Laying a underground conduit system requires accurate records to be accessible in its maintenance and management in the future. Therefore, all the new fixed network companies should engage in building up conduit database systems to enhance their industrial competitiveness right from the beginnings of their construction.

地下管线若无准确的资料，易造成维修及管理之困扰，所以各新兴之固网业者，应趁建设之起步即著手於管线资料网路资料库系统之建立，以提升其产业竞争力。

And for the deep-buried pipe, the methods of surface reinforcement and strenghening the surrounding rock from the tunnel face are adopted, which have the effective action on controlling the surface settlement. These measures ensure the safety of gas pipe, and have importat reference value.

对于埋深较浅段，采取了明挖加固法，对于埋深相对较大段，采用地表加固和洞内加固相结合的方法，有效控制了地表和管线的沉降量，确保了燃气管线的安全，对类似工程有一定的参考价值。

When the pipeline produces condensate, trap enclosure cooling, the trap begins to drain; in the superheated steam pipe on the absence of condensate production, trap does not open, the work of high quality.

当管线截止阀产生凝结水，疏水阀外壳降温，疏水阀开始排水；在过热蒸汽管线上如果没有凝结水产生，疏水阀不会开启，工作质量高。
