大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼裝支(zhi)架(jia)(jia):搭(da)設腳(jiao)手(shou)(shou)(shou)架(jia)(jia)根據波(bo)紋(wen)管的直(zhi)(zhi)徑(jing)提前確定(ding)，采用管扣連接鋼管的方式搭(da)設腳(jiao)手(shou)(shou)(shou)架(jia)(jia)，形式分A型(xing)和B型(xing)腳(jiao)手(shou)(shou)(shou)架(jia)(jia)長(chang)度一般長(chang)25m、克(ke)0、6m、高為(wei)(wei)2d3(d為(wei)(wei)波(bo)紋(wen)管直(zhi)(zhi)徑(jing))，B型(xing)腳(jiao)手(shou)(shou)(shou)架(jia)(jia)一般克(ke)為(wei)(wei)25m高依(yi)據波(bo)紋(wen)管直(zhi)(zhi)徑(jing)大小拼裝接縫(feng)位置確定(ding)尺(chi)寸(cun)。腳(jiao)手(shou)(shou)(shou)架(jia)(jia)按(an)上述尺(chi)寸(cun)搭(da)設便于施工、

2、拼裝類型(xing)與(yu)搭接方式：拼裝以(yi)中(zhong)心軸線為基準，由中(zhong)心向兩端(duan)對(dui)稱進行安裝，直至兩端(duan)。1斷面(mian)(mian)(mian)(奇(qi)數斷面(mian)(mian)(mian))、Ⅱ斷面(mian)(mian)(mian)(偶(ou)數斷面(mian)(mian)(mian))、加強斷面(mian)(mian)(mian)(偶(ou)數斷管管片）

3、波(bo)紋管(guan)拼裝(zhuang)(zhuang)：采(cai)用(yong)刻(ke)槽法施(shi)工的地基(ji)，安裝(zhuang)(zhuang)吊(diao)車依據刻(ke)槽深度，依次安裝(zhuang)(zhuang)底(di)部(bu)管(guan)片。底(di)部(bu)管(guan)片安裝(zhuang)(zhuang)完成后對剩(sheng)余管(guan)片進(jin)行(xing)安裝(zhuang)(zhuang)。管(guan)片安裝(zhuang)(zhuang)同平基(ji)上的鋼(gang)波(bo)紋管(guan)施(shi)工。

首(shou)圈(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)圈(quan)為奇(qi)數斷(duan)面(mian)，拼裝(zhuang)(zhuang)(zhuang)時應將(jiang)(jiang)管(guan)(guan)(guan)片(pian)立于(yu)地(di)上安(an)裝(zhuang)(zhuang)(zhuang)，使(shi)(shi)用鐵鉤的(de)(de)(de)(de)一端勾(gou)住I斷(duan)面(mian)片(pian)(1#管(guan)(guan)(guan)片(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)螺(luo)(luo)(luo)絲囗，用12噸的(de)(de)(de)(de)吊(diao)車(che)勾(gou)住鐵鉤的(de)(de)(de)(de)另一端，將(jiang)(jiang)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)片(pian)立于(yu)墊(dian)層上，然(ran)后使(shi)(shi)用同樣的(de)(de)(de)(de)辦法將(jiang)(jiang)第(di)二(er)片(pian)(6#管(guan)(guan)(guan)片(pian))波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)按圖3、21斷(duan)面(mian)所示的(de)(de)(de)(de)搭(da)接(jie)(jie)方式放(fang)置，使(shi)(shi)用撬棍將(jiang)(jiang)管(guan)(guan)(guan)片(pian)的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)口(kou)對(dui)齊，將(jiang)(jiang)提前準備(bei)好(hao)的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋(wen)(wen)(wen)部(bu)涂上渢滑(hua)劑，由內冋外插(cha)入孔(kong)位；波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)外側套上凹墊(dian)圈(quan)或(huo)凸墊(dian)圈(quan)，遇(yu)波(bo)使(shi)(shi)用凸墊(dian)圈(quan)，遇(yu)波(bo)峰使(shi)(shi)用凹墊(dian)圈(quan)墊(dian)圈(quan)外側旋上螺(luo)(luo)(luo)母(mu)(mu)(mu)，在(zai)用套筒扳(ban)手預(yu)緊(jin)(jin)螺(luo)(luo)(luo)母(mu)(mu)(mu)，然(ran)后使(shi)(shi)用電(dian)動扳(ban)手緊(jin)(jin)固螺(luo)(luo)(luo)母(mu)(mu)(mu)兩塊(kuai)板片(pian)洤(quan)全部(bu)安(an)裝(zhuang)(zhuang)(zhuang)完畢(bi);波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)安(an)裝(zhuang)(zhuang)(zhuang)完畢(bi)后，需采用專用注(zhu)膠(jiao)槍于(yu)端部(bu)接(jie)(jie)合處(chu)(chu)、緊(jin)(jin)回(hui)件連接(jie)(jie)的(de)(de)(de)(de)螺(luo)(luo)(luo)栓(shuan)孔(kong)空隙處(chu)(chu)涂抹中性硅酮耐候(hou)膠(jiao)。緊(jin)(jin)接(jie)(jie)著按2#管(guan)(guan)(guan)片(pian)、5#管(guan)(guan)(guan)片(pian)、3#管(guan)(guan)(guan)片(pian)、4#管(guan)(guan)(guan)片(pian)的(de)(de)(de)(de)施(shi)工(gong)拼裝(zhuang)(zhuang)(zhuang)順序，拼裝(zhuang)(zhuang)(zhuang)好(hao)首(shou)圈(quan)波(bo)紋(wen)(wen)(wen)管(guan)(guan)(guan)圖36偶數、奇(qi)數斷(duan)面(mian)交替拼裝(zhuang)(zhuang)(zhuang)順序

4、加強斷面拼裝

當波紋管涵直(zhi)徑較(jiao)大、填土高度較(jiao)高時，必(bi)須設(she)置加(jia)(jia)強管片，稱為加(jia)(jia)強圈”，加(jia)(jia)強斷(duan)面的管片安裝工序。
