跟著鋼波紋管在世界各地的(de)安裝使用,證實(shi)了此種結構在各種使用情況(kuang)下的(de)通(tong)用性。在我國改革開(kai)放后(hou),深圳及大同(tong)煤礦開(kai)始(shi)從國外入(ru)口成品鋼(gang)(gang)波紋(wen)管(guan)(guan)涵進(jin)(jin)行(xing)涵洞施工。之(zhi)后(hou),上海(hai)市公(gong)(gong)路(lu)治理處(chu)、上海(hai)市政工程設計研究院、上海(hai)同(tong)濟(ji)大學對(dui)鋼(gang)(gang)波紋(wen)管(guan)(guan)涵進(jin)(jin)行(xing)了動(dong)、靜載試驗,結果(guo)表明能知足設計使用要求,填補了海(hai)內的(de)空(kong)缺,且(qie)迅速得到推廣應用。幕(mu)墻一貫反應用于我國各地公(gong)(gong)路(lu)舉措(cuo)措(cuo)施建設當中。鋼(gang)(gang)波紋(wen)管(guan)(guan)涵投入(ru)到了青海(hai)公(gong)(gong)路(lu)施工當中,三年的(de)實(shi)踐證實(shi),鋼(gang)(gang)波紋(wen)管(guan)(guan)涵在北方嚴寒地區(qu)完(wan)全符合公(gong)(gong)路(lu)建設當中的(de)涵洞施工要求。
拼接型鋼波紋管快速安裝方法
在公路(lu)施(shi)工中,應用(yong)鋼波(bo)紋管(guan)涵(han)(han)代替鋼筋混凝土進(jin)行(xing)涵(han)(han)洞施(shi)工的歷史已(yi)經有100多年了。1896年,美國率(lv)提高前輩行(xing)鋼波(bo)紋管(guan)涵(han)(han)通道、涵(han)(han)管(guan)的可(ke)行(xing)性研究。其后,在美國、加拿大、澳大利亞等國的公路(lu)建設(she)中,均(jun)采用(yong)了鋼波(bo)紋管(guan)涵(han)(han)進(jin)行(xing)涵(han)(han)洞的施(shi)工。1990年,日本高速公路(lu)設(she)計(ji),規(gui)范制定了鋼波(bo)紋管(guan)涵(han)(han)設(she)計(ji)技(ji)術規(gui)范。
拼裝鋼(gang)波(bo)(bo)紋管(guan)是將(jiang)薄鋼(gang)板(ban)板(ban)面壓(ya)成波(bo)(bo)紋后(hou),卷制(zhi)成管(guan)節(jie),可以(yi)(yi)增加管(guan)節(jie)的(de)(de)(de)(de)剛度和對管(guan)軸壓(ya)力(li)的(de)(de)(de)(de)抵擋強度;出廠前采(cai)(cai)用(yong)熱浸鍍鋅工(gong)(gong)藝和施(shi)工(gong)(gong)現(xian)場噴涂瀝青(qing),雙層防腐處理(li)保(bao)證了(le)使用(yong)壽命;用(yong)此種(zhong)管(guan)節(jie)修建的(de)(de)(de)(de)涵(han)(han)(han)洞(dong)被稱為鋼(gang)波(bo)(bo)紋管(guan)涵(han)(han)(han)。實(shi)踐證實(shi),用(yong)鋼(gang)波(bo)(bo)紋管(guan)涵(han)(han)(han)代(dai)替鋼(gang)筋(jin)混(hun)凝(ning)土(tu)進行(xing)涵(han)(han)(han)洞(dong)施(shi)工(gong)(gong),不管(guan)從施(shi)工(gong)(gong)周期、施(shi)工(gong)(gong)造價(jia)、環(huan)保(bao)意(yi)義等方面都有其不可相比的(de)(de)(de)(de)優勝性(xing),且用(yong)鋼(gang)波(bo)(bo)紋管(guan)涵(han)(han)(han)進行(xing)涵(han)(han)(han)洞(dong)施(shi)工(gong)(gong),可大大進步道路行(xing)車的(de)(de)(de)(de)恬靜度與安全性(xing),避免(mian)道路中(zhong)涵(han)(han)(han)洞(dong)的(de)(de)(de)(de)“錯臺跳車”現(xian)形,有利(li)于解決西北(bei)地(di)區嚴(yan)寒霜(shuang)凍對砼管(guan)涵(han)(han)(han)結(jie)構的(de)(de)(de)(de)破(po)壞(huai)題目(mu)。公(gong)路工(gong)(gong)程的(de)(de)(de)(de)涵(han)(han)(han)洞(dong)一般采(cai)(cai)用(yong)鋼(gang)筋(jin)混(hun)凝(ning)土(tu)制(zhi)作。現(xian)采(cai)(cai)用(yong)鋼(gang)波(bo)(bo)紋管(guan)涵(han)(han)(han)代(dai)替鋼(gang)筋(jin)混(hun)凝(ning)土(tu)進行(xing)涵(han)(han)(han)洞(dong)施(shi)工(gong)(gong)在(zai)(zai)海內時一項(xiang)新技(ji)術,鋼(gang)波(bo)(bo)紋管(guan)涵(han)(han)(han)以(yi)(yi)其機能不亂、安裝利(li)便、有利(li)環(huan)保(bao)、造價(jia)低等長處迅速在(zai)(zai)公(gong)路施(shi)工(gong)(gong)中(zhong)代(dai)替了(le)鋼(gang)筋(jin)混(hun)凝(ning)土(tu)施(shi)工(gong)(gong)的(de)(de)(de)(de)涵(han)(han)(han)洞(dong),發展遠景(jing)非(fei)常廣(guang)闊。
