Double-steel-plate concrete combined pipeline welded with spaced square steel pipes and construction method
The invention discloses a double-steel-plate concrete combined pipeline welded with spaced square steel pipes and a construction method, the combined pipeline is formed by splicing a plurality of double-steel-plate concrete combined pipe pieces in the circumferential direction and is prefabricated in a segmented mode in the length direction, and adjacent pipelines are connected in a welded mode. The combined segment comprises an arc-shaped outer steel plate, an arc-shaped inner steel plate, side plates arranged at the ends of the arc-shaped outer steel plate and the arc-shaped inner steel plate, square steel pipes arranged between the arc-shaped outer steel plate and the arc-shaped inner steel plate, perforated rib plates arranged between the adjacent square steel pipes, and interlayer concrete filled between the adjacent square steel pipes. A double-steel-plate concrete combined structure is adopted, the advantages of being high in overall strength, good in stability performance, good in economical efficiency and the like are achieved, the square steel pipes are connected with the inner steel plate and the outer steel plate, the overall rigidity of the pipeline is improved, and local buckling of the steel plates is prevented; the perforated rib plates are welded to the adjacent square steel pipes, and the cooperative work capacity of the steel pipes and interlayer concrete is improved; and the transportation efficiency of the duct pieces is improved, and wide engineering application prospects are achieved.
本发明公开了一种焊接间隔方钢管的双钢板混凝土组合管道及施工方法，组合管道沿环向由若干个双钢板混凝土组合管片拼接而成，沿长度方向分段预制，相邻管道焊接连接。组合管片包括弧形外钢板，弧形内钢板，设置于弧形外钢板和弧形内钢板端部的侧板，设置于弧形外钢板和弧形内钢板之间的方钢管，设置于相邻方钢管之间的开孔肋板，填充于相邻方钢管之间的夹层混凝土。本发明采用双钢板混凝土组合结构，具有整体强度高，稳定性能好，经济性好等优势，方钢管连接内外钢板，提高管道整体刚度，防止钢板局部屈曲，相邻方钢管焊接开孔肋板，提高钢管与夹层混凝土的协同工作能力，钢管内部空心减轻管道自重，提高管片的运输效率，具有广阔的工程应用前景。
