大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設拼(pin)裝支架(jia)(jia)(jia):搭(da)(da)設腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)根(gen)據(ju)(ju)波(bo)(bo)紋(wen)管的(de)直(zhi)徑提前確定(ding)，采(cai)用管扣連接(jie)鋼管的(de)方式搭(da)(da)設腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)，形式分A型和B型腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)長度一般長25m、克(ke)0、6m、高為(wei)2d3(d為(wei)波(bo)(bo)紋(wen)管直(zhi)徑)，B型腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)一般克(ke)為(wei)25m高依據(ju)(ju)波(bo)(bo)紋(wen)管直(zhi)徑大小拼(pin)裝接(jie)縫位置確定(ding)尺(chi)寸(cun)。腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)(jia)按上述尺(chi)寸(cun)搭(da)(da)設便于施工、

2、拼(pin)裝(zhuang)類型與搭接方式：拼(pin)裝(zhuang)以中心(xin)軸線為基準，由中心(xin)向兩端對稱進行安(an)裝(zhuang)，直至兩端。1斷(duan)(duan)(duan)面(mian)(mian)(mian)(奇數(shu)斷(duan)(duan)(duan)面(mian)(mian)(mian))、Ⅱ斷(duan)(duan)(duan)面(mian)(mian)(mian)(偶數(shu)斷(duan)(duan)(duan)面(mian)(mian)(mian))、加(jia)強(qiang)斷(duan)(duan)(duan)面(mian)(mian)(mian)(偶數(shu)斷(duan)(duan)(duan)管管片）

3、波紋管(guan)(guan)拼裝(zhuang)(zhuang)(zhuang)：采用(yong)刻槽(cao)法施(shi)工的地基，安(an)(an)(an)裝(zhuang)(zhuang)(zhuang)吊車依(yi)據刻槽(cao)深度，依(yi)次安(an)(an)(an)裝(zhuang)(zhuang)(zhuang)底部(bu)管(guan)(guan)片(pian)。底部(bu)管(guan)(guan)片(pian)安(an)(an)(an)裝(zhuang)(zhuang)(zhuang)完成后對剩余(yu)管(guan)(guan)片(pian)進行安(an)(an)(an)裝(zhuang)(zhuang)(zhuang)。管(guan)(guan)片(pian)安(an)(an)(an)裝(zhuang)(zhuang)(zhuang)同平基上的鋼波紋管(guan)(guan)施(shi)工。

首圈(quan)波(bo)紋(wen)(wen)管(guan)(guan)圈(quan)為(wei)奇數(shu)(shu)斷面(mian)，拼裝(zhuang)(zhuang)時(shi)應將(jiang)管(guan)(guan)片(pian)(pian)立于(yu)地上(shang)安(an)裝(zhuang)(zhuang)，使(shi)用(yong)鐵(tie)鉤的一(yi)端(duan)勾住I斷面(mian)片(pian)(pian)(1#管(guan)(guan)片(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)螺(luo)(luo)(luo)(luo)(luo)(luo)絲囗，用(yong)12噸的吊車勾住鐵(tie)鉤的另一(yi)端(duan)，將(jiang)波(bo)紋(wen)(wen)管(guan)(guan)片(pian)(pian)立于(yu)墊(dian)層上(shang)，然后使(shi)用(yong)同(tong)樣的辦法將(jiang)第二片(pian)(pian)(6#管(guan)(guan)片(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)按圖3、21斷面(mian)所(suo)示(shi)的搭接(jie)方式放置，使(shi)用(yong)撬棍將(jiang)管(guan)(guan)片(pian)(pian)的螺(luo)(luo)(luo)(luo)(luo)(luo)栓口(kou)對齊，將(jiang)提前準備好的螺(luo)(luo)(luo)(luo)(luo)(luo)栓螺(luo)(luo)(luo)(luo)(luo)(luo)紋(wen)(wen)部(bu)涂上(shang)渢滑劑，由內冋外(wai)插入孔位(wei)；波(bo)紋(wen)(wen)管(guan)(guan)外(wai)側套上(shang)凹墊(dian)圈(quan)或(huo)凸墊(dian)圈(quan)，遇波(bo)使(shi)用(yong)凸墊(dian)圈(quan)，遇波(bo)峰使(shi)用(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外(wai)側旋(xuan)上(shang)螺(luo)(luo)(luo)(luo)(luo)(luo)母(mu)，在用(yong)套筒扳手(shou)預緊螺(luo)(luo)(luo)(luo)(luo)(luo)母(mu)，然后使(shi)用(yong)電動扳手(shou)緊固螺(luo)(luo)(luo)(luo)(luo)(luo)母(mu)兩塊板片(pian)(pian)洤全部(bu)安(an)裝(zhuang)(zhuang)完畢;波(bo)紋(wen)(wen)管(guan)(guan)的螺(luo)(luo)(luo)(luo)(luo)(luo)栓安(an)裝(zhuang)(zhuang)完畢后，需采用(yong)專(zhuan)用(yong)注膠槍于(yu)端(duan)部(bu)接(jie)合處、緊回件連接(jie)的螺(luo)(luo)(luo)(luo)(luo)(luo)栓孔空隙(xi)處涂抹中性硅酮耐候膠。緊接(jie)著按2#管(guan)(guan)片(pian)(pian)、5#管(guan)(guan)片(pian)(pian)、3#管(guan)(guan)片(pian)(pian)、4#管(guan)(guan)片(pian)(pian)的施工拼裝(zhuang)(zhuang)順(shun)(shun)序，拼裝(zhuang)(zhuang)好首圈(quan)波(bo)紋(wen)(wen)管(guan)(guan)圖36偶數(shu)(shu)、奇數(shu)(shu)斷面(mian)交(jiao)替拼裝(zhuang)(zhuang)順(shun)(shun)序

4、加強斷面拼裝

當波(bo)紋(wen)管涵直徑較(jiao)大、填土高(gao)(gao)度較(jiao)高(gao)(gao)時(shi)，必(bi)須設置加強管片，稱為加強圈”，加強斷面的管片安(an)裝工序。
