鋼波紋管的(de)波紋結(jie)構(gou)(gou)可使涵洞路(lu)面受力合(he)理,荷載散布均(jun)勻,并(bing)具有(you)必定的(de)抗(kang)變形才能,能解決北方(fang)寒冷地區(霜凍)對橋梁和管涵砼(tong)結(jie)構(gou)(gou)的(de)破壞問題;使路(lu)外表沒有(you)伸縮縫(feng),進(jin)步行車舒服。并(bing)且(qie)也有(you)利(li)于(yu)改進(jin)軟土地基結(jie)構(gou)(gou)與(yu)路(lu)堤交(jiao)界處的(de)“錯臺”現象(xiang),進(jin)步行車的(de)安全(quan)性(xing)。

鋼(gang)波紋(wen)管(guan)(guan)(guan)涵的(de)工(gong)后營運、維(wei)護(hu)成(cheng)本低(di),工(gong)程(cheng)實(shi)際造價也(ye)低(di)于同類跨徑(jing)的(de)橋梁、涵洞(dong)。金屬波紋(wen)管(guan)(guan)(guan)涵也(ye)叫波紋(wen)管(guan)(guan)(guan)涵,是指鋪埋在公(gong)路、鐵路路下(xia)的(de)涵洞(dong)用(yong)的(de)螺紋(wen)波紋(wen)管(guan)(guan)(guan),它是由(you)波形(xing)(xing)鋼(gang)板卷制成(cheng)或用(yong)波形(xing)(xing)鋼(gang)片組拼成(cheng)的(de)圓形(xing)(xing)鋼(gang)結構管(guan)(guan)(guan)。

The operation and maintenance cost of steel corrugated pipe culvert after construction is low, and the actual cost of the project is also lower than that of bridges and culverts with the same span. Metal corrugated pipe culvert, also called corrugated pipe culvert, refers to the threaded corrugated pipe used for Culverts buried under roads and railways. It is a circular steel structure pipe made of corrugated steel plate or assembled with corrugated steel sheet.

應(ying)用(yong)于公路(lu),鐵路(lu),小橋(qiao),通(tong)道,擋土(tu)墻(qiang)(qiang)以及各(ge)種礦(kuang)場,巷(xiang)道擋墻(qiang)(qiang)支(zhi)護等工程(cheng)中的(de)涵洞(管(guan))。當鋼制(zhi)波紋管(guan)涵處于軟土(tu)地基(ji)(ji)上(shang)時,需(xu)對軟土(tu)路(lu)基(ji)(ji)進行(xing)處理,然后,在其上(shang)填一(yi)層(ceng)大于20cm厚(hou)的(de)砂礫墊層(ceng),并夯實嚴密。承載才能不太高的(de)一(yi)般地基(ji)(ji),需(xu)設必(bi)定厚(hou)度的(de)根底。

可是,若將(jiang)涵管底基(ji)槽原(yuan)狀土(tu)(tu)經嚴厲夯實(其夯實度到重(zhong)型擊(ji)實密實度的(de)90%以(yi)上(shang)(shang))以(yi)后,也可直(zhi)接將(jiang)鋼制(zhi)波紋管涵置于地(di)基(ji)上(shang)(shang)。未(wei)經篩分(fen)的(de)砂(sha),碎石,砂(sha)礫土(tu)(tu)以(yi)及砂(sha)質土(tu)(tu)都是比較理想(xiang)的(de)地(di)基(ji)材料,但(dan)需鏟除(chu)10cm以(yi)上(shang)(shang)的(de)石塊等(deng)硬物。

鋼制波紋管涵不能直接置于巖石或混凝土基床上,因過于剛性的支承,不但會降低管壁本身所具有的突出柔性,并且還會減小涵管的承載才能。所以對巖石地基應挖掉一部分軟巖,換填一層土,并仔細夯實。開挖軟巖溝槽,不能使用烈性炸藥和放深孔炮,以防止將過多的外層炸松懈。巖石風化層地基不能作為根底,需換填上3D寬度的填土。//hanihanbj.com/
