鋼波紋涵管

鋼波紋管結構在各種使用情況下的通用性強

在公路(lu)施(shi)工(gong)中,應用鋼(gang)波(bo)紋(wen)管(guan)涵(han)(han)(han)(han)代替鋼(gang)筋混凝土進行(xing)涵(han)(han)(han)(han)洞(dong)施(shi)工(gong)的(de)歷史已經有100多(duo)年(nian)了。1896年(nian),美國率提高(gao)前輩行(xing)鋼(gang)波(bo)紋(wen)管(guan)涵(han)(han)(han)(han)通道(dao)、涵(han)(han)(han)(han)管(guan)的(de)可行(xing)性研究。其后,在美國、加(jia)拿大(da)、澳大(da)利(li)亞等(deng)國的(de)公路(lu)建(jian)設中,均采用了鋼(gang)波(bo)紋(wen)管(guan)涵(han)(han)(han)(han)進行(xing)涵(han)(han)(han)(han)洞(dong)的(de)施(shi)工(gong)。1990年(nian),日本(ben)高(gao)速公路(lu)設計(ji),規(gui)(gui)范(fan)(fan)制定(ding)了鋼(gang)波(bo)紋(wen)管(guan)涵(han)(han)(han)(han)設計(ji)技(ji)術規(gui)(gui)范(fan)(fan)。

公路(lu)工(gong)(gong)程的涵(han)洞一般采用鋼(gang)(gang)(gang)筋混(hun)凝土(tu)制作。現采用鋼(gang)(gang)(gang)波紋管涵(han)代替鋼(gang)(gang)(gang)筋混(hun)凝土(tu)進行(xing)涵(han)洞施(shi)工(gong)(gong)在海內時一項新技術(shu),鋼(gang)(gang)(gang)波紋管涵(han)以其機能(neng)不(bu)亂、安裝利(li)便、有利(li)環保、造價低等長處迅速(su)在公路(lu)施(shi)工(gong)(gong)中(zhong)代替了鋼(gang)(gang)(gang)筋混(hun)凝土(tu)施(shi)工(gong)(gong)的涵(han)洞,發展遠景(jing)非常廣闊(kuo)。

拼裝鋼波(bo)(bo)紋管(guan)(guan)(guan)是將(jiang)薄(bo)鋼板(ban)板(ban)面(mian)壓成波(bo)(bo)紋后,卷(juan)制成管(guan)(guan)(guan)節,可以(yi)增(zeng)加管(guan)(guan)(guan)節的剛度和對(dui)管(guan)(guan)(guan)軸壓力的抵擋(dang)強度;出廠前采用(yong)(yong)熱浸(jin)鍍鋅工(gong)(gong)藝和施工(gong)(gong)現場噴涂瀝青,雙層防腐處(chu)理保證了使用(yong)(yong)壽命;用(yong)(yong)此種管(guan)(guan)(guan)節修建的涵(han)(han)洞(dong)被稱為鋼波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)。實(shi)踐(jian)證實(shi),用(yong)(yong)鋼波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)代替(ti)鋼筋(jin)混凝土進行(xing)(xing)涵(han)(han)洞(dong)施工(gong)(gong),不管(guan)(guan)(guan)從施工(gong)(gong)周期、施工(gong)(gong)造價、環保意(yi)義等(deng)方面(mian)都有其不可相比的優(you)勝性,且用(yong)(yong)鋼波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)進行(xing)(xing)涵(han)(han)洞(dong)施工(gong)(gong),可大(da)大(da)進步道(dao)路行(xing)(xing)車的恬靜度與安全(quan)性,避免道(dao)路中涵(han)(han)洞(dong)的“錯臺跳車”現形,有利于(yu)解決西北地區嚴寒霜凍(dong)對(dui)砼管(guan)(guan)(guan)涵(han)(han)結構的破(po)壞題目。
