压力循环式灌浆在南运河坝体防渗工程中的应用

Application of Pressure Cyclic Grouting in Dam Anti-seepage Project in the South Canal

2003年、2004年引黄济津期间南运河持续高水位运行,致使沧州市城区个别堤段出现渗水、泥托、管涌等险情,必须采取措施进行防渗处理。文中针对南运河沧州市城区段堤防的防渗加固处理进行了处理方案的选择和施工方案的设计。

The South Canal continued high water level operation during the period of diversion Yellow River water to Tianjin,resulting in water seepage,mud care,piping and other dangerous situations in individual embankment of Cangzhou City,and the measures had to been taken as soon as possible to control the seepage.Aiming at the anti-seepage and reinforcement of embankment in Cangzhou urban section of the South Canal,the treatment scheme is chosen and the construction program is designed.
