偏心振捣搭设钢架平台的应用

Application of Eccentric Vibrating Erection of Steel Bracket Platform

随着我国水利基础设施建设的快速发展,钻孔灌注桩作为一种基础处理形式被广泛地应用于水利堤防、沿海围垦、内河闸站及其他工程领域。但由于影响灌注桩施工的因素很多,所以对其施工过程每一环节都必须严格要求,特别是针对某些无法直接陆地施工的特殊地段,需要搭设钢架平台代替陆地施工。结合水上钻孔灌注桩的施工特点,利用偏心振捣器的偏心振捣原理,用手动葫芦辅助下沉配合施工搭设钢架平台,代替了以往船上挖机压打钢管搭设钢架平台的施工,加快了钢架平台的搭设进度,节省了成本,减少了安全隐患。

Bored grouting pile , as basic treatment form , is widely used in water conservancy dike , coastal reclamation , inner river gate station and other engineering fields with rapid development of China ’ s water conservancy infrastructure construction .However , every aspect of construction process thereof must be strictly required since there are many factors affecting grouting pile construction .Steel bracket platform should be erected for replacing land construction especially aiming at some special locations incapable of direct land construction .Construction characteristics of water bored grouting pile are considered , and eccentric vibrating principle of eccentric vibrator is utilized .Using manual hoist assisting sinking to cooperate with the construction erection of steel bracket platform , thereby replacing previous construction of pressing steel pipes and erecting steel bracket platform by digging machine on the vessel , accelerating erection progress of steel bracket platform, saving cost, and reducing safety hidden danger .
