Construction Technology of Shield Tunneling Curve Start
Subway construction is mostly carried out in densely populated and built-up areas,with limited construction conditions.When designing subway lines,it is common to choose to start and receive on curves,which can easily cause the shield tunneling in and out of the tunnel structure to exceed the limit,water inrush or collapse at the tunnel entrance.In order to prevent such incidents from occurring and complete the initiation and reception on the curve with quality and safety,this shield tunneling curve initiation construction technology is often applied in shield tunneling construction.Among the 9 shield tunneling machines of Shenzhen Metro Line 7 Bid 7306,5 of them started on the curve and achieved good technical and economic results,gaining a good social reputation.
