鋼波紋管施(shi)工(gong)(gong)的(de)關鍵的(de)環節便(bian)是(shi)將涵管(guan)進行就位，將涵管(guan)兩邊進行分層回填(tian)(tian)，并要檢(jian)測壓(ya)實(shi)度(du)、含水量等，進出口處(chu)理工(gong)(gong)作。鋼(gang)波紋管(guan)涵洞的(de)施(shi)工(gong)(gong)時應留意以下關鍵：應對施(shi)工(gong)(gong)的(de)時節進行嚴格操控，盡(jin)量避免(mian)在冰(bing)凍時節進行施(shi)工(gong)(gong)，冰(bing)凍時節對工(gong)(gong)程施(shi)工(gong)(gong)質量有(you)著嚴峻的(de)影響(xiang)，在寒冷冰(bing)凍天氣(qi)施(shi)工(gong)(gong)不只(zhi)要嚴格要求根底填(tian)(tian)換材料(liao)。
并且還要(yao)嚴格操控粉粘粒含量制，不(bu)然就會呈現涵(han)管嚴峻損壞的情況。其(qi)施(shi)工(gong)(gong)工(gong)(gong)藝流程較為特(te)別，在(zai)施(shi)工(gong)(gong)前要(yao)進行以下工(gong)(gong)作：施(shi)工(gong)(gong)前預備、施(shi)工(gong)(gong)放樣、設置圍堰、排水清淤以及平整場所(suo)等。
在施(shi)工(gong)工(gong)作中要(yao)對其壓實度(du)(du)、含水量(liang)進(jin)行(xing)檢(jian)測，接著對水準進(jin)行(xing)丈量(liang)，基于此，對施(shi)工(gong)根底(di)進(jin)行(xing)分層回填(tian)，檢(jian)測壓實度(du)(du)、含水量(liang)等，接著要(yao)組裝(zhuang)管節，對工(gong)程的密水情況及管底(di)縱坡進(jin)行(xing)檢(jian)測，并對防腐涂層進(jin)行(xing)檢(jian)測與補(bu)救(jiu)。
(1)鋼波紋(wen)管習慣地(di)基變形能(neng)力強，對地(di)基承載能(neng)力、平整(zheng)度要求較(jiao)低，工(gong)程實踐造價比同(tong)類跨徑(jing)的橋、涵洞相近或(huo)較(jiao)低。
(2)鋼波(bo)紋(wen)管施(shi)工(gong)工(gong)期(qi)短是明顯的優勢，土建工(gong)程(cheng)與管節(jie)裝(zhuang)置(zhi)可(ke)分隔施(shi)行(xing)，然后進行(xing)整體組裝(zhuang)。
(3)鋼波紋管進行工(gong)廠(chang)集中化生(sheng)產，生(sheng)產不受環境影響(xiang)，有利(li)降低成本、操控質(zhi)量(liang)。
(4)現(xian)場裝置方便，不需(xu)運用大型設備。
澆筑砼時，阻止對著波紋管涵斜放，攪拌棒阻止與波紋管涵觸碰，阻止兩個攪拌棒夾著一根波紋管涵攪拌。特別是腹板攪拌時，阻止攪拌棒在同一個當地長時刻攪拌，攪拌時刻不得超越20秒。//hanihanbj.com/
