摘要
北京市北护城河综合治理工程,设计要求原河道混凝土挡墙部分拆除后不影响剩余部分的使用功能,以保证其与新建挡墙连接的工程质量。为保证施工质量和环保采用静态破碎方法,通过现场试验,确定了挡墙拆除的静态破碎设计参数,取得了良好效果。
In the comprehensive rehabilitation project of Beijing North Moat, according to the design requirement, the function of the remained part of the moat should not be affected after some of the original retaining wall is dismantled so as to ensure the quality of its connection with new wall. Therefore, soundless cracking method is adopted and the cracking parameters are determined by site test, reaching a good effect.
