大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)(she)(she)拼裝支(zhi)架(jia):搭設(she)(she)(she)腳(jiao)手架(jia)根(gen)據波紋管的(de)直(zhi)徑(jing)提前確定，采(cai)用管扣連(lian)接鋼管的(de)方式搭設(she)(she)(she)腳(jiao)手架(jia)，形式分A型(xing)和(he)B型(xing)腳(jiao)手架(jia)長度(du)一般長25m、克0、6m、高為(wei)(wei)2d3(d為(wei)(wei)波紋管直(zhi)徑(jing))，B型(xing)腳(jiao)手架(jia)一般克為(wei)(wei)25m高依據波紋管直(zhi)徑(jing)大(da)小拼裝接縫位(wei)置確定尺寸(cun)。腳(jiao)手架(jia)按上(shang)述(shu)尺寸(cun)搭設(she)(she)(she)便(bian)于施工、

2、拼(pin)裝(zhuang)類型(xing)與搭接方式：拼(pin)裝(zhuang)以中(zhong)心軸線(xian)為基準，由中(zhong)心向兩(liang)端(duan)對稱進行安裝(zhuang)，直至兩(liang)端(duan)。1斷(duan)面(奇數(shu)斷(duan)面)、Ⅱ斷(duan)面(偶數(shu)斷(duan)面)、加強斷(duan)面(偶數(shu)斷(duan)管管片）

3、波紋管(guan)拼(pin)裝(zhuang)：采用刻槽(cao)法施工(gong)的地基，安(an)裝(zhuang)吊車依據刻槽(cao)深度，依次安(an)裝(zhuang)底(di)部管(guan)片。底(di)部管(guan)片安(an)裝(zhuang)完成后對(dui)剩余管(guan)片進行安(an)裝(zhuang)。管(guan)片安(an)裝(zhuang)同平基上的鋼波紋管(guan)施工(gong)。

首圈(quan)(quan)(quan)波(bo)紋(wen)(wen)管(guan)圈(quan)(quan)(quan)為奇數(shu)斷面(mian)，拼裝(zhuang)(zhuang)(zhuang)時應將(jiang)管(guan)片(pian)(pian)(pian)立于(yu)地上安裝(zhuang)(zhuang)(zhuang)，使(shi)(shi)用(yong)鐵(tie)鉤(gou)的(de)(de)一端(duan)勾住I斷面(mian)片(pian)(pian)(pian)(1#管(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)管(guan)片(pian)(pian)(pian)螺(luo)(luo)(luo)(luo)(luo)絲囗，用(yong)12噸的(de)(de)吊車勾住鐵(tie)鉤(gou)的(de)(de)另一端(duan)，將(jiang)波(bo)紋(wen)(wen)管(guan)片(pian)(pian)(pian)立于(yu)墊(dian)層上，然(ran)后(hou)(hou)使(shi)(shi)用(yong)同樣的(de)(de)辦(ban)法(fa)將(jiang)第(di)二(er)片(pian)(pian)(pian)(6#管(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)管(guan)管(guan)片(pian)(pian)(pian)按圖3、21斷面(mian)所(suo)示(shi)的(de)(de)搭接方式放置，使(shi)(shi)用(yong)撬棍將(jiang)管(guan)片(pian)(pian)(pian)的(de)(de)螺(luo)(luo)(luo)(luo)(luo)栓口對(dui)齊，將(jiang)提(ti)前準備好的(de)(de)螺(luo)(luo)(luo)(luo)(luo)栓螺(luo)(luo)(luo)(luo)(luo)紋(wen)(wen)部(bu)涂上渢滑劑，由內冋外插入孔位；波(bo)紋(wen)(wen)管(guan)外側套(tao)上凹墊(dian)圈(quan)(quan)(quan)或凸墊(dian)圈(quan)(quan)(quan)，遇(yu)波(bo)使(shi)(shi)用(yong)凸墊(dian)圈(quan)(quan)(quan)，遇(yu)波(bo)峰使(shi)(shi)用(yong)凹墊(dian)圈(quan)(quan)(quan)墊(dian)圈(quan)(quan)(quan)外側旋上螺(luo)(luo)(luo)(luo)(luo)母(mu)，在用(yong)套(tao)筒扳手預緊(jin)螺(luo)(luo)(luo)(luo)(luo)母(mu)，然(ran)后(hou)(hou)使(shi)(shi)用(yong)電(dian)動扳手緊(jin)固螺(luo)(luo)(luo)(luo)(luo)母(mu)兩(liang)塊板片(pian)(pian)(pian)洤全部(bu)安裝(zhuang)(zhuang)(zhuang)完畢;波(bo)紋(wen)(wen)管(guan)的(de)(de)螺(luo)(luo)(luo)(luo)(luo)栓安裝(zhuang)(zhuang)(zhuang)完畢后(hou)(hou)，需采用(yong)專用(yong)注(zhu)膠槍于(yu)端(duan)部(bu)接合處、緊(jin)回件(jian)連接的(de)(de)螺(luo)(luo)(luo)(luo)(luo)栓孔空隙處涂抹中性硅酮(tong)耐候膠。緊(jin)接著按2#管(guan)片(pian)(pian)(pian)、5#管(guan)片(pian)(pian)(pian)、3#管(guan)片(pian)(pian)(pian)、4#管(guan)片(pian)(pian)(pian)的(de)(de)施(shi)工拼裝(zhuang)(zhuang)(zhuang)順序，拼裝(zhuang)(zhuang)(zhuang)好首圈(quan)(quan)(quan)波(bo)紋(wen)(wen)管(guan)圖36偶數(shu)、奇數(shu)斷面(mian)交替(ti)拼裝(zhuang)(zhuang)(zhuang)順序

4、加強斷面拼裝

當波紋管涵直徑較大、填土高度(du)較高時(shi)，必須設置加(jia)強管片(pian)，稱為加(jia)強圈(quan)”，加(jia)強斷面(mian)的管片(pian)安裝工(gong)序。
