鋼波(bo)紋涵管路堤法的工(gong)藝流程為：施(shi)工(gong)前準(zhun)備—施(shi)工(gong)放樣—設(she)置圍堰—排水(shui)(shui)清(qing)淤—平(ping)整(zheng)場(chang)地—檢測(ce)壓實度(du)、含(han)水(shui)(shui)量等(deng)(deng)—水(shui)(shui)準(zhun)測(ce)量—平(ping)整(zheng)場(chang)地—基礎分層(ceng)回填(tian)—檢測(ce)壓實度(du)含(han)水(shui)(shui)量等(deng)(deng)—水(shui)(shui)準(zhun)測(ce)量—平(ping)整(zheng)場(chang)地—施(shi)工(gong)方樣—拼裝(zhuang)管節—檢測(ce)密水(shui)(shui)情況及管底縱坡—檢測(ce)并補救防腐涂層(ceng)—涵管就位(wei)——兩(liang)側(ce)分層(ceng)回填(tian)—檢測(ce)壓實度(du)、含(han)水(shui)(shui)量等(deng)(deng)—進出口處理。

鋼波紋涵管在2019年的工作重(zhong)點在哪(na)里？

涵洞施(shi)工(gong)(gong)(gong)前應根據具體(ti)情況修筑(zhu)相應長度的(de)施(shi)工(gong)(gong)(gong)便道(dao)，并合理(li)組織過往車(che)輛。涵洞施(shi)工(gong)(gong)(gong)前必須(xu)對到現場(chang)的(de)涵管節及其附屬配件進行檢測(ce)，一方面(mian)檢測(ce)其結構(gou)尺寸是(shi)否(fou)滿(man)足要求，另一方面(mian)檢測(ce)其表面(mian)防腐(fu)是(shi)否(fou)達(da)到要求；必要時須(xu)在(zai)鍍鋅涂層表面(mian)在(zai)增涂瀝(li)青或其他防腐(fu)材料。

鋼波紋涵管反開槽回填法涵(han)(han)(han)洞(dong)施工(gong)(gong)前(qian)(qian)備齊(qi)所(suo)需材料(liao)。涵(han)(han)(han)洞(dong)施工(gong)(gong)前(qian)(qian)應(ying)準備涵(han)(han)(han)洞(dong)施工(gong)(gong)過(guo)程中試驗。檢測(ce)儀(yi)器和(he)設備，落實試驗人員。金屬波紋涵(han)(han)(han)管(guan)路堤法涵(han)(han)(han)洞(dong)施工(gong)(gong)前(qian)(qian)施工(gong)(gong)單位需要通知監理及相關人員到場(chang)，并(bing)按(an)程序辦理施工(gong)(gong)前(qian)(qian)的手續。

涵(han)(han)管(guan)施工(gong)(gong)(gong)(gong)前應設一(yi)名管(guan)道安(an)裝指揮人(ren)(ren)員(yuan)(yuan)，負(fu)責指揮吊裝及(ji)施工(gong)(gong)(gong)(gong)人(ren)(ren)員(yuan)(yuan)的(de)現場操作；設置(zhi)1~2名技術人(ren)(ren)員(yuan)(yuan)負(fu)責放線。涵(han)(han)管(guan)安(an)置(zhi)等控制關鍵技術；同時(shi)配置(zhi)適當的(de)輔助人(ren)(ren)員(yuan)(yuan)。涵(han)(han)洞(dong)施工(gong)(gong)(gong)(gong)前應備(bei)齊(qi)所需的(de)機械設備(bei)及(ji)相關工(gong)(gong)(gong)(gong)具，反開槽回填法(fa)的(de)工(gong)(gong)(gong)(gong)藝流(liu)程為。

鋼(gang)波紋涵管洞施(shi)工(gong)工(gong)藝流程(cheng)可分為(wei)路(lu)堤法和反開槽回填(tian)法，由(you)于后(hou)者涵洞的(de)施(shi)工(gong)多在路(lu)基施(shi)工(gong)結束后(hou)和改建涵洞，所以不影響路(lu)基施(shi)工(gong)整(zheng)體進度(du)，一般(ban)后(hou)者較為(wei)多見(jian)。盡管在外力上二者存在一定(ding)的(de)差異，但施(shi)工(gong)工(gong)藝相差不大。下面分別予(yu)以敘述。
