Construction Technology of Cast-in-Place Pile of a Bridge

介绍了某大桥灌注桩施工方法,控制好泥浆比重、混凝土的坍落度与和易性是保证顺利灌注混凝土的重要因素。重点对成孔、清孔、泵送混凝土的配制和灌注以及灌注中常见问题的处理等施工关键工艺作了论述。

Construction technology of cast-in-place pile of a bridge is introduced. Keeping a good balance of mud weight, slump and workability of concrete are the important factors to ensure per- fusing concrete smoothly. Focus is not only put on pore-forming, pore-clearing and the colloca- tion and perfusion of pumped concrete, but also solutions to common problems in perfusion. on the critical process of construction, such as
