大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)拼裝支架:搭(da)(da)設(she)腳(jiao)手架根據波(bo)紋管的直(zhi)(zhi)徑(jing)提前(qian)確定(ding)，采用管扣連接鋼管的方式(shi)搭(da)(da)設(she)腳(jiao)手架，形(xing)式(shi)分A型(xing)和B型(xing)腳(jiao)手架長(chang)度一(yi)般(ban)(ban)長(chang)25m、克0、6m、高為(wei)2d3(d為(wei)波(bo)紋管直(zhi)(zhi)徑(jing))，B型(xing)腳(jiao)手架一(yi)般(ban)(ban)克為(wei)25m高依據波(bo)紋管直(zhi)(zhi)徑(jing)大小拼裝接縫(feng)位置確定(ding)尺寸。腳(jiao)手架按(an)上述尺寸搭(da)(da)設(she)便于施工、

2、拼裝(zhuang)類型(xing)與搭接方式：拼裝(zhuang)以中心軸線(xian)為基(ji)準(zhun)，由中心向兩端(duan)對稱進行安裝(zhuang)，直至兩端(duan)。1斷(duan)面(mian)(奇(qi)數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶(ou)數斷(duan)面(mian))、加(jia)強(qiang)斷(duan)面(mian)(偶(ou)數斷(duan)管管片）

3、波(bo)紋管(guan)拼裝：采用刻槽法(fa)施工(gong)的地(di)基(ji)，安(an)(an)裝吊車依據刻槽深度，依次安(an)(an)裝底部管(guan)片。底部管(guan)片安(an)(an)裝完成后對剩余(yu)管(guan)片進行(xing)安(an)(an)裝。管(guan)片安(an)(an)裝同(tong)平基(ji)上的鋼波(bo)紋管(guan)施工(gong)。

首(shou)圈(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圈(quan)為奇(qi)數斷(duan)面，拼(pin)裝時應將(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于(yu)地上(shang)安裝，使(shi)用鐵(tie)鉤的(de)(de)(de)一端勾(gou)住I斷(duan)面片(pian)(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)螺(luo)(luo)絲囗(wei)，用12噸(dun)的(de)(de)(de)吊車勾(gou)住鐵(tie)鉤的(de)(de)(de)另一端，將(jiang)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立于(yu)墊層上(shang)，然后使(shi)用同樣的(de)(de)(de)辦法將(jiang)第二片(pian)(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)按(an)圖3、21斷(duan)面所示的(de)(de)(de)搭接方式放置，使(shi)用撬棍(gun)將(jiang)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)螺(luo)(luo)栓(shuan)口對齊，將(jiang)提(ti)前準(zhun)備(bei)好(hao)的(de)(de)(de)螺(luo)(luo)栓(shuan)螺(luo)(luo)紋(wen)(wen)部涂(tu)(tu)上(shang)渢滑劑(ji)，由內(nei)冋外(wai)插入孔位；波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)外(wai)側套(tao)上(shang)凹墊圈(quan)或凸(tu)墊圈(quan)，遇波(bo)使(shi)用凸(tu)墊圈(quan)，遇波(bo)峰使(shi)用凹墊圈(quan)墊圈(quan)外(wai)側旋上(shang)螺(luo)(luo)母，在用套(tao)筒扳(ban)手預緊(jin)螺(luo)(luo)母，然后使(shi)用電(dian)動扳(ban)手緊(jin)固螺(luo)(luo)母兩塊板片(pian)(pian)(pian)(pian)(pian)洤全部安裝完畢;波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)的(de)(de)(de)螺(luo)(luo)栓(shuan)安裝完畢后，需(xu)采用專用注膠槍于(yu)端部接合(he)處、緊(jin)回件連(lian)接的(de)(de)(de)螺(luo)(luo)栓(shuan)孔空隙(xi)處涂(tu)(tu)抹中性硅酮耐候膠。緊(jin)接著(zhu)按(an)2#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)施工拼(pin)裝順序，拼(pin)裝好(hao)首(shou)圈(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圖36偶數、奇(qi)數斷(duan)面交替拼(pin)裝順序

4、加強斷面拼裝

當(dang)波紋管(guan)涵直(zhi)徑較大、填土高度較高時，必須設置加強(qiang)管(guan)片，稱為加強(qiang)圈”，加強(qiang)斷面的管(guan)片安裝(zhuang)工序。
