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)(shou)架根據(ju)波(bo)紋(wen)(wen)管的(de)直徑提前確定，采用管扣連接鋼管的(de)方式(shi)搭(da)設(she)腳手(shou)(shou)架，形式(shi)分(fen)A型和B型腳手(shou)(shou)架長度一(yi)般長25m、克0、6m、高(gao)為(wei)2d3(d為(wei)波(bo)紋(wen)(wen)管直徑)，B型腳手(shou)(shou)架一(yi)般克為(wei)25m高(gao)依據(ju)波(bo)紋(wen)(wen)管直徑大小(xiao)拼裝接縫(feng)位置確定尺(chi)(chi)寸。腳手(shou)(shou)架按(an)上(shang)述尺(chi)(chi)寸搭(da)設(she)便于(yu)施工(gong)、

2、拼裝(zhuang)類型與搭接(jie)方式：拼裝(zhuang)以中(zhong)心(xin)軸線為基準，由中(zhong)心(xin)向兩(liang)(liang)端(duan)對稱進(jin)行安裝(zhuang)，直至(zhi)兩(liang)(liang)端(duan)。1斷(duan)(duan)面(mian)(奇數(shu)(shu)斷(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)面(mian)(偶(ou)數(shu)(shu)斷(duan)(duan)面(mian))、加強斷(duan)(duan)面(mian)(偶(ou)數(shu)(shu)斷(duan)(duan)管管片）

3、波紋(wen)管(guan)(guan)(guan)(guan)拼裝(zhuang)(zhuang)(zhuang)：采用刻(ke)槽(cao)法施(shi)工(gong)的(de)地基，安裝(zhuang)(zhuang)(zhuang)吊車依據刻(ke)槽(cao)深度(du)，依次安裝(zhuang)(zhuang)(zhuang)底部管(guan)(guan)(guan)(guan)片(pian)。底部管(guan)(guan)(guan)(guan)片(pian)安裝(zhuang)(zhuang)(zhuang)完成后對剩余管(guan)(guan)(guan)(guan)片(pian)進行安裝(zhuang)(zhuang)(zhuang)。管(guan)(guan)(guan)(guan)片(pian)安裝(zhuang)(zhuang)(zhuang)同平基上的(de)鋼波紋(wen)管(guan)(guan)(guan)(guan)施(shi)工(gong)。

首圈(quan)波(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)圈(quan)為奇數斷面，拼裝時應將管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立(li)于(yu)地上(shang)安(an)裝，使(shi)(shi)(shi)用(yong)鐵鉤(gou)的(de)(de)一(yi)端勾住I斷面片(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)絲囗，用(yong)12噸的(de)(de)吊車勾住鐵鉤(gou)的(de)(de)另一(yi)端，將波(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立(li)于(yu)墊層上(shang)，然后(hou)使(shi)(shi)(shi)用(yong)同樣的(de)(de)辦(ban)法將第二片(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)按圖(tu)3、21斷面所示的(de)(de)搭接(jie)(jie)方式放(fang)置，使(shi)(shi)(shi)用(yong)撬(qiao)棍(gun)將管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)螺(luo)栓(shuan)口對(dui)齊，將提(ti)前準備好(hao)的(de)(de)螺(luo)栓(shuan)螺(luo)紋部涂上(shang)渢滑(hua)劑(ji)，由(you)內(nei)冋(jiong)外(wai)插入孔(kong)位(wei)；波(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)外(wai)側套上(shang)凹墊圈(quan)或凸(tu)墊圈(quan)，遇波(bo)(bo)(bo)使(shi)(shi)(shi)用(yong)凸(tu)墊圈(quan)，遇波(bo)(bo)(bo)峰使(shi)(shi)(shi)用(yong)凹墊圈(quan)墊圈(quan)外(wai)側旋上(shang)螺(luo)母，在(zai)用(yong)套筒扳手預緊(jin)螺(luo)母，然后(hou)使(shi)(shi)(shi)用(yong)電動扳手緊(jin)固螺(luo)母兩塊板(ban)片(pian)(pian)(pian)洤全(quan)部安(an)裝完(wan)畢;波(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)的(de)(de)螺(luo)栓(shuan)安(an)裝完(wan)畢后(hou)，需采用(yong)專用(yong)注膠槍于(yu)端部接(jie)(jie)合處、緊(jin)回件連接(jie)(jie)的(de)(de)螺(luo)栓(shuan)孔(kong)空隙處涂抹(mo)中(zhong)性硅(gui)酮耐候膠。緊(jin)接(jie)(jie)著(zhu)按2#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)施工拼裝順(shun)序，拼裝好(hao)首圈(quan)波(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)圖(tu)36偶數、奇數斷面交替拼裝順(shun)序

4、加強斷面拼裝

當波紋(wen)管(guan)涵直徑較大(da)、填(tian)土高度(du)較高時(shi)，必(bi)須(xu)設(she)置加(jia)強(qiang)(qiang)管(guan)片，稱(cheng)為加(jia)強(qiang)(qiang)圈”，加(jia)強(qiang)(qiang)斷面的(de)管(guan)片安裝工序。
