大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝(zhuang)支(zhi)架:搭設(she)腳(jiao)手(shou)架根(gen)據波(bo)紋(wen)(wen)管的直(zhi)徑提前確(que)定，采用管扣(kou)連(lian)接(jie)鋼管的方式搭設(she)腳(jiao)手(shou)架，形式分(fen)A型和B型腳(jiao)手(shou)架長度一般(ban)長25m、克(ke)0、6m、高(gao)為(wei)2d3(d為(wei)波(bo)紋(wen)(wen)管直(zhi)徑)，B型腳(jiao)手(shou)架一般(ban)克(ke)為(wei)25m高(gao)依據波(bo)紋(wen)(wen)管直(zhi)徑大(da)小拼裝(zhuang)接(jie)縫位(wei)置確(que)定尺寸。腳(jiao)手(shou)架按上述(shu)尺寸搭設(she)便于(yu)施工、

2、拼裝類型與搭接(jie)方式：拼裝以(yi)中心(xin)軸線為基(ji)準，由中心(xin)向兩(liang)端(duan)對稱(cheng)進行安裝，直至兩(liang)端(duan)。1斷面(奇數斷面)、Ⅱ斷面(偶(ou)數斷面)、加強斷面(偶(ou)數斷管管片）

3、波紋管(guan)拼裝(zhuang)(zhuang)(zhuang)(zhuang)：采用刻槽法施工(gong)的地基，安裝(zhuang)(zhuang)(zhuang)(zhuang)吊車依據刻槽深度，依次安裝(zhuang)(zhuang)(zhuang)(zhuang)底(di)部管(guan)片。底(di)部管(guan)片安裝(zhuang)(zhuang)(zhuang)(zhuang)完成(cheng)后(hou)對剩余管(guan)片進行安裝(zhuang)(zhuang)(zhuang)(zhuang)。管(guan)片安裝(zhuang)(zhuang)(zhuang)(zhuang)同平基上的鋼波紋管(guan)施工(gong)。

鋼波紋管

首圈(quan)(quan)波(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)圈(quan)(quan)為奇數斷面(mian)，拼裝(zhuang)(zhuang)時應將管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)立(li)于地上(shang)(shang)安裝(zhuang)(zhuang)，使(shi)用(yong)(yong)(yong)(yong)鐵(tie)鉤的(de)一端(duan)勾住I斷面(mian)片(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)(luo)絲(si)囗，用(yong)(yong)(yong)(yong)12噸的(de)吊車(che)勾住鐵(tie)鉤的(de)另一端(duan)，將波(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)立(li)于墊(dian)層上(shang)(shang)，然后(hou)使(shi)用(yong)(yong)(yong)(yong)同樣的(de)辦(ban)法將第二片(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)按圖3、21斷面(mian)所示的(de)搭接(jie)方式放(fang)置，使(shi)用(yong)(yong)(yong)(yong)撬棍將管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)的(de)螺(luo)(luo)(luo)栓(shuan)口對齊，將提前準(zhun)備好的(de)螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋部涂上(shang)(shang)渢滑劑(ji)，由內(nei)冋外插入孔位(wei)；波(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)外側套(tao)上(shang)(shang)凹墊(dian)圈(quan)(quan)或凸(tu)墊(dian)圈(quan)(quan)，遇波(bo)(bo)使(shi)用(yong)(yong)(yong)(yong)凸(tu)墊(dian)圈(quan)(quan)，遇波(bo)(bo)峰使(shi)用(yong)(yong)(yong)(yong)凹墊(dian)圈(quan)(quan)墊(dian)圈(quan)(quan)外側旋(xuan)上(shang)(shang)螺(luo)(luo)(luo)母，在用(yong)(yong)(yong)(yong)套(tao)筒扳手(shou)預緊螺(luo)(luo)(luo)母，然后(hou)使(shi)用(yong)(yong)(yong)(yong)電動(dong)扳手(shou)緊固螺(luo)(luo)(luo)母兩塊板(ban)片(pian)(pian)洤全部安裝(zhuang)(zhuang)完畢;波(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)的(de)螺(luo)(luo)(luo)栓(shuan)安裝(zhuang)(zhuang)完畢后(hou)，需采用(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)注(zhu)膠槍于端(duan)部接(jie)合處(chu)、緊回件連(lian)接(jie)的(de)螺(luo)(luo)(luo)栓(shuan)孔空(kong)隙處(chu)涂抹中性硅(gui)酮耐(nai)候膠。緊接(jie)著按2#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)的(de)施工拼裝(zhuang)(zhuang)順序(xu)，拼裝(zhuang)(zhuang)好首圈(quan)(quan)波(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)圖36偶數、奇數斷面(mian)交替拼裝(zhuang)(zhuang)順序(xu)

4、加強斷面拼裝

當波紋管涵直徑較(jiao)(jiao)大、填土高度較(jiao)(jiao)高時(shi)，必須設置(zhi)加強(qiang)(qiang)管片(pian)，稱為加強(qiang)(qiang)圈”，加強(qiang)(qiang)斷(duan)面的管片(pian)安裝(zhuang)工序。
