Concrete cutoff wall is an effective treatment Danger foundation seepage and seepage engineering technology, which is pervious foundation in loose or dam ( weir ) continuous pore into the body groove to the solid wall of mud , the mud under pouring concrete or other impervious material backfill construction made ​​from the seepage of underground continuous wall effect . With the development of science and technology , the construction process and impermeable material has been greatly improved and progress. Because plastic concrete material constituents and more complex mix design , strict quality control , which are for cut-off wall construction increases the cost. This paper outlines the first wall construction technology development status at home and abroad , several wall materials and their corresponding characteristics , combined with Wudu reservoir cofferdam , on the use of plastic concrete cutoff wall materials theoretical and experimental research, including wall construction using mud , CUTOFF raw materials, cut-off wall construction technology ( construction platform arrangement, temporary construction system layout , slot segment is divided , the joint hole construction , quality control, exception handling , etc. ) for construction of the actual situation , design a suitable project mix and apply them , and finally under construction , conduct comprehensive evaluation, to meet the cofferdam seepage requirements, to achieve good results , the abolition of the next deep curtain Grouting for the project to save the investment . Results of their research in Wudu reservoir cofferdam the successful use , not only for other dam seepage reinforcement with reference, but also for technical research of dangerous reservoirs accumulated experience .
