第二节 加固机理
二、水泥粉喷体喷射深层搅 拌加固机理
采用水泥粉体、生石灰和消石灰等 粉体固化剂，粉体固化剂与原状土 搅拌混合后，使地基土和固化剂发 生一系列物理化学反应，生成稳定 的水泥土或石灰土。水泥粉体加固 原理同水泥浆体。

三、石灰粉喷体喷射深层搅 拌加固机理
壁滑动，深基坑开挖支护； ⑶加固道路、桥涵； ⑷作为地下防渗墙，阻止地下水渗透。
地基处理-深层搅拌法课件
适用条件
目前国内水泥土深层搅拌法主要用 于加固淤泥、淤泥质土、地基承载 力不大于120kPa的粘性土和粉土 等地基。 用于处理泥炭土和地下水具有侵 蚀性时，应通过试验确定。

(二)粘土颗粒与水泥水化物的作用
2.硬凝反应 在碱性环境下，溶液中析出大量的钙 离子，与二氧化硅或三氧化铝产生化学 反应，生成不溶于水的铝酸钙等结晶水 化物。在水中和空气中逐渐硬化，提高 水泥强度，使水泥具有足够的水稳定性。

第二节 加固机理
第一节 概述
干法常称为粉喷搅拌法
该工艺利用压缩空气通过固化材料供给机的特殊 装置，携带着粉体固化材料，经过高压软管和搅 拌轴输送到搅拌叶片的喷嘴喷出，借助搅拌叶片 旋转，在叶片的背面产生空隙，安装在叶片背面 的喷嘴将压缩空气连同粉体固化材料一起喷出， 喷出的混合气体在空隙中压力急剧降低，促使固 化材料就地粘附在旋转产生空隙的土中，旋转到 半周，另一搅拌叶片把土与粉体固化材料搅拌混 合在一起，同时，这只叶片背后的喷嘴将混合气 体喷出，这样周而复始地搅拌、喷射、提升，与 固化材料分离后的空气传递到搅拌轴的周围，上 升到地面释放。 地基处理-深层搅拌法课件
