其間鋼(gang)質波紋板(ban)材選用(yong)國(guo)內(nei)普遍運(yun)用(yong)的A3或Q235-B熱(re)軋(ya)鋼(gang)板(ban),鋼(gang)板(ban)的理化目(mu)標要求到達GB700的有關要求,質量(liang)輕(qing)。以內(nei)徑1m的涵(han)管為例,鋼(gang)波紋涵(han)管每米質量(liang)為60~300kg(依(yi)波紋方式(shi)和(he)鋼(gang)板(ban)厚(hou)度而定),僅為鋼(gang)筋(jin)砼圓管涵(han)質量(liang)的百(bai)分之四到百(bai)分之二十,這給施工(gong)運(yun)送和(he)裝(zhuang)置帶來很大方便。
從資料與結構和功(gong)能(neng)的(de)本質關系上(shang)剖析,選用(yong)柔(rou)性、高強度(du)的(de)鋼波紋涵管洞,不只具有習慣地(di)基與根底變(bian)形的(de)能(neng)力。板(ban)的(de)尺度(du)和厚度(du)為便(bian)于(yu)板(ban)的(de)加工制造,結構的(de)裝置連(lian)接,進步板(ban)的(de)制造精度(du),板(ban)材的(de)尺度(du)宜(yi)習慣不同管徑的(de)需要,以構成系列化。板(ban)的(de)厚度(du)隨(sui)結構跨(kua)徑的(de)大(da)小改變(bian),板(ban)厚可(ke)選用(yong)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(hao)的(de)焊接性能(neng),滿(man)意波(bo)(bo)紋(wen)管(guan)在(zai)(zai)制造進(jin)程中(zhong)(zhong)的(de)焊接作業要(yao)求。管(guan)頂波(bo)(bo)峰(feng)與波(bo)(bo)谷處(chu)切向與軸向應(ying)(ying)力(li)(li)應(ying)(ying)變隨波(bo)(bo)構(gou)成拉壓替(ti)換的(de)改變規則(ze)。波(bo)(bo)峰(feng)和波(bo)(bo)谷在(zai)(zai)管(guan)頂、管(guan)底(di)、管(guan)側(ce)均為應(ying)(ying)力(li)(li)集中(zhong)(zhong)處(chu),各管(guan)徑等效應(ying)(ying)力(li)(li)的(de)方位與荷載密切相關(guan);大等效應(ying)(ying)力(li)(li)總體上隨管(guan)徑的(de)添(tian)加(jia)而添(tian)加(jia);隨著波(bo)(bo)紋(wen)管(guan)涵(han)洞(dong)的(de)壁厚添(tian)加(jia),大等效應(ying)(ying)力(li)(li)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/
