切(qie)開鋼波紋涵管要(yao)平直，制止切成斜口(kou)。卻不(bu)再縮短(duan)到本來(lai)長度，這種變(bian)型收叫做范性變(bian)型。由彈性變(bian)型點(dian)轉變(bian)為范性變(bian)型的時間，叫做屈(qu)撓點(dian)，其代表符號是σb，單位是MPa或N/平方毫米。鋼波紋涵管選用標準化規劃，出產，規劃簡單，出產周期短(duan)；工程實際造價比同類跨徑的橋(qiao)，涵洞低。

做(zuo)(zuo)好后要(yao)用膠(jiao)帶包裹(guo)嚴密(mi)，以(yi)防(fang)漏漿。抗張強(qiang)度(du)在(zai)拉伸(shen)機的(de)位力下，試(shi)樣被(bei)位長(chang)，在(zai)著手時試(shi)樣的(de)伸(shen)長(chang)和張力成正比，當(dang)張力消除后試(shi)樣仍縮(suo)短(duan)到本來(lai)尺度(du)，試(shi)樣的(de)這(zhe)種變(bian)型(xing)叫做(zuo)(zuo)彈(dan)性變(bian)型(xing)。考慮到頂(ding)板(ban)鋼(gang)波紋涵(han)管數量在(zai)逐漸減(jian)少，但(dan)凡與鋼(gang)波紋涵(han)管抵觸的(de)部件都要(yao)躲(duo)避波紋管。

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.
