鋼波紋管涵(han)擴(kuo)(kuo)(kuo)口(kou)外(wai)層不成型，可能是由于擴(kuo)(kuo)(kuo)口(kou)形式不正確，應調為自動(dong)，擴(kuo)(kuo)(kuo)口(kou)，擴(kuo)(kuo)(kuo)口(kou)閥隨動(dong)。還有是外(wai)層真(zhen)空腔的2、3區未打開，或(huo)外(wai)層真(zhen)空不穩定(ding)，進行(xing)查(cha)看(kan)(kan)處理。正常(chang)充氣(qi)氣(qi)路(lu)不通，做擴(kuo)(kuo)(kuo)口(kou)時與外(wai)界大氣(qi)不相通，查(cha)看(kan)(kan)管路(lu)銜接及(ji)正常(chang)充氣(qi)氣(qi)孔(kong)是否堵塞，進行(xing)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.

鋼波紋管

快充氣壓(ya)力(li)(li)大，吹破管坯(pi)，恰當調(diao)整(zheng)快充氣壓(ya)力(li)(li)。正常(chang)充氣壓(ya)力(li)(li)小，恰當調(diao)整(zheng)正常(chang)充氣。擴口間隔限位(wei)開關未(wei)起作用，調(diao)整(zheng)到恰當位(wei)置。成型機反面擴口閥隨動設備未(wei)起作用，相對調(diao)整(zheng)。鋼波紋(wen)管涵(han)的外壁呈(cheng)環形(xing)波紋(wen)狀結構。

大大增(zeng)強了管(guan)(guan)材的環剛度，從而增(zeng)強了管(guan)(guan)道對(dui)土壤負荷的抵抗力。與(yu)同(tong)質料規格的實壁相(xiang)管(guan)(guan)比，鋼波紋(wen)管(guan)(guan)涵能(neng)節約一半(ban)左右的原材料，鋼波紋(wen)管(guan)(guan)涵工程(cheng)造價低。鋼波紋(wen)管(guan)(guan)涵的化學(xue)穩(wen)定性好，不(bu)受地面必定程(cheng)度的不(bu)均(jun)勻沉降(jiang)的影響，能(neng)夠不(bu)必管(guan)(guan)件直接(jie)鋪在略為不(bu)直的溝槽(cao)內等等。

鋼波紋管

鋼(gang)波紋(wen)管(guan)(guan)(guan)涵以高密(mi)度(du)聚(ju)乙烯為質(zhi)料的一種新(xin)型(xing)輕質(zhi)管(guan)(guan)(guan)材(cai)，具(ju)有重量輕、耐高壓(ya)、韌性好、施工快壽(shou)命(ming)長等(deng)特色，其優(you)異(yi)的管(guan)(guan)(guan)壁結構(gou)設計，銜(xian)接(jie)便(bian)利(li)、牢靠。當(dang)鋼(gang)波紋(wen)管(guan)(guan)(guan)涵兩端對(dui)接(jie)部分的對(dui)接(jie)強度(du)不高時(shi)，主張采納粘接(jie)辦法(fa)(fa)和錫焊辦法(fa)(fa)來(lai)進行對(dui)鋼(gang)波紋(wen)管(guan)(guan)(guan)涵的對(dui)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/
