摘要
顶管施工是主要非开挖技术之一。其施工方法不断改进,已出现许多新的施工工艺,地下对接技术就是其中之一。以白龙港南线输送干线SST1.2标过江管工程W3号井顶管对接为例,该顶管对接采用2台顶管机夹角为120°的斜交对接,不同于以往顶管直面(180°)或垂直(90°)对接的形式,是顶管对接领域的一项技术创新。
Pipe jacking construction is one of the main trenchless technologies.These construction methods continue to be improved,and there have been many new construction technologies,among which underground joint technology is the one.Taking crossriver pipeline project No.W3 well pipe jacking joint of Bid SST1.2 of Bailonggang South Line as an example,the pipe jacking with two jacking machine angle of 120° bevel joint,being different from the joint types of previous pipe jacking(180°) or vertical(90°),which is a technique innovation in the field of pipe jacking joint.
