鋼波紋涵管(guan)的(de)特(te)征強(qiang)度高，由于其獨特(te)的(de)波紋結構使(shi)其比同(tong)口徑(jing)的(de)水(shui)泥管(guan)耐壓強(qiang)度大15倍以上。運輸方(fang)便，鋼波紋涵管(guan)的(de)重量只有(you)同(tong)口徑(jing)水(shui)泥管(guan)的(de)1/10到1/5，即(ji)使(shi)在窄(zhai)的(de)場所(suo)沒有(you)運輸設備，人工也可運輸。

使用壽命長，鋼波紋涵管是(shi)采用(yong)鋼管熱浸鍍鋅(xin)，所以使用(yong)壽(shou)命長，壽(shou)命為(wei)80-100年，在(zai)腐(fu)蝕性特別大的環境下(xia)使用(yong)時(shi)，采用(yong)內(nei)外表面瀝清附層的鋼制(zhi)波紋管，可(ke)在(zai)原使用(yong)壽(shou)命基礎上(shang)提高約20年以上(shang)。

鋼波紋涵管

波紋管(guan)涵(han)(han)是與(yu)鋼筋混凝土(tu)管(guan)涵(han)(han)相比，具有管(guan)節薄(bo)，重(zhong)量輕，便于運(yun)輸存(cun)放，施工工藝簡單，組裝快速，工期短等優點。

建筑波(bo)紋(wen)管(guan)時(shi)，可根據需要隨意組裝成任(ren)何長度(du)，必要時(shi)，管(guan)節還可拆除，遷(qian)往別處修建，在缺乏砂石材料(liao)地(di)區(qu)或地(di)基承載力較(jiao)低的地(di)區(qu)，波(bo)紋(wen)管(guan)涵的優越(yue)性更為顯著(zhu)。

鋼波(bo)紋(wen)涵(han)管在國外的(de)公(gong)路(lu)、鐵(tie)(tie)路(lu)和房屋建工(gong)程(cheng)中(zhong)早已被方(fang)泛采(cai)用(yong)，一些(xie)發達 不僅(jin)設(she)有制造波(bo)紋(wen)管節(jie)的(de)工(gong)廠，而(er)且(qie)有些(xie) 發布了波(bo)紋(wen)管涵(han)的(de)設(she)計與施工(gong)規(gui)范或(huo)規(gui)程(cheng)。我國解放前(qian)公(gong)路(lu)、鐵(tie)(tie)路(lu)部門也曾使(shi)用(yong)過國外進口的(de)波(bo)紋(wen)管管節(jie)。目前(qian)我國已有專門生產波(bo)紋(wen)管涵(han)的(de)工(gong)廠，鑒于這種(zhong)管涵(han)的(de)許(xu)多(duo)優點，我國鋼材(cai)產量已跨居世界前(qian)列，在我國推廣應用(yong)波(bo)紋(wen)管涵(han)的(de)前(qian)景是非(fei)常廣闊的(de)。

鋼波紋(wen)涵(han)管(guan)不少(shao)機器零(ling)(ling)件，如沖(chong)(chong)床(chuang)的(de)連(lian)桿、鍛(duan)錘(chui)的(de)錘(chui)頭、火車掛鉤、沖(chong)(chong)模(mo)等，在(zai)工作時要承受沖(chong)(chong)擊載(zai)荷(he)、如果仍用靜(jing)載(zai)荷(he)作用下的(de)強度(du)限指(zhi)標來(lai)進行設計(ji)計(ji)算，就不能保證(zheng)這些(xie)零(ling)(ling)件工作時的(de)安全性(xing)，必(bi)須同(tong)時考慮材料(liao)的(de)韌性(xing)。波紋(wen)涵(han)管(guan)沖(chong)(chong)擊韌性(xing)波紋(wen)涵(han)管(guan)沖(chong)(chong)擊韌性(xing)是指(zhi)材料(liao)抵抗沖(chong)(chong)擊載(zai)荷(he)的(de)能力(li)。

鋼波(bo)紋涵(han)管(guan)出廠時，涵(han)管(guan)及配件均經過(guo)熱浸鍍鋅處理(li)，鍍鋅層平均厚(hou)度(du)(du)(du)大于84μm，在(zai)沒有亂石沖刷的(de)情況下(xia)，它的(de)鍍鋅層就(jiu)可(ke)防止銹蝕。目前(qian)內涵(han)管(guan)出廠前(qian)，根據鋼管(guan)管(guan)壁每(mei)年蝕耗厚(hou)度(du)(du)(du)0.01-0.03mm，都比(bi)外(wai)涵(han)管(guan)做的(de)要(yao)保(bao)守(shou)，比(bi)正常管(guan)壁厚(hou)度(du)(du)(du)增(zeng)加了0.5mm，可(ke)提高(gao)使用(yong)壽(shou)命，而且涵(han)管(guan)運至(zhi)施工現(xian)場后(hou)，工地(di)涂(tu)涮兩遍瀝(li)青(qing)，瀝(li)青(qing)涂(tu)層厚(hou)度(du)(du)(du)達到(dao)0.3-0.5mm。

并且根據內車輛超載運輸的實際情況，還對YTHG鋼波紋涵管的技術參數（波距、波深、壁厚）進行了調整，增大了涵管在內使用的保險系數。以上幾種措施即可滿足使用要求，使用壽命完全能適合公路的需求，更能滿足受流石沖刷的涵洞，確保流石對涵管管壁的沖擊。//hanihanbj.com/
