鋼波(bo)紋涵管(guan)(guan)鋪設管(guan)(guan)槽應(ying)平(ping)整,無尖(jian)石和軟土,為維護管(guan)(guan)道和減少不均勻沉降,宜用大粒(li)徑礦礫加固。膠圈的位(wei)置應(ying)放置在管(guan)(guan)道插(cha)口(kou)端的個凹(ao)槽內。管(guan)(guan)道插(cha)口(kou)應(ying)順水(shui)流,承(cheng)口(kou)逆水(shui)流方(fang)向裝置。經實驗(yan)結果剖析得出再生公路鋼波(bo)紋涵管(guan)(guan)梁開(kai)裂彎矩較一(yi)般(ban)公路鋼波(bo)紋涵管(guan)(guan)梁降低8.2%。
聚丙烯(xi)(xi)(xi)纖維(wei)公路(lu)(lu)鋼(gang)波(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)梁(liang)開裂彎(wan)矩(ju)大于一般公路(lu)(lu)鋼(gang)波(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)梁(liang)9.1%,聚丙烯(xi)(xi)(xi)纖維(wei)再(zai)生(sheng)公路(lu)(lu)鋼(gang)波(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)梁(liang)開裂彎(wan)矩(ju)較再(zai)生(sheng)公路(lu)(lu)鋼(gang)波(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)梁(liang)前(qian)進14.1%;到達承載(zai)才干限狀況時,再(zai)生(sheng)公路(lu)(lu)鋼(gang)波(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)梁(liang)大裂縫(feng)寬度(du)高(gao)于一般公路(lu)(lu)鋼(gang)波(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)梁(liang)16.1%,高(gao)于聚丙烯(xi)(xi)(xi)纖維(wei)再(zai)生(sheng)公路(lu)(lu)鋼(gang)波(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)(guan)梁(liang)23.2%,纖維(wei)阻(zu)裂功能顯著。
公路鋼波紋涵管因再生骨料的天然缺陷引起再生公路鋼波紋涵管外部微裂紋、漏洞較多,使公路鋼波紋涵管抗壓強度、抗拉強度等功能降低,限制了再生公路鋼波紋涵管的運用。在再生公路鋼波紋涵管中參加聚丙烯纖維(公路鋼波紋涵管纖維)以研宄聚丙烯纖維對再生公路鋼波紋涵管梁受彎功能的影響。//hanihanbj.com/
