跟著鋼波紋涵管在世界各地的(de)安裝使用(yong),證(zheng)實(shi)了(le)此(ci)種(zhong)結構在各種(zhong)使用(yong)情(qing)況下的(de)通用(yong)性。在我國(guo)改革開放后(hou),深(shen)圳(zhen)及大同煤(mei)礦開始從國(guo)外入口(kou)成品波(bo)紋(wen)管涵(han)進行(xing)涵(han)洞(dong)施工。之后(hou),上海(hai)(hai)市公(gong)路(lu)治(zhi)理處、上海(hai)(hai)市政工程設(she)計(ji)研究院、上海(hai)(hai)同濟大學對金(jin)屬波(bo)紋(wen)管涵(han)進行(xing)了(le)動、靜載試驗,結果表(biao)明能知(zhi)足設(she)計(ji)使用(yong)要(yao)求,填補了(le)海(hai)(hai)內(nei)的(de)空(kong)缺,且迅速得到推(tui)廣應用(yong)。幕墻一貫反應用(yong)于我國(guo)各地公(gong)路(lu)舉措(cuo)措(cuo)施建設(she)當中。

近些年鋼波紋涵管在世界范圍內高速發展

公(gong)路(lu)工(gong)程的(de)涵(han)(han)洞(dong)一(yi)般采(cai)用(yong)金(jin)(jin)屬(shu)(shu)筋(jin)混(hun)凝(ning)土(tu)制作(zuo)。現采(cai)用(yong)金(jin)(jin)屬(shu)(shu)波(bo)紋(wen)(wen)管涵(han)(han)代替(ti)金(jin)(jin)屬(shu)(shu)筋(jin)混(hun)凝(ning)土(tu)進行(xing)涵(han)(han)洞(dong)施(shi)工(gong)在海(hai)內時一(yi)項新技術,金(jin)(jin)屬(shu)(shu)波(bo)紋(wen)(wen)管涵(han)(han)以其機能不(bu)亂(luan)、安裝(zhuang)利便、有利環保、造價低等(deng)長處迅(xun)速(su)在公(gong)路(lu)施(shi)工(gong)中(zhong)(zhong)代替(ti)了(le)金(jin)(jin)屬(shu)(shu)筋(jin)混(hun)凝(ning)土(tu)施(shi)工(gong)的(de)涵(han)(han)洞(dong),發展遠景非常(chang)廣闊。在公(gong)路(lu)施(shi)工(gong)中(zhong)(zhong),應用(yong)金(jin)(jin)屬(shu)(shu)波(bo)紋(wen)(wen)管涵(han)(han)代替(ti)金(jin)(jin)屬(shu)(shu)筋(jin)混(hun)凝(ning)土(tu)進行(xing)涵(han)(han)洞(dong)施(shi)工(gong)的(de)歷史已經有100多年(nian)了(le)。1896年(nian),美(mei)國(guo)(guo)率提(ti)高前(qian)輩行(xing)波(bo)紋(wen)(wen)管涵(han)(han)通道(dao)、涵(han)(han)管的(de)可行(xing)性(xing)研(yan)究(jiu)。其后,在美(mei)國(guo)(guo)、加(jia)拿大、澳大利亞等(deng)國(guo)(guo)的(de)公(gong)路(lu)建(jian)設中(zhong)(zhong),均(jun)采(cai)用(yong)了(le)金(jin)(jin)屬(shu)(shu)波(bo)紋(wen)(wen)管涵(han)(han)進行(xing)涵(han)(han)洞(dong)的(de)施(shi)工(gong)。1990年(nian),日本(ben)高速(su)公(gong)路(lu)設計(ji),規范制定了(le)波(bo)紋(wen)(wen)管涵(han)(han)設計(ji)技術規范。  

金屬(shu)(shu)(shu)波紋(wen)管(guan)(guan)(guan)(guan)涵是將薄(bo)金屬(shu)(shu)(shu)板(ban)板(ban)面壓成波紋(wen)后,卷制成管(guan)(guan)(guan)(guan)節,可(ke)以(yi)增加管(guan)(guan)(guan)(guan)節的剛度和對(dui)(dui)管(guan)(guan)(guan)(guan)軸壓力的抵擋強(qiang)度;出廠前采(cai)用(yong)熱浸鍍鋅工(gong)(gong)藝和施工(gong)(gong)現場噴涂瀝(li)青,雙層防腐處理保證了使用(yong)壽(shou)命(ming);用(yong)此(ci)種管(guan)(guan)(guan)(guan)節修建的涵洞(dong)被(bei)稱為波紋(wen)金屬(shu)(shu)(shu)管(guan)(guan)(guan)(guan)涵。實(shi)踐(jian)證實(shi),用(yong)金屬(shu)(shu)(shu)波紋(wen)管(guan)(guan)(guan)(guan)涵代替金屬(shu)(shu)(shu)筋混凝(ning)土進行涵洞(dong)施工(gong)(gong),不管(guan)(guan)(guan)(guan)從施工(gong)(gong)周期、施工(gong)(gong)造(zao)價、環保意(yi)義等方面都(dou)有其(qi)不可(ke)相比(bi)的優(you)勝性,且用(yong)金屬(shu)(shu)(shu)波紋(wen)管(guan)(guan)(guan)(guan)涵進行涵洞(dong)施工(gong)(gong),可(ke)大(da)大(da)進步道(dao)路行車的恬靜度與安全性,避免道(dao)路中涵洞(dong)的“錯臺跳車”現形,有利(li)于解(jie)決西北地區嚴寒霜凍對(dui)(dui)砼管(guan)(guan)(guan)(guan)涵結構的破壞題目。

鋼制波紋涵管

鋼波紋涵管設計(ji)計(ji)算(suan)的(de)(de)參數為(wei)剛(gang)度、應(ying)力、有(you)效面(mian)積(ji)、失穩、答應(ying)位移、耐壓力和(he)使(shi)用(yong)壽命。波(bo)紋管(guan)(guan)(guan)的(de)(de)剛(gang)度計(ji)算(suan),波(bo)紋管(guan)(guan)(guan)的(de)(de)剛(gang)度按照載荷及位移性質不同,分(fen)為(wei)軸(zhou)向(xiang)剛(gang)度、彎曲(qu)剛(gang)度、扭轉剛(gang)度等。目前在波(bo)紋管(guan)(guan)(guan)的(de)(de)應(ying)用(yong)中(zhong),絕大多數的(de)(de)受(shou)力情況是軸(zhou)向(xiang)載荷,位移方(fang)式為(wei)線(xian)位移。

根(gen)據波紋管的結(jie)構特點,可以把波紋管當作圓環(huan)(huan)殼、扁錐殼或圓環(huan)(huan)板所組成。設(she)計(ji)計(ji)算波紋管也就是設(she)計(ji)計(ji)算圓外殼、扁錐殼或團(tuan)環(huan)(huan)板。

金(jin)屬波(bo)(bo)紋(wen)(wen)管(guan)(guan)設(she)計(ji)的(de)(de)理論(lun)基(ji)礎(chu)是板殼(ke)理論(lun)、材料力學、計(ji)算(suan)(suan)數學等。波(bo)(bo)紋(wen)(wen)管(guan)(guan)設(she)計(ji)的(de)(de)參(can)數較多,因為波(bo)(bo)紋(wen)(wen)管(guan)(guan)在系統中的(de)(de)用(yong)途(tu)不同,其設(she)計(ji)計(ji)算(suan)(suan)的(de)(de)重點也不一(yi)樣(yang)。例如(ru),波(bo)(bo)紋(wen)(wen)管(guan)(guan)用(yong)于(yu)力平衡元件,要(yao)求波(bo)(bo)紋(wen)(wen)管(guan)(guan)在工作范圍內其有效面積不變或(huo)變化(hua)很小,用(yong)于(yu)丈量元件,要(yao)求波(bo)(bo)紋(wen)(wen)管(guan)(guan)的(de)(de)彈性特性是線性的(de)(de);用(yong)于(yu)真(zhen)(zhen)空開關管(guan)(guan)作真(zhen)(zhen)空密(mi)封件,要(yao)求波(bo)(bo)紋(wen)(wen)管(guan)(guan)的(de)(de)真(zhen)(zhen)空密(mi)封性、軸向位(wei)移量和(he)疲憊壽命(ming)(ming);用(yong)于(yu)閥門(men)作密(mi)封件,要(yao)求波(bo)(bo)紋(wen)(wen)管(guan)(guan)應具有一(yi)定(ding)的(de)(de)耐壓力、耐侵蝕、耐溫度、工作位(wei)移和(he)疲憊壽命(ming)(ming)。
