鋼制波紋管涵(han)(han)施工時(shi),采用分段施工的辦法(fa),預先在原拱涵(han)(han)基底用角鋼并排兩(liang)根,長(chang)(chang)度依據(ju)(ju)涵(han)(han)長(chang)(chang)確定。作鋼質涵(han)(han)管(guan)(guan)推進時(shi)的滑軌,波紋(wen)涵(han)(han)管(guan)(guan)管(guan)(guan)徑依據(ju)(ju)工程(cheng)需求可有(you)分歧的規格,束裝管(guan)(guan)管(guan)(guan)徑為0.5m--2.5m;每節管(guan)(guan)長(chang)(chang)度3米左右。
鋼波紋涵管采(cai)用(yong)分(fen)段施工的(de)方法解(jie)析(xi)
采(cai)用內(nei)(外)法蘭螺(luo)(luo)栓(shuan)銜(xian)接。拼裝(zhuang)涵(han)管(guan)(guan)管(guan)(guan)徑(jing)為3m--8m。每個圓周偏向有(you)4---15塊板構成,板與(yu)板搭接高強螺(luo)(luo)栓(shuan)緊固。假如涵(han)長(chang)小于(yu)30米,金屬(shu)波(bo)紋(wen)管(guan)(guan)涵(han)兩側與(yu)原(yuan)涵(han)寬(kuan)度大于(yu)80cm,可將整道金屬(shu)波(bo)紋(wen)管(guan)(guan)涵(han)鄙人(ren)游或上游向一端推進,就位(wei)今后,再進行(xing)一端擋墻的砌筑,周圍的回填(tian)任務,可回填(tian)沙(sha)礫、碎(sui)石土(tu),砌筑片石等,頂部采(cai)用漿砌片石或高壓泵送膨脹(zhang)水泥沙(sha)漿。
假如涵(han)洞(dong)長大于30米,鋼制(zhi)波紋(wen)管(guan)涵(han)兩側與原涵(han)洞(dong)寬度(du)小于80cm,可將3m-6m長涵(han)管(guan)鄙人游(you)或上(shang)游(you)向一(yi)端推進(jin),就位今(jin)后,可以將其固定(ding),砌(qi)筑頂端的片石端墻,鋼制(zhi)波紋(wen)管(guan)涵(han)的另一(yi)端與涵(han)洞(dong)間的間距用沙袋或漿砌(qi)片石蓋住(zhu),寬度(du)50cm,然后開端回填。
兩側可(ke)用粗沙水密法(fa)密實(shi)(shi)或澆(jiao)注混凝土(tu)震動棒搗實(shi)(shi);頂部采(cai)用高壓泵送膨脹水泥沙漿。該節(jie)管(guan)周圍填筑終(zhong)了今(jin)后(hou),將第(di)二節(jie)管(guan)運至,進行(xing)兩管(guan)的銜接,鋼制波紋管(guan)涵的銜接方法(fa)為內(nei)法(fa)蘭螺栓銜接,工人可(ke)在管(guan)內(nei)銜接。銜接終(zhong)了后(hou),以上述(shu)一樣的辦法(fa)進行(xing)回(hui)填。
鋼(gang)波紋(wen)涵管
依次進行,完成整道(dao)(dao)金屬波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)的建筑任務。波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)是道(dao)(dao)路建設施(shi)(shi)(shi)工中(zhong)需要用到(dao)的一種涵(han)(han)管(guan)(guan),其在公路施(shi)(shi)(shi)工時所應用的范圍也是極廣的,波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)又分(fen)為金屬波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)與鋼波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han),根(gen)據外形不同還有螺旋(xuan)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)和異型波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)的分(fen)類,這些都在道(dao)(dao)路施(shi)(shi)(shi)工中(zhong)普遍應用。(hanihanbj.com)
