大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設拼裝支(zhi)架(jia):搭(da)(da)設腳手(shou)架(jia)根據(ju)波(bo)紋管(guan)的直徑提前確定(ding)(ding)，采用管(guan)扣連(lian)接鋼管(guan)的方式搭(da)(da)設腳手(shou)架(jia)，形(xing)式分A型(xing)和B型(xing)腳手(shou)架(jia)長度一般長25m、克(ke)0、6m、高(gao)為(wei)2d3(d為(wei)波(bo)紋管(guan)直徑)，B型(xing)腳手(shou)架(jia)一般克(ke)為(wei)25m高(gao)依(yi)據(ju)波(bo)紋管(guan)直徑大小拼裝接縫(feng)位置確定(ding)(ding)尺(chi)寸(cun)。腳手(shou)架(jia)按上述尺(chi)寸(cun)搭(da)(da)設便于施(shi)工、

2、拼(pin)裝類型與搭接方(fang)式：拼(pin)裝以中心軸線為基準，由中心向兩端對稱進行安裝，直(zhi)至兩端。1斷面(mian)(奇數斷面(mian))、Ⅱ斷面(mian)(偶數斷面(mian))、加強(qiang)斷面(mian)(偶數斷管管片）

3、波紋管(guan)拼裝(zhuang)(zhuang)：采(cai)用(yong)刻槽(cao)法施工的地(di)基，安裝(zhuang)(zhuang)吊車(che)依據(ju)刻槽(cao)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(dui)剩(sheng)余(yu)管(guan)片進行安裝(zhuang)(zhuang)。管(guan)片安裝(zhuang)(zhuang)同平基上(shang)的鋼波紋管(guan)施工。

首圈(quan)波紋(wen)(wen)(wen)管(guan)(guan)(guan)圈(quan)為奇(qi)數(shu)斷(duan)面(mian)，拼(pin)裝(zhuang)(zhuang)(zhuang)時應將(jiang)管(guan)(guan)(guan)片(pian)(pian)立于地上(shang)(shang)安裝(zhuang)(zhuang)(zhuang)，使用(yong)(yong)(yong)鐵(tie)鉤(gou)(gou)的(de)一端(duan)勾(gou)住I斷(duan)面(mian)片(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian))波紋(wen)(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)(luo)絲囗，用(yong)(yong)(yong)12噸的(de)吊車(che)勾(gou)住鐵(tie)鉤(gou)(gou)的(de)另一端(duan)，將(jiang)波紋(wen)(wen)(wen)管(guan)(guan)(guan)片(pian)(pian)立于墊(dian)層(ceng)上(shang)(shang)，然后使用(yong)(yong)(yong)同(tong)樣的(de)辦法將(jiang)第(di)二片(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian))波紋(wen)(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)按圖3、21斷(duan)面(mian)所示的(de)搭接方(fang)式(shi)放置(zhi)，使用(yong)(yong)(yong)撬棍將(jiang)管(guan)(guan)(guan)片(pian)(pian)的(de)螺(luo)(luo)(luo)栓(shuan)口(kou)對齊，將(jiang)提前準備好(hao)的(de)螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋(wen)(wen)(wen)部(bu)涂上(shang)(shang)渢滑(hua)劑，由內冋外插入孔位；波紋(wen)(wen)(wen)管(guan)(guan)(guan)外側套(tao)上(shang)(shang)凹墊(dian)圈(quan)或(huo)凸(tu)墊(dian)圈(quan)，遇(yu)(yu)波使用(yong)(yong)(yong)凸(tu)墊(dian)圈(quan)，遇(yu)(yu)波峰使用(yong)(yong)(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外側旋上(shang)(shang)螺(luo)(luo)(luo)母，在用(yong)(yong)(yong)套(tao)筒扳手(shou)預緊螺(luo)(luo)(luo)母，然后使用(yong)(yong)(yong)電動扳手(shou)緊固螺(luo)(luo)(luo)母兩塊板片(pian)(pian)洤全部(bu)安裝(zhuang)(zhuang)(zhuang)完畢(bi);波紋(wen)(wen)(wen)管(guan)(guan)(guan)的(de)螺(luo)(luo)(luo)栓(shuan)安裝(zhuang)(zhuang)(zhuang)完畢(bi)后，需采用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠(jiao)槍(qiang)于端(duan)部(bu)接合處、緊回件(jian)連(lian)接的(de)螺(luo)(luo)(luo)栓(shuan)孔空隙處涂抹(mo)中性(xing)硅酮耐候膠(jiao)。緊接著按2#管(guan)(guan)(guan)片(pian)(pian)、5#管(guan)(guan)(guan)片(pian)(pian)、3#管(guan)(guan)(guan)片(pian)(pian)、4#管(guan)(guan)(guan)片(pian)(pian)的(de)施工拼(pin)裝(zhuang)(zhuang)(zhuang)順(shun)序(xu)，拼(pin)裝(zhuang)(zhuang)(zhuang)好(hao)首圈(quan)波紋(wen)(wen)(wen)管(guan)(guan)(guan)圖36偶數(shu)、奇(qi)數(shu)斷(duan)面(mian)交(jiao)替拼(pin)裝(zhuang)(zhuang)(zhuang)順(shun)序(xu)

4、加強斷面拼裝

當波紋管(guan)涵直徑(jing)較大(da)、填土高度較高時，必(bi)須設置加強管(guan)片，稱為加強圈(quan)”，加強斷面的管(guan)片安裝工序。
