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)洞一般采(cai)用金(jin)(jin)屬筋(jin)混(hun)凝土(tu)(tu)(tu)制作。現采(cai)用金(jin)(jin)屬波(bo)(bo)(bo)(bo)紋(wen)管(guan)涵(han)代替金(jin)(jin)屬筋(jin)混(hun)凝土(tu)(tu)(tu)進行(xing)(xing)涵(han)洞施(shi)(shi)工(gong)在(zai)(zai)海內時(shi)一項新技(ji)(ji)術,金(jin)(jin)屬波(bo)(bo)(bo)(bo)紋(wen)管(guan)涵(han)以其(qi)機能(neng)不(bu)亂、安(an)裝利(li)便、有利(li)環保、造價低等長(chang)處迅速在(zai)(zai)公(gong)路(lu)施(shi)(shi)工(gong)中代替了(le)(le)金(jin)(jin)屬筋(jin)混(hun)凝土(tu)(tu)(tu)施(shi)(shi)工(gong)的(de)涵(han)洞,發展遠景(jing)非常廣闊。在(zai)(zai)公(gong)路(lu)施(shi)(shi)工(gong)中,應用金(jin)(jin)屬波(bo)(bo)(bo)(bo)紋(wen)管(guan)涵(han)代替金(jin)(jin)屬筋(jin)混(hun)凝土(tu)(tu)(tu)進行(xing)(xing)涵(han)洞施(shi)(shi)工(gong)的(de)歷(li)史已經有100多年了(le)(le)。1896年,美(mei)國(guo)(guo)率(lv)提高前輩行(xing)(xing)波(bo)(bo)(bo)(bo)紋(wen)管(guan)涵(han)通道(dao)、涵(han)管(guan)的(de)可行(xing)(xing)性(xing)研究。其(qi)后,在(zai)(zai)美(mei)國(guo)(guo)、加拿大、澳大利(li)亞(ya)等國(guo)(guo)的(de)公(gong)路(lu)建設中,均采(cai)用了(le)(le)金(jin)(jin)屬波(bo)(bo)(bo)(bo)紋(wen)管(guan)涵(han)進行(xing)(xing)涵(han)洞的(de)施(shi)(shi)工(gong)。1990年,日(ri)本高速公(gong)路(lu)設計(ji),規(gui)范(fan)制定了(le)(le)波(bo)(bo)(bo)(bo)紋(wen)管(guan)涵(han)設計(ji)技(ji)(ji)術規(gui)范(fan)。  

金(jin)(jin)屬波紋(wen)(wen)管(guan)(guan)涵(han)(han)(han)是將薄金(jin)(jin)屬板板面壓成波紋(wen)(wen)后,卷制成管(guan)(guan)節(jie),可以增加管(guan)(guan)節(jie)的剛度和對管(guan)(guan)軸(zhou)壓力的抵擋強(qiang)度;出廠前采用(yong)熱浸鍍鋅工藝和施工現場噴涂瀝青,雙層防腐處理保(bao)證(zheng)了使用(yong)壽命;用(yong)此種管(guan)(guan)節(jie)修建的涵(han)(han)(han)洞被稱為波紋(wen)(wen)金(jin)(jin)屬管(guan)(guan)涵(han)(han)(han)。實踐(jian)證(zheng)實,用(yong)金(jin)(jin)屬波紋(wen)(wen)管(guan)(guan)涵(han)(han)(han)代替金(jin)(jin)屬筋混(hun)凝土進(jin)行涵(han)(han)(han)洞施工,不管(guan)(guan)從施工周期、施工造價、環保(bao)意(yi)義等方面都有其不可相比(bi)的優勝性(xing),且用(yong)金(jin)(jin)屬波紋(wen)(wen)管(guan)(guan)涵(han)(han)(han)進(jin)行涵(han)(han)(han)洞施工,可大大進(jin)步道路(lu)行車的恬靜度與安(an)全性(xing),避免道路(lu)中(zhong)涵(han)(han)(han)洞的“錯臺跳車”現形,有利于(yu)解決西北地區嚴寒霜凍對砼管(guan)(guan)涵(han)(han)(han)結構的破壞題(ti)目(mu)。

鋼制波紋涵管

鋼波紋涵管設計計算的(de)(de)參(can)數為(wei)(wei)剛度(du)(du)、應(ying)力、有效面(mian)積、失(shi)穩(wen)、答(da)應(ying)位(wei)移(yi)、耐(nai)壓(ya)力和使用壽命。波紋(wen)(wen)管的(de)(de)剛度(du)(du)計算,波紋(wen)(wen)管的(de)(de)剛度(du)(du)按(an)照(zhao)載荷及位(wei)移(yi)性質不同,分為(wei)(wei)軸向剛度(du)(du)、彎曲剛度(du)(du)、扭轉剛度(du)(du)等。目前在波紋(wen)(wen)管的(de)(de)應(ying)用中,絕(jue)大多(duo)數的(de)(de)受力情況(kuang)是軸向載荷,位(wei)移(yi)方式為(wei)(wei)線位(wei)移(yi)。

根據波紋管的(de)結構(gou)特(te)點(dian),可以把波紋管當作圓(yuan)環殼(ke)、扁錐殼(ke)或圓(yuan)環板所組成(cheng)。設計(ji)(ji)計(ji)(ji)算(suan)波紋管也就是(shi)設計(ji)(ji)計(ji)(ji)算(suan)圓(yuan)外殼(ke)、扁錐殼(ke)或團環板。

金屬波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)設(she)計的理(li)論基礎是板殼理(li)論、材料力學、計算(suan)數學等。波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)設(she)計的參數較多,因(yin)為(wei)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)在系統中的用途(tu)不(bu)同,其(qi)設(she)計計算(suan)的重(zhong)點也不(bu)一(yi)樣。例如(ru),波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)用于(yu)力平衡(heng)元件(jian)(jian),要(yao)求波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)在工作范(fan)圍內其(qi)有(you)效(xiao)面積(ji)不(bu)變或變化很小,用于(yu)丈(zhang)量(liang)元件(jian)(jian),要(yao)求波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)的彈性(xing)特(te)性(xing)是線性(xing)的;用于(yu)真(zhen)空(kong)開關(guan)管(guan)(guan)(guan)作真(zhen)空(kong)密(mi)封(feng)件(jian)(jian),要(yao)求波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)的真(zhen)空(kong)密(mi)封(feng)性(xing)、軸(zhou)向位移(yi)量(liang)和疲憊壽(shou)命(ming);用于(yu)閥門作密(mi)封(feng)件(jian)(jian),要(yao)求波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)應具有(you)一(yi)定的耐(nai)壓力、耐(nai)侵(qin)蝕、耐(nai)溫度(du)、工作位移(yi)和疲憊壽(shou)命(ming)。
