使(shi)路外表沒有(you)伸縮縫，進(jin)步行(xing)車舒(shu)服性；有(you)利于改(gai)進(jin)軟土地基結構(gou)與路堤(di)交界處(chu)的(de)“錯臺”現象，進(jin)步行(xing)車安全(quan)性。波紋管涵(han)的(de)工(gong)(gong)(gong)后營(ying)運(yun)、養(yang)護成本(ben)低，工(gong)(gong)(gong)程(cheng)實際造價也低于同類跨徑的(de)橋梁、涵(han)洞(dong)。鋼(gang)板的(de)波形為(wei)進(jin)步板的(de)剛(gang)度(du)，板的(de)截面從平板加工(gong)(gong)(gong)成必定波幅的(de)波形狀(zhuang)，從加工(gong)(gong)(gong)、拼裝及板的(de)剛(gang)度(du)要求動(dong)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)照國內外同(tong)類產品的(de)(de)波(bo)(bo)(bo)(bo)形，管直(zhi)徑小(xiao)于(yu)1.5m的(de)(de)波(bo)(bo)(bo)(bo)距為(wei)(wei)125mm，波(bo)(bo)(bo)(bo)高(gao)為(wei)(wei)25mm；管直(zhi)徑大于(yu)1.5m的(de)(de)波(bo)(bo)(bo)(bo)距為(wei)(wei)200mm，波(bo)(bo)(bo)(bo)高(gao)為(wei)(wei)55mm。波(bo)(bo)(bo)(bo)紋(wen)為(wei)(wei)圓形全體管，選用整管節(jie)拼裝、法(fa)蘭(lan)螺栓(shuan)銜接(jie)。全體管銜接(jie)法(fa)蘭(lan)選用角鋼、鋼板(ban)制(zhi)造，波(bo)(bo)(bo)(bo)紋(wen)板(ban)焊接(jie)選用對(dui)焊接(jie)頭。

緊(jin)固(gu)件(jian)選用國標中的(de)(de)規范緊(jin)固(gu)件(jian)，其(qi)強(qiang)度和規格應(ying)滿(man)意(yi)力學要求，且(qie)不低于管材(cai)強(qiang)度要求。墊(dian)片與緊(jin)固(gu)件(jian)般(ban)配(pei)。螺栓與螺母均選用熱(re)浸鍍鋅處理。密(mi)封材(cai)料選用耐久性能較好的(de)(de)橡膠密(mi)封圈或(huo)方形石棉盤根(gen)密(mi)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/
