大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼(pin)(pin)裝支架(jia):搭(da)設(she)腳(jiao)(jiao)手(shou)架(jia)根據波紋管的直徑(jing)提前(qian)確定(ding)，采用管扣(kou)連接鋼管的方式搭(da)設(she)腳(jiao)(jiao)手(shou)架(jia)，形式分(fen)A型和B型腳(jiao)(jiao)手(shou)架(jia)長(chang)度一般長(chang)25m、克(ke)0、6m、高為(wei)2d3(d為(wei)波紋管直徑(jing))，B型腳(jiao)(jiao)手(shou)架(jia)一般克(ke)為(wei)25m高依據波紋管直徑(jing)大小(xiao)拼(pin)(pin)裝接縫位(wei)置確定(ding)尺(chi)寸。腳(jiao)(jiao)手(shou)架(jia)按上述尺(chi)寸搭(da)設(she)便于施工、

2、拼裝類(lei)型與搭接方式：拼裝以中心軸線為基準，由中心向(xiang)兩端對稱進行安裝，直至(zhi)兩端。1斷面(mian)(mian)(奇數(shu)斷面(mian)(mian))、Ⅱ斷面(mian)(mian)(偶數(shu)斷面(mian)(mian))、加強斷面(mian)(mian)(偶數(shu)斷管(guan)管(guan)片(pian)）

3、波紋管(guan)拼裝：采用刻(ke)槽(cao)法施(shi)工的地基，安(an)裝吊車依(yi)據刻(ke)槽(cao)深度，依(yi)次(ci)安(an)裝底部管(guan)片(pian)。底部管(guan)片(pian)安(an)裝完成后對剩余管(guan)片(pian)進行安(an)裝。管(guan)片(pian)安(an)裝同平基上的鋼波紋管(guan)施(shi)工。

首圈(quan)波紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圈(quan)為奇數斷面，拼裝時應將管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于地(di)上(shang)(shang)安(an)裝，使用(yong)(yong)鐵鉤的(de)(de)一端(duan)勾(gou)(gou)住(zhu)I斷面片(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)(luo)絲囗，用(yong)(yong)12噸(dun)的(de)(de)吊車勾(gou)(gou)住(zhu)鐵鉤的(de)(de)另一端(duan)，將波紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于墊(dian)(dian)層上(shang)(shang)，然(ran)后(hou)使用(yong)(yong)同樣的(de)(de)辦法將第二(er)片(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)按圖3、21斷面所示的(de)(de)搭接(jie)(jie)方(fang)式放置，使用(yong)(yong)撬(qiao)棍(gun)將管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)螺(luo)(luo)(luo)栓口對齊，將提前準備好(hao)的(de)(de)螺(luo)(luo)(luo)栓螺(luo)(luo)(luo)紋(wen)(wen)(wen)(wen)部涂上(shang)(shang)渢(feng)滑劑(ji)，由內冋(jiong)外(wai)插入(ru)孔位；波紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)外(wai)側套上(shang)(shang)凹(ao)墊(dian)(dian)圈(quan)或凸(tu)墊(dian)(dian)圈(quan)，遇(yu)波使用(yong)(yong)凸(tu)墊(dian)(dian)圈(quan)，遇(yu)波峰使用(yong)(yong)凹(ao)墊(dian)(dian)圈(quan)墊(dian)(dian)圈(quan)外(wai)側旋上(shang)(shang)螺(luo)(luo)(luo)母(mu)，在用(yong)(yong)套筒扳手預緊螺(luo)(luo)(luo)母(mu)，然(ran)后(hou)使用(yong)(yong)電動扳手緊固(gu)螺(luo)(luo)(luo)母(mu)兩塊板片(pian)(pian)(pian)洤全部安(an)裝完畢(bi);波紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)的(de)(de)螺(luo)(luo)(luo)栓安(an)裝完畢(bi)后(hou)，需采用(yong)(yong)專用(yong)(yong)注(zhu)膠槍于端(duan)部接(jie)(jie)合處、緊回件(jian)連(lian)接(jie)(jie)的(de)(de)螺(luo)(luo)(luo)栓孔空(kong)隙處涂抹中性硅(gui)酮耐(nai)候膠。緊接(jie)(jie)著按2#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)施(shi)工拼裝順(shun)序，拼裝好(hao)首圈(quan)波紋(wen)(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圖36偶數、奇數斷面交替(ti)拼裝順(shun)序

4、加強斷面拼裝

當波紋管(guan)涵直徑較大、填土高(gao)度較高(gao)時(shi)，必須(xu)設置(zhi)加(jia)強管(guan)片(pian)，稱(cheng)為加(jia)強圈”，加(jia)強斷面(mian)的(de)管(guan)片(pian)安(an)裝工序。
