大直徑鋼波紋管拼裝方法你知道嗎?
1、搭設拼裝支架(jia):搭設腳(jiao)手(shou)架(jia)根據波(bo)紋(wen)管的直徑(jing)提前(qian)確定,采(cai)用管扣連接鋼(gang)管的方式(shi)搭設腳(jiao)手(shou)架(jia),形式(shi)分A型和B型腳(jiao)手(shou)架(jia)長度一(yi)般長25m、克0、6m、高(gao)(gao)為2d3(d為波(bo)紋(wen)管直徑(jing)),B型腳(jiao)手(shou)架(jia)一(yi)般克為25m高(gao)(gao)依(yi)據波(bo)紋(wen)管直徑(jing)大小拼裝接縫(feng)位置確定尺寸。腳(jiao)手(shou)架(jia)按上述尺寸搭設便于施(shi)工、
2、拼裝(zhuang)類(lei)型與搭(da)接方式:拼裝(zhuang)以中心(xin)軸線為基準,由中心(xin)向兩端對(dui)稱進行安裝(zhuang),直(zhi)至兩端。1斷面(奇數(shu)斷面)、Ⅱ斷面(偶數(shu)斷面)、加強(qiang)斷面(偶數(shu)斷管管片)
3、波紋(wen)管(guan)(guan)(guan)拼裝(zhuang)(zhuang):采用刻槽法(fa)施工的(de)地基,安裝(zhuang)(zhuang)吊(diao)車依(yi)據刻槽深(shen)度,依(yi)次(ci)安裝(zhuang)(zhuang)底部管(guan)(guan)(guan)片。底部管(guan)(guan)(guan)片安裝(zhuang)(zhuang)完(wan)成后對剩余管(guan)(guan)(guan)片進行安裝(zhuang)(zhuang)。管(guan)(guan)(guan)片安裝(zhuang)(zhuang)同平基上的(de)鋼波紋(wen)管(guan)(guan)(guan)施工。
首圈(quan)(quan)波紋(wen)(wen)管(guan)(guan)圈(quan)(quan)為奇數(shu)斷(duan)面(mian)(mian),拼裝(zhuang)(zhuang)時應將管(guan)(guan)片立于(yu)地(di)上(shang)安(an)裝(zhuang)(zhuang),使(shi)用(yong)(yong)鐵鉤的(de)(de)(de)(de)一端勾住I斷(duan)面(mian)(mian)片(1#管(guan)(guan)片)波紋(wen)(wen)管(guan)(guan)管(guan)(guan)片螺(luo)(luo)(luo)絲囗(wei),用(yong)(yong)12噸的(de)(de)(de)(de)吊車勾住鐵鉤的(de)(de)(de)(de)另一端,將波紋(wen)(wen)管(guan)(guan)片立于(yu)墊層上(shang),然后(hou)使(shi)用(yong)(yong)同樣的(de)(de)(de)(de)辦法將第二片(6#管(guan)(guan)片)波紋(wen)(wen)管(guan)(guan)管(guan)(guan)片按圖3、21斷(duan)面(mian)(mian)所示的(de)(de)(de)(de)搭接方式放置,使(shi)用(yong)(yong)撬棍將管(guan)(guan)片的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)(shuan)口對齊(qi),將提前準(zhun)備好的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)(shuan)螺(luo)(luo)(luo)紋(wen)(wen)部(bu)(bu)涂上(shang)渢滑(hua)劑,由(you)內(nei)冋外插入孔(kong)位;波紋(wen)(wen)管(guan)(guan)外側(ce)(ce)套上(shang)凹(ao)(ao)墊圈(quan)(quan)或(huo)凸(tu)(tu)墊圈(quan)(quan),遇(yu)波使(shi)用(yong)(yong)凸(tu)(tu)墊圈(quan)(quan),遇(yu)波峰使(shi)用(yong)(yong)凹(ao)(ao)墊圈(quan)(quan)墊圈(quan)(quan)外側(ce)(ce)旋(xuan)上(shang)螺(luo)(luo)(luo)母,在用(yong)(yong)套筒(tong)扳(ban)手預緊螺(luo)(luo)(luo)母,然后(hou)使(shi)用(yong)(yong)電動扳(ban)手緊固螺(luo)(luo)(luo)母兩塊板片洤全(quan)部(bu)(bu)安(an)裝(zhuang)(zhuang)完(wan)畢;波紋(wen)(wen)管(guan)(guan)的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)(shuan)安(an)裝(zhuang)(zhuang)完(wan)畢后(hou),需(xu)采用(yong)(yong)專(zhuan)用(yong)(yong)注膠槍于(yu)端部(bu)(bu)接合(he)處、緊回件(jian)連接的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)(shuan)孔(kong)空隙處涂抹中性硅酮耐候(hou)膠。緊接著(zhu)按2#管(guan)(guan)片、5#管(guan)(guan)片、3#管(guan)(guan)片、4#管(guan)(guan)片的(de)(de)(de)(de)施工拼裝(zhuang)(zhuang)順(shun)序,拼裝(zhuang)(zhuang)好首圈(quan)(quan)波紋(wen)(wen)管(guan)(guan)圖36偶數(shu)、奇數(shu)斷(duan)面(mian)(mian)交替拼裝(zhuang)(zhuang)順(shun)序
4、加強斷面拼裝
當波(bo)紋管涵直徑較大、填土高度較高時,必須設置加強管片(pian),稱為加強圈”,加強斷面(mian)的管片(pian)安裝工(gong)序。
