鋼波紋管可增強涵(han)洞(dong)的防(fang)水(shui)功(gong)能,對(dui)腐蝕及沖刷(shua)較為(wei)嚴重的場合(he),除在(zai)外壁增加2道熱(re)涂瀝青層外,可考慮在(zai)管(guan)內(nei)壁包裹一層C25細石砼,更(geng)能加強涵(han)洞(dong)受水(shui)流沖刷(shua)的才能,保證對(dui)鋼波紋涵(han)管(guan)壁的維護。
鋼波紋管,壓箱底的好物!
鋼(gang)(gang)波(bo)紋管具有(you)重(zhong)量(liang)輕,工程施工簡易(yi)、工期短等優勢(shi),鋼(gang)(gang)波(bo)紋管底端(duan)及兩頭可添(tian)充(chong)砂(sha)礫、碎石(shi)土、片石(shi)砼(tong)等原(yuan)材(cai)料,鋼(gang)(gang)波(bo)紋涵管頂端(duan)能用高(gao)壓水(shui)泵送(song)脹大水(shui)泥(ni)砂(sha)漿或(huo)砌墻片石(shi)澎漲(zhang)砼(tong),此方(fang)法(fa)在舊橋工程加固(gu)中獲得了非常好的實(shi)踐作用。
因為管(guan)土(tu)功效(xiao),鋼(gang)波(bo)(bo)紋涵管(guan)提升了融入地(di)(di)基與(yu)根底形變的工(gong)作才能,合理(li)的處(chu)理(li)路(lu)基不(bu)勻(yun)稱地(di)(di)基沉降造成導流洞破壞難題。并且鋼(gang)波(bo)(bo)紋涵管(guan)因為波(bo)(bo)浪紋的存有使其具有支(zhi)承特點,因為軸方向和徑向一(yi)起(qi)承當負(fu)荷(he)而產(chan)生的應力應變,能夠更大(da)程度地(di)(di)渙散負(fu)荷(he)的作用(yong)。
鋼波紋(wen)管(guan)選用標準化(hua)規劃,出(chu)產(chan),規劃簡略,出(chu)產(chan)周期短;工(gong)(gong)程實踐造價比同類跨徑的橋(qiao),涵(han)洞(dong)(dong)低(di);施(shi)工(gong)(gong)工(gong)(gong)期短,主要為(wei)拼裝施(shi)工(gong)(gong);鋼波紋(wen)涵(han)管(guan)替代鋼筋混凝土進行涵(han)洞(dong)(dong)施(shi)工(gong)(gong),無論從施(shi)工(gong)(gong)周期,施(shi)工(gong)(gong)造價,環保(bao)意義等方面都有(you)其不行比擬的。
鍍鋅構件外表應具有均勻完整的涂層,色彩共同,外表具有實用性光滑,不允許有流掛、滴瘤或多余結塊。鍍件外表應無漏鍍、露鐵等缺點。有螺紋的構件在熱浸鍍鋅后,應整理螺紋或作離心分離。鍍鋅構件的鋅層應均勻,試樣經硫酸銅溶液浸蝕5次不變紅。鍍鋅構件的鮮層應與基底鋼結合牢固,經錘擊試驗鍍鋅層不剝離、不凸起。//hanihanbj.com/
