大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝支架(jia)(jia):搭(da)設(she)腳(jiao)(jiao)(jiao)手架(jia)(jia)根據波紋(wen)(wen)管的直(zhi)徑(jing)提前確定，采用管扣連接鋼管的方(fang)式(shi)搭(da)設(she)腳(jiao)(jiao)(jiao)手架(jia)(jia)，形式(shi)分(fen)A型和B型腳(jiao)(jiao)(jiao)手架(jia)(jia)長(chang)度一般長(chang)25m、克0、6m、高為2d3(d為波紋(wen)(wen)管直(zhi)徑(jing))，B型腳(jiao)(jiao)(jiao)手架(jia)(jia)一般克為25m高依據波紋(wen)(wen)管直(zhi)徑(jing)大(da)小拼裝接縫位(wei)置確定尺寸。腳(jiao)(jiao)(jiao)手架(jia)(jia)按上述尺寸搭(da)設(she)便于施工、

2、拼(pin)裝(zhuang)(zhuang)類型與搭(da)接方式：拼(pin)裝(zhuang)(zhuang)以中(zhong)心(xin)軸線為基準，由中(zhong)心(xin)向(xiang)兩端(duan)對(dui)稱(cheng)進行安裝(zhuang)(zhuang)，直至兩端(duan)。1斷(duan)(duan)(duan)(duan)面(mian)(奇(qi)數(shu)斷(duan)(duan)(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)(duan)(duan)面(mian)(偶(ou)數(shu)斷(duan)(duan)(duan)(duan)面(mian))、加(jia)強斷(duan)(duan)(duan)(duan)面(mian)(偶(ou)數(shu)斷(duan)(duan)(duan)(duan)管(guan)(guan)管(guan)(guan)片(pian)）

3、波(bo)紋管(guan)(guan)拼(pin)裝(zhuang)(zhuang)：采(cai)用刻槽法(fa)施工的地基，安(an)(an)裝(zhuang)(zhuang)吊車依(yi)(yi)據刻槽深度，依(yi)(yi)次安(an)(an)裝(zhuang)(zhuang)底(di)部(bu)管(guan)(guan)片。底(di)部(bu)管(guan)(guan)片安(an)(an)裝(zhuang)(zhuang)完成(cheng)后對剩余管(guan)(guan)片進(jin)行安(an)(an)裝(zhuang)(zhuang)。管(guan)(guan)片安(an)(an)裝(zhuang)(zhuang)同平基上(shang)的鋼(gang)波(bo)紋管(guan)(guan)施工。

首圈(quan)(quan)波(bo)(bo)紋(wen)管(guan)圈(quan)(quan)為(wei)奇數斷(duan)(duan)面(mian)，拼裝時應將管(guan)片(pian)(pian)立于地(di)上(shang)安裝，使(shi)(shi)用(yong)鐵鉤的(de)一端勾住I斷(duan)(duan)面(mian)片(pian)(pian)(1#管(guan)片(pian)(pian))波(bo)(bo)紋(wen)管(guan)管(guan)片(pian)(pian)螺(luo)絲囗，用(yong)12噸的(de)吊車勾住鐵鉤的(de)另一端，將波(bo)(bo)紋(wen)管(guan)片(pian)(pian)立于墊(dian)層上(shang)，然(ran)后(hou)使(shi)(shi)用(yong)同樣(yang)的(de)辦(ban)法(fa)將第二(er)片(pian)(pian)(6#管(guan)片(pian)(pian))波(bo)(bo)紋(wen)管(guan)管(guan)片(pian)(pian)按圖3、21斷(duan)(duan)面(mian)所(suo)示的(de)搭接(jie)(jie)方式放置，使(shi)(shi)用(yong)撬(qiao)棍將管(guan)片(pian)(pian)的(de)螺(luo)栓(shuan)口對齊，將提(ti)前準備好(hao)的(de)螺(luo)栓(shuan)螺(luo)紋(wen)部涂上(shang)渢滑劑(ji)，由內(nei)冋(jiong)外(wai)插入孔(kong)位；波(bo)(bo)紋(wen)管(guan)外(wai)側套上(shang)凹墊(dian)圈(quan)(quan)或凸(tu)墊(dian)圈(quan)(quan)，遇波(bo)(bo)使(shi)(shi)用(yong)凸(tu)墊(dian)圈(quan)(quan)，遇波(bo)(bo)峰使(shi)(shi)用(yong)凹墊(dian)圈(quan)(quan)墊(dian)圈(quan)(quan)外(wai)側旋上(shang)螺(luo)母，在用(yong)套筒扳手預緊螺(luo)母，然(ran)后(hou)使(shi)(shi)用(yong)電動扳手緊固螺(luo)母兩塊板片(pian)(pian)洤全部安裝完畢;波(bo)(bo)紋(wen)管(guan)的(de)螺(luo)栓(shuan)安裝完畢后(hou)，需采用(yong)專(zhuan)用(yong)注膠(jiao)槍于端部接(jie)(jie)合處(chu)(chu)、緊回件(jian)連接(jie)(jie)的(de)螺(luo)栓(shuan)孔(kong)空隙處(chu)(chu)涂抹(mo)中性硅酮耐候(hou)膠(jiao)。緊接(jie)(jie)著按2#管(guan)片(pian)(pian)、5#管(guan)片(pian)(pian)、3#管(guan)片(pian)(pian)、4#管(guan)片(pian)(pian)的(de)施工(gong)拼裝順序，拼裝好(hao)首圈(quan)(quan)波(bo)(bo)紋(wen)管(guan)圖36偶數、奇數斷(duan)(duan)面(mian)交替拼裝順序

4、加強斷面拼裝

當波紋管(guan)涵直徑較(jiao)大、填土(tu)高(gao)度較(jiao)高(gao)時(shi)，必須設置加強(qiang)管(guan)片，稱為加強(qiang)圈”，加強(qiang)斷面(mian)的管(guan)片安裝工(gong)序。
