切開鋼波紋涵管要平直(zhi)，制止切成斜口。卻不再(zai)縮短(duan)(duan)到本來長度，這種(zhong)變(bian)(bian)(bian)型(xing)收(shou)叫(jiao)做范(fan)性變(bian)(bian)(bian)型(xing)。由彈性變(bian)(bian)(bian)型(xing)點(dian)轉變(bian)(bian)(bian)為范(fan)性變(bian)(bian)(bian)型(xing)的時間，叫(jiao)做屈撓點(dian)，其代表符號是σb，單位(wei)是MPa或(huo)N/平方毫米。鋼波紋涵(han)管選用標準(zhun)化規(gui)劃，出(chu)(chu)產，規(gui)劃簡單，出(chu)(chu)產周期短(duan)(duan)；工(gong)程(cheng)實際造價比同(tong)類跨徑的橋，涵(han)洞(dong)低。

鋼波(bo)紋(wen)(wen)(wen)涵管(guan)的防腐處理需不(bu)低于必定的要求，以確保必定年限內鋼波(bo)紋(wen)(wen)(wen)涵管(guan)具有足夠(gou)的耐侵蝕(shi)才能。鋼波(bo)紋(wen)(wen)(wen)涵管(guan)接頭的方(fang)法(fa)：鋼波(bo)紋(wen)(wen)(wen)涵管(guan)接頭處要外包0.3米(mi)長的大號波(bo)紋(wen)(wen)(wen)管(guan)，而且兩端(duan)頭要對半(ban)擰緊，中心(xin)不(bu)得留(liu)有空位。為確保中心(xin)不(bu)留(liu)空位，應在兩接頭端(duan)頭處做好符號。

做好后要(yao)用膠帶包裹嚴密，以防(fang)漏漿。抗(kang)張強度(du)在(zai)(zai)拉伸機的(de)位力下，試(shi)樣(yang)被位長，在(zai)(zai)著(zhu)手時試(shi)樣(yang)的(de)伸長和張力成正比，當(dang)張力消除后試(shi)樣(yang)仍(reng)縮短(duan)到本來尺度(du)，試(shi)樣(yang)的(de)這種變型叫做彈性變型。考慮(lv)到頂板鋼波(bo)紋涵(han)(han)管數量(liang)在(zai)(zai)逐(zhu)漸減少，但(dan)凡(fan)與鋼波(bo)紋涵(han)(han)管抵觸(chu)的(de)部(bu)件都要(yao)躲避(bi)波(bo)紋管。

After completion, it shall be tightly wrapped with adhesive tape to prevent slurry leakage. Tensile strength under the potential force of the tensile machine, the sample is lengthened. When starting, the elongation of the sample is directly proportional to the tension. When the tension is eliminated, the sample is still shortened to the original scale. This deformation of the sample is called elastic deformation. Considering that the number of steel corrugated culvert pipes on the top plate is gradually decreasing, all parts that conflict with steel corrugated culvert pipes should avoid corrugated pipes.
