Study on Application of Extrusion Concrete Side Wall in Concrete Face Rock Fill Dam

Abstract:

Compared with the traditional upstream dam slope construction method, the extrusion side wall technology has many advantages. such as less process steps, little interference, quick construction speed etc ,So it arouse more and more attention in the engineer design and construction fields . The technology of extrusion concrete side wall applied to the construction of concrete face rockfill dam in the Bailian river storage power station, machinery and equipment were used on the cushion material to form a concrete wall extrusion , which avoid the traditional process of Ultra-filled cushion material, rolling slopes, cut slopes and other complicated process, not only ensure the quality, but also improve the stress state of the panel.
