鋼波紋管涵(han)擴口(kou)外層不(bu)(bu)(bu)成型(xing)，可能(neng)是由(you)于擴口(kou)形式不(bu)(bu)(bu)正確，應調為自動，擴口(kou)，擴口(kou)閥隨動。還有是外層真空腔(qiang)的2、3區未(wei)打開，或(huo)外層真空不(bu)(bu)(bu)穩定，進行查看處理(li)(li)。正常充氣(qi)氣(qi)路(lu)不(bu)(bu)(bu)通，做(zuo)擴口(kou)時(shi)與外界大氣(qi)不(bu)(bu)(bu)相(xiang)通，查看管路(lu)銜接及正常充氣(qi)氣(qi)孔是否堵塞，進行處理(li)(li)。

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.

鋼波紋管

快充氣壓(ya)力(li)大(da)，吹破(po)管(guan)坯，恰(qia)當(dang)調(diao)整(zheng)(zheng)快充氣壓(ya)力(li)。正常(chang)充氣壓(ya)力(li)小，恰(qia)當(dang)調(diao)整(zheng)(zheng)正常(chang)充氣。擴口(kou)間隔限位(wei)開關(guan)未起作(zuo)用(yong)(yong)，調(diao)整(zheng)(zheng)到恰(qia)當(dang)位(wei)置(zhi)。成型機反(fan)面擴口(kou)閥隨動(dong)設備未起作(zuo)用(yong)(yong)，相(xiang)對調(diao)整(zheng)(zheng)。鋼波(bo)紋(wen)管(guan)涵的外(wai)壁呈環形(xing)波(bo)紋(wen)狀結構。

大(da)大(da)增強了管(guan)材的環剛度，從(cong)而增強了管(guan)道對土壤負荷的抵抗力。與同質料規格的實壁(bi)相管(guan)比，鋼波(bo)紋管(guan)涵(han)(han)能(neng)節約一半左右(you)的原材料，鋼波(bo)紋管(guan)涵(han)(han)工程造價(jia)低。鋼波(bo)紋管(guan)涵(han)(han)的化(hua)學穩定性好，不(bu)受地面必定程度的不(bu)均勻沉降的影響，能(neng)夠不(bu)必管(guan)件(jian)直(zhi)接鋪在(zai)略為不(bu)直(zhi)的溝槽內等等。

鋼波紋管

鋼(gang)波(bo)(bo)紋(wen)管(guan)涵以高密(mi)度(du)聚乙烯(xi)為質料的(de)一種新型輕(qing)質管(guan)材(cai)，具有重量輕(qing)、耐高壓、韌性好、施工快壽命(ming)長等特色，其優異(yi)的(de)管(guan)壁(bi)結構(gou)設計，銜接(jie)便利、牢靠。當鋼(gang)波(bo)(bo)紋(wen)管(guan)涵兩端對接(jie)部(bu)分的(de)對接(jie)強度(du)不高時，主張采納粘接(jie)辦法(fa)和(he)錫焊辦法(fa)來進行對鋼(gang)波(bo)(bo)紋(wen)管(guan)涵的(de)對接(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/
