使路外表(biao)沒有伸縮(suo)縫，進步行車舒服性；有利于改進軟土地基結構與(yu)路堤(di)交界處的(de)(de)(de)“錯臺”現象(xiang)，進步行車安(an)全性。波(bo)紋管涵的(de)(de)(de)工后營運、養護成本低，工程實際造價也(ye)低于同(tong)類跨徑的(de)(de)(de)橋梁、涵洞(dong)。鋼板(ban)(ban)(ban)的(de)(de)(de)波(bo)形(xing)(xing)為(wei)進步板(ban)(ban)(ban)的(de)(de)(de)剛度，板(ban)(ban)(ban)的(de)(de)(de)截面從平板(ban)(ban)(ban)加工成必定波(bo)幅的(de)(de)(de)波(bo)形(xing)(xing)狀，從加工、拼裝及板(ban)(ban)(ban)的(de)(de)(de)剛度要求動身(shen)。

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.

并參照國內外(wai)同類產品的波(bo)(bo)形，管(guan)直徑小于(yu)1.5m的波(bo)(bo)距為125mm，波(bo)(bo)高(gao)(gao)為25mm；管(guan)直徑大于(yu)1.5m的波(bo)(bo)距為200mm，波(bo)(bo)高(gao)(gao)為55mm。波(bo)(bo)紋(wen)為圓形全體管(guan)，選用整(zheng)管(guan)節(jie)拼裝、法蘭螺栓銜接(jie)(jie)。全體管(guan)銜接(jie)(jie)法蘭選用角鋼、鋼板(ban)制造，波(bo)(bo)紋(wen)板(ban)焊接(jie)(jie)選用對焊接(jie)(jie)頭。

鋼波紋管

緊(jin)(jin)固(gu)件選用(yong)(yong)國標中的規范緊(jin)(jin)固(gu)件，其強度和規格(ge)應(ying)滿意(yi)力學要(yao)求，且不低于管材強度要(yao)求。墊片(pian)與緊(jin)(jin)固(gu)件般配。螺栓與螺母均選用(yong)(yong)熱浸(jin)鍍鋅處理。密封材料選用(yong)(yong)耐久性能較好的橡(xiang)膠密封圈(quan)或方(fang)形石棉(mian)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/
