鋼波紋涵(han)管(guan)(guan)鋪設管(guan)(guan)槽應平整,無尖石(shi)和(he)軟土,為維護管(guan)(guan)道和(he)減少不均勻沉(chen)降,宜(yi)用大粒徑礦(kuang)礫加(jia)固。膠圈的(de)位置應放(fang)置在管(guan)(guan)道插(cha)(cha)口端的(de)個凹槽內(nei)。管(guan)(guan)道插(cha)(cha)口應順(shun)水流(liu),承(cheng)口逆水流(liu)方(fang)向(xiang)裝置。經(jing)實驗結果剖析(xi)得(de)出再生公(gong)路鋼波紋涵(han)管(guan)(guan)梁開裂彎矩較一般公(gong)路鋼波紋涵(han)管(guan)(guan)梁降低8.2%。
聚(ju)丙烯纖維公(gong)路(lu)鋼(gang)(gang)波紋(wen)(wen)涵(han)管(guan)(guan)梁(liang)(liang)開裂(lie)(lie)彎矩大于(yu)(yu)(yu)一(yi)般(ban)(ban)公(gong)路(lu)鋼(gang)(gang)波紋(wen)(wen)涵(han)管(guan)(guan)梁(liang)(liang)9.1%,聚(ju)丙烯纖維再(zai)生(sheng)(sheng)公(gong)路(lu)鋼(gang)(gang)波紋(wen)(wen)涵(han)管(guan)(guan)梁(liang)(liang)開裂(lie)(lie)彎矩較(jiao)再(zai)生(sheng)(sheng)公(gong)路(lu)鋼(gang)(gang)波紋(wen)(wen)涵(han)管(guan)(guan)梁(liang)(liang)前進14.1%;到達承載才干限狀況時,再(zai)生(sheng)(sheng)公(gong)路(lu)鋼(gang)(gang)波紋(wen)(wen)涵(han)管(guan)(guan)梁(liang)(liang)大裂(lie)(lie)縫寬度(du)高于(yu)(yu)(yu)一(yi)般(ban)(ban)公(gong)路(lu)鋼(gang)(gang)波紋(wen)(wen)涵(han)管(guan)(guan)梁(liang)(liang)16.1%,高于(yu)(yu)(yu)聚(ju)丙烯纖維再(zai)生(sheng)(sheng)公(gong)路(lu)鋼(gang)(gang)波紋(wen)(wen)涵(han)管(guan)(guan)梁(liang)(liang)23.2%,纖維阻裂(lie)(lie)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/
