跟著鋼波紋涵管在世界各地的安(an)裝使(shi)用(yong)(yong)(yong),證(zheng)實了此種結構在各種使(shi)用(yong)(yong)(yong)情況下的通用(yong)(yong)(yong)性。在我(wo)國(guo)改革開(kai)放后,深(shen)圳及大(da)同煤礦(kuang)開(kai)始從(cong)國(guo)外入口成品波(bo)(bo)紋(wen)(wen)管涵(han)進(jin)行(xing)涵(han)洞施(shi)工。之后,上(shang)海市公路治理處、上(shang)海市政(zheng)工程設計研究院、上(shang)海同濟大(da)學(xue)對金屬(shu)波(bo)(bo)紋(wen)(wen)管涵(han)進(jin)行(xing)了動、靜載試驗,結果表明(ming)能知足設計使(shi)用(yong)(yong)(yong)要求,填補了海內的空缺,且迅速(su)得到推廣應(ying)用(yong)(yong)(yong)。幕墻(qiang)一貫(guan)反應(ying)用(yong)(yong)(yong)于我(wo)國(guo)各地公路舉措措施(shi)建設當(dang)中。

公(gong)(gong)(gong)路(lu)工程的(de)涵(han)(han)(han)洞一(yi)般采(cai)用(yong)(yong)金(jin)(jin)屬筋混(hun)(hun)凝土制作。現采(cai)用(yong)(yong)金(jin)(jin)屬波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)(han)代替(ti)(ti)金(jin)(jin)屬筋混(hun)(hun)凝土進行(xing)涵(han)(han)(han)洞施(shi)(shi)工在(zai)海內(nei)時一(yi)項(xiang)新技術(shu),金(jin)(jin)屬波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)(han)以其機能不亂、安裝(zhuang)利(li)(li)便、有利(li)(li)環保、造價低等(deng)長處迅速在(zai)公(gong)(gong)(gong)路(lu)施(shi)(shi)工中代替(ti)(ti)了(le)(le)金(jin)(jin)屬筋混(hun)(hun)凝土施(shi)(shi)工的(de)涵(han)(han)(han)洞,發展遠景非(fei)常廣闊。在(zai)公(gong)(gong)(gong)路(lu)施(shi)(shi)工中,應(ying)用(yong)(yong)金(jin)(jin)屬波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)(han)代替(ti)(ti)金(jin)(jin)屬筋混(hun)(hun)凝土進行(xing)涵(han)(han)(han)洞施(shi)(shi)工的(de)歷史已經有100多年(nian)(nian)(nian)了(le)(le)。1896年(nian)(nian)(nian),美(mei)國(guo)(guo)率(lv)提(ti)高前輩(bei)行(xing)波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)(han)通道、涵(han)(han)(han)管(guan)(guan)的(de)可行(xing)性研究。其后(hou),在(zai)美(mei)國(guo)(guo)、加拿(na)大(da)(da)、澳大(da)(da)利(li)(li)亞等(deng)國(guo)(guo)的(de)公(gong)(gong)(gong)路(lu)建設(she)中,均采(cai)用(yong)(yong)了(le)(le)金(jin)(jin)屬波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)(han)進行(xing)涵(han)(han)(han)洞的(de)施(shi)(shi)工。1990年(nian)(nian)(nian),日本高速公(gong)(gong)(gong)路(lu)設(she)計,規范制定了(le)(le)波(bo)(bo)紋(wen)(wen)管(guan)(guan)涵(han)(han)(han)設(she)計技術(shu)規范。  

金(jin)屬(shu)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)涵是將薄(bo)金(jin)屬(shu)板板面壓(ya)(ya)成波(bo)紋(wen)(wen)(wen)后(hou),卷制成管(guan)(guan)(guan)節(jie),可以增加管(guan)(guan)(guan)節(jie)的(de)剛度和(he)對(dui)管(guan)(guan)(guan)軸(zhou)壓(ya)(ya)力的(de)抵擋強度;出(chu)廠前采用(yong)(yong)熱浸(jin)鍍鋅工(gong)(gong)藝和(he)施工(gong)(gong)現(xian)場噴涂瀝青,雙層(ceng)防腐處理保(bao)證了使用(yong)(yong)壽命;用(yong)(yong)此種管(guan)(guan)(guan)節(jie)修建的(de)涵洞(dong)被(bei)稱為(wei)波(bo)紋(wen)(wen)(wen)金(jin)屬(shu)管(guan)(guan)(guan)涵。實(shi)(shi)踐證實(shi)(shi),用(yong)(yong)金(jin)屬(shu)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)涵代替(ti)金(jin)屬(shu)筋(jin)混凝土(tu)進(jin)行涵洞(dong)施工(gong)(gong),不(bu)管(guan)(guan)(guan)從(cong)施工(gong)(gong)周(zhou)期、施工(gong)(gong)造價、環保(bao)意義(yi)等方面都有(you)其不(bu)可相比的(de)優(you)勝性(xing),且(qie)用(yong)(yong)金(jin)屬(shu)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)涵進(jin)行涵洞(dong)施工(gong)(gong),可大大進(jin)步道(dao)路行車(che)的(de)恬靜度與(yu)安全性(xing),避免道(dao)路中涵洞(dong)的(de)“錯臺跳車(che)”現(xian)形,有(you)利于解決西北地區(qu)嚴寒霜凍對(dui)砼管(guan)(guan)(guan)涵結構的(de)破壞題(ti)目。

鋼制波紋涵管

鋼波紋涵管設(she)計計算(suan)的(de)參數為(wei)(wei)剛度、應(ying)力(li)、有效面積、失穩(wen)、答(da)應(ying)位移、耐壓(ya)力(li)和使(shi)用壽命。波紋(wen)管的(de)剛度計算(suan),波紋(wen)管的(de)剛度按照載(zai)荷及位移性質不同,分(fen)為(wei)(wei)軸向剛度、彎曲剛度、扭(niu)轉剛度等。目(mu)前在波紋(wen)管的(de)應(ying)用中,絕大(da)多數的(de)受力(li)情(qing)況是軸向載(zai)荷,位移方式為(wei)(wei)線(xian)位移。

根據波紋(wen)管的結(jie)構(gou)特點,可以(yi)把波紋(wen)管當作(zuo)圓環殼(ke)(ke)(ke)、扁(bian)錐(zhui)殼(ke)(ke)(ke)或圓環板(ban)(ban)所組(zu)成。設(she)計計算波紋(wen)管也就是設(she)計計算圓外殼(ke)(ke)(ke)、扁(bian)錐(zhui)殼(ke)(ke)(ke)或團環板(ban)(ban)。

金屬波(bo)(bo)(bo)紋(wen)管(guan)(guan)設計的(de)(de)理論基礎(chu)是板殼理論、材料力學、計算(suan)數學等。波(bo)(bo)(bo)紋(wen)管(guan)(guan)設計的(de)(de)參數較(jiao)多,因(yin)為波(bo)(bo)(bo)紋(wen)管(guan)(guan)在(zai)系統中的(de)(de)用(yong)(yong)途不同(tong),其(qi)設計計算(suan)的(de)(de)重點也(ye)不一樣。例如,波(bo)(bo)(bo)紋(wen)管(guan)(guan)用(yong)(yong)于力平(ping)衡元(yuan)(yuan)件,要(yao)求(qiu)波(bo)(bo)(bo)紋(wen)管(guan)(guan)在(zai)工(gong)作(zuo)范圍(wei)內(nei)其(qi)有效面積(ji)不變或變化很小,用(yong)(yong)于丈量(liang)元(yuan)(yuan)件,要(yao)求(qiu)波(bo)(bo)(bo)紋(wen)管(guan)(guan)的(de)(de)彈性(xing)特性(xing)是線性(xing)的(de)(de);用(yong)(yong)于真空開關管(guan)(guan)作(zuo)真空密封(feng)件,要(yao)求(qiu)波(bo)(bo)(bo)紋(wen)管(guan)(guan)的(de)(de)真空密封(feng)性(xing)、軸向位(wei)移(yi)(yi)量(liang)和疲(pi)憊壽命;用(yong)(yong)于閥門作(zuo)密封(feng)件,要(yao)求(qiu)波(bo)(bo)(bo)紋(wen)管(guan)(guan)應(ying)具(ju)有一定的(de)(de)耐壓力、耐侵蝕、耐溫度、工(gong)作(zuo)位(wei)移(yi)(yi)和疲(pi)憊壽命。
