切開鋼波紋涵管要平直，制止切成斜口(kou)。卻不再縮短到本來長度，這種變(bian)型(xing)收(shou)叫(jiao)(jiao)做范性變(bian)型(xing)。由彈(dan)性變(bian)型(xing)點轉(zhuan)變(bian)為范性變(bian)型(xing)的(de)時間，叫(jiao)(jiao)做屈撓點，其代表符號是(shi)σb，單位(wei)是(shi)MPa或N/平方毫(hao)米。鋼波(bo)紋涵管選用標準化規劃，出產，規劃簡單，出產周(zhou)期短；工程實際造價比(bi)同類跨(kua)徑的(de)橋，涵洞低。

鋼(gang)波(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)管(guan)(guan)的防腐處理(li)需(xu)不(bu)低于必定的要求，以確保必定年(nian)限(xian)內鋼(gang)波(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)管(guan)(guan)具有足夠(gou)的耐侵蝕才能。鋼(gang)波(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)管(guan)(guan)接(jie)頭的方法：鋼(gang)波(bo)(bo)紋(wen)(wen)(wen)涵(han)(han)管(guan)(guan)接(jie)頭處要外包(bao)0.3米(mi)長的大號波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)，而且兩端頭要對半擰緊，中(zhong)心不(bu)得留(liu)有空位。為(wei)確保中(zhong)心不(bu)留(liu)空位，應在兩接(jie)頭端頭處做好符號。

做(zuo)(zuo)好后要用膠帶包裹嚴密，以防漏(lou)漿。抗張(zhang)強度在(zai)拉伸(shen)機的位(wei)力下，試(shi)樣被位(wei)長，在(zai)著手時試(shi)樣的伸(shen)長和張(zhang)力成正比(bi)，當(dang)張(zhang)力消除后試(shi)樣仍縮(suo)短到本來(lai)尺度，試(shi)樣的這種變(bian)型叫做(zuo)(zuo)彈性變(bian)型。考(kao)慮到頂板鋼波紋(wen)(wen)涵管(guan)數量在(zai)逐漸減少，但(dan)凡與(yu)鋼波紋(wen)(wen)涵管(guan)抵(di)觸的部件(jian)都要躲避波紋(wen)(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.
