单支浅埋钢板桩围堰逆作法施工技术

The Reverse Construction Technology of Single Fulcrumand Shallow Burial Steel Sheet Pile Cofferdam

结合传统钢板桩围堰施工方法,对钢板桩围堰逆作进行了研究,采用将内支撑体系场内制作,整体吊装下放的方法,保证内支撑体系的施工质量,提高了现场施工进度。再者通过研究内支撑与导向架一体化施工方法,将钢围檩作为钢板桩插打施工导向架,从而保证了钢板桩插打的施工质量。

Combined with the traditional construction technology of Steel Sheet Pile Cofferdamstudied the construction technology of Steel Sheet Pile cofferdam Uni-axial on Water. Creative used of internal support system which maked inside and lifting down in all. This method guaranteed the construction quality of the internal support system,also improved the progress. In addition,combinedthe internal support system with the guide frame and used steel confining purlin as guide frame,which raised the construction quality of steel sheet pile.
