大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝(zhuang)支架(jia)(jia):搭(da)設(she)腳(jiao)手(shou)架(jia)(jia)根據波紋(wen)管的直(zhi)徑提前確定(ding)，采用管扣連(lian)接(jie)(jie)鋼管的方式(shi)(shi)搭(da)設(she)腳(jiao)手(shou)架(jia)(jia)，形式(shi)(shi)分A型和B型腳(jiao)手(shou)架(jia)(jia)長度一般(ban)長25m、克(ke)(ke)0、6m、高為(wei)2d3(d為(wei)波紋(wen)管直(zhi)徑)，B型腳(jiao)手(shou)架(jia)(jia)一般(ban)克(ke)(ke)為(wei)25m高依據波紋(wen)管直(zhi)徑大小(xiao)拼裝(zhuang)接(jie)(jie)縫位置(zhi)確定(ding)尺寸。腳(jiao)手(shou)架(jia)(jia)按(an)上述尺寸搭(da)設(she)便于施工、

2、拼裝類型(xing)與搭接方式：拼裝以中(zhong)心(xin)軸(zhou)線為基(ji)準，由中(zhong)心(xin)向兩端對稱進(jin)行安裝，直至兩端。1斷面(奇數斷面)、Ⅱ斷面(偶數斷面)、加強斷面(偶數斷管(guan)管(guan)片）

3、波紋(wen)管拼裝(zhuang)(zhuang)(zhuang)：采用刻槽法施(shi)工的(de)地基(ji)，安(an)(an)裝(zhuang)(zhuang)(zhuang)吊車依(yi)據(ju)刻槽深度，依(yi)次安(an)(an)裝(zhuang)(zhuang)(zhuang)底部管片。底部管片安(an)(an)裝(zhuang)(zhuang)(zhuang)完成后對剩(sheng)余管片進(jin)行安(an)(an)裝(zhuang)(zhuang)(zhuang)。管片安(an)(an)裝(zhuang)(zhuang)(zhuang)同平基(ji)上的(de)鋼波紋(wen)管施(shi)工。

首(shou)圈(quan)波(bo)紋(wen)管(guan)(guan)(guan)圈(quan)為(wei)奇數斷(duan)(duan)面，拼(pin)裝(zhuang)時應(ying)將管(guan)(guan)(guan)片(pian)立(li)于(yu)地上(shang)安裝(zhuang)，使(shi)(shi)用(yong)(yong)(yong)鐵鉤(gou)(gou)的(de)(de)一端(duan)勾(gou)住I斷(duan)(duan)面片(pian)(1#管(guan)(guan)(guan)片(pian))波(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)螺(luo)絲囗，用(yong)(yong)(yong)12噸(dun)的(de)(de)吊車勾(gou)住鐵鉤(gou)(gou)的(de)(de)另一端(duan)，將波(bo)紋(wen)管(guan)(guan)(guan)片(pian)立(li)于(yu)墊層上(shang)，然后(hou)使(shi)(shi)用(yong)(yong)(yong)同(tong)樣的(de)(de)辦法將第二片(pian)(6#管(guan)(guan)(guan)片(pian))波(bo)紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)按(an)圖3、21斷(duan)(duan)面所示的(de)(de)搭接方式放置，使(shi)(shi)用(yong)(yong)(yong)撬(qiao)棍(gun)將管(guan)(guan)(guan)片(pian)的(de)(de)螺(luo)栓口對齊，將提前準(zhun)備好(hao)的(de)(de)螺(luo)栓螺(luo)紋(wen)部涂上(shang)渢滑劑(ji)，由(you)內冋外(wai)插入(ru)孔(kong)位(wei)；波(bo)紋(wen)管(guan)(guan)(guan)外(wai)側(ce)套上(shang)凹(ao)墊圈(quan)或凸墊圈(quan)，遇波(bo)使(shi)(shi)用(yong)(yong)(yong)凸墊圈(quan)，遇波(bo)峰使(shi)(shi)用(yong)(yong)(yong)凹(ao)墊圈(quan)墊圈(quan)外(wai)側(ce)旋上(shang)螺(luo)母(mu)(mu)，在用(yong)(yong)(yong)套筒(tong)扳(ban)手預緊(jin)(jin)螺(luo)母(mu)(mu)，然后(hou)使(shi)(shi)用(yong)(yong)(yong)電動扳(ban)手緊(jin)(jin)固螺(luo)母(mu)(mu)兩塊板片(pian)洤全部安裝(zhuang)完畢;波(bo)紋(wen)管(guan)(guan)(guan)的(de)(de)螺(luo)栓安裝(zhuang)完畢后(hou)，需采用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠槍于(yu)端(duan)部接合處、緊(jin)(jin)回件(jian)連接的(de)(de)螺(luo)栓孔(kong)空(kong)隙處涂抹(mo)中(zhong)性(xing)硅酮耐(nai)候膠。緊(jin)(jin)接著按(an)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(de)(de)施(shi)工拼(pin)裝(zhuang)順(shun)序(xu)，拼(pin)裝(zhuang)好(hao)首(shou)圈(quan)波(bo)紋(wen)管(guan)(guan)(guan)圖36偶數、奇數斷(duan)(duan)面交(jiao)替拼(pin)裝(zhuang)順(shun)序(xu)

4、加強斷面拼裝

當波紋管(guan)涵直徑(jing)較(jiao)大(da)、填土(tu)高(gao)(gao)度較(jiao)高(gao)(gao)時(shi)，必須設(she)置加強(qiang)管(guan)片(pian)，稱為加強(qiang)圈”，加強(qiang)斷面的管(guan)片(pian)安裝工(gong)序。
