鋼(gang)(gang)波紋涵管(guan)的(de)特征強度(du)高,由于(yu)其獨特的(de)波紋結(jie)構使其比同(tong)口(kou)徑(jing)的(de)水(shui)泥(ni)管(guan)耐壓強度(du)大15倍以上。運輸(shu)方便,鋼(gang)(gang)波紋涵管(guan)的(de)重量只有(you)同(tong)口(kou)徑(jing)水(shui)泥(ni)管(guan)的(de)1/10到1/5,即使在窄的(de)場所沒有(you)運輸(shu)設備,人工也可運輸(shu)。

使用壽命長,鋼波紋涵管是采用(yong)(yong)鋼管熱(re)浸鍍鋅,所以使用(yong)(yong)壽(shou)命(ming)(ming)長,壽(shou)命(ming)(ming)為80-100年(nian),在(zai)腐蝕性特別(bie)大(da)的環(huan)境下(xia)使用(yong)(yong)時,采用(yong)(yong)內(nei)外表面瀝清附層的鋼制波(bo)紋管,可在(zai)原使用(yong)(yong)壽(shou)命(ming)(ming)基(ji)礎上(shang)提高約20年(nian)以上(shang)。

鋼波紋涵管

波紋管涵(han)是與鋼筋混凝土管涵(han)相(xiang)比,具有管節薄,重量輕(qing),便于運輸存放,施工工藝(yi)簡單,組裝(zhuang)快(kuai)速,工期短等優點。

建(jian)筑波紋管(guan)時(shi),可根(gen)據(ju)需要隨意組裝成任何長度,必要時(shi),管(guan)節還(huan)可拆除,遷往別處修建(jian),在缺乏砂石(shi)材料(liao)地區(qu)或地基承載力較低的地區(qu),波紋管(guan)涵(han)的優越(yue)性更為(wei)顯著。

鋼波紋(wen)(wen)(wen)涵(han)管(guan)在國(guo)(guo)外(wai)的公路(lu)、鐵(tie)路(lu)和房(fang)屋建工程(cheng)中早已(yi)被方泛采用(yong),一些(xie)發達 不僅(jin)設有制造波紋(wen)(wen)(wen)管(guan)節的工廠(chang),而且有些(xie) 發布了波紋(wen)(wen)(wen)管(guan)涵(han)的設計與施工規范或規程(cheng)。我國(guo)(guo)解放前公路(lu)、鐵(tie)路(lu)部(bu)門(men)也曾使用(yong)過國(guo)(guo)外(wai)進口(kou)的波紋(wen)(wen)(wen)管(guan)管(guan)節。目前我國(guo)(guo)已(yi)有專門(men)生產(chan)波紋(wen)(wen)(wen)管(guan)涵(han)的工廠(chang),鑒于這種管(guan)涵(han)的許多優點(dian),我國(guo)(guo)鋼材(cai)產(chan)量已(yi)跨(kua)居世(shi)界前列,在我國(guo)(guo)推廣應用(yong)波紋(wen)(wen)(wen)管(guan)涵(han)的前景是非常廣闊(kuo)的。

鋼(gang)波紋涵管(guan)(guan)不(bu)少機器零件(jian),如沖(chong)床的(de)連桿、鍛(duan)錘的(de)錘頭、火車掛鉤、沖(chong)模等,在工(gong)作時(shi)要承受(shou)沖(chong)擊(ji)(ji)載荷、如果仍用靜(jing)載荷作用下的(de)強度(du)限(xian)指標來進行(xing)設計計算(suan),就不(bu)能保(bao)證這(zhe)些零件(jian)工(gong)作時(shi)的(de)安全性(xing),必須同時(shi)考慮材料的(de)韌(ren)性(xing)。波紋涵管(guan)(guan)沖(chong)擊(ji)(ji)韌(ren)性(xing)波紋涵管(guan)(guan)沖(chong)擊(ji)(ji)韌(ren)性(xing)是指材料抵(di)抗沖(chong)擊(ji)(ji)載荷的(de)能力。

鋼(gang)波(bo)紋涵(han)管出廠時,涵(han)管及(ji)配(pei)件(jian)均經過熱浸(jin)鍍鋅(xin)處理,鍍鋅(xin)層平均厚(hou)度(du)大(da)于84μm,在沒有亂(luan)石(shi)沖刷的(de)情況(kuang)下,它的(de)鍍鋅(xin)層就(jiu)可防止銹蝕(shi)(shi)。目前內涵(han)管出廠前,根據(ju)鋼(gang)管管壁每(mei)年(nian)蝕(shi)(shi)耗厚(hou)度(du)0.01-0.03mm,都比(bi)外涵(han)管做的(de)要保守,比(bi)正常管壁厚(hou)度(du)增加了0.5mm,可提高使用壽命,而且涵(han)管運(yun)至施工(gong)現場(chang)后,工(gong)地涂(tu)(tu)涮兩遍瀝(li)青,瀝(li)青涂(tu)(tu)層厚(hou)度(du)達到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/
