鋼波紋涵管耐熱耐寒性能好在(zai)(zai)-30℃狀態下,仍具有良(liang)好的(de)韌性和極高的(de)強(qiang)度,可(ke)(ke)在(zai)(zai)-50℃-80℃的(de)范(fan)圍內長期使(shi)(shi)用(yong)(yong)(yong),采(cai)用(yong)(yong)(yong)特殊配方的(de)樹脂還(huan)可(ke)(ke)110℃時使(shi)(shi)用(yong)(yong)(yong)。固化(hua)后防污抗性在(zai)(zai)使(shi)(shi)用(yong)(yong)(yong)過程中不結垢(gou)、不生銹(xiu)、不會被海(hai)洋或污水中的(de)貝(bei)類,菌(jun)類等(deng)微生物(wu)玷污蛀附。
介紹一下鋼波紋涵管常(chang)見的(de)安裝方式
根據首件工(gong)(gong)程施(shi)工(gong)(gong)情況(kuang),各種保證體(ti)系運(yun)行正常,保證措(cuo)施(shi)齊全(quan)(quan)。金屬波紋涵(han)(han)管(guan)是一種柔性(xing)結(jie)構,它建成(cheng)后與周(zhou)圍(wei)材料體(ti)形(xing)(xing)成(cheng)一種組合(he)結(jie)構,共同(tong)受力,波紋管(guan)涵(han)(han)楔形(xing)(xing)部(bu)及(ji)兩側(ce)的(de)回(hui)填施(shi)工(gong)(gong)很關(guan)鍵,如果回(hui)填不密實或(huo)有(you)(you)(you)楔形(xing)(xing)部(bu)中空或(huo)局(ju)部(bu)有(you)(you)(you)大石塊直接作用(yong)于管(guan)體(ti),將出現局(ju)部(bu)有(you)(you)(you)較(jiao)大變形(xing)(xing)或(huo)局(ju)部(bu)有(you)(you)(you)凸(tu)起,存在安全(quan)(quan)隱患,嚴重的(de)可能會造成(cheng)質量事故,所(suo)以(yi)波紋管(guan)涵(han)(han)兩側(ce)及(ji)楔形(xing)(xing)部(bu)的(de)回(hui)填質量在施(shi)工(gong)(gong)中要嚴格控(kong)制。
鋼(gang)波(bo)紋涵管
波紋管在(zai)儀(yi)器(qi)外(wai)表中運(yun)用,主要用途是作為壓力丈量(liang)外(wai)表的(de)(de)(de)丈量(liang)元件,將壓力轉換成(cheng)位(wei)移或(huo)力。波紋管管壁(bi)較(jiao)薄,靈敏度較(jiao)高(gao),丈量(liang)規模(mo)為數十帕至數十兆(zhao)帕。它的(de)(de)(de)開口端固定(ding),密封端處于自由狀況,并運(yun)用輔(fu)佐(zuo)的(de)(de)(de)螺旋彈(dan)簧或(huo)簧片添加彈(dan)性。作業(ye)時在(zai)內部壓力的(de)(de)(de)效果下沿管子長度方向伸長,使活(huo)(huo)動(dong)端發(fa)生與(yu)壓力成(cheng)必定(ding)關系的(de)(de)(de)位(wei)移。活(huo)(huo)動(dong)端帶(dai)動(dong)指針即可(ke)直接指示壓力的(de)(de)(de)巨細。
有利于改善軟土地基結(jie)構(gou)物與(yu)路堤交界處的“錯臺”現象,提高(gao)行車的舒(shu)適度與(yu)安全性(xing),減少工(gong)后營運(yun)、養護(hu)成本。耐老化:管(guan)材通(tong)常(chang)為黑色,可(ke)承受存放和施(shi)工(gong)過程(cheng)中(zhong)太陽(yang)的直曬;管(guan)材在(zai)(zai)-60℃環(huan)境中(zhong)不會被凍(dong)裂(lie)及膨(peng)脹漏水(shui);重量輕:便(bian)于運(yun)輸,施(shi)工(gong)方(fang)便(bian),是水(shui)泥(ni)管(guan)重量的1/8,埋管(guan)只需挖土機,不需大型設備;連接方(fang)便(bian):管(guan)材可(ke)先在(zai)(zai)溝外連接,用(yong)(yong)挖土機推(tui)到溝中(zhong),減少工(gong)程(cheng)時間(jian)和費用(yong)(yong);比鋼管(guan)、水(shui)泥(ni)管(guan)耐磨(mo),生活水(shui)廢渣(zha)通(tong)運(yun)能力強;
可(ke)以加工(gong)成(cheng)弧行(xing),拱型(xing)(xing),橢圓三(san)通等異型(xing)(xing)結構,便(bian)于曲線施(shi)工(gong)。施(shi)工(gong)工(gong)期短,土建與型(xing)(xing)材安裝可(ke)分開實(shi)施(shi),然后進行(xing)整體拼裝。使(shi)路表面(mian)沒有伸縮(suo)縫,提(ti)高行(xing)車舒適性。進行(xing)工(gong)廠集中化生產,有利降低成(cheng)本,控(kong)制(zhi)質量。生產周期短。施(shi)工(gong)不受(shou)季節限制(zhi),不受(shou)環境(jing)影響,現(xian)場安裝方便(bian),不需使(shi)用大型(xing)(xing)設備。
如(ru)地(di)基承載力不能達到要求,應(ying)進行其他(ta)加固地(di)基處(chu)理;在南方多雨膨脹土(tu)地(di)區使用時,如(ru)遇(yu)連(lian)續(xu)降(jiang)雨天氣,應(ying)采取地(di)基防(fang)水處(chu)理,在基礎(chu)底(di)部(bu)及管頂以上100cm增設防(fang)水土(tu)工(gong)(gong)布,以防(fang)雨水浸泡地(di)基造成沉降(jiang)。金屬波(bo)紋(wen)(wen)管涵基礎(chu)施(shi)工(gong)(gong):根據(ju)首件(jian)工(gong)(gong)程施(shi)工(gong)(gong)情況,波(bo)紋(wen)(wen)管的管身要設置預留拱度。想了解更多關于鋼(gang)波(bo)紋(wen)(wen)涵管的新(xin)聞動態(tai)請點(dian)擊:hanihanbj.com
