【收藏】鋼波紋管安裝方法
1、涵洞施工(gong)前(qian),準(zhun)備好(hao)(hao)相關材(cai)料(liao)、人員(yuan)和設備進場,做好(hao)(hao)施工(gong)過程(cheng)中的安全(quan)防護,并(bing)用(yong)圍欄保(bao)護路基(ji)邊坡,使石塊等物體滑下(xia)傷人
2基(ji)(ji)礎處理(li):回(hui)填砂礫(li)或片(pian)石(shi)混凝土(tu),平整基(ji)(ji)層,可更換厚度為(wei)30-50cm的砂礫(li)石(shi)材(cai)料(liao),流水縱(zong)坡宜在(zai)3%左(zuo)右,并可確(que)定(ding)每個涵洞的中(zhong)線和邊線
3。在鋼(gang)波紋管(guan)(guan)的施工(gong)過(guo)程中,采(cai)用分段施工(gong)的方法。在原拱涵(han)(han)(han)基礎上提前(qian)并(bing)排布置兩根(gen)角鋼(gang),長(chang)度(du)根(gen)據涵(han)(han)(han)洞長(chang)度(du)確定,可作為涵(han)(han)(han)管(guan)(guan)推壓(ya)時的滑(hua)軌。鋼(gang)波紋管(guan)(guan)的管(guan)(guan)徑管(guan)(guan)涵(han)(han)(han)可根(gen)據項目需要有不(bu)同的規格。組裝(zhuang)管(guan)(guan)道(dao)直(zhi)(zhi)徑為0.5m-2.5m,每段長(chang)度(du)為3.06M。采(cai)用內(nei)(外)法蘭(lan)螺栓連(lian)接,組裝(zhuang)管(guan)(guan)道(dao)直(zhi)(zhi)徑3m-8m,板間搭接螺栓緊固(gu)。
4如果涵(han)(han)(han)洞(dong)(dong)長度(du)小于(yu)30m,鋼(gang)波紋(wen)(wen)管(guan)涵(han)(han)(han)兩(liang)側與原涵(han)(han)(han)洞(dong)(dong)之間(jian)的(de)(de)(de)寬(kuan)(kuan)度(du)大(da)于(yu)80cm,可(ke)(ke)將整個(ge)鋼(gang)波紋(wen)(wen)管(guan)涵(han)(han)(han)推至下游(you)或(huo)(huo)(huo)(huo)上(shang)游(you)一端(duan)。就位后(hou)(hou),可(ke)(ke)進(jin)(jin)行(xing)一端(duan)擋土墻(qiang)的(de)(de)(de)砌筑。周圍(wei)回(hui)填可(ke)(ke)采用(yong)礫(li)石(shi)、碎石(shi)土、漿砌片石(shi)等進(jin)(jin)行(xing)回(hui)填。涵(han)(han)(han)洞(dong)(dong)長度(du)大(da)于(yu)30m,鋼(gang)波紋(wen)(wen)管(guan)涵(han)(han)(han)兩(liang)側寬(kuan)(kuan)度(du)小于(yu)80cm時,頂部(bu)應采用(yong)漿砌片石(shi)或(huo)(huo)(huo)(huo)高(gao)壓泵送(song)膨脹(zhang)水泥砂(sha)漿,3m-6m長的(de)(de)(de)涵(han)(han)(han)管(guan)可(ke)(ke)推至下游(you)或(huo)(huo)(huo)(huo)上(shang)游(you)的(de)(de)(de)一端(duan)。就位后(hou)(hou)即可(ke)(ke)進(jin)(jin)行(xing)固定,并(bing)可(ke)(ke)修建頂部(bu)毛石(shi)端(duan)墻(qiang)。鋼(gang)波紋(wen)(wen)管(guan)管(guan)涵(han)(han)(han)的(de)(de)(de)另一端(duan)與涵(han)(han)(han)洞(dong)(dong)之間(jian)的(de)(de)(de)間(jian)距應使(shi)用(yong)沙(sha)袋或(huo)(huo)(huo)(huo)漿砌片石(shi)封堵,寬(kuan)(kuan)度(du)為50cm,然后(hou)(hou)可(ke)(ke)以開始回(hui)填。兩(liang)側可(ke)(ke)用(yong)粗砂(sha)水密法壓實或(huo)(huo)(huo)(huo)用(yong)混(hun)凝土振(zhen)搗器澆(jiao)筑。頂部(bu)采用(yong)高(gao)壓泵輸(shu)送(song)膨脹(zhang)水泥砂(sha)漿。該段(duan)管(guan)道(dao)周圍(wei)填充(chong)完成后(hou)(hou),并(bing)連接兩(liang)根管(guan)道(dao)。連接完成后(hou)(hou),按上(shang)述方法回(hui)填,并(bing)按此順序完成波紋(wen)(wen)鋼(gang)管(guan)的(de)(de)(de)施工
