鋼制波紋涵管易維護,只需(xu)做好(hao)內壁的防(fang)護保養即可。鋼(gang)波(bo)(bo)紋涵管(guan)在(zai)高喊(han)凍土(tu)地(di)區(qu),軟(ruan)土(tu)路基地(di)帶,具有(you)明顯的經(jing)濟效益(yi)。其(qi)良好(hao)的整體性(xing)、可塑性(xing)對地(di)質條件(jian)復雜路段抗(kang)變形能力強。鋼(gang)波(bo)(bo)紋涵管(guan)經(jing)過(guo)了防(fang)腐(fu)處理耐久性(xing)高。其(qi)良好(hao)的導熱性(xing)對凍土(tu)區(qu)的路基擾動小(xiao),路基穩定。鋼(gang)波(bo)(bo)紋涵管(guan)出(chu)廠(chang)時(shi),應進行出(chu)廠(chang)檢驗。
鋼制波紋涵管運到現場后這樣安裝非常實用
產品需檢驗(yan)合(he)格并附(fu)有產品質量(liang)合(he)格證(zheng)書(shu)方(fang)可出廠。波紋鋼(gang)板(ban)運到施工現場后,必須逐塊檢查。

材料(liao)出廠時己(ji)進行鍍(du)鋅防腐處(chu)理,運輸工地后,卸貨時不(bu)可直接翻拉,應采用吊車配(pei)合人工進行裝卸,避免損壞(huai)鍍(du)鋅層。鋼波(bo)紋涵管進行外(wai)觀檢查,防止出現損傷變形、裝卸劃(hua)痕、鍍(du)鋅層損壞(huai)、切口有不(bu)規則鋸齒現象。
鋼波(bo)紋涵管(guan)采用工(gong)(gong)廠化生產,生產不受環(huan)境影(ying)響并有利(li)于控制(zhi)質量。鋼波(bo)紋涵管(guan)現(xian)場(chang)拼裝(zhuang),必須(xu)嚴格按照(zhao)設計以及鋼波(bo)紋涵管(guan)施(shi)工(gong)(gong)安裝(zhuang)規(gui)范的要求施(shi)工(gong)(gong)。現(xian)場(chang)施(shi)工(gong)(gong)中(zhong)土(tu)建部(bu)分驗(yan)(yan)(yan)收標準(zhun)可(ke)參照(zhao)交通(tong)部(bu)《公(gong)路工(gong)(gong)程質量檢驗(yan)(yan)(yan)評(ping)定標準(zhun)》JTGF80/1-2004中(zhong)有關標準(zhun),鋼波(bo)紋涵管(guan)外(wai)回填土(tu)的驗(yan)(yan)(yan)收可(ke)歸入路基工(gong)(gong)程之中(zhong)。拼裝(zhuang)施(shi)工(gong)(gong),工(gong)(gong)期短、重量輕、安裝(zhuang)方便,在高海拔地區減少大量人工(gong)(gong),并可(ke)在冬季施(shi)工(gong)(gong)。(hanihanbj.com)
