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):搭設(she)腳(jiao)手(shou)架(jia)根據(ju)(ju)波紋管(guan)的(de)直徑提前確(que)定，采(cai)用管(guan)扣連(lian)接鋼(gang)管(guan)的(de)方式(shi)搭設(she)腳(jiao)手(shou)架(jia)，形式(shi)分(fen)A型和B型腳(jiao)手(shou)架(jia)長度一(yi)般(ban)長25m、克0、6m、高為2d3(d為波紋管(guan)直徑)，B型腳(jiao)手(shou)架(jia)一(yi)般(ban)克為25m高依據(ju)(ju)波紋管(guan)直徑大小拼裝(zhuang)接縫(feng)位置確(que)定尺寸。腳(jiao)手(shou)架(jia)按上述尺寸搭設(she)便(bian)于施工、

2、拼(pin)裝類型與(yu)搭接方式(shi)：拼(pin)裝以中心軸(zhou)線為基準，由中心向兩(liang)端對(dui)稱(cheng)進行安裝，直至兩(liang)端。1斷(duan)(duan)面(mian)(奇(qi)數(shu)(shu)斷(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)面(mian)(偶(ou)數(shu)(shu)斷(duan)(duan)面(mian))、加(jia)強(qiang)斷(duan)(duan)面(mian)(偶(ou)數(shu)(shu)斷(duan)(duan)管管片）

3、波(bo)(bo)紋(wen)管拼裝：采用刻槽(cao)法施工的地基，安(an)裝吊車依據刻槽(cao)深度，依次安(an)裝底部管片(pian)。底部管片(pian)安(an)裝完成(cheng)后對剩余管片(pian)進行安(an)裝。管片(pian)安(an)裝同平基上的鋼波(bo)(bo)紋(wen)管施工。

首(shou)圈(quan)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)圈(quan)為奇(qi)數斷(duan)面，拼裝時(shi)應(ying)將(jiang)(jiang)管(guan)片(pian)(pian)立于(yu)地上(shang)(shang)安裝，使(shi)用(yong)鐵(tie)鉤的(de)一(yi)端(duan)勾住I斷(duan)面片(pian)(pian)(1#管(guan)片(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)管(guan)片(pian)(pian)螺(luo)(luo)(luo)絲(si)囗(wei)，用(yong)12噸的(de)吊車勾住鐵(tie)鉤的(de)另一(yi)端(duan)，將(jiang)(jiang)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)片(pian)(pian)立于(yu)墊(dian)層(ceng)上(shang)(shang)，然(ran)后(hou)使(shi)用(yong)同樣的(de)辦法將(jiang)(jiang)第二片(pian)(pian)(6#管(guan)片(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)管(guan)片(pian)(pian)按(an)圖3、21斷(duan)面所示的(de)搭接(jie)方(fang)式放置，使(shi)用(yong)撬棍將(jiang)(jiang)管(guan)片(pian)(pian)的(de)螺(luo)(luo)(luo)栓(shuan)口對齊，將(jiang)(jiang)提(ti)前準備好(hao)的(de)螺(luo)(luo)(luo)栓(shuan)螺(luo)(luo)(luo)紋(wen)(wen)(wen)部(bu)涂(tu)上(shang)(shang)渢滑劑，由內(nei)冋外(wai)插(cha)入孔(kong)位；波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)外(wai)側(ce)套(tao)上(shang)(shang)凹墊(dian)圈(quan)或凸(tu)墊(dian)圈(quan)，遇(yu)波(bo)(bo)(bo)使(shi)用(yong)凸(tu)墊(dian)圈(quan)，遇(yu)波(bo)(bo)(bo)峰(feng)使(shi)用(yong)凹墊(dian)圈(quan)墊(dian)圈(quan)外(wai)側(ce)旋上(shang)(shang)螺(luo)(luo)(luo)母，在用(yong)套(tao)筒扳(ban)手(shou)預緊(jin)(jin)螺(luo)(luo)(luo)母，然(ran)后(hou)使(shi)用(yong)電(dian)動扳(ban)手(shou)緊(jin)(jin)固(gu)螺(luo)(luo)(luo)母兩塊板(ban)片(pian)(pian)洤(quan)全部(bu)安裝完(wan)畢;波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)的(de)螺(luo)(luo)(luo)栓(shuan)安裝完(wan)畢后(hou)，需采用(yong)專用(yong)注膠(jiao)(jiao)槍于(yu)端(duan)部(bu)接(jie)合處(chu)、緊(jin)(jin)回件(jian)連接(jie)的(de)螺(luo)(luo)(luo)栓(shuan)孔(kong)空(kong)隙(xi)處(chu)涂(tu)抹中性硅酮耐候膠(jiao)(jiao)。緊(jin)(jin)接(jie)著按(an)2#管(guan)片(pian)(pian)、5#管(guan)片(pian)(pian)、3#管(guan)片(pian)(pian)、4#管(guan)片(pian)(pian)的(de)施(shi)工拼裝順(shun)序，拼裝好(hao)首(shou)圈(quan)波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)圖36偶數、奇(qi)數斷(duan)面交(jiao)替拼裝順(shun)序

4、加強斷面拼裝

當波紋管涵直徑(jing)較大(da)、填土高度較高時，必須設置加強管片(pian)(pian)，稱為(wei)加強圈(quan)”，加強斷面的管片(pian)(pian)安裝(zhuang)工(gong)序。
