【收藏】鋼波紋管(guan)安裝方法
1、涵(han)洞施工前,準備好相關材料、人(ren)員和設備進場(chang),做好施工過程中(zhong)的安全防護(hu),并(bing)用(yong)圍欄保護(hu)路(lu)基邊坡(po),使石塊等物體滑下傷人(ren)
2基礎處理:回填砂礫或片(pian)石混(hun)凝土,平整基層,可更換厚度為(wei)30-50cm的(de)砂礫石材料,流水縱(zong)坡(po)宜在3%左右,并可確定每個(ge)涵洞的(de)中(zhong)線(xian)(xian)和邊線(xian)(xian)
3。在鋼(gang)波(bo)(bo)紋管(guan)(guan)(guan)的施工過程中,采(cai)用分段施工的方法(fa)。在原拱涵(han)基(ji)礎(chu)上(shang)提前并排布置兩根角鋼(gang),長度根據涵(han)洞長度確定,可作為涵(han)管(guan)(guan)(guan)推壓時的滑軌。鋼(gang)波(bo)(bo)紋管(guan)(guan)(guan)的管(guan)(guan)(guan)徑(jing)(jing)管(guan)(guan)(guan)涵(han)可根據項(xiang)目需要有不同的規(gui)格。組裝(zhuang)(zhuang)管(guan)(guan)(guan)道直(zhi)徑(jing)(jing)為0.5m-2.5m,每段長度為3.06M。采(cai)用內(外)法(fa)蘭螺栓(shuan)連接(jie),組裝(zhuang)(zhuang)管(guan)(guan)(guan)道直(zhi)徑(jing)(jing)3m-8m,板間(jian)搭接(jie)螺栓(shuan)緊固。
4如果涵(han)(han)(han)洞長(chang)度(du)(du)小(xiao)于(yu)30m,鋼波(bo)紋管(guan)(guan)(guan)(guan)涵(han)(han)(han)兩側與原涵(han)(han)(han)洞之間的寬度(du)(du)大(da)于(yu)80cm,可(ke)將整個鋼波(bo)紋管(guan)(guan)(guan)(guan)涵(han)(han)(han)推至下游(you)或上(shang)游(you)一(yi)端(duan)(duan)。就位后(hou)(hou)(hou),可(ke)進行一(yi)端(duan)(duan)擋(dang)土墻(qiang)的砌(qi)(qi)(qi)筑。周圍(wei)回(hui)填(tian)(tian)可(ke)采(cai)用礫石(shi)(shi)(shi)、碎石(shi)(shi)(shi)土、漿砌(qi)(qi)(qi)片石(shi)(shi)(shi)等(deng)進行回(hui)填(tian)(tian)。涵(han)(han)(han)洞長(chang)度(du)(du)大(da)于(yu)30m,鋼波(bo)紋管(guan)(guan)(guan)(guan)涵(han)(han)(han)兩側寬度(du)(du)小(xiao)于(yu)80cm時,頂(ding)部應采(cai)用漿砌(qi)(qi)(qi)片石(shi)(shi)(shi)或高壓(ya)泵送膨脹水(shui)泥砂(sha)(sha)(sha)漿,3m-6m長(chang)的涵(han)(han)(han)管(guan)(guan)(guan)(guan)可(ke)推至下游(you)或上(shang)游(you)的一(yi)端(duan)(duan)。就位后(hou)(hou)(hou)即可(ke)進行固定,并可(ke)修建頂(ding)部毛石(shi)(shi)(shi)端(duan)(duan)墻(qiang)。鋼波(bo)紋管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)涵(han)(han)(han)的另一(yi)端(duan)(duan)與涵(han)(han)(han)洞之間的間距應使用沙袋(dai)或漿砌(qi)(qi)(qi)片石(shi)(shi)(shi)封堵,寬度(du)(du)為50cm,然后(hou)(hou)(hou)可(ke)以開始(shi)回(hui)填(tian)(tian)。兩側可(ke)用粗砂(sha)(sha)(sha)水(shui)密(mi)法(fa)(fa)壓(ya)實(shi)或用混凝土振搗器澆筑。頂(ding)部采(cai)用高壓(ya)泵輸送膨脹水(shui)泥砂(sha)(sha)(sha)漿。該(gai)段管(guan)(guan)(guan)(guan)道周圍(wei)填(tian)(tian)充完(wan)(wan)成后(hou)(hou)(hou),并連(lian)接(jie)兩根管(guan)(guan)(guan)(guan)道。連(lian)接(jie)完(wan)(wan)成后(hou)(hou)(hou),按上(shang)述(shu)方法(fa)(fa)回(hui)填(tian)(tian),并按此順序完(wan)(wan)成波(bo)紋鋼管(guan)(guan)(guan)(guan)的施工
