化工厂富水破碎带中人工挖孔桩的施工探讨

Rich in a Chemical Plant in the Water with Broken Hana-dug Pile of Comstruction

针对在某化工厂由富水断层破碎带和淤泥质软土组成的复杂地基中施工人工挖孔桩时,所遇到的孔壁坍塌、流砂(土)、掉块及有害气体伤害等工程问题,采用了桩孔超前疏水、钢筋栅栏、钢模护筒、井底灌浆护壁及鼓风换气等处理措施,取得了较好的治理效果,确保了桩基工程的顺利完成。

For a certain chemical from water - rich fault broken mud and soft soil composition of the compolexity of the foundation construction of artificial hole pile, the hole encountered by the collapse of the wall,the flow of sand（soil） ,and block out harmful gases Injury , and other engineering problems , using a pile KONG ahead of hydrophobic, steel fencing , steel casing , filling the bottom of the well wall and the blast , such as ventilators to deal with measures to achieve good results , to ensure that the foundation works smoothly.
