大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)拼裝(zhuang)支架(jia)(jia):搭設(she)腳手架(jia)(jia)根據波紋管(guan)(guan)(guan)的直徑(jing)(jing)提前確定，采用(yong)管(guan)(guan)(guan)扣(kou)連接(jie)鋼管(guan)(guan)(guan)的方(fang)式(shi)搭設(she)腳手架(jia)(jia)，形式(shi)分A型(xing)(xing)和B型(xing)(xing)腳手架(jia)(jia)長度一(yi)(yi)般長25m、克0、6m、高為2d3(d為波紋管(guan)(guan)(guan)直徑(jing)(jing))，B型(xing)(xing)腳手架(jia)(jia)一(yi)(yi)般克為25m高依據波紋管(guan)(guan)(guan)直徑(jing)(jing)大(da)小拼裝(zhuang)接(jie)縫位置確定尺寸。腳手架(jia)(jia)按上述尺寸搭設(she)便于施工、

2、拼裝類型與搭接方式：拼裝以(yi)中心軸線為基準(zhun)，由中心向兩端對稱進行安裝，直至兩端。1斷(duan)面(奇數(shu)斷(duan)面)、Ⅱ斷(duan)面(偶數(shu)斷(duan)面)、加(jia)強斷(duan)面(偶數(shu)斷(duan)管管片）

3、波(bo)紋管(guan)(guan)拼(pin)裝(zhuang)：采用(yong)刻槽(cao)法施(shi)工的地基(ji)，安(an)裝(zhuang)吊車依(yi)據(ju)刻槽(cao)深度(du)，依(yi)次(ci)安(an)裝(zhuang)底部管(guan)(guan)片。底部管(guan)(guan)片安(an)裝(zhuang)完成后對剩余管(guan)(guan)片進行(xing)安(an)裝(zhuang)。管(guan)(guan)片安(an)裝(zhuang)同平(ping)基(ji)上的鋼波(bo)紋管(guan)(guan)施(shi)工。

首(shou)圈(quan)(quan)(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)圈(quan)(quan)(quan)為奇(qi)數(shu)斷面(mian)，拼(pin)裝(zhuang)時應將(jiang)(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立(li)于地上(shang)(shang)安(an)裝(zhuang)，使(shi)用(yong)鐵鉤的一端勾住(zhu)I斷面(mian)片(pian)(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)絲(si)囗，用(yong)12噸的吊車(che)勾住(zhu)鐵鉤的另(ling)一端，將(jiang)(jiang)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)立(li)于墊(dian)層(ceng)上(shang)(shang)，然后使(shi)用(yong)同樣的辦法將(jiang)(jiang)第(di)二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)按圖(tu)3、21斷面(mian)所(suo)示的搭(da)接方(fang)式放(fang)置，使(shi)用(yong)撬棍將(jiang)(jiang)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的螺(luo)(luo)栓(shuan)口(kou)對齊，將(jiang)(jiang)提前準備好(hao)的螺(luo)(luo)栓(shuan)螺(luo)(luo)紋(wen)部(bu)涂上(shang)(shang)渢滑(hua)劑，由(you)內冋外插(cha)入孔(kong)位；波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)外側套上(shang)(shang)凹(ao)墊(dian)圈(quan)(quan)(quan)或(huo)凸墊(dian)圈(quan)(quan)(quan)，遇波(bo)(bo)使(shi)用(yong)凸墊(dian)圈(quan)(quan)(quan)，遇波(bo)(bo)峰使(shi)用(yong)凹(ao)墊(dian)圈(quan)(quan)(quan)墊(dian)圈(quan)(quan)(quan)外側旋(xuan)上(shang)(shang)螺(luo)(luo)母(mu)，在用(yong)套筒扳(ban)(ban)手預緊(jin)螺(luo)(luo)母(mu)，然后使(shi)用(yong)電動(dong)扳(ban)(ban)手緊(jin)固螺(luo)(luo)母(mu)兩(liang)塊板(ban)片(pian)(pian)(pian)(pian)洤全(quan)部(bu)安(an)裝(zhuang)完畢;波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)的螺(luo)(luo)栓(shuan)安(an)裝(zhuang)完畢后，需采用(yong)專用(yong)注膠槍于端部(bu)接合處、緊(jin)回件連接的螺(luo)(luo)栓(shuan)孔(kong)空隙處涂抹中(zhong)性硅酮耐候膠。緊(jin)接著按2#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)(pian)的施工拼(pin)裝(zhuang)順序，拼(pin)裝(zhuang)好(hao)首(shou)圈(quan)(quan)(quan)波(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)圖(tu)36偶數(shu)、奇(qi)數(shu)斷面(mian)交替拼(pin)裝(zhuang)順序

4、加強斷面拼裝

當(dang)波紋管涵直徑較(jiao)(jiao)大(da)、填土高(gao)度較(jiao)(jiao)高(gao)時，必須設置加(jia)強管片(pian)，稱(cheng)為加(jia)強圈”，加(jia)強斷面(mian)的管片(pian)安(an)裝工序(xu)。
