鋼波紋涵管有圓形、橢圓形、半(ban)圓形等，進出口也可按照邊坡比例做成斜(xie)口，加(jia)工(gong)波(bo)紋管(guan)管(guan)徑規(gui)模Φ0.5m～Φ8m，管(guan)壁(bi)厚(hou)度為3mm～7mm，能夠滿(man)意填土(tu)0.5m～40m厚(hou)的需要(yao)。鋼波(bo)紋涵管(guan)具有工(gong)期(qi)短、重量輕、裝置方(fang)便(bian)、耐久性好、工(gong)程造(zao)價低、抗變形能力強、減少通(tong)車后維護本(ben)錢等特點。

從(cong)資料與結構(gou)和功能的本質關系上(shang)剖析，選用柔(rou)性(xing)、高強度(du)(du)的鋼波紋(wen)涵管洞，不(bu)只(zhi)具(ju)有習(xi)慣地基(ji)與根(gen)底變形的能力。板(ban)的尺度(du)(du)和厚度(du)(du)為便于板(ban)的加工制造(zao)，結構(gou)的裝(zhuang)置連(lian)接，進步板(ban)的制造(zao)精度(du)(du)，板(ban)材(cai)的尺度(du)(du)宜(yi)習(xi)慣不(bu)同管徑的需要(yao)，以構(gou)成(cheng)系列(lie)化。板(ban)的厚度(du)(du)隨結構(gou)跨徑的大小改變，板(ban)厚可選用2.5-8mm。

Based on the analysis of the essential relationship between data and structure and function, the selection of flexible and high-strength steel corrugated culvert tunnel not only has the ability to get used to the deformation of foundation and foundation. Size and thickness of plate in order to facilitate the processing and manufacturing of plate, the device connection of structure and improve the manufacturing accuracy of plate, the size of plate should be used to the needs of different pipe diameters to form serialization. The thickness of the plate changes with the size of the structural span, and the plate thickness can be 2.5-8mm.

良好的(de)焊接性能(neng)，滿意波(bo)(bo)紋管(guan)在制(zhi)造進程中的(de)焊接作業要求。管(guan)頂(ding)波(bo)(bo)峰與(yu)(yu)波(bo)(bo)谷處(chu)切向與(yu)(yu)軸向應(ying)(ying)力應(ying)(ying)變(bian)隨(sui)(sui)波(bo)(bo)構成拉壓(ya)替換的(de)改變(bian)規則。波(bo)(bo)峰和波(bo)(bo)谷在管(guan)頂(ding)、管(guan)底、管(guan)側均為(wei)應(ying)(ying)力集中處(chu)，各管(guan)徑(jing)等效應(ying)(ying)力的(de)方位與(yu)(yu)荷載密(mi)切相關；大等效應(ying)(ying)力總體上(shang)隨(sui)(sui)管(guan)徑(jing)的(de)添加(jia)(jia)而添加(jia)(jia)；隨(sui)(sui)著波(bo)(bo)紋管(guan)涵洞的(de)壁厚(hou)添加(jia)(jia)，大等效應(ying)(ying)力呈對數減小。

如果涵洞規劃得太小和太接近于地表特別是在露出的當地，并且水流速度緩慢，則在北部地區的冬季簡單凍住，還要阻塞。這能夠得到彌補，方法所以添加涵洞的坡度，選用無底的木制涵洞或在冰冷時節接近時，把涵洞進口端用軟樹技鋪蓋。//hanihanbj.com/
