随着我国公路工程建设的发展,在山岭重丘区修建桥梁越来越多,但由于受地形条件限,桥梁桩基机械成孔困难,但根据工程需要,在地质条件允许的情况下,可采用人工挖孔方法进行基础施工。本文结合桥梁施工工作经验,介绍了在桥梁桩基施工中采用挖孔桩施工的方法,从施工技术等方面进行了论述,希望对从事桥梁施工的工作者有一定的参考作用。
With the development of highway construction in our country, more and more bridges are built in the mountain heavy hill area. However, due to limited topographic conditions, it is difficult for the bridge pile foundation machinery to form holes, but according to the project requirements, under the condition of geological conditions, Using manual hole digging method for basic construction. Based on the experience of bridge construction, this paper introduces the method of digging hole piles in the construction of bridge pile foundation, discusses the construction techniques and so on. It is hoped that it will be helpful to the workers engaged in bridge construction.
