大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼(pin)裝(zhuang)(zhuang)支架(jia)(jia):搭設(she)腳手(shou)架(jia)(jia)根據波紋(wen)(wen)管(guan)的直徑(jing)提前(qian)確定，采(cai)用管(guan)扣連接(jie)鋼管(guan)的方式(shi)(shi)搭設(she)腳手(shou)架(jia)(jia)，形式(shi)(shi)分A型(xing)和B型(xing)腳手(shou)架(jia)(jia)長度(du)一(yi)般(ban)(ban)長25m、克(ke)0、6m、高為2d3(d為波紋(wen)(wen)管(guan)直徑(jing))，B型(xing)腳手(shou)架(jia)(jia)一(yi)般(ban)(ban)克(ke)為25m高依據波紋(wen)(wen)管(guan)直徑(jing)大小拼(pin)裝(zhuang)(zhuang)接(jie)縫(feng)位置確定尺(chi)寸(cun)。腳手(shou)架(jia)(jia)按上述尺(chi)寸(cun)搭設(she)便于施工、

2、拼(pin)(pin)裝類型(xing)與搭接(jie)方式：拼(pin)(pin)裝以中(zhong)心軸線為基(ji)準(zhun)，由中(zhong)心向兩端對(dui)稱(cheng)進行(xing)安(an)裝，直至兩端。1斷(duan)(duan)(duan)(duan)面(奇數斷(duan)(duan)(duan)(duan)面)、Ⅱ斷(duan)(duan)(duan)(duan)面(偶數斷(duan)(duan)(duan)(duan)面)、加強斷(duan)(duan)(duan)(duan)面(偶數斷(duan)(duan)(duan)(duan)管(guan)管(guan)片）

3、波紋(wen)管(guan)(guan)拼(pin)裝：采用(yong)刻槽法施工的地基(ji)，安(an)(an)裝吊車依據刻槽深度，依次安(an)(an)裝底(di)部(bu)(bu)管(guan)(guan)片(pian)。底(di)部(bu)(bu)管(guan)(guan)片(pian)安(an)(an)裝完成后對剩余(yu)管(guan)(guan)片(pian)進行安(an)(an)裝。管(guan)(guan)片(pian)安(an)(an)裝同平基(ji)上(shang)的鋼波紋(wen)管(guan)(guan)施工。

首圈(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)圈(quan)為奇數斷面，拼裝(zhuang)時(shi)應將(jiang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)片立于(yu)地上(shang)安(an)裝(zhuang)，使用(yong)鐵(tie)鉤(gou)的(de)一(yi)端(duan)勾(gou)住I斷面片(1#管(guan)(guan)(guan)(guan)(guan)(guan)(guan)片)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)片螺(luo)絲囗，用(yong)12噸的(de)吊(diao)車勾(gou)住鐵(tie)鉤(gou)的(de)另一(yi)端(duan)，將(jiang)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)片立于(yu)墊(dian)(dian)層上(shang)，然后使用(yong)同樣(yang)的(de)辦法將(jiang)第二片(6#管(guan)(guan)(guan)(guan)(guan)(guan)(guan)片)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)片按圖3、21斷面所示的(de)搭接(jie)方式放(fang)置，使用(yong)撬棍將(jiang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)片的(de)螺(luo)栓(shuan)(shuan)口對齊，將(jiang)提前準備好(hao)(hao)的(de)螺(luo)栓(shuan)(shuan)螺(luo)紋(wen)部(bu)涂上(shang)渢滑劑(ji)，由(you)內(nei)冋外插入孔(kong)位(wei)；波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)外側套上(shang)凹墊(dian)(dian)圈(quan)或凸墊(dian)(dian)圈(quan)，遇(yu)波(bo)(bo)使用(yong)凸墊(dian)(dian)圈(quan)，遇(yu)波(bo)(bo)峰(feng)使用(yong)凹墊(dian)(dian)圈(quan)墊(dian)(dian)圈(quan)外側旋上(shang)螺(luo)母，在用(yong)套筒扳手(shou)預緊(jin)螺(luo)母，然后使用(yong)電(dian)動(dong)扳手(shou)緊(jin)固(gu)螺(luo)母兩塊板片洤(quan)全部(bu)安(an)裝(zhuang)完(wan)畢;波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)的(de)螺(luo)栓(shuan)(shuan)安(an)裝(zhuang)完(wan)畢后，需采(cai)用(yong)專用(yong)注膠(jiao)槍于(yu)端(duan)部(bu)接(jie)合處(chu)、緊(jin)回件連接(jie)的(de)螺(luo)栓(shuan)(shuan)孔(kong)空隙(xi)處(chu)涂抹中性硅酮耐候膠(jiao)。緊(jin)接(jie)著(zhu)按2#管(guan)(guan)(guan)(guan)(guan)(guan)(guan)片、5#管(guan)(guan)(guan)(guan)(guan)(guan)(guan)片、3#管(guan)(guan)(guan)(guan)(guan)(guan)(guan)片、4#管(guan)(guan)(guan)(guan)(guan)(guan)(guan)片的(de)施(shi)工拼裝(zhuang)順(shun)序，拼裝(zhuang)好(hao)(hao)首圈(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)圖36偶(ou)數、奇數斷面交替拼裝(zhuang)順(shun)序

4、加強斷面拼裝

當波紋管涵直徑(jing)較大(da)、填土高(gao)度較高(gao)時，必須設置加強(qiang)(qiang)管片(pian)(pian)，稱(cheng)為加強(qiang)(qiang)圈”，加強(qiang)(qiang)斷面的管片(pian)(pian)安裝工序(xu)。
