大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)裝支架:搭設腳(jiao)手架根據(ju)波紋管(guan)(guan)的直徑(jing)提(ti)前確定，采用管(guan)(guan)扣連接鋼管(guan)(guan)的方式搭設腳(jiao)手架，形式分A型(xing)和B型(xing)腳(jiao)手架長度一般長25m、克0、6m、高為2d3(d為波紋管(guan)(guan)直徑(jing))，B型(xing)腳(jiao)手架一般克為25m高依(yi)據(ju)波紋管(guan)(guan)直徑(jing)大小拼(pin)裝接縫位置確定尺(chi)(chi)寸(cun)。腳(jiao)手架按上述(shu)尺(chi)(chi)寸(cun)搭設便于施工、

2、拼裝類型與搭(da)接方式：拼裝以(yi)中心(xin)軸線為基(ji)準，由中心(xin)向兩端對稱進(jin)行安(an)裝，直至(zhi)兩端。1斷面(mian)(奇(qi)數(shu)(shu)斷面(mian))、Ⅱ斷面(mian)(偶數(shu)(shu)斷面(mian))、加(jia)強斷面(mian)(偶數(shu)(shu)斷管(guan)管(guan)片）

3、波(bo)紋管拼裝(zhuang)(zhuang)：采用刻槽法施工(gong)的地基，安(an)裝(zhuang)(zhuang)吊車(che)依據刻槽深度(du)，依次安(an)裝(zhuang)(zhuang)底部管片。底部管片安(an)裝(zhuang)(zhuang)完(wan)成后對剩(sheng)余(yu)管片進行安(an)裝(zhuang)(zhuang)。管片安(an)裝(zhuang)(zhuang)同平基上的鋼(gang)波(bo)紋管施工(gong)。

4、加強斷面拼裝

當(dang)波(bo)紋(wen)管涵直(zhi)徑較大、填土高度(du)較高時，必須設置加(jia)(jia)強管片(pian)(pian)，稱(cheng)為加(jia)(jia)強圈”，加(jia)(jia)強斷面(mian)的管片(pian)(pian)安(an)裝工序。
