鋼(gang)波紋(wen)涵管路(lu)堤法的工(gong)藝(yi)流程為：施工(gong)前準備—施工(gong)放樣(yang)—設(she)置圍(wei)堰—排水(shui)清淤—平(ping)整場地(di)—檢測(ce)(ce)(ce)壓(ya)實(shi)度、含(han)水(shui)量(liang)(liang)(liang)等(deng)(deng)—水(shui)準測(ce)(ce)(ce)量(liang)(liang)(liang)—平(ping)整場地(di)—基礎分層(ceng)回填—檢測(ce)(ce)(ce)壓(ya)實(shi)度含(han)水(shui)量(liang)(liang)(liang)等(deng)(deng)—水(shui)準測(ce)(ce)(ce)量(liang)(liang)(liang)—平(ping)整場地(di)—施工(gong)方樣(yang)—拼裝管節(jie)—檢測(ce)(ce)(ce)密水(shui)情(qing)況(kuang)及管底縱坡(po)—檢測(ce)(ce)(ce)并補救防腐涂層(ceng)—涵管就位——兩(liang)側(ce)分層(ceng)回填—檢測(ce)(ce)(ce)壓(ya)實(shi)度、含(han)水(shui)量(liang)(liang)(liang)等(deng)(deng)—進(jin)出口(kou)處(chu)理。

鋼波紋涵管在2019年的工(gong)作(zuo)重點在哪里？

涵(han)洞(dong)施工前(qian)應根據(ju)具體(ti)情況修(xiu)筑相應長度的施工便道(dao)，并(bing)合理組織(zhi)過往車輛(liang)。涵(han)洞(dong)施工前(qian)必須對(dui)到現場(chang)的涵(han)管節及(ji)其(qi)(qi)附屬配件進行檢(jian)測，一(yi)方(fang)面檢(jian)測其(qi)(qi)結(jie)構尺寸是否(fou)滿(man)足(zu)要求(qiu)，另(ling)一(yi)方(fang)面檢(jian)測其(qi)(qi)表(biao)(biao)面防腐是否(fou)達到要求(qiu)；必要時(shi)須在鍍鋅涂(tu)層表(biao)(biao)面在增涂(tu)瀝青或(huo)其(qi)(qi)他防腐材料(liao)。

涵(han)管施工(gong)前(qian)應設一名(ming)管道安裝指揮人員(yuan)，負(fu)責指揮吊裝及施工(gong)人員(yuan)的現(xian)場(chang)操作；設置(zhi)1~2名(ming)技術(shu)人員(yuan)負(fu)責放(fang)線。涵(han)管安置(zhi)等控制關鍵技術(shu)；同時配(pei)置(zhi)適當(dang)的輔助人員(yuan)。涵(han)洞施工(gong)前(qian)應備齊所需的機(ji)械設備及相(xiang)關工(gong)具，反開槽(cao)回(hui)填法的工(gong)藝流(liu)程為。

鋼(gang)波紋涵(han)(han)管洞(dong)施(shi)(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)流程可(ke)分為(wei)路(lu)堤法和(he)反開(kai)槽回(hui)填法，由于后(hou)者涵(han)(han)洞(dong)的施(shi)(shi)工(gong)(gong)(gong)多在路(lu)基施(shi)(shi)工(gong)(gong)(gong)結束(shu)后(hou)和(he)改(gai)建(jian)涵(han)(han)洞(dong)，所以(yi)不影響路(lu)基施(shi)(shi)工(gong)(gong)(gong)整體進(jin)度，一(yi)般后(hou)者較為(wei)多見。盡管在外力(li)上二者存在一(yi)定的差(cha)異，但施(shi)(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)相(xiang)差(cha)不大。下(xia)面(mian)分別予(yu)以(yi)敘述。
