大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝(zhuang)支架(jia):搭設腳(jiao)手架(jia)根(gen)據波紋管(guan)的(de)(de)直(zhi)(zhi)徑(jing)提前(qian)確定(ding)，采用管(guan)扣連接鋼管(guan)的(de)(de)方(fang)式搭設腳(jiao)手架(jia)，形式分A型(xing)(xing)和B型(xing)(xing)腳(jiao)手架(jia)長(chang)度一般(ban)長(chang)25m、克(ke)0、6m、高(gao)為2d3(d為波紋管(guan)直(zhi)(zhi)徑(jing))，B型(xing)(xing)腳(jiao)手架(jia)一般(ban)克(ke)為25m高(gao)依據波紋管(guan)直(zhi)(zhi)徑(jing)大小拼裝(zhuang)接縫位置確定(ding)尺(chi)寸。腳(jiao)手架(jia)按上述尺(chi)寸搭設便于施工、

2、拼裝類(lei)型與搭(da)接方式：拼裝以中心(xin)軸(zhou)線(xian)為(wei)基準，由中心(xin)向兩端(duan)對稱進(jin)行安裝，直至兩端(duan)。1斷(duan)面(mian)(奇數斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶(ou)數斷(duan)面(mian))、加強(qiang)斷(duan)面(mian)(偶(ou)數斷(duan)管管片）

3、波紋(wen)(wen)管(guan)拼裝：采用刻(ke)槽(cao)法施工(gong)的地基(ji)，安(an)(an)裝吊車(che)依(yi)據刻(ke)槽(cao)深(shen)度，依(yi)次安(an)(an)裝底(di)部管(guan)片(pian)。底(di)部管(guan)片(pian)安(an)(an)裝完成后對剩余管(guan)片(pian)進行安(an)(an)裝。管(guan)片(pian)安(an)(an)裝同(tong)平(ping)基(ji)上的鋼(gang)波紋(wen)(wen)管(guan)施工(gong)。

4、加強斷面拼裝

當波紋管(guan)涵(han)直徑較大、填土高(gao)度較高(gao)時，必須設置加(jia)強(qiang)管(guan)片(pian)，稱為加(jia)強(qiang)圈”，加(jia)強(qiang)斷(duan)面的管(guan)片(pian)安裝(zhuang)工序。
