Large-diameter cast-in-place pile bottom soft soil layer reinforcing system and method
The invention discloses a system and method for reinforcing a soft soil layer at the pile bottom of a large-diameter cast-in-place pile, solves the problem that in the prior art, the mode for treating the soft soil layer is complex, and has the beneficial effects that operation is convenient, and the construction period is shortened, and according to the specific scheme, the system for reinforcing the soft soil layer at the pile bottom of the large-diameter cast-in-place pile comprises a spraying pipe; the spray pipe can be connected with a drilling machine, and the spray pipe can be inserted into a central grouting hole of the large-diameter cast-in-place pile and extends into a pile bottom soft soil layer at the bottom of the large-diameter cast-in-place pile; a first nozzle, a second nozzle and a third nozzle are sequentially arranged at the top of the spray pipe from top to bottom, the first nozzle is connected with a slurry supply component, the second nozzle is connected with an air supply component, the third nozzle is connected with a water supply component, and the second nozzle and the third nozzle are annular. The second nozzle is inserted into the hollow part of the third nozzle which is fixedly connected with the spray pipe body.
本发明公开了一种大直径灌注桩桩底软弱土层加固系统及方法，解决了现有技术中处理软弱土层的方式较为复杂的问题，具有方便操作、节约工期的有益效果，具体方案如下：一种大直径灌注桩桩底软弱土层加固系统，包括喷管，喷管可与钻机连接，喷管可插入至大直径灌注桩的中心注浆孔内，并伸入至大直径灌注桩底部的桩底软弱土层中；喷管顶部从上到下依次设置第一喷嘴、第二喷嘴和第三喷嘴，第一喷嘴与浆液供给部件连接，第二喷嘴与供气部件连接，第三喷嘴与供水部件连接，第二喷嘴和第三喷嘴均为环形，第一喷嘴插入第二喷嘴的中空处，第二喷嘴插入第三喷嘴的中空处，第三喷嘴与喷管本体固连。
