鋼波紋涵管是一種(zhong)柔性(xing)結構(gou)，鋼波紋涵管在(zai)結構(gou)上具有橫向(xiang)補償位移的特性(xing)，能夠充分(fen)發揮(hui)鋼材抗(kang)拉功能強、抗(kang)變(bian)形才(cai)干的特色，具有較大的抗(kang)變(bian)形才(cai)干和抗(kang)沉降才(cai)干，特別適(shi)合于軟(ruan)土、膨脹土、濕陷性(xing)黃(huang)土等(deng)地(di)(di)基承(cheng)載力較低的區域和地(di)(di)震多發區域。
因(yin)為(wei)鋼(gang)波紋涵管施(shi)工(gong)(gong)(gong)簡(jian)略且(qie)施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)期短(duan)（一般一道涵洞(dong)的施(shi)工(gong)(gong)(gong)時刻大約在10天-15天左右(you)）縮短(duan)了多年凍(dong)(dong)土的裸露時刻，凍(dong)(dong)融量小(xiao)，故特別適用(yong)于多年凍(dong)(dong)土區(qu)域。鋼(gang)波紋涵管施(shi)工(gong)(gong)(gong)時對(dui)周(zhou)圍(wei)環境(jing)的損壞小(xiao)，適用(yong)于生(sheng)態環境(jing)脆(cui)弱的區(qu)域鋼(gang)波紋涵管施(shi)工(gong)(gong)(gong)中只需要對(dui)基礎進行(xing)(xing)砂礫回填處理，對(dui)進出(chu)口進行(xing)(xing)混凝土或砌石施(shi)工(gong)(gong)(gong)處理，對(dui)砂、石材(cai)、鋼(gang)筋等(deng)用(yong)量小(xiao)，十分實用(yong)于砂石缺少的區(qu)域。
鋼(gang)波(bo)紋(wen)涵管選用標(biao)準化規劃(hua)、工廠加工出(chu)產(chan)，出(chu)產(chan)不(bu)受環境影響(xiang)，進行(xing)會合工廠化出(chu)產(chan)，出(chu)產(chan)周(zhou)期短，實(shi)用于質(zhi)量要求(qiu)高，工期緊，基礎差的(de)工程(cheng)項(xiang)目。鋼(gang)波(bo)紋(wen)涵管結構受力狀(zhuang)況合理，荷載散布均勻(yun)，并有一定的(de)抗(kang)變形才干(gan)。
削(xue)減(jian)或底(di)子拋棄了(le)慣例建材，如水泥、黃砂、石子、木材的(de)運用，環(huan)保意義(yi)深(shen)遠。處理北方冰冷區域（霜凍(dong)）對橋梁和管砼結構(gou)的(de)損壞問題。現場裝置(zhi)便利，不需運用大型(xing)設備。雨期施(shi)工(gong)應提早安排(pai)，盡量安排(pai)在降雨降臨前完結，基(ji)坑周邊(bian)有防水設施(shi)，避(bi)免(mian)邊(bian)水流入基(ji)坑內。
增加(jia)砂、石料含水量檢測頻率，及時調整混(hun)凝(ning)土(tu)合(he)作比，確保(bao)混(hun)凝(ning)土(tu)拌(ban)和(he)質量。應特別注(zhu)意(yi)做好供電(dian)(dian)(dian)(dian)線(xian)路保(bao)護，現場機電(dian)(dian)(dian)(dian)設備的電(dian)(dian)(dian)(dian)閘箱(xiang)應采取(qu)隱瞞(man)、防潮措施，電(dian)(dian)(dian)(dian)線(xian)做到絕緣良好，避免漏觸電(dian)(dian)(dian)(dian)事端發生。
從資(zi)料與構(gou)造和(he)功用的實質關系上分析，選用柔性高(gao)，強度的鋼波(bo)紋涵管(guan)洞，不(bu)只具有(you)習氣(qi)地(di)基(ji)與基(ji)礎(chu)(chu)變形的才干(gan)，能(neng)夠處(chu)理因地(di)基(ji)基(ji)礎(chu)(chu)不(bu)均勻沉降導致的涵洞損壞疑問，而且鋼波(bo)紋涵管(guan)洞因為軸向(xiang)波(bo)紋的存在使其具有(you)的受(shou)力特征，軸向(xiang)和(he)徑向(xiang)一同散布因荷載引起的應力應變，能(neng)夠更(geng)大程度上松(song)散荷載的應力會合，更(geng)好地(di)發揮鋼構(gou)造的優勢(shi)。
焊接時環境溫度應不低于-20℃，且應采取防雪、擋風等措施，削減焊件的溫度差。焊接后的接頭嚴禁當即接觸冰雪。冬期拌和混凝土時應嚴格操控混凝土的合作比和坍落度，集料不得帶有冰雪和凍結團塊。鋼波紋涵管投料前，應先選用熱水或蒸汽沖洗拌和機拌盤或鼓筒。//hanihanbj.com
