大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)(she)拼裝支架(jia):搭設(she)(she)腳(jiao)手(shou)架(jia)根據波紋管(guan)(guan)(guan)的直(zhi)(zhi)徑(jing)提(ti)前(qian)確(que)定，采用管(guan)(guan)(guan)扣連接鋼(gang)管(guan)(guan)(guan)的方式搭設(she)(she)腳(jiao)手(shou)架(jia)，形式分(fen)A型和B型腳(jiao)手(shou)架(jia)長度(du)一(yi)般(ban)長25m、克(ke)0、6m、高為2d3(d為波紋管(guan)(guan)(guan)直(zhi)(zhi)徑(jing))，B型腳(jiao)手(shou)架(jia)一(yi)般(ban)克(ke)為25m高依(yi)據波紋管(guan)(guan)(guan)直(zhi)(zhi)徑(jing)大(da)小(xiao)拼裝接縫位置確(que)定尺寸(cun)。腳(jiao)手(shou)架(jia)按上述尺寸(cun)搭設(she)(she)便于施工(gong)、

2、拼(pin)(pin)裝類型與搭接方(fang)式：拼(pin)(pin)裝以中(zhong)心(xin)軸線(xian)為基準(zhun)，由中(zhong)心(xin)向兩端對稱進行安(an)裝，直至兩端。1斷面(mian)(奇(qi)數(shu)(shu)斷面(mian))、Ⅱ斷面(mian)(偶數(shu)(shu)斷面(mian))、加強斷面(mian)(偶數(shu)(shu)斷管管片(pian)）

3、波紋(wen)管(guan)(guan)拼裝：采(cai)用刻槽(cao)法施工的地基，安(an)裝吊車依(yi)據刻槽(cao)深度，依(yi)次安(an)裝底(di)部(bu)管(guan)(guan)片。底(di)部(bu)管(guan)(guan)片安(an)裝完成(cheng)后對剩余(yu)管(guan)(guan)片進行安(an)裝。管(guan)(guan)片安(an)裝同(tong)平基上(shang)的鋼波紋(wen)管(guan)(guan)施工。

首(shou)圈波紋(wen)管圈為(wei)奇數(shu)斷(duan)(duan)面(mian)(mian)(mian)，拼裝(zhuang)時(shi)應將(jiang)(jiang)管片(pian)立于地上安(an)裝(zhuang)，使(shi)(shi)用(yong)(yong)鐵鉤(gou)的一(yi)端勾(gou)住(zhu)I斷(duan)(duan)面(mian)(mian)(mian)片(pian)(1#管片(pian))波紋(wen)管管片(pian)螺(luo)(luo)絲囗，用(yong)(yong)12噸的吊車勾(gou)住(zhu)鐵鉤(gou)的另一(yi)端，將(jiang)(jiang)波紋(wen)管片(pian)立于墊(dian)層上，然后(hou)使(shi)(shi)用(yong)(yong)同樣(yang)的辦(ban)法將(jiang)(jiang)第二(er)片(pian)(6#管片(pian))波紋(wen)管管片(pian)按圖(tu)3、21斷(duan)(duan)面(mian)(mian)(mian)所(suo)示的搭接(jie)方式放(fang)置，使(shi)(shi)用(yong)(yong)撬棍(gun)將(jiang)(jiang)管片(pian)的螺(luo)(luo)栓(shuan)口(kou)對(dui)齊，將(jiang)(jiang)提前準備好的螺(luo)(luo)栓(shuan)螺(luo)(luo)紋(wen)部(bu)涂上渢滑(hua)劑(ji)，由內冋外插入孔(kong)位；波紋(wen)管外側套(tao)上凹墊(dian)圈或凸墊(dian)圈，遇波使(shi)(shi)用(yong)(yong)凸墊(dian)圈，遇波峰(feng)使(shi)(shi)用(yong)(yong)凹墊(dian)圈墊(dian)圈外側旋(xuan)上螺(luo)(luo)母(mu)(mu)，在用(yong)(yong)套(tao)筒扳手(shou)預緊螺(luo)(luo)母(mu)(mu)，然后(hou)使(shi)(shi)用(yong)(yong)電(dian)動扳手(shou)緊固螺(luo)(luo)母(mu)(mu)兩塊板(ban)片(pian)洤全(quan)部(bu)安(an)裝(zhuang)完畢;波紋(wen)管的螺(luo)(luo)栓(shuan)安(an)裝(zhuang)完畢后(hou)，需采用(yong)(yong)專用(yong)(yong)注膠槍于端部(bu)接(jie)合處、緊回件連接(jie)的螺(luo)(luo)栓(shuan)孔(kong)空隙處涂抹中性硅酮耐候膠。緊接(jie)著按2#管片(pian)、5#管片(pian)、3#管片(pian)、4#管片(pian)的施工拼裝(zhuang)順序，拼裝(zhuang)好首(shou)圈波紋(wen)管圖(tu)36偶數(shu)、奇數(shu)斷(duan)(duan)面(mian)(mian)(mian)交替拼裝(zhuang)順序

4、加強斷面拼裝

當(dang)波紋管(guan)(guan)涵直徑較(jiao)(jiao)大、填土高度(du)較(jiao)(jiao)高時，必須設置加強管(guan)(guan)片(pian)，稱為加強圈(quan)”，加強斷面的管(guan)(guan)片(pian)安裝工(gong)序(xu)。
