大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼(pin)(pin)裝支架:搭(da)設(she)腳手架根據波紋管(guan)的直(zhi)徑(jing)提前確定，采用管(guan)扣連接鋼管(guan)的方式搭(da)設(she)腳手架，形式分(fen)A型(xing)和B型(xing)腳手架長度一般長25m、克(ke)0、6m、高(gao)為(wei)(wei)2d3(d為(wei)(wei)波紋管(guan)直(zhi)徑(jing))，B型(xing)腳手架一般克(ke)為(wei)(wei)25m高(gao)依據波紋管(guan)直(zhi)徑(jing)大小拼(pin)(pin)裝接縫位置確定尺(chi)寸(cun)。腳手架按上述尺(chi)寸(cun)搭(da)設(she)便于施(shi)工、

2、拼裝類型與搭接方(fang)式：拼裝以中(zhong)心軸線為基(ji)準，由中(zhong)心向兩(liang)端(duan)對稱進行安裝，直(zhi)至兩(liang)端(duan)。1斷面(mian)(奇(qi)數(shu)斷面(mian))、Ⅱ斷面(mian)(偶數(shu)斷面(mian))、加(jia)強(qiang)斷面(mian)(偶數(shu)斷管管片）

3、波紋管(guan)拼裝(zhuang)(zhuang)：采用刻槽(cao)法施工的(de)地(di)基，安裝(zhuang)(zhuang)吊車依據刻槽(cao)深度(du)，依次安裝(zhuang)(zhuang)底部(bu)管(guan)片。底部(bu)管(guan)片安裝(zhuang)(zhuang)完成后對剩余管(guan)片進行(xing)安裝(zhuang)(zhuang)。管(guan)片安裝(zhuang)(zhuang)同平基上的(de)鋼波紋管(guan)施工。

4、加強斷面拼裝

當(dang)波紋管涵直徑較(jiao)大、填(tian)土高(gao)度(du)較(jiao)高(gao)時，必須設置(zhi)加強管片，稱為加強圈(quan)”，加強斷面的(de)管片安裝(zhuang)工(gong)序。
