鋼波紋涵管混凝(ning)土配重層的(de)厚度(du)(du)與上料皮(pi)帶送料的(de)速度(du)(du)有關,速度(du)(du)增大,送入到(dao)鼓(gu)輪(lun)中的(de)混凝(ning)土量(liang)增多,噴涂到(dao)管體上的(de)厚度(du)(du)也就增加。鼓(gu)輪(lun)的(de)轉速直接(jie)影響管道表面混凝(ning)士的(de)致密(mi)性(xing)和附著(zhu)力。纏(chan)繞擠壓式(shi)。主要由上料斗、送料皮(pi)帶、纏(chan)繞皮(pi)帶、步進電機、加固網支架構成。

鋼波紋涵管施工(gong)時為啥要選擇分段施工(gong)的方法？

纏繞(rao)皮帶的松(song)緊程度影響鋼管(guan)(guan)表面混(hun)凝(ning)士的致密(mi)性。鋼制波(bo)紋(wen)管(guan)(guan)涵(han)(han)施工(gong)時,采(cai)用(yong)分段(duan)施工(gong)的辦法,預先在原拱(gong)涵(han)(han)基底用(yong)角鋼并排兩(liang)根(gen),長(chang)度依據(ju)涵(han)(han)長(chang)確定。作鋼質(zhi)涵(han)(han)管(guan)(guan)推進時的滑軌,波(bo)紋(wen)涵(han)(han)管(guan)(guan)管(guan)(guan)徑依據(ju)工(gong)程需求(qiu)可(ke)有分歧(qi)的規格,束(shu)裝管(guan)(guan)管(guan)(guan)徑為0.5m--2.5m;每節管(guan)(guan)長(chang)度3米(mi)左右。

采用內(外)法蘭螺(luo)栓(shuan)銜接。拼裝(zhuang)涵管(guan)管(guan)管(guan)徑為3m--8m。每個圓(yuan)周偏向有(you)4---15塊板(ban)構成,板(ban)與(yu)(yu)板(ban)搭接高(gao)強螺(luo)栓(shuan)緊(jin)固。假如涵長小于(yu)(yu)30米,金屬波(bo)紋管(guan)涵兩側與(yu)(yu)原涵寬度大于(yu)(yu)80cm,可將整(zheng)道金屬波(bo)紋管(guan)涵鄙人游(you)(you)或上游(you)(you)向一端推進,就位今(jin)后,再進行一端擋墻(qiang)的砌(qi)筑,周圍的回填(tian)(tian)任務，可回填(tian)(tian)沙礫碎石(shi)土。

砌(qi)(qi)筑片(pian)石(shi)(shi)等。頂部(bu)采用漿砌(qi)(qi)片(pian)石(shi)(shi)或(huo)高壓泵(beng)送膨(peng)脹(zhang)水泥沙(sha)漿。假如涵(han)洞(dong)長大于(yu)30米,鋼(gang)制波(bo)紋管涵(han)兩側與原涵(han)洞(dong)寬度(du)(du)小于(yu)80cm,可(ke)將(jiang)3m-6m長涵(han)管鄙人(ren)游或(huo)上(shang)游向-端(duan)推進,就位今后(hou),可(ke)以將(jiang)其固定,砌(qi)(qi)筑頂端(duan)的(de)片(pian)石(shi)(shi)端(duan)墻,鋼(gang)制波(bo)紋管涵(han)的(de)另-端(duan)與涵(han)洞(dong)間的(de)間距用沙(sha)袋或(huo)漿砌(qi)(qi)片(pian)石(shi)(shi)蓋住,寬度(du)(du)50cm,然后(hou)開端(duan)回埴。

兩側可(ke)用(yong)粗沙水密(mi)(mi)法密(mi)(mi)實(shi)或(huo)澆注混凝土(tu)震動棒搗實(shi);頂部(bu)采用(yong)高壓泵(beng)送膨脹水泥沙漿(jiang)。該(gai)節(jie)管(guan)(guan)周圍填(tian)筑終(zhong)了今后。將第二節(jie)管(guan)(guan)運至,進(jin)行兩管(guan)(guan)的銜(xian)(xian)接(jie)，鋼(gang)制波(bo)紋管(guan)(guan)涵的銜(xian)(xian)接(jie)方法為(wei)內法蘭螺栓銜(xian)(xian)接(jie),工人可(ke)在管(guan)(guan)內銜(xian)(xian)接(jie)。銜(xian)(xian)接(jie)終(zhong)了后,以上述一(yi)樣(yang)的辦法進(jin)行回埴。依次進(jin)行,完成整(zheng)道鐵路(lu)鋼(gang)波紋管涵的建(jian)筑任(ren)務。

工作原理:由上(shang)料(liao)斗將(jiang)混(hun)凝士送(song)到送(song)料(liao)皮帶上(shang),經送(song)料(liao)皮帶將(jiang)混(hun)凝士堆(dui)積到鋼管(guan)(guan)(guan)表(biao)面(mian)，再被纏繞皮帶施(shi)加壓(ya)(ya)力，波紋(wen)涵管(guan)(guan)(guan)混(hun)凝土(tu)被擠(ji)壓(ya)(ya)到已防(fang)腐鋼管(guan)(guan)(guan)的(de)(de)表(biao)面(mian),同時放置在混(hun)凝士被擠(ji)壓(ya)(ya)層適當位置的(de)(de)加固網也(ye)和混(hun)凝士一(yi)起被纏繞擠(ji)壓(ya)(ya)到鋼管(guan)(guan)(guan)表(biao)面(mian)。通(tong)過調節送(song)料(liao)皮帶上(shang)混(hun)凝士的(de)(de)量來確(que)定涂敷混(hun)凝士的(de)(de)厚度。公路波紋(wen)涵管(guan)(guan)(guan)：hanihanbj.com
