鋼波紋管從材料與結構和功能的(de)本質關系(xi)上分析(xi),選用柔(rou)性高強度的(de)鋼波紋(wen)管洞因為(wei)軸(zhou)向(xiang)波紋(wen)的(de)存在,使其具有受力(li)特征,軸(zhou)向(xiang)和徑向(xiang)同時分布因荷載引起的(de)應(ying)力(li)應(ying)變,可以更(geng)大程度上渙(huan)散荷載的(de)應(ying)力(li)會集,更(geng)好地發揮鋼結構的(de)優(you)勢。
鋼波紋管經濟耐用的原因無人問津
鋼(gang)波紋(wen)管具(ju)有(you)施工(gong)工(gong)期短、重量輕、安(an)裝(zhuang)方便、耐(nai)久性(xing)能好、工(gong)程(cheng)造價低、抗變形能力強(qiang)、減少維護費用成(cheng)本等優(you)點。鋼(gang)波紋(wen)管是(shi)一種柔性(xing)構(gou)造,波紋(wen)管在構(gou)造上具(ju)有(you)橫向(xiang)抵償位移特性(xing),可充分發揮(hui)鋼(gang)材(cai)抗拉功能強(qiang)。
具有(you)較(jiao)大的抗變形和抗沉降才干,施工過程中重(zhong)量輕、設(she)備(bei)方便快捷(jie)、施工簡潔等許多(duo)優點。鋼波紋(wen)管(guan)(guan)按(an)構成(cheng)材料可(ke)分為金(jin)屬波紋(wen)管(guan)(guan)、非金(jin)屬波紋(wen)管(guan)(guan)兩種;按(an)構造可(ke)分為單(dan)(dan)層(ceng)和多(duo)層(ceng)。單(dan)(dan)層(ceng)波紋(wen)管(guan)(guan)應用較(jiao)多(duo)。多(duo)層(ceng)波紋(wen)管(guan)(guan)強度高,耐久性(xing)好,應力(li)小,用在重(zhong)要的測量中。
鋼波紋管的材料普通為青銅、黃(huang)銅、不銹鋼、蒙乃爾合金(jin)和因(yin)康(kang)鎳爾合金(jin)等。鋼波紋管選用規范(fan)化(hua)設計方案,出(chu)產制作(zuo),設計方案簡易,出(chu)產制作(zuo)周期(qi)時(shi)間短(duan);工(gong)(gong)程(cheng)項(xiang)目具體工(gong)(gong)程(cheng)造(zao)價比類似跨距(ju)的橋(qiao),洞低;工(gong)(gong)程(cheng)施(shi)工(gong)(gong)短(duan)工(gong)(gong)期(qi),要害為組裝工(gong)(gong)程(cheng)施(shi)工(gong)(gong);金(jin)屬材料波紋管替代(dai)混凝土結構展開洞工(gong)(gong)程(cheng)施(shi)工(gong)(gong)。
不管(guan)(guan)從工(gong)(gong)程(cheng)施(shi)(shi)工(gong)(gong)周期時(shi)間,工(gong)(gong)程(cheng)施(shi)(shi)工(gong)(gong)工(gong)(gong)程(cheng)造價(jia),環境保護實(shi)際意義等(deng)層面(mian)都(dou)是有(you)(you)其不能(neng)類比的優勢。鋼波紋管(guan)(guan)有(you)(you)益(yi)于改善(shan)軟基(ji)處理,膨脹土,濕陷性等(deng)共同(tong)路基(ji)結構物(wu)處的不勻稱地(di)基(ji)沉降難題(ti)。
提升了道路服務項目特性,降低了工后保養成本費;降低了混凝土,塊塊石或砂礫石,砂等的使用量,有益于環境保護;沿海地區地表水多含有不一樣水平的腐蝕,別的山嶺重丘地域土層水流湍急,周期性降水沖刷比較嚴重。//hanihanbj.com/
