鋼波紋管和高強(qiang)度螺栓、螺母，出廠前有必要進(jin)行熱(re)鍍鋅防腐處(chu)理。每走一批貨都查驗并附(fu)產品合格證。施工(gong)準備施工(gong)所需(xu)鋼波紋管由工(gong)廠規范化(hua)消費后運(yun)送施工(gong)現場(chang)(chang)，間斷(duan)現場(chang)(chang)拼裝(zhuang)(zhuang)，管節設(she)備位終了后回(hui)(hui)填。整(zheng)個流程包含(han)：根(gen)底的開挖、現場(chang)(chang)的拼裝(zhuang)(zhuang)、回(hui)(hui)填三個階段。

Before leaving factory, it is necessary to carry out hot-dip galvanizing anti-corrosion treatment for steel bellows, high-strength bolts and nuts. Every shipment is inspected and attached with product certificate. The steel bellows required for construction preparation are transported to the construction site after standardized consumption by the factory, assembled intermittently on site, and backfilled after the end of pipe joint equipment position. The whole process includes three stages: excavation of foundation, assembly on site and backfilling.

鋼波紋管

因為卷好的金屬波紋涵管長度較長，體積較大，一般是工程單位向廠方提規格、數量，由廠方帶設備及材料到施工現(xian)場加工。這樣既可大(da)大(da)減少波(bo)紋管的(de)損耗(hao)(短頭、碰傷(shang)、銹蝕(shi)等)，又能滿足需方的(de)各(ge)項要求，并(bing)節約(yue)經費。金屬波(bo)紋管現(xian)場卷制好后。

應(ying)存放(fang)在(zai)(zai)千(qian)燥(zao)場所，下(xia)面(mian)用檔(dang)(dang)距為1.6m的木(mu)板多檔(dang)(dang)架空，上面(mian)掩(yan)蓋防雨油布(bu)等隱(yin)瞞物，堆(dui)積高度不宜超越7m。與(yu)圓(yuan)管(guan)(guan)涵比較，波紋管(guan)(guan)涵的管(guan)(guan)側水(shui)平(ping)位移、撓度和對路途(tu)的擾動小，有(you)利于維護路面(mian)。管(guan)(guan)內切向與(yu)軸向應(ying)力應(ying)變以(yi)及撓度和大等效應(ying)力在(zai)(zai)恒載作用時隨(sui)填土(tu)高度的增加有(you)呈線(xian)性(xing)增加的規則。

活載作(zuo)用(yong)時隨填(tian)土(tu)的高度增加逐漸減小；總(zong)體(ti)上(shang)切(qie)向應變(bian)力應變(bian)大值大于(yu)軸向大值；管頂以切(qie)向應變(bian)為主(zhu)。金屬波紋管在運送(song)、裝(zhuang)卸過程中(zhong)，都要(yao)分外留神。不(bu)能翻滾或磕(ke)碰(peng)硬物，防止波紋管壁變(bian)形(xing)或損(sun)傷鍍鋅層。

鋼波紋管(guan)的運(yun)送與設備鋼波紋管(guan)通常選用工(gong)(gong)(gong)廠規范化消費，出廠時(shi)已間斷鍍鋅處置。用汽車運(yun)送工(gong)(gong)(gong)地(di)后(hou)，卸貨(huo)時(shi)不可直接翻拉，使用吊車合作人工(gong)(gong)(gong)間斷裝卸，防止損(sun)壞鍍鋅層(ceng)。操作關(guan)鍵運(yun)到工(gong)(gong)(gong)地(di)后(hou)，有(you)必要每塊查(cha)看尺度(du)，并從金(jin)屬波紋管(guan)中隨機抽取一(yi)片(pian)板件、高(gao)強(qiang)螺(luo)栓。

然后進行尺度、防腐、強度等項目的查驗。查驗數據應滿足相關要求。施工放樣涵洞施工前要片面熟諳規劃文件和規劃技術交底，現場核對涵洞的立體位置和角度，如有成績及時提出，施工便道建筑結束并能滿足施工需求。//hanihanbj.com/
