鋼波紋涵管是一種柔性結(jie)構，鋼(gang)(gang)波紋涵(han)管在結(jie)構上具有橫向補償位移的特(te)性，能夠充分發(fa)揮(hui)鋼(gang)(gang)材抗拉功能強、抗變(bian)形(xing)才(cai)干(gan)的特(te)色，具有較(jiao)大的抗變(bian)形(xing)才(cai)干(gan)和抗沉(chen)降才(cai)干(gan)，特(te)別適合于軟土、膨脹(zhang)土、濕(shi)陷性黃土等地基承載力較(jiao)低的區(qu)域(yu)和地震多發(fa)區(qu)域(yu)。

因(yin)為鋼(gang)波紋(wen)涵(han)(han)管(guan)施(shi)工(gong)(gong)(gong)簡(jian)略(lve)且(qie)施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)期(qi)短(duan)（一(yi)般一(yi)道涵(han)(han)洞的施(shi)工(gong)(gong)(gong)時(shi)刻(ke)大約在10天-15天左右(you)）縮短(duan)了(le)多年凍(dong)(dong)土的裸露時(shi)刻(ke)，凍(dong)(dong)融量(liang)小(xiao)，故(gu)特別適用(yong)(yong)于多年凍(dong)(dong)土區(qu)(qu)域(yu)(yu)。鋼(gang)波紋(wen)涵(han)(han)管(guan)施(shi)工(gong)(gong)(gong)時(shi)對(dui)(dui)周圍環(huan)境(jing)的損壞小(xiao)，適用(yong)(yong)于生態環(huan)境(jing)脆弱(ruo)的區(qu)(qu)域(yu)(yu)鋼(gang)波紋(wen)涵(han)(han)管(guan)施(shi)工(gong)(gong)(gong)中只需要對(dui)(dui)基礎進行(xing)砂(sha)礫(li)回(hui)填(tian)處理，對(dui)(dui)進出口進行(xing)混凝土或砌石施(shi)工(gong)(gong)(gong)處理，對(dui)(dui)砂(sha)、石材、鋼(gang)筋等(deng)用(yong)(yong)量(liang)小(xiao)，十分實用(yong)(yong)于砂(sha)石缺(que)少的區(qu)(qu)域(yu)(yu)。

鋼波紋涵管

鋼波紋(wen)涵管選用標準(zhun)化規劃、工(gong)(gong)廠加工(gong)(gong)出產(chan)，出產(chan)不受環境影響，進(jin)行會合(he)工(gong)(gong)廠化出產(chan)，出產(chan)周期(qi)短，實用于質(zhi)量要求高(gao)，工(gong)(gong)期(qi)緊(jin)，基礎差的工(gong)(gong)程(cheng)項目。鋼波紋(wen)涵管結構受力(li)狀況合(he)理(li)，荷載散布均(jun)勻(yun)，并有一(yi)定的抗變形(xing)才干。

削減或(huo)底子拋棄了慣例建(jian)材，如水(shui)泥(ni)、黃砂、石子、木材的運(yun)用(yong)，環保意義深(shen)遠(yuan)。處理北方冰冷區(qu)域(yu)（霜凍(dong)）對橋梁和管砼結(jie)構的損壞問題。現(xian)場裝置便利，不需運(yun)用(yong)大(da)型設備。雨期施工(gong)應提早安排(pai)，盡量安排(pai)在降雨降臨(lin)前完結(jie)，基坑周(zhou)邊有防(fang)水(shui)設施，避免邊水(shui)流入(ru)基坑內。
