大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝支架(jia)(jia):搭設腳手(shou)(shou)架(jia)(jia)根據(ju)(ju)波(bo)紋(wen)管(guan)(guan)的直徑提前確定，采(cai)用管(guan)(guan)扣連接鋼(gang)管(guan)(guan)的方式搭設腳手(shou)(shou)架(jia)(jia)，形式分A型(xing)和(he)B型(xing)腳手(shou)(shou)架(jia)(jia)長(chang)度一般長(chang)25m、克0、6m、高為2d3(d為波(bo)紋(wen)管(guan)(guan)直徑)，B型(xing)腳手(shou)(shou)架(jia)(jia)一般克為25m高依據(ju)(ju)波(bo)紋(wen)管(guan)(guan)直徑大小拼裝接縫(feng)位置確定尺寸。腳手(shou)(shou)架(jia)(jia)按上述(shu)尺寸搭設便于施工(gong)、

2、拼(pin)裝(zhuang)類(lei)型與搭接(jie)方式：拼(pin)裝(zhuang)以中(zhong)心軸線為(wei)基(ji)準，由中(zhong)心向兩端(duan)對(dui)稱進行安裝(zhuang)，直至兩端(duan)。1斷面(mian)(奇數(shu)斷面(mian))、Ⅱ斷面(mian)(偶數(shu)斷面(mian))、加強斷面(mian)(偶數(shu)斷管管片）

3、波紋管(guan)拼裝：采用刻槽法(fa)施工的(de)地基(ji)，安裝吊(diao)車(che)依據(ju)刻槽深度，依次安裝底(di)部(bu)管(guan)片(pian)。底(di)部(bu)管(guan)片(pian)安裝完成后對(dui)剩(sheng)余管(guan)片(pian)進行安裝。管(guan)片(pian)安裝同平(ping)基(ji)上的(de)鋼波紋管(guan)施工。

4、加強斷面拼裝

當波紋管(guan)涵直徑(jing)較大(da)、填土(tu)高度較高時(shi)，必須設置(zhi)加(jia)(jia)強(qiang)管(guan)片，稱為(wei)加(jia)(jia)強(qiang)圈(quan)”，加(jia)(jia)強(qiang)斷面的管(guan)片安裝(zhuang)工序。
