大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼裝支架(jia)(jia):搭(da)設腳手架(jia)(jia)根據波紋(wen)管的直(zhi)徑(jing)提前確(que)定，采(cai)用管扣連接鋼(gang)管的方式(shi)搭(da)設腳手架(jia)(jia)，形式(shi)分(fen)A型和B型腳手架(jia)(jia)長度一般長25m、克(ke)0、6m、高(gao)為2d3(d為波紋(wen)管直(zhi)徑(jing))，B型腳手架(jia)(jia)一般克(ke)為25m高(gao)依(yi)據波紋(wen)管直(zhi)徑(jing)大(da)小拼裝接縫(feng)位(wei)置確(que)定尺寸。腳手架(jia)(jia)按上述尺寸搭(da)設便于(yu)施工、

2、拼裝類(lei)型與(yu)搭接方(fang)式：拼裝以中心(xin)軸線(xian)為基準，由中心(xin)向兩端對(dui)稱(cheng)進行安(an)裝，直(zhi)至(zhi)兩端。1斷(duan)(duan)面(奇數(shu)(shu)斷(duan)(duan)面)、Ⅱ斷(duan)(duan)面(偶數(shu)(shu)斷(duan)(duan)面)、加(jia)強(qiang)斷(duan)(duan)面(偶數(shu)(shu)斷(duan)(duan)管管片）

3、波(bo)紋管拼裝(zhuang)：采(cai)用刻(ke)槽法(fa)施工的地基，安裝(zhuang)吊車依(yi)據(ju)刻(ke)槽深度，依(yi)次安裝(zhuang)底部管片(pian)(pian)(pian)。底部管片(pian)(pian)(pian)安裝(zhuang)完成(cheng)后對剩余管片(pian)(pian)(pian)進(jin)行安裝(zhuang)。管片(pian)(pian)(pian)安裝(zhuang)同平(ping)基上的鋼波(bo)紋管施工。

4、加強斷面拼裝

當(dang)波紋管涵直(zhi)徑(jing)較(jiao)大、填土高度較(jiao)高時，必須設置(zhi)加(jia)強(qiang)管片，稱為(wei)加(jia)強(qiang)圈”，加(jia)強(qiang)斷面(mian)的管片安(an)裝工序。
