大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設拼(pin)裝(zhuang)支架(jia):搭設腳手(shou)架(jia)根據(ju)波(bo)紋(wen)管(guan)的直徑(jing)(jing)提(ti)前確(que)定(ding)，采用管(guan)扣連接(jie)鋼管(guan)的方式搭設腳手(shou)架(jia)，形式分(fen)A型(xing)和B型(xing)腳手(shou)架(jia)長度一(yi)般(ban)長25m、克0、6m、高為2d3(d為波(bo)紋(wen)管(guan)直徑(jing)(jing))，B型(xing)腳手(shou)架(jia)一(yi)般(ban)克為25m高依(yi)據(ju)波(bo)紋(wen)管(guan)直徑(jing)(jing)大小拼(pin)裝(zhuang)接(jie)縫位置確(que)定(ding)尺寸。腳手(shou)架(jia)按上述尺寸搭設便于(yu)施工、

2、拼裝類型與搭接方(fang)式：拼裝以中(zhong)心軸(zhou)線為基準，由中(zhong)心向(xiang)兩(liang)端對(dui)稱(cheng)進(jin)行安(an)裝，直至兩(liang)端。1斷面(奇數(shu)(shu)斷面)、Ⅱ斷面(偶數(shu)(shu)斷面)、加強斷面(偶數(shu)(shu)斷管管片）

3、波(bo)紋管(guan)拼(pin)裝(zhuang)(zhuang)(zhuang)：采(cai)用刻槽法施工(gong)的地基，安裝(zhuang)(zhuang)(zhuang)吊車依據刻槽深度，依次安裝(zhuang)(zhuang)(zhuang)底部管(guan)片(pian)。底部管(guan)片(pian)安裝(zhuang)(zhuang)(zhuang)完成后對剩(sheng)余管(guan)片(pian)進行安裝(zhuang)(zhuang)(zhuang)。管(guan)片(pian)安裝(zhuang)(zhuang)(zhuang)同平(ping)基上的鋼波(bo)紋管(guan)施工(gong)。

4、加強斷面拼裝

當(dang)波紋管涵直徑(jing)較(jiao)大(da)、填(tian)土高度較(jiao)高時，必須設(she)置加強(qiang)管片，稱為加強(qiang)圈”，加強(qiang)斷面的管片安(an)裝(zhuang)工序(xu)。
