Single-shaft bidirectional stirring device and cement stirring pile construction method
The invention relates to foundation treatment engineering, in particular to a single-shaft bidirectional stirring device and a cement stirring pile construction method. The single-shaft bidirectional stirring device can force a moving pipe to drive an inner nozzle to be separated from an outer nozzle in a normal state through moving driving, a connecting channel between the inner nozzle and the outer nozzle is disconnected, and thus the problem that idle sandy soil enters the inner nozzle can be effectively solved, and the unblocked degree of the slurry outlet end of a pipeline during slurry spraying or water spraying operation is improved; meanwhile, an extension ring arranged on the inner nozzle can effectively shield a gap between the outer nozzle and the inner nozzle, slurry entering the gap is reduced, the friction resistance between the moving pipe and a stirring pipe is reduced, and the moving efficiency between the moving pipe and the stirring pipe is improved; the moving pipe is provided with a shielding part capable of shielding and blocking the outer nozzle so that the risk that the sandy soil enters the stirring pipe through the outer nozzle can be further reduced; and by means of the single-shaft bidirectional stirring device, the risk that the pipeline is blocked by the sandy soil in the pile position tunneling process during cement stirring pile construction can be reduced, and smooth proceeding of the guniting lifting step is facilitated.
本申请涉及地基处理工程，尤其涉及的是一种单轴双向搅拌装置及水泥搅拌桩施工方法。单轴双向搅拌装置通过移动驱动可迫使移动管常态带动内喷口脱离外喷口，断开内喷口与外喷口的连接通道，可有效改善闲置状态下沙土进入内喷口的问题发生，提高喷浆或喷水作业时管道出浆端的畅通程度；同时内喷口设置的延伸圈可有效遮挡外喷口与内喷口之间的间隙，减少浆液进入该间隙，降低移动管与搅拌管之间的摩擦阻力，提高二者之间的移动效率；且移动管具有可遮挡堵塞外喷口的遮挡部，可进一步减少沙土通过外喷口进入搅拌管的风险。使用上述的单轴双向搅拌装置可为水泥搅拌桩施工过程的桩位掘进过程中减少沙土堵塞管道的风险，便于喷浆提升步骤的顺利进行。
