鋼波紋管從材料(liao)與結(jie)構和功能(neng)的(de)(de)(de)本(ben)質關系上(shang)分(fen)析,選用柔性(xing)高(gao)強度的(de)(de)(de)鋼(gang)波紋(wen)管洞(dong)因為軸(zhou)(zhou)向波紋(wen)的(de)(de)(de)存在(zai),使其具有(you)受(shou)力(li)特征,軸(zhou)(zhou)向和徑(jing)向同時(shi)分(fen)布(bu)因荷(he)載引起(qi)的(de)(de)(de)應力(li)應變,可以(yi)更大(da)程度上(shang)渙(huan)散荷(he)載的(de)(de)(de)應力(li)會集,更好地發揮(hui)鋼(gang)結(jie)構的(de)(de)(de)優勢(shi)。
鋼波紋管經濟耐用的原因無人問津
鋼波紋(wen)(wen)管具(ju)有施工(gong)工(gong)期短、重量輕、安裝(zhuang)方便、耐久性能(neng)好、工(gong)程造(zao)價低、抗變形能(neng)力強、減少維護(hu)費用成本(ben)等優(you)點。鋼波紋(wen)(wen)管是一(yi)種柔性構造(zao),波紋(wen)(wen)管在構造(zao)上具(ju)有橫向(xiang)抵償位(wei)移特性,可充分發揮鋼材抗拉功能(neng)強。
具有較大的抗變形和抗沉降才(cai)干,施工過程(cheng)中重量輕、設(she)備方便(bian)快捷、施工簡潔(jie)等(deng)許多(duo)優點。鋼波(bo)紋(wen)管(guan)(guan)按(an)構(gou)成(cheng)材料可分(fen)為金屬(shu)波(bo)紋(wen)管(guan)(guan)、非金屬(shu)波(bo)紋(wen)管(guan)(guan)兩種;按(an)構(gou)造可分(fen)為單層(ceng)(ceng)(ceng)和多(duo)層(ceng)(ceng)(ceng)。單層(ceng)(ceng)(ceng)波(bo)紋(wen)管(guan)(guan)應用較多(duo)。多(duo)層(ceng)(ceng)(ceng)波(bo)紋(wen)管(guan)(guan)強(qiang)度高,耐久性好,應力小(xiao),用在重要的測量中。
鋼波(bo)紋管的材(cai)料普(pu)通為青(qing)銅(tong)、黃銅(tong)、不(bu)銹鋼、蒙(meng)乃爾合(he)金(jin)(jin)(jin)和(he)因康鎳(nie)爾合(he)金(jin)(jin)(jin)等。鋼波(bo)紋管選用規范化設計(ji)方(fang)案,出(chu)產(chan)制(zhi)作(zuo),設計(ji)方(fang)案簡易(yi),出(chu)產(chan)制(zhi)作(zuo)周期時間短;工(gong)(gong)程(cheng)(cheng)項目具體(ti)工(gong)(gong)程(cheng)(cheng)造價比類似跨距(ju)的橋,洞低(di);工(gong)(gong)程(cheng)(cheng)施工(gong)(gong)短工(gong)(gong)期,要害為組裝工(gong)(gong)程(cheng)(cheng)施工(gong)(gong);金(jin)(jin)(jin)屬材(cai)料波(bo)紋管替代(dai)混(hun)凝(ning)土(tu)結(jie)構展開洞工(gong)(gong)程(cheng)(cheng)施工(gong)(gong)。
不管從(cong)工(gong)(gong)程施工(gong)(gong)周(zhou)期時間(jian),工(gong)(gong)程施工(gong)(gong)工(gong)(gong)程造價,環境保護實(shi)際意義等層(ceng)面都是有(you)其不能(neng)類(lei)比的優勢。鋼波紋(wen)管有(you)益(yi)于改善軟基處理,膨(peng)脹(zhang)土,濕陷性等共同路基結構物處的不勻稱地基沉降(jiang)難題。
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/
