鋼波紋管和高強(qiang)度螺栓、螺母，出廠前(qian)有必要(yao)進行熱鍍(du)鋅防腐處理。每走一批貨都(dou)查驗(yan)并附產品合格證。施工(gong)(gong)(gong)準備施工(gong)(gong)(gong)所需(xu)鋼波紋管由(you)工(gong)(gong)(gong)廠規范化(hua)消費后運送施工(gong)(gong)(gong)現(xian)場(chang)，間斷現(xian)場(chang)拼(pin)裝(zhuang)，管節設備位終了后回填。整個流程(cheng)包含：根底的(de)開挖、現(xian)場(chang)的(de)拼(pin)裝(zhuang)、回填三(san)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.
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(chang)加工。這樣既可大大減少波(bo)紋(wen)管的損耗(短(duan)頭、碰傷、銹蝕(shi)等(deng))，又能(neng)滿足需(xu)方的各項要求，并節約經費。金屬波(bo)紋(wen)管現(xian)場(chang)卷制好后。
應存放在(zai)千燥場所，下面(mian)用(yong)檔距(ju)為(wei)1.6m的(de)木(mu)板多檔架空，上面(mian)掩(yan)蓋防雨(yu)油(you)布等(deng)隱瞞物，堆積高度(du)(du)不宜超越7m。與圓管(guan)涵(han)(han)比較，波紋管(guan)涵(han)(han)的(de)管(guan)側(ce)水(shui)平位移、撓(nao)度(du)(du)和(he)對路途的(de)擾動小(xiao)，有利于維護路面(mian)。管(guan)內切向與軸(zhou)向應力(li)(li)應變以及(ji)撓(nao)度(du)(du)和(he)大等(deng)效(xiao)應力(li)(li)在(zai)恒載作用(yong)時隨填土高度(du)(du)的(de)增加有呈(cheng)線性(xing)增加的(de)規則。
活載作用(yong)時隨(sui)填土的高度(du)增加(jia)逐漸(jian)減小；總(zong)體上切向(xiang)應變(bian)力應變(bian)大(da)值(zhi)大(da)于軸向(xiang)大(da)值(zhi)；管(guan)(guan)頂(ding)以切向(xiang)應變(bian)為主。金屬(shu)波紋(wen)管(guan)(guan)在運送、裝(zhuang)卸過程中，都要(yao)分外留神(shen)。不能翻滾或磕碰硬物(wu)，防止波紋(wen)管(guan)(guan)壁變(bian)形或損傷鍍鋅層。
鋼波(bo)(bo)紋(wen)(wen)管(guan)的運送與設備(bei)鋼波(bo)(bo)紋(wen)(wen)管(guan)通(tong)常選用(yong)工(gong)廠規范(fan)化消(xiao)費，出(chu)廠時已間(jian)斷(duan)鍍鋅處置。用(yong)汽車運送工(gong)地后，卸貨時不可(ke)直接翻拉，使用(yong)吊車合作人工(gong)間(jian)斷(duan)裝卸，防止損壞鍍鋅層。操作關鍵運到(dao)工(gong)地后，有(you)必要每塊查看尺度(du)，并從(cong)金(jin)屬波(bo)(bo)紋(wen)(wen)管(guan)中(zhong)隨機(ji)抽取一片板件、高強螺栓。
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/
