鋼波紋涵管出(chu)廠(chang)時,要附有產品質量(liang)合格證書(shu),沒(mei)有合格證書(shu)的一概不能出(chu)廠(chang)。鋼波紋涵管運(yun)到施工現(xian)場后,要逐塊(kuai)檢查,凡在運(yun)輸過(guo)程中變形的鋼板不得用。基(ji)礎的地基(ji)承載力要滿(man)意沒(mei)計要求,嚴禁超(chao)挖(wa)回填虛土超(chao)過(guo)以及(ji)標高(gao)控制。

鋼(gang)(gang)波(bo)(bo)紋涵管在裝(zhuang)置時(shi),拼接處要清理潔凈(jing)。以保證拼縫搭(da)接緊(jin)密。在實踐條件答(da)應的(de)情況下,應先考慮采用改動鋼(gang)(gang)波(bo)(bo)紋涵管管道的(de)走向和繃簧支吊架的(de)方(fang)法來(lai)添加管道的(de)柔(rou)性。一(yi)般情況下,當兩個(ge)固定點位置是一(yi)定時(shi),添加鋼(gang)(gang)波(bo)(bo)紋涵管系長度和彎頭數量能夠(gou)添加管道的(de)柔(rou)性。
當鋼波紋涵(han)管在(zai)某一方向(xiang)的(de)剛度(du)過大時,添(tian)加(jia)與(yu)其(qi)垂(chui)直(zhi)方向(xiang)的(de)管道(dao)長度(du)可減小管涵(han)的(de)剛度(du)。選用繃簧支吊(diao)架能夠(gou)使支吊(diao)架處存在(zai)垂(chui)直(zhi)位移,將約束放松(song),添(tian)加(jia)其(qi)柔性。當鋼波紋涵(han)管管徑較大、場(chang)地受限制而且所需求的(de)補償量較大時,能夠(gou)考慮(lv)用波紋管膨脹(zhang)節來添(tian)加(jia)管道(dao)柔性。
When the stiffness of steel corrugated culvert pipe in a certain direction is too large, adding the pipe length perpendicular to it can reduce the stiffness of pipe culvert. The use of tension spring supports and hangers can make the supports and hangers have vertical displacement, relax the constraints and add their flexibility. When the diameter of steel corrugated culvert pipe is large, the site is limited and the compensation required is large, corrugated pipe expansion joint can be considered to add pipe flexibility.

但是(shi)波紋管(guan)(guan)膨脹節制作雜亂,價格(ge)偏(pian)高,它適用(yong)于低壓大直(zhi)徑(jing)管(guan)(guan)道,但波紋管(guan)(guan)膨脹節是(shi)管(guan)(guan)道中的薄(bo)弱環(huan)節,應盡(jin)量防(fang)止采(cai)用(yong)。能夠在金屬波紋管(guan)(guan)涵(han)表里(li)管(guan)(guan)壁(bi)涂上或(huo)(huo)者(zhe)噴上含有石棉纖維的厚瀝(li)(li)青(qing)。或(huo)(huo)者(zhe)是(shi)涂刷(shua)兩(liang)邊瀝(li)(li)青(qing)和是(shi)由的拌合(he)物,然后加(jia)強防(fang)腐(fu)作用(yong)。
從外(wai)觀看鋼波紋涵(han)管(guan)(guan)(guan)壁表(biao)里均勻的(de)涂成了(le)黑(hei)管(guan)(guan)(guan)就能(neng)夠了(le)。但(dan)是要注(zhu)意等到(dao)瀝青(qing)想干以(yi)后才能(neng)回(hui)填。一般情況下瀝青(qing)涂層的(de)厚(hou)度要到(dao)達0.4-0.5mm。除此之(zhi)外(wai),還能(neng)采用加厚(hou)金屬波紋管(guan)(guan)(guan)涵(han)管(guan)(guan)(guan)壁的(de)方法,一般金屬波紋管(guan)(guan)(guan)涵(han)管(guan)(guan)(guan)壁每年(nian)蝕耗厚(hou)度為0.01-0.03mm。//hanihanbj.com/
