大直徑鋼波紋管拼裝方法你知道嗎？

1、搭設(she)(she)(she)拼裝支架(jia):搭設(she)(she)(she)腳(jiao)手架(jia)根據(ju)(ju)波紋管(guan)的(de)直(zhi)(zhi)徑提前確定(ding)，采用管(guan)扣連(lian)接(jie)鋼管(guan)的(de)方式(shi)搭設(she)(she)(she)腳(jiao)手架(jia)，形(xing)式(shi)分A型和B型腳(jiao)手架(jia)長度(du)一(yi)般(ban)(ban)長25m、克(ke)0、6m、高為2d3(d為波紋管(guan)直(zhi)(zhi)徑)，B型腳(jiao)手架(jia)一(yi)般(ban)(ban)克(ke)為25m高依據(ju)(ju)波紋管(guan)直(zhi)(zhi)徑大小拼裝接(jie)縫(feng)位(wei)置(zhi)確定(ding)尺寸。腳(jiao)手架(jia)按上(shang)述尺寸搭設(she)(she)(she)便于施工、

2、拼(pin)裝類型與搭接(jie)方(fang)式：拼(pin)裝以(yi)中(zhong)心軸線為基準，由中(zhong)心向兩端對稱進行(xing)安裝，直(zhi)至兩端。1斷(duan)面(奇(qi)數斷(duan)面)、Ⅱ斷(duan)面(偶數斷(duan)面)、加強斷(duan)面(偶數斷(duan)管(guan)管(guan)片(pian)）

3、波紋(wen)管拼裝：采(cai)用刻(ke)槽法施工(gong)的地(di)基，安(an)(an)裝吊車依據刻(ke)槽深度，依次安(an)(an)裝底部(bu)管片(pian)。底部(bu)管片(pian)安(an)(an)裝完成后對(dui)剩余(yu)管片(pian)進行安(an)(an)裝。管片(pian)安(an)(an)裝同平基上的鋼(gang)波紋(wen)管施工(gong)。

鋼波紋管

首圈(quan)波(bo)紋(wen)(wen)管圈(quan)為奇(qi)數(shu)斷(duan)面，拼裝(zhuang)(zhuang)時應將(jiang)(jiang)管片立于地(di)上(shang)安裝(zhuang)(zhuang)，使(shi)用(yong)(yong)(yong)鐵(tie)(tie)鉤的(de)(de)一端(duan)(duan)勾住(zhu)I斷(duan)面片(1#管片)波(bo)紋(wen)(wen)管管片螺(luo)(luo)絲囗(wei)，用(yong)(yong)(yong)12噸的(de)(de)吊(diao)車勾住(zhu)鐵(tie)(tie)鉤的(de)(de)另一端(duan)(duan)，將(jiang)(jiang)波(bo)紋(wen)(wen)管片立于墊層上(shang)，然后(hou)使(shi)用(yong)(yong)(yong)同樣的(de)(de)辦法將(jiang)(jiang)第(di)二(er)片(6#管片)波(bo)紋(wen)(wen)管管片按圖(tu)(tu)3、21斷(duan)面所(suo)示(shi)的(de)(de)搭(da)接(jie)(jie)方式放置，使(shi)用(yong)(yong)(yong)撬棍將(jiang)(jiang)管片的(de)(de)螺(luo)(luo)栓口(kou)對齊，將(jiang)(jiang)提前準備好(hao)(hao)的(de)(de)螺(luo)(luo)栓螺(luo)(luo)紋(wen)(wen)部(bu)涂上(shang)渢滑劑，由內冋外(wai)插入孔(kong)位；波(bo)紋(wen)(wen)管外(wai)側套上(shang)凹(ao)墊圈(quan)或凸墊圈(quan)，遇波(bo)使(shi)用(yong)(yong)(yong)凸墊圈(quan)，遇波(bo)峰使(shi)用(yong)(yong)(yong)凹(ao)墊圈(quan)墊圈(quan)外(wai)側旋上(shang)螺(luo)(luo)母，在用(yong)(yong)(yong)套筒扳手(shou)預緊(jin)(jin)螺(luo)(luo)母，然后(hou)使(shi)用(yong)(yong)(yong)電動扳手(shou)緊(jin)(jin)固(gu)螺(luo)(luo)母兩塊板片洤全部(bu)安裝(zhuang)(zhuang)完畢(bi);波(bo)紋(wen)(wen)管的(de)(de)螺(luo)(luo)栓安裝(zhuang)(zhuang)完畢(bi)后(hou)，需采用(yong)(yong)(yong)專用(yong)(yong)(yong)注膠(jiao)槍于端(duan)(duan)部(bu)接(jie)(jie)合處、緊(jin)(jin)回件連接(jie)(jie)的(de)(de)螺(luo)(luo)栓孔(kong)空隙處涂抹中性(xing)硅(gui)酮(tong)耐候膠(jiao)。緊(jin)(jin)接(jie)(jie)著按2#管片、5#管片、3#管片、4#管片的(de)(de)施工拼裝(zhuang)(zhuang)順序，拼裝(zhuang)(zhuang)好(hao)(hao)首圈(quan)波(bo)紋(wen)(wen)管圖(tu)(tu)36偶(ou)數(shu)、奇(qi)數(shu)斷(duan)面交(jiao)替拼裝(zhuang)(zhuang)順序

4、加強斷面拼裝

當波紋管(guan)涵直徑較(jiao)大、填土高度(du)較(jiao)高時，必須設置加強(qiang)管(guan)片(pian)，稱為加強(qiang)圈”，加強(qiang)斷面(mian)的管(guan)片(pian)安裝工序。
