鋼波紋涵管是一種柔(rou)性結(jie)構,鋼波紋涵管在結(jie)構上(shang)具(ju)有(you)橫向補(bu)償位移的(de)特性,能(neng)夠充分發揮鋼材抗(kang)(kang)拉功能(neng)強、抗(kang)(kang)變形才(cai)干的(de)特色,具(ju)有(you)較(jiao)大的(de)抗(kang)(kang)變形才(cai)干和(he)抗(kang)(kang)沉降(jiang)才(cai)干,特別(bie)適(shi)合于軟(ruan)土(tu)、膨脹土(tu)、濕陷性黃土(tu)等地基承(cheng)載(zai)力較(jiao)低的(de)區域和(he)地震多(duo)發區域。
因(yin)為鋼(gang)(gang)波紋(wen)(wen)涵管(guan)施(shi)工(gong)簡略且(qie)施(shi)工(gong)工(gong)期短(一(yi)般一(yi)道涵洞的施(shi)工(gong)時刻大約在10天-15天左右)縮短了多年(nian)凍土的裸露時刻,凍融量小,故特別適用(yong)(yong)于(yu)(yu)多年(nian)凍土區(qu)(qu)域(yu)。鋼(gang)(gang)波紋(wen)(wen)涵管(guan)施(shi)工(gong)時對周圍環(huan)境(jing)(jing)的損壞小,適用(yong)(yong)于(yu)(yu)生態環(huan)境(jing)(jing)脆弱的區(qu)(qu)域(yu)鋼(gang)(gang)波紋(wen)(wen)涵管(guan)施(shi)工(gong)中只(zhi)需要對基礎進(jin)行砂(sha)礫回(hui)填處理,對進(jin)出口進(jin)行混凝土或砌石施(shi)工(gong)處理,對砂(sha)、石材、鋼(gang)(gang)筋等用(yong)(yong)量小,十分(fen)實用(yong)(yong)于(yu)(yu)砂(sha)石缺少的區(qu)(qu)域(yu)。
鋼波紋涵管(guan)選用標(biao)準(zhun)化(hua)規(gui)劃、工(gong)(gong)廠加工(gong)(gong)出產,出產不受環境(jing)影響,進行會合工(gong)(gong)廠化(hua)出產,出產周期(qi)短,實用于質(zhi)量要求高,工(gong)(gong)期(qi)緊,基礎(chu)差的工(gong)(gong)程(cheng)項目。鋼波紋涵管(guan)結(jie)構受力狀況合理,荷(he)載散布均(jun)勻,并有一定的抗變形才干。
削減或(huo)底(di)子拋棄了慣例建材,如水(shui)泥(ni)、黃(huang)砂、石子、木材的運用,環保(bao)意義深遠。處理北方(fang)冰冷區域(霜凍)對(dui)橋(qiao)梁和管砼結構(gou)的損壞問題。現(xian)場裝置便利,不需(xu)運用大型(xing)設(she)備。雨期施工應提早安(an)排,盡量安(an)排在降(jiang)雨降(jiang)臨前完(wan)結,基坑周邊有防水(shui)設(she)施,避免邊水(shui)流入基坑內。
