等方面加以探讨,提出了相应技术措施控制。The characteristics and difficulties of riverside hub lock chamber in Xingouhe extension and dredging project are analyzed. The lock floor and pier wall is large volume concrete, single section concrete pouring quantity is large, quality requirements are high. For solving the common defects of cracks in concrete construction and appearance quality of lock chamber, according to the construction process, the construction program is optimized. Aspects as follow： fabrication and installation of steel and formwork, concrete mix ratio, pouring layer, temperature control, vibration, conservation, backfill behind the wall, other details and quality assessment of the project are explored. The corresponding technical measures are proposed.
