鋼制波紋管涵(han)施工時,采用分段施工的辦法,預先在(zai)原拱涵(han)基底用角鋼(gang)并排兩根(gen),長(chang)度依據涵(han)長(chang)確定(ding)。作鋼(gang)質(zhi)涵(han)管(guan)(guan)(guan)推進時的滑軌(gui),波紋涵(han)管(guan)(guan)(guan)管(guan)(guan)(guan)徑依據工程需(xu)求可有分歧的規格(ge),束(shu)裝管(guan)(guan)(guan)管(guan)(guan)(guan)徑為0.5m--2.5m;每節管(guan)(guan)(guan)長(chang)度3米左右。
鋼波紋涵(han)管采用分段施工的方法解析
采用內(外)法(fa)蘭螺(luo)栓(shuan)銜(xian)接(jie)。拼裝涵(han)(han)管(guan)(guan)管(guan)(guan)徑為(wei)3m--8m。每個圓周偏向有4---15塊板(ban)(ban)構成,板(ban)(ban)與(yu)板(ban)(ban)搭(da)接(jie)高強(qiang)螺(luo)栓(shuan)緊固(gu)。假如涵(han)(han)長(chang)小于30米,金屬波紋管(guan)(guan)涵(han)(han)兩側與(yu)原涵(han)(han)寬(kuan)度大于80cm,可(ke)將整(zheng)道金屬波紋管(guan)(guan)涵(han)(han)鄙(bi)人游(you)或上游(you)向一(yi)(yi)端推(tui)進(jin),就(jiu)位今后,再進(jin)行(xing)一(yi)(yi)端擋墻的(de)砌(qi)筑,周圍的(de)回填(tian)任務,可(ke)回填(tian)沙礫、碎石(shi)(shi)土,砌(qi)筑片(pian)(pian)石(shi)(shi)等(deng),頂部采用漿砌(qi)片(pian)(pian)石(shi)(shi)或高壓(ya)泵送膨(peng)脹水泥沙漿。
假如(ru)涵(han)洞(dong)(dong)長大于30米(mi),鋼制波(bo)紋(wen)管(guan)涵(han)兩側(ce)與原涵(han)洞(dong)(dong)寬度(du)小于80cm,可將3m-6m長涵(han)管(guan)鄙人游(you)或上游(you)向一(yi)(yi)端(duan)(duan)推進,就位今(jin)后(hou),可以將其固定,砌(qi)(qi)筑(zhu)頂(ding)端(duan)(duan)的(de)片石(shi)端(duan)(duan)墻,鋼制波(bo)紋(wen)管(guan)涵(han)的(de)另(ling)一(yi)(yi)端(duan)(duan)與涵(han)洞(dong)(dong)間的(de)間距用(yong)沙(sha)袋或漿砌(qi)(qi)片石(shi)蓋住,寬度(du)50cm,然(ran)后(hou)開端(duan)(duan)回填。
兩側可(ke)用粗沙水(shui)密(mi)法(fa)(fa)密(mi)實(shi)或(huo)澆(jiao)注混凝土震動棒搗實(shi);頂(ding)部采用高(gao)壓泵送膨脹水(shui)泥沙漿。該節(jie)管周圍填(tian)筑終(zhong)了(le)(le)今后,將第(di)二節(jie)管運(yun)至,進行(xing)兩管的(de)銜(xian)(xian)(xian)接,鋼制波紋管涵的(de)銜(xian)(xian)(xian)接方法(fa)(fa)為內法(fa)(fa)蘭螺栓銜(xian)(xian)(xian)接,工人(ren)可(ke)在管內銜(xian)(xian)(xian)接。銜(xian)(xian)(xian)接終(zhong)了(le)(le)后,以(yi)上(shang)述一(yi)樣的(de)辦(ban)法(fa)(fa)進行(xing)回(hui)填(tian)。

依(yi)次進行(xing),完成整道(dao)(dao)金(jin)屬波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)的(de)建筑(zhu)任務。波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)是道(dao)(dao)路建設施(shi)工(gong)中需要用到的(de)一(yi)種涵(han)(han)管(guan)(guan)(guan),其在(zai)公路施(shi)工(gong)時(shi)所(suo)應(ying)(ying)用的(de)范圍也是極廣的(de),波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)又分(fen)(fen)為金(jin)屬波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)與鋼波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han),根據(ju)外形不同還有螺(luo)旋波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)和異型(xing)波(bo)(bo)紋管(guan)(guan)(guan)涵(han)(han)的(de)分(fen)(fen)類,這些都在(zai)道(dao)(dao)路施(shi)工(gong)中普遍應(ying)(ying)用。(hanihanbj.com)
