摘要
钻孔灌注桩的质量控制是一项技术性要求比较高的工作。上海长江隧桥B5标主通航孔变截面钻孔桩直径大,桩长长,质量控制困难。结合现场的实际情况,对超长大直径群桩施工中的监理措施做以介绍。指出了监理控制要点及具体施工要求。
The quality control of bored pile requires high technology. Bored piles at B5 bid main navigable hole of Shanghai Yangtze River Tunnel Bridge have variable section with large diameter and length. It is difficult to control the quality of bored piles. Based on actual situation, measurements for bored piles group supervision are introduced during construction, as well as corresponding control points and construction requirements.
