大直徑鋼波紋管拼裝方法你知道嗎?

1、搭(da)設拼(pin)裝(zhuang)支架(jia):搭(da)設腳(jiao)(jiao)(jiao)(jiao)手(shou)架(jia)根(gen)據(ju)波(bo)紋管(guan)(guan)的直徑(jing)提前確定,采用管(guan)(guan)扣連接鋼管(guan)(guan)的方式(shi)搭(da)設腳(jiao)(jiao)(jiao)(jiao)手(shou)架(jia),形式(shi)分A型和B型腳(jiao)(jiao)(jiao)(jiao)手(shou)架(jia)長度一般長25m、克0、6m、高為2d3(d為波(bo)紋管(guan)(guan)直徑(jing)),B型腳(jiao)(jiao)(jiao)(jiao)手(shou)架(jia)一般克為25m高依據(ju)波(bo)紋管(guan)(guan)直徑(jing)大小拼(pin)裝(zhuang)接縫位置(zhi)確定尺寸。腳(jiao)(jiao)(jiao)(jiao)手(shou)架(jia)按上述尺寸搭(da)設便(bian)于施工、

2、拼(pin)裝(zhuang)類型與搭(da)接方式:拼(pin)裝(zhuang)以中心軸線為基準,由中心向兩端對稱進(jin)行安裝(zhuang),直至兩端。1斷(duan)(duan)面(mian)(奇數斷(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)面(mian)(偶數斷(duan)(duan)面(mian))、加(jia)強斷(duan)(duan)面(mian)(偶數斷(duan)(duan)管管片)

3、波(bo)紋管(guan)拼裝(zhuang):采用刻槽(cao)法施工的地基(ji),安(an)(an)裝(zhuang)吊車(che)依據(ju)刻槽(cao)深(shen)度,依次(ci)安(an)(an)裝(zhuang)底部(bu)管(guan)片(pian)。底部(bu)管(guan)片(pian)安(an)(an)裝(zhuang)完成后對(dui)剩余管(guan)片(pian)進行(xing)安(an)(an)裝(zhuang)。管(guan)片(pian)安(an)(an)裝(zhuang)同平基(ji)上(shang)的鋼(gang)波(bo)紋管(guan)施工。

首圈(quan)(quan)波紋(wen)(wen)管(guan)(guan)圈(quan)(quan)為(wei)奇數斷面,拼裝(zhuang)(zhuang)(zhuang)時應將(jiang)(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)(yu)地(di)上安(an)裝(zhuang)(zhuang)(zhuang),使用(yong)(yong)(yong)(yong)鐵鉤的(de)(de)(de)一端勾住I斷面片(pian)(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian)(pian))波紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)螺絲囗,用(yong)(yong)(yong)(yong)12噸的(de)(de)(de)吊車勾住鐵鉤的(de)(de)(de)另一端,將(jiang)(jiang)波紋(wen)(wen)管(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)(yu)墊層(ceng)上,然后(hou)(hou)使用(yong)(yong)(yong)(yong)同樣的(de)(de)(de)辦法將(jiang)(jiang)第(di)二(er)片(pian)(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian)(pian))波紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)按圖3、21斷面所示的(de)(de)(de)搭接(jie)方式放置(zhi),使用(yong)(yong)(yong)(yong)撬棍將(jiang)(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)螺栓(shuan)口對齊(qi),將(jiang)(jiang)提前準備好的(de)(de)(de)螺栓(shuan)螺紋(wen)(wen)部(bu)涂上渢滑劑,由(you)內冋外(wai)插入(ru)孔位;波紋(wen)(wen)管(guan)(guan)外(wai)側套上凹(ao)墊圈(quan)(quan)或凸(tu)墊圈(quan)(quan),遇波使用(yong)(yong)(yong)(yong)凸(tu)墊圈(quan)(quan),遇波峰(feng)使用(yong)(yong)(yong)(yong)凹(ao)墊圈(quan)(quan)墊圈(quan)(quan)外(wai)側旋(xuan)上螺母,在用(yong)(yong)(yong)(yong)套筒扳手(shou)預緊(jin)螺母,然后(hou)(hou)使用(yong)(yong)(yong)(yong)電動扳手(shou)緊(jin)固螺母兩塊板片(pian)(pian)(pian)(pian)洤全部(bu)安(an)裝(zhuang)(zhuang)(zhuang)完畢(bi)(bi);波紋(wen)(wen)管(guan)(guan)的(de)(de)(de)螺栓(shuan)安(an)裝(zhuang)(zhuang)(zhuang)完畢(bi)(bi)后(hou)(hou),需采用(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)注膠(jiao)槍于(yu)(yu)端部(bu)接(jie)合處、緊(jin)回件連接(jie)的(de)(de)(de)螺栓(shuan)孔空隙(xi)處涂抹中性硅酮耐候膠(jiao)。緊(jin)接(jie)著(zhu)按2#管(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)施工拼裝(zhuang)(zhuang)(zhuang)順序(xu),拼裝(zhuang)(zhuang)(zhuang)好首圈(quan)(quan)波紋(wen)(wen)管(guan)(guan)圖36偶數、奇數斷面交替拼裝(zhuang)(zhuang)(zhuang)順序(xu)

4、加強斷面拼裝

當波紋管(guan)涵直徑較(jiao)大、填(tian)土高(gao)度較(jiao)高(gao)時,必須設置加(jia)強管(guan)片,稱為加(jia)強圈”,加(jia)強斷面(mian)的管(guan)片安(an)裝工序。
