| 摘 要： | 导向孔的施工是非开挖施工的关键，它决定着非开挖的成功与否。通过在长沙市繁华路段复杂地下管网、管线的非开挖施工，本文探讨了在复杂地层(卵砾层)导向孔的施工工艺。同时，在地层稳定的条件下，用人工扩大了钻孔，形成了微断面隧道，为微断面隧道在非开挖领域的应用开辟了新的思路。

| Abstract: | The oriented hole construction technique is key in no dig engineering,it decides the success or defeated of no dig engineering.The operations were conducted for drilling through the busyness road,which has many various pipes underground in Changsha,and laying pipelines in no dig technique.In this paper,we discuss the working procedure in no dig engineering in complex area.Meanwhile,we extend the drilling hole and shaping micro tunnel in stabilization,the new idea that is the application of micro tunnel in no dig may be expanding. |

| Keywords: | no dig guide hole complex area micro tunnel |
