鋼制(zhi)波紋管(guan)涵(han)是采用鋼管(guan)熱浸鍍鋅(xin),所以使用壽(shou)命長,壽(shou)命為80-100年(nian),在腐蝕性(xing)特別大的環(huan)境下使用時,采用內外(wai)表(biao)面瀝清附(fu)層的鋼制(zhi)波紋管(guan),可在原使用壽(shou)命基礎_上(shang)提高約20年(nian)以上(shang)。
實踐證明,用鋼(gang)波紋(wen)涵(han)(han)管代替鋼(gang)筋混凝(ning)土進(jin)行涵(han)(han)洞施工,無論從(cong)施工周期、施工造價、環保意義等方面都有(you)其不(bu)可比擬的(de)優越性,且用鋼(gang)波紋(wen)管涵(han)(han)進(jin)行涵(han)(han)洞施工,可大(da)大(da)提高道路(lu)行車的(de)舒適(shi)度與安全性,避免道路(lu)中涵(han)(han)洞的(de)“錯臺跳(tiao)車”現形,有(you)利于解決西北(bei)地區寒冷霜凍(dong)對砼管涵(han)(han)結(jie)構的(de)破壞(huai)問題。
鋼波紋涵管結構物變形適(shi)應能力強不會出現砼結構開裂的通病,對基底處理要求較低,施工速(su)度快、抗震(zhen)性能好等優點也可以得(de)到(dao)充分發揮,
我(wo)公司生(sheng)產(chan)的(de)鋼波紋(wen)涵(han)管在出(chu)廠(chang)前嚴格(ge)按鋼波紋(wen)涵(han)管加工驗(yan)(yan)收標準進(jin)(jin)行,并工廠(chang)進(jin)(jin)行了預拼裝,保證(zheng)產(chan)品不合格(ge)不出(chu)廠(chang)。鋼波紋(wen)涵(han)管出(chu)廠(chang)時,進(jin)(jin)行出(chu)廠(chang)檢(jian)驗(yan)(yan)。檢(jian)驗(yan)(yan)項目按照《公路涵(han)洞通道用波紋(wen)鋼管(板)》(JT /T規范中第條的(de)規定的(de)內容進(jin)(jin)行檢(jian)驗(yan)(yan)。檢(jian)驗(yan)(yan)合格(ge)后并附有產(chan)品質量合格(ge)證(zheng)書(shu)和質檢(jian)報(bao)告。
鋼波紋涵管現場安裝時,必須嚴格按照設計以及鋼波紋涵管施工安裝規范的要求施工。現場施工中土建部分驗收標準可參照交通部《公路工程質量檢驗評定標準》JTGF中有關標準,鋼波紋涵管外回填土的驗收可歸入路基工程之中。波紋鋼板運到施工現場后,必須逐塊檢查。材料出廠時己進行了熱鍍鋅防腐處理,運輸工地后,卸貨時不可直接翻拉,應采用吊車配合人工進行裝卸,避免損壞鍍鋅層。卸車后進行外觀檢查,防止出現損傷變形、裝卸劃痕、鍍鋅層損壞、切口有不規則鋸齒現象。涵洞基礎的地基承載力必須滿足設計要求,嚴禁超挖、自填虛土以及標高控制。、鋼波紋涵管在安裝時,拼接處必須清理干凈,保證拼縫搭接緊密,防止有空隙。、鋼波紋涵管在二次防腐處理前,應按施工順序在搭接處用密封膠涂裝,防止滲水。//hanihanbj.com/
