污水处理厂地下连续墙施工关键质量控制措施

Quality control measures of key process of underground diaphragm wall construction in sewage treatment plant

地下连续墙因其整体性强、抗渗效果好,在深基坑围护中得到广泛的应用。通过对竹园污水处理厂调蓄池项目地下连续墙基坑围护工程施工关键工序质量控制进行介绍,总结质量控制要点。主要包括三轴搅拌桩槽壁加固,成槽质量、十字钢板接头处理、刷壁次数和沉渣厚度及钢筋笼吊装、水下混凝土浇筑工序中质量控制的重点,以供同类项目参考。

Underground diaphragm wall has been widely used in deep foundation pit enclosure because of its strong integrity and good impermeability.Talks about the storage tank project of Zhuyuan sewage treatment plant and summarizes the key points of quality control.It mainly includes the reinforcement of the wall of the three-axis mixing pile,the quality of the groove,the treatment of cross steel plate joint,the times of brushing the wall and the thickness of the sediment,the hoisting of the reinforcement cage and the key points of quality control in the underwater concrete casting process which can be taken as the reference of similar projects.
