大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設拼裝(zhuang)支(zhi)架(jia):搭(da)(da)設腳手(shou)(shou)架(jia)根據波紋管(guan)的直(zhi)徑提前確定，采用管(guan)扣連接鋼管(guan)的方式搭(da)(da)設腳手(shou)(shou)架(jia)，形式分A型和B型腳手(shou)(shou)架(jia)長度一(yi)般(ban)長25m、克0、6m、高(gao)為2d3(d為波紋管(guan)直(zhi)徑)，B型腳手(shou)(shou)架(jia)一(yi)般(ban)克為25m高(gao)依(yi)據波紋管(guan)直(zhi)徑大小(xiao)拼裝(zhuang)接縫位置確定尺寸。腳手(shou)(shou)架(jia)按上述尺寸搭(da)(da)設便(bian)于施(shi)工、

2、拼裝(zhuang)類型(xing)與搭接方式：拼裝(zhuang)以中(zhong)心(xin)軸線為基準，由中(zhong)心(xin)向兩端(duan)對(dui)稱進行安裝(zhuang)，直(zhi)至兩端(duan)。1斷面(mian)(mian)(mian)(奇數(shu)(shu)斷面(mian)(mian)(mian))、Ⅱ斷面(mian)(mian)(mian)(偶數(shu)(shu)斷面(mian)(mian)(mian))、加強斷面(mian)(mian)(mian)(偶數(shu)(shu)斷管管片）

3、波紋(wen)管(guan)拼(pin)裝(zhuang)：采用刻槽法施工(gong)(gong)的(de)地基，安(an)裝(zhuang)吊車依據(ju)刻槽深度(du)，依次安(an)裝(zhuang)底(di)部管(guan)片。底(di)部管(guan)片安(an)裝(zhuang)完成后對剩(sheng)余管(guan)片進行安(an)裝(zhuang)。管(guan)片安(an)裝(zhuang)同平基上(shang)的(de)鋼波紋(wen)管(guan)施工(gong)(gong)。

首圈(quan)(quan)(quan)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)圈(quan)(quan)(quan)為奇數(shu)斷面(mian)(mian)，拼裝(zhuang)(zhuang)(zhuang)時應將管(guan)(guan)片(pian)(pian)立于地(di)上(shang)(shang)安(an)裝(zhuang)(zhuang)(zhuang)，使(shi)(shi)用(yong)(yong)鐵(tie)(tie)鉤(gou)(gou)的(de)(de)(de)一(yi)端勾住(zhu)I斷面(mian)(mian)片(pian)(pian)(1#管(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)螺(luo)(luo)絲囗，用(yong)(yong)12噸的(de)(de)(de)吊車勾住(zhu)鐵(tie)(tie)鉤(gou)(gou)的(de)(de)(de)另一(yi)端，將波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)片(pian)(pian)立于墊(dian)層上(shang)(shang)，然(ran)后使(shi)(shi)用(yong)(yong)同樣的(de)(de)(de)辦(ban)法將第二片(pian)(pian)(6#管(guan)(guan)片(pian)(pian))波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)按(an)圖3、21斷面(mian)(mian)所示的(de)(de)(de)搭接方式放置(zhi)，使(shi)(shi)用(yong)(yong)撬棍將管(guan)(guan)片(pian)(pian)的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)口對齊，將提前準(zhun)備好(hao)的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)螺(luo)(luo)紋(wen)(wen)(wen)部(bu)涂(tu)上(shang)(shang)渢滑劑，由(you)內冋外(wai)(wai)插入孔位；波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)外(wai)(wai)側套(tao)(tao)上(shang)(shang)凹(ao)墊(dian)圈(quan)(quan)(quan)或凸(tu)墊(dian)圈(quan)(quan)(quan)，遇(yu)波(bo)(bo)使(shi)(shi)用(yong)(yong)凸(tu)墊(dian)圈(quan)(quan)(quan)，遇(yu)波(bo)(bo)峰使(shi)(shi)用(yong)(yong)凹(ao)墊(dian)圈(quan)(quan)(quan)墊(dian)圈(quan)(quan)(quan)外(wai)(wai)側旋上(shang)(shang)螺(luo)(luo)母(mu)，在用(yong)(yong)套(tao)(tao)筒扳手(shou)預緊(jin)螺(luo)(luo)母(mu)，然(ran)后使(shi)(shi)用(yong)(yong)電動(dong)扳手(shou)緊(jin)固螺(luo)(luo)母(mu)兩塊(kuai)板片(pian)(pian)洤全部(bu)安(an)裝(zhuang)(zhuang)(zhuang)完畢;波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)安(an)裝(zhuang)(zhuang)(zhuang)完畢后，需(xu)采用(yong)(yong)專(zhuan)用(yong)(yong)注膠槍于端部(bu)接合處(chu)、緊(jin)回件連(lian)接的(de)(de)(de)螺(luo)(luo)栓(shuan)(shuan)孔空隙處(chu)涂(tu)抹中性硅酮耐候膠。緊(jin)接著按(an)2#管(guan)(guan)片(pian)(pian)、5#管(guan)(guan)片(pian)(pian)、3#管(guan)(guan)片(pian)(pian)、4#管(guan)(guan)片(pian)(pian)的(de)(de)(de)施工拼裝(zhuang)(zhuang)(zhuang)順(shun)序，拼裝(zhuang)(zhuang)(zhuang)好(hao)首圈(quan)(quan)(quan)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)圖36偶數(shu)、奇數(shu)斷面(mian)(mian)交替拼裝(zhuang)(zhuang)(zhuang)順(shun)序

4、加強斷面拼裝

當波紋管涵直徑較大(da)、填土高度較高時，必須設(she)置加(jia)(jia)強(qiang)(qiang)管片，稱(cheng)為(wei)加(jia)(jia)強(qiang)(qiang)圈”，加(jia)(jia)強(qiang)(qiang)斷面的管片安裝工序。
