桩基础工程中,灌注桩正越来越多地应用于工程中。灌注桩的施工是一项技术十分强的施工技术,又是属于隐蔽工程。近年来泥浆护壁钻孔灌注桩工程单桩灌注量有的已高达到400多立方混凝土,在施工过程中,特别是灌注施工,施工中如发生质量问题将产生严重的后果和巨大经济损失。本文将从水下灌注施工中易出现的质量问题,谈一谈如何进行控制和避免。 Pile foundation engineering, filling pile is more and more used in engineering. Pouring pile construction is a very technical construction technology, but also belong to the hidden project. In recent years, mud perfusion bored piles of concrete perforated pile capacity has reached as high as more than 400 cubic meters of concrete in the construction process, especially in the pouring construction, construction quality problems such as quality problems will have serious consequences and great economic losses. This article will be from underwater filling construction prone to quality problems, talk about how to control and avoid.
