大直徑鋼波紋管拼裝方法你知道嗎?
1、搭(da)設(she)拼裝(zhuang)支(zhi)架(jia)(jia):搭(da)設(she)腳(jiao)手(shou)架(jia)(jia)根據波紋管(guan)(guan)的直徑提前確(que)定,采用管(guan)(guan)扣連(lian)接鋼(gang)管(guan)(guan)的方(fang)式搭(da)設(she)腳(jiao)手(shou)架(jia)(jia),形式分A型和B型腳(jiao)手(shou)架(jia)(jia)長(chang)(chang)度一般長(chang)(chang)25m、克(ke)0、6m、高為2d3(d為波紋管(guan)(guan)直徑),B型腳(jiao)手(shou)架(jia)(jia)一般克(ke)為25m高依據波紋管(guan)(guan)直徑大小(xiao)拼裝(zhuang)接縫位置確(que)定尺寸。腳(jiao)手(shou)架(jia)(jia)按(an)上述(shu)尺寸搭(da)設(she)便于(yu)施工、
2、拼(pin)裝類型與搭(da)接方式:拼(pin)裝以中(zhong)心軸線(xian)為基準,由中(zhong)心向兩端對稱進行安(an)裝,直(zhi)至兩端。1斷面(mian)(奇數斷面(mian))、Ⅱ斷面(mian)(偶(ou)數斷面(mian))、加強斷面(mian)(偶(ou)數斷管管片)
3、波(bo)紋管拼(pin)裝:采用刻槽(cao)法施工(gong)的地基,安裝吊車依據刻槽(cao)深度,依次(ci)安裝底(di)部管片。底(di)部管片安裝完成后對剩余管片進行安裝。管片安裝同平基上的鋼波(bo)紋管施工(gong)。
首圈(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圈(quan)為奇(qi)數斷(duan)(duan)(duan)面(mian),拼(pin)裝時應將管(guan)(guan)(guan)(guan)(guan)片(pian)立(li)于(yu)地上(shang)安(an)裝,使(shi)(shi)用(yong)鐵鉤的(de)(de)一端(duan)(duan)勾(gou)住I斷(duan)(duan)(duan)面(mian)片(pian)(1#管(guan)(guan)(guan)(guan)(guan)片(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)螺(luo)絲囗,用(yong)12噸的(de)(de)吊車勾(gou)住鐵鉤的(de)(de)另一端(duan)(duan),將波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)片(pian)立(li)于(yu)墊(dian)(dian)層上(shang),然(ran)后使(shi)(shi)用(yong)同樣的(de)(de)辦法將第二片(pian)(6#管(guan)(guan)(guan)(guan)(guan)片(pian))波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)片(pian)按圖3、21斷(duan)(duan)(duan)面(mian)所示的(de)(de)搭接(jie)方式放置,使(shi)(shi)用(yong)撬(qiao)棍將管(guan)(guan)(guan)(guan)(guan)片(pian)的(de)(de)螺(luo)栓(shuan)口(kou)對齊(qi),將提(ti)前準備好(hao)的(de)(de)螺(luo)栓(shuan)螺(luo)紋(wen)(wen)部(bu)涂上(shang)渢滑劑,由內冋(jiong)外插入孔(kong)位;波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)外側套(tao)上(shang)凹(ao)墊(dian)(dian)圈(quan)或凸墊(dian)(dian)圈(quan),遇(yu)波(bo)使(shi)(shi)用(yong)凸墊(dian)(dian)圈(quan),遇(yu)波(bo)峰使(shi)(shi)用(yong)凹(ao)墊(dian)(dian)圈(quan)墊(dian)(dian)圈(quan)外側旋上(shang)螺(luo)母,在用(yong)套(tao)筒扳(ban)(ban)手(shou)(shou)預緊螺(luo)母,然(ran)后使(shi)(shi)用(yong)電動扳(ban)(ban)手(shou)(shou)緊固螺(luo)母兩塊板片(pian)洤全(quan)部(bu)安(an)裝完畢;波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)的(de)(de)螺(luo)栓(shuan)安(an)裝完畢后,需采用(yong)專用(yong)注膠槍于(yu)端(duan)(duan)部(bu)接(jie)合處、緊回件(jian)連接(jie)的(de)(de)螺(luo)栓(shuan)孔(kong)空(kong)隙處涂抹(mo)中性硅酮耐候膠。緊接(jie)著按2#管(guan)(guan)(guan)(guan)(guan)片(pian)、5#管(guan)(guan)(guan)(guan)(guan)片(pian)、3#管(guan)(guan)(guan)(guan)(guan)片(pian)、4#管(guan)(guan)(guan)(guan)(guan)片(pian)的(de)(de)施工拼(pin)裝順(shun)序(xu),拼(pin)裝好(hao)首圈(quan)波(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)圖36偶數、奇(qi)數斷(duan)(duan)(duan)面(mian)交替拼(pin)裝順(shun)序(xu)
4、加強斷面拼裝
當波紋管涵(han)直徑較大、填土(tu)高(gao)度較高(gao)時,必須設置加強(qiang)管片,稱(cheng)為加強(qiang)圈”,加強(qiang)斷面的管片安(an)裝(zhuang)工(gong)序。
