大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝支架(jia)(jia):搭設腳手(shou)架(jia)(jia)根(gen)據波(bo)紋管(guan)(guan)(guan)的(de)直(zhi)徑提前確定(ding)，采用(yong)管(guan)(guan)(guan)扣連接(jie)鋼管(guan)(guan)(guan)的(de)方式搭設腳手(shou)架(jia)(jia)，形式分A型(xing)和B型(xing)腳手(shou)架(jia)(jia)長(chang)度一般(ban)長(chang)25m、克0、6m、高為2d3(d為波(bo)紋管(guan)(guan)(guan)直(zhi)徑)，B型(xing)腳手(shou)架(jia)(jia)一般(ban)克為25m高依據波(bo)紋管(guan)(guan)(guan)直(zhi)徑大小拼裝接(jie)縫位置確定(ding)尺(chi)寸(cun)。腳手(shou)架(jia)(jia)按(an)上述尺(chi)寸(cun)搭設便于施工、

2、拼裝(zhuang)類型與搭接方式：拼裝(zhuang)以中(zhong)心軸線為基(ji)準(zhun)，由中(zhong)心向(xiang)兩端(duan)對(dui)稱(cheng)進行安裝(zhuang)，直至兩端(duan)。1斷(duan)(duan)面(奇數(shu)斷(duan)(duan)面)、Ⅱ斷(duan)(duan)面(偶數(shu)斷(duan)(duan)面)、加強(qiang)斷(duan)(duan)面(偶數(shu)斷(duan)(duan)管(guan)管(guan)片）

3、波(bo)(bo)紋(wen)管拼裝(zhuang)：采用刻槽法施工的地(di)基，安裝(zhuang)吊車依據刻槽深度，依次安裝(zhuang)底部管片(pian)。底部管片(pian)安裝(zhuang)完成后(hou)對剩余管片(pian)進行(xing)安裝(zhuang)。管片(pian)安裝(zhuang)同平基上的鋼波(bo)(bo)紋(wen)管施工。

鋼波紋管

首圈波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)圈為奇數(shu)斷(duan)面，拼裝時應將(jiang)(jiang)管(guan)(guan)片(pian)(pian)(pian)立(li)于(yu)地上(shang)安(an)裝，使(shi)用(yong)(yong)鐵(tie)鉤的一端(duan)勾住(zhu)I斷(duan)面片(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)絲囗，用(yong)(yong)12噸的吊車勾住(zhu)鐵(tie)鉤的另一端(duan)，將(jiang)(jiang)波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)片(pian)(pian)(pian)立(li)于(yu)墊層上(shang)，然后(hou)使(shi)用(yong)(yong)同樣的辦法將(jiang)(jiang)第二(er)片(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)按圖3、21斷(duan)面所示的搭接方式放(fang)置，使(shi)用(yong)(yong)撬棍將(jiang)(jiang)管(guan)(guan)片(pian)(pian)(pian)的螺(luo)(luo)栓口對齊，將(jiang)(jiang)提(ti)前準(zhun)備好的螺(luo)(luo)栓螺(luo)(luo)紋(wen)(wen)部涂上(shang)渢滑劑，由內冋外(wai)插入孔位(wei)；波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)外(wai)側(ce)套上(shang)凹墊圈或凸墊圈，遇(yu)波(bo)(bo)(bo)(bo)使(shi)用(yong)(yong)凸墊圈，遇(yu)波(bo)(bo)(bo)(bo)峰使(shi)用(yong)(yong)凹墊圈墊圈外(wai)側(ce)旋上(shang)螺(luo)(luo)母(mu)，在用(yong)(yong)套筒扳(ban)手預緊螺(luo)(luo)母(mu)，然后(hou)使(shi)用(yong)(yong)電動扳(ban)手緊固(gu)螺(luo)(luo)母(mu)兩塊板(ban)片(pian)(pian)(pian)洤全(quan)部安(an)裝完畢;波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)的螺(luo)(luo)栓安(an)裝完畢后(hou)，需采用(yong)(yong)專用(yong)(yong)注膠槍于(yu)端(duan)部接合處、緊回件連接的螺(luo)(luo)栓孔空隙處涂抹中(zhong)性硅酮耐候膠。緊接著按2#管(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)片(pian)(pian)(pian)的施工拼裝順(shun)序(xu)，拼裝好首圈波(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)圖36偶數(shu)、奇數(shu)斷(duan)面交替(ti)拼裝順(shun)序(xu)

4、加強斷面拼裝

當(dang)波紋管涵直徑(jing)較大(da)、填土高度較高時(shi)，必須設置加(jia)(jia)強(qiang)管片(pian)，稱(cheng)為加(jia)(jia)強(qiang)圈”，加(jia)(jia)強(qiang)斷(duan)面的管片(pian)安裝工序。
