鋼波紋管從資料(liao)與結構和(he)功(gong)用的實(shi)質(zhi)關系上分析,選用柔(rou)性高(gao)強度的鋼波紋(wen)管(guan)洞(dong)由于軸向(xiang)波紋(wen)的存(cun)在,使(shi)其具有受力(li)特(te)征,軸向(xiang)和(he)徑(jing)向(xiang)一(yi)起散布因荷載(zai)引(yin)起的應(ying)力(li)應(ying)變,可(ke)以更大程度上渙散荷載(zai)的應(ying)力(li)會(hui)合(he),更好地發揮鋼結構的優勢。

鋼(gang)波紋(wen)管(guan)(guan)的資(zi)料普通(tong)為青(qing)銅、黃銅、不(bu)銹(xiu)鋼(gang)、蒙乃(nai)爾(er)合金(jin)和因康鎳(nie)爾(er)合金(jin)等。鋼(gang)波紋(wen)管(guan)(guan)選用(yong)規范化設(she)計(ji)方(fang)案,出(chu)產(chan)(chan)制(zhi)造(zao),設(she)計(ji)方(fang)案簡易,出(chu)產(chan)(chan)制(zhi)造(zao)周期時間短;工(gong)(gong)(gong)(gong)程(cheng)(cheng)項目具體工(gong)(gong)(gong)(gong)程(cheng)(cheng)造(zao)價比相似(si)跨距(ju)的橋(qiao),洞低;工(gong)(gong)(gong)(gong)程(cheng)(cheng)施工(gong)(gong)(gong)(gong)短工(gong)(gong)(gong)(gong)期,要(yao)害為組裝工(gong)(gong)(gong)(gong)程(cheng)(cheng)施工(gong)(gong)(gong)(gong);金(jin)屬(shu)資(zi)料波紋(wen)管(guan)(guan)代替(ti)混凝土結構(gou)展(zhan)開洞工(gong)(gong)(gong)(gong)程(cheng)(cheng)施工(gong)(gong)(gong)(gong)。
銜接(jie)裝置鋼波紋管(guan)(guan):依(yi)據涵(han)洞實際情況,排放涵(han)管(guan)(guan)。如果(guo)涵(han)洞兩邊(bian)(bian)進出水口(kou)(kou)是與路基(ji)同斜度的(de)斜口(kou)(kou)形式,裝置時先(xian)裝置中(zhong)心管(guan)(guan)節,在根(gen)底長度方向留出進出水口(kou)(kou)的(de)位置。中(zhong)心管(guan)(guan)節全(quan)部裝置完(wan)畢(bi),校正(zheng)就位后再裝置兩邊(bian)(bian)進出水口(kou)(kou)。

裝(zhuang)置(zhi)時(shi)從一側排放(fang)根管(guan)(guan)(guan)節,使(shi)(shi)其管(guan)(guan)(guan)子中心(xin)和根底縱向(xiang)中心(xin)線(xian)平行,同(tong)樣把二根管(guan)(guan)(guan)放(fang)置(zhi)就位(wei),當兩根管(guan)(guan)(guan)相鄰法(fa)(fa)蘭間(jian)相距3—5cm的(de)縫隙時(shi),用小撬棍對準法(fa)(fa)蘭上的(de)螺(luo)栓(shuan)孔,使(shi)(shi)其兩根管(guan)(guan)(guan)法(fa)(fa)蘭上的(de)螺(luo)栓(shuan)孔對正,這時(shi)從二節管(guan)(guan)(guan)的(de)另一端(duan)用撬杠撬動(dong)管(guan)(guan)(guan)節,使(shi)(shi)其縱向(xiang)平移,使(shi)(shi)兩法(fa)(fa)蘭間(jian)距在2cm左(zuo)右,然(ran)后全部穿上螺(luo)栓(shuan),擰(ning)上螺(luo)絲,帶平扣即可。
爾后依此方(fang)法逐(zhu)節(jie)依次銜(xian)(xian)接,每道涵洞中心管節(jie)無先(xian)后,可以隨(sui)意銜(xian)(xian)接。由裂(lie)(lie)紋和斷(duan)口(kou)形貌(mao)的分析(xi)可知:波(bo)紋管裂(lie)(lie)紋的發生是(shi)晶(jing)間腐(fu)蝕和應力腐(fu)蝕聯合效(xiao)果的成果,且先(xian)發生晶(jing)間腐(fu)蝕;波(bo)紋管斷(duan)口(kou)主要為沿(yan)晶(jing)開(kai)裂(lie)(lie)特征,斷(duan)口(kou)腐(fu)蝕產(chan)物中硫元素含量較高(gao)。
在石化職業中,連多硫酸環境容易引起設備發生應力腐蝕裂紋,連多硫酸一般是加工含硫原油的裝置在罷工期間,殘留在設備中的含硫腐蝕產物與水和氧反應生成的。具有較大的抗變形和抗沉降才干,施工過程中重量輕、設備便利快捷、施工簡潔等許多長處。//hanihanbj.com/
