大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)裝(zhuang)支架:搭設腳(jiao)手(shou)架根據波(bo)紋(wen)管(guan)的(de)直徑(jing)提前確定(ding)，采用管(guan)扣(kou)連接(jie)鋼(gang)管(guan)的(de)方(fang)式搭設腳(jiao)手(shou)架，形式分A型(xing)和B型(xing)腳(jiao)手(shou)架長(chang)度一(yi)(yi)般(ban)長(chang)25m、克0、6m、高(gao)為2d3(d為波(bo)紋(wen)管(guan)直徑(jing))，B型(xing)腳(jiao)手(shou)架一(yi)(yi)般(ban)克為25m高(gao)依據波(bo)紋(wen)管(guan)直徑(jing)大(da)小拼(pin)裝(zhuang)接(jie)縫(feng)位置確定(ding)尺寸。腳(jiao)手(shou)架按上述尺寸搭設便于施工、

2、拼裝(zhuang)類型與搭接方式：拼裝(zhuang)以中心(xin)軸線為基準，由中心(xin)向(xiang)兩(liang)端(duan)對稱進行(xing)安裝(zhuang)，直至(zhi)兩(liang)端(duan)。1斷(duan)面(奇數(shu)(shu)斷(duan)面)、Ⅱ斷(duan)面(偶數(shu)(shu)斷(duan)面)、加強斷(duan)面(偶數(shu)(shu)斷(duan)管管片(pian)）

3、波紋(wen)(wen)管拼裝：采用刻(ke)槽(cao)法施工的地基，安(an)裝吊車依據刻(ke)槽(cao)深度，依次安(an)裝底部管片。底部管片安(an)裝完成(cheng)后(hou)對剩(sheng)余管片進行安(an)裝。管片安(an)裝同(tong)平基上的鋼(gang)波紋(wen)(wen)管施工。

首圈(quan)(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)圈(quan)(quan)為奇數(shu)斷(duan)面(mian)，拼裝(zhuang)時應將(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)立于地上(shang)(shang)安(an)裝(zhuang)，使(shi)(shi)用鐵鉤的(de)一端勾住I斷(duan)面(mian)片(pian)(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)絲(si)囗，用12噸的(de)吊車勾住鐵鉤的(de)另一端，將(jiang)波(bo)紋(wen)(wen)(wen)管(guan)(guan)片(pian)(pian)(pian)(pian)立于墊層上(shang)(shang)，然(ran)后使(shi)(shi)用同樣的(de)辦(ban)法(fa)將(jiang)第(di)二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)按圖3、21斷(duan)面(mian)所(suo)示的(de)搭接方式放置，使(shi)(shi)用撬(qiao)棍將(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)的(de)螺(luo)(luo)栓口(kou)對齊，將(jiang)提前準備(bei)好的(de)螺(luo)(luo)栓螺(luo)(luo)紋(wen)(wen)(wen)部(bu)涂上(shang)(shang)渢滑(hua)劑，由內冋外插入孔位；波(bo)紋(wen)(wen)(wen)管(guan)(guan)外側套上(shang)(shang)凹墊圈(quan)(quan)或(huo)凸墊圈(quan)(quan)，遇(yu)波(bo)使(shi)(shi)用凸墊圈(quan)(quan)，遇(yu)波(bo)峰使(shi)(shi)用凹墊圈(quan)(quan)墊圈(quan)(quan)外側旋上(shang)(shang)螺(luo)(luo)母(mu)(mu)，在用套筒扳手預(yu)緊(jin)螺(luo)(luo)母(mu)(mu)，然(ran)后使(shi)(shi)用電動扳手緊(jin)固螺(luo)(luo)母(mu)(mu)兩塊(kuai)板片(pian)(pian)(pian)(pian)洤全部(bu)安(an)裝(zhuang)完畢;波(bo)紋(wen)(wen)(wen)管(guan)(guan)的(de)螺(luo)(luo)栓安(an)裝(zhuang)完畢后，需采用專(zhuan)用注膠槍于端部(bu)接合處、緊(jin)回件(jian)連接的(de)螺(luo)(luo)栓孔空隙處涂抹中(zhong)性硅酮耐(nai)候膠。緊(jin)接著按2#管(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)片(pian)(pian)(pian)(pian)的(de)施工(gong)拼裝(zhuang)順(shun)序，拼裝(zhuang)好首圈(quan)(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)圖36偶數(shu)、奇數(shu)斷(duan)面(mian)交替拼裝(zhuang)順(shun)序

4、加強斷面拼裝

當波(bo)紋管(guan)涵直徑較大、填土(tu)高度較高時(shi)，必須設置(zhi)加強管(guan)片，稱為加強圈(quan)”，加強斷面的管(guan)片安裝(zhuang)工序。
