摘要
本工程为了防止挡土墙因地基不均匀沉降、温度变化或采用不同基础引起挡土墙裂缝而破坏,设置2cm变形缝,传统的变形缝防水做法是利用止水铜板和沥青槽、沥青盒相结合,施工时需要先将安装止水铜板的结构施工段先浇筑,并将沥青槽、沥青盒安装在变形缝处,再浇筑与之相临的施工段,工序繁琐,耽误工期,且相邻段变形缝处模板不易安装。采用分段浇筑混凝土变形缝油浸木板配合木方处理后整体浇筑施工技术,变形缝处填充2cm厚油浸木板既可以作为防水材料,又可以作为模板,且宽度与结构墙体厚度一致,结构墙体内侧模板和外侧模板不需要在变形缝处断开,更易于安装。通过此技术,提高了施工质量和安全,缩短了工期,降低了施工成本。
In order to prevent the retaining wall from being damaged by uneven settlement of foundation,temperature change or cracks caused by different foundations,a 2 cm deformation joint is set up in this project.The traditional method of waterproofing deformation joint is to use the combination of water-proof copper plate,asphalt groove and asphalt box.It is necessary to first pour the structural construction section with water-proof copper plate in construction.And the asphalt groove and the asphalt box are installed at the deformation joint,and then the adjacent construction section is poured.The process is tedious and the construction period is delayed,and the template at the deformation joint of the adjacent section is not easy to install.The construction technology of oil-immersed wood board with deformed joints and wood square treatment is adopted.The 2 cm thick oil-immersed wood board filled with deformed joints can be used as both waterproof material and formwork,and the width is the same as the thickness of the structural wall.The inner and outer formwork of the structural wall need not be disconnected at the deformed joints.Easy to install.Through this technology,the construction quality and safety are improved,the construction period is shortened and the construction cost is reduced.
