Fabricated double-steel-plate concrete combined pipeline and construction method
The invention discloses an assembly type double-steel-plate concrete combined pipeline and a construction method. The combined pipeline is composed of a plurality of double-steel-plate concrete pipe piece units in the annular direction, the adjacent pipe piece units are connected and fastened through annular joints and are prefabricated in a segmented mode in the length direction, and the adjacent segments are connected and fastened through vertical joints. Each double-steel-plate concrete pipe piece unit comprises a pipe piece unit shell and interlayer concrete poured into the shell. The segment unit shell is formed by welding an arc-shaped outer steel plate, an arc-shaped inner steel plate and a Z-shaped side plate. And the Z-shaped side plate is provided with an embedded bolt group. A double-steel-plate concrete combined structure is adopted, the advantages that steel is tensioned and concrete is pressed are fully played, the overall rigidity and crack resistance of the pipeline are improved, the steel plates serve as formworks for pouring concrete, the inner wall of the pipeline is smooth, the water passing capacity is high, the pipe piece units are connected or welded through bolts, construction is easy and convenient, and connection is reliable; wide engineering application prospects are realized.
本发明公开了一种装配式双钢板混凝土组合管道及施工方法，所述组合管道沿环向由多个双钢板混凝土管片单元组成，相邻的管片单元通过环向节点连接紧固，沿长度方向分段预制，相邻各段通过竖向节点连接紧固。所述双钢板混凝土管片单元包括管片单元壳体和浇筑于壳体内的夹层混凝土。所述管片单元壳体由弧形外钢板、弧形内钢板和Z形侧板焊接而成。所述Z形侧板设有预埋螺栓组。本发明采用双钢板混凝土组合结构，充分发挥钢材受拉和混凝土受压的优点，提高管道的整体刚度和抗裂能力，钢板充当浇筑混凝土的模板，管道内壁光滑，通水能力强，管片单元采用螺栓连接或焊接，施工简便，连接可靠，具有广阔的工程应用前景。
