沙漠地区输水工程关键技术研究与应用

Research and application of key technique for water conveyance project in desert zone

介绍了甘肃民勤调水工程在沙漠地区修建输水工程时线路选择经验及沙漠地基的工程地质特性,并主要针对输水建筑物的选型设计与施工,从基础开挖施工方法、地基及不良地基处理、一次现浇成形钢筋混凝土箱型暗渠施工及混凝土的后期养护技术等方面,阐述了工程主体建筑物的设计与施工技术的研究与应用。同时将对工程建设进程起决定性作用的沙漠地区施工道路的选线、设计施工这一关键技术做了论述,以此期望能对其他类似工程建设提供帮助及借鉴。

The experiences from the route selection and the engineering geologic characteristics of the foundation in the desert zone therein for the construction of the water conveyance works of Minqin Water Transfer Project in Gansu Province are introduced herein, and then the design of the main structures and both the research and application of the construction techniques for the project are described in the aspects of the foundation excavation and treatment, the construction method of the cast-in-site concrete box underdrain and the after curing technique for the concrete. At the same time, the key techniques, which plays a decisive role during the construction of the project, for the route selection, design and construction of the construction road in the desert zone are expatiated as well. On the whole, the key techniques presented herein can be taken as the references for the other similar projects.
