和(he)管連接完成后的現(xian)場涂瀝(li)青能完全避免常年水泡和(he)酸堿土壤的侵蝕(shi),保(bao)證使用壽命及人員設備的安(an)全。波紋(wen)涵管(guan)有利于改善軟土(tu)地(di)基結構物與路堤交界處的“錯臺”現象,提高行車的舒適度與安全性,減少工后營(ying)運、養護(hu)成本。
標準化設計的(de)鋼波紋涵(han)管(guan)的(de)生產周期(qi)要多久(jiu)?
涵(han)(han)(han)管(guan)(guan)(guan)、波紋(wen)(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)、鋼(gang)制波紋(wen)(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)洞(dong)、金屬波紋(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)(guan)結(jie)(jie)構受力情況合理,荷載分布均勻,并有一(yi)定的抗變形(xing)能力。解決北(bei)方寒冷地區(霜(shuang)凍)對(dui)橋梁(liang)和(he)管(guan)(guan)(guan)涵(han)(han)(han)砼結(jie)(jie)構的破壞問(wen)題。涵(han)(han)(han)管(guan)(guan)(guan)、波紋(wen)(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)、鋼(gang)制波紋(wen)(wen)(wen)管(guan)(guan)(guan)涵(han)(han)(han)洞(dong)、金屬波紋(wen)(wen)(wen)涵(han)(han)(han)管(guan)(guan)(guan)采用標準(zhun)化設計,生產(chan)、設計簡單,生產(chan)周期短(duan)。
鐵路鋼(gang)波紋管
鋼(gang)波紋(wen)涵(han)管是替代圓管涵(han)、蓋板(ban)涵(han)、和小橋的優質(zhi)公路建材。鋼(gang)波紋(wen)涵(han)管具(ju)有工期短(duan)、重量輕、安(an)裝(zhuang)方(fang)便、耐久性好、工廠造價低、抗變形能力強(qiang)、減少通(tong)車后養護(hu)成(cheng)本等優點,由其適合高寒凍土(tu)地區(qu),軟(ruan)土(tu)路基地帶(dai)和深填土(tu)地帶(dai),可節省大量資金,具(ju)有明顯(xian)的經濟(ji)效益(yi)。
施(shi)(shi)工(gong)(gong)工(gong)(gong)期短是(shi)明顯的優勢,土建工(gong)(gong)程與管節安裝可分開(kai)實施(shi)(shi)。進行(xing)工(gong)(gong)廠集中(zhong)(zhong)化生產,生產不受環境影響,有利降低成(cheng)本、控(kong)制質(zhi)量。簡(jian)捷便(bian)道(dao)施(shi)(shi)工(gong)(gong)在(zai)一些河流及橋梁施(shi)(shi)工(gong)(gong)中(zhong)(zhong),建材需跨河運輸,將來(lai)橋基建成(cheng)后還(huan)需要運送承載梁,所以必須修建臨時便(bian)道(dao),以方便(bian)運輸。
減少或根本舍棄了(le)常(chang)規建(jian)材,如水泥、黃砂、石(shi)子、木材的(de)使用(yong),環保(bao)意義深遠。高寒地帶(dai)施工(gong)(gong)可(ke)冬季施工(gong)(gong),不受氣候影響,進行冬季以(yi)后,我國北方的(de)廣大地區(qu)氣候寒冷,修建(jian)蓋板涵(han)(han)或石(shi)拱涵(han)(han)由于氣溫過低,會造成不同程度的(de)破(po)壞(huai),在施工(gong)(gong)工(gong)(gong)程工(gong)(gong)期短(duan),條(tiao)件惡劣的(de)情況下,使用(yong)鋼波(bo)紋涵(han)(han)管可(ke)以(yi)很容易的(de)克服施工(gong)(gong)中的(de)各種困難。
煤(mei)礦采(cai)空區施工:我國(guo)是(shi)一(yi)個煤(mei)炭大(da)國(guo),受開采(cai)條件的限制,地下采(cai)空可造(zao)成地面不同(tong)(tong)程度的下降,產生不均勻沉(chen)降,對一(yi)般(ban)水泥構造(zao)物易產生裂紋(wen)`、錯位等不同(tong)(tong)程度的破壞,金(jin)屬波(bo)紋(wen)涵管是(shi)一(yi)種柔性結構,鋼波紋管在結構(gou)上具(ju)有橫向補償位(wei)移的優(you)良特性(xing)(xing),可充分發(fa)(fa)揮鋼材抗(kang)拉性(xing)(xing)能(neng)(neng)強,變形(xing)性(xing)(xing)能(neng)(neng)優(you)越的特點,具(ju)有較大(da)的抗(kang)變形(xing)和抗(kang)沉(chen)降能(neng)(neng)力,特別適合軟(ruan)土(tu)、膨(peng)脹土(tu)地、濕陷性(xing)(xing)黃土(tu)等地基承載力較低地區(qu)和地震多(duo)發(fa)(fa)地區(qu)。
整裝鋼波紋涵管(guan)
但有時河內(nei)常(chang)年水(shui)流不止,施工條件困難,使用鋼波紋涵管時,在河內(nei)倒入(ru)片石,加30cm砂礫(li)墊層軋實,管側及(ji)頂部(bu)(bu)全(quan)部(bu)(bu)澆筑砼,與混凝土小橋相比(bi),既縮短了工期,又降低了成本(ben)。相比(bi)較浮(fu)橋在安全(quan)性及(ji)承載方面也有很(hen)大的提(ti)高(gao)。
涵(han)(han)(han)管(guan)(guan)、波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)(han)、鋼制波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)(han)洞、金屬波(bo)(bo)(bo)紋(wen)涵(han)(han)(han)管(guan)(guan)現場安(an)裝方便,不(bu)需使用大型(xing)設備。鋼波(bo)(bo)(bo)紋(wen)涵(han)(han)(han)管(guan)(guan)使用優點(dian):涵(han)(han)(han)管(guan)(guan)、波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)(han)、鋼制波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)(han)(han)洞、金屬波(bo)(bo)(bo)紋(wen)涵(han)(han)(han)管(guan)(guan)適應地(di)基變(bian)形能力(li)強,對地(di)基承載能力(li)、平整度(du)要(yao)求較低(di),工(gong)程實際造價比同類跨徑的(de)橋、涵(han)(han)(han)洞相(xiang)近或較低(di)。想了解更(geng)多關(guan)于鋼波(bo)(bo)(bo)紋(wen)涵(han)(han)(han)管(guan)(guan)的(de)新聞動(dong)態請點(dian)擊:hanihanbj.com
