鋼波紋管施(shi)工(gong)(gong)的(de)關鍵的(de)環節(jie)便是將涵管(guan)進(jin)(jin)行(xing)(xing)(xing)就位，將涵管(guan)兩(liang)邊進(jin)(jin)行(xing)(xing)(xing)分層回填，并要檢測壓實(shi)度、含水量等，進(jin)(jin)出口(kou)處理(li)工(gong)(gong)作。鋼波(bo)紋管(guan)涵洞(dong)的(de)施(shi)工(gong)(gong)時應(ying)留意以下關鍵：應(ying)對施(shi)工(gong)(gong)的(de)時節(jie)進(jin)(jin)行(xing)(xing)(xing)嚴(yan)格操控(kong)，盡量避免在(zai)冰凍(dong)時節(jie)進(jin)(jin)行(xing)(xing)(xing)施(shi)工(gong)(gong)，冰凍(dong)時節(jie)對工(gong)(gong)程施(shi)工(gong)(gong)質(zhi)量有著嚴(yan)峻的(de)影響，在(zai)寒冷冰凍(dong)天氣施(shi)工(gong)(gong)不只要嚴(yan)格要求(qiu)根底填換材料。

并且還要(yao)(yao)嚴(yan)格(ge)操控粉粘粒含量(liang)制，不然就會(hui)呈現涵管嚴(yan)峻損壞的情況。其(qi)施(shi)工(gong)(gong)工(gong)(gong)藝流程較為特(te)別(bie)，在施(shi)工(gong)(gong)前(qian)要(yao)(yao)進行以下工(gong)(gong)作：施(shi)工(gong)(gong)前(qian)預備、施(shi)工(gong)(gong)放(fang)樣、設置圍堰、排水(shui)清淤(yu)以及平整場(chang)所(suo)等。

在施(shi)工(gong)工(gong)作(zuo)中要對(dui)其壓實(shi)度、含水(shui)量(liang)進(jin)(jin)行(xing)檢(jian)測(ce)，接(jie)著對(dui)水(shui)準(zhun)進(jin)(jin)行(xing)丈(zhang)量(liang)，基于(yu)此(ci)，對(dui)施(shi)工(gong)根(gen)底(di)進(jin)(jin)行(xing)分層回(hui)填，檢(jian)測(ce)壓實(shi)度、含水(shui)量(liang)等，接(jie)著要組裝管節，對(dui)工(gong)程的密水(shui)情況及(ji)管底(di)縱坡進(jin)(jin)行(xing)檢(jian)測(ce)，并對(dui)防腐涂層進(jin)(jin)行(xing)檢(jian)測(ce)與補救。

鋼波紋管

(1)鋼波紋(wen)管習慣(guan)地基(ji)變形(xing)能力強，對地基(ji)承載能力、平整(zheng)度要求較低，工程實踐造價(jia)比(bi)同(tong)類跨徑的橋、涵洞相近(jin)或較低。

(2)鋼波紋管(guan)施工工期短是明(ming)顯的優勢，土建工程與管(guan)節裝置可分隔施行，然后進(jin)行整體組裝。

(3)鋼波紋管進(jin)行工(gong)廠集中化生產，生產不(bu)受(shou)環境影響(xiang)，有(you)利(li)降低成(cheng)本、操控質量。

(4)現(xian)場裝置方便，不需運用大型設備。

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/
