摘要
钻孔灌注桩具有低噪音、小震动、无挤土,能穿越各种复杂地层和形成较大的单桩承载力,在市政桥梁等工程中得到广泛应用。本文针对南平西城大桥复杂的地质情况,对成孔的钻机设备进行比较分析,最终确定采用旋挖钻机方法进行钻进施工,并对施工中易发生的质量问题提出有效的控制措施,尽可能防止质量事故发生。
Bored pile with low noise, small vibration, no soil compaction, through a variety of complex formation and the formation of large bearing capacity of single pile, in municipal bridge is widely used in engineering. This article in view of Nanping West Bridge in complex geological condition, the hole drilling machine to carry on the comparative analysis, it was determined to use the rotary drilling rig for drilling construction, and the construction quality problems easily occurring in effective control measures, prevent as far as possible quality accidents.
