大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)裝支架(jia)(jia):搭設腳(jiao)(jiao)手架(jia)(jia)根據(ju)(ju)波紋(wen)(wen)管(guan)的直(zhi)徑提前確(que)定，采(cai)用管(guan)扣(kou)連接(jie)鋼(gang)管(guan)的方式(shi)搭設腳(jiao)(jiao)手架(jia)(jia)，形(xing)式(shi)分A型和B型腳(jiao)(jiao)手架(jia)(jia)長度(du)一般長25m、克(ke)0、6m、高為(wei)(wei)2d3(d為(wei)(wei)波紋(wen)(wen)管(guan)直(zhi)徑)，B型腳(jiao)(jiao)手架(jia)(jia)一般克(ke)為(wei)(wei)25m高依據(ju)(ju)波紋(wen)(wen)管(guan)直(zhi)徑大小拼(pin)裝接(jie)縫位置確(que)定尺(chi)寸。腳(jiao)(jiao)手架(jia)(jia)按(an)上述尺(chi)寸搭設便于施工、

2、拼裝類型(xing)與搭接(jie)方式：拼裝以中心軸線(xian)為(wei)基準，由中心向(xiang)兩(liang)(liang)端對稱進(jin)行安裝，直至(zhi)兩(liang)(liang)端。1斷面(mian)(奇數(shu)斷面(mian))、Ⅱ斷面(mian)(偶數(shu)斷面(mian))、加強斷面(mian)(偶數(shu)斷管管片）

3、波紋管(guan)拼裝(zhuang)(zhuang)：采(cai)用刻(ke)槽法施工的地基(ji)，安(an)(an)裝(zhuang)(zhuang)吊車依據刻(ke)槽深度，依次(ci)安(an)(an)裝(zhuang)(zhuang)底部管(guan)片(pian)。底部管(guan)片(pian)安(an)(an)裝(zhuang)(zhuang)完成后對剩余管(guan)片(pian)進行安(an)(an)裝(zhuang)(zhuang)。管(guan)片(pian)安(an)(an)裝(zhuang)(zhuang)同平(ping)基(ji)上的鋼波紋管(guan)施工。

首圈(quan)波紋管(guan)(guan)圈(quan)為奇數(shu)斷(duan)(duan)面(mian)(mian)，拼(pin)裝時應將(jiang)(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)(yu)地上(shang)安裝，使用(yong)(yong)鐵鉤(gou)的(de)(de)一端(duan)勾住(zhu)I斷(duan)(duan)面(mian)(mian)片(pian)(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian)(pian))波紋管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)絲囗，用(yong)(yong)12噸的(de)(de)吊車勾住(zhu)鐵鉤(gou)的(de)(de)另一端(duan)，將(jiang)(jiang)波紋管(guan)(guan)片(pian)(pian)(pian)(pian)立于(yu)(yu)墊(dian)層(ceng)上(shang)，然后(hou)(hou)使用(yong)(yong)同(tong)樣的(de)(de)辦(ban)法將(jiang)(jiang)第(di)二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian)(pian))波紋管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)按圖(tu)3、21斷(duan)(duan)面(mian)(mian)所示(shi)的(de)(de)搭接(jie)方式(shi)放置，使用(yong)(yong)撬(qiao)棍將(jiang)(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)螺(luo)(luo)栓(shuan)口(kou)對齊，將(jiang)(jiang)提(ti)前(qian)準備(bei)好的(de)(de)螺(luo)(luo)栓(shuan)螺(luo)(luo)紋部(bu)涂上(shang)渢滑劑，由內冋(jiong)外插入孔(kong)位；波紋管(guan)(guan)外側套(tao)上(shang)凹墊(dian)圈(quan)或凸墊(dian)圈(quan)，遇波使用(yong)(yong)凸墊(dian)圈(quan)，遇波峰使用(yong)(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外側旋上(shang)螺(luo)(luo)母，在用(yong)(yong)套(tao)筒扳手(shou)預(yu)緊(jin)螺(luo)(luo)母，然后(hou)(hou)使用(yong)(yong)電動扳手(shou)緊(jin)固螺(luo)(luo)母兩(liang)塊板片(pian)(pian)(pian)(pian)洤(quan)全部(bu)安裝完(wan)(wan)畢(bi);波紋管(guan)(guan)的(de)(de)螺(luo)(luo)栓(shuan)安裝完(wan)(wan)畢(bi)后(hou)(hou)，需(xu)采用(yong)(yong)專用(yong)(yong)注(zhu)膠(jiao)槍于(yu)(yu)端(duan)部(bu)接(jie)合處、緊(jin)回件連(lian)接(jie)的(de)(de)螺(luo)(luo)栓(shuan)孔(kong)空隙處涂抹中性硅酮(tong)耐候膠(jiao)。緊(jin)接(jie)著(zhu)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)(de)施工(gong)拼(pin)裝順序，拼(pin)裝好首圈(quan)波紋管(guan)(guan)圖(tu)36偶數(shu)、奇數(shu)斷(duan)(duan)面(mian)(mian)交替拼(pin)裝順序

4、加強斷面拼裝

當波紋管(guan)涵直徑較(jiao)大、填土高(gao)度較(jiao)高(gao)時，必(bi)須設置加強(qiang)管(guan)片(pian)，稱為加強(qiang)圈”，加強(qiang)斷面(mian)的(de)管(guan)片(pian)安裝工序。
