基础工程底板及墙体替换后浇带施工技术

Replacing Post Pouring Belt Construction of Foundation Slab and Wall

黑龙江省博物馆新馆工程原设计有一条伸缩缝,地下墙体为超长墙体,基础设置后浇带或加强带。后来为了减少墙体裂缝、节约工期,地下墙体在室外地坪以下增加墙体连梁、构造柱,采取在墙上预留洞口、调整钢筋布置等措施。同时基础底板设置地沟代替后浇带。

Heilongjiang New Museum project had an expansion joint for original design,and the underground wall was super long wall,so the post pouring belt and strengthening belt were set for foundation. In order to reduce cracks of wall and save period,the methods of adding connection beam and structural columns of underground wall below the outdoor floor,reserving holes in walls and adjusting steel bars arrangement are applied. Meanwhile,the trench is set to replace the post pouring belt.
