鋼波紋管(guan)有著工(gong)程造(zao)價低、施(shi)工(gong)簡潔(jie)方便(bian)工(gong)期短、抗震抗變形(xing)(xing)才能強、管(guan)體(ti)強度(du)高(gao)、耐久性(xing)強壽(shou)命長(chang)、利(li)于環保等長(chang)處，它能夠組裝銜接，能夠整管(guan)銜接，能夠做成拱形(xing)(xing)、橢圓(yuan)形(xing)(xing)、馬蹄形(xing)(xing)、簸箕形(xing)(xing)等以(yi)適應各種要求。一起，運用方面也十分廣，公(gong)路與鐵路范(fan)疇(chou)運用：涵洞、通道(dao)、小橋、地道(dao)、涵隧(sui)大修、暫(zan)時便(bian)道(dao)、滲水(shui)井。

鋼波紋涵管

公(gong)路工(gong)(gong)程的(de)(de)涵洞(dong)一般選(xuan)用金(jin)(jin)屬(shu)(shu)筋(jin)混(hun)凝(ning)土(tu)(tu)制作。現選(xuan)用金(jin)(jin)屬(shu)(shu)鋼波紋(wen)涵管(guan)替代金(jin)(jin)屬(shu)(shu)筋(jin)混(hun)凝(ning)土(tu)(tu)進行涵洞(dong)施(shi)工(gong)(gong)在國(guo)內(nei)時一項(xiang)新技術，金(jin)(jin)屬(shu)(shu)鋼波紋(wen)涵管(guan)以其(qi)功能穩定(ding)、裝(zhuang)置便利、有(you)利環保、造價低等優(you)點迅(xun)速在公(gong)路施(shi)工(gong)(gong)中替代了(le)金(jin)(jin)屬(shu)(shu)筋(jin)混(hun)凝(ning)土(tu)(tu)施(shi)工(gong)(gong)的(de)(de)涵洞(dong)，發展前景十分寬廣。

鋼波(bo)紋涵(han)(han)管(guan)的開展在(zai)咱們高(gao)速公路建(jian)設過程中，涵(han)(han)洞(dong)(dong)(dong)是一(yi)種常見的結構也(ye)是一(yi)種十分重(zhong)要(yao)的結構，涵(han)(han)洞(dong)(dong)(dong)結構一(yi)直選用箱涵(han)(han)、蓋板涵(han)(han)、圓管(guan)涵(han)(han)、拱涵(han)(han)等幾種型(xing)式，涵(han)(han)洞(dong)(dong)(dong)在(zai)施(shi)工中存在(zai)規劃繁瑣，施(shi)工時間周期(qi)長，涵(han)(han)洞(dong)(dong)(dong)的孔徑周期(qi)小容(rong)易呈現沉降和(he)跳(tiao)車等問題。

鋼波紋(wen)涵管不能直接置(zhi)于(yu)巖(yan)(yan)(yan)石(shi)或(huo)混凝土基床上，因過于(yu)剛性的(de)支承，不但會(hui)(hui)降低管壁本身(shen)所具有的(de)突出柔(rou)性，并且還會(hui)(hui)減小涵管的(de)承載才能。所以(yi)對巖(yan)(yan)(yan)石(shi)地基應挖掉一(yi)部(bu)分軟巖(yan)(yan)(yan)，換填(tian)一(yi)層土，并認真(zhen)夯實。開挖軟巖(yan)(yan)(yan)溝(gou)槽，不能運用烈(lie)性炸(zha)藥和放深孔炮，以(yi)防(fang)止將過多的(de)外層炸(zha)松懈。巖(yan)(yan)(yan)石(shi)風化層地基不能作為根(gen)底，需換填(tian)上3D寬度的(de)填(tian)土。
