切開鋼波紋涵管要平(ping)直，制止切成斜口。卻不(bu)再縮短到本來長度(du)，這種變(bian)型(xing)收(shou)叫(jiao)做(zuo)范性(xing)變(bian)型(xing)。由(you)彈性(xing)變(bian)型(xing)點(dian)轉變(bian)為范性(xing)變(bian)型(xing)的(de)時間(jian)，叫(jiao)做(zuo)屈撓點(dian)，其(qi)代表(biao)符號是(shi)(shi)σb，單位是(shi)(shi)MPa或N/平(ping)方毫米(mi)。鋼(gang)波紋(wen)涵管選用標準化(hua)規(gui)劃，出產(chan)，規(gui)劃簡單，出產(chan)周期(qi)短；工程實際造價比(bi)同類(lei)跨徑的(de)橋，涵洞低。

鋼波(bo)(bo)紋(wen)涵(han)管(guan)(guan)的防(fang)腐處(chu)理需不(bu)低于必定(ding)的要求，以(yi)確(que)保必定(ding)年限內鋼波(bo)(bo)紋(wen)涵(han)管(guan)(guan)具有(you)足夠的耐(nai)侵(qin)蝕(shi)才能(neng)。鋼波(bo)(bo)紋(wen)涵(han)管(guan)(guan)接頭的方(fang)法：鋼波(bo)(bo)紋(wen)涵(han)管(guan)(guan)接頭處(chu)要外包0.3米長的大號波(bo)(bo)紋(wen)管(guan)(guan)，而且兩(liang)(liang)端頭要對(dui)半擰(ning)緊，中心不(bu)得留有(you)空位(wei)(wei)。為確(que)保中心不(bu)留空位(wei)(wei)，應在(zai)兩(liang)(liang)接頭端頭處(chu)做好符號。

做好(hao)后要用膠(jiao)帶包(bao)裹嚴(yan)密，以防漏漿。抗張(zhang)強(qiang)度在(zai)拉伸機的位(wei)力下(xia)，試樣被位(wei)長，在(zai)著(zhu)手時試樣的伸長和張(zhang)力成正比，當張(zhang)力消除(chu)后試樣仍(reng)縮短到本來尺度，試樣的這(zhe)種變(bian)型(xing)叫做彈性變(bian)型(xing)。考慮(lv)到頂板鋼波(bo)(bo)紋(wen)涵管(guan)數量在(zai)逐漸減少(shao)，但凡與鋼波(bo)(bo)紋(wen)涵管(guan)抵(di)觸的部件都(dou)要躲避波(bo)(bo)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.
