大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)(she)拼裝支架(jia):搭(da)設(she)(she)腳(jiao)手(shou)(shou)架(jia)根據波(bo)紋管的直徑提前確定，采用管扣(kou)連接(jie)鋼管的方式(shi)搭(da)設(she)(she)腳(jiao)手(shou)(shou)架(jia)，形式(shi)分A型和B型腳(jiao)手(shou)(shou)架(jia)長度一般長25m、克(ke)0、6m、高為(wei)2d3(d為(wei)波(bo)紋管直徑)，B型腳(jiao)手(shou)(shou)架(jia)一般克(ke)為(wei)25m高依(yi)據波(bo)紋管直徑大小拼裝接(jie)縫(feng)位置(zhi)確定尺寸。腳(jiao)手(shou)(shou)架(jia)按上述(shu)尺寸搭(da)設(she)(she)便于施工、

2、拼裝(zhuang)類(lei)型與搭接方式(shi)：拼裝(zhuang)以中心軸線為基(ji)準，由中心向兩端對稱(cheng)進行安裝(zhuang)，直至兩端。1斷(duan)(duan)(duan)面(奇數斷(duan)(duan)(duan)面)、Ⅱ斷(duan)(duan)(duan)面(偶數斷(duan)(duan)(duan)面)、加強(qiang)斷(duan)(duan)(duan)面(偶數斷(duan)(duan)(duan)管管片）

3、波紋(wen)管拼裝(zhuang)(zhuang)：采用刻(ke)槽法施工的地基，安(an)(an)裝(zhuang)(zhuang)吊車依(yi)據刻(ke)槽深度，依(yi)次安(an)(an)裝(zhuang)(zhuang)底(di)部(bu)管片。底(di)部(bu)管片安(an)(an)裝(zhuang)(zhuang)完成后對剩余管片進行(xing)安(an)(an)裝(zhuang)(zhuang)。管片安(an)(an)裝(zhuang)(zhuang)同(tong)平基上(shang)的鋼波紋(wen)管施工。

首圈(quan)波(bo)(bo)(bo)紋管(guan)(guan)圈(quan)為奇數斷(duan)(duan)(duan)(duan)面，拼裝時應(ying)將(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)立(li)于(yu)(yu)地上(shang)(shang)(shang)安裝，使(shi)用(yong)(yong)(yong)鐵鉤的(de)(de)一端勾(gou)住I斷(duan)(duan)(duan)(duan)面片(pian)(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)(bo)紋管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)絲囗，用(yong)(yong)(yong)12噸的(de)(de)吊車(che)勾(gou)住鐵鉤的(de)(de)另一端，將(jiang)波(bo)(bo)(bo)紋管(guan)(guan)片(pian)(pian)(pian)(pian)立(li)于(yu)(yu)墊(dian)(dian)層上(shang)(shang)(shang)，然后使(shi)用(yong)(yong)(yong)同樣的(de)(de)辦法將(jiang)第二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)(bo)紋管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)按圖3、21斷(duan)(duan)(duan)(duan)面所(suo)示的(de)(de)搭接(jie)(jie)方式放置，使(shi)用(yong)(yong)(yong)撬棍將(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)的(de)(de)螺(luo)栓口(kou)對齊(qi)，將(jiang)提(ti)前準備好的(de)(de)螺(luo)栓螺(luo)紋部(bu)涂上(shang)(shang)(shang)渢滑劑，由(you)內冋外插(cha)入孔位；波(bo)(bo)(bo)紋管(guan)(guan)外側(ce)套上(shang)(shang)(shang)凹(ao)(ao)墊(dian)(dian)圈(quan)或凸墊(dian)(dian)圈(quan)，遇波(bo)(bo)(bo)使(shi)用(yong)(yong)(yong)凸墊(dian)(dian)圈(quan)，遇波(bo)(bo)(bo)峰使(shi)用(yong)(yong)(yong)凹(ao)(ao)墊(dian)(dian)圈(quan)墊(dian)(dian)圈(quan)外側(ce)旋上(shang)(shang)(shang)螺(luo)母(mu)，在(zai)用(yong)(yong)(yong)套筒扳手預緊(jin)(jin)螺(luo)母(mu)，然后使(shi)用(yong)(yong)(yong)電動扳手緊(jin)(jin)固螺(luo)母(mu)兩(liang)塊(kuai)板片(pian)(pian)(pian)(pian)洤全部(bu)安裝完(wan)畢;波(bo)(bo)(bo)紋管(guan)(guan)的(de)(de)螺(luo)栓安裝完(wan)畢后，需采(cai)用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠槍(qiang)于(yu)(yu)端部(bu)接(jie)(jie)合處、緊(jin)(jin)回件(jian)連接(jie)(jie)的(de)(de)螺(luo)栓孔空隙處涂抹(mo)中性硅(gui)酮耐候(hou)膠。緊(jin)(jin)接(jie)(jie)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)(de)施工拼裝順(shun)序，拼裝好首圈(quan)波(bo)(bo)(bo)紋管(guan)(guan)圖36偶數、奇數斷(duan)(duan)(duan)(duan)面交替拼裝順(shun)序

4、加強斷面拼裝

當波紋管涵(han)直徑(jing)較大、填土高(gao)度較高(gao)時，必須設置加(jia)(jia)強(qiang)管片，稱(cheng)為加(jia)(jia)強(qiang)圈(quan)”，加(jia)(jia)強(qiang)斷面的管片安(an)裝工序。
