使路(lu)外表沒有伸縮縫，進(jin)(jin)步行車舒服性；有利于改進(jin)(jin)軟土地基結構與路(lu)堤(di)交(jiao)界處的(de)(de)“錯臺”現(xian)象(xiang)，進(jin)(jin)步行車安全(quan)性。波(bo)紋管涵的(de)(de)工(gong)后營運、養(yang)護成(cheng)(cheng)本低(di)，工(gong)程實際造價也低(di)于同(tong)類跨徑的(de)(de)橋梁、涵洞。鋼板(ban)的(de)(de)波(bo)形為進(jin)(jin)步板(ban)的(de)(de)剛(gang)度(du)，板(ban)的(de)(de)截面從平板(ban)加(jia)工(gong)成(cheng)(cheng)必定波(bo)幅的(de)(de)波(bo)形狀(zhuang)，從加(jia)工(gong)、拼裝及板(ban)的(de)(de)剛(gang)度(du)要求動身。

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(can)照國內(nei)外同類(lei)產(chan)品的波(bo)形，管(guan)直(zhi)徑小于(yu)1.5m的波(bo)距為(wei)(wei)125mm，波(bo)高為(wei)(wei)25mm；管(guan)直(zhi)徑大于(yu)1.5m的波(bo)距為(wei)(wei)200mm，波(bo)高為(wei)(wei)55mm。波(bo)紋為(wei)(wei)圓形全體(ti)管(guan)，選用(yong)整(zheng)管(guan)節拼裝、法蘭(lan)螺栓銜(xian)接(jie)。全體(ti)管(guan)銜(xian)接(jie)法蘭(lan)選用(yong)角鋼、鋼板制造(zao)，波(bo)紋板焊接(jie)選用(yong)對焊接(jie)頭。

緊(jin)固件選用國標中的規(gui)范(fan)緊(jin)固件，其強度和規(gui)格(ge)應滿(man)意力(li)學要求(qiu)，且不低于(yu)管材強度要求(qiu)。墊(dian)片(pian)與(yu)緊(jin)固件般配。螺栓與(yu)螺母均選用熱(re)浸鍍(du)鋅處(chu)理。密封材料(liao)選用耐久性能較好的橡膠密封圈或方形石棉盤(pan)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，在加工后進行二次處理。為便于鋼板的加工制造，結構的裝置銜接，進步鋼板的制造精度，板材的尺寸宜適應不同管徑的需求，以形成系列化。板的厚度隨結構跨徑的巨細變化，鋼板厚可選用2.5-8mm。管壁及配套附件均經過熱浸鍍鋅處理，其鍍鋅層的平均厚度大于84um.涵管運至施工現場后，工地現場涂刷兩邊瀝青。//hanihanbj.com/
