大型渡槽机械化施工方案和工艺研究

通过对不同施工方案的对比分析,沙河渡槽工程最终采用了整孔渡槽预制架设施工方案.大型渡槽机械化施工装备包括提槽机、运槽机和架槽机3台设备,工艺主要有渡槽的提运架施工工艺、驮运架槽机返回制槽场施工工艺和架槽机整体转线工艺.经工程实践,施工工艺方案合理,较好地满足了依托工程施工要求,对大型调水工程的渡槽建设具有现实意义.

Research on Scheme and Process of Large-scale Aqueduct Mechanized Construction

Through the comparative analysis to different construction schemes, prefabrication and erection construction scheme is adopted to Shahe Aqueduct Project. The complete set of equipment mechanized to erect large-scale aqueduct mainly includes a machine to raise aqueduct, a machine to transport aqueduct and a machine to erect aqueduct. And its corresponding construction process mainly includes construction process of raising, transporting and erecting aqueduct, construction craft of entire transporting the machine to erect aqueduct, and process of entire transforming way by erecting aqueduct machine. Through practicing, this kind of construction process and scheme is reasonable. It can meet the requirement of project construction well. This will have a practical and immediate significance to build large-scale aqueducts in large-scale water transfer projects.
