鋼波紋涵管耐(nai)熱耐(nai)寒性(xing)能好(hao)在-30℃狀(zhuang)態(tai)下,仍具有(you)良(liang)好(hao)的(de)韌性(xing)和(he)極高(gao)的(de)強(qiang)度,可在-50℃-80℃的(de)范圍內(nei)長期使用(yong),采用(yong)特殊配方的(de)樹(shu)脂還可110℃時使用(yong)。固化后防污(wu)抗性(xing)在使用(yong)過程中(zhong)不(bu)結垢(gou)、不(bu)生(sheng)(sheng)銹、不(bu)會(hui)被海洋或(huo)污(wu)水(shui)中(zhong)的(de)貝類(lei),菌(jun)類(lei)等微生(sheng)(sheng)物玷污(wu)蛀附。
介紹一下鋼(gang)波(bo)紋涵(han)管常見的安裝方式
根據首(shou)件工程(cheng)施工情(qing)況,各種保證體系運行正常,保證措施齊全(quan)(quan)。金屬波(bo)(bo)紋(wen)涵管是一(yi)種柔性結構,它建(jian)成(cheng)后與周圍材料體形(xing)(xing)成(cheng)一(yi)種組合(he)結構,共同受力(li),波(bo)(bo)紋(wen)管涵楔形(xing)(xing)部(bu)(bu)及(ji)(ji)兩(liang)側(ce)的回(hui)填施工很(hen)關鍵,如果回(hui)填不密(mi)實或有楔形(xing)(xing)部(bu)(bu)中(zhong)(zhong)空或局(ju)部(bu)(bu)有大石塊(kuai)直(zhi)接作用于(yu)管體,將(jiang)出現局(ju)部(bu)(bu)有較大變(bian)形(xing)(xing)或局(ju)部(bu)(bu)有凸(tu)起,存在安全(quan)(quan)隱患,嚴重的可能會造(zao)成(cheng)質(zhi)量(liang)事故,所以(yi)波(bo)(bo)紋(wen)管涵兩(liang)側(ce)及(ji)(ji)楔形(xing)(xing)部(bu)(bu)的回(hui)填質(zhi)量(liang)在施工中(zhong)(zhong)要嚴格控(kong)制(zhi)。
鋼波紋涵(han)管
波紋(wen)管(guan)(guan)在儀(yi)器外表中運(yun)(yun)用(yong),主要用(yong)途是作為壓(ya)力(li)(li)丈量外表的丈量元件(jian),將(jiang)壓(ya)力(li)(li)轉(zhuan)換成(cheng)位移(yi)或(huo)力(li)(li)。波紋(wen)管(guan)(guan)管(guan)(guan)壁較(jiao)(jiao)薄,靈敏度較(jiao)(jiao)高(gao),丈量規模為數(shu)十帕(pa)至數(shu)十兆(zhao)帕(pa)。它的開口端固定(ding),密封(feng)端處于自由狀況,并運(yun)(yun)用(yong)輔佐的螺旋彈(dan)簧或(huo)簧片(pian)添加(jia)彈(dan)性(xing)。作業時在內部壓(ya)力(li)(li)的效果下(xia)沿管(guan)(guan)子長度方向伸(shen)長,使活動端發生與壓(ya)力(li)(li)成(cheng)必(bi)定(ding)關系的位移(yi)。活動端帶動指(zhi)針(zhen)即(ji)可直接指(zhi)示壓(ya)力(li)(li)的巨細。
有利于(yu)改善軟土地(di)基結構物與(yu)路堤交界處的(de)“錯臺”現象,提(ti)高行車(che)的(de)舒適度與(yu)安(an)全(quan)性,減少工(gong)(gong)后營運、養護成本。耐老化(hua):管(guan)(guan)材通常為黑(hei)色,可(ke)承(cheng)受存放和施工(gong)(gong)過程(cheng)中太(tai)陽(yang)的(de)直(zhi)曬;管(guan)(guan)材在-60℃環境中不會被凍裂及膨脹(zhang)漏水;重(zhong)量(liang)輕:便(bian)(bian)于(yu)運輸,施工(gong)(gong)方(fang)便(bian)(bian),是水泥管(guan)(guan)重(zhong)量(liang)的(de)1/8,埋管(guan)(guan)只需挖土機(ji),不需大型設備;連接(jie)方(fang)便(bian)(bian):管(guan)(guan)材可(ke)先在溝外連接(jie),用挖土機(ji)推(tui)到溝中,減少工(gong)(gong)程(cheng)時(shi)間和費用;比(bi)鋼管(guan)(guan)、水泥管(guan)(guan)耐磨(mo),生活水廢渣(zha)通運能力強;
可(ke)以加工(gong)(gong)(gong)成(cheng)弧(hu)行,拱型,橢圓三通等異型結構,便于曲線(xian)施(shi)(shi)工(gong)(gong)(gong)。施(shi)(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)期(qi)短,土建(jian)與型材安裝(zhuang)可(ke)分開實施(shi)(shi),然后進(jin)行整體拼裝(zhuang)。使路表(biao)面沒有(you)伸縮縫,提高行車舒適性。進(jin)行工(gong)(gong)(gong)廠集中化生(sheng)產,有(you)利降低成(cheng)本,控制質量。生(sheng)產周期(qi)短。施(shi)(shi)工(gong)(gong)(gong)不受(shou)季節限制,不受(shou)環境影(ying)響,現場安裝(zhuang)方便,不需使用大型設備。
如(ru)地(di)基(ji)承載力不能(neng)達到要(yao)求,應(ying)(ying)進行其他加固地(di)基(ji)處理;在南方多(duo)雨膨脹土地(di)區使(shi)用時,如(ru)遇連續降雨天氣,應(ying)(ying)采取地(di)基(ji)防(fang)水處理,在基(ji)礎(chu)底部(bu)及管(guan)頂以(yi)上100cm增(zeng)設防(fang)水土工(gong)(gong)布,以(yi)防(fang)雨水浸(jin)泡地(di)基(ji)造(zao)成沉降。金(jin)屬波紋(wen)管(guan)涵(han)基(ji)礎(chu)施(shi)工(gong)(gong):根據(ju)首件工(gong)(gong)程(cheng)施(shi)工(gong)(gong)情(qing)況(kuang),波紋(wen)管(guan)的(de)(de)管(guan)身要(yao)設置預留拱(gong)度。想(xiang)了解更多(duo)關于鋼波紋(wen)涵(han)管(guan)的(de)(de)新聞(wen)動(dong)態請點(dian)擊:hanihanbj.com
