鋼制波紋管涵(han)(han)施工(gong)時,采(cai)用(yong)分段施工(gong)的辦(ban)法(fa),預先在原(yuan)拱(gong)涵(han)(han)基底用(yong)角(jiao)鋼并排兩根,長度依據涵(han)(han)長確(que)定。作鋼質涵(han)(han)管(guan)推(tui)進(jin)時的滑軌(gui),波(bo)紋涵(han)(han)管(guan)管(guan)徑依據工(gong)程需求可有分歧的規格,束裝管(guan)管(guan)徑為(wei)0.5m--2.5m;每(mei)節管(guan)長度3米左右。

鋼波紋涵管采用(yong)分段施工(gong)的(de)方(fang)法解析

采用內(外(wai))法蘭(lan)螺栓銜接(jie)。拼裝涵(han)管管徑為(wei)3m--8m。每(mei)個圓(yuan)周偏向(xiang)有4---15塊板構成,板與板搭接(jie)高強螺栓緊固。假如(ru)涵(han)長小于30米(mi),金屬波紋(wen)管涵(han)兩(liang)側與原涵(han)寬度大于80cm,可將整(zheng)道(dao)金屬波紋(wen)管涵(han)鄙(bi)人游或(huo)上(shang)游向(xiang)一端(duan)推進,就位今后,再進行(xing)一端(duan)擋墻的砌(qi)筑,周圍的回(hui)填(tian)(tian)任務(wu),可回(hui)填(tian)(tian)沙礫、碎(sui)石(shi)(shi)土,砌(qi)筑片(pian)(pian)石(shi)(shi)等,頂(ding)部(bu)采用漿(jiang)(jiang)砌(qi)片(pian)(pian)石(shi)(shi)或(huo)高壓泵送膨脹水(shui)泥沙漿(jiang)(jiang)。

假如涵(han)洞(dong)長大于30米(mi),鋼(gang)制波紋管(guan)涵(han)兩側與原涵(han)洞(dong)寬度(du)小(xiao)于80cm,可將(jiang)3m-6m長涵(han)管(guan)鄙(bi)人游或(huo)上游向一端推進(jin),就位今后(hou),可以將(jiang)其固(gu)定,砌筑頂端的片(pian)石(shi)端墻,鋼(gang)制波紋管(guan)涵(han)的另一端與涵(han)洞(dong)間的間距用沙袋或(huo)漿砌片(pian)石(shi)蓋住,寬度(du)50cm,然后(hou)開端回填。

兩(liang)側(ce)可用粗沙水密法(fa)(fa)密實(shi)或澆注混凝(ning)土震動棒搗實(shi);頂部(bu)采用高壓(ya)泵送(song)膨(peng)脹(zhang)水泥沙漿。該節管(guan)周圍填筑終了(le)今后,將第二節管(guan)運至,進行(xing)(xing)兩(liang)管(guan)的銜(xian)(xian)接,鋼制波紋管(guan)涵的銜(xian)(xian)接方法(fa)(fa)為(wei)內(nei)法(fa)(fa)蘭螺栓銜(xian)(xian)接,工(gong)人可在管(guan)內(nei)銜(xian)(xian)接。銜(xian)(xian)接終了(le)后,以上述一樣的辦法(fa)(fa)進行(xing)(xing)回填。
