Deep overburden embankment dam corridor

The utility model discloses a both do benefit to the construction period construction, done benefit to the deep overburden embankment dam corridor of operation period maintenance again. This deep overburden embankment dam corridor includes riverbed corridor section and sets up in the bank slope at riverbed corridor section both ends corridor section, riverbed corridor section sets up on the riverbed overburden, bank slope corridor section by the domatic slope of the tip coast slope overburden of riverbed corridor section set up up after driving the surface soil bank slope overburden on the surface. Through setting up bank slope corridor section, reduced bank slope overburden excavation volume, shortened the time limit for a project, more do benefit to construction of dam foundation corridor, simultaneously, bank slope overburden excavation volume reduces and then has also reduced the embankment dam dam body and filled the material quantity, and bank slope section dam foundation grouting construction can fill with the dam body and go on in step, does not account for the sharp time limit for a project, in addition, at the embankment dam run duration, it is maintenance, the monitoring of dam body, the dam foundation and the cut -pff wall of opposite bank slope section more to do benefit to through this corridor.
