| Abstract: | Based on the restoration project of the relief-well on Dingma section of Yangtze River Levee,the mechanical and chemical mechanisms are analyzed herein,and then a new technique for restoring the clogged relief-well,i.e.a piston-like deep drop-down well-flushing technique,is presented.Finally,the effect of the new well-flushing technique is demonstrated through the indoor and outdoor tests along with the actual application to Dingma section of Yangtze River Levee. |
