Deep cement mixing pile long-drilling multi-layer fin rapid stirring and spraying construction method
The invention provides a deep cement mixing pile long-drilling multi-layer fin rapid stirring and spraying construction method. The method comprises the following steps that S100, a site is cleaned, and cement mixing equipment and a drill bit are installed; s200, sequentially completing the work arrangement of cementing material entering the field, the installation of automatic stirring equipment and guniting (powder) equipment in place, and carrying out a field test; s300, the rotating speed, the drilling lifting speed, the drilling lifting speed and the guniting (powder) pressure are set; s400, surveying and setting-out are carried out at the construction point, and drilling is started after surveying and setting-out are completed and a drilling machine is in place; s500, re-stirring and re-spraying are conducted on the original position of the pile bottom for 60 s; and S600, after re-stirring and re-spraying of the pile bottom are completed, the drill starts to be lifted upwards from the pile bottom, and S700, stirring equipment is moved to the next pile position to continue stirring operation. By means of the deep cement mixing pile long-drilling multi-layer wing piece rapid stirring and spraying construction method, 50% of working procedures can be reduced, and the work efficiency can be improved by 60% or above.
本发明提供了一种深层水泥搅拌桩长钻多层翼片快速搅喷施工方法，包括如下步骤：S100、场地清理，安装水泥搅拌设备和钻头；S200、依次完成胶凝材料进场工作安排，自动化搅拌设备及喷浆(粉)设备安装就位，开展现场试验；S300、设置转速、下钻提速度和提钻速度以及喷浆(粉)压力；S400、在施工点进行测量放样，待测量放样完成以及钻机就位后，开始下钻；S500、在桩底原位置复搅复喷60s；S600、桩底实现复搅复喷完成后，开始从桩底向上提钻，S700、搅拌设备移至到下个桩位上继续开展搅拌作业。应用上述深层水泥搅拌桩长钻多层翼片快速搅喷施工方法，可以能够减少50％工序，提高工效60％以上。
