全體管(guan)(guan)(guan)聯接(jie)(jie)法(fa)蘭選(xuan)用(yong)(yong)角鋼(gang)、鋼(gang)板(ban)制造,波紋板(ban)焊接(jie)(jie)選(xuan)用(yong)(yong)對焊接(jie)(jie)頭。緊固(gu)件(jian)選(xuan)用(yong)(yong)中的規(gui)范緊固(gu)件(jian),其強度和規(gui)范應滿意力學懇求(qiu),且不低于(yu)(yu)管(guan)(guan)(guan)材強度懇求(qiu)。墊片與緊固(gu)件(jian)相配(pei)。螺栓與螺母均選(xuan)用(yong)(yong)熱浸鍍鋅處(chu)理(li)。管(guan)(guan)(guan)壁及配(pei)套附件(jian)均經過熱浸鍍鋅處(chu)理(li),其鍍鋅層的均勻厚度大于(yu)(yu)84um。
涵(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)運到施工(gong)(gong)現場后(hou),工(gong)(gong)地現場涂(tu)刷兩(liang)頭(tou)瀝青。鋼(gang)波紋(wen)涵(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)施工(gong)(gong)時,選(xuan)用(yong)分段施工(gong)(gong)的(de)辦法,預先在原拱(gong)涵(han)基底用(yong)角鋼(gang)并排兩(liang)根,長(chang)度(du)依據(ju)(ju)涵(han)長(chang)確認(ren),作涵(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)推動時的(de)滑(hua)軌,鋼(gang)波紋(wen)涵(han)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)徑依據(ju)(ju)工(gong)(gong)程需求(qiu)可有不同的(de)規(gui)格(ge),整裝管(guan)(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)徑為0.5m-2.5m,每節長(chang)度(du)3.06米,選(xuan)用(yong)內(外)法蘭螺栓(shuan)聯接,組裝管(guan)(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)徑為3m-8m,板與板搭接高強螺栓(shuan)緊固。

假如涵(han)長小于30米,鋼波紋(wen)涵(han)管兩(liang)側與原涵(han)寬度大于80cm,可將(jiang)整道鋼波紋(wen)涵(han)管在下游(you)或(huo)上游(you)向一端(duan)推動,就位以后,再(zai)進行(xing)一端(duan)擋墻(qiang)的砌筑,四周的回(hui)填作業,可回(hui)填沙礫(li)、碎石土、砌筑片(pian)石等。頂部選(xuan)用砌片(pian)石或(huo)高壓(ya)泵送(song)脹大水(shui)泥砂漿。
鋼(gang)(gang)波(bo)紋(wen)(wen)涵管(guan)是(shi)選(xuan)用套筒或法(fa)蘭方法(fa)聯(lian)接,并且能(neng)夠依據需求定制長度,即(ji)便對錯熟(shu)練(lian)工也能(neng)夠操作(zuo),施(shi)工以少量的手工操作(zuo),可在短時刻內(nei)完結,既方便又方便。鋼(gang)(gang)波(bo)紋(wen)(wen)涵管(guan)是(shi)選(xuan)用鋼(gang)(gang)管(guan)熱浸(jin)鍍鋅,所以運用壽數長,壽數為80-100年。
在腐蝕性特別大的環境下運用時,選用表里表面瀝清附層的鋼波紋涵管,可在原運用壽數根底上提高約20年以上。鋼帶波紋管表面進行特殊預處理,以加強鋼材的防腐蝕能力以及鋼材和塑料的粘合力,在塑料原料充分熔融的狀態下纏繞成型,管材的全體結構結實牢靠。//hanihanbj.com/
