大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)(she)拼裝支(zhi)架(jia)(jia):搭(da)(da)設(she)(she)腳(jiao)手(shou)(shou)架(jia)(jia)根據波(bo)紋管(guan)的(de)直(zhi)徑(jing)提前確(que)定(ding)，采用管(guan)扣連接(jie)鋼管(guan)的(de)方(fang)式搭(da)(da)設(she)(she)腳(jiao)手(shou)(shou)架(jia)(jia)，形式分A型(xing)(xing)和B型(xing)(xing)腳(jiao)手(shou)(shou)架(jia)(jia)長度一(yi)般長25m、克(ke)0、6m、高為(wei)2d3(d為(wei)波(bo)紋管(guan)直(zhi)徑(jing))，B型(xing)(xing)腳(jiao)手(shou)(shou)架(jia)(jia)一(yi)般克(ke)為(wei)25m高依(yi)據波(bo)紋管(guan)直(zhi)徑(jing)大小拼裝接(jie)縫位置確(que)定(ding)尺寸(cun)。腳(jiao)手(shou)(shou)架(jia)(jia)按上(shang)述尺寸(cun)搭(da)(da)設(she)(she)便于(yu)施工、

2、拼(pin)裝類型與搭(da)接(jie)方式：拼(pin)裝以(yi)中(zhong)心軸(zhou)線為(wei)基準，由中(zhong)心向兩(liang)端(duan)對稱進行安裝，直至兩(liang)端(duan)。1斷(duan)(duan)面(mian)(mian)(奇數斷(duan)(duan)面(mian)(mian))、Ⅱ斷(duan)(duan)面(mian)(mian)(偶數斷(duan)(duan)面(mian)(mian))、加強(qiang)斷(duan)(duan)面(mian)(mian)(偶數斷(duan)(duan)管(guan)管(guan)片）

3、波(bo)(bo)紋管(guan)(guan)拼裝(zhuang)：采用刻(ke)槽法施工的(de)地基，安裝(zhuang)吊(diao)車依據(ju)刻(ke)槽深度(du)，依次安裝(zhuang)底部(bu)管(guan)(guan)片(pian)。底部(bu)管(guan)(guan)片(pian)安裝(zhuang)完成后對剩余管(guan)(guan)片(pian)進行安裝(zhuang)。管(guan)(guan)片(pian)安裝(zhuang)同平基上的(de)鋼波(bo)(bo)紋管(guan)(guan)施工。

首(shou)圈(quan)(quan)(quan)波(bo)(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)圈(quan)(quan)(quan)為(wei)奇(qi)數斷面(mian)，拼(pin)裝時(shi)應將(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)(guan)片立(li)于地上(shang)安裝，使(shi)(shi)用(yong)(yong)(yong)鐵鉤的(de)一端(duan)勾(gou)住(zhu)I斷面(mian)片(1#管(guan)(guan)(guan)(guan)(guan)(guan)片)波(bo)(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)片螺(luo)(luo)(luo)絲(si)囗，用(yong)(yong)(yong)12噸(dun)的(de)吊車勾(gou)住(zhu)鐵鉤的(de)另一端(duan)，將(jiang)(jiang)波(bo)(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)片立(li)于墊(dian)(dian)(dian)層上(shang)，然(ran)后(hou)使(shi)(shi)用(yong)(yong)(yong)同樣的(de)辦法將(jiang)(jiang)第二(er)片(6#管(guan)(guan)(guan)(guan)(guan)(guan)片)波(bo)(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)(guan)(guan)片按圖3、21斷面(mian)所(suo)示的(de)搭接(jie)方式放置，使(shi)(shi)用(yong)(yong)(yong)撬(qiao)棍將(jiang)(jiang)管(guan)(guan)(guan)(guan)(guan)(guan)片的(de)螺(luo)(luo)(luo)栓(shuan)口對齊，將(jiang)(jiang)提前準備好的(de)螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋部(bu)涂上(shang)渢滑(hua)劑(ji)，由內冋外插入孔(kong)位(wei)；波(bo)(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)外側套(tao)上(shang)凹墊(dian)(dian)(dian)圈(quan)(quan)(quan)或凸(tu)墊(dian)(dian)(dian)圈(quan)(quan)(quan)，遇波(bo)(bo)(bo)(bo)(bo)使(shi)(shi)用(yong)(yong)(yong)凸(tu)墊(dian)(dian)(dian)圈(quan)(quan)(quan)，遇波(bo)(bo)(bo)(bo)(bo)峰(feng)使(shi)(shi)用(yong)(yong)(yong)凹墊(dian)(dian)(dian)圈(quan)(quan)(quan)墊(dian)(dian)(dian)圈(quan)(quan)(quan)外側旋上(shang)螺(luo)(luo)(luo)母，在(zai)用(yong)(yong)(yong)套(tao)筒扳(ban)手(shou)預緊螺(luo)(luo)(luo)母，然(ran)后(hou)使(shi)(shi)用(yong)(yong)(yong)電動扳(ban)手(shou)緊固螺(luo)(luo)(luo)母兩(liang)塊(kuai)板片洤(quan)全部(bu)安裝完畢;波(bo)(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)的(de)螺(luo)(luo)(luo)栓(shuan)安裝完畢后(hou)，需(xu)采用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠槍(qiang)于端(duan)部(bu)接(jie)合處、緊回件連接(jie)的(de)螺(luo)(luo)(luo)栓(shuan)孔(kong)空隙(xi)處涂抹中(zhong)性硅酮耐候膠。緊接(jie)著按2#管(guan)(guan)(guan)(guan)(guan)(guan)片、5#管(guan)(guan)(guan)(guan)(guan)(guan)片、3#管(guan)(guan)(guan)(guan)(guan)(guan)片、4#管(guan)(guan)(guan)(guan)(guan)(guan)片的(de)施(shi)工拼(pin)裝順序(xu)(xu)，拼(pin)裝好首(shou)圈(quan)(quan)(quan)波(bo)(bo)(bo)(bo)(bo)紋管(guan)(guan)(guan)(guan)(guan)(guan)圖36偶數、奇(qi)數斷面(mian)交替拼(pin)裝順序(xu)(xu)

4、加強斷面拼裝

當波紋管(guan)涵直徑較(jiao)大(da)、填土高(gao)度較(jiao)高(gao)時，必須設置加強管(guan)片(pian)(pian)，稱(cheng)為加強圈”，加強斷面的管(guan)片(pian)(pian)安裝工(gong)序。
