大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝支架(jia):搭(da)設(she)腳手(shou)架(jia)根據波紋(wen)管(guan)(guan)(guan)的直徑(jing)(jing)提前確(que)定，采(cai)用管(guan)(guan)(guan)扣連接(jie)鋼管(guan)(guan)(guan)的方式搭(da)設(she)腳手(shou)架(jia)，形式分A型(xing)和B型(xing)腳手(shou)架(jia)長度一(yi)般長25m、克0、6m、高(gao)為2d3(d為波紋(wen)管(guan)(guan)(guan)直徑(jing)(jing))，B型(xing)腳手(shou)架(jia)一(yi)般克為25m高(gao)依據波紋(wen)管(guan)(guan)(guan)直徑(jing)(jing)大(da)小拼裝接(jie)縫位置確(que)定尺寸(cun)。腳手(shou)架(jia)按(an)上述尺寸(cun)搭(da)設(she)便于施工、

2、拼裝(zhuang)類型與搭接方式：拼裝(zhuang)以中(zhong)心軸線為基準(zhun)，由中(zhong)心向兩(liang)端(duan)對稱進行(xing)安裝(zhuang)，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)紋管拼裝：采用刻槽(cao)法施工(gong)(gong)的(de)地基，安(an)(an)裝吊車(che)依(yi)據刻槽(cao)深(shen)度，依(yi)次安(an)(an)裝底(di)部管片(pian)。底(di)部管片(pian)安(an)(an)裝完成后對剩余管片(pian)進行(xing)安(an)(an)裝。管片(pian)安(an)(an)裝同(tong)平基上的(de)鋼波(bo)紋管施工(gong)(gong)。

首圈(quan)(quan)(quan)波(bo)(bo)紋(wen)(wen)(wen)管(guan)圈(quan)(quan)(quan)為奇數(shu)斷(duan)面，拼(pin)裝(zhuang)(zhuang)時應將管(guan)片(pian)(pian)立于(yu)地上(shang)安(an)裝(zhuang)(zhuang)，使(shi)用鐵鉤的(de)一(yi)端(duan)(duan)勾住(zhu)I斷(duan)面片(pian)(pian)(1#管(guan)片(pian)(pian))波(bo)(bo)紋(wen)(wen)(wen)管(guan)管(guan)片(pian)(pian)螺(luo)絲囗，用12噸的(de)吊車(che)勾住(zhu)鐵鉤的(de)另一(yi)端(duan)(duan)，將波(bo)(bo)紋(wen)(wen)(wen)管(guan)片(pian)(pian)立于(yu)墊(dian)(dian)(dian)層上(shang)，然(ran)(ran)后使(shi)用同樣的(de)辦法將第二片(pian)(pian)(6#管(guan)片(pian)(pian))波(bo)(bo)紋(wen)(wen)(wen)管(guan)管(guan)片(pian)(pian)按圖3、21斷(duan)面所示(shi)的(de)搭(da)接(jie)(jie)方式放(fang)置，使(shi)用撬棍將管(guan)片(pian)(pian)的(de)螺(luo)栓(shuan)口對齊，將提前準備好的(de)螺(luo)栓(shuan)螺(luo)紋(wen)(wen)(wen)部涂上(shang)渢滑(hua)劑，由(you)內(nei)冋外插(cha)入孔位；波(bo)(bo)紋(wen)(wen)(wen)管(guan)外側(ce)套(tao)上(shang)凹(ao)墊(dian)(dian)(dian)圈(quan)(quan)(quan)或(huo)凸(tu)墊(dian)(dian)(dian)圈(quan)(quan)(quan)，遇(yu)(yu)波(bo)(bo)使(shi)用凸(tu)墊(dian)(dian)(dian)圈(quan)(quan)(quan)，遇(yu)(yu)波(bo)(bo)峰使(shi)用凹(ao)墊(dian)(dian)(dian)圈(quan)(quan)(quan)墊(dian)(dian)(dian)圈(quan)(quan)(quan)外側(ce)旋上(shang)螺(luo)母，在用套(tao)筒扳(ban)手(shou)預(yu)緊(jin)(jin)螺(luo)母，然(ran)(ran)后使(shi)用電動扳(ban)手(shou)緊(jin)(jin)固螺(luo)母兩塊(kuai)板片(pian)(pian)洤全部安(an)裝(zhuang)(zhuang)完畢;波(bo)(bo)紋(wen)(wen)(wen)管(guan)的(de)螺(luo)栓(shuan)安(an)裝(zhuang)(zhuang)完畢后，需采用專用注膠槍于(yu)端(duan)(duan)部接(jie)(jie)合(he)處(chu)、緊(jin)(jin)回件連(lian)接(jie)(jie)的(de)螺(luo)栓(shuan)孔空(kong)隙處(chu)涂抹中性硅酮耐候膠。緊(jin)(jin)接(jie)(jie)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)施工(gong)拼(pin)裝(zhuang)(zhuang)順(shun)(shun)序(xu)，拼(pin)裝(zhuang)(zhuang)好首圈(quan)(quan)(quan)波(bo)(bo)紋(wen)(wen)(wen)管(guan)圖36偶數(shu)、奇數(shu)斷(duan)面交替拼(pin)裝(zhuang)(zhuang)順(shun)(shun)序(xu)

4、加強斷面拼裝

當波紋管(guan)涵直徑較大、填土高度(du)較高時(shi)，必須設置加強管(guan)片(pian)，稱為加強圈”，加強斷面的管(guan)片(pian)安裝工序。
