大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝支架:搭設腳手架根據波(bo)紋管的(de)直徑(jing)提前(qian)確(que)定(ding)，采用管扣連接(jie)(jie)鋼管的(de)方式搭設腳手架，形式分A型和B型腳手架長(chang)度一(yi)般長(chang)25m、克(ke)0、6m、高為2d3(d為波(bo)紋管直徑(jing))，B型腳手架一(yi)般克(ke)為25m高依據波(bo)紋管直徑(jing)大小拼裝接(jie)(jie)縫位置確(que)定(ding)尺(chi)寸(cun)。腳手架按上述(shu)尺(chi)寸(cun)搭設便于施工、

2、拼裝類型與(yu)搭(da)接(jie)方式(shi)：拼裝以中(zhong)心軸(zhou)線為(wei)基(ji)準，由(you)中(zhong)心向兩端(duan)對稱進行安裝，直至兩端(duan)。1斷面(mian)(mian)(奇(qi)數(shu)(shu)斷面(mian)(mian))、Ⅱ斷面(mian)(mian)(偶數(shu)(shu)斷面(mian)(mian))、加強斷面(mian)(mian)(偶數(shu)(shu)斷管(guan)(guan)管(guan)(guan)片）

3、波紋(wen)管(guan)拼裝：采(cai)用刻槽(cao)法(fa)施工的地基(ji)，安裝吊車依據刻槽(cao)深度，依次安裝底部(bu)管(guan)片(pian)。底部(bu)管(guan)片(pian)安裝完成后對剩余管(guan)片(pian)進行安裝。管(guan)片(pian)安裝同平基(ji)上的鋼波紋(wen)管(guan)施工。

首圈(quan)(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)圈(quan)(quan)為(wei)奇(qi)數(shu)(shu)斷(duan)(duan)面(mian)，拼(pin)(pin)裝時應將管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立(li)于地(di)上安(an)裝，使(shi)用(yong)(yong)鐵鉤的(de)(de)(de)一端(duan)勾(gou)住(zhu)I斷(duan)(duan)面(mian)片(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)(luo)絲囗，用(yong)(yong)12噸的(de)(de)(de)吊車(che)勾(gou)住(zhu)鐵鉤的(de)(de)(de)另一端(duan)，將波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立(li)于墊(dian)層(ceng)上，然后(hou)使(shi)用(yong)(yong)同樣的(de)(de)(de)辦法將第二片(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)按(an)圖(tu)3、21斷(duan)(duan)面(mian)所(suo)示的(de)(de)(de)搭接方(fang)式放(fang)置(zhi)，使(shi)用(yong)(yong)撬棍將管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)口對齊，將提前準(zhun)備(bei)好的(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋(wen)(wen)部(bu)涂上渢(feng)滑劑(ji)，由(you)內冋(jiong)外插(cha)入孔位(wei)；波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)外側套(tao)上凹墊(dian)圈(quan)(quan)或凸墊(dian)圈(quan)(quan)，遇波(bo)使(shi)用(yong)(yong)凸墊(dian)圈(quan)(quan)，遇波(bo)峰(feng)使(shi)用(yong)(yong)凹墊(dian)圈(quan)(quan)墊(dian)圈(quan)(quan)外側旋(xuan)上螺(luo)(luo)(luo)母，在用(yong)(yong)套(tao)筒扳(ban)手(shou)預緊(jin)螺(luo)(luo)(luo)母，然后(hou)使(shi)用(yong)(yong)電動扳(ban)手(shou)緊(jin)固螺(luo)(luo)(luo)母兩塊板片(pian)(pian)(pian)洤全部(bu)安(an)裝完畢;波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)的(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)安(an)裝完畢后(hou)，需采用(yong)(yong)專用(yong)(yong)注膠槍于端(duan)部(bu)接合(he)處、緊(jin)回件(jian)連接的(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)孔空隙處涂抹中性硅酮耐候膠。緊(jin)接著(zhu)按(an)2#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)施工拼(pin)(pin)裝順序，拼(pin)(pin)裝好首圈(quan)(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)(guan)圖(tu)36偶數(shu)(shu)、奇(qi)數(shu)(shu)斷(duan)(duan)面(mian)交替(ti)拼(pin)(pin)裝順序

4、加強斷面拼裝

當(dang)波紋管涵直徑較大、填(tian)土高度較高時，必須設(she)置(zhi)加(jia)強管片，稱為加(jia)強圈(quan)”，加(jia)強斷面(mian)的管片安裝工序。
