摘要
在目前长输管道施工中,很多工序仍旧沿用传统的施工方法,机械化程度不高,施工效率低;同时受各种新材料、新工艺和特殊环境的影响,传统施工方法无法满足施工技术要求,因此需要采用先进的管道机械化施工技术和装备,以提高施工效率和降低施工成本。首先简要介绍了目前长输管道的施工现状,而后较为详细地论述了改进管道机械化施工设备及方法的建议,包括管沟开挖、管口测量、管口组对、管道预热、管道焊接、管道连头、管道防腐、沟底平整等方面,介绍了机械化装备的研究、使用原理和应用情况。
In current long distance pipeline construction,many traditional construction methods do not satisfy technical re-quirement. This paper discusses improvement suggestions on mechanized construction equipment and methods for longdistance pipeline,including ditching,pipe end measurement,pipes aligning,pipe preheating,welding,field joint,an-ticorrosion,ditch bottom leveling,etc.,also introduces the research,application principle and effects of mechanizedconstruction equipment.
