大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼(pin)裝(zhuang)支(zhi)架(jia):搭(da)設腳(jiao)手(shou)架(jia)根(gen)據波(bo)(bo)紋管(guan)的(de)直(zhi)(zhi)徑(jing)提前確定，采用(yong)管(guan)扣連接鋼管(guan)的(de)方式搭(da)設腳(jiao)手(shou)架(jia)，形式分A型(xing)和B型(xing)腳(jiao)手(shou)架(jia)長度一(yi)(yi)般長25m、克(ke)0、6m、高為2d3(d為波(bo)(bo)紋管(guan)直(zhi)(zhi)徑(jing))，B型(xing)腳(jiao)手(shou)架(jia)一(yi)(yi)般克(ke)為25m高依(yi)據波(bo)(bo)紋管(guan)直(zhi)(zhi)徑(jing)大(da)小拼(pin)裝(zhuang)接縫位置確定尺寸。腳(jiao)手(shou)架(jia)按上述尺寸搭(da)設便于(yu)施工、

2、拼(pin)裝類型與(yu)搭接方式：拼(pin)裝以中(zhong)心(xin)軸線為基準(zhun)，由(you)中(zhong)心(xin)向(xiang)兩(liang)端對稱進行(xing)安裝，直至兩(liang)端。1斷(duan)(duan)面(mian)(mian)(奇數(shu)斷(duan)(duan)面(mian)(mian))、Ⅱ斷(duan)(duan)面(mian)(mian)(偶數(shu)斷(duan)(duan)面(mian)(mian))、加強斷(duan)(duan)面(mian)(mian)(偶數(shu)斷(duan)(duan)管管片）

3、波(bo)紋(wen)管(guan)拼裝(zhuang)：采用刻槽法施(shi)工的地基(ji)，安(an)裝(zhuang)吊車依據刻槽深度，依次安(an)裝(zhuang)底部管(guan)片(pian)。底部管(guan)片(pian)安(an)裝(zhuang)完成后(hou)對剩余(yu)管(guan)片(pian)進行安(an)裝(zhuang)。管(guan)片(pian)安(an)裝(zhuang)同(tong)平基(ji)上的鋼(gang)波(bo)紋(wen)管(guan)施(shi)工。

首(shou)圈(quan)(quan)波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)圈(quan)(quan)為(wei)奇數斷(duan)面(mian)(mian)，拼(pin)裝(zhuang)(zhuang)時應將管(guan)(guan)(guan)片(pian)立(li)(li)于(yu)地上(shang)安裝(zhuang)(zhuang)，使(shi)用(yong)鐵(tie)鉤(gou)的一端勾住I斷(duan)面(mian)(mian)片(pian)(1#管(guan)(guan)(guan)片(pian))波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)螺(luo)絲囗，用(yong)12噸(dun)的吊車勾住鐵(tie)鉤(gou)的另一端，將波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)片(pian)立(li)(li)于(yu)墊(dian)(dian)層上(shang)，然后使(shi)用(yong)同樣(yang)的辦法將第二片(pian)(6#管(guan)(guan)(guan)片(pian))波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)按圖3、21斷(duan)面(mian)(mian)所(suo)示(shi)的搭接(jie)方式放置(zhi)，使(shi)用(yong)撬(qiao)棍將管(guan)(guan)(guan)片(pian)的螺(luo)栓口對(dui)齊(qi)，將提前準備好(hao)的螺(luo)栓螺(luo)紋(wen)(wen)部涂(tu)上(shang)渢滑(hua)劑，由內冋外插(cha)入孔位；波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)外側套上(shang)凹墊(dian)(dian)圈(quan)(quan)或凸墊(dian)(dian)圈(quan)(quan)，遇(yu)波(bo)(bo)(bo)(bo)使(shi)用(yong)凸墊(dian)(dian)圈(quan)(quan)，遇(yu)波(bo)(bo)(bo)(bo)峰使(shi)用(yong)凹墊(dian)(dian)圈(quan)(quan)墊(dian)(dian)圈(quan)(quan)外側旋(xuan)上(shang)螺(luo)母，在用(yong)套筒扳(ban)手預緊(jin)螺(luo)母，然后使(shi)用(yong)電動扳(ban)手緊(jin)固螺(luo)母兩塊板片(pian)洤(quan)全(quan)部安裝(zhuang)(zhuang)完畢(bi);波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)的螺(luo)栓安裝(zhuang)(zhuang)完畢(bi)后，需采用(yong)專用(yong)注膠(jiao)槍于(yu)端部接(jie)合處、緊(jin)回件連(lian)接(jie)的螺(luo)栓孔空隙處涂(tu)抹(mo)中性硅酮耐候膠(jiao)。緊(jin)接(jie)著按2#管(guan)(guan)(guan)片(pian)、5#管(guan)(guan)(guan)片(pian)、3#管(guan)(guan)(guan)片(pian)、4#管(guan)(guan)(guan)片(pian)的施(shi)工拼(pin)裝(zhuang)(zhuang)順序，拼(pin)裝(zhuang)(zhuang)好(hao)首(shou)圈(quan)(quan)波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)圖36偶(ou)數、奇數斷(duan)面(mian)(mian)交(jiao)替拼(pin)裝(zhuang)(zhuang)順序

4、加強斷面拼裝

當(dang)波紋管(guan)涵直徑較大、填土高度(du)較高時，必(bi)須(xu)設置加(jia)(jia)強(qiang)管(guan)片，稱為加(jia)(jia)強(qiang)圈”，加(jia)(jia)強(qiang)斷面的管(guan)片安裝工序。
