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(jiao)(jiao)手(shou)(shou)架(jia)(jia)根據波(bo)紋(wen)(wen)管的(de)直徑提前確(que)定(ding)(ding)，采用管扣(kou)連接鋼管的(de)方式搭設(she)腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)，形式分(fen)A型和(he)B型腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)長度一(yi)般(ban)長25m、克0、6m、高為(wei)2d3(d為(wei)波(bo)紋(wen)(wen)管直徑)，B型腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)一(yi)般(ban)克為(wei)25m高依據波(bo)紋(wen)(wen)管直徑大小(xiao)拼裝(zhuang)接縫位(wei)置確(que)定(ding)(ding)尺寸(cun)。腳(jiao)(jiao)手(shou)(shou)架(jia)(jia)按上述尺寸(cun)搭設(she)便于施工、

2、拼(pin)裝(zhuang)類型與搭接方式(shi)：拼(pin)裝(zhuang)以(yi)中心軸線為基準(zhun)，由中心向兩端對(dui)稱進行安裝(zhuang)，直(zhi)至兩端。1斷(duan)(duan)面(mian)(mian)(奇(qi)數(shu)(shu)斷(duan)(duan)面(mian)(mian))、Ⅱ斷(duan)(duan)面(mian)(mian)(偶(ou)數(shu)(shu)斷(duan)(duan)面(mian)(mian))、加強(qiang)斷(duan)(duan)面(mian)(mian)(偶(ou)數(shu)(shu)斷(duan)(duan)管(guan)管(guan)片）

3、波紋(wen)管拼裝(zhuang)：采用刻槽(cao)法施(shi)工(gong)的地基，安(an)裝(zhuang)吊車依(yi)據刻槽(cao)深(shen)度，依(yi)次安(an)裝(zhuang)底部(bu)管片。底部(bu)管片安(an)裝(zhuang)完成后對剩余(yu)管片進行安(an)裝(zhuang)。管片安(an)裝(zhuang)同(tong)平(ping)基上的鋼波紋(wen)管施(shi)工(gong)。

首圈(quan)(quan)(quan)波(bo)(bo)紋管(guan)(guan)圈(quan)(quan)(quan)為奇數斷(duan)(duan)面(mian)，拼裝(zhuang)時應將管(guan)(guan)片(pian)(pian)(pian)(pian)立(li)于地上(shang)(shang)安裝(zhuang)，使(shi)用(yong)鐵(tie)鉤(gou)的(de)一端(duan)(duan)勾住(zhu)I斷(duan)(duan)面(mian)片(pian)(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)絲囗，用(yong)12噸的(de)吊車勾住(zhu)鐵(tie)鉤(gou)的(de)另一端(duan)(duan)，將波(bo)(bo)紋管(guan)(guan)片(pian)(pian)(pian)(pian)立(li)于墊(dian)(dian)層上(shang)(shang)，然后使(shi)用(yong)同(tong)樣的(de)辦法(fa)將第二片(pian)(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian)(pian))波(bo)(bo)紋管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)按圖3、21斷(duan)(duan)面(mian)所(suo)示(shi)的(de)搭(da)接方式放置，使(shi)用(yong)撬棍(gun)將管(guan)(guan)片(pian)(pian)(pian)(pian)的(de)螺(luo)(luo)栓(shuan)口(kou)對齊，將提前準備好(hao)的(de)螺(luo)(luo)栓(shuan)螺(luo)(luo)紋部(bu)涂(tu)上(shang)(shang)渢滑劑，由(you)內(nei)冋(jiong)外插入(ru)孔位；波(bo)(bo)紋管(guan)(guan)外側套上(shang)(shang)凹(ao)墊(dian)(dian)圈(quan)(quan)(quan)或凸墊(dian)(dian)圈(quan)(quan)(quan)，遇波(bo)(bo)使(shi)用(yong)凸墊(dian)(dian)圈(quan)(quan)(quan)，遇波(bo)(bo)峰使(shi)用(yong)凹(ao)墊(dian)(dian)圈(quan)(quan)(quan)墊(dian)(dian)圈(quan)(quan)(quan)外側旋(xuan)上(shang)(shang)螺(luo)(luo)母(mu)，在用(yong)套筒扳(ban)手預緊螺(luo)(luo)母(mu)，然后使(shi)用(yong)電動扳(ban)手緊固螺(luo)(luo)母(mu)兩(liang)塊板(ban)片(pian)(pian)(pian)(pian)洤全部(bu)安裝(zhuang)完畢;波(bo)(bo)紋管(guan)(guan)的(de)螺(luo)(luo)栓(shuan)安裝(zhuang)完畢后，需采用(yong)專用(yong)注膠槍于端(duan)(duan)部(bu)接合處、緊回(hui)件連接的(de)螺(luo)(luo)栓(shuan)孔空隙處涂(tu)抹中性硅酮耐候(hou)膠。緊接著按2#管(guan)(guan)片(pian)(pian)(pian)(pian)、5#管(guan)(guan)片(pian)(pian)(pian)(pian)、3#管(guan)(guan)片(pian)(pian)(pian)(pian)、4#管(guan)(guan)片(pian)(pian)(pian)(pian)的(de)施工拼裝(zhuang)順序(xu)，拼裝(zhuang)好(hao)首圈(quan)(quan)(quan)波(bo)(bo)紋管(guan)(guan)圖36偶數、奇數斷(duan)(duan)面(mian)交替拼裝(zhuang)順序(xu)

4、加強斷面拼裝

當波紋管涵直徑較(jiao)大、填(tian)土高度(du)較(jiao)高時，必須設置加強(qiang)(qiang)管片，稱為加強(qiang)(qiang)圈(quan)”，加強(qiang)(qiang)斷面的(de)管片安裝工序。
