鋼波紋涵管選用規范化(hua)設計方(fang)案(an)，生產制造，設計方(fang)案(an)簡易(yi)，生產制造周期(qi)時間(jian)短；工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)項目具體工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)造價(jia)比(bi)類似跨距的(de)橋，涵(han)洞(dong)低；工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)短工(gong)(gong)(gong)(gong)(gong)期(qi)，關鍵為組(zu)裝工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)；金屬材料波紋涵(han)管(guan)替代混凝土結(jie)構(gou)開展涵(han)洞(dong)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)，不(bu)管(guan)從工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)周期(qi)時間(jian)，工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)造價(jia)，環境保護實際(ji)意義等層面都是有其不(bu)能類比(bi)的(de)優勢。

鋼(gang)波(bo)(bo)紋(wen)涵管(guan)具備卓 越的(de)橋用特性，尤其是對(dui)路基(ji)(ji)(ji)規定低(di)，工(gong)程(cheng)施工(gong)簡單，能迅速安(an)裝。大(da)大(da)縮(suo)短施工(gong)期，是一般涵管(guan)沒法對(dui)比(bi)的(de)，鋼(gang)波(bo)(bo)紋(wen)管(guan)涵在道路新改造工(gong)程(cheng)、路基(ji)(ji)(ji)工(gong)程(cheng)保(bao)養工(gong)程(cheng)項目里將(jiang)充(chong)分(fen)發揮積J的(de)功效。鋼(gang)波(bo)(bo)紋(wen)管(guan)做為一種(zhong)軟性結構，它(ta)能不錯(cuo)地(di)融(rong)入路基(ji)(ji)(ji)土(tu)的(de)不勻稱地(di)基(ji)(ji)(ji)沉降狀(zhuang)況(kuang)。鋼(gang)波(bo)(bo)紋(wen)管(guan)中 心線(xian)上的(de)波(bo)(bo)浪紋(wen)大(da)大(da)增加了截(jie)面慣性矩，提升(sheng)了承載能力，又由于其周(zhou)邊砂土(tu)可以融(rong)合鋼(gang)波(bo)(bo)浪紋(wen)骨一同(tong)承受(shou)力，能夠 在更多方(fang)面上把載荷(he)的(de)集中化(hua)地(di)應力給予分(fen)散化(hua)。

鋼(gang)波紋(wen)涵管(guan)及管(guan)座(zuo)安(an)裝時(shi)質量檢驗(yan)規定(ding)，鋼(gang)波紋(wen)涵管(guan)須檢測達標即可(ke)安(an)裝。

a、承載力(li)須考慮工(gong)程圖紙規定，波紋涵管與管座(zuo)、基(ji)礎墊層或路基(ji)密不可分(fen)迎合，墊穩(wen)座(zuo)實。

b、接縫處(chu)填充料嵌填密實(shi)度，接縫處(chu)表層整平，不間斷、縫隙、墻面空鼓狀(zhuang)況。

c、各節層(ceng)底傾(qing)斜度(du)均不可(ke)出現反坡。

d、管座變形縫應(ying)與涵三通接(jie)頭(tou)齊平，無移位狀況。

e、規定防(fang)漏水的倒虹吸(xi)涵(han)管須(xu)做漏水實驗，漏水量應符合(he)要(yao)求。

鋼波紋涵管有益于改(gai)進(jin)軟基(ji)處理，膨脹土，濕陷(xian)性等獨特(te)路(lu)基(ji)結構(gou)物處的(de)不(bu)勻(yun)稱地(di)基(ji)沉降(jiang)難題，提升(sheng)了(le)道路(lu)服(fu)務(wu)項目特(te)性，降(jiang)低了(le)工(gong)后(hou)保養成(cheng)本費；降(jiang)低了(le)混凝土，塊(kuai)塊(kuai)石或砂礫石，砂等的(de)使用量(liang)，有益于環境保護(hu)；沿海(hai)地(di)區(qu)地(di)表水多含有不(bu)一樣(yang)水平的(de)腐蝕，另外(wai)山嶺重丘地(di)域土層水流湍急，周期性降(jiang)水沖洗比較嚴重。鋼(gang)波紋涵管是取代圓(yuan)管涵、蓋板涵、拱涵和竹橋的(de)優。質(zhi)道路(lu)裝飾建材。

在山區修建高(gao)速(su)公(gong)路(lu)，為(wei)(wei)達(da)到zui終(zhong)的(de)設計(ji)要(yao)求，深挖高(gao)填這種情況經常(chang)能遇到，因此產生的(de)高(gao)填方路(lu)堤下的(de)涵洞工程越(yue)來越(yue)多。以前(qian)，高(gao)填方涵洞一(yi)般(ban)為(wei)(wei)鋼筋混(hun)凝土(tu)拱涵或蓋板(ban)涵，而地基(ji)的(de)不(bu)均勻沉降導致涵洞的(de)開(kai)裂(lie)或拱圈的(de)開(kai)裂(lie)與(yu)塌陷(xian)，進一(yi)步引起路(lu)面的(de)沉降破壞(huai)，從而影(ying)響上方公(gong)路(lu)的(de)正(zheng)常(chang)運輸。

總體上切向應變力應變zui大值大于軸向zui大值；管頂以切向應變為主。各管徑恒載、活載作用下管側波峰切向和軸向均受位；在管頂波峰和管底波谷以及管側波谷均出現切向受拉、軸向受壓或切向受壓、軸向受拉互補的變化規律；每測一點恒載下切應變較大時，軸向應變則相對較小。鋼波紋涵管具備短工期、重量較輕、安裝便捷、使用性能好、工程預算低、抗形變能力強、降低全線通車后保養成本費等特性。鋼波紋涵管特別是在運用在嚴寒凍土層地域、軟基處理路基工程地區。具備顯著的經濟收益。//hanihanbj.com/
