摘要： 介绍了人工挖孔灌注桩孔内地下水上升速度较快(大于6mm/min)稳定水深不大情况下,桩基采用具有陆上砼和水下砼施工特点的浇注方法;通过半幅整体现浇施工解决I型梁预应力张拉由于横向刚度不够产生横向挠曲变形的问题;及大面积砼墙身分层施工时,因施工缝漏浆产生的水平带状蜂窝麻面和滴"眼泪"的处理方法.

关键词: 施工监理, 挖孔灌注桩, I型梁, 工程质量

Abstract: Based on the characteristics of concreting in air and in water, the paper discusses the rising seepage velocity (>6 mm/min)in hole while pile excavated in place is built in highway construction.The half range-concrete method is adopled to settle the transversal deflection in I-shaped beam with less transversal rigidity.Some measures are taken in the layered conerete of massive wall and the strip honeycomb with rough surface due to cement mortar seeped in construction joint.

Key words: construction supenision, pile excavated in place, I-shaped beam, quality
