Multi-channel powder spraying mixing pile drilling machine equipment and construction method
The invention relates to the technical field of construction drilling machine equipment, in particular to multi-channel powder spraying mixing pile drilling machine equipment and a construction method.The multi-channel powder spraying mixing pile drilling machine equipment comprises a drilling machine body, a feeding background and a control module, and the control module monitors and controls all electric control switches, all sensors and instruments in real time; high-pressure gas and curing agent powder can be continuously, uniformly and quantitatively supplied to the gas pipeline of the drilling machine. Gas-solid two-phase mixed compressed fluid and high-pressure airflow enter a focusing area at the bottom of the multi-layer mutual-shearing stirring drill bit through a gas material channel and an airflow channel of the drilling tool, and the two high-pressure fluids become more uniform after being reflected, mixed and gasified in the focusing area. High-pressure spraying and stirring of a foundation soil body are achieved through stirring blades of the multi-layer mutual-shearing stirring drill bit and nozzles at the far end and the near end, and curing agent powder and undisturbed soil body are fully stirred and mixed to form the large-diameter high-quality powder spraying stirring pile under the staggered-layer shearing stirring effect of the multi-layer mutual-shearing stirring drill bit.
本发明涉及施工钻机装备技术领域，一种多通道粉喷搅拌桩钻机装备及施工方法，该装备包括钻机主体、供料后台和控制模块，控制模块通过对各电控开关、各传感器及仪器仪表的实时监测与控制，可实现对钻机的气料管道持续均匀定量供应高压气体和固化剂粉料。气固两相混合压缩流体和高压气流分别经过钻具的气料通道和气流通道进入多层互剪搅拌钻头底部的聚焦区域，两股高压流体在聚焦区域内部经反射混合气化后变得更为均匀，通过多层互剪搅拌钻头的搅拌叶片和远近两端的喷口实现对地基土体的高压喷射与搅拌，多层互剪搅拌钻头的错层剪切搅拌作用使固化剂粉料与原状土体充分搅拌混合形成大直径高质量粉喷搅拌桩。
