鋼波紋管涵選用規(guī)范化設(shè)計(jì)、集中化生產(chǎn)，現(xiàn)場(chǎng)裝置土建與型材可分開施行，減少或底子放棄了常規(guī)建材，工期短，環(huán)保意義深遠(yuǎn)。鋼制波紋管涵的結(jié)構(gòu)受力情況合理，荷載散布均勻，并具有必定的抗變形才能，能解決北方冰冷區(qū)域（霜凍）對(duì)橋梁和管涵砼結(jié)構(gòu)的破壞問題。

使路外表沒有伸縮縫，進(jìn)步行車舒服性；有利于改進(jìn)軟土地基結(jié)構(gòu)與路堤交界處的“錯(cuò)臺(tái)”現(xiàn)象，進(jìn)步行車安全性。波紋管涵的工后營(yíng)運(yùn)、養(yǎng)護(hù)成本低，工程實(shí)際造價(jià)也低于同類跨徑的橋梁、涵洞。鋼板的波形為進(jìn)步板的剛度，板的截面從平板加工成必定波幅的波形狀，從加工、拼裝及板的剛度要求動(dòng)身。

Make the road surface free of expansion joints and improve driving comfort; It is beneficial to improve the "staggered platform" phenomenon at the junction of soft soil foundation structure and embankment and improve driving safety. The post construction operation and maintenance cost of corrugated pipe culvert is low, and the actual project cost is lower than that of bridges and culverts with similar spans. The waveform of the steel plate is to improve the stiffness of the plate. The section of the plate is processed from the plate into a wave shape with a certain amplitude, and starts from the requirements of processing, assembly and plate stiffness.

并參照國(guó)內(nèi)外同類產(chǎn)品的波形，管直徑小于1.5m的波距為125mm，波高為25mm；管直徑大于1.5m的波距為200mm，波高為55mm。波紋為圓形全體管，選用整管節(jié)拼裝、法蘭螺栓銜接。全體管銜接法蘭選用角鋼、鋼板制造，波紋板焊接選用對(duì)焊接頭。

緊固件選用國(guó)標(biāo)中的規(guī)范緊固件，其強(qiáng)度和規(guī)格應(yīng)滿意力學(xué)要求，且不低于管材強(qiáng)度要求。墊片與緊固件般配。螺栓與螺母均選用熱浸鍍鋅處理。密封材料選用耐久性能較好的橡膠密封圈或方形石棉盤根密封條。

鋼波紋管涵加工后須選用熱鍍鋅等防腐處理。選用鍍鋅鋼板加工的，在加工后進(jìn)行二次處理。為便于鋼板的加工制造，結(jié)構(gòu)的裝置銜接，進(jìn)步鋼板的制造精度，板材的尺寸宜適應(yīng)不同管徑的需求，以形成系列化。板的厚度隨結(jié)構(gòu)跨徑的巨細(xì)變化，鋼板厚可選用2.5-8mm。管壁及配套附件均經(jīng)過熱浸鍍鋅處理，其鍍鋅層的平均厚度大于84um.涵管運(yùn)至施工現(xiàn)場(chǎng)后，工地現(xiàn)場(chǎng)涂刷兩邊瀝青。http://topusaedu.com.cn/
