南水北调工程是继三峡工程、西气东输、西电东送之后的又一特大型工程,沿线结构物类型较多,涉及到许多渡槽建筑物,而渡槽基础大都采用钻孔灌注桩基础,而旋挖钻施工工艺是近年兴起的施工技术。现结合南水北调中线湍河渡槽工程浅析旋挖钻施工技术。为了确保旋挖钻施工质量达到设计要求,须制定采用合理的施工工艺或技术可保证灌注桩的施工质量和施工进度。
The South-to-North Water Diversion Project is another large-scale project following the Three Gorges Project, the West-East Gas Pipeline Project and the West-East Power Transmission Project. There are many types of structures along the route, involving many aqueduct structures. Most of the aqueduct foundations use bored pile foundation, Rotary drilling construction technology is the rise of construction technology in recent years. Analysis of Rotary Drilling Construction Technology in Combination with Turbulent Aqueduct Project in the Middle Route of South - to - North Water Diversion Project. In order to ensure the construction quality of rotary drilling reaches the design requirements, it is necessary to formulate a reasonable construction technology or technology to ensure the construction quality and construction progress of the piles.
