鋼波紋管涵擴口(kou)(kou)(kou)外(wai)層(ceng)不(bu)成型,可能(neng)是(shi)(shi)由于擴口(kou)(kou)(kou)形式不(bu)正確,應調為自動,擴口(kou)(kou)(kou),擴口(kou)(kou)(kou)閥(fa)隨動。還有是(shi)(shi)外(wai)層(ceng)真空腔的2、3區未(wei)打開,或(huo)外(wai)層(ceng)真空不(bu)穩定(ding),進(jin)行查看處理。正常(chang)充氣(qi)氣(qi)路不(bu)通,做擴口(kou)(kou)(kou)時與外(wai)界(jie)大(da)氣(qi)不(bu)相(xiang)通,查看管路銜接(jie)及正常(chang)充氣(qi)氣(qi)孔是(shi)(shi)否堵(du)塞,進(jin)行處理。
The outer layer of the expansion of steel corrugated pipe culvert is not formed, which may be due to the incorrect form of expansion, and it should be adjusted to automatic, flared and the expansion valve shall follow. There are also zones 2 and 3 of outer vacuum cavity not open or outer vacuum is unstable, and the inspection and treatment is conducted. The normal air filling circuit is not connected with the external atmosphere when expanding. Check whether the pipeline connection and normal air filling hole are blocked, and handle.
快充(chong)氣壓(ya)力(li)(li)(li)大,吹破管坯(pi),恰(qia)當調整(zheng)快充(chong)氣壓(ya)力(li)(li)(li)。正(zheng)常(chang)充(chong)氣壓(ya)力(li)(li)(li)小,恰(qia)當調整(zheng)正(zheng)常(chang)充(chong)氣。擴口間隔限(xian)位(wei)開(kai)關未起作(zuo)(zuo)用(yong)(yong),調整(zheng)到(dao)恰(qia)當位(wei)置。成(cheng)型機反面擴口閥隨動(dong)設備未起作(zuo)(zuo)用(yong)(yong),相對調整(zheng)。鋼波(bo)紋管涵的(de)外(wai)壁呈環形波(bo)紋狀結構。
大大增強了(le)管(guan)(guan)(guan)材(cai)的(de)環(huan)剛度(du),從而增強了(le)管(guan)(guan)(guan)道(dao)對土壤負荷的(de)抵抗(kang)力。與同質料規格(ge)的(de)實壁相管(guan)(guan)(guan)比,鋼(gang)波紋管(guan)(guan)(guan)涵能節約一半左右的(de)原材(cai)料,鋼(gang)波紋管(guan)(guan)(guan)涵工程(cheng)造價低。鋼(gang)波紋管(guan)(guan)(guan)涵的(de)化學穩定性好,不受(shou)地面(mian)必定程(cheng)度(du)的(de)不均勻沉降的(de)影響,能夠(gou)不必管(guan)(guan)(guan)件直接鋪在(zai)略為(wei)不直的(de)溝槽(cao)內等等。
鋼(gang)波紋管(guan)涵(han)(han)以(yi)高(gao)(gao)密度聚乙烯(xi)為質料的(de)一種新型輕質管(guan)材,具(ju)有重量輕、耐高(gao)(gao)壓、韌性(xing)好(hao)、施工快(kuai)壽命長等特色(se),其(qi)優異的(de)管(guan)壁(bi)結構設(she)計,銜接(jie)(jie)(jie)(jie)便利、牢靠。當鋼(gang)波紋管(guan)涵(han)(han)兩端對(dui)接(jie)(jie)(jie)(jie)部分的(de)對(dui)接(jie)(jie)(jie)(jie)強度不高(gao)(gao)時,主張采納粘接(jie)(jie)(jie)(jie)辦法(fa)和錫焊辦法(fa)來進行對(dui)鋼(gang)波紋管(guan)涵(han)(han)的(de)對(dui)接(jie)(jie)(jie)(jie)。
由于這樣的話能夠對鋼波紋管涵對接口處不必做很大很細的加工。如果說在對接的時分對接口要求有必定的對接強度,那咱們能夠采用卷邊的辦法將鋼波紋管涵的接口處卡在事前準備好的法蘭上,在進行對鋼波紋管涵接口的焊接。//hanihanbj.com/
