大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)(she)拼裝支架(jia):搭(da)設(she)(she)腳(jiao)手架(jia)根據波(bo)紋管(guan)的直(zhi)徑(jing)提前確(que)(que)定，采用管(guan)扣(kou)連(lian)接(jie)鋼管(guan)的方式搭(da)設(she)(she)腳(jiao)手架(jia)，形式分A型(xing)和B型(xing)腳(jiao)手架(jia)長度一(yi)般(ban)長25m、克0、6m、高(gao)為2d3(d為波(bo)紋管(guan)直(zhi)徑(jing))，B型(xing)腳(jiao)手架(jia)一(yi)般(ban)克為25m高(gao)依據波(bo)紋管(guan)直(zhi)徑(jing)大小拼裝接(jie)縫位(wei)置(zhi)確(que)(que)定尺寸。腳(jiao)手架(jia)按上(shang)述尺寸搭(da)設(she)(she)便于施工、

2、拼(pin)裝(zhuang)類型與(yu)搭接方式：拼(pin)裝(zhuang)以中心軸線為基(ji)準，由中心向兩(liang)端(duan)(duan)對稱進行安裝(zhuang)，直(zhi)至兩(liang)端(duan)(duan)。1斷面(mian)(奇數(shu)(shu)斷面(mian))、Ⅱ斷面(mian)(偶數(shu)(shu)斷面(mian))、加強斷面(mian)(偶數(shu)(shu)斷管管片）

3、波紋管拼裝(zhuang)(zhuang)：采用刻槽法施工(gong)的地基，安(an)裝(zhuang)(zhuang)吊車(che)依據刻槽深度，依次安(an)裝(zhuang)(zhuang)底部(bu)管片(pian)。底部(bu)管片(pian)安(an)裝(zhuang)(zhuang)完成后對剩余管片(pian)進行安(an)裝(zhuang)(zhuang)。管片(pian)安(an)裝(zhuang)(zhuang)同(tong)平基上的鋼波紋管施工(gong)。

首圈波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)圈為奇數斷(duan)面，拼(pin)裝(zhuang)時(shi)應(ying)將管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于(yu)地(di)上安裝(zhuang)，使(shi)用鐵(tie)鉤的(de)(de)(de)(de)一端勾(gou)住(zhu)I斷(duan)面片(pian)(pian)(pian)(1#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)絲囗，用12噸的(de)(de)(de)(de)吊車勾(gou)住(zhu)鐵(tie)鉤的(de)(de)(de)(de)另一端，將波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)立于(yu)墊(dian)層上，然后使(shi)用同樣的(de)(de)(de)(de)辦法將第二(er)片(pian)(pian)(pian)(6#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian))波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)按(an)圖(tu)(tu)3、21斷(duan)面所示的(de)(de)(de)(de)搭接(jie)(jie)方式放(fang)置，使(shi)用撬(qiao)棍將管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)(de)螺(luo)(luo)栓口對(dui)齊，將提前準(zhun)備好的(de)(de)(de)(de)螺(luo)(luo)栓螺(luo)(luo)紋(wen)部(bu)涂上渢滑劑，由(you)內冋(jiong)外(wai)插入(ru)孔(kong)位；波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)外(wai)側套(tao)上凹墊(dian)圈或凸墊(dian)圈，遇波(bo)(bo)(bo)使(shi)用凸墊(dian)圈，遇波(bo)(bo)(bo)峰使(shi)用凹墊(dian)圈墊(dian)圈外(wai)側旋上螺(luo)(luo)母(mu)，在用套(tao)筒扳(ban)手預(yu)緊(jin)螺(luo)(luo)母(mu)，然后使(shi)用電(dian)動扳(ban)手緊(jin)固螺(luo)(luo)母(mu)兩塊板片(pian)(pian)(pian)洤全(quan)部(bu)安裝(zhuang)完(wan)畢;波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)的(de)(de)(de)(de)螺(luo)(luo)栓安裝(zhuang)完(wan)畢后，需(xu)采用專用注膠(jiao)槍于(yu)端部(bu)接(jie)(jie)合處(chu)、緊(jin)回件(jian)連接(jie)(jie)的(de)(de)(de)(de)螺(luo)(luo)栓孔(kong)空隙處(chu)涂抹(mo)中性硅酮耐(nai)候膠(jiao)。緊(jin)接(jie)(jie)著按(an)2#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、5#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、3#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)、4#管(guan)(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)(de)施工(gong)拼(pin)裝(zhuang)順序(xu)，拼(pin)裝(zhuang)好首圈波(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)(guan)圖(tu)(tu)36偶數、奇數斷(duan)面交替拼(pin)裝(zhuang)順序(xu)

4、加強斷面拼裝

當波紋管(guan)涵(han)直(zhi)徑較(jiao)大(da)、填土高(gao)度較(jiao)高(gao)時，必須設(she)置加(jia)(jia)強(qiang)管(guan)片(pian)，稱為加(jia)(jia)強(qiang)圈”，加(jia)(jia)強(qiang)斷面的管(guan)片(pian)安裝工序。
