新型的非实体三角形框架钢筋混凝土坝垛代替了过去惯用的由帚料、石料、土料等组成的实体坝垛,在黄河险工段已推广应用一百多座,起到了缓流落淤效果。该坝垛易于组装,施工方便,安全可靠,能长期使用。每个钢筋混凝土坝垛投资约八千元,比过去用帚石坝垛每个投资五万元,共为国家节省投资约三百万元。 The new type of non-solid triangular frame reinforced concrete dam instead of the past usual by the broom, stone, soil and other components of the physical dam stack, in the Yellow River work section has been promoting the use of more than 100 blocks, played a slow flow sedimentation effect. The dam stack is easy to assemble, convenient for construction, safe and reliable, and can be used for a long time. Each reinforced concrete dam investment about eight thousand yuan, than in the past with a broom stone dam every investment of 50,000 yuan, a total of about 3 million yuan for the country to save money on investment.
