鋼波紋涵管解決了勻稱地基沉降的難題！！

鋼波紋涵管選用規(gui)范化設(she)計方(fang)案，生產制造(zao)，設(she)計方(fang)案簡(jian)易，生產制造(zao)周期(qi)時間短；工(gong)(gong)(gong)(gong)程項目具體工(gong)(gong)(gong)(gong)程造(zao)價比類似(si)跨距的(de)橋(qiao)，涵(han)洞(dong)低；工(gong)(gong)(gong)(gong)程施工(gong)(gong)(gong)(gong)短工(gong)(gong)(gong)(gong)期(qi)，關鍵為組裝工(gong)(gong)(gong)(gong)程施工(gong)(gong)(gong)(gong)；金屬材料波紋涵(han)管替代混凝土結構(gou)開展(zhan)涵(han)洞(dong)工(gong)(gong)(gong)(gong)程施工(gong)(gong)(gong)(gong)，不管從工(gong)(gong)(gong)(gong)程施工(gong)(gong)(gong)(gong)周期(qi)時間，工(gong)(gong)(gong)(gong)程施工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)程造(zao)價，環境保護實際意義(yi)等(deng)層面都是有其不能類比的(de)優勢。

鋼波(bo)(bo)紋(wen)(wen)(wen)(wen)(wen)涵管(guan)(guan)具(ju)備(bei)卓 越的(de)(de)橋用特性，尤(you)其(qi)是對路(lu)(lu)基規定低，工(gong)程施工(gong)簡單(dan)，能(neng)(neng)(neng)迅速安裝。大(da)大(da)縮短施工(gong)期，是一(yi)(yi)般涵管(guan)(guan)沒(mei)法(fa)對比的(de)(de)，鋼波(bo)(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)涵在道路(lu)(lu)新改造工(gong)程、路(lu)(lu)基工(gong)程保養工(gong)程項(xiang)目里(li)將充分(fen)發揮積J的(de)(de)功效。鋼波(bo)(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)做為(wei)一(yi)(yi)種軟性結(jie)構，它能(neng)(neng)(neng)不錯地(di)融入路(lu)(lu)基土(tu)的(de)(de)不勻稱地(di)基沉降狀況(kuang)。鋼波(bo)(bo)紋(wen)(wen)(wen)(wen)(wen)管(guan)(guan)中(zhong) 心(xin)線(xian)上的(de)(de)波(bo)(bo)浪紋(wen)(wen)(wen)(wen)(wen)大(da)大(da)增加了截(jie)面(mian)慣(guan)性矩，提升了承載能(neng)(neng)(neng)力(li)(li)，又由于其(qi)周邊砂(sha)土(tu)可以融合鋼波(bo)(bo)浪紋(wen)(wen)(wen)(wen)(wen)骨一(yi)(yi)同承受(shou)力(li)(li)，能(neng)(neng)(neng)夠 在更多(duo)方面(mian)上把載荷的(de)(de)集中(zhong)化(hua)地(di)應力(li)(li)給予分(fen)散化(hua)。

鋼波紋涵(han)管(guan)(guan)及管(guan)(guan)座安(an)裝時質量檢(jian)(jian)驗規(gui)定，鋼波紋涵(han)管(guan)(guan)須檢(jian)(jian)測達標(biao)即可安(an)裝。

a、承載(zai)力須考慮工(gong)程圖紙規定，波紋(wen)涵管與管座、基礎(chu)墊層或路基密不可分(fen)迎合(he)，墊穩座實。

b、接(jie)縫處(chu)填充(chong)料嵌填密實度，接(jie)縫處(chu)表層整平，不間斷(duan)、縫隙、墻面(mian)空鼓狀況。

c、各節層底傾(qing)斜度均不(bu)可出現反坡。

d、管座(zuo)變形(xing)縫應與(yu)涵(han)三通(tong)接頭齊(qi)平(ping)，無移位(wei)狀況。

e、規定防漏水的倒虹(hong)吸涵管須(xu)做漏水實驗，漏水量應符合(he)要求。

鋼波紋涵管有(you)益于改進軟(ruan)基處(chu)理，膨脹(zhang)土(tu)(tu)，濕(shi)陷性(xing)等獨特(te)路基結(jie)構物處(chu)的不勻稱地基沉降(jiang)難題(ti)，提升了道(dao)路服務(wu)項目特(te)性(xing)，降(jiang)低了工(gong)后保養(yang)成本費(fei)；降(jiang)低了混(hun)凝土(tu)(tu)，塊塊石或砂(sha)(sha)礫石，砂(sha)(sha)等的使用量，有(you)益于環境(jing)保護(hu)；沿(yan)海地區(qu)地表水(shui)多含有(you)不一樣水(shui)平的腐蝕，另外山嶺(ling)重丘地域土(tu)(tu)層水(shui)流湍急(ji)，周期性(xing)降(jiang)水(shui)沖洗比較嚴重。鋼波(bo)紋涵(han)(han)管(guan)是(shi)取(qu)代圓管(guan)涵(han)(han)、蓋板涵(han)(han)、拱涵(han)(han)和竹橋的優。質道(dao)路裝飾(shi)建材。

在山區修建高(gao)速公(gong)路(lu)，為達到(dao)(dao)zui終(zhong)的(de)(de)(de)設計要求，深挖高(gao)填(tian)這種情況經常(chang)(chang)能遇到(dao)(dao)，因此產生的(de)(de)(de)高(gao)填(tian)方(fang)路(lu)堤(di)下的(de)(de)(de)涵(han)洞工程越來越多。以(yi)前，高(gao)填(tian)方(fang)涵(han)洞一般為鋼(gang)筋混凝土拱涵(han)或(huo)蓋(gai)板涵(han)，而(er)地(di)基的(de)(de)(de)不均勻沉降導致涵(han)洞的(de)(de)(de)開裂(lie)或(huo)拱圈的(de)(de)(de)開裂(lie)與塌陷(xian)，進一步引起路(lu)面(mian)的(de)(de)(de)沉降破壞(huai)，從(cong)而(er)影響上(shang)方(fang)公(gong)路(lu)的(de)(de)(de)正常(chang)(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/
