鋼波紋涵管是一(yi)種柔性(xing)結(jie)構(gou),鋼(gang)(gang)波紋涵管在結(jie)構(gou)上具有橫向(xiang)補償位(wei)移的特性(xing),能夠充(chong)分發揮鋼(gang)(gang)材抗(kang)拉功能強、抗(kang)變形才(cai)干的特色(se),具有較大的抗(kang)變形才(cai)干和抗(kang)沉降才(cai)干,特別適合于軟(ruan)土(tu)(tu)、膨脹土(tu)(tu)、濕陷(xian)性(xing)黃土(tu)(tu)等地基(ji)承載力較低(di)的區域和地震多發區域。
因為鋼(gang)波(bo)紋涵(han)管(guan)(guan)施(shi)工(gong)(gong)(gong)簡略且施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)期短(一般一道涵(han)洞的(de)施(shi)工(gong)(gong)(gong)時刻大約在10天-15天左右)縮短了多(duo)(duo)年(nian)凍(dong)土(tu)的(de)裸露時刻,凍(dong)融量(liang)(liang)小(xiao),故特別適用(yong)于(yu)多(duo)(duo)年(nian)凍(dong)土(tu)區域(yu)。鋼(gang)波(bo)紋涵(han)管(guan)(guan)施(shi)工(gong)(gong)(gong)時對(dui)(dui)周圍環(huan)境的(de)損壞(huai)小(xiao),適用(yong)于(yu)生態環(huan)境脆弱的(de)區域(yu)鋼(gang)波(bo)紋涵(han)管(guan)(guan)施(shi)工(gong)(gong)(gong)中只需要對(dui)(dui)基礎進行砂礫回填處理,對(dui)(dui)進出口進行混凝土(tu)或砌(qi)石施(shi)工(gong)(gong)(gong)處理,對(dui)(dui)砂、石材、鋼(gang)筋等用(yong)量(liang)(liang)小(xiao),十分實用(yong)于(yu)砂石缺少的(de)區域(yu)。
鋼(gang)波紋涵管選用(yong)標準化規劃、工廠(chang)加(jia)工出產(chan)(chan),出產(chan)(chan)不受環境影響,進行會合(he)(he)工廠(chang)化出產(chan)(chan),出產(chan)(chan)周期短,實用(yong)于質量(liang)要(yao)求(qiu)高,工期緊,基礎差的工程項目。鋼(gang)波紋涵管結(jie)構受力狀(zhuang)況(kuang)合(he)(he)理,荷載散布(bu)均勻,并(bing)有一定(ding)的抗變形才干。
削(xue)減或底子拋棄了慣例建(jian)材,如水(shui)泥(ni)、黃砂、石(shi)子、木材的運用,環保意義深遠。處理(li)北方(fang)冰冷區域(yu)(霜(shuang)凍)對橋梁和管砼結構的損壞(huai)問題。現場(chang)裝置便利,不需運用大(da)型設備。雨期施工(gong)應提早安排(pai),盡量安排(pai)在降(jiang)雨降(jiang)臨前完結,基坑周邊有(you)防(fang)水(shui)設施,避(bi)免(mian)邊水(shui)流(liu)入基坑內。
