大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設(she)拼裝(zhuang)支架(jia):搭(da)(da)設(she)腳(jiao)手架(jia)根(gen)據波(bo)紋(wen)(wen)管(guan)的(de)直(zhi)(zhi)徑(jing)(jing)提前確定(ding)，采用管(guan)扣連接鋼(gang)管(guan)的(de)方(fang)式搭(da)(da)設(she)腳(jiao)手架(jia)，形式分(fen)A型和B型腳(jiao)手架(jia)長(chang)度(du)一(yi)般長(chang)25m、克0、6m、高為(wei)(wei)2d3(d為(wei)(wei)波(bo)紋(wen)(wen)管(guan)直(zhi)(zhi)徑(jing)(jing))，B型腳(jiao)手架(jia)一(yi)般克為(wei)(wei)25m高依據波(bo)紋(wen)(wen)管(guan)直(zhi)(zhi)徑(jing)(jing)大(da)小拼裝(zhuang)接縫(feng)位置確定(ding)尺(chi)寸。腳(jiao)手架(jia)按(an)上述(shu)尺(chi)寸搭(da)(da)設(she)便于施工、

2、拼(pin)(pin)裝類型(xing)與搭接方式：拼(pin)(pin)裝以中(zhong)心(xin)軸(zhou)線(xian)為基準(zhun)，由中(zhong)心(xin)向兩(liang)端(duan)對(dui)稱進行(xing)安裝，直至兩(liang)端(duan)。1斷面(奇(qi)數斷面)、Ⅱ斷面(偶數斷面)、加強斷面(偶數斷管管片）

3、波(bo)紋(wen)管(guan)(guan)(guan)(guan)拼裝(zhuang)：采用刻槽法(fa)施工的地基，安(an)(an)裝(zhuang)吊車依據(ju)刻槽深度，依次安(an)(an)裝(zhuang)底(di)部管(guan)(guan)(guan)(guan)片(pian)。底(di)部管(guan)(guan)(guan)(guan)片(pian)安(an)(an)裝(zhuang)完成后對剩余管(guan)(guan)(guan)(guan)片(pian)進行(xing)安(an)(an)裝(zhuang)。管(guan)(guan)(guan)(guan)片(pian)安(an)(an)裝(zhuang)同平基上的鋼(gang)波(bo)紋(wen)管(guan)(guan)(guan)(guan)施工。

首圈(quan)(quan)波(bo)(bo)(bo)紋(wen)(wen)管(guan)圈(quan)(quan)為奇數(shu)斷(duan)面，拼(pin)裝(zhuang)(zhuang)時(shi)應將管(guan)片(pian)(pian)立于(yu)地上(shang)(shang)安(an)裝(zhuang)(zhuang)，使(shi)用(yong)(yong)鐵鉤(gou)的(de)(de)(de)一端勾住(zhu)I斷(duan)面片(pian)(pian)(1#管(guan)片(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)管(guan)管(guan)片(pian)(pian)螺(luo)(luo)絲囗，用(yong)(yong)12噸的(de)(de)(de)吊車勾住(zhu)鐵鉤(gou)的(de)(de)(de)另一端，將波(bo)(bo)(bo)紋(wen)(wen)管(guan)片(pian)(pian)立于(yu)墊(dian)(dian)層上(shang)(shang)，然(ran)后(hou)使(shi)用(yong)(yong)同樣(yang)的(de)(de)(de)辦法將第二片(pian)(pian)(6#管(guan)片(pian)(pian))波(bo)(bo)(bo)紋(wen)(wen)管(guan)管(guan)片(pian)(pian)按圖(tu)3、21斷(duan)面所示的(de)(de)(de)搭接方式放置，使(shi)用(yong)(yong)撬棍將管(guan)片(pian)(pian)的(de)(de)(de)螺(luo)(luo)栓(shuan)口(kou)對(dui)齊，將提前(qian)準備好(hao)的(de)(de)(de)螺(luo)(luo)栓(shuan)螺(luo)(luo)紋(wen)(wen)部(bu)(bu)涂(tu)上(shang)(shang)渢滑劑(ji)，由內(nei)冋外(wai)(wai)插(cha)入孔位；波(bo)(bo)(bo)紋(wen)(wen)管(guan)外(wai)(wai)側套上(shang)(shang)凹墊(dian)(dian)圈(quan)(quan)或凸墊(dian)(dian)圈(quan)(quan)，遇波(bo)(bo)(bo)使(shi)用(yong)(yong)凸墊(dian)(dian)圈(quan)(quan)，遇波(bo)(bo)(bo)峰(feng)使(shi)用(yong)(yong)凹墊(dian)(dian)圈(quan)(quan)墊(dian)(dian)圈(quan)(quan)外(wai)(wai)側旋(xuan)上(shang)(shang)螺(luo)(luo)母，在用(yong)(yong)套筒(tong)扳(ban)手預緊(jin)(jin)螺(luo)(luo)母，然(ran)后(hou)使(shi)用(yong)(yong)電動扳(ban)手緊(jin)(jin)固螺(luo)(luo)母兩塊板(ban)片(pian)(pian)洤全部(bu)(bu)安(an)裝(zhuang)(zhuang)完(wan)畢;波(bo)(bo)(bo)紋(wen)(wen)管(guan)的(de)(de)(de)螺(luo)(luo)栓(shuan)安(an)裝(zhuang)(zhuang)完(wan)畢后(hou)，需采用(yong)(yong)專用(yong)(yong)注(zhu)膠槍于(yu)端部(bu)(bu)接合處、緊(jin)(jin)回件連接的(de)(de)(de)螺(luo)(luo)栓(shuan)孔空(kong)隙(xi)處涂(tu)抹中性(xing)硅酮耐候膠。緊(jin)(jin)接著按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)(de)(de)施工拼(pin)裝(zhuang)(zhuang)順(shun)序，拼(pin)裝(zhuang)(zhuang)好(hao)首圈(quan)(quan)波(bo)(bo)(bo)紋(wen)(wen)管(guan)圖(tu)36偶數(shu)、奇數(shu)斷(duan)面交替拼(pin)裝(zhuang)(zhuang)順(shun)序

4、加強斷面拼裝

當波紋管(guan)涵直徑(jing)較(jiao)大、填土高度較(jiao)高時，必須設(she)置加強(qiang)管(guan)片，稱為加強(qiang)圈”，加強(qiang)斷面的管(guan)片安裝工序(xu)。
