大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝(zhuang)(zhuang)支(zhi)架(jia):搭設(she)腳手(shou)(shou)(shou)架(jia)根據波紋(wen)管(guan)(guan)的直徑提前確定，采用管(guan)(guan)扣(kou)連接鋼管(guan)(guan)的方式(shi)搭設(she)腳手(shou)(shou)(shou)架(jia)，形式(shi)分A型(xing)和B型(xing)腳手(shou)(shou)(shou)架(jia)長度一般(ban)(ban)長25m、克(ke)0、6m、高(gao)為(wei)2d3(d為(wei)波紋(wen)管(guan)(guan)直徑)，B型(xing)腳手(shou)(shou)(shou)架(jia)一般(ban)(ban)克(ke)為(wei)25m高(gao)依據波紋(wen)管(guan)(guan)直徑大小(xiao)拼裝(zhuang)(zhuang)接縫位置確定尺寸。腳手(shou)(shou)(shou)架(jia)按(an)上述尺寸搭設(she)便于施工、

2、拼(pin)裝(zhuang)類型(xing)與搭接方(fang)式：拼(pin)裝(zhuang)以中(zhong)心(xin)軸線為基(ji)準，由中(zhong)心(xin)向兩端(duan)對(dui)稱進行安裝(zhuang)，直至兩端(duan)。1斷(duan)(duan)面(奇數(shu)(shu)斷(duan)(duan)面)、Ⅱ斷(duan)(duan)面(偶(ou)數(shu)(shu)斷(duan)(duan)面)、加(jia)強斷(duan)(duan)面(偶(ou)數(shu)(shu)斷(duan)(duan)管管片(pian)）

3、波(bo)紋管(guan)(guan)拼裝：采用刻槽法(fa)施工的(de)地基(ji)(ji)，安裝吊(diao)車依(yi)據刻槽深度，依(yi)次安裝底部管(guan)(guan)片(pian)。底部管(guan)(guan)片(pian)安裝完成后(hou)對剩余管(guan)(guan)片(pian)進行安裝。管(guan)(guan)片(pian)安裝同平(ping)基(ji)(ji)上的(de)鋼波(bo)紋管(guan)(guan)施工。

首(shou)圈波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)圈為奇數(shu)斷面，拼(pin)裝(zhuang)(zhuang)(zhuang)(zhuang)時應(ying)將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)地上(shang)安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)，使(shi)(shi)用(yong)(yong)鐵鉤的(de)(de)一(yi)端勾住(zhu)(zhu)I斷面片(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)絲囗，用(yong)(yong)12噸(dun)的(de)(de)吊車勾住(zhu)(zhu)鐵鉤的(de)(de)另一(yi)端，將(jiang)波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)墊(dian)層上(shang)，然(ran)后(hou)使(shi)(shi)用(yong)(yong)同樣的(de)(de)辦(ban)法將(jiang)第二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)按圖(tu)3、21斷面所(suo)示(shi)的(de)(de)搭接(jie)方式放置，使(shi)(shi)用(yong)(yong)撬棍(gun)將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)螺(luo)栓(shuan)口對齊，將(jiang)提(ti)前準(zhun)備好的(de)(de)螺(luo)栓(shuan)螺(luo)紋(wen)(wen)部(bu)涂(tu)(tu)上(shang)渢(feng)滑劑，由內冋外(wai)插(cha)入孔(kong)位(wei)；波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)外(wai)側(ce)套上(shang)凹墊(dian)圈或凸墊(dian)圈，遇波(bo)(bo)(bo)(bo)(bo)使(shi)(shi)用(yong)(yong)凸墊(dian)圈，遇波(bo)(bo)(bo)(bo)(bo)峰使(shi)(shi)用(yong)(yong)凹墊(dian)圈墊(dian)圈外(wai)側(ce)旋上(shang)螺(luo)母，在用(yong)(yong)套筒扳手預(yu)緊(jin)螺(luo)母，然(ran)后(hou)使(shi)(shi)用(yong)(yong)電動(dong)扳手緊(jin)固螺(luo)母兩塊板片(pian)(pian)(pian)(pian)洤全部(bu)安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)完畢;波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)的(de)(de)螺(luo)栓(shuan)安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)完畢后(hou)，需采用(yong)(yong)專用(yong)(yong)注(zhu)膠槍于(yu)端部(bu)接(jie)合處、緊(jin)回件連(lian)接(jie)的(de)(de)螺(luo)栓(shuan)孔(kong)空隙處涂(tu)(tu)抹中性(xing)硅酮耐候膠。緊(jin)接(jie)著按2#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)施工拼(pin)裝(zhuang)(zhuang)(zhuang)(zhuang)順(shun)序(xu)，拼(pin)裝(zhuang)(zhuang)(zhuang)(zhuang)好首(shou)圈波(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)圖(tu)36偶數(shu)、奇數(shu)斷面交替拼(pin)裝(zhuang)(zhuang)(zhuang)(zhuang)順(shun)序(xu)

4、加強斷面拼裝

當(dang)波紋管涵直徑(jing)較大、填(tian)土高度(du)較高時，必須設置加強(qiang)管片，稱(cheng)為加強(qiang)圈”，加強(qiang)斷面的(de)管片安裝工(gong)序(xu)。
