大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)(she)拼裝(zhuang)支架(jia):搭設(she)(she)腳手(shou)架(jia)根據波(bo)紋管(guan)的直徑提前確定，采用(yong)管(guan)扣連(lian)接(jie)鋼(gang)管(guan)的方式(shi)搭設(she)(she)腳手(shou)架(jia)，形式(shi)分A型(xing)(xing)(xing)和B型(xing)(xing)(xing)腳手(shou)架(jia)長度一(yi)般長25m、克0、6m、高為(wei)2d3(d為(wei)波(bo)紋管(guan)直徑)，B型(xing)(xing)(xing)腳手(shou)架(jia)一(yi)般克為(wei)25m高依(yi)據波(bo)紋管(guan)直徑大小拼裝(zhuang)接(jie)縫位置(zhi)確定尺寸。腳手(shou)架(jia)按上述尺寸搭設(she)(she)便于(yu)施(shi)工(gong)、

2、拼(pin)裝(zhuang)類(lei)型與搭(da)接方式：拼(pin)裝(zhuang)以中心(xin)軸線為基準(zhun)，由中心(xin)向兩(liang)端對(dui)稱進行安裝(zhuang)，直至(zhi)兩(liang)端。1斷(duan)面(奇數(shu)(shu)斷(duan)面)、Ⅱ斷(duan)面(偶(ou)數(shu)(shu)斷(duan)面)、加強斷(duan)面(偶(ou)數(shu)(shu)斷(duan)管(guan)(guan)管(guan)(guan)片(pian)）

3、波(bo)紋(wen)管(guan)拼裝：采用刻槽法施工的地基，安(an)裝吊車依據刻槽深度，依次安(an)裝底部管(guan)片。底部管(guan)片安(an)裝完成后對剩余(yu)管(guan)片進行安(an)裝。管(guan)片安(an)裝同平基上的鋼波(bo)紋(wen)管(guan)施工。

首圈(quan)(quan)(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)圈(quan)(quan)(quan)為奇(qi)數斷(duan)面(mian)，拼裝(zhuang)(zhuang)(zhuang)時應將(jiang)管(guan)(guan)(guan)片(pian)(pian)立(li)于地上(shang)安裝(zhuang)(zhuang)(zhuang)，使用(yong)(yong)鐵(tie)鉤的(de)(de)(de)一端勾住(zhu)I斷(duan)面(mian)片(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)螺(luo)絲囗(wei)，用(yong)(yong)12噸的(de)(de)(de)吊車勾住(zhu)鐵(tie)鉤的(de)(de)(de)另一端，將(jiang)波(bo)(bo)紋(wen)管(guan)(guan)(guan)片(pian)(pian)立(li)于墊(dian)層(ceng)上(shang)，然后(hou)(hou)使用(yong)(yong)同樣(yang)的(de)(de)(de)辦(ban)法將(jiang)第二片(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)按(an)圖(tu)3、21斷(duan)面(mian)所示的(de)(de)(de)搭接(jie)方(fang)式放置，使用(yong)(yong)撬棍將(jiang)管(guan)(guan)(guan)片(pian)(pian)的(de)(de)(de)螺(luo)栓口對齊，將(jiang)提前準(zhun)備好(hao)(hao)的(de)(de)(de)螺(luo)栓螺(luo)紋(wen)部(bu)涂(tu)上(shang)渢滑劑，由內冋外插入(ru)孔(kong)位；波(bo)(bo)紋(wen)管(guan)(guan)(guan)外側套上(shang)凹墊(dian)圈(quan)(quan)(quan)或凸墊(dian)圈(quan)(quan)(quan)，遇波(bo)(bo)使用(yong)(yong)凸墊(dian)圈(quan)(quan)(quan)，遇波(bo)(bo)峰使用(yong)(yong)凹墊(dian)圈(quan)(quan)(quan)墊(dian)圈(quan)(quan)(quan)外側旋上(shang)螺(luo)母(mu)，在用(yong)(yong)套筒扳手預(yu)緊(jin)(jin)螺(luo)母(mu)，然后(hou)(hou)使用(yong)(yong)電動扳手緊(jin)(jin)固(gu)螺(luo)母(mu)兩塊板(ban)片(pian)(pian)洤(quan)全部(bu)安裝(zhuang)(zhuang)(zhuang)完畢;波(bo)(bo)紋(wen)管(guan)(guan)(guan)的(de)(de)(de)螺(luo)栓安裝(zhuang)(zhuang)(zhuang)完畢后(hou)(hou)，需(xu)采(cai)用(yong)(yong)專用(yong)(yong)注膠槍(qiang)于端部(bu)接(jie)合處、緊(jin)(jin)回件連接(jie)的(de)(de)(de)螺(luo)栓孔(kong)空隙處涂(tu)抹中(zhong)性硅酮耐候膠。緊(jin)(jin)接(jie)著按(an)2#管(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)的(de)(de)(de)施工拼裝(zhuang)(zhuang)(zhuang)順序，拼裝(zhuang)(zhuang)(zhuang)好(hao)(hao)首圈(quan)(quan)(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)圖(tu)36偶數、奇(qi)數斷(duan)面(mian)交(jiao)替拼裝(zhuang)(zhuang)(zhuang)順序

4、加強斷面拼裝

當(dang)波紋管涵(han)直徑較(jiao)大、填土(tu)高(gao)度(du)較(jiao)高(gao)時，必須設(she)置加強(qiang)管片，稱為加強(qiang)圈”，加強(qiang)斷(duan)面的管片安裝工序(xu)。
