地铁沟槽式空调水管连接施工

Subway Trench Type Air Conditioning Water Pipe Connection Construction

当前城市地铁机电工程中,空调水管大多采用焊接及螺纹连接,其中冷水机房一般采用无缝钢管焊接连接,施工过程复杂,且焊接过程中产生大量的有害气体,并且大量的焊接作业,现场安全问题难以控制。为保证施工作业人员的职业健康以及现场安全作业,急需一种新的施工工艺,沟槽式连接方式作为一个普遍应用的连接方式,应用于地铁空调水系统可以有效地解决上述问题。

At present,in urban subway mechanical and electrical engineering,air conditioning pipes are mostly welded and threaded,and the cold water room is generally seamless steel pipe welding connection,the construction process is complex,and a large number of harmful gases are produced in the welding process,and a large number of welding operations,the site safety problems are difficult to control.In order to ensure the occupational health of construction workers and the safety operation on site,a new construction technology is urgently needed.As a widely used connection mode,the trench connection method can effectively solve the above problems in the subway air conditioning water system.
