鋼波紋管從材料(liao)與結構和(he)功能的本(ben)質關系上分析,選(xuan)用柔性(xing)高強度(du)的鋼波紋管洞因為軸向波紋的存(cun)在,使其具有受力特征(zheng),軸向和(he)徑(jing)向同時(shi)分布因荷載引起的應(ying)力應(ying)變,可以更大(da)程度(du)上渙(huan)散荷載的應(ying)力會集,更好(hao)地發揮鋼結構的優勢(shi)。
鋼波紋管經濟耐用的原因無人問津
鋼波(bo)紋(wen)(wen)管具有施工(gong)工(gong)期短(duan)、重量輕(qing)、安裝方便、耐久(jiu)性能好、工(gong)程(cheng)造價低、抗(kang)變形能力(li)強、減少(shao)維護費用成本等優點。鋼波(bo)紋(wen)(wen)管是一種柔(rou)性構(gou)造,波(bo)紋(wen)(wen)管在構(gou)造上(shang)具有橫向(xiang)抵償位移特(te)性,可充分發揮(hui)鋼材抗(kang)拉功能強。
具(ju)有較大的抗變形和(he)(he)抗沉(chen)降才干,施工過程中重(zhong)量輕、設備方便(bian)快捷、施工簡潔(jie)等許(xu)多(duo)(duo)(duo)優(you)點。鋼波(bo)紋(wen)(wen)(wen)管(guan)(guan)按(an)構(gou)成(cheng)材(cai)料可(ke)分(fen)為金屬波(bo)紋(wen)(wen)(wen)管(guan)(guan)、非金屬波(bo)紋(wen)(wen)(wen)管(guan)(guan)兩(liang)種;按(an)構(gou)造可(ke)分(fen)為單層(ceng)和(he)(he)多(duo)(duo)(duo)層(ceng)。單層(ceng)波(bo)紋(wen)(wen)(wen)管(guan)(guan)應用較多(duo)(duo)(duo)。多(duo)(duo)(duo)層(ceng)波(bo)紋(wen)(wen)(wen)管(guan)(guan)強度高,耐久性(xing)好(hao),應力小,用在(zai)重(zhong)要(yao)的測量中。
鋼(gang)(gang)波紋管的(de)材料(liao)普通為青銅(tong)、黃銅(tong)、不銹鋼(gang)(gang)、蒙(meng)乃爾合金(jin)(jin)和因康鎳爾合金(jin)(jin)等。鋼(gang)(gang)波紋管選用規范化設(she)計方案,出(chu)產制(zhi)作,設(she)計方案簡(jian)易,出(chu)產制(zhi)作周期時間短;工(gong)(gong)程(cheng)項目具體工(gong)(gong)程(cheng)造價比類似跨(kua)距的(de)橋,洞低(di);工(gong)(gong)程(cheng)施(shi)工(gong)(gong)短工(gong)(gong)期,要害(hai)為組(zu)裝工(gong)(gong)程(cheng)施(shi)工(gong)(gong);金(jin)(jin)屬(shu)材料(liao)波紋管替(ti)代混(hun)凝土結構展(zhan)開洞工(gong)(gong)程(cheng)施(shi)工(gong)(gong)。
不(bu)管從(cong)工程(cheng)(cheng)施工周(zhou)期時間,工程(cheng)(cheng)施工工程(cheng)(cheng)造價,環境保護實際意義等(deng)層面都是有(you)其不(bu)能類比的(de)(de)優勢。鋼波(bo)紋管有(you)益于改善(shan)軟(ruan)基(ji)處理,膨脹土,濕陷性等(deng)共(gong)同(tong)路基(ji)結構(gou)物處的(de)(de)不(bu)勻(yun)稱地基(ji)沉降難題。
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/
