The Research on Underground Cut-off Seepage Technology in Wanghe Groundwater Reservoir

摘要

Many cut-off schemes are contrasted on pervious foundation conditions in the project of Wanghe Groundwater Reservoir, the methods of HPGCW and VSMHPGCW are recommended, the construction technology and parameter about cut off wall are ascertained through field test, meanwhile, the joint questions on VSMCW and HPGCW are solved. In fact it is proved that HPGCW and VSMHPGCW have good cut-off effect, especially VSMHPGCW has better cut-off effect, lower cost.
