大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)(she)拼裝(zhuang)支架(jia)(jia)(jia):搭(da)設(she)(she)腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)根據波(bo)紋管(guan)的直(zhi)徑提前確定，采用(yong)管(guan)扣連接(jie)鋼管(guan)的方式(shi)搭(da)設(she)(she)腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)，形式(shi)分(fen)A型(xing)和B型(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)長度(du)一般長25m、克0、6m、高為(wei)(wei)2d3(d為(wei)(wei)波(bo)紋管(guan)直(zhi)徑)，B型(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)一般克為(wei)(wei)25m高依據波(bo)紋管(guan)直(zhi)徑大小拼裝(zhuang)接(jie)縫(feng)位置確定尺(chi)(chi)寸。腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)按(an)上(shang)述(shu)尺(chi)(chi)寸搭(da)設(she)(she)便于施工、

2、拼(pin)裝類型(xing)與搭接方式：拼(pin)裝以中心(xin)軸線(xian)為基(ji)準，由中心(xin)向兩(liang)端(duan)(duan)對(dui)稱進行(xing)安裝，直至兩(liang)端(duan)(duan)。1斷(duan)面(mian)(mian)(奇數(shu)斷(duan)面(mian)(mian))、Ⅱ斷(duan)面(mian)(mian)(偶(ou)數(shu)斷(duan)面(mian)(mian))、加強斷(duan)面(mian)(mian)(偶(ou)數(shu)斷(duan)管(guan)管(guan)片）

3、波(bo)紋管(guan)(guan)拼裝(zhuang)(zhuang)：采(cai)用刻槽法施工(gong)的地基(ji)，安(an)裝(zhuang)(zhuang)吊車依據刻槽深度，依次安(an)裝(zhuang)(zhuang)底部管(guan)(guan)片(pian)。底部管(guan)(guan)片(pian)安(an)裝(zhuang)(zhuang)完(wan)成后對剩余(yu)管(guan)(guan)片(pian)進行安(an)裝(zhuang)(zhuang)。管(guan)(guan)片(pian)安(an)裝(zhuang)(zhuang)同平基(ji)上的鋼波(bo)紋管(guan)(guan)施工(gong)。

首圈(quan)(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)圈(quan)(quan)為(wei)奇(qi)(qi)數(shu)斷面，拼裝(zhuang)時應將(jiang)(jiang)(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)立于地上(shang)(shang)安(an)裝(zhuang)，使(shi)用(yong)(yong)鐵鉤的一端勾住(zhu)I斷面片(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)螺(luo)絲囗，用(yong)(yong)12噸的吊車勾住(zhu)鐵鉤的另一端，將(jiang)(jiang)(jiang)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)立于墊(dian)層上(shang)(shang)，然后使(shi)用(yong)(yong)同(tong)樣的辦法將(jiang)(jiang)(jiang)第二(er)片(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)按(an)圖3、21斷面所示的搭(da)接(jie)方式放置，使(shi)用(yong)(yong)撬棍將(jiang)(jiang)(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)的螺(luo)栓(shuan)(shuan)口對齊，將(jiang)(jiang)(jiang)提(ti)前準備好的螺(luo)栓(shuan)(shuan)螺(luo)紋(wen)部涂上(shang)(shang)渢滑(hua)劑，由內冋外插入孔位(wei)；波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)外側(ce)套上(shang)(shang)凹墊(dian)圈(quan)(quan)或凸墊(dian)圈(quan)(quan)，遇(yu)波(bo)(bo)使(shi)用(yong)(yong)凸墊(dian)圈(quan)(quan)，遇(yu)波(bo)(bo)峰使(shi)用(yong)(yong)凹墊(dian)圈(quan)(quan)墊(dian)圈(quan)(quan)外側(ce)旋上(shang)(shang)螺(luo)母(mu)，在用(yong)(yong)套筒扳(ban)手預(yu)緊(jin)螺(luo)母(mu)，然后使(shi)用(yong)(yong)電動扳(ban)手緊(jin)固螺(luo)母(mu)兩塊板片(pian)(pian)洤(quan)全部安(an)裝(zhuang)完畢;波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)的螺(luo)栓(shuan)(shuan)安(an)裝(zhuang)完畢后，需采用(yong)(yong)專用(yong)(yong)注膠槍于端部接(jie)合(he)處、緊(jin)回件連接(jie)的螺(luo)栓(shuan)(shuan)孔空隙處涂抹中性硅酮耐候膠。緊(jin)接(jie)著按(an)2#管(guan)(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)的施工拼裝(zhuang)順(shun)序(xu)，拼裝(zhuang)好首圈(quan)(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)圖36偶數(shu)、奇(qi)(qi)數(shu)斷面交替拼裝(zhuang)順(shun)序(xu)

4、加強斷面拼裝

當(dang)波紋管(guan)(guan)涵直徑(jing)較大、填土高度較高時，必須設(she)置加(jia)強(qiang)管(guan)(guan)片，稱為(wei)加(jia)強(qiang)圈”，加(jia)強(qiang)斷(duan)面的(de)管(guan)(guan)片安裝工序。
