Abstract
The utility model provides a dam body integrally poured with concrete faceplates and rock filled concrete. Common concrete is poured both between filling rocks and an upper-stream template, and between filling rocks and a lower-stream template. Self-compaction concrete is poured inside the filling rocks, and the filling rocks and the self-compaction concrete form the rock filled concrete. The common concrete on the inner side of the upper-stream template forms an upper-stream common concrete faceplate, and the common concrete on the inner side of the lower-stream temperate forms a lower-stream common concrete faceplate. The filling rocks which are not poured are used as the templates, the process of constructing the templates on the inner sides of the faceplates is saved, expense is lowered, construction processes are simplified, and construction progress is improved. People do not need to wait for disassembling of the templates of the common concrete of the faceplates, can make overall arrangement and conduct rock filling in advance or conduct rock filling during the pouring process of the common concrete faceplates. Therefore, rock filling at the edges of the templates is avoided, the problem that rock filling at the edges of the templates during a rock filled concrete construction process is difficult is solved, use of manual labor in the construction process is reduced, and construction speed of the dam body is improved.
