鋼波紋涵管(guan)路堤法的工(gong)藝流程為：施工(gong)前準(zhun)(zhun)備—施工(gong)放樣—設置圍堰—排水(shui)(shui)清淤—平(ping)整(zheng)場(chang)(chang)地—檢(jian)測(ce)(ce)(ce)壓實度(du)、含水(shui)(shui)量(liang)(liang)(liang)等—水(shui)(shui)準(zhun)(zhun)測(ce)(ce)(ce)量(liang)(liang)(liang)—平(ping)整(zheng)場(chang)(chang)地—基礎分層(ceng)回(hui)填—檢(jian)測(ce)(ce)(ce)壓實度(du)含水(shui)(shui)量(liang)(liang)(liang)等—水(shui)(shui)準(zhun)(zhun)測(ce)(ce)(ce)量(liang)(liang)(liang)—平(ping)整(zheng)場(chang)(chang)地—施工(gong)方樣—拼裝管(guan)節(jie)—檢(jian)測(ce)(ce)(ce)密水(shui)(shui)情況及管(guan)底縱坡—檢(jian)測(ce)(ce)(ce)并(bing)補救防腐(fu)涂(tu)層(ceng)—涵管(guan)就位——兩(liang)側分層(ceng)回(hui)填—檢(jian)測(ce)(ce)(ce)壓實度(du)、含水(shui)(shui)量(liang)(liang)(liang)等—進出口(kou)處(chu)理。

鋼波紋涵管在(zai)2019年的工作(zuo)重點在(zai)哪里？

涵洞(dong)施工前應(ying)(ying)根據具體情況修筑相應(ying)(ying)長度的施工便道，并合(he)理組(zu)織(zhi)過往車輛。涵洞(dong)施工前必(bi)須(xu)對(dui)到現場(chang)的涵管節及其附屬配件進行檢(jian)測，一(yi)方(fang)面(mian)(mian)檢(jian)測其結構尺寸是否滿(man)足要(yao)求，另(ling)一(yi)方(fang)面(mian)(mian)檢(jian)測其表面(mian)(mian)防(fang)腐(fu)(fu)是否達到要(yao)求；必(bi)要(yao)時須(xu)在鍍鋅涂層表面(mian)(mian)在增涂瀝(li)青或(huo)其他防(fang)腐(fu)(fu)材(cai)料。

拼接波紋管涵(han)怎樣(yang)施(shi)工？

鋼波紋涵管反開槽回(hui)填法涵洞(dong)施(shi)工前(qian)(qian)備齊所(suo)需材料。涵洞(dong)施(shi)工前(qian)(qian)應準(zhun)備涵洞(dong)施(shi)工過程(cheng)中(zhong)試驗。檢測儀器和設備，落實試驗人員。金屬(shu)波(bo)紋涵管路堤(di)法涵洞(dong)施(shi)工前(qian)(qian)施(shi)工單位(wei)需要通知監理(li)及相關人員到場，并按程(cheng)序辦(ban)理(li)施(shi)工前(qian)(qian)的(de)手續。

涵管(guan)施工(gong)前(qian)應(ying)設(she)一(yi)名(ming)管(guan)道(dao)安裝指揮人員，負責指揮吊裝及(ji)施工(gong)人員的現(xian)場操作；設(she)置1~2名(ming)技(ji)術人員負責放線。涵管(guan)安置等控(kong)制關(guan)(guan)鍵技(ji)術；同(tong)時配置適當的輔助人員。涵洞施工(gong)前(qian)應(ying)備齊所需的機(ji)械設(she)備及(ji)相(xiang)關(guan)(guan)工(gong)具，反開槽回(hui)填法(fa)的工(gong)藝(yi)流程為。

鋼波(bo)紋涵管洞(dong)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝流程可分為路(lu)堤法和反開槽回填法，由(you)于后者(zhe)涵洞(dong)的(de)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)多在(zai)路(lu)基(ji)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)結(jie)束后和改建涵洞(dong)，所以不(bu)影響路(lu)基(ji)施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)整體(ti)進度，一(yi)般后者(zhe)較為多見。盡管在(zai)外力上(shang)二者(zhe)存(cun)在(zai)一(yi)定的(de)差異(yi)，但施(shi)(shi)(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝相差不(bu)大。下(xia)面分別予(yu)以敘述。
