钢材钢筋混凝土无梁岔管与无架钢岔管与其它梁式禽管相比，具有受力条件好、钢管较薄、施工方便等优点，是一种新的会管结构型式，特别适合于中高水头的中小型水电站．通过一个大比尺物理模型试验，对钢衬钢筋混凝土无梁岔管的承载机理和结构特性进行了深入的研究，取得了令人满意的结果．
Compared with other beam tubes, the steel reinforced concrete beamless bifurcated bifurcated billet has the advantages of good stress conditions, thin steel tubes and convenient construction, and is a new type of tube-and-tube structure, which is especially suitable for Medium and high head of small and medium hydropower stations. Through a large-scale physical model test, the bearing mechanism and structural characteristics of steel-lined reinforced concrete beamless bifurcated pipe are studied in depth and satisfactory results are obtained.
