鋼波紋涵管

公(gong)路工(gong)(gong)程(cheng)的涵(han)(han)洞(dong)(dong)一般選(xuan)用金(jin)(jin)屬(shu)(shu)(shu)筋混(hun)凝(ning)土(tu)制作。現選(xuan)用金(jin)(jin)屬(shu)(shu)(shu)鋼(gang)波(bo)紋(wen)涵(han)(han)管替代(dai)(dai)金(jin)(jin)屬(shu)(shu)(shu)筋混(hun)凝(ning)土(tu)進行涵(han)(han)洞(dong)(dong)施(shi)工(gong)(gong)在(zai)國內時(shi)一項新技術，金(jin)(jin)屬(shu)(shu)(shu)鋼(gang)波(bo)紋(wen)涵(han)(han)管以其(qi)功(gong)能穩定(ding)、裝置便(bian)利、有利環保、造價(jia)低等(deng)優(you)點迅(xun)速在(zai)公(gong)路施(shi)工(gong)(gong)中替代(dai)(dai)了金(jin)(jin)屬(shu)(shu)(shu)筋混(hun)凝(ning)土(tu)施(shi)工(gong)(gong)的涵(han)(han)洞(dong)(dong)，發展(zhan)前景十(shi)分寬廣(guang)。

鋼(gang)波紋涵(han)(han)管(guan)的(de)開(kai)展在(zai)咱們高速公路建(jian)設過程中(zhong)，涵(han)(han)洞(dong)(dong)是一(yi)種(zhong)常見(jian)的(de)結構也(ye)是一(yi)種(zhong)十分重(zhong)要的(de)結構，涵(han)(han)洞(dong)(dong)結構一(yi)直選用箱涵(han)(han)、蓋板涵(han)(han)、圓(yuan)管(guan)涵(han)(han)、拱涵(han)(han)等(deng)幾(ji)種(zhong)型式，涵(han)(han)洞(dong)(dong)在(zai)施工中(zhong)存在(zai)規劃繁瑣，施工時間(jian)周期(qi)長(chang)，涵(han)(han)洞(dong)(dong)的(de)孔(kong)徑周期(qi)小容易呈現沉降和(he)跳車等(deng)問題(ti)。

鋼波(bo)紋涵管(guan)不能(neng)直接置于巖(yan)石(shi)或混凝(ning)土基(ji)床上，因過于剛性(xing)的支(zhi)承(cheng)，不但會(hui)降(jiang)低管(guan)壁本身所具(ju)有(you)的突出柔性(xing)，并(bing)且還會(hui)減小涵管(guan)的承(cheng)載才能(neng)。所以(yi)對巖(yan)石(shi)地基(ji)應挖掉一部分軟巖(yan)，換填一層土，并(bing)認(ren)真夯實。開挖軟巖(yan)溝(gou)槽，不能(neng)運用烈性(xing)炸藥和放深孔炮，以(yi)防(fang)止將(jiang)過多(duo)的外層炸松懈(xie)。巖(yan)石(shi)風化層地基(ji)不能(neng)作為根底，需換填上3D寬度的填土。
