| 摘 要： | 南水北调中线工程，各施工区地形陡峻，可供布置施工场地的缓坡地较少。从实践结果来看，选用龙门吊式皮带布料机进行混凝土入仓施工，可保证混凝土的入仓速度与技术要求；采取行走钢模台车的循环施工，既节约了投资，缩短了工期，同时又保证了预应力混凝土的外观质量。本工程的成功实施，为其他类似的大型倒虹吸工程施工提供了具有借鉴性的经验。

| Abstract: | The terrain of construction area of south-to-north water diversion midline project is precipitous, gentle sloping field adapting to dispose construction field is less. According to practice, adopting gantry crane type belt spreader to process the concrete pouring construction can guarantee the pouring velocity and technology demand, and adopting circulatory construction of walking steel trolley can not only save the cost, shorten the construction period, but aslo guarantee the appearance quality of prestressed concrete synchronously. |
