鋼波紋管涵(han)結構強度高，勢(shi)鋼筋混凝土的1-3倍，對(dui)地基承載才能(neng)，平(ping)整度要(yao)求較低(di)，工(gong)程實際造價比(bi)同類(lei)跨徑的橋，涵(han)洞相近(jin)或較低(di)。運營(ying)壽命長，可達100多年。鋼波紋管(guan)施工(gong)人員(yuan)要(yao)熟知本工(gong)種的安全操作規程，堅守崗位。

進行縱向銜接成(cheng)型(xing)，銜接螺(luo)栓釆用M20,8.8級高強度螺(luo)栓及(ji)弧形墊(dian)圈，邊(bian)縫及(ji)螺(luo)栓用密封膠處(chu)理(li)，鋼(gang)板外表選用熱浸(jin)鍍鋅。拼裝完成(cheng)后用噴(pen)涂瀝青。洞口(kou)鋪(pu)砌及(ji)護坡(po)選用M7.5漿砌片石鋪(pu)砌貨(huo)釆用鋼(gang)筋(jin)混凝土澆(jiao)筑洞口(kou)。

鋼波紋管

鋼波(bo)紋管(guan)涵是一種柔性(xing)結構(gou)，它(ta)建(jian)成(cheng)(cheng)后與周(zhou)圍土體(ti)構(gou)成(cheng)(cheng)一種組(zu)合(he)結構(gou)，共(gong)同受(shou)力，波(bo)紋管(guan)涵楔(xie)形(xing)部(bu)及兩(liang)邊的(de)回(hui)填土很關鍵，如果(guo)回(hui)填不密實或有楔(xie)形(xing)部(bu)中空或部(bu)分(fen)(fen)(fen)有大石(shi)塊直接(jie)作用于管(guan)體(ti)，將出現部(bu)分(fen)(fen)(fen)有較大變形(xing)或部(bu)分(fen)(fen)(fen)有凸起，存在安全(quan)隱患(huan)，嚴峻的(de)可能會造成(cheng)(cheng)質量事故。

所以鋼波紋管兩邊及楔形部的回填土在施工中要嚴格操控。施工周期短，工廠集中化出產，出產不受環境影響，有利降低成本，操控質量。重量輕，施工便捷，現場安裝方便，不需使用大型設備。解決北方冰冷區域（霜凍）對橋梁和管涵砼結構的破壞問題。//hanihanbj.com/
