Embankment dam pitch core -wall base

The utility model discloses an embankment dam pitch core -wall base, its solved former embankment dam fill the in -process can not be enough in the problem that overflows. This embankment dam pitch core -wall base builds base face and base body including the base, the base is built the base face and is set up on the basement rock, ji mianshang is built at the base to the setting of base body, and the level that the level at base body top built the base face than the dam body is high. The level at base body top is higher than the level that base face was built to the dam body in this base, and consequently, this base exceeds the dam body to be built basic facial branch and can protect the sectional safety in dam body lower part, so the embankment dam can overflow filling the in -process, and then has reduced the height that the upper reaches set up the cofferdam, has reduced the quantity of diversion tunnel, has saved the investment, has practiced thrift the time limit for a project, has optimized the pivot and has arranged.
