Technics experiment of the concrete anti-seepage wall at Lucun reservoir;

Mix proportion and physical and mechanical properties are studied on tow typesof cut-off wall concrete which properties are completely different.

Then,disfigurements are found on the concrete impervious wall.

The issue,introduced Laohutou Reservoir,and explains the identification of using concrete impervious wall for the dam s body and curtain grouting for the foundation of the dam through analyzing on venue arrangement,applicable con- ditions,reliability of the technology and job practice challenges.

To prevent environment pollution,the control measures of building concrete impervious wall along dam axial line,reconstructing drainage mound and adding spillway basin as well as paving with reinforced concrete are taken in design.
