鋼波紋(wen)涵管路堤法的工藝流程為：施工前準備—施工放樣—設置圍堰—排水(shui)(shui)清淤(yu)—平(ping)整場地(di)(di)—檢(jian)測(ce)壓(ya)實(shi)(shi)度、含水(shui)(shui)量(liang)等(deng)—水(shui)(shui)準測(ce)量(liang)—平(ping)整場地(di)(di)—基礎(chu)分層(ceng)回填(tian)—檢(jian)測(ce)壓(ya)實(shi)(shi)度含水(shui)(shui)量(liang)等(deng)—水(shui)(shui)準測(ce)量(liang)—平(ping)整場地(di)(di)—施工方樣—拼裝(zhuang)管節(jie)—檢(jian)測(ce)密水(shui)(shui)情況及(ji)管底(di)縱(zong)坡—檢(jian)測(ce)并補救防腐涂(tu)層(ceng)—涵管就位——兩側(ce)分層(ceng)回填(tian)—檢(jian)測(ce)壓(ya)實(shi)(shi)度、含水(shui)(shui)量(liang)等(deng)—進出口處理。

鋼波紋(wen)涵管在2019年的工(gong)作重點(dian)在哪(na)里？

涵洞施工(gong)前應(ying)(ying)根(gen)據具體(ti)情(qing)況(kuang)修筑(zhu)相應(ying)(ying)長(chang)度的(de)施工(gong)便道，并合理組織過往(wang)車輛。涵洞施工(gong)前必須對到(dao)現場的(de)涵管節及其(qi)附屬配件進行檢測，一(yi)方面(mian)(mian)檢測其(qi)結構尺寸是否滿足要求，另一(yi)方面(mian)(mian)檢測其(qi)表面(mian)(mian)防腐(fu)是否達(da)到(dao)要求；必要時(shi)須在鍍鋅涂層表面(mian)(mian)在增涂瀝青或其(qi)他防腐(fu)材料(liao)。

拼接波紋(wen)管(guan)涵怎樣施工？

鋼波紋涵管反開槽回填(tian)法涵(han)洞施工(gong)前(qian)備齊所需材料。涵(han)洞施工(gong)前(qian)應(ying)準(zhun)備涵(han)洞施工(gong)過程中試(shi)驗。檢測儀(yi)器和(he)設備，落實試(shi)驗人(ren)員(yuan)。金(jin)屬波紋涵(han)管路堤法涵(han)洞施工(gong)前(qian)施工(gong)單位需要通知(zhi)監理(li)及相(xiang)關人(ren)員(yuan)到場(chang)，并按程序辦(ban)理(li)施工(gong)前(qian)的手續(xu)。

涵管施(shi)工(gong)前應設一名(ming)管道安裝指(zhi)揮人(ren)(ren)員(yuan)，負責指(zhi)揮吊裝及施(shi)工(gong)人(ren)(ren)員(yuan)的現場操作；設置1~2名(ming)技(ji)術人(ren)(ren)員(yuan)負責放線(xian)。涵管安置等控(kong)制關鍵技(ji)術；同時配置適(shi)當的輔(fu)助(zhu)人(ren)(ren)員(yuan)。涵洞(dong)施(shi)工(gong)前應備齊所需的機械設備及相關工(gong)具，反開槽回(hui)填法的工(gong)藝流程為。

鋼波(bo)紋涵(han)管洞(dong)(dong)施(shi)工(gong)(gong)工(gong)(gong)藝流程可(ke)分為路(lu)堤法(fa)和反開(kai)槽回填法(fa)，由于(yu)后者(zhe)涵(han)洞(dong)(dong)的施(shi)工(gong)(gong)多(duo)(duo)在路(lu)基施(shi)工(gong)(gong)結束后和改建涵(han)洞(dong)(dong)，所以不影響路(lu)基施(shi)工(gong)(gong)整體進(jin)度，一(yi)般后者(zhe)較為多(duo)(duo)見。盡管在外力(li)上(shang)二(er)者(zhe)存(cun)在一(yi)定的差異，但施(shi)工(gong)(gong)工(gong)(gong)藝相差不大。下(xia)面分別予以敘(xu)述。
