只選對的!不同使用場景如何選擇適合的鋼波紋管?
代替小(xiao)橋采用(yong)(yong)波紋管(guan)(guan)多孔使用(yong)(yong)。兩(liang)條道(dao)(dao)路立體(ti)十(shi)字相交時,可(ke)采用(yong)(yong)鋼波紋板通(tong)道(dao)(dao)。橫穿道(dao)(dao)路或鐵路的(de)涵洞排(pai)水用(yong)(yong)暗渠、行人(ren)車輛通(tong)道(dao)(dao)、滲水井;各(ge)式(shi)各(ge)種土建(jian)工程的(de)排(pai)水管(guan)(guan)、滲水井;排(pai)水用(yong)(yong)一住宅(zhai)小(xiao)區等土地開發時用(yong)(yong)的(de)排(pai)水管(guan)(guan),高爾夫球場,管(guan)(guan)道(dao)(dao),
傍山險路無便道時,使(shi)用波(bo)(bo)紋(wen)管(guan)可分幅施工(gong)(gong),保(bao)證提前通(tong)車時間。淺填土時,可應(ying)(ying)用波(bo)(bo)紋(wen)管(guan)涵施工(gong)(gong)。因為填土淺,水泥圓(yuan)管(guan)涵在施工(gong)(gong)過程中輕易(yi)泛起裂痕,波(bo)(bo)紋(wen)管(guan)是一種柔性結構,能適應(ying)(ying)變形和(he)重載車輛(liang)通(tong)行的要(yao)求。
舊涵(han)(han)(han)快修工(gong)(gong)程因(yin)為有些地區(qu)不平均(jun)沉降(jiang)對涵(han)(han)(han)洞產生不同程度的(de)破壞,如石(shi)拱(gong)涵(han)(han)(han),在高(gao)填方地段挖出重新修復工(gong)(gong)期(qi)長,斷交或者修便道均(jun)增加用(yong)度,內套水泥圓(yuan)管(guan)(guan)不好施(shi)工(gong)(gong),圓(yuan)管(guan)(guan)涵(han)(han)(han)與(yu)舊拱(gong)涵(han)(han)(han)中間填充水泥砂漿難題。采用(yong)波紋涵(han)(han)(han)管(guan)(guan)可在涵(han)(han)(han)洞外連(lian)接好后推進,連(lian)接處無縫隙;在管(guan)(guan)側開孔,以便填充片石(shi)和(he)噴筑砂漿增加管(guan)(guan)涵(han)(han)(han)和(he)原涵(han)(han)(han)洞的(de)整體(ti)性;另(ling)外波紋涵(han)(han)(han)管(guan)(guan)管(guan)(guan)體(ti)輕,便于施(shi)工(gong)(gong);在施(shi)工(gong)(gong)中邊(bian)推進邊(bian)清(qing)理地基,保證(zheng)施(shi)工(gong)(gong)職員的(de)安全(quan)。
有些(xie)地(di)區陣(zhen)發性暴雨(yu)比較(jiao)多,對(dui)橋涵(han)(han)構造(zao)物輕(qing)易造(zao)成(cheng)破壞,而(er)混凝土構造(zao)物沖垮后(hou)不能被再(zai)次(ci)利(li)(li)用,必需修建新的涵(han)(han)洞,造(zao)成(cheng)斷交,重新修建,增加了施工用度,施工時間長,而(er)波紋管水毀(hui)后(hou)可(ke)重復利(li)(li)用。
在(zai)地基(ji)承載(zai)力較低的情況下無(wu)須對地基(ji)特殊處理,只要換填一定(ding)厚度的沙(sha)礫片石墊層。
在煤(mei)礦(kuang)采空(kong)區(qu)修建的公路,因為地(di)下(xia)采空(kong)可造(zao)成地(di)面(mian)不同(tong)程度(du)的下(xia)降(jiang)(jiang),產生不平均沉降(jiang)(jiang),對一(yi)般水泥構造(zao)物產生不同(tong)程度(du)的破壞(huai),鋼(gang)(gang)波紋管涵是一(yi)種柔性結(jie)構,波紋管在結(jie)構上具有橫向補償位移的優良特性,可充分施展鋼(gang)(gang)材抗拉機能強,變形(xing)機能優勝的特點,具有較大的抗變形(xing)和抗沉降(jiang)(jiang)能力(li),特別適合(he)于(yu)軟土(tu),膨脹土(tu)地(di),濕陷性黃土(tu)地(di)基承載力(li)較低地(di)區(qu)和地(di)震多發地(di)區(qu)。
鋼波紋管合用(yong)(yong)的(de)場(chang)景地形:山嶺重(zhong)丘區(qu)沖(chong)溝采用(yong)(yong)波(bo)紋(wen)管(guan)可替換橋涵,施(shi)工(gong)速度快,節(jie)省(sheng)造價。山區(qu)高填(tian)土時可使(shi)用(yong)(yong)波(bo)紋(wen)管(guan)施(shi)工(gong)。在高填(tian)方公路施(shi)工(gong)中,因為建材運(yun)輸(shu),現場(chang)往溝底的(de)倒卸等難(nan)題(ti)(ti)以(yi)及無(wu)法修建臨時便道可利用(yong)(yong)波(bo)紋(wen)涵管(guan)半幅(fu)施(shi)工(gong)`安裝速度快`施(shi)工(gong)工(gong)期短等特點,同時也可避免因為回填(tian)造成的(de)不平均沉(chen)降等題(ti)(ti)目(mu)。
跟著社會發展,鋼波(bo)紋(wen)涵管(guan)耐(nai)用(yong),輕便,環保等特性越來越顯(xian)著,鋼波(bo)紋(wen)涵管(guan)的應用(yong)范圍也原來越廣。目前在很多工程(cheng)項(xiang)目中都有鋼波(bo)紋(wen)涵管(guan)的身影。
