近些年鋼波紋涵管在世界范圍內高速發展

公路工(gong)程的(de)涵(han)(han)(han)(han)(han)(han)洞一般采用金屬(shu)筋(jin)混(hun)(hun)(hun)凝(ning)土(tu)制作(zuo)。現(xian)采用金屬(shu)波紋(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)(han)(han)(han)代(dai)替(ti)金屬(shu)筋(jin)混(hun)(hun)(hun)凝(ning)土(tu)進(jin)行(xing)涵(han)(han)(han)(han)(han)(han)洞施(shi)工(gong)在(zai)海內時(shi)一項新技術,金屬(shu)波紋(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)(han)(han)(han)以(yi)其機能不亂、安裝利便、有(you)利環保、造價(jia)低等(deng)長處迅速在(zai)公路施(shi)工(gong)中代(dai)替(ti)了(le)金屬(shu)筋(jin)混(hun)(hun)(hun)凝(ning)土(tu)施(shi)工(gong)的(de)涵(han)(han)(han)(han)(han)(han)洞,發展遠景非常廣闊。在(zai)公路施(shi)工(gong)中,應用金屬(shu)波紋(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)(han)(han)(han)代(dai)替(ti)金屬(shu)筋(jin)混(hun)(hun)(hun)凝(ning)土(tu)進(jin)行(xing)涵(han)(han)(han)(han)(han)(han)洞施(shi)工(gong)的(de)歷史已經有(you)100多年(nian)了(le)。1896年(nian),美國(guo)(guo)率提高前輩行(xing)波紋(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)(han)(han)(han)通道(dao)、涵(han)(han)(han)(han)(han)(han)管(guan)(guan)(guan)的(de)可行(xing)性研究(jiu)。其后,在(zai)美國(guo)(guo)、加拿大、澳大利亞等(deng)國(guo)(guo)的(de)公路建設中,均采用了(le)金屬(shu)波紋(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)(han)(han)(han)進(jin)行(xing)涵(han)(han)(han)(han)(han)(han)洞的(de)施(shi)工(gong)。1990年(nian),日(ri)本高速公路設計(ji),規范制定了(le)波紋(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)(han)(han)(han)設計(ji)技術規范。  

金屬(shu)(shu)波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)(han)是將薄金屬(shu)(shu)板板面壓成波(bo)(bo)紋后,卷制成管(guan)(guan)(guan)節,可(ke)以(yi)增加管(guan)(guan)(guan)節的(de)(de)(de)剛度(du)和對管(guan)(guan)(guan)軸壓力的(de)(de)(de)抵擋強度(du);出(chu)廠前采(cai)用(yong)(yong)熱浸鍍鋅工(gong)藝(yi)和施(shi)(shi)(shi)工(gong)現(xian)場噴涂瀝青,雙層防腐處理保(bao)證了使用(yong)(yong)壽命;用(yong)(yong)此種(zhong)管(guan)(guan)(guan)節修建的(de)(de)(de)涵(han)(han)(han)洞(dong)被稱為波(bo)(bo)紋金屬(shu)(shu)管(guan)(guan)(guan)涵(han)(han)(han)。實(shi)踐證實(shi),用(yong)(yong)金屬(shu)(shu)波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)(han)代替金屬(shu)(shu)筋混凝(ning)土進行(xing)涵(han)(han)(han)洞(dong)施(shi)(shi)(shi)工(gong),不管(guan)(guan)(guan)從施(shi)(shi)(shi)工(gong)周期(qi)、施(shi)(shi)(shi)工(gong)造價、環保(bao)意義等方(fang)面都有其不可(ke)相(xiang)比的(de)(de)(de)優勝性,且用(yong)(yong)金屬(shu)(shu)波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)(han)進行(xing)涵(han)(han)(han)洞(dong)施(shi)(shi)(shi)工(gong),可(ke)大(da)大(da)進步(bu)道(dao)路(lu)行(xing)車的(de)(de)(de)恬靜度(du)與安(an)全(quan)性,避免道(dao)路(lu)中涵(han)(han)(han)洞(dong)的(de)(de)(de)“錯臺(tai)跳車”現(xian)形(xing),有利(li)于解決西北地區嚴寒霜凍對砼管(guan)(guan)(guan)涵(han)(han)(han)結(jie)構的(de)(de)(de)破壞題目。

鋼制波紋涵管

鋼波紋涵管設(she)計(ji)計(ji)算的(de)參數(shu)(shu)為(wei)剛(gang)度(du)、應力、有效面積、失穩、答(da)應位(wei)移、耐壓(ya)力和使用壽(shou)命(ming)。波(bo)紋管(guan)的(de)剛(gang)度(du)計(ji)算,波(bo)紋管(guan)的(de)剛(gang)度(du)按照載荷及位(wei)移性質不(bu)同,分為(wei)軸向(xiang)剛(gang)度(du)、彎曲剛(gang)度(du)、扭轉剛(gang)度(du)等。目(mu)前(qian)在波(bo)紋管(guan)的(de)應用中,絕大(da)多數(shu)(shu)的(de)受(shou)力情況(kuang)是軸向(xiang)載荷,位(wei)移方式為(wei)線位(wei)移。

根據波(bo)紋管(guan)(guan)的(de)結構特(te)點,可以把(ba)波(bo)紋管(guan)(guan)當(dang)作圓環(huan)殼(ke)、扁錐(zhui)殼(ke)或(huo)圓環(huan)板所(suo)組(zu)成(cheng)。設(she)計(ji)計(ji)算波(bo)紋管(guan)(guan)也就是設(she)計(ji)計(ji)算圓外(wai)殼(ke)、扁錐(zhui)殼(ke)或(huo)團環(huan)板。

金屬波(bo)紋(wen)(wen)管(guan)設計(ji)(ji)的(de)理論(lun)基礎是板殼(ke)理論(lun)、材料力(li)學(xue)、計(ji)(ji)算數學(xue)等。波(bo)紋(wen)(wen)管(guan)設計(ji)(ji)的(de)參數較多,因為波(bo)紋(wen)(wen)管(guan)在(zai)系統中(zhong)的(de)用(yong)途不(bu)(bu)同,其設計(ji)(ji)計(ji)(ji)算的(de)重(zhong)點也不(bu)(bu)一(yi)樣。例如,波(bo)紋(wen)(wen)管(guan)用(yong)于力(li)平衡元件(jian),要求波(bo)紋(wen)(wen)管(guan)在(zai)工(gong)作(zuo)(zuo)范圍內其有(you)效面積不(bu)(bu)變(bian)(bian)或變(bian)(bian)化很(hen)小,用(yong)于丈(zhang)量元件(jian),要求波(bo)紋(wen)(wen)管(guan)的(de)彈性特性是線性的(de);用(yong)于真空開關管(guan)作(zuo)(zuo)真空密封件(jian),要求波(bo)紋(wen)(wen)管(guan)的(de)真空密封性、軸(zhou)向位(wei)移量和疲憊壽(shou)命;用(yong)于閥(fa)門作(zuo)(zuo)密封件(jian),要求波(bo)紋(wen)(wen)管(guan)應具有(you)一(yi)定的(de)耐壓力(li)、耐侵蝕、耐溫度、工(gong)作(zuo)(zuo)位(wei)移和疲憊壽(shou)命。
