密封材料采用耐久機能較好的橡膠密封圈或方形石棉盤根密封條。鋼波紋涵管接替鋼筋水泥施行涵洞(dong)動工(gong)，無論從動工(gong)周期、動工(gong)造(zao)價、環保意義等方面(mian)都(dou)有其不(bu)可以相比的(de)優良性，且用金屬波(bo)紋涵管施行涵洞(dong)動工(gong)，可大(da)(da)大(da)(da)增(zeng)長道路橋(qiao)式起重機的(de)舒(shu)程度適當與安全性，防止道路中涵洞(dong)的(de)“錯臺跳車”顯露原形，有匡助于解決西北及我國陰冷地(di)區霜凍害(hai)對(dui)砼管涵結構的(de)毀傷題目。

鋼波紋涵管為何采用現在這樣的構造處理？

管(guan)(guan)壁及配(pei)套附件(jian)均經由熱浸鍍鋅處理，其鍍鋅層的均勻厚度大于84um.涵管(guan)(guan)運(yun)至施工現場后，工地(di)現場涂刷兩邊瀝青(qing)。

構造處(chu)(chu)理(li)(li)(li)：波紋為(wei)圓形(xing)整(zheng)體管(guan)(guan)，采用(yong)整(zheng)管(guan)(guan)節拼裝、法蘭螺(luo)栓連接(jie)。金屬(shu)波紋涵管(guan)(guan)加(jia)工后須采用(yong)熱鍍(du)鋅等防腐處(chu)(chu)理(li)(li)(li)。采用(yong)鍍(du)鋅鋼板加(jia)工的，在加(jia)工后必需進行(xing)二次處(chu)(chu)理(li)(li)(li)。整(zheng)體管(guan)(guan)連接(jie)法蘭采用(yong)角鋼、鋼板制作(zuo)，波紋板焊(han)接(jie)采用(yong)對(dui)焊(han)接(jie)頭(tou)。緊固件采用(yong)國標(biao)中(zhong)的尺度緊固件，其強(qiang)度和規格應知足力學要求(qiu)，且不低于(yu)管(guan)(guan)材強(qiang)度要求(qiu)。墊片與緊固件相配。螺(luo)栓與螺(luo)母均采用(yong)熱浸鍍(du)鋅處(chu)(chu)理(li)(li)(li)。
