鋼波紋(wen)涵管在2019年(nian)的工(gong)作(zuo)重點在哪里？

涵(han)洞(dong)施(shi)工前(qian)應(ying)根據具體情(qing)況修筑相(xiang)應(ying)長度的(de)施(shi)工便道(dao)，并合理組(zu)織過往車輛。涵(han)洞(dong)施(shi)工前(qian)必(bi)須對(dui)到現場的(de)涵(han)管節及其附屬配件(jian)進行檢測，一(yi)方面(mian)檢測其結構尺寸是否滿足要(yao)求，另一(yi)方面(mian)檢測其表面(mian)防腐是否達到要(yao)求；必(bi)要(yao)時須在鍍鋅涂層表面(mian)在增涂瀝青或其他防腐材料。

鋼波紋涵管反開槽回填(tian)法(fa)(fa)涵(han)洞(dong)施工(gong)(gong)(gong)前備(bei)齊(qi)所需(xu)材料。涵(han)洞(dong)施工(gong)(gong)(gong)前應(ying)準(zhun)備(bei)涵(han)洞(dong)施工(gong)(gong)(gong)過程(cheng)中試驗。檢測儀器和(he)設備(bei)，落實試驗人(ren)員(yuan)。金屬波紋涵(han)管路堤法(fa)(fa)涵(han)洞(dong)施工(gong)(gong)(gong)前施工(gong)(gong)(gong)單位(wei)需(xu)要(yao)通知監理(li)及相關人(ren)員(yuan)到場，并按程(cheng)序辦理(li)施工(gong)(gong)(gong)前的(de)手續。

涵管(guan)(guan)施(shi)工(gong)前應設一名管(guan)(guan)道安(an)裝(zhuang)指(zhi)揮人員(yuan)，負責(ze)指(zhi)揮吊裝(zhuang)及施(shi)工(gong)人員(yuan)的(de)(de)現場操作；設置(zhi)1~2名技術(shu)人員(yuan)負責(ze)放線(xian)。涵管(guan)(guan)安(an)置(zhi)等控制關鍵技術(shu)；同時配置(zhi)適當的(de)(de)輔助人員(yuan)。涵洞施(shi)工(gong)前應備齊所需的(de)(de)機械設備及相關工(gong)具，反開槽回填法的(de)(de)工(gong)藝(yi)流程為。

鋼波紋涵(han)(han)管(guan)洞(dong)施工(gong)(gong)工(gong)(gong)藝流程(cheng)可分(fen)為路(lu)堤法(fa)和反開槽回(hui)填法(fa)，由于后(hou)(hou)者涵(han)(han)洞(dong)的施工(gong)(gong)多在(zai)路(lu)基施工(gong)(gong)結束后(hou)(hou)和改建涵(han)(han)洞(dong)，所(suo)以不影響路(lu)基施工(gong)(gong)整體進(jin)度，一(yi)般后(hou)(hou)者較為多見。盡(jin)管(guan)在(zai)外力上二者存(cun)在(zai)一(yi)定(ding)的差(cha)異，但施工(gong)(gong)工(gong)(gong)藝相差(cha)不大。下面分(fen)別予以敘述。
