橋梁(liang)鋼波紋涵(han)管對周圍生態環境(jing)如何進(jin)行保護？

鋼波紋管涵洞技(ji)術(shu)不僅(jin)具(ju)有施工周期(qi)短、適應(ying)能力強、地基承載力要求低(di)的特點，而(er)且具(ju)有較強的耐性，可以(yi)大大減少施工的時間，因而(er)這種技(ji)術(shu)被運用(yong)。必(bi)須(xu)采用(yong)有效措施，確保鋼波紋管回(hui)填土質量(liang)。鋼波紋涵管在(zai)安裝(zhuang)時，拼接(jie)處必(bi)須(xu)清理干(gan)凈。以(yi)確保拼縫搭接(jie)緊密。

鋼波紋管涵具有施工工期(qi)短(duan)、重量(liang)輕、安(an)裝方便、耐久性(xing)能好、工程造價(jia)低、抗變形能力強(qiang)、減少(shao)養護(hu)費用成(cheng)本等優點。鋼波紋涵管使用范圍(wei)：基(ji)本要求：高強(qiang)螺栓緊固后，在二次(ci)防腐處(chu)理前，應在搭(da)接處(chu)用密封防水材料(liao)(或熱(re)瀝青(qing))涂(tu)裝。

拼接(jie)波紋(wen)管涵

具有較大的(de)抗(kang)變形能力和抗(kang)沉降能力，特(te)別適合(he)于(yu)軟土(tu)、膨脹土(tu)、濕(shi)陷性黃(huang)土(tu)等地(di)(di)基承載力較低的(de)地(di)(di)區和地(di)(di)震多發地(di)(di)區。鋼(gang)質波紋板通道(dao)現場拼裝，必(bi)須(xu)嚴格。按設計以及鋼(gang)質波紋板通道(dao)施工(gong)安裝規范的(de)要求施工(gong)。鋼(gang)波紋涵(han)管作為一種(zhong)新(xin)型技術在公路涵(han)洞(dong)工(gong)程施工(gong)中的(de)具有很大的(de)優勢。

基礎的地基承(cheng)載力必(bi)須滿足沒(mei)計要求，嚴禁超(chao)挖回填虛土(tu)(tu)超(chao)過(guo)以(yi)及標高(gao)控制。波紋(wen)(wen)鋼(gang)板安裝(zhuang)鋪(pu)設應平(ping)順、穩固、管(guan)(guan)(guan)底坡度不得出現反坡，管(guan)(guan)(guan)涵(han)內不得有(you)泥土(tu)(tu)、磚石等雜(za)物。鋼(gang)波紋(wen)(wen)涵(han)管(guan)(guan)(guan)是一種(zhong)柔(rou)性(xing)(xing)結(jie)構，波紋(wen)(wen)管(guan)(guan)(guan)涵(han)在結(jie)構上具(ju)有(you)橫向補償(chang)位移的優良特性(xing)(xing)，可以(yi)充分發揮鋼(gang)材抗拉性(xing)(xing)能(neng)(neng)強、抗變(bian)形能(neng)(neng)力優越的特點。

鋼(gang)(gang)波紋(wen)(wen)(wen)涵(han)管(guan)的優點：鋼(gang)(gang)波紋(wen)(wen)(wen)涵(han)管(guan)單體出廠(chang)時(shi)，必須(xu)附(fu)有(you)(you)產品質(zhi)量合格證(zheng)書，沒有(you)(you)合格證(zheng)書的一律不能出廠(chang)。鋼(gang)(gang)波紋(wen)(wen)(wen)涵(han)管(guan)從材料(liao)與(yu)結構和功(gong)能的本質(zhi)關(guan)系上分析，采用柔性(xing)高強度(du)的鋼(gang)(gang)波紋(wen)(wen)(wen)管(guan)涵(han)洞(dong)由于(yu)軸(zhou)向波紋(wen)(wen)(wen)的存(cun)在，使其具有(you)(you)優良的受(shou)力(li)(li)特(te)征，軸(zhou)向和徑(jing)向同時(shi)分布因荷載引起(qi)的應力(li)(li)應變，可以更大程度(du)上分散荷載的應力(li)(li)集中(zhong)，更好地發揮鋼(gang)(gang)結構的優勢(shi)。

由于鋼(gang)(gang)波紋涵管施(shi)工(gong)簡(jian)單且施(shi)工(gong)工(gong)期(qi)短（一(yi)般一(yi)道涵洞(dong)的(de)施(shi)工(gong)時(shi)間(jian)大約在(zai)10天(tian)-15天(tian)左右(you)）縮短了多年凍土(tu)的(de)裸露(lu)時(shi)間(jian)，凍融(rong)量(liang)小，故特別適用(yong)于多年凍土(tu)地區。鋼(gang)(gang)波紋涵管運(yun)到施(shi)工(gong)現(xian)場(chang)后，必須逐塊檢查(cha)，凡在(zai)運(yun)輸過程中變形的(de)鋼(gang)(gang)板不得(de)使用(yong)。（hanihanbj.com）
