大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝支(zhi)架(jia):搭設腳(jiao)(jiao)(jiao)手(shou)架(jia)根據波紋(wen)管(guan)的直徑提前確(que)(que)定，采用(yong)管(guan)扣連接鋼管(guan)的方式(shi)搭設腳(jiao)(jiao)(jiao)手(shou)架(jia)，形式(shi)分A型(xing)(xing)和B型(xing)(xing)腳(jiao)(jiao)(jiao)手(shou)架(jia)長度一般(ban)長25m、克0、6m、高為2d3(d為波紋(wen)管(guan)直徑)，B型(xing)(xing)腳(jiao)(jiao)(jiao)手(shou)架(jia)一般(ban)克為25m高依據波紋(wen)管(guan)直徑大小拼裝接縫位(wei)置確(que)(que)定尺寸。腳(jiao)(jiao)(jiao)手(shou)架(jia)按上述尺寸搭設便于施工、

2、拼(pin)裝類型(xing)與(yu)搭接(jie)方式：拼(pin)裝以中心(xin)軸(zhou)線為基準，由(you)中心(xin)向(xiang)兩端對稱進(jin)行安裝，直至兩端。1斷(duan)(duan)(duan)面(奇數(shu)斷(duan)(duan)(duan)面)、Ⅱ斷(duan)(duan)(duan)面(偶數(shu)斷(duan)(duan)(duan)面)、加強斷(duan)(duan)(duan)面(偶數(shu)斷(duan)(duan)(duan)管(guan)管(guan)片）

3、波紋管(guan)(guan)拼裝(zhuang)(zhuang)：采用刻(ke)槽(cao)法施工的(de)地(di)基，安(an)裝(zhuang)(zhuang)吊車依據(ju)刻(ke)槽(cao)深度，依次安(an)裝(zhuang)(zhuang)底(di)部管(guan)(guan)片(pian)(pian)。底(di)部管(guan)(guan)片(pian)(pian)安(an)裝(zhuang)(zhuang)完成后對剩(sheng)余(yu)管(guan)(guan)片(pian)(pian)進(jin)行(xing)安(an)裝(zhuang)(zhuang)。管(guan)(guan)片(pian)(pian)安(an)裝(zhuang)(zhuang)同平基上的(de)鋼波紋管(guan)(guan)施工。

首圈(quan)波(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)圈(quan)為奇數(shu)斷面(mian)，拼裝(zhuang)時應將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立(li)于(yu)地上安(an)(an)裝(zhuang)，使用(yong)鐵鉤的(de)一端(duan)勾(gou)住I斷面(mian)片(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)絲囗，用(yong)12噸的(de)吊車勾(gou)住鐵鉤的(de)另(ling)一端(duan)，將(jiang)波(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立(li)于(yu)墊(dian)(dian)(dian)層(ceng)上，然后使用(yong)同樣(yang)的(de)辦法將(jiang)第二片(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)按(an)(an)圖3、21斷面(mian)所示的(de)搭接(jie)方式放置，使用(yong)撬棍將(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)螺(luo)栓(shuan)口(kou)對齊，將(jiang)提前(qian)準備好的(de)螺(luo)栓(shuan)螺(luo)紋(wen)(wen)(wen)(wen)部涂上渢滑劑，由(you)內冋外(wai)插入孔位；波(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)外(wai)側套上凹墊(dian)(dian)(dian)圈(quan)或凸墊(dian)(dian)(dian)圈(quan)，遇波(bo)使用(yong)凸墊(dian)(dian)(dian)圈(quan)，遇波(bo)峰使用(yong)凹墊(dian)(dian)(dian)圈(quan)墊(dian)(dian)(dian)圈(quan)外(wai)側旋上螺(luo)母(mu)，在用(yong)套筒扳手(shou)預緊(jin)(jin)螺(luo)母(mu)，然后使用(yong)電動扳手(shou)緊(jin)(jin)固螺(luo)母(mu)兩塊(kuai)板片(pian)(pian)(pian)洤全(quan)部安(an)(an)裝(zhuang)完畢;波(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)的(de)螺(luo)栓(shuan)安(an)(an)裝(zhuang)完畢后，需采用(yong)專用(yong)注膠槍(qiang)于(yu)端(duan)部接(jie)合處(chu)、緊(jin)(jin)回件連接(jie)的(de)螺(luo)栓(shuan)孔空(kong)隙處(chu)涂抹中性(xing)硅酮(tong)耐候膠。緊(jin)(jin)接(jie)著按(an)(an)2#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)施工拼裝(zhuang)順(shun)序，拼裝(zhuang)好首圈(quan)波(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)圖36偶數(shu)、奇數(shu)斷面(mian)交替拼裝(zhuang)順(shun)序

4、加強斷面拼裝

當波(bo)紋管涵直徑較(jiao)大(da)、填土(tu)高度較(jiao)高時，必(bi)須(xu)設置加強管片，稱為加強圈”，加強斷面的管片安(an)裝工序。
