大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)(she)拼裝支(zhi)架(jia):搭設(she)(she)腳(jiao)手(shou)架(jia)根據(ju)(ju)波(bo)紋管(guan)(guan)的(de)(de)直(zhi)(zhi)徑提前確(que)定，采用管(guan)(guan)扣連接(jie)鋼管(guan)(guan)的(de)(de)方式搭設(she)(she)腳(jiao)手(shou)架(jia)，形式分A型和B型腳(jiao)手(shou)架(jia)長(chang)度一(yi)般(ban)長(chang)25m、克(ke)0、6m、高(gao)為2d3(d為波(bo)紋管(guan)(guan)直(zhi)(zhi)徑)，B型腳(jiao)手(shou)架(jia)一(yi)般(ban)克(ke)為25m高(gao)依據(ju)(ju)波(bo)紋管(guan)(guan)直(zhi)(zhi)徑大小拼裝接(jie)縫位置確(que)定尺寸。腳(jiao)手(shou)架(jia)按上(shang)述尺寸搭設(she)(she)便(bian)于施工、

2、拼裝類型與搭(da)接方式：拼裝以中(zhong)心軸線為基準，由(you)中(zhong)心向兩端對稱進行安裝，直至兩端。1斷(duan)(duan)面(奇數斷(duan)(duan)面)、Ⅱ斷(duan)(duan)面(偶數斷(duan)(duan)面)、加(jia)強斷(duan)(duan)面(偶數斷(duan)(duan)管管片）

3、波紋管拼裝：采用刻槽(cao)法施工的(de)地基，安裝吊車依據(ju)刻槽(cao)深度(du)，依次安裝底部管片。底部管片安裝完成后對剩余管片進行安裝。管片安裝同平基上(shang)的(de)鋼波紋管施工。

4、加強斷面拼裝

當波紋管(guan)涵直徑較(jiao)大(da)、填土(tu)高(gao)度(du)較(jiao)高(gao)時，必須(xu)設(she)置加(jia)(jia)強(qiang)管(guan)片(pian)，稱(cheng)為加(jia)(jia)強(qiang)圈”，加(jia)(jia)強(qiang)斷(duan)面的管(guan)片(pian)安裝工序。
