大口径泥水平衡顶管进出洞技术措施

Large diameter slurry balance pipe jacking in and out hole technical measures

大口径泥水平衡顶管进出洞技术是顶管工程的关键工序之一,本文根据广州市西江引水工程—输水管线-干线(里和路至和顺立段)DN3600顶管段工程的施工实践,该顶管横穿环城高速路,埋深10米左右,采用封闭式泥水平衡顶管,通过制定的控制措施和预防措施,以及在施工中出现或者可能出现的问题,解决问题的方法及预防措施,通过三个来月的顶管施工发现,顶管机出洞、进洞的工序是关键工序,直接决定了顶管的成功或失败,本文阐述大口径泥水平衡顶管进出洞技术。

Large diameter slurry balance pipe jacking in hole of pipe jacking project technology is one of the key working procedure , This paper based on the xijiang water diversion project delivery pipe line - route and the way to smooth made section） Diameter pipeline construction 3,600 top practice, The pipe across the city highway, Buffed depth of 10 meters, Closed slurry balanced pipe jacking,Through the development of control and prevention measures, Issues that may arise and appear in the construction or, Problem - solving methods and prevention measures, Found via sangelai months of pipe jacking construc- tion, Pipe - jacking machine out of the cave, the entrance of the process are the key processes, directly determines the success or failure of pipe jackin,This article large diameter slurry balance this pipe jacking technology and hole.
