【收藏】鋼(gang)波(bo)紋管(guan)安裝方法

1、涵洞施(shi)工前，準(zhun)備好相關(guan)材料、人員和(he)設備進場，做好施(shi)工過程中(zhong)的安全防護，并用(yong)圍欄保護路(lu)基邊坡，使(shi)石塊等物體滑下傷(shang)人

2基(ji)礎處理：回(hui)填砂(sha)(sha)礫或片石(shi)混凝(ning)土，平整基(ji)層，可更換厚度為30-50cm的(de)砂(sha)(sha)礫石(shi)材(cai)料，流水縱坡宜在3%左右，并可確定每個涵洞的(de)中(zhong)線和(he)邊線

3。在(zai)鋼波紋(wen)管(guan)(guan)的施工過程(cheng)中，采用分段施工的方(fang)法。在(zai)原拱涵(han)(han)基礎上提前并排(pai)布(bu)置兩根角(jiao)鋼，長度(du)(du)根據(ju)涵(han)(han)洞長度(du)(du)確(que)定(ding)，可作(zuo)為涵(han)(han)管(guan)(guan)推壓時的滑軌。鋼波紋(wen)管(guan)(guan)的管(guan)(guan)徑管(guan)(guan)涵(han)(han)可根據(ju)項目需要有不同的規格。組裝管(guan)(guan)道直(zhi)(zhi)徑為0.5m-2.5m，每段長度(du)(du)為3.06M。采用內（外）法蘭螺栓(shuan)(shuan)連接，組裝管(guan)(guan)道直(zhi)(zhi)徑3m-8m，板間搭接螺栓(shuan)(shuan)緊固。

4如果(guo)涵(han)(han)洞(dong)長度(du)小于30m，鋼(gang)波(bo)(bo)(bo)紋管(guan)涵(han)(han)兩(liang)(liang)側與原(yuan)涵(han)(han)洞(dong)之間(jian)的寬度(du)大于80cm，可將整個鋼(gang)波(bo)(bo)(bo)紋管(guan)涵(han)(han)推至下游(you)或上(shang)游(you)一端。就(jiu)位后(hou)(hou)，可進行(xing)(xing)一端擋土(tu)墻的砌筑。周(zhou)圍(wei)(wei)回(hui)填可采(cai)(cai)用(yong)(yong)礫石、碎石土(tu)、漿砌片石等進行(xing)(xing)回(hui)填。涵(han)(han)洞(dong)長度(du)大于30m，鋼(gang)波(bo)(bo)(bo)紋管(guan)涵(han)(han)兩(liang)(liang)側寬度(du)小于80cm時，頂部(bu)(bu)應采(cai)(cai)用(yong)(yong)漿砌片石或高壓(ya)泵送膨脹(zhang)水(shui)泥砂(sha)漿，3m-6m長的涵(han)(han)管(guan)可推至下游(you)或上(shang)游(you)的一端。就(jiu)位后(hou)(hou)即可進行(xing)(xing)固定，并(bing)可修建頂部(bu)(bu)毛石端墻。鋼(gang)波(bo)(bo)(bo)紋管(guan)管(guan)涵(han)(han)的另一端與涵(han)(han)洞(dong)之間(jian)的間(jian)距應使用(yong)(yong)沙袋或漿砌片石封(feng)堵，寬度(du)為50cm，然后(hou)(hou)可以開始回(hui)填。兩(liang)(liang)側可用(yong)(yong)粗(cu)砂(sha)水(shui)密法壓(ya)實或用(yong)(yong)混凝土(tu)振(zhen)搗器(qi)澆筑。頂部(bu)(bu)采(cai)(cai)用(yong)(yong)高壓(ya)泵輸送膨脹(zhang)水(shui)泥砂(sha)漿。該段管(guan)道周(zhou)圍(wei)(wei)填充完成(cheng)后(hou)(hou)，并(bing)連接兩(liang)(liang)根管(guan)道。連接完成(cheng)后(hou)(hou)，按上(shang)述方(fang)法回(hui)填，并(bing)按此(ci)順序完成(cheng)波(bo)(bo)(bo)紋鋼(gang)管(guan)的施(shi)工
