大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)裝支(zhi)架(jia)(jia):搭設腳(jiao)(jiao)(jiao)(jiao)手(shou)架(jia)(jia)根(gen)據(ju)波(bo)紋(wen)管的直徑(jing)(jing)提前確(que)(que)定，采用管扣連接(jie)鋼管的方式搭設腳(jiao)(jiao)(jiao)(jiao)手(shou)架(jia)(jia)，形式分A型和B型腳(jiao)(jiao)(jiao)(jiao)手(shou)架(jia)(jia)長度(du)一般(ban)長25m、克0、6m、高(gao)(gao)為2d3(d為波(bo)紋(wen)管直徑(jing)(jing))，B型腳(jiao)(jiao)(jiao)(jiao)手(shou)架(jia)(jia)一般(ban)克為25m高(gao)(gao)依據(ju)波(bo)紋(wen)管直徑(jing)(jing)大小拼(pin)裝接(jie)縫位置確(que)(que)定尺寸。腳(jiao)(jiao)(jiao)(jiao)手(shou)架(jia)(jia)按上述尺寸搭設便于施工、

2、拼裝(zhuang)類型(xing)與搭接(jie)方式：拼裝(zhuang)以中心軸線(xian)為基準，由(you)中心向兩(liang)端(duan)對(dui)稱(cheng)進行(xing)安裝(zhuang)，直至(zhi)兩(liang)端(duan)。1斷(duan)(duan)(duan)(duan)面(奇(qi)數斷(duan)(duan)(duan)(duan)面)、Ⅱ斷(duan)(duan)(duan)(duan)面(偶(ou)(ou)數斷(duan)(duan)(duan)(duan)面)、加強斷(duan)(duan)(duan)(duan)面(偶(ou)(ou)數斷(duan)(duan)(duan)(duan)管管片）

3、波(bo)紋管(guan)(guan)(guan)拼(pin)裝：采(cai)用刻(ke)槽法施(shi)工的地基(ji)，安(an)(an)裝吊車依(yi)據刻(ke)槽深度，依(yi)次(ci)安(an)(an)裝底(di)(di)部管(guan)(guan)(guan)片(pian)。底(di)(di)部管(guan)(guan)(guan)片(pian)安(an)(an)裝完(wan)成后對(dui)剩余管(guan)(guan)(guan)片(pian)進行安(an)(an)裝。管(guan)(guan)(guan)片(pian)安(an)(an)裝同平(ping)基(ji)上的鋼(gang)波(bo)紋管(guan)(guan)(guan)施(shi)工。

首圈(quan)波紋(wen)管(guan)(guan)(guan)圈(quan)為奇數(shu)(shu)斷面，拼(pin)裝(zhuang)(zhuang)時應(ying)將(jiang)(jiang)管(guan)(guan)(guan)片(pian)(pian)立于地(di)上安(an)裝(zhuang)(zhuang)，使用(yong)(yong)(yong)(yong)(yong)鐵(tie)鉤的(de)一端(duan)勾住(zhu)I斷面片(pian)(pian)(1#管(guan)(guan)(guan)片(pian)(pian))波紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)絲(si)囗，用(yong)(yong)(yong)(yong)(yong)12噸的(de)吊車勾住(zhu)鐵(tie)鉤的(de)另(ling)一端(duan)，將(jiang)(jiang)波紋(wen)管(guan)(guan)(guan)片(pian)(pian)立于墊層上，然后(hou)使用(yong)(yong)(yong)(yong)(yong)同樣的(de)辦(ban)法將(jiang)(jiang)第二(er)片(pian)(pian)(6#管(guan)(guan)(guan)片(pian)(pian))波紋(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)(pian)按圖(tu)(tu)3、21斷面所示的(de)搭接(jie)方式放置，使用(yong)(yong)(yong)(yong)(yong)撬(qiao)棍將(jiang)(jiang)管(guan)(guan)(guan)片(pian)(pian)的(de)螺(luo)(luo)栓口對(dui)齊，將(jiang)(jiang)提(ti)前(qian)準備好的(de)螺(luo)(luo)栓螺(luo)(luo)紋(wen)部(bu)涂上渢滑(hua)劑，由內冋外插入孔位；波紋(wen)管(guan)(guan)(guan)外側套(tao)(tao)上凹墊圈(quan)或凸墊圈(quan)，遇波使用(yong)(yong)(yong)(yong)(yong)凸墊圈(quan)，遇波峰使用(yong)(yong)(yong)(yong)(yong)凹墊圈(quan)墊圈(quan)外側旋上螺(luo)(luo)母，在用(yong)(yong)(yong)(yong)(yong)套(tao)(tao)筒扳(ban)手預緊(jin)(jin)螺(luo)(luo)母，然后(hou)使用(yong)(yong)(yong)(yong)(yong)電動(dong)扳(ban)手緊(jin)(jin)固螺(luo)(luo)母兩塊板片(pian)(pian)洤全部(bu)安(an)裝(zhuang)(zhuang)完(wan)畢(bi);波紋(wen)管(guan)(guan)(guan)的(de)螺(luo)(luo)栓安(an)裝(zhuang)(zhuang)完(wan)畢(bi)后(hou)，需采用(yong)(yong)(yong)(yong)(yong)專用(yong)(yong)(yong)(yong)(yong)注膠(jiao)槍于端(duan)部(bu)接(jie)合(he)處(chu)、緊(jin)(jin)回件連接(jie)的(de)螺(luo)(luo)栓孔空隙處(chu)涂抹中(zhong)性(xing)硅酮耐候膠(jiao)。緊(jin)(jin)接(jie)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)順序(xu)，拼(pin)裝(zhuang)(zhuang)好首圈(quan)波紋(wen)管(guan)(guan)(guan)圖(tu)(tu)36偶數(shu)(shu)、奇數(shu)(shu)斷面交替拼(pin)裝(zhuang)(zhuang)順序(xu)

4、加強斷面拼裝

當波紋管(guan)涵直徑較大、填土(tu)高度(du)較高時，必須(xu)設置加強(qiang)管(guan)片(pian)，稱(cheng)為(wei)加強(qiang)圈”，加強(qiang)斷(duan)面的管(guan)片(pian)安裝(zhuang)工序。
