鋼波紋涵管是(shi)一種柔性(xing)結構(gou)(gou),鋼(gang)波紋涵管在結構(gou)(gou)上具有橫(heng)向補(bu)償位移(yi)的特性(xing),能(neng)夠充分發揮鋼(gang)材抗拉(la)功能(neng)強、抗變形才(cai)干的特色(se),具有較大的抗變形才(cai)干和抗沉降才(cai)干,特別適合于軟土、膨脹土、濕陷(xian)性(xing)黃(huang)土等(deng)地基承載力較低的區域(yu)和地震多發區域(yu)。
因為(wei)鋼波(bo)紋涵管施(shi)(shi)工(gong)(gong)(gong)簡略且施(shi)(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)期短(duan)(一般一道(dao)涵洞的施(shi)(shi)工(gong)(gong)(gong)時刻(ke)大約在10天(tian)(tian)-15天(tian)(tian)左右)縮短(duan)了多(duo)年(nian)凍土(tu)的裸露時刻(ke),凍融量(liang)小,故特別適用(yong)于(yu)多(duo)年(nian)凍土(tu)區域(yu)。鋼波(bo)紋涵管施(shi)(shi)工(gong)(gong)(gong)時對周圍環境的損壞小,適用(yong)于(yu)生(sheng)態(tai)環境脆(cui)弱(ruo)的區域(yu)鋼波(bo)紋涵管施(shi)(shi)工(gong)(gong)(gong)中只需要對基礎進行砂礫回填處理,對進出口進行混(hun)凝土(tu)或砌石(shi)(shi)施(shi)(shi)工(gong)(gong)(gong)處理,對砂、石(shi)(shi)材、鋼筋等用(yong)量(liang)小,十(shi)分實用(yong)于(yu)砂石(shi)(shi)缺(que)少的區域(yu)。
鋼波紋涵(han)管選用標(biao)準化規劃、工廠(chang)加工出(chu)產(chan),出(chu)產(chan)不(bu)受(shou)環(huan)境(jing)影響,進行會合(he)(he)工廠(chang)化出(chu)產(chan),出(chu)產(chan)周期短,實用于質量要(yao)求(qiu)高,工期緊,基礎差的工程項目。鋼波紋涵(han)管結構(gou)受(shou)力狀況(kuang)合(he)(he)理,荷(he)載散布(bu)均(jun)勻,并(bing)有一定(ding)的抗變形才干(gan)。
削減或(huo)底子(zi)拋棄了慣例建材(cai),如水泥(ni)、黃砂、石子(zi)、木材(cai)的運(yun)用,環保意義深遠。處理(li)北(bei)方(fang)冰冷區域(霜凍)對橋梁(liang)和(he)管砼結(jie)(jie)構的損壞(huai)問題。現場裝置(zhi)便利(li),不需運(yun)用大型(xing)設備。雨(yu)期施工應提(ti)早(zao)安排,盡量安排在降雨(yu)降臨前(qian)完結(jie)(jie),基坑周邊有防水設施,避免邊水流入基坑內。
