鋼波紋涵管的主要結構參(can)數(shu)包括(kuo)內徑(jing)、外徑(jing)、壁厚、波(bo)距、波(bo)厚、波(bo)紋(wen)數(shu)、層數(shu),兩頭合作(zuo)部(bu)分標(biao)準以及有(you)效長(chang)度、總(zong)長(chang)度等。在一般狀況下(xia),金屬波(bo)紋(wen)管的用戶(hu)應從有(you)關(guan)標(biao)準和(he)(he)制作(zuo)單位的產(chan)品樣本(ben)中選擇金屬波(bo)紋(wen)管,而不是(shi)規劃新產(chan)品。這樣能使研制中的標(biao)題減到起碼(ma),一起還能下(xia)降制作(zuo)本(ben)錢和(he)(he)縮短制作(zuo)周期(qi)。

鋼波紋涵管不能直接置于巖石或混凝土基床上,因過于剛性的支承,不但會下降管壁自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,并認真夯實。//hanihanbj.com/
