大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)裝支架(jia):搭設腳(jiao)(jiao)手(shou)(shou)架(jia)根據波(bo)(bo)紋(wen)管(guan)(guan)(guan)的(de)直徑(jing)(jing)提前確(que)定，采用管(guan)(guan)(guan)扣連接鋼管(guan)(guan)(guan)的(de)方式搭設腳(jiao)(jiao)手(shou)(shou)架(jia)，形式分A型(xing)和B型(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)長(chang)度一般長(chang)25m、克0、6m、高(gao)為2d3(d為波(bo)(bo)紋(wen)管(guan)(guan)(guan)直徑(jing)(jing))，B型(xing)腳(jiao)(jiao)手(shou)(shou)架(jia)一般克為25m高(gao)依據波(bo)(bo)紋(wen)管(guan)(guan)(guan)直徑(jing)(jing)大小拼(pin)裝接縫位(wei)置確(que)定尺寸(cun)。腳(jiao)(jiao)手(shou)(shou)架(jia)按上(shang)述尺寸(cun)搭設便于施(shi)工、

2、拼(pin)裝(zhuang)(zhuang)類型(xing)與搭接方式：拼(pin)裝(zhuang)(zhuang)以中心(xin)軸(zhou)線為基準，由中心(xin)向(xiang)兩端(duan)對稱進行安裝(zhuang)(zhuang)，直至兩端(duan)。1斷(duan)(duan)面(mian)(奇數斷(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)面(mian)(偶數斷(duan)(duan)面(mian))、加(jia)強(qiang)斷(duan)(duan)面(mian)(偶數斷(duan)(duan)管管片）

3、波紋管(guan)(guan)拼裝(zhuang)(zhuang)：采用(yong)刻槽法施(shi)工(gong)的地基(ji)(ji)，安(an)(an)裝(zhuang)(zhuang)吊(diao)車依據刻槽深度，依次(ci)安(an)(an)裝(zhuang)(zhuang)底(di)部管(guan)(guan)片(pian)。底(di)部管(guan)(guan)片(pian)安(an)(an)裝(zhuang)(zhuang)完成后對剩余管(guan)(guan)片(pian)進行安(an)(an)裝(zhuang)(zhuang)。管(guan)(guan)片(pian)安(an)(an)裝(zhuang)(zhuang)同平(ping)基(ji)(ji)上的鋼波紋管(guan)(guan)施(shi)工(gong)。

首圈波(bo)(bo)(bo)紋管(guan)圈為奇(qi)數斷面(mian)(mian)，拼裝(zhuang)(zhuang)時應將管(guan)片(pian)(pian)(pian)(pian)立于地上(shang)安裝(zhuang)(zhuang)，使(shi)(shi)(shi)用(yong)(yong)(yong)鐵鉤(gou)的(de)(de)(de)(de)一端(duan)(duan)勾(gou)住(zhu)I斷面(mian)(mian)片(pian)(pian)(pian)(pian)(1#管(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)(bo)紋管(guan)管(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)絲囗，用(yong)(yong)(yong)12噸(dun)的(de)(de)(de)(de)吊車勾(gou)住(zhu)鐵鉤(gou)的(de)(de)(de)(de)另一端(duan)(duan)，將波(bo)(bo)(bo)紋管(guan)片(pian)(pian)(pian)(pian)立于墊(dian)層上(shang)，然后(hou)使(shi)(shi)(shi)用(yong)(yong)(yong)同樣的(de)(de)(de)(de)辦法將第二(er)片(pian)(pian)(pian)(pian)(6#管(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)(bo)紋管(guan)管(guan)片(pian)(pian)(pian)(pian)按(an)(an)圖3、21斷面(mian)(mian)所示的(de)(de)(de)(de)搭接(jie)方式放置，使(shi)(shi)(shi)用(yong)(yong)(yong)撬棍將管(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)(de)螺(luo)(luo)栓口對齊(qi)，將提(ti)前準備好(hao)(hao)的(de)(de)(de)(de)螺(luo)(luo)栓螺(luo)(luo)紋部(bu)涂上(shang)渢(feng)滑劑，由內冋外插入孔(kong)位；波(bo)(bo)(bo)紋管(guan)外側套上(shang)凹(ao)墊(dian)圈或凸(tu)墊(dian)圈，遇(yu)波(bo)(bo)(bo)使(shi)(shi)(shi)用(yong)(yong)(yong)凸(tu)墊(dian)圈，遇(yu)波(bo)(bo)(bo)峰使(shi)(shi)(shi)用(yong)(yong)(yong)凹(ao)墊(dian)圈墊(dian)圈外側旋(xuan)上(shang)螺(luo)(luo)母，在用(yong)(yong)(yong)套筒扳(ban)手預(yu)緊(jin)螺(luo)(luo)母，然后(hou)使(shi)(shi)(shi)用(yong)(yong)(yong)電(dian)動扳(ban)手緊(jin)固螺(luo)(luo)母兩塊板片(pian)(pian)(pian)(pian)洤全部(bu)安裝(zhuang)(zhuang)完畢(bi);波(bo)(bo)(bo)紋管(guan)的(de)(de)(de)(de)螺(luo)(luo)栓安裝(zhuang)(zhuang)完畢(bi)后(hou)，需采用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠(jiao)槍于端(duan)(duan)部(bu)接(jie)合處、緊(jin)回件連(lian)接(jie)的(de)(de)(de)(de)螺(luo)(luo)栓孔(kong)空隙處涂抹中性硅酮耐候(hou)膠(jiao)。緊(jin)接(jie)著按(an)(an)2#管(guan)片(pian)(pian)(pian)(pian)、5#管(guan)片(pian)(pian)(pian)(pian)、3#管(guan)片(pian)(pian)(pian)(pian)、4#管(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)(de)施工拼裝(zhuang)(zhuang)順(shun)序，拼裝(zhuang)(zhuang)好(hao)(hao)首圈波(bo)(bo)(bo)紋管(guan)圖36偶(ou)數、奇(qi)數斷面(mian)(mian)交(jiao)替拼裝(zhuang)(zhuang)順(shun)序

4、加強斷面拼裝

當(dang)波紋管涵直徑較大、填土高度(du)較高時，必須(xu)設置加(jia)強管片，稱為加(jia)強圈(quan)”，加(jia)強斷面的管片安(an)裝(zhuang)工序。
