大直徑鋼波紋管拼裝方法你知道嗎?
1、搭(da)設(she)拼裝支架:搭(da)設(she)腳手(shou)架根(gen)據(ju)波(bo)紋(wen)(wen)管的(de)直(zhi)徑提前確定,采用管扣連(lian)接(jie)鋼管的(de)方式搭(da)設(she)腳手(shou)架,形式分A型和B型腳手(shou)架長度一般長25m、克0、6m、高(gao)為2d3(d為波(bo)紋(wen)(wen)管直(zhi)徑),B型腳手(shou)架一般克為25m高(gao)依據(ju)波(bo)紋(wen)(wen)管直(zhi)徑大小拼裝接(jie)縫位置確定尺寸。腳手(shou)架按上述(shu)尺寸搭(da)設(she)便(bian)于施(shi)工、
2、拼裝(zhuang)類型與搭接(jie)方式(shi):拼裝(zhuang)以中(zhong)心軸線(xian)為基準,由(you)中(zhong)心向兩端對稱進(jin)行安裝(zhuang),直至兩端。1斷(duan)面(mian)(奇數(shu)斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶(ou)(ou)數(shu)斷(duan)面(mian))、加強斷(duan)面(mian)(偶(ou)(ou)數(shu)斷(duan)管(guan)管(guan)片(pian))
3、波紋管拼裝(zhuang)(zhuang)(zhuang):采用(yong)刻槽法施工的地基(ji),安(an)裝(zhuang)(zhuang)(zhuang)吊(diao)車依據刻槽深(shen)度,依次安(an)裝(zhuang)(zhuang)(zhuang)底部管片(pian)(pian)。底部管片(pian)(pian)安(an)裝(zhuang)(zhuang)(zhuang)完成后(hou)對剩余管片(pian)(pian)進行安(an)裝(zhuang)(zhuang)(zhuang)。管片(pian)(pian)安(an)裝(zhuang)(zhuang)(zhuang)同(tong)平基(ji)上的鋼(gang)波紋管施工。
首圈(quan)波(bo)紋(wen)管(guan)(guan)圈(quan)為奇(qi)(qi)數(shu)斷(duan)面(mian),拼(pin)裝(zhuang)時應將(jiang)管(guan)(guan)片(pian)立(li)于(yu)地上(shang)(shang)安(an)裝(zhuang),使(shi)(shi)用鐵鉤的(de)一端勾(gou)住I斷(duan)面(mian)片(pian)(1#管(guan)(guan)片(pian))波(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)螺(luo)絲囗,用12噸的(de)吊車勾(gou)住鐵鉤的(de)另一端,將(jiang)波(bo)紋(wen)管(guan)(guan)片(pian)立(li)于(yu)墊(dian)(dian)層(ceng)上(shang)(shang),然后(hou)使(shi)(shi)用同樣的(de)辦法將(jiang)第二片(pian)(6#管(guan)(guan)片(pian))波(bo)紋(wen)管(guan)(guan)管(guan)(guan)片(pian)按(an)圖3、21斷(duan)面(mian)所示的(de)搭(da)接(jie)方式放置,使(shi)(shi)用撬棍(gun)將(jiang)管(guan)(guan)片(pian)的(de)螺(luo)栓(shuan)口對(dui)齊,將(jiang)提前(qian)準備(bei)好的(de)螺(luo)栓(shuan)螺(luo)紋(wen)部涂(tu)(tu)上(shang)(shang)渢滑劑,由內冋外插(cha)入(ru)孔(kong)位(wei);波(bo)紋(wen)管(guan)(guan)外側(ce)套上(shang)(shang)凹(ao)墊(dian)(dian)圈(quan)或凸墊(dian)(dian)圈(quan),遇波(bo)使(shi)(shi)用凸墊(dian)(dian)圈(quan),遇波(bo)峰(feng)使(shi)(shi)用凹(ao)墊(dian)(dian)圈(quan)墊(dian)(dian)圈(quan)外側(ce)旋上(shang)(shang)螺(luo)母,在用套筒(tong)扳(ban)手預緊(jin)螺(luo)母,然后(hou)使(shi)(shi)用電動扳(ban)手緊(jin)固螺(luo)母兩塊板片(pian)洤(quan)全部安(an)裝(zhuang)完畢;波(bo)紋(wen)管(guan)(guan)的(de)螺(luo)栓(shuan)安(an)裝(zhuang)完畢后(hou),需采(cai)用專用注膠槍于(yu)端部接(jie)合處、緊(jin)回(hui)件(jian)連接(jie)的(de)螺(luo)栓(shuan)孔(kong)空隙處涂(tu)(tu)抹中性硅酮(tong)耐候膠。緊(jin)接(jie)著(zhu)按(an)2#管(guan)(guan)片(pian)、5#管(guan)(guan)片(pian)、3#管(guan)(guan)片(pian)、4#管(guan)(guan)片(pian)的(de)施工拼(pin)裝(zhuang)順序(xu),拼(pin)裝(zhuang)好首圈(quan)波(bo)紋(wen)管(guan)(guan)圖36偶數(shu)、奇(qi)(qi)數(shu)斷(duan)面(mian)交(jiao)替拼(pin)裝(zhuang)順序(xu)
4、加強斷面拼裝
當波紋管涵直徑較大(da)、填(tian)土高度較高時,必須設置加(jia)強管片,稱為加(jia)強圈”,加(jia)強斷面(mian)的管片安裝工序。
