大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝(zhuang)支架(jia):搭設(she)腳(jiao)(jiao)(jiao)手(shou)架(jia)根據(ju)波紋(wen)管(guan)(guan)的直徑提(ti)前(qian)確定，采(cai)用管(guan)(guan)扣連接鋼(gang)管(guan)(guan)的方式搭設(she)腳(jiao)(jiao)(jiao)手(shou)架(jia)，形式分A型(xing)和B型(xing)腳(jiao)(jiao)(jiao)手(shou)架(jia)長度一般長25m、克0、6m、高為(wei)2d3(d為(wei)波紋(wen)管(guan)(guan)直徑)，B型(xing)腳(jiao)(jiao)(jiao)手(shou)架(jia)一般克為(wei)25m高依據(ju)波紋(wen)管(guan)(guan)直徑大(da)小拼裝(zhuang)接縫位(wei)置確定尺寸。腳(jiao)(jiao)(jiao)手(shou)架(jia)按上述(shu)尺寸搭設(she)便于施工、

2、拼裝類型與搭接(jie)方式：拼裝以中心軸線為(wei)基準，由中心向兩端對稱進行安裝，直至兩端。1斷(duan)(duan)(duan)面(奇(qi)數(shu)(shu)斷(duan)(duan)(duan)面)、Ⅱ斷(duan)(duan)(duan)面(偶數(shu)(shu)斷(duan)(duan)(duan)面)、加(jia)強(qiang)斷(duan)(duan)(duan)面(偶數(shu)(shu)斷(duan)(duan)(duan)管管片）

3、波(bo)紋管(guan)拼裝(zhuang)(zhuang)：采用刻槽法施工(gong)的地基，安(an)裝(zhuang)(zhuang)吊(diao)車依據刻槽深度(du)，依次安(an)裝(zhuang)(zhuang)底部(bu)管(guan)片。底部(bu)管(guan)片安(an)裝(zhuang)(zhuang)完成(cheng)后對剩(sheng)余管(guan)片進行(xing)安(an)裝(zhuang)(zhuang)。管(guan)片安(an)裝(zhuang)(zhuang)同(tong)平基上的鋼(gang)波(bo)紋管(guan)施工(gong)。

首(shou)圈(quan)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)圈(quan)為(wei)奇(qi)數(shu)(shu)斷面(mian)(mian)，拼(pin)裝(zhuang)時應將管(guan)(guan)(guan)片(pian)(pian)立于(yu)地上(shang)安(an)(an)裝(zhuang)，使(shi)用(yong)鐵鉤(gou)的(de)(de)一端(duan)(duan)勾住I斷面(mian)(mian)片(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)螺(luo)絲囗，用(yong)12噸的(de)(de)吊車勾住鐵鉤(gou)的(de)(de)另一端(duan)(duan)，將波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)片(pian)(pian)立于(yu)墊(dian)(dian)(dian)層上(shang)，然后使(shi)用(yong)同樣的(de)(de)辦(ban)法(fa)將第二片(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)按(an)圖3、21斷面(mian)(mian)所示的(de)(de)搭接方式放置，使(shi)用(yong)撬棍將管(guan)(guan)(guan)片(pian)(pian)的(de)(de)螺(luo)栓(shuan)(shuan)(shuan)口(kou)對齊(qi)，將提(ti)前(qian)準(zhun)備好的(de)(de)螺(luo)栓(shuan)(shuan)(shuan)螺(luo)紋(wen)(wen)部涂(tu)上(shang)渢滑劑，由內冋外(wai)插入孔(kong)位；波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)外(wai)側(ce)(ce)套上(shang)凹墊(dian)(dian)(dian)圈(quan)或(huo)凸墊(dian)(dian)(dian)圈(quan)，遇波(bo)(bo)(bo)使(shi)用(yong)凸墊(dian)(dian)(dian)圈(quan)，遇波(bo)(bo)(bo)峰使(shi)用(yong)凹墊(dian)(dian)(dian)圈(quan)墊(dian)(dian)(dian)圈(quan)外(wai)側(ce)(ce)旋上(shang)螺(luo)母，在用(yong)套筒扳手預緊(jin)螺(luo)母，然后使(shi)用(yong)電動扳手緊(jin)固螺(luo)母兩塊(kuai)板片(pian)(pian)洤全部安(an)(an)裝(zhuang)完(wan)(wan)畢;波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)的(de)(de)螺(luo)栓(shuan)(shuan)(shuan)安(an)(an)裝(zhuang)完(wan)(wan)畢后，需采用(yong)專用(yong)注膠槍于(yu)端(duan)(duan)部接合(he)處、緊(jin)回件連接的(de)(de)螺(luo)栓(shuan)(shuan)(shuan)孔(kong)空(kong)隙處涂(tu)抹中性硅酮耐(nai)候膠。緊(jin)接著按(an)2#管(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)的(de)(de)施工拼(pin)裝(zhuang)順序，拼(pin)裝(zhuang)好首(shou)圈(quan)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)圖36偶數(shu)(shu)、奇(qi)數(shu)(shu)斷面(mian)(mian)交替拼(pin)裝(zhuang)順序

4、加強斷面拼裝

當波紋管涵直徑較(jiao)大、填土(tu)高度較(jiao)高時，必須設(she)置加(jia)強(qiang)管片，稱為(wei)加(jia)強(qiang)圈(quan)”，加(jia)強(qiang)斷面的(de)管片安(an)裝工序。
