大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)拼裝支架:搭(da)設(she)腳(jiao)(jiao)手(shou)(shou)架根(gen)據波(bo)紋(wen)管的直(zhi)徑提前確定(ding)，采用管扣連接鋼管的方式(shi)搭(da)設(she)腳(jiao)(jiao)手(shou)(shou)架，形(xing)式(shi)分A型和B型腳(jiao)(jiao)手(shou)(shou)架長度一(yi)般(ban)長25m、克0、6m、高為2d3(d為波(bo)紋(wen)管直(zhi)徑)，B型腳(jiao)(jiao)手(shou)(shou)架一(yi)般(ban)克為25m高依據波(bo)紋(wen)管直(zhi)徑大小拼裝接縫(feng)位置確定(ding)尺寸。腳(jiao)(jiao)手(shou)(shou)架按(an)上述尺寸搭(da)設(she)便(bian)于(yu)施工、

2、拼裝類型與搭接方式：拼裝以(yi)中心軸線為基(ji)準，由中心向兩(liang)端(duan)對(dui)稱進(jin)行安裝，直至(zhi)兩(liang)端(duan)。1斷(duan)(duan)面(奇數(shu)斷(duan)(duan)面)、Ⅱ斷(duan)(duan)面(偶(ou)(ou)數(shu)斷(duan)(duan)面)、加(jia)強斷(duan)(duan)面(偶(ou)(ou)數(shu)斷(duan)(duan)管(guan)管(guan)片）

3、波(bo)紋管(guan)(guan)拼(pin)裝(zhuang)(zhuang)(zhuang)：采用刻槽(cao)(cao)法(fa)施(shi)工(gong)的地基(ji)，安(an)裝(zhuang)(zhuang)(zhuang)吊車依(yi)據刻槽(cao)(cao)深度，依(yi)次(ci)安(an)裝(zhuang)(zhuang)(zhuang)底(di)部(bu)管(guan)(guan)片(pian)。底(di)部(bu)管(guan)(guan)片(pian)安(an)裝(zhuang)(zhuang)(zhuang)完(wan)成(cheng)后對剩余管(guan)(guan)片(pian)進行安(an)裝(zhuang)(zhuang)(zhuang)。管(guan)(guan)片(pian)安(an)裝(zhuang)(zhuang)(zhuang)同平基(ji)上的鋼波(bo)紋管(guan)(guan)施(shi)工(gong)。

4、加強斷面拼裝

當波紋(wen)管(guan)(guan)涵直徑較(jiao)大、填土高度(du)較(jiao)高時，必須設置加(jia)強(qiang)管(guan)(guan)片，稱為(wei)加(jia)強(qiang)圈”，加(jia)強(qiang)斷面的管(guan)(guan)片安裝工序(xu)。
