鋼波紋管施(shi)工(gong)的關(guan)鍵的環節(jie)便(bian)是將(jiang)涵(han)管(guan)進(jin)行(xing)(xing)就位(wei),將(jiang)涵(han)管(guan)兩(liang)邊進(jin)行(xing)(xing)分層回填,并要(yao)(yao)檢測(ce)壓(ya)實(shi)度、含(han)水量等,進(jin)出(chu)口處理(li)工(gong)作。鋼(gang)波紋管(guan)涵(han)洞的施(shi)工(gong)時應(ying)留(liu)意以下關(guan)鍵:應(ying)對施(shi)工(gong)的時節(jie)進(jin)行(xing)(xing)嚴(yan)格操控,盡量避免(mian)在冰(bing)凍(dong)(dong)(dong)時節(jie)進(jin)行(xing)(xing)施(shi)工(gong),冰(bing)凍(dong)(dong)(dong)時節(jie)對工(gong)程(cheng)施(shi)工(gong)質量有著嚴(yan)峻的影響,在寒冷冰(bing)凍(dong)(dong)(dong)天氣施(shi)工(gong)不(bu)只要(yao)(yao)嚴(yan)格要(yao)(yao)求根底(di)填換材料(liao)。
并且還要嚴格操控(kong)粉(fen)粘粒含量制(zhi),不然就(jiu)會呈現涵管嚴峻損壞的情況。其(qi)施(shi)(shi)(shi)工工藝流程較為特別,在(zai)施(shi)(shi)(shi)工前要進行以(yi)下工作:施(shi)(shi)(shi)工前預備、施(shi)(shi)(shi)工放樣、設置圍堰、排水清淤以(yi)及(ji)平(ping)整場所等。
在(zai)施(shi)工工作(zuo)中要(yao)對(dui)其壓實度、含水(shui)(shui)量(liang)進(jin)行(xing)(xing)檢測,接(jie)著(zhu)對(dui)水(shui)(shui)準進(jin)行(xing)(xing)丈(zhang)量(liang),基于此,對(dui)施(shi)工根底(di)進(jin)行(xing)(xing)分(fen)層(ceng)回填,檢測壓實度、含水(shui)(shui)量(liang)等,接(jie)著(zhu)要(yao)組裝管(guan)節,對(dui)工程的密水(shui)(shui)情況(kuang)及管(guan)底(di)縱坡進(jin)行(xing)(xing)檢測,并(bing)對(dui)防腐(fu)涂層(ceng)進(jin)行(xing)(xing)檢測與(yu)補救。
(1)鋼波紋(wen)管習慣地(di)基(ji)變形(xing)能(neng)力強,對地(di)基(ji)承載能(neng)力、平整(zheng)度要求較低(di),工(gong)程實踐造價比同類跨徑(jing)的橋、涵洞相(xiang)近(jin)或較低(di)。
(2)鋼波(bo)紋管(guan)施工工期短(duan)是(shi)明顯的優勢,土建工程與(yu)管(guan)節裝置(zhi)可分(fen)隔施行(xing),然后進行(xing)整體(ti)組(zu)裝。
(3)鋼波(bo)紋(wen)管進(jin)行工廠集中化生(sheng)(sheng)產,生(sheng)(sheng)產不受環境影響,有(you)利降低成本、操控質量。
(4)現場裝置(zhi)方便,不需運用大型(xing)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/
