大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼(pin)裝支架(jia):搭設(she)腳(jiao)手架(jia)根(gen)據波紋(wen)管的直徑提前確定，采用管扣連接(jie)鋼管的方(fang)式搭設(she)腳(jiao)手架(jia)，形式分A型(xing)和B型(xing)腳(jiao)手架(jia)長(chang)度一般(ban)長(chang)25m、克(ke)0、6m、高(gao)為2d3(d為波紋(wen)管直徑)，B型(xing)腳(jiao)手架(jia)一般(ban)克(ke)為25m高(gao)依(yi)據波紋(wen)管直徑大小拼(pin)裝接(jie)縫位(wei)置確定尺寸。腳(jiao)手架(jia)按上述尺寸搭設(she)便(bian)于施工(gong)、

2、拼裝(zhuang)類型與搭接方(fang)式：拼裝(zhuang)以中(zhong)心軸線(xian)為基(ji)準(zhun)，由中(zhong)心向(xiang)兩(liang)端對稱進行安裝(zhuang)，直至兩(liang)端。1斷(duan)(duan)面(奇數(shu)斷(duan)(duan)面)、Ⅱ斷(duan)(duan)面(偶數(shu)斷(duan)(duan)面)、加(jia)強(qiang)斷(duan)(duan)面(偶數(shu)斷(duan)(duan)管(guan)管(guan)片(pian)）

3、波紋(wen)管(guan)拼(pin)裝(zhuang)：采(cai)用(yong)刻(ke)槽(cao)法施工的地基，安裝(zhuang)吊車依據刻(ke)槽(cao)深度，依次安裝(zhuang)底部管(guan)片。底部管(guan)片安裝(zhuang)完成(cheng)后(hou)對(dui)剩余管(guan)片進行(xing)安裝(zhuang)。管(guan)片安裝(zhuang)同平基上的鋼波紋(wen)管(guan)施工。

鋼波紋管

首圈波(bo)紋(wen)(wen)管(guan)(guan)圈為(wei)奇數(shu)斷面(mian)，拼裝(zhuang)時應將(jiang)(jiang)管(guan)(guan)片(pian)(pian)立(li)于地(di)上(shang)安(an)裝(zhuang)，使(shi)(shi)用(yong)(yong)(yong)鐵(tie)鉤的(de)(de)一(yi)端勾住I斷面(mian)片(pian)(pian)(1#管(guan)(guan)片(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)螺(luo)絲囗，用(yong)(yong)(yong)12噸的(de)(de)吊車勾住鐵(tie)鉤的(de)(de)另一(yi)端，將(jiang)(jiang)波(bo)紋(wen)(wen)管(guan)(guan)片(pian)(pian)立(li)于墊層(ceng)上(shang)，然(ran)后使(shi)(shi)用(yong)(yong)(yong)同(tong)樣(yang)的(de)(de)辦法(fa)將(jiang)(jiang)第二片(pian)(pian)(6#管(guan)(guan)片(pian)(pian))波(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)按圖3、21斷面(mian)所示的(de)(de)搭接方式放置，使(shi)(shi)用(yong)(yong)(yong)撬(qiao)棍將(jiang)(jiang)管(guan)(guan)片(pian)(pian)的(de)(de)螺(luo)栓(shuan)口(kou)對齊，將(jiang)(jiang)提前(qian)準備好(hao)的(de)(de)螺(luo)栓(shuan)螺(luo)紋(wen)(wen)部(bu)涂上(shang)渢滑劑，由(you)內冋外插入孔位；波(bo)紋(wen)(wen)管(guan)(guan)外側(ce)套(tao)上(shang)凹(ao)墊圈或凸(tu)(tu)墊圈，遇波(bo)使(shi)(shi)用(yong)(yong)(yong)凸(tu)(tu)墊圈，遇波(bo)峰使(shi)(shi)用(yong)(yong)(yong)凹(ao)墊圈墊圈外側(ce)旋上(shang)螺(luo)母(mu)，在用(yong)(yong)(yong)套(tao)筒扳(ban)手預緊(jin)螺(luo)母(mu)，然(ran)后使(shi)(shi)用(yong)(yong)(yong)電動扳(ban)手緊(jin)固螺(luo)母(mu)兩塊板片(pian)(pian)洤全部(bu)安(an)裝(zhuang)完畢(bi);波(bo)紋(wen)(wen)管(guan)(guan)的(de)(de)螺(luo)栓(shuan)安(an)裝(zhuang)完畢(bi)后，需(xu)采用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠槍(qiang)于端部(bu)接合處(chu)(chu)、緊(jin)回件連接的(de)(de)螺(luo)栓(shuan)孔空(kong)隙(xi)處(chu)(chu)涂抹中性硅酮耐(nai)候膠。緊(jin)接著(zhu)按2#管(guan)(guan)片(pian)(pian)、5#管(guan)(guan)片(pian)(pian)、3#管(guan)(guan)片(pian)(pian)、4#管(guan)(guan)片(pian)(pian)的(de)(de)施(shi)工拼裝(zhuang)順序，拼裝(zhuang)好(hao)首圈波(bo)紋(wen)(wen)管(guan)(guan)圖36偶數(shu)、奇數(shu)斷面(mian)交替拼裝(zhuang)順序

4、加強斷面拼裝

當波紋管(guan)涵(han)直徑較(jiao)大、填土(tu)高度較(jiao)高時，必須設置加強管(guan)片(pian)，稱為加強圈”，加強斷面的管(guan)片(pian)安裝(zhuang)工序。
