鋼波紋涵管出廠時,要(yao)(yao)附有(you)產品質量合格證書,沒有(you)合格證書的(de)(de)(de)一概不能(neng)出廠。鋼波紋(wen)涵管(guan)運到施工現場后,要(yao)(yao)逐(zhu)塊檢查,凡在運輸過(guo)(guo)程中變形的(de)(de)(de)鋼板不得用。基礎的(de)(de)(de)地基承載力要(yao)(yao)滿意沒計要(yao)(yao)求,嚴禁超挖回填虛(xu)土超過(guo)(guo)以及(ji)標高(gao)控(kong)制。

鋼(gang)波(bo)紋涵(han)管在裝(zhuang)置(zhi)時(shi)(shi),拼接處要(yao)清(qing)理潔(jie)凈(jing)。以保證拼縫搭接緊密(mi)。在實踐條件答應(ying)的(de)情況下(xia),應(ying)先考慮采用改動鋼(gang)波(bo)紋涵(han)管管道(dao)的(de)走向和繃簧支吊架的(de)方法來添(tian)(tian)加管道(dao)的(de)柔性。一般情況下(xia),當(dang)兩(liang)個固(gu)定點(dian)位(wei)置(zhi)是一定時(shi)(shi),添(tian)(tian)加鋼(gang)波(bo)紋涵(han)管系長度和彎(wan)頭數量能夠(gou)添(tian)(tian)加管道(dao)的(de)柔性。
當鋼波紋涵管在某一方向的剛(gang)度(du)(du)過(guo)大時(shi),添加與其垂(chui)直(zhi)方向的管道(dao)長度(du)(du)可減小(xiao)管涵的剛(gang)度(du)(du)。選用(yong)繃簧支吊架能(neng)夠使支吊架處存(cun)在垂(chui)直(zhi)位移(yi),將約束放松,添加其柔(rou)性。當鋼波紋涵管管徑較(jiao)大、場地受限制而且所需求的補(bu)償量較(jiao)大時(shi),能(neng)夠考慮用(yong)波紋管膨(peng)脹(zhang)節來添加管道(dao)柔(rou)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(bo)紋(wen)管(guan)(guan)膨脹(zhang)節(jie)制作雜亂,價格(ge)偏高,它適(shi)用(yong)于(yu)低壓大直徑管(guan)(guan)道(dao)(dao),但波(bo)紋(wen)管(guan)(guan)膨脹(zhang)節(jie)是(shi)管(guan)(guan)道(dao)(dao)中的(de)薄弱環節(jie),應盡量防止采(cai)用(yong)。能(neng)夠在金屬波(bo)紋(wen)管(guan)(guan)涵表(biao)里管(guan)(guan)壁涂上或(huo)(huo)者噴上含有(you)石棉纖維的(de)厚瀝青。或(huo)(huo)者是(shi)涂刷兩邊(bian)瀝青和是(shi)由的(de)拌合物,然后加強防腐作用(yong)。
從外(wai)觀看鋼波紋涵管(guan)壁表里均勻的涂成了黑管(guan)就(jiu)能夠了。但(dan)是要(yao)注意等到(dao)瀝青想(xiang)干以后才能回填。一般情況下(xia)瀝青涂層的厚度要(yao)到(dao)達(da)0.4-0.5mm。除此之外(wai),還能采用加厚金屬(shu)波紋管(guan)涵管(guan)壁的方法,一般金屬(shu)波紋管(guan)涵管(guan)壁每年蝕耗厚度為0.01-0.03mm。//hanihanbj.com/
