天安金屬波紋管的優點
1)金屬波紋管適應地基變形能(neng)力強,對地基承載能(neng)力、平整度要(yao)求較(jiao)低,工程實際造(zao)價(jia)比同類跨(kua)徑的橋、洞相近或較(jiao)低。
2) 施工工期短(duan)是最明(ming)顯(xian)的(de)優勢,土建工程與管節安裝可分開實施。
3)進行工廠(chang)集(ji)中化生(sheng)產,生(sheng)產不受環(huan)境影響,有利降低成本(ben)、控制質(zhi)量。
4) 金屬波紋管現場安裝方便,不需(xu)使用大型設(she)備。
5) 解決北方寒冷地區(霜凍)對橋梁和管砼結構的破壞問題(ti)。
6) 減少或根本舍棄了常規(gui)建(jian)材,如水泥、黃(huang)砂、石子、木(mu)材的使(shi)用,環(huan)保意義(yi)深(shen)遠。
7) 金屬波紋管結構受(shou)力(li)情況合(he)理,荷(he)載(zai)分布(bu)均勻(yun),并有一定的(de)抗變形能力(li)。
8) 金(jin)屬(shu)波紋管(guan)采用標(biao)準(zhun)化設(she)計,生產、設(she)計簡單,生產周期短。
9) 波(bo)紋管有利于改善軟土地基(ji)結構(gou)物與路堤交界處(chu)的“錯臺”現象,提高行車的舒適度與安全性,減少工后營運、養(yang)護成本。
鋼制波紋管(guan)是替代圓管(guan)、蓋(gai)板、和小橋(qiao)的優質公路建材。產品具(ju)有工期短、重量(liang)輕(qing)、安裝方便、耐久(jiu)性好、工廠造(zao)價低、抗變形(xing)能(neng)力強、減少(shao)通車后養護成(cheng)本等(deng)優點(dian),由其適合高寒凍土地區,軟土路基(ji)地帶和深(shen)填土地帶,可節(jie)省大(da)量(liang)資金,具(ju)有明顯的經濟效益。
