1粉喷桩工程概述粉喷桩是“粉体喷射搅拌桩”的简称,就是利用专用的喷粉搅拌钻机将水泥等粉体固化剂喷入软土地基中,并将软土与固化剂强制搅拌,利用固化剂与软土之间所产生的一系列物理化学反应,使软土结成具有一定强度的水泥桩体而形成复合地基的一种施工方法。胶州湾三河入海口岸线保护工程共需打设长度6~10m、直径500mm粉喷桩14548根。2主要工艺流程施工准备→测放桩位→钻机就位→钻进→离设计底标高
1 DJM Project Overview DJM is referred to as “powder jet mixing pile”, is the use of special powder mixing drill cement and other powder curing agent is injected into the soft soil foundation, and soft soil and curing Agent forced mixing, the use of curing agent and soft soil produced by a series of physical and chemical reactions, so that the formation of a certain degree of soft soil cement pile body and form a composite foundation of a construction method. Jiaozhou Bay Sanhe estuary shoreline protection projects need to set up a total length of 6 ~ 10m, diameter of 50048 spray pile 14548. 2 The main process Construction preparation → Piling → measuring position → drilling rig in place → drilling → design base height
