超厚流塑状冲填土地层粉喷桩地基处理技术

Foundation Treatment Technology of Dry Jet Pile Foundation in Super-thick Flow

粉喷桩施工技术就是粉体喷射搅拌桩施工技术,通过专用的喷粉搅拌钻机来把水泥等粉体固化剂向软土地基进行喷射的方法,并强制搅拌软土与固化剂,通过固化剂与软土在一定范围内出现的一系列物理化学反应,让软土能够结成相应强度的水泥桩体而出现复合地基的优势方法。

The construction technology of powder injection pile is the construction technology of powder jet mixing pile. It is a method of spraying cement and other powder curing agent to soft soil foundation by special powder mixing and drilling rig, and forced mixing soft soil and curing agent, through the curing agent and soft soil in a certain range of physical and chemical reactions, so that soft soil can form the corresponding strength of the cement pile and the advantages of composite foundation method.
