大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝支(zhi)架(jia):搭(da)設(she)腳(jiao)(jiao)手架(jia)根據波(bo)紋管(guan)(guan)(guan)(guan)的直徑提前確定，采用管(guan)(guan)(guan)(guan)扣連接鋼管(guan)(guan)(guan)(guan)的方式搭(da)設(she)腳(jiao)(jiao)手架(jia)，形式分(fen)A型和B型腳(jiao)(jiao)手架(jia)長度(du)一般(ban)長25m、克(ke)0、6m、高為(wei)2d3(d為(wei)波(bo)紋管(guan)(guan)(guan)(guan)直徑)，B型腳(jiao)(jiao)手架(jia)一般(ban)克(ke)為(wei)25m高依據波(bo)紋管(guan)(guan)(guan)(guan)直徑大小拼裝接縫位置確定尺寸。腳(jiao)(jiao)手架(jia)按上述尺寸搭(da)設(she)便于施(shi)工、

2、拼裝類型與搭接(jie)方式：拼裝以中心軸線為基準(zhun)，由中心向兩端對稱進行安裝，直至兩端。1斷(duan)(duan)(duan)面(奇數(shu)斷(duan)(duan)(duan)面)、Ⅱ斷(duan)(duan)(duan)面(偶(ou)數(shu)斷(duan)(duan)(duan)面)、加強斷(duan)(duan)(duan)面(偶(ou)數(shu)斷(duan)(duan)(duan)管(guan)管(guan)片）

3、波紋管(guan)拼裝(zhuang)(zhuang)：采(cai)用刻(ke)(ke)槽(cao)法(fa)施(shi)工的(de)(de)地基，安裝(zhuang)(zhuang)吊車依據刻(ke)(ke)槽(cao)深(shen)度，依次(ci)安裝(zhuang)(zhuang)底(di)部(bu)(bu)管(guan)片。底(di)部(bu)(bu)管(guan)片安裝(zhuang)(zhuang)完成后對剩余(yu)管(guan)片進行安裝(zhuang)(zhuang)。管(guan)片安裝(zhuang)(zhuang)同平(ping)基上的(de)(de)鋼波紋管(guan)施(shi)工。

首圈波(bo)紋管(guan)(guan)圈為(wei)奇數斷(duan)(duan)面(mian)(mian)，拼(pin)裝(zhuang)(zhuang)(zhuang)時應(ying)將(jiang)管(guan)(guan)片(pian)(pian)立于地(di)上安(an)裝(zhuang)(zhuang)(zhuang)，使用(yong)(yong)鐵鉤的(de)(de)一端勾住I斷(duan)(duan)面(mian)(mian)片(pian)(pian)(1#管(guan)(guan)片(pian)(pian))波(bo)紋管(guan)(guan)管(guan)(guan)片(pian)(pian)螺(luo)(luo)(luo)絲(si)囗，用(yong)(yong)12噸(dun)的(de)(de)吊車(che)勾住鐵鉤的(de)(de)另一端，將(jiang)波(bo)紋管(guan)(guan)片(pian)(pian)立于墊層(ceng)上，然后使用(yong)(yong)同樣的(de)(de)辦法(fa)將(jiang)第(di)二片(pian)(pian)(6#管(guan)(guan)片(pian)(pian))波(bo)紋管(guan)(guan)管(guan)(guan)片(pian)(pian)按圖3、21斷(duan)(duan)面(mian)(mian)所示的(de)(de)搭(da)接方式放置，使用(yong)(yong)撬棍將(jiang)管(guan)(guan)片(pian)(pian)的(de)(de)螺(luo)(luo)(luo)栓(shuan)口對齊(qi)，將(jiang)提前準備好(hao)(hao)的(de)(de)螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋部(bu)涂(tu)上渢(feng)滑劑，由內冋外(wai)(wai)插入孔位；波(bo)紋管(guan)(guan)外(wai)(wai)側套上凹墊圈或凸(tu)墊圈，遇波(bo)使用(yong)(yong)凸(tu)墊圈，遇波(bo)峰使用(yong)(yong)凹墊圈墊圈外(wai)(wai)側旋上螺(luo)(luo)(luo)母，在用(yong)(yong)套筒扳(ban)手預緊(jin)螺(luo)(luo)(luo)母，然后使用(yong)(yong)電(dian)動扳(ban)手緊(jin)固螺(luo)(luo)(luo)母兩塊(kuai)板片(pian)(pian)洤全部(bu)安(an)裝(zhuang)(zhuang)(zhuang)完畢;波(bo)紋管(guan)(guan)的(de)(de)螺(luo)(luo)(luo)栓(shuan)安(an)裝(zhuang)(zhuang)(zhuang)完畢后，需(xu)采用(yong)(yong)專用(yong)(yong)注膠槍于端部(bu)接合處、緊(jin)回件連接的(de)(de)螺(luo)(luo)(luo)栓(shuan)孔空隙處涂(tu)抹中性硅酮耐候膠。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)施工(gong)拼(pin)裝(zhuang)(zhuang)(zhuang)順序，拼(pin)裝(zhuang)(zhuang)(zhuang)好(hao)(hao)首圈波(bo)紋管(guan)(guan)圖36偶數、奇數斷(duan)(duan)面(mian)(mian)交替拼(pin)裝(zhuang)(zhuang)(zhuang)順序

4、加強斷面拼裝

當波紋管涵(han)直徑較(jiao)大、填土高(gao)度較(jiao)高(gao)時(shi)，必須設置加強管片(pian)，稱為加強圈(quan)”，加強斷面的管片(pian)安裝工序(xu)。
