鋼波紋管涵擴口(kou)外層(ceng)不(bu)(bu)(bu)成型，可(ke)能(neng)是由于(yu)擴口(kou)形式不(bu)(bu)(bu)正(zheng)確，應調為自動，擴口(kou)，擴口(kou)閥隨動。還有是外層(ceng)真空腔的2、3區未打開，或外層(ceng)真空不(bu)(bu)(bu)穩定，進行查(cha)看(kan)(kan)處理。正(zheng)常充氣(qi)(qi)氣(qi)(qi)路不(bu)(bu)(bu)通，做擴口(kou)時與(yu)外界大(da)氣(qi)(qi)不(bu)(bu)(bu)相通，查(cha)看(kan)(kan)管路銜接(jie)及(ji)正(zheng)常充氣(qi)(qi)氣(qi)(qi)孔(kong)是否堵塞，進行處理。
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(kuai)充(chong)氣(qi)壓(ya)力大，吹破管(guan)坯，恰(qia)當調(diao)整(zheng)(zheng)快(kuai)充(chong)氣(qi)壓(ya)力。正常充(chong)氣(qi)壓(ya)力小，恰(qia)當調(diao)整(zheng)(zheng)正常充(chong)氣(qi)。擴口間(jian)隔限(xian)位開關未(wei)(wei)起(qi)作用，調(diao)整(zheng)(zheng)到恰(qia)當位置。成型機(ji)反面擴口閥隨(sui)動設備未(wei)(wei)起(qi)作用，相(xiang)對調(diao)整(zheng)(zheng)。鋼波紋管(guan)涵的外壁(bi)呈環形波紋狀結構。
大(da)大(da)增強了(le)(le)管材的(de)(de)環(huan)剛度，從(cong)而(er)增強了(le)(le)管道(dao)對土(tu)壤負荷的(de)(de)抵抗力。與(yu)同(tong)質料(liao)規(gui)格(ge)的(de)(de)實壁相管比，鋼(gang)波(bo)紋(wen)管涵能(neng)節約一半(ban)左右的(de)(de)原材料(liao)，鋼(gang)波(bo)紋(wen)管涵工程造價低。鋼(gang)波(bo)紋(wen)管涵的(de)(de)化學穩定(ding)性好，不受(shou)地面(mian)必定(ding)程度的(de)(de)不均(jun)勻沉降的(de)(de)影響，能(neng)夠不必管件直接鋪在(zai)略為(wei)不直的(de)(de)溝槽內等等。
鋼(gang)波紋(wen)(wen)管(guan)涵以高密度(du)聚乙(yi)烯為質(zhi)料的一(yi)種新型(xing)輕質(zhi)管(guan)材，具有(you)重量輕、耐高壓、韌性好、施工快壽命長(chang)等特色，其(qi)優異的管(guan)壁(bi)結構設(she)計，銜接便利(li)、牢靠。當鋼(gang)波紋(wen)(wen)管(guan)涵兩端(duan)對(dui)接部分的對(dui)接強度(du)不(bu)高時，主張采(cai)納粘接辦法(fa)和錫(xi)焊辦法(fa)來(lai)進行(xing)對(dui)鋼(gang)波紋(wen)(wen)管(guan)涵的對(dui)接。
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/
