切(qie)開鋼波紋涵管要平直，制止切成斜口。卻不再縮短(duan)到本來(lai)長度(du)，這種變(bian)(bian)(bian)型(xing)收叫做范性變(bian)(bian)(bian)型(xing)。由彈性變(bian)(bian)(bian)型(xing)點轉(zhuan)變(bian)(bian)(bian)為(wei)范性變(bian)(bian)(bian)型(xing)的時間，叫做屈撓點，其代(dai)表符號是σb，單位是MPa或N/平方毫米(mi)。鋼波紋(wen)涵管選用標(biao)準化規劃，出(chu)產，規劃簡單，出(chu)產周(zhou)期(qi)短(duan)；工程實際造價比同(tong)類跨徑(jing)的橋，涵洞低(di)。

鋼(gang)波紋(wen)(wen)涵管(guan)(guan)的(de)(de)防腐(fu)處(chu)理需不(bu)低于(yu)必(bi)定的(de)(de)要求，以確保(bao)必(bi)定年限內鋼(gang)波紋(wen)(wen)涵管(guan)(guan)具有足夠的(de)(de)耐侵蝕(shi)才能(neng)。鋼(gang)波紋(wen)(wen)涵管(guan)(guan)接(jie)頭(tou)(tou)的(de)(de)方法：鋼(gang)波紋(wen)(wen)涵管(guan)(guan)接(jie)頭(tou)(tou)處(chu)要外包0.3米(mi)長(chang)的(de)(de)大(da)號波紋(wen)(wen)管(guan)(guan)，而(er)且兩端(duan)頭(tou)(tou)要對半擰緊，中心(xin)不(bu)得留有空位(wei)。為確保(bao)中心(xin)不(bu)留空位(wei)，應在兩接(jie)頭(tou)(tou)端(duan)頭(tou)(tou)處(chu)做好符號。

做好后要用膠(jiao)帶包(bao)裹嚴密，以防漏(lou)漿。抗張強度在(zai)拉伸(shen)機的位(wei)力(li)下，試(shi)樣(yang)被位(wei)長，在(zai)著手時試(shi)樣(yang)的伸(shen)長和張力(li)成正比，當張力(li)消除后試(shi)樣(yang)仍(reng)縮短到本來尺度，試(shi)樣(yang)的這種變型(xing)叫做彈性變型(xing)。考慮到頂板鋼(gang)波紋(wen)涵管(guan)數(shu)量在(zai)逐漸減少，但凡與鋼(gang)波紋(wen)涵管(guan)抵觸的部(bu)件都要躲避波紋(wen)管(guan)。

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.
