大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼裝(zhuang)支架:搭(da)設腳(jiao)手架根據波紋管的直(zhi)徑(jing)提前確定，采用管扣連接鋼管的方(fang)式(shi)搭(da)設腳(jiao)手架，形式(shi)分A型(xing)和B型(xing)腳(jiao)手架長度一(yi)(yi)般長25m、克0、6m、高為2d3(d為波紋管直(zhi)徑(jing))，B型(xing)腳(jiao)手架一(yi)(yi)般克為25m高依據波紋管直(zhi)徑(jing)大小(xiao)拼裝(zhuang)接縫位置確定尺寸(cun)。腳(jiao)手架按上述(shu)尺寸(cun)搭(da)設便于(yu)施(shi)工、

2、拼裝類型與搭接方式：拼裝以(yi)中(zhong)心軸線為基準，由中(zhong)心向(xiang)兩端對(dui)稱進行安裝，直至兩端。1斷(duan)(duan)面(mian)(奇數斷(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)面(mian)(偶(ou)數斷(duan)(duan)面(mian))、加強斷(duan)(duan)面(mian)(偶(ou)數斷(duan)(duan)管(guan)管(guan)片）

3、波紋管(guan)拼裝(zhuang)(zhuang)：采用刻(ke)槽(cao)法施工的(de)地基，安裝(zhuang)(zhuang)吊車依據刻(ke)槽(cao)深度，依次安裝(zhuang)(zhuang)底(di)部管(guan)片。底(di)部管(guan)片安裝(zhuang)(zhuang)完成(cheng)后對剩余管(guan)片進行安裝(zhuang)(zhuang)。管(guan)片安裝(zhuang)(zhuang)同平基上(shang)的(de)鋼波紋管(guan)施工。

首(shou)圈波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)圈為(wei)奇(qi)數斷面，拼(pin)裝(zhuang)時(shi)應(ying)將(jiang)管(guan)(guan)(guan)片(pian)立于(yu)地上(shang)安(an)裝(zhuang)，使(shi)用(yong)(yong)(yong)(yong)(yong)(yong)(yong)鐵鉤的一端(duan)勾住(zhu)I斷面片(pian)(1#管(guan)(guan)(guan)片(pian))波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)螺(luo)(luo)(luo)絲(si)囗，用(yong)(yong)(yong)(yong)(yong)(yong)(yong)12噸的吊(diao)車勾住(zhu)鐵鉤的另一端(duan)，將(jiang)波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)片(pian)立于(yu)墊(dian)層(ceng)上(shang)，然后(hou)使(shi)用(yong)(yong)(yong)(yong)(yong)(yong)(yong)同(tong)樣的辦(ban)法將(jiang)第二片(pian)(6#管(guan)(guan)(guan)片(pian))波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)管(guan)(guan)(guan)片(pian)按圖3、21斷面所示的搭接方式放置(zhi)，使(shi)用(yong)(yong)(yong)(yong)(yong)(yong)(yong)撬棍將(jiang)管(guan)(guan)(guan)片(pian)的螺(luo)(luo)(luo)栓(shuan)口對齊(qi)，將(jiang)提前(qian)準備好的螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋(wen)(wen)部(bu)涂上(shang)渢滑劑，由內冋(jiong)外(wai)(wai)插入孔(kong)位；波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)外(wai)(wai)側套(tao)(tao)上(shang)凹墊(dian)圈或(huo)凸(tu)墊(dian)圈，遇波(bo)(bo)(bo)使(shi)用(yong)(yong)(yong)(yong)(yong)(yong)(yong)凸(tu)墊(dian)圈，遇波(bo)(bo)(bo)峰使(shi)用(yong)(yong)(yong)(yong)(yong)(yong)(yong)凹墊(dian)圈墊(dian)圈外(wai)(wai)側旋上(shang)螺(luo)(luo)(luo)母(mu)(mu)，在用(yong)(yong)(yong)(yong)(yong)(yong)(yong)套(tao)(tao)筒扳手預緊螺(luo)(luo)(luo)母(mu)(mu)，然后(hou)使(shi)用(yong)(yong)(yong)(yong)(yong)(yong)(yong)電動扳手緊固螺(luo)(luo)(luo)母(mu)(mu)兩塊板片(pian)洤(quan)全部(bu)安(an)裝(zhuang)完畢;波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)的螺(luo)(luo)(luo)栓(shuan)安(an)裝(zhuang)完畢后(hou)，需采用(yong)(yong)(yong)(yong)(yong)(yong)(yong)專(zhuan)用(yong)(yong)(yong)(yong)(yong)(yong)(yong)注膠槍于(yu)端(duan)部(bu)接合處、緊回件連接的螺(luo)(luo)(luo)栓(shuan)孔(kong)空隙處涂抹中性硅酮耐候膠。緊接著按2#管(guan)(guan)(guan)片(pian)、5#管(guan)(guan)(guan)片(pian)、3#管(guan)(guan)(guan)片(pian)、4#管(guan)(guan)(guan)片(pian)的施工(gong)拼(pin)裝(zhuang)順(shun)(shun)序，拼(pin)裝(zhuang)好首(shou)圈波(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)圖36偶數、奇(qi)數斷面交(jiao)替拼(pin)裝(zhuang)順(shun)(shun)序

4、加強斷面拼裝

當波紋管(guan)涵直(zhi)徑較(jiao)大(da)、填土高(gao)度較(jiao)高(gao)時，必須設置加(jia)(jia)強管(guan)片，稱為加(jia)(jia)強圈”，加(jia)(jia)強斷面的管(guan)片安裝工(gong)序。
