大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設拼裝支架:搭(da)設腳(jiao)(jiao)手架根據波紋(wen)管(guan)的直徑(jing)(jing)提前確(que)定，采用管(guan)扣連接鋼管(guan)的方式搭(da)設腳(jiao)(jiao)手架，形式分(fen)A型(xing)和B型(xing)腳(jiao)(jiao)手架長度一般長25m、克0、6m、高為2d3(d為波紋(wen)管(guan)直徑(jing)(jing))，B型(xing)腳(jiao)(jiao)手架一般克為25m高依據波紋(wen)管(guan)直徑(jing)(jing)大小拼裝接縫(feng)位置確(que)定尺寸(cun)。腳(jiao)(jiao)手架按上(shang)述尺寸(cun)搭(da)設便于施工、

2、拼(pin)裝類型與搭(da)接方式(shi)：拼(pin)裝以中心軸線為基準，由中心向兩(liang)(liang)端(duan)(duan)對稱(cheng)進行安裝，直至兩(liang)(liang)端(duan)(duan)。1斷(duan)(duan)面(奇數(shu)斷(duan)(duan)面)、Ⅱ斷(duan)(duan)面(偶數(shu)斷(duan)(duan)面)、加強斷(duan)(duan)面(偶數(shu)斷(duan)(duan)管(guan)管(guan)片）

3、波(bo)紋管(guan)拼(pin)裝：采用刻槽(cao)(cao)法施工(gong)的(de)地(di)基(ji)，安(an)裝吊車依據刻槽(cao)(cao)深度，依次安(an)裝底部(bu)(bu)管(guan)片(pian)。底部(bu)(bu)管(guan)片(pian)安(an)裝完成后對剩余管(guan)片(pian)進(jin)行安(an)裝。管(guan)片(pian)安(an)裝同平基(ji)上的(de)鋼(gang)波(bo)紋管(guan)施工(gong)。

4、加強斷面拼裝

當波(bo)紋管(guan)(guan)涵(han)直徑較大、填土高度(du)較高時，必須設置加強(qiang)管(guan)(guan)片，稱為加強(qiang)圈”，加強(qiang)斷面的管(guan)(guan)片安裝(zhuang)工序。
