大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)設(she)(she)拼裝支(zhi)架(jia):搭(da)設(she)(she)腳(jiao)(jiao)手(shou)架(jia)根據波紋管(guan)(guan)的直徑(jing)提前確定，采用管(guan)(guan)扣(kou)連接(jie)鋼管(guan)(guan)的方(fang)式(shi)搭(da)設(she)(she)腳(jiao)(jiao)手(shou)架(jia)，形式(shi)分A型(xing)和B型(xing)腳(jiao)(jiao)手(shou)架(jia)長(chang)度一(yi)般長(chang)25m、克(ke)0、6m、高為2d3(d為波紋管(guan)(guan)直徑(jing))，B型(xing)腳(jiao)(jiao)手(shou)架(jia)一(yi)般克(ke)為25m高依據波紋管(guan)(guan)直徑(jing)大小拼裝接(jie)縫位置(zhi)確定尺寸。腳(jiao)(jiao)手(shou)架(jia)按上(shang)述(shu)尺寸搭(da)設(she)(she)便于施工、

2、拼裝類型與(yu)搭接方式(shi)：拼裝以中心軸線為基(ji)準，由中心向兩端(duan)(duan)對稱進行(xing)安裝，直至兩端(duan)(duan)。1斷(duan)(duan)面(mian)(奇數斷(duan)(duan)面(mian))、Ⅱ斷(duan)(duan)面(mian)(偶(ou)數斷(duan)(duan)面(mian))、加強斷(duan)(duan)面(mian)(偶(ou)數斷(duan)(duan)管管片）

3、波紋(wen)管(guan)(guan)拼裝(zhuang)(zhuang)(zhuang)：采(cai)用刻(ke)槽法施工的地基(ji)(ji)，安裝(zhuang)(zhuang)(zhuang)吊車依據刻(ke)槽深度，依次(ci)安裝(zhuang)(zhuang)(zhuang)底部(bu)管(guan)(guan)片(pian)。底部(bu)管(guan)(guan)片(pian)安裝(zhuang)(zhuang)(zhuang)完成后(hou)對剩(sheng)余管(guan)(guan)片(pian)進行安裝(zhuang)(zhuang)(zhuang)。管(guan)(guan)片(pian)安裝(zhuang)(zhuang)(zhuang)同平基(ji)(ji)上的鋼波紋(wen)管(guan)(guan)施工。

4、加強斷面拼裝

當波紋管涵直徑較大、填土(tu)高度較高時，必(bi)須(xu)設置加(jia)強(qiang)(qiang)管片，稱(cheng)為加(jia)強(qiang)(qiang)圈(quan)”，加(jia)強(qiang)(qiang)斷面的管片安裝工(gong)序。
