薄薄的一塊鋼板就能將一座橋支撐起來?這種說法聽起來似乎不切實際,但是鋼波紋涵管以它特殊(shu)的(de)物理(li)結構(gou)就(jiu)能做到這一點(dian)(dian)。鋼(gang)波(bo)紋涵(han)管(guan)以其性能穩定、安裝方便、有利環保(bao)、造價(jia)低(di)等(deng)優(you)點(dian)(dian)迅速在公路施工中代替了鋼(gang)筋混(hun)凝土施工的(de)涵(han)洞(dong),發展前景非常(chang)廣闊。鋼(gang)波(bo)紋涵(han)管(guan)是將(jiang)鍍鋅鋼(gang)帶(dai)軋制成一定的(de)波(bo)形(xing)后(hou),經過彎曲、傾斜螺旋后(hou)使鋼(gang)帶(dai)邊緣(yuan)相互咬合而成的(de)連續的(de)圓形(xing)管(guan)狀(zhuang)體,是一種代替水泥管(guan)及鋼(gang)筋混(hun)凝土結構(gou)的(de)理(li)想產品。

鋼波紋(wen)涵管代替鋼筋混凝土進(jin)行涵洞施工

在公(gong)路(lu)施(shi)(shi)工(gong)(gong)中(zhong),應用(yong)(yong)(yong)鋼(gang)波(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)(guan)代替(ti)鋼(gang)筋混凝土進(jin)行(xing)涵(han)(han)洞施(shi)(shi)工(gong)(gong)的歷史已經有100多年了(le)(le)。1896年,美(mei)國(guo)率行(xing)鋼(gang)波(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)(guan)通(tong)道(dao)、涵(han)(han)管(guan)(guan)(guan)(guan)(guan)的可行(xing)性(xing)研究。其后,在美(mei)國(guo)、加拿大(da)、澳大(da)利亞等國(guo)的公(gong)路(lu)建設(she)(she)中(zhong),均采用(yong)(yong)(yong)了(le)(le)鋼(gang)波(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)(guan)進(jin)行(xing)涵(han)(han)洞的施(shi)(shi)工(gong)(gong)。1990年,日本高速公(gong)路(lu)設(she)(she)計(ji),規范制定了(le)(le)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)涵(han)(han)設(she)(she)計(ji)技術規范。隨著鋼(gang)波(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)(guan)在世界各地的安裝(zhuang)使(shi)用(yong)(yong)(yong),證(zheng)明了(le)(le)此(ci)種(zhong)(zhong)結構在各種(zhong)(zhong)使(shi)用(yong)(yong)(yong)情況下的通(tong)用(yong)(yong)(yong)性(xing)。在我國(guo)改革開放(fang)后,深圳及大(da)同煤礦開始(shi)從國(guo)外(wai)進(jin)口成品鋼(gang)波(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)(guan)進(jin)行(xing)涵(han)(han)洞施(shi)(shi)工(gong)(gong)。之后,上海(hai)市公(gong)路(lu)管(guan)(guan)(guan)(guan)(guan)理處、上海(hai)市政工(gong)(gong)程設(she)(she)計(ji)研究院、上海(hai)同濟大(da)學(xue)對(dui)鋼(gang)波(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)(guan)進(jin)行(xing)了(le)(le)動、靜載(zai)試驗,結果表明能滿足設(she)(she)計(ji)使(shi)用(yong)(yong)(yong)要求,填(tian)補了(le)(le)國(guo)內(nei)的空白,且(qie)迅速得到推廣應用(yong)(yong)(yong)。鋼(gang)波(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)(guan)投入到了(le)(le)青海(hai)公(gong)路(lu)施(shi)(shi)工(gong)(gong)當(dang)中(zhong),三年的實踐證(zheng)明鋼(gang)波(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)(guan)在北方寒冷地區完全符合公(gong)路(lu)建設(she)(she)當(dang)中(zhong)的涵(han)(han)洞施(shi)(shi)工(gong)(gong)要求。

實(shi)踐證明,用鋼波(bo)紋涵管代替(ti)鋼筋混凝(ning)土進行涵洞(dong)(dong)施工(gong)(gong),無(wu)論從施工(gong)(gong)周期、施工(gong)(gong)造價、環保意義等方面都有其不可(ke)比擬的(de)(de)優越性(xing),且用鋼波(bo)紋涵管進行涵洞(dong)(dong)施工(gong)(gong),可(ke)大大提高道路(lu)行車的(de)(de)舒(shu)適度與安全性(xing),避免道路(lu)中涵洞(dong)(dong)的(de)(de)“錯臺跳車”現形,有利于解(jie)決西北及我國寒冷地(di)區霜凍對砼管涵結構的(de)(de)破壞問題(ti)。

鋼(gang)波紋涵(han)管如(ru)何(he)滿足塑(su)性成(cheng)形的要(yao)求(qiu)?

我們根據金屬變(bian)形(xing)(xing)規律、波(bo)紋管幾何形(xing)(xing)狀、尺寸、精度(du)、成(cheng)(cheng)(cheng)形(xing)(xing)力的(de)(de)(de)大(da)小和(he)波(bo)紋管軸向彈(dan)性回彈(dan)等,設計成(cheng)(cheng)(cheng)形(xing)(xing)模(mo)具。除設計因素之外,波(bo)紋管很大(da)程度(du)上依賴于制造(zao)工藝(yi),的(de)(de)(de)制造(zao)工藝(yi)是提(ti)高波(bo)紋管性能和(he)質(zhi)量的(de)(de)(de)重要保證。 縱縫焊接工藝(yi):縱縫焊接焊縫達(da)到Ⅰ、ⅠⅠ級焊縫標準要求,同時又能滿足塑性成(cheng)(cheng)(cheng)形(xing)(xing)的(de)(de)(de)要求。

成形(xing)模具(ju)的設計(ji) 波紋(wen)(wen)(wen)管(guan)的剛(gang)度(du)計(ji)算,波紋(wen)(wen)(wen)管(guan)的剛(gang)度(du)按照載(zai)荷(he)及位移性(xing)質不(bu)同(tong),分為軸(zhou)向(xiang)剛(gang)度(du)、彎曲(qu)剛(gang)度(du)、扭(niu)轉剛(gang)度(du)等。目前在波紋(wen)(wen)(wen)管(guan)的應(ying)用中,絕大多數(shu)的受力(li)情況是(shi)軸(zhou)向(xiang)載(zai)荷(he),位移方式(shi)為線位移。 波紋(wen)(wen)(wen)管(guan)制(zhi)造工藝 波紋(wen)(wen)(wen)管(guan)的幾(ji)何形(xing)狀、尺寸和精度(du)是(shi)由成形(xing)模具(ju)來保證的。

 鋼波紋涵管的(de)剛(gang)(gang)度(du)(du)按(an)載荷(he)與(yu)位移性質不同(tong)可分:為軸向(xiang)剛(gang)(gang)度(du)(du)、彎曲(qu)剛(gang)(gang)度(du)(du)、扭轉(zhuan)剛(gang)(gang)度(du)(du)等(deng)。在目前應(ying)用(yong)中絕大部分是(shi)軸向(xiang)剛(gang)(gang)度(du)(du),因(yin)此主要介紹(shao)軸向(xiang)剛(gang)(gang)度(du)(du)剛(gang)(gang)度(du)(du)K,它是(shi)反(fan)應(ying)波紋(wen)(wen)管(guan)(guan)(guan)敏感性的(de)一個參數(shu)。剛(gang)(gang)度(du)(du)越大.敏感性越差,它與(yu)靈敏度(du)(du)δ互(hu)成倒(dao)數(shu)即K=1/δ另外,剛(gang)(gang)度(du)(du)K與(yu)波數(shu)n成反(fan)比。多層管(guan)(guan)(guan)制(zhi)造工(gong)(gong)藝:研究(jiu)套管(guan)(guan)(guan)間隙(xi)和(he)加力方(fang)式,設計專用(yong)工(gong)(gong)裝(zhuang)夾(jia)具消除(chu)套管(guan)(guan)(guan)間隙(xi)。 公路(lu)工(gong)(gong)程的(de)涵(han)(han)洞一般采(cai)用(yong)金(jin)(jin)(jin)屬(shu)筋(jin)(jin)混(hun)凝(ning)土制(zhi)作。現采(cai)用(yong)金(jin)(jin)(jin)屬(shu)波紋(wen)(wen)管(guan)(guan)(guan)涵(han)(han)代(dai)(dai)替金(jin)(jin)(jin)屬(shu)筋(jin)(jin)混(hun)凝(ning)土進行涵(han)(han)洞施工(gong)(gong)在國內時一項新技術,金(jin)(jin)(jin)屬(shu)波紋(wen)(wen)管(guan)(guan)(guan)涵(han)(han)以其性能穩定、安裝(zhuang)方(fang)便、有利環保(bao)、造價低等(deng)優點(dian)迅(xun)速在公路(lu)施工(gong)(gong)中代(dai)(dai)替了金(jin)(jin)(jin)屬(shu)筋(jin)(jin)混(hun)凝(ning)土施工(gong)(gong)的(de)涵(han)(han)洞,發(fa)展前景(jing)非常廣闊。

鋼(gang)(gang)波(bo)(bo)紋(wen)(wen)涵(han)管是將薄鋼(gang)(gang)板(ban)板(ban)面壓成波(bo)(bo)紋(wen)(wen)后,卷制(zhi)成管節(jie),可以增加管節(jie)的剛度(du)和(he)對(dui)管軸壓力(li)的抵抗強度(du);出廠前采用熱(re)浸鍍(du)鋅工藝和(he)施工現場噴涂(tu)瀝青,雙層防腐(fu)處理保證了使用壽命(ming);用此種管節(jie)修建的涵(han)洞被稱為波(bo)(bo)紋(wen)(wen)鋼(gang)(gang)涵(han)管。

隨(sui)著(zhu)波(bo)紋(wen)涵管(guan)在(zai)世界各地的安裝(zhuang)使(shi)用(yong)(yong),證明了(le)此種結(jie)構(gou)在(zai)各種使(shi)用(yong)(yong)情況下(xia)的通(tong)用(yong)(yong)性。在(zai)我國(guo)改革開(kai)放后,深圳(zhen)及大(da)同(tong)煤礦開(kai)始從(cong)國(guo)外進口成品波(bo)紋(wen)涵管(guan)進行涵洞(dong)施工(gong)。之后,上海(hai)市公路管(guan)理處、上海(hai)市政工(gong)程設計研究院、上海(hai)同(tong)濟大(da)學(xue)對(dui)鋼波(bo)紋(wen)涵管(guan)進行了(le)動、靜(jing)載試(shi)驗,結(jie)果表明能滿(man)足設計使(shi)用(yong)(yong)要(yao)求,填(tian)補了(le)國(guo)內的空白,且迅速得到推廣(guang)應用(yong)(yong)。

工作溫(wen)度(du)也(ye)是(shi)影(ying)響(xiang)波紋(wen)管(guan)壽(shou)(shou)命的主(zhu)要因(yin)素之(zhi)(zhi)一。本表所列波紋(wen)管(guan)工作溫(wen)度(du)適(shi)用于溫(wen)度(du)范(fan)圍在(zai)一196℃~600℃之(zhi)(zhi)間(jian)。但即(ji)使在(zai)此范(fan)圍,溫(wen)度(du)越趨(qu)近于兩端其壽(shou)(shou)命也(ye)是(shi)要大(da)打(da)折扣的。因(yin)此若工作溫(wen)度(du)有更高(gao)要求,則(ze)須更換新材料,否則(ze)將嚴重影(ying)響(xiang)產(chan)品(pin)壽(shou)(shou)命。

實(shi)踐證(zheng)明,用(yong)鋼波紋涵(han)管代替(ti)鋼筋混凝土進行(xing)(xing)涵(han)洞(dong)施工,無論(lun)從施工周(zhou)期(qi)、施工造價、環保意義等方面都有其不可比擬的(de)優越性,且(qie)用(yong)鋼波紋涵(han)管進行(xing)(xing)涵(han)洞(dong)施工,可大大提高道路行(xing)(xing)車(che)的(de)舒適(shi)度與(yu)安全(quan)性,避免道路中(zhong)涵(han)洞(dong)的(de)“錯臺跳車(che)”現形,有利于解決(jue)西(xi)北地(di)區寒冷霜凍對砼涵(han)管結(jie)構的(de)破壞問題。

幕墻一(yi)貫反應(ying)(ying)用于我國各地公路設(she)(she)(she)施(shi)建設(she)(she)(she)當中(zhong)。鋼(gang)波紋涵(han)管(guan)投入(ru)到(dao)了青海公路施(shi)工當中(zhong),三年的實踐證明,鋼(gang)波紋涵(han)管(guan)在(zai)北方寒冷地區完全符合公路建設(she)(she)(she)當中(zhong)的涵(han)洞施(shi)工要求。 波紋管(guan)設(she)(she)(she)計計算的參數為剛度、應(ying)(ying)力(li)、有效面(mian)積、失穩(wen)、允許位(wei)移(yi)、耐(nai)壓力(li)和使用壽命。

在公路施工中,應用鋼波紋涵管代替鋼筋混凝土進行涵洞施工的歷史已經有100多年了。1896年,美國率行波紋涵管通道、涵管的可行性研究。其后,在美國、加拿大、澳大利亞等國的公路建設中,均采用了鋼波紋涵管進行涵洞的施工。//hanihanbj.com/
