大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼裝支架:搭設腳手架根據波紋(wen)管的(de)直徑提(ti)前確定(ding)，采用(yong)管扣連接(jie)鋼(gang)管的(de)方式搭設腳手架，形(xing)式分A型(xing)和B型(xing)腳手架長(chang)度(du)一般長(chang)25m、克0、6m、高(gao)為(wei)(wei)2d3(d為(wei)(wei)波紋(wen)管直徑)，B型(xing)腳手架一般克為(wei)(wei)25m高(gao)依據波紋(wen)管直徑大小(xiao)拼裝接(jie)縫位(wei)置(zhi)確定(ding)尺寸(cun)。腳手架按上述尺寸(cun)搭設便于施工(gong)、

2、拼(pin)裝類型(xing)與搭接方(fang)式：拼(pin)裝以中心軸(zhou)線(xian)為基準，由中心向(xiang)兩端(duan)對稱進行安裝，直至兩端(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)管管片）

3、波紋管拼(pin)裝(zhuang)：采用刻槽法施(shi)工的(de)地基，安(an)(an)裝(zhuang)吊車依據刻槽深度，依次(ci)安(an)(an)裝(zhuang)底部管片(pian)(pian)。底部管片(pian)(pian)安(an)(an)裝(zhuang)完成后對剩(sheng)余管片(pian)(pian)進(jin)行安(an)(an)裝(zhuang)。管片(pian)(pian)安(an)(an)裝(zhuang)同(tong)平(ping)基上的(de)鋼波紋管施(shi)工。

4、加強斷面拼裝

當波紋(wen)管(guan)涵直徑較大、填土高度較高時，必須設置加(jia)強(qiang)(qiang)管(guan)片，稱為加(jia)強(qiang)(qiang)圈”，加(jia)強(qiang)(qiang)斷面(mian)的管(guan)片安裝工序。
