鋼波紋管的(de)(de)(de)波紋結構(gou)可使(shi)(shi)涵洞(dong)路面受(shou)力合理,荷載散布均勻(yun),并具有必定(ding)的(de)(de)(de)抗變(bian)形(xing)才能(neng),能(neng)解決(jue)北方寒冷(leng)地(di)區(霜(shuang)凍)對(dui)橋梁和管涵砼(tong)結構(gou)的(de)(de)(de)破壞問題;使(shi)(shi)路外表沒有伸(shen)縮縫,進(jin)步行車舒服。并且(qie)也(ye)有利于改進(jin)軟土地(di)基(ji)結構(gou)與(yu)路堤交界處的(de)(de)(de)“錯臺”現象,進(jin)步行車的(de)(de)(de)安(an)全性(xing)。

鋼(gang)波(bo)紋(wen)(wen)管(guan)涵(han)(han)(han)的工后(hou)營(ying)運、維護成本低,工程實際造價也低于同類(lei)跨徑的橋梁、涵(han)(han)(han)洞。金屬波(bo)紋(wen)(wen)管(guan)涵(han)(han)(han)也叫波(bo)紋(wen)(wen)管(guan)涵(han)(han)(han),是指鋪(pu)埋(mai)在公路、鐵路路下的涵(han)(han)(han)洞用的螺紋(wen)(wen)波(bo)紋(wen)(wen)管(guan),它是由波(bo)形(xing)鋼(gang)板卷(juan)制成或用波(bo)形(xing)鋼(gang)片組拼成的圓形(xing)鋼(gang)結構管(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.

應用于(yu)公路,鐵路,小(xiao)橋(qiao),通道(dao)(dao),擋土墻以及各種礦場,巷道(dao)(dao)擋墻支護等工程中的涵洞(管(guan))。當鋼(gang)制波紋管(guan)涵處于(yu)軟(ruan)土地基上(shang)時,需(xu)對軟(ruan)土路基進行處理,然后,在其上(shang)填(tian)一層(ceng)大于(yu)20cm厚(hou)的砂礫墊層(ceng),并夯實嚴密。承(cheng)載才能不(bu)太高(gao)的一般地基,需(xu)設必定厚(hou)度的根底。

可是(shi),若將涵管底基(ji)槽原狀(zhuang)土(tu)經嚴厲夯(hang)(hang)實(其夯(hang)(hang)實度(du)到(dao)重型擊實密(mi)實度(du)的90%以(yi)(yi)上)以(yi)(yi)后,也可直(zhi)接將鋼制波紋(wen)管涵置于地(di)基(ji)上。未(wei)經篩分的砂,碎石,砂礫(li)土(tu)以(yi)(yi)及砂質土(tu)都是(shi)比較理想的地(di)基(ji)材(cai)料,但需鏟除10cm以(yi)(yi)上的石塊等硬物。

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/
