當鋼波紋管兩頭對(dui)(dui)接部分的(de)(de)對(dui)(dui)接強(qiang)(qiang)度不高(gao)時,主(zhu)張采納粘接辦法(fa)和(he)錫焊辦法(fa)來(lai)進行(xing)對(dui)(dui)鋼波(bo)紋(wen)管(guan)的(de)(de)對(dui)(dui)接,由于這(zhe)樣(yang)的(de)(de)話可以對(dui)(dui)鋼波(bo)紋(wen)管(guan)對(dui)(dui)接口(kou)處不用(yong)做很大很細的(de)(de)加工。如果說在對(dui)(dui)接的(de)(de)時候對(dui)(dui)接口(kou)要求(qiu)有必(bi)定(ding)的(de)(de)對(dui)(dui)接強(qiang)(qiang)度,那咱們可以選用(yong)卷邊的(de)(de)辦法(fa)將(jiang)鋼波(bo)紋(wen)管(guan)的(de)(de)接口(kou)處卡(ka)在事先準備好的(de)(de)法(fa)蘭(lan)上(shang),在進行(xing)對(dui)(dui)鋼波(bo)紋(wen)管(guan)接口(kou)的(de)(de)焊接。
鋼波紋管無微不至的關心讓我很感動.....
在(zai)咱們對(dui)鋼波紋管(guan)進行對(dui)接(jie)(jie)時必定要(yao)保證對(dui)接(jie)(jie)口處(chu)的氣密(mi)性,如果在(zai)對(dui)接(jie)(jie)時操作失(shi)誤對(dui)造成鋼波紋管(guan)在(zai)整個工(gong)程傍邊處(chu)在(zai)滲(shen)漏傍邊,大大縮短(duan)工(gong)程的運用壽命(ming)。咱們常說的一般波紋涵(han)管(guan)必定不能(neng)運用銅焊和(he)熔化的辦法(fa)來邊接(jie)(jie),我需要(yao)求(qiu)運用鋼焊和(he)熔化焊來處(chu)理對(dui)接(jie)(jie)問題(ti),仄運用無硫(liu)鎳波紋管(guan)。
此時需要留意的(de)(de)是要保證鋼(gang)波(bo)紋(wen)(wen)管不受(shou)很高(gao)(gao)的(de)(de)溫度(du)影(ying)響(xiang),如果一(yi)但(dan)發現(xian)鋼(gang)波(bo)紋(wen)(wen)管的(de)(de)溫度(du)過(guo)高(gao)(gao)時以采納(na)對應(ying)(ying)的(de)(de)措(cuo)施來(lai)下降鋼(gang)波(bo)紋(wen)(wen)管的(de)(de)溫度(du),這樣做(zuo)是為(wei)了防(fang)止波(bo)紋(wen)(wen)具有(you)(you)的(de)(de)彈性在過(guo)高(gao)(gao)的(de)(de)溫度(du)下失去應(ying)(ying)有(you)(you)的(de)(de)彈性功用。在公路工程施工中,鋼(gang)波(bo)紋(wen)(wen)管施工長短常(chang)紐(niu)帶的(de)(de)內(nei)容。
但(dan)一(yi)些施(shi)工(gong)(gong)(gong)單位(wei)忽視采納質量(liang)操控(kong)措施(shi),規劃(hua)不到位(wei),導(dao)致工(gong)(gong)(gong)程(cheng)建造仍舊存在缺乏,主要體(ti)現(xian)在以(yi)下方(fang)面。鋼波紋管承載力(li)過(guo)低表現(xian)為承載力(li)未(wei)能知足(zu)規劃(hua)規范(fan)要求,施(shi)工(gong)(gong)(gong)職工(gong)(gong)(gong)質量(liang)操控(kong)認識稀薄,沒有遵從技(ji)術規范(fan)尺度開展鋼波紋管施(shi)工(gong)(gong)(gong)。
現以1-5m鋼波紋管(guan)工(gong)(gong)(gong)(gong)程(cheng)實例鋼波紋管(guan)工(gong)(gong)(gong)(gong)程(cheng)施(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝操控簡(jian)述(shu)如下。某(mou)高速公路由于(yu)(yu)工(gong)(gong)(gong)(gong)期(qi)較緊,考慮到原規(gui)劃為1-2m石(shi)拱(gong)涵(han)(han),而且其上有高達20m左右的涵(han)(han)頂(ding)填(tian)土,由于(yu)(yu)石(shi)拱(gong)涵(han)(han)施(shi)工(gong)(gong)(gong)(gong)進度(du)較慢,為加速施(shi)工(gong)(gong)(gong)(gong)進度(du),業(ye)主部分要(yao)求(qiu)將原規(gui)劃石(shi)拱(gong)涵(han)(han)變更規(gui)劃為1-5m鋼波紋管(guan)工(gong)(gong)(gong)(gong)程(cheng)涵(han)(han)。
以保證施工質量,加速工程建造進度。波紋管涵為直徑5m的拼裝波紋管,全長110m,填方高度達20余米。管涵管節選用Q235-A熱軋鋼板,每圈由8塊鋼板銜接組成全體,再進行縱向銜接成型。銜接螺栓選用M208.8級高強度螺栓及HRC35級弧形墊圈,鋼板外表經由熱鍍鋅處理。管涵根底厚度為120cm。洞口鋪砌及護坡選用M7.5漿砌片石鋪砌或選用鋼筋混凝土澆筑洞口。管涵流水面坡度為1%~3%。//hanihanbj.com/
