近些年鋼波紋涵管在世界范圍內高速發展

公(gong)路(lu)工程的(de)(de)涵(han)(han)(han)(han)洞(dong)一般采用(yong)金(jin)(jin)屬(shu)筋混(hun)凝(ning)土(tu)(tu)制(zhi)作。現采用(yong)金(jin)(jin)屬(shu)波(bo)紋(wen)(wen)管(guan)涵(han)(han)(han)(han)代(dai)替金(jin)(jin)屬(shu)筋混(hun)凝(ning)土(tu)(tu)進(jin)行(xing)涵(han)(han)(han)(han)洞(dong)施工在海內時一項新技(ji)術(shu),金(jin)(jin)屬(shu)波(bo)紋(wen)(wen)管(guan)涵(han)(han)(han)(han)以其機能不亂(luan)、安(an)裝利便、有利環保、造價(jia)低等長(chang)處迅速在公(gong)路(lu)施工中(zhong)代(dai)替了(le)金(jin)(jin)屬(shu)筋混(hun)凝(ning)土(tu)(tu)施工的(de)(de)涵(han)(han)(han)(han)洞(dong),發展遠景非常廣闊。在公(gong)路(lu)施工中(zhong),應用(yong)金(jin)(jin)屬(shu)波(bo)紋(wen)(wen)管(guan)涵(han)(han)(han)(han)代(dai)替金(jin)(jin)屬(shu)筋混(hun)凝(ning)土(tu)(tu)進(jin)行(xing)涵(han)(han)(han)(han)洞(dong)施工的(de)(de)歷史(shi)已(yi)經有100多年(nian)(nian)了(le)。1896年(nian)(nian),美(mei)國(guo)率提高(gao)(gao)前輩(bei)行(xing)波(bo)紋(wen)(wen)管(guan)涵(han)(han)(han)(han)通(tong)道、涵(han)(han)(han)(han)管(guan)的(de)(de)可行(xing)性研究(jiu)。其后,在美(mei)國(guo)、加(jia)拿大、澳大利亞(ya)等國(guo)的(de)(de)公(gong)路(lu)建設中(zhong),均采用(yong)了(le)金(jin)(jin)屬(shu)波(bo)紋(wen)(wen)管(guan)涵(han)(han)(han)(han)進(jin)行(xing)涵(han)(han)(han)(han)洞(dong)的(de)(de)施工。1990年(nian)(nian),日本高(gao)(gao)速公(gong)路(lu)設計,規范(fan)制(zhi)定(ding)了(le)波(bo)紋(wen)(wen)管(guan)涵(han)(han)(han)(han)設計技(ji)術(shu)規范(fan)。  

金(jin)屬(shu)(shu)(shu)(shu)波紋管(guan)涵(han)(han)(han)(han)是將薄金(jin)屬(shu)(shu)(shu)(shu)板(ban)板(ban)面(mian)壓成波紋后,卷制(zhi)成管(guan)節,可以增(zeng)加管(guan)節的剛度(du)和(he)對管(guan)軸壓力的抵擋強度(du);出(chu)廠前采用(yong)熱(re)浸鍍鋅工(gong)藝和(he)施(shi)工(gong)現(xian)(xian)場(chang)噴涂瀝青,雙(shuang)層防腐(fu)處理保證了使(shi)用(yong)壽命;用(yong)此種管(guan)節修(xiu)建的涵(han)(han)(han)(han)洞(dong)(dong)被(bei)稱為波紋金(jin)屬(shu)(shu)(shu)(shu)管(guan)涵(han)(han)(han)(han)。實踐(jian)證實,用(yong)金(jin)屬(shu)(shu)(shu)(shu)波紋管(guan)涵(han)(han)(han)(han)代(dai)替(ti)金(jin)屬(shu)(shu)(shu)(shu)筋混凝土進(jin)行(xing)涵(han)(han)(han)(han)洞(dong)(dong)施(shi)工(gong),不管(guan)從(cong)施(shi)工(gong)周期、施(shi)工(gong)造價(jia)、環保意(yi)義等方(fang)面(mian)都有(you)其不可相比的優勝性,且用(yong)金(jin)屬(shu)(shu)(shu)(shu)波紋管(guan)涵(han)(han)(han)(han)進(jin)行(xing)涵(han)(han)(han)(han)洞(dong)(dong)施(shi)工(gong),可大(da)(da)大(da)(da)進(jin)步道(dao)路行(xing)車的恬靜度(du)與安全性,避免道(dao)路中涵(han)(han)(han)(han)洞(dong)(dong)的“錯(cuo)臺跳車”現(xian)(xian)形,有(you)利于(yu)解決西北地區嚴寒(han)霜凍對砼管(guan)涵(han)(han)(han)(han)結(jie)構(gou)的破壞題目。

鋼制波紋涵管

鋼波紋涵管設(she)計(ji)計(ji)算(suan)的參數為剛度(du)(du)、應(ying)力(li)(li)、有效(xiao)面(mian)積、失穩、答應(ying)位(wei)移、耐壓力(li)(li)和使用壽(shou)命。波(bo)紋管(guan)的剛度(du)(du)計(ji)算(suan),波(bo)紋管(guan)的剛度(du)(du)按(an)照載荷及位(wei)移性質不(bu)同(tong),分為軸(zhou)向剛度(du)(du)、彎曲剛度(du)(du)、扭轉剛度(du)(du)等(deng)。目前在波(bo)紋管(guan)的應(ying)用中,絕大多數的受力(li)(li)情況是軸(zhou)向載荷,位(wei)移方(fang)式(shi)為線位(wei)移。

根據波(bo)(bo)紋管的結構特點,可以把(ba)波(bo)(bo)紋管當作(zuo)圓環殼、扁(bian)錐(zhui)(zhui)殼或圓環板所組成。設計計算波(bo)(bo)紋管也(ye)就是設計計算圓外殼、扁(bian)錐(zhui)(zhui)殼或團(tuan)環板。

金(jin)屬(shu)波(bo)(bo)(bo)紋(wen)(wen)管(guan)設計(ji)(ji)的(de)理論(lun)基礎是板殼理論(lun)、材(cai)料力(li)學、計(ji)(ji)算(suan)數學等。波(bo)(bo)(bo)紋(wen)(wen)管(guan)設計(ji)(ji)的(de)參(can)數較多,因(yin)為(wei)波(bo)(bo)(bo)紋(wen)(wen)管(guan)在系(xi)統中的(de)用(yong)(yong)途不同,其(qi)(qi)設計(ji)(ji)計(ji)(ji)算(suan)的(de)重點也(ye)不一(yi)樣(yang)。例如(ru),波(bo)(bo)(bo)紋(wen)(wen)管(guan)用(yong)(yong)于(yu)力(li)平衡元件,要(yao)求波(bo)(bo)(bo)紋(wen)(wen)管(guan)在工作范圍內其(qi)(qi)有(you)(you)效面積(ji)不變或變化很小,用(yong)(yong)于(yu)丈(zhang)量(liang)元件,要(yao)求波(bo)(bo)(bo)紋(wen)(wen)管(guan)的(de)彈性特(te)性是線性的(de);用(yong)(yong)于(yu)真(zhen)空(kong)開關管(guan)作真(zhen)空(kong)密封(feng)件,要(yao)求波(bo)(bo)(bo)紋(wen)(wen)管(guan)的(de)真(zhen)空(kong)密封(feng)性、軸向位移量(liang)和疲(pi)憊(bei)壽(shou)命;用(yong)(yong)于(yu)閥門作密封(feng)件,要(yao)求波(bo)(bo)(bo)紋(wen)(wen)管(guan)應具(ju)有(you)(you)一(yi)定(ding)的(de)耐壓力(li)、耐侵蝕、耐溫度、工作位移和疲(pi)憊(bei)壽(shou)命。
