鋼波紋(wen)涵管路堤法的工藝(yi)流程(cheng)為(wei)：施(shi)工前準(zhun)備—施(shi)工放樣(yang)—設(she)置圍堰—排水(shui)(shui)清淤—平整(zheng)(zheng)場(chang)地(di)—檢測壓(ya)實(shi)度、含(han)(han)水(shui)(shui)量等—水(shui)(shui)準(zhun)測量—平整(zheng)(zheng)場(chang)地(di)—基(ji)礎分(fen)層回填—檢測壓(ya)實(shi)度含(han)(han)水(shui)(shui)量等—水(shui)(shui)準(zhun)測量—平整(zheng)(zheng)場(chang)地(di)—施(shi)工方樣(yang)—拼裝(zhuang)管節—檢測密水(shui)(shui)情況及管底縱坡—檢測并(bing)補救(jiu)防腐涂層—涵管就位——兩側分(fen)層回填—檢測壓(ya)實(shi)度、含(han)(han)水(shui)(shui)量等—進出口(kou)處(chu)理。

鋼波紋涵管(guan)在2019年的工作重(zhong)點在哪里？

涵(han)洞(dong)施工前(qian)應根據具體情況修(xiu)筑相(xiang)應長度的(de)施工便(bian)道，并合理組(zu)織(zhi)過往車(che)輛。涵(han)洞(dong)施工前(qian)必須對到現場的(de)涵(han)管節及其(qi)(qi)附屬配件(jian)進行檢測，一方面(mian)檢測其(qi)(qi)結構(gou)尺寸是(shi)否滿足要(yao)求，另一方面(mian)檢測其(qi)(qi)表(biao)面(mian)防(fang)腐(fu)是(shi)否達(da)到要(yao)求；必要(yao)時須在鍍鋅(xin)涂層(ceng)表(biao)面(mian)在增涂瀝青或其(qi)(qi)他(ta)防(fang)腐(fu)材料。

拼接波紋管涵(han)怎樣施工？

鋼波紋涵管反開槽(cao)回填(tian)法涵(han)洞施工(gong)前備齊所需材料。涵(han)洞施工(gong)前應準備涵(han)洞施工(gong)過(guo)程(cheng)中(zhong)試驗(yan)。檢測(ce)儀器和設備，落(luo)實(shi)試驗(yan)人(ren)(ren)員。金屬波紋涵(han)管路堤法涵(han)洞施工(gong)前施工(gong)單(dan)位需要通知(zhi)監理及相關人(ren)(ren)員到場，并按程(cheng)序辦理施工(gong)前的手續。

涵管(guan)施(shi)工(gong)前(qian)應設一名管(guan)道安裝(zhuang)指揮(hui)人(ren)員，負責(ze)指揮(hui)吊裝(zhuang)及(ji)施(shi)工(gong)人(ren)員的現場操(cao)作；設置(zhi)(zhi)1~2名技術(shu)人(ren)員負責(ze)放線。涵管(guan)安置(zhi)(zhi)等控制(zhi)關鍵技術(shu)；同(tong)時(shi)配(pei)置(zhi)(zhi)適當(dang)的輔助人(ren)員。涵洞施(shi)工(gong)前(qian)應備齊(qi)所需的機(ji)械(xie)設備及(ji)相關工(gong)具(ju)，反開槽(cao)回填法的工(gong)藝流(liu)程為。

鋼波紋涵(han)管洞施(shi)(shi)(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝流程可分為(wei)路堤法(fa)和(he)反開(kai)槽回填法(fa)，由于后者涵(han)洞的施(shi)(shi)(shi)工(gong)(gong)(gong)多在路基施(shi)(shi)(shi)工(gong)(gong)(gong)結束后和(he)改建(jian)涵(han)洞，所以(yi)不影(ying)響路基施(shi)(shi)(shi)工(gong)(gong)(gong)整(zheng)體進度，一般后者較為(wei)多見。盡管在外力上二者存(cun)在一定的差(cha)異(yi)，但施(shi)(shi)(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝相差(cha)不大。下面分別予以(yi)敘述。
